Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Click Edit Data Source next to the Connection Pool field. Otherwise, the default initialization SQL for the database type is used. Why do you need to use session or request variables? Only repository variables can be used in the definition. Data Type Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. In the left pane, select Initialization Blocks under Repository or Session, depending on whether you want to enable or disable repository initialization blocks or session initialization blocks. This chapter describes how to use variables in the Oracle BI repository to streamline administrative tasks and dynamically modify metadata content to adjust to a changing data environment. If the SQL statement contains an error, the database returns an error message. For example, the following CASE statement is identical to the one explained in the preceding example, except that variables have been substituted for the constants: You cannot use variables to represent columns or other repository objects. In order to create an OBIEE Analytics Agent, you have to connect to Oracle BI Analytics: This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. Privacy Policy Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". To create a multi-source session variable, you first create row-wise initialization blocks for each source. To add a Default initializer value, type the value in the Default initializer box, or click the Expression Builder button to use Expression Builder. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. 2. Design Pattern, Infrastructure Http For Example the report looks like this Region VALUEOF (REGION) SALES North Some value from North Variable 100 When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. The values of session variables are established when a user logs in to OBIEE, and the same session variable may have a different value for each user. a fiscal calendar) that you have stored in a Periods table, you can write the analogous SQL for that calendar. Key/Value You could then set a security filter for all members of a group that would allow them to view only data pertinent to their region. It seems that OBIEE save the default initializer value in the same space than for a repository variable. The next step is to establish execution precedence. To create a new initialization block, click New. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. This option enables you to change this property without opening the initialization block dialog. While the main focus of this section is on the definition and usage of multi-source session variables, you may also select the VALUEOF the component session variables in logical queries and data filters. This variable has a value of Yes. Init block 'B_blk' does not have "Allowed deferred execution" flag set. https://docs.oracle.com/cd/E28280_01/bi.1111/e10540/variables.htm#BIEMG3104 Share Improve this answer Follow If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. The string you enter here is processed by the Oracle BI Server, and therefore as long as it is supported by the Oracle BI Server, the string will work with different data sources. Close the Variable Manager and save the repository. OBIEE 11g - The session variable, NQ_SESSION.VARIABLE, has no value definition user11173172 Feb 20 2015 edited Feb 27 2015 Hello, I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. If you selected Dynamic, use the Initialization Block list to select an existing initialization block that will be used to refresh the value on a continuing basis. This variable has a possible value of 0 or 1. I have created variables with the same name using row vise initialization. You need to describe the content of these sources on the Content tab of the Logical Table Source dialog. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. Statistics See "Creating Initialization Blocks" for more information. For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Nominal Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Rather than entering the numbers 17 and 23 into this expression as constants, you could use the Variable tab of the Variable dialog to set up a static repository variable named prime_begin and initialize it to a value of 17, and create another variable named prime_end and initialize it to a value of 23. In the [Repository|Session] Variable Initialization Block dialog, click Edit Execution Precedence. If you order a special airline meal (e.g. Data Type 1. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. The Oracle BI Server can also provide functions (such as PI) that might not be available in the data source, and the SQL statement will work with other data sources supported by the Oracle BI Server (for example, ADF, SQL Server, Oracle, and XML files). In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables and removing the NQS_PASSWORD_CLAUSE clause. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Used for Oracle BI Presentation Services. Legacy groups are mapped to application roles automatically. [emailprotected] repository. The new value is only valuable for the query. See "Examples of Initialization Strings" for additional examples. Operating System This SQL contains two constraints in the WHERE clause: ':USER' (note the colon and single quotes) is the ID the user types when logging in. This system session variable overrides a variable defined in the Users object in the Administration Tool. You can find an example of a dynamic essbase connection pool in this post of christian berg: In the bookshel Version 10.1.3.2, it's written that Only repository variables can be used in the definition. Names for all variables should be unique. Then, in the Browse dialog, select the variable to be refreshed by this initialization block and click OK. For the Custom Authenticator data source type (Session variables only), the variable USER is required. Function Linear Algebra Database: For repository and session variables. You also set up a schedule that the Oracle BI Server will follow to execute the query and periodically refresh the value of the variable. Number Used for Oracle BI Server. This variable has a possible value of 0 or 1. What are some tools or methods I can purchase to trace a water leak? File System See "About Row-Wise Initialization" for more information. For example, here are dates as set by the default values in the prompt. In the Administration Tool, select Manage, then select Variables. See "About Connection Pools for Initialization Blocks" for more information. If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). Color See <> for more information. In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. Contains the application roles to which the user belongs. Table 19-2 Sample Session Variables Database Table. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. Order Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. If you do not want this to occur, use the Undo Check Out option. The Oracle BI Server logs all SQL queries issued to retrieve repository variable information in nqquery.log when the logging level for the administrator account (set upon installation) is set to 2 or higher. Data Quality Note: The Allow deferred execution option is unavailable in some circumstances. To assign a name and schedule to initialization blocks: In the Variable Manager dialog, from the Action menu, choose New > Repository (or Session) > Initialization Block. Used for Oracle BI Presentation Services. If the SQL statement contains an error, the database returns an error message. Not the answer you're looking for? If you selected Use database specific SQL, then in the Database pane, expand and select the database. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. ':PASSWORD' (note the colon and the single quotes) is the password the user enters. To view full details, sign in to My Oracle Support Community. The only way I can actually address the other two values to set the default value, is through the default selection type 'sql result', in which I look up the variable value using the dimension to which it refer: WHERE "dimension". For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. The Use caching option is automatically selected when you select the Row-wise initialization option. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. I need it to be the values of TestVar1 and TestVar3, that were applied in a previous prompt as request variables, multiplied, but all I get is the original values from the session variables. Time The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements (for example, figures such as GIF files). Dates are, frankly, inordinately messy in OBIEE. DataBase Process (Thread) In the User/Application Role Permissions dialog, click the Data Filters tab. The names of system session variables are reserved and cannot be used for other types of variables. In the Session Variable dialog, type a variable name. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. OBIEE - Where can I use a BI Server variable (session/repository) ? If you stop and restart the Oracle BI Server, the server automatically executes the SQL statement in the repository variable initialization blocks, re-initializing the repository variables. ), #business-intelligence-suite-enterprise-edition-obiee. Holds the Oracle BI Presentation Services user interface display language. Don't have a My Oracle Support Community account? Lexical Parser Used to enable or disable Oracle BI Server subrequest cache hits and seeding. In addition, if an initialization block fails for a particular connection pool during Oracle BI Server start-up, no more initialization blocks using that connection pool are processed. Click Link to associate an existing variable with an initialization block. You use the same procedure to define nonsystem session variables as for system session variables. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. See "About Connection Pools for Initialization Blocks" for more information.
