Web Services Contains the time zone of the user, typically populated from the LDAP profile of the user. 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. If you initialize a variable using a character string, enclose the string in single quotes ( ' ). Monitoring For example, suppose a repository has two initialization blocks, A and B. Not the answer you're looking for? Used for Oracle BI Presentation Services. Users can select a language on the sign-in page for Oracle BI EE, or they can change the language setting on the Preferences tab of the My Account dialog after signing in. This chapter contains the following topics: Working with Multi-Source Session Variables. Quick question, a colleague of mine was telling me that the session variable, NQ_SESSION.GROUP, only shows groups which are assigned at the presentation >> level (or passed in from LDAP or other data source) but it does not show any of the group assignments made within the RPD itself. Data Analysis For example, suppose you want to create an expression to group times of day into different day segments. For information about using session variables when setting up security, see "Managing Session Variables" in Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition. Table 19-2 Sample Session Variables Database Table. Data Warehouse Otherwise, in the Default initialization string box, type the SQL initialization string needed to populate the variables. Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. Data Persistence When Jane connects to the Oracle BI Server, her session contains three session variables from row-wise initialization: LEVEL, containing the value 8; STATUS, containing the value FULL-TIME; and GRADE, containing the value AAA. An error will generate if a session variable is used. Infra As Code, Web This is another system variable whose presence is always assumed when the USER system session variable is used. The multi-source session variable will fail only if all of the component initialization blocks return null values. COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . separate catalog. This variable is typically populated from the LDAP profile of the user. Used to enable or disable Oracle BI Server plan cache seeding. In the Browse dialog, select the blocks that should be initialized before the block that you have open, and then click OK. To remove a block, in the [Repository|Session] Variable Initialization Block Execution Precedence dialog, select the block you want to remove and click Remove. But when User B logs in he sees below error , when running the same report, [nQSError: 23006] The session variable, NQ_SESSION.PRODUCT, has no value definition. "USER"), the syntax works. Why must a product of symmetric random variables be symmetric? I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. Nominal The Dynamic Name tab is not active unless at least one session variable is defined. This section provides information about working with repository variables, and contains the following topics: A repository variable has a single value at any point in time. Versioning Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, How to Use Variable Expression for Default Value of Dashboard Prompt in OBIEE 11g, The open-source game engine youve been waiting for: Godot (Ep. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. If you are using a calendar thats different from the normal Gregorian calendar (i.e. biServer is good where biserver is not good. The SQL statement must reference physical tables that can be accessed using the connection pool specified in the Connection Pool field in the Initialization Block dialog. Exists only for compatibility with previous releases. Used to enable or disable Oracle BI Server result cache hits. Lexical Parser was shown. 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. Not correct. You cannot use any other value or expression as the default initializer for a static repository variable. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. OAuth, Contact Used to enable or disable Oracle BI Server result cache seeding. Spatial You can also use this variable in a SQL statement. 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). Used to enable or disable Oracle BI Server subrequest cache hits and seeding. However, the cached results might not contain the most current session variable values. 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. Instead, the connection pool is blacklisted and subsequent initialization blocks for that connection pool are skipped. Because of this, do not put sensitive data like passwords in session or repository variables. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'A' which is security sensitive.". Why is the error occurring only for User B? A common use for nonsystem session variables is setting user filters. Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. Based on products assigned to user in security table, data filter is applied. Grammar The Variable Manager appears. Contains the groups to which the user belongs. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. If you select this option, this initialization block must succeed for users to log in.

Collection It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. You can then use this variable in a filter, as shown in the following WHERE clause: The variable LIST_OF_USERS contains a list of values, that is, one or more values. 3. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Tree Function Scripting on this page enhances content navigation, but does not change the content in any way. Contains the application roles to which the user belongs. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. Cryptography 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. Dates are, frankly, inordinately messy in OBIEE. If the database object has the Virtual Private Database option selected, the Oracle BI Server matches a list of security-sensitive variables to each prospective cache hit. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. Used for Oracle BI Server. Graph Css Data Type You can use a variable to specify the names of catalog and schema objects. Holds the name of the proxy user.

Used to enable or disable Oracle BI Server plan cache hits. Holds the Oracle BI Presentation Services user interface display language. The names of system session variables are reserved and cannot be used for other types of variables. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. This variable has a possible value of 0 or 1.
