Reply to Chris Allen. Thanks for the comment Chris. Best wishes with your new business! After reading this post, I guess you must have had a general understanding on FAT32 partition size limit, and the ways to break these limits. Why not get rid of FAT32 size limit right now to enjoy Blu-ray movies and big games as you wish? We believe you will make a wise choice. Download Partition Wizard. Summary : What is FAT32 partition size limit?

So, you don't need to worry whether it works normally in Windows. Note: You are likely to see the Data error cyclic redundancy check message in the end. But please don't worry, for your partition is already converted to NTFS. You can go to Disk management to check.

Hence it can suppprt a maximum file size of 4GB. For example, data sources for the Oracle Application Server 10 g are set to route to a service. For Oracle E-Business Suite, the service is also maintained in the application database identifier and in the cookie for the ICX parameters. Server-side work, such as the Oracle Scheduler, parallel execution, and Oracle Streams Advanced Queuing, set the service name as part of the workload definition. For the Oracle Scheduler, the service that the job class uses is defined when the job class is created.

During execution, jobs are assigned to job classes, and job classes run within services. Using services with job classes ensures that the work executed by the job scheduler is identified for workload management and performance tuning.

For parallel query and parallel DML, the query coordinator connects to a service just like any other client. The parallel query processes inherit the service for the duration of the execution. At the end of query execution, the parallel execution processes revert to the default service.

After you create a database, the instance is left running, and the database is open and available for normal database use. You may want to perform other actions, some of which are discussed in this section.

After the database is created, you can configure it to take advantage of Oracle Identity Management. Additional administrative accounts are provided by Oracle Database that should be used only by authorized users. To protect these accounts from being used by unauthorized users familiar with their Oracle-supplied passwords, these accounts are initially locked with their passwords expired. As the database administrator, you are responsible for the unlocking and resetting of these accounts.

Table lists the administrative accounts that are provided by Oracle Database. Not all accounts may be present on your system, depending upon the options that you selected for your database.

Transparent data encryption is a feature that enables encryption of database columns before storing them in the datafile. If users attempt to circumvent the database access control mechanisms by looking inside datafiles directly with operating system tools, transparent data encryption prevents such users from viewing sensitive information.

The data is encrypted in the data files and in the audit logs if audit is turned on. Database users with appropriate privileges can view the data in unencrypted format. For information on enabling and disabling transparent data encryption, see Oracle Database Security Guide.

For large-scale deployments where applications use password credentials to connect to databases, it is possible to store such credentials in a client-side Oracle wallet. An Oracle wallet is a secure software container that is used to store authentication and signing credentials. Storing database password credentials in a client-side Oracle wallet eliminates the need to embed usernames and passwords in application code, batch jobs, or scripts.

This reduces the risk of exposing passwords in the clear in scripts and application code, and simplifies maintenance because you need not change your code each time usernames and passwords change. In addition, not having to change application code also makes it easier to enforce password management policies for these user accounts.

When you configure a client to use the external password store, applications can use the following syntax to connect to databases that use password authentication:.

Instead your system looks for database login credentials in the client wallet. The Oracle Database distribution media includes various SQL files that let you experiment with the system, learn SQL, or create additional tables, views, or synonyms. Oracle Database includes sample schemas that help you to become familiar with Oracle Database functionality.

All Oracle Database documentation and training materials are being converted to the Sample Schemas environment as those materials are updated. The Sample Schemas can be installed automatically by the Database Configuration Assistant, or you can install them manually. The schemas and installation instructions are described in detail in Oracle Database Sample Schemas. In addition to the views listed previously in "Viewing Parameter Settings" , you can view information about your database content and structure using the following views:.

Upgrade an existing database. The remainder of this chapter discusses creating a database manually. Manually Creating an Oracle Database This section takes you through the planning stage and the actual creation of the database.

Considerations Before Creating the Database Database creation prepares several operating system files to work together as an Oracle Database. The following topics can help prepare you for database creation. Table lists some recommended actions: Table Database Planning Tasks Action Additional Information Plan the database tables and indexes and estimate the amount of space they will require.

Oracle Database Performance Tuning Guide Your Oracle operating system specific documentation Consider using Oracle-managed files and Automatic Storage Management to create and manage the operating system files that make up your database storage. Part III, "Automated File and Storage Management" Select the global database name , which is the name and location of the database within the network structure. You can also specify an alternate character set. Chapter 10, "Managing the Undo Tablespace" Develop a backup and recovery strategy to protect the database from failure.

Chapter 3, "Starting Up and Shutting Down". Meeting Creation Prerequisites Before you can create a new database, the following prerequisites must be met: The desired Oracle software must be installed. Sufficient memory must be available to start the Oracle Database instance. Creating the Database This section presents the steps involved when you create a database manually. The examples shown in these steps create an example database mynewdb.

Notes: The steps in this section contain cross-references to other parts of this book and to other books. Step 2: Establish the Database Administrator Authentication Method You must be authenticated and granted appropriate system privileges in order to create a database.

Database administrator authentication and authorization is discussed in the following sections of this book: "Database Administrator Security and Privileges" "Database Administrator Authentication" "Creating and Maintaining a Password File". Step 3: Create the Initialization Parameter File When an Oracle instance starts, it reads an initialization parameter file. Step 6: Start the Instance Start an instance without mounting a database. Note: You can set several limits during database creation.

Some of these limits are limited by and affected by operating system limits. Step 8: Create Additional Tablespaces To make the database functional, you need to create additional files and tablespaces for users.

SQL Creates the views of the data dictionary tables, the dynamic performance views, and public synonyms for many of the views. Step Back Up the Database. See Also: "Some Security Considerations". This is discussed in Oracle Database Upgrade Guide. In this case the database creates a default temporary tablespace.

Supporting Bigfile Tablespaces During Database Creation Oracle Database simplifies management of tablespaces and enables support for ultra-large databases by letting you create bigfile tablespaces. See Also: "Bigfile Tablespaces" for more information about bigfile tablespaces. If you are already using the smaller time zone file and you want to continue to use it in an Oracle Database 10 g environment or if you want to use the smaller time zone file instead of the default time zone file, then complete the following tasks: Shut down the database.

Restart the database. All databases that share information must use the same time zone datafile. How serious is the damage if unlogged direct writes cannot be recovered? Is the performance degradation caused by forced logging tolerable? Understanding Initialization Parameters When an Oracle instance starts, it reads initialization parameters from an initialization parameter file.

See Also: Oracle Database Reference for descriptions of all initialization parameters including their default settings. Determining the Global Database Name The global database name consists of the user-specified local database name and the location of the database within a network structure.

Specifying a Flash Recovery Area A flash recovery area is a location in which Oracle Database can store and manage files related to backup and recovery. In a RAC environment, the settings for these two parameters must be the same on all instances. Therefore, consider specifying a block size larger than your operating system block size if the following conditions exist: Oracle Database is on a large computer system with a large amount of memory and fast disk drives. See Also: Your operating system specific Oracle documentation for details about the default block size.

Components and Granules in the SGA The SGA comprises a number of memory components , which are pools of memory used to satisfy a particular class of memory allocation requests. Do one of the following: For more complete automatic tuning, set the values of the automatically sized SGA components listed in Table to zero. Setting Minimums for Automatically Sized SGA Components You can exercise some control over the size of the automatically sized SGA components by specifying minimum values for the parameters corresponding to these components.

Automatic Tuning and the Shared Pool When the automatic shared memory management feature is enabled, the internal tuning algorithm tries to determine an optimal size for the shared pool based on the workload.

Modifying Parameters for Manually Sized Components Parameters for manually sized components can be dynamically altered as well. Setting the Buffer Cache Initialization Parameters The buffer cache initialization parameters determine the size of the buffer cache component of the SGA.

This view summarizes information based on all completed SGA resize operations since instance startup. A resize operation is an enlargement or reduction of a dynamic SGA component. Specifying the Method of Undo Space Management Every Oracle Database must have a method of maintaining information that is used to undo changes to the database. Note: For Oracle Database 10 g Release 2 The minimum value is 9. If you create an Oracle Database using the default value, you can immediately use all the new features in this release, and you can never downgrade the database.

Setting the License Parameter Note: Oracle no longer offers licensing by the number of concurrent sessions. Note: This mechanism assumes that each person accessing the database has a unique user name and that no people share a user name. Therefore, so that named user licensing can help you ensure compliance with your Oracle license agreement, do not allow multiple users to log in using the same user name.

Troubleshooting Database Creation If database creation fails, you can look at the alert log to determine the reason for the failure and to determine corrective action. Dropping a Database Dropping a database involves removing its datafiles, redo log files, control files, and initialization parameter files. The database must be mounted exclusively--not in shared mode. Managing Initialization Parameters Using a Server Parameter File Initialization parameters for the Oracle Database have traditionally been stored in a text initialization parameter file.

What Is a Server Parameter File? Caution: Although you can open the binary server parameter file with a text editor and view its text, do not manually edit it. NET version 4. For more information, Site and site system prerequisites.

Skip to main content. This browser is no longer supported. Download Microsoft Edge More info. Consider a simple example: let's say you wanted JMeter to "spider" through your site, hitting link after link parsed from the HTML returned from your server this is not actually the most useful thing to do, but it serves as a good example. This will cause your test sample to match with any link found on the returned pages. If you wanted to restrict the spidering to a particular domain, then change the domain value to the one you want.

Then, only links to that domain will be followed. A more useful example: given a web polling application, you might have a page with several poll options as radio buttons for the user to select. Let's say the values of the poll options are very dynamic - maybe user generated. If you wanted JMeter to test the poll, you could either create test samples with hardcoded values chosen, or you could let the HTML Link Parser parse the form, and insert a random poll option into your URL test sample.

Put in hard-coded values for the domain , path , and any additional form parameters. When the modifier examines this URL test sample, it will find that it "matches" the poll form and it shouldn't match any other form, given that you've specified all the other aspects of the URL test sample , and it will replace your form parameters with the matching parameters from the form. Since the regular expression ". It will choose at random, and replace the value in your URL test sample. Each time through the test, a new random value will be chosen.

Simply give it the name of the session id parameter, and it will find it on the page and add the argument to every request of that ThreadGroup. Alternatively, this modifier can be attached to select requests and it will modify only them. User Variables can also be specified in the Test Plan but not specific to individual threads.

This panel allows you to specify a series of values for any User Variable. For each thread, the variable will be assigned one of the values from the series in sequence. If there are more threads than values, the values get re-used. For example, this can be used to assign a distinct user id to be used by each thread. User variables can be referenced in any field of any JMeter Component.

The variable is specified by clicking the Add Variable button in the bottom of the panel and filling in the Variable name in the ' Name: ' column. To add a new value to the series, click the ' Add User ' button and fill in the desired value in the newly added column.

RegEx User Parameters are specific to individual threads. This component allows you to specify reference name of a regular expression that extracts names and values of HTTP request parameters. Regular expression group numbers must be specified for parameter's name and also for parameter's value. Replacement will only occur for parameters in the Sampler that uses this RegEx User Parameters which name matches.

Suppose we have a request which returns a form with 3 input parameters and we want to extract the value of 2 of them to inject them in next request. See also the Regular Expression Extractor element, which is used to extract parameters names and values. This Pre-Processor schedules a timer task to interrupt a sample if it takes too long to complete. The timeout is ignored if it is zero or negative. For this to work, the sampler must implement Interruptible.

The test element is intended for use where individual timeouts such as Connection Timeout or Response Timeout are insufficient, or where the Sampler does not support timeouts. The timeout should be set sufficiently long so that it is not triggered in normal tests, but short enough that it interrupts samples that are stuck. This executes in the same thread as the timer, so if the interrupt takes a long while, it may delay the processing of subsequent timeouts. This is not expected to be a problem, but if necessary the property InterruptTimer.

As the name suggests, Post-Processors are applied after samplers. Note that they are applied to all the samplers in the same scope, so to ensure that a post-processor is applied only to a particular sampler, add it as a child of the sampler. Post-Processors are run before Assertions, so they do not have access to any Assertion Results, nor will the sample status reflect the results of any Assertions. If you require access to Assertion Results, try using a Listener instead.

Also note that the variable JMeterThread. Allows the user to extract values from a server response using a Perl-type regular expression. As a post-processor, this element will execute after each Sample request in its scope, applying the regular expression, extracting the requested values, generate the template string, and store the result into the given variable name.

However, if you have several test elements that set the same variable, you may wish to leave the variable unchanged if the expression does not match.

In this case, remove the default value once debugging is complete. If the match number is set to a non-negative number, and a match occurs, the variables are set as follows:. If no match occurs, then the refName variable is set to the default unless this is absent.

Also, the following variables are removed:. If the match number is set to a negative number, then all the possible matches in the sampler data are processed. The variables are set as follows:. Note that the refName variable is always set to the default value in this case, and the associated group variables are not set. See also Response Assertion for some examples of how to specify modifiers, and for further information on JMeter regular expressions. Note that the refName variable is always set to the default value in this case.

XPath2 Extractor provides some interestings tools such as an improved syntax and much more functions than in it's first version. To see more information about these functions, please check xPath2 functions. To allow for use in a ForEach Controller , the following variables are set on return:. However it is useful as generic query language for structured data too. Here are few examples:. It is described in an ABNF grammar with a complete specification.

This ensures that the language syntax is precisely defined. This post processor is very similar to Regular expression extractor. Allows the user to extract values from a server response using left and right boundaries. As a post-processor, this element will execute after each Sample request in its scope, testing the boundaries, extracting the requested values, generate the template string, and store the result into the given variable name. Static variables can be defined for values that are repeated throughout a test, such as server names.

This simplifies changing the name later. If the same variable name is reused on one of more User Defined Variables Configuration elements, the value is set to the last definition in the test plan reading from top to bottom.

Such variables should be used for items that may change between test runs, but which remain the same during a test run. Note that the Test Plan cannot refer to variables it defines.

If you need to construct other variables from the Test Plan variables, use a User Defined Variables test element. This increases the resources needed to run a test, and may adversely impact JMeter performance. If more data is required for a particular sampler only, then add a Listener to it, and configure the fields as required.

The option does not affect CSV result files, which cannot currently store such information. Also, an option exists here to instruct JMeter to run the Thread Group serially rather than in parallel.

Run tearDown Thread Groups after shutdown of main threads: if selected, the tearDown groups if any will be run after graceful shutdown of the main threads. The tearDown threads won't be run if the test is forcibly stopped. Test plan now provides an easy way to add classpath setting to a specific test plan. The feature is additive, meaning that you can add jar files or directories, but removing an entry requires restarting JMeter.

However it can be useful for utility jars such as JDBC drivers. The jars are only added to the search path for the JMeter loader, not for the system class loader. JMeter properties also provides an entry for loading additional classpaths. A Thread Group defines a pool of users that will execute a particular test case against your server. In the Thread Group GUI, you can control the number of users simulated number of threads , the ramp up time how long it takes to start all the threads , the number of times to perform the test, and optionally, a start and stop time for the test.

Note that the condition is only checked between samples; when the end condition is reached, that thread will stop. JMeter does not interrupt samplers which are waiting for a response, so the end time may be delayed arbitrarily. A popup menu will appear: Popup menu to start a selection of Thread Groups Notice you have three options to run the selection of Thread Groups: Start Start the selected thread groups only Start no pauses Start the selected thread groups only but without running the timers Validate Start the selected thread groups only using validation mode.

Per default this runs the Thread Group in validation mode see below Validation Mode: This mode enables rapid validation of a Thread Group by running it with one thread, one iteration, no timers and no Startup delay set to 0.

Behaviour can be modified with some properties by setting in user. Defaults to false. It is only needed if you have not set up the appropriate System properties. There is a feature of the JSSE libraries that require you to have at least a six character password on your key at least for the keytool utility that comes with your JDK.

You will be presented with a file finder that looks for PKCS12 files by default. Your PKCS12 file must have the extension '. Any other file will be treated like an average JKS key store. If JSSE is correctly installed, you will be prompted for the password. The text box does not hide the characters you type at this point -- so make sure no one is looking over your shoulder.

The current implementation assumes that the password for the keystore is also the password for the private key of the client you want to authenticate as. Or you can set the appropriate System properties - see the system. The next time you run your test, the SSL Manager will examine your key store to see if it has at least one key available to it. If there is only one key, SSL Manager will select it for you.

If there is more than one key, it currently selects the first key. There is currently no way to select other entries in the keystore, so the desired key must be the first. This file will be read before the " cacerts " file in the same directory. Keep in mind that as long as the " jssecacerts " file exists, the certificates installed in " cacerts " will not be used.

This may cause problems for you. If you don't mind importing your CA certificate into the " cacerts " file, then you can authenticate against all of the CA certificates installed.

JMeter will create test sample objects and store them directly into your test plan as you go so you can view samples interactively while you make them.

Ensure you read this wiki page to setup correctly JMeter. Ideally use private browsing mode when recording the session. This should ensure that the browser starts with no stored cookies, and prevents certain changes from being saved.

For example, Firefox does not allow certificate overrides to be saved permanently. HTTPS connections use certificates to authenticate the connection between the browser and the web server.

To authenticate the certificate, the browser checks that the server certificate is signed by a Certificate Authority CA that is linked to one of its in-built root CAs. Browsers also check that the certificate is for the correct host or domain, and that it is valid and not expired. If any of the browser checks fail, it will prompt the user who can then decide whether to allow the connection to proceed. Effectively JMeter has to pretend to be the target server. JMeter will generate its own certificate s.

These are generated with a validity period defined by the property proxy. If JMeter detects that it is running under Java 8 or later, it will generate certificates for each target server as necessary dynamic mode unless the following property is defined: proxy.

When using dynamic mode, the certificate will be for the correct host name, and will be signed by a JMeter-generated CA certificate.

By default, this CA certificate won't be trusted by the browser, however it can be installed as a trusted certificate. Once this is done, the generated server certificates will be accepted by the browser. This has the advantage that even embedded HTTPS resources can be intercepted, and there is no need to override the browser checks for each new server.

Browsers don't prompt for embedded resources. So with earlier versions, embedded resources would only be downloaded for servers that were already 'known' to the browser. Unless a keystore is provided and you define the property proxy. JMeter includes code to check that keytool is available by looking in various standard places.

If JMeter is unable to find the keytool application, it will report an error. If necessary, the system property keytool. This should be defined in the file system. The JMeter certificates are generated if necessary when the Start button is pressed. Certificate generation can take some while, during which time the GUI will be unresponsive.

The cursor is changed to an hour-glass whilst this is happening. When certificate generation is complete, the GUI will display a pop-up dialogue containing the details of the certificate for the root CA. This certificate needs to be installed by the browser in order for it to accept the host certificates generated by JMeter; see below for details. This certificate is not one of the certificates that browsers normally trust, and will not be for the correct host.

As a consequence:. Versions of JMeter from 2. As mentioned above, when run under Java 8, JMeter can generate certificates for each server. For this to work smoothly, the root CA signing certificate used by JMeter needs to be trusted by the browser. The first time that the recorder is started, it will generate the certificates if necessary. When the certificates have been set up, JMeter will show a dialog with the current certificate details. At this point, the certificate can be imported into the browser, as per the instructions below.

Note that once the root CA certificate has been installed as a trusted CA, the browser will trust any certificates signed by it. Until such time as the certificate expires or the certificate is removed from the browser, it will not warn the user that the certificate is being relied upon.

So anyone that can get hold of the keystore and password can use the certificate to generate certificates which will be accepted by any browsers that trust the JMeter root CA certificate. For this reason, the password for the keystore and private keys are randomly generated and a short validity period used. The passwords are stored in the local preferences area. Please ensure that only trusted users have access to the host with the keystore. During recording, the browser will follow a redirect response and generate an additional request.

The Proxy will record both the original request and the redirected request subject to whatever exclusions are configured. The generated samples have " Follow Redirects " selected by default, because that is generally better.

Redirects may depend on the original request, so repeating the originally recorded sample may not always work. Now if JMeter is set to follow the redirect during replay, it will issue the original request, and then replay the redirect request that was recorded. To avoid this duplicate replay, JMeter tries to detect when a sample is the result of a previous redirect.

When the next request is received, it is compared with the saved redirect URL and if there is a match, JMeter will disable the generated sample. It also adds comments to the redirect chain. This assumes that all the requests in a redirect chain will follow each other without any intervening requests. To disable the redirect detection, set the property proxy.

The include and exclude patterns are treated as regular expressions using Jakarta ORO. They will be matched against the host name, port actual or implied , path and query if any of each browser request. Thus, if you want to include all.

If there are any include patterns, then the URL must match at least one of the patterns , otherwise it will not be recorded. If there are any exclude patterns, then the URL must not match any of the patterns , otherwise it will not be recorded. Using a combination of includes and excludes, you should be able to record what you are interested in and skip what you are not.

To configure which content-types are treated as binary, update the JMeter property proxy. The default settings are as follows:. It is also possible to have the proxy add timers to the recorded script. The proxy will place a copy of this timer into each sample it records, or into the first sample of each group if you're using grouping.

JMeter places the recorded samples in the Target Controller you choose. If you choose the default option " Use Recording Controller ", they will be stored in the first Recording Controller found in the test object tree so be sure to add a Recording Controller before you start recording.

If the Proxy does not seem to record any samples, this could be because the browser is not actually using the proxy. To check if this is the case, try stopping the proxy.

If the browser still downloads pages, then it was not sending requests via the proxy. Double-check the browser options. If you are trying to record from a server running on the same host, then check that the browser is not set to " Bypass proxy server for local addresses " this example is from IE7, but there will be similar options for other browsers. If the HTTP S Test Script Recorder finds enabled HTTP Request Defaults directly within the controller where samples are being stored, or directly within any of its parent controllers, the recorded samples will have empty fields for the default values you specified.

Similarly, if the HTTP S Test Script Recorder finds User Defined Variables UDV directly within the controller where samples are being stored, or directly within any of its parent controllers, the recorded samples will have any occurrences of the values of those variables replaced by the corresponding variable.

To avoid this happening everywhere, set the " Regex Matching " check-box. This tells the proxy server to treat values as Regexes using the perl5 compatible regex matchers provided by ORO. That way each match will start and end at a word boundary. If you don't want your regex to be enclosed with those boundary matchers, you have to enclose your regex within parens, e.

Look out for overlapping matchers. For example the value. If there are any problems interpreting any variables as patterns, these are reported in jmeter. When you are done recording your test samples, stop the proxy server hit the " stop " button. Remember to reset your browser's proxy settings. Now, you may want to sort and re-order the test script, add timers, listeners, a cookie manager, etc.

You can also add a Save Responses to a file Post-Processor which will save the responses to files. If you define the property proxy. Note that there may be more responses than samplers if excludes or includes have been used.

If the server you are testing against uses cookies, remember to add an HTTP Cookie Manager to the test plan when you have finished recording it. During recording, the browser handles any cookies, but JMeter needs a Cookie Manager to do the cookie handling during a test run.

The JMeter Proxy server passes on all cookies sent by the browser during recording, but does not save them to the test plan because they are likely to change between runs. Otherwise Authorization Manager will be added to target controller with authorization object. You may have to fix automatically computed values after recording. Some browsers e. Firefox and Opera don't include the full name of a file when uploading files.

This can cause the JMeter proxy server to fail. One solution is to ensure that any files to be uploaded are in the JMeter working directory, either by copying the files there or by starting JMeter in the directory containing the files. Although JMeter does not provide a native proxy implementation to record these protocols, you have the ability to record these protocols by implementing a custom SamplerCreator.
