Browser Using the Multi-Source Session Variable in a Logical Query. Select this option to set session variables after the initialization block has populated the value (at user login) by calling the ODBC stored procedure NQSSetSessionValue(). You schedule these queries to be executed by the Oracle BI Server. CREATE TABLE OBIEE_PROXY_USER ( PROXYID VARCHAR2 (100) NOT NULL, TARGETID VARCHAR2 (100) NOT NULL, PROXYLEVEL VARCHAR2 (100) NOT NULL) Insert some data : Create Session Variables for Proxy Functionality (inside the repository) Modify the instanceconfig.xml File for Proxy Functionality Here comes the more tricky parts When you have create a server variable, you have to reference it.

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. Repository variables and system and nonsystem session variables are represented by a question mark icon. This can reduce session startup time. System session variables have reserved names that cannot be used for other kinds of variables such as static or dynamic repository variables and nonsystem session variables. You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). Why must a product of symmetric random variables be symmetric? The query returns data only if the user ID and password match values found in the specified table. In the Select Connection Pool dialog, select the connection pool and click Select. Allow deferred execution. This section provides information about working with session variables, and contains the following topics: Session variables are similar to dynamic repository variables in that they obtain their values from initialization blocks. If you select this option, this initialization block must succeed for users to log in. A common way to set up a request variable in order to set a session repository variable is to create a dashboard prompt. Discrete You can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. This variable has a possible value of 0 or 1. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. When you select the Use OBI EE Server option, there is no need for a connection pool, because the SQL statement is sent to the Oracle BI Server and not directly to the underlying database. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. All associated variables of the initialization block and its unexecuted predecessors are updated with the values returned from the deferred execution. Graph ", Example message: "The execution of init block 'A_blk' cannot be deferred as it does not have a connection pool.".

Function 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. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Data (State) If a semicolon must be included as part of a Catalog group name, precede the semicolon with a backslash character (\). You use the same procedure to define nonsystem session variables as for system session 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. The format for the session variable names must be: where the separator must be exactly four underscore characters. This variable has a value of Yes. In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. Nominal When a user belongs to multiple Catalog groups, include the Catalog group names in the same column, separated by semicolons (for example, WebgroupA;WebgroupB;WebgroupC). biServer is good where biserver is not good. In the right pane, select the Application Roles tab, then double-click the application role for which you want to set data filters. An error will generate if a session variable is used. In the Identity Manager dialog, in the tree pane, select BI Repository. Names for all variables should be unique. In the Administration Tool, select Manage, then select Variables. The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). 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). Example 19-3 A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting. In the Session Variable dialog, type a variable name. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. How can the mass of an unstable composite particle become complex? In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. Dom Required for authentication. A proxy user is a user that has been authorized to act for another user. See "About Using Initialization Blocks with Variables" for more information. See "About Row-Wise Initialization" for more information. Database: For repository and session variables. 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. This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. Then, you explicitly define session variables for each source. Selecting the Use caching option directs the Oracle BI Server to store the results of the query in a main memory cache. Select the type of variable: Static or Dynamic. Is Koestler's The Sleepwalkers still well regarded? 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. At run time, if an initialization string for the database type has been defined, this string is used. This kind of variable can be initiate with the help of SQL statement and ca ". select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. 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. Used for Oracle BI Presentation Services. The left pane displays a tree that shows variables and initialization blocks, and the right pane displays details of the item you select in the left pane. Names for all variables should be unique. For example, if you have weeks that end on Saturday, you might want to have the date of the most recent Saturday in a session variable, called perhaps PREVIOUSSATURDAY. This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. Data Warehouse The LDAP server name and the associated domain identifier appear in the Name and Domain identifier columns. WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). Create a second session variable called MVCOUNTRY____ORCL, making sure to include four underscores between the variable name and the source name. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. The query returns data only if the user ID and password match values found in the specified table. Http What are some tools or methods I can purchase to trace a water leak? (Session init blocks only) Select the following options when appropriate: Disabled.
