By default, the first connection pool under the database object in the Physical layer is not available for selection. ), #business-intelligence-suite-enterprise-edition-obiee. 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 can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. The initialization block is a predecessor to another initialization block which does not have the Allow deferred execution option selected. 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 Data Filters tab, create the data filter expression: Note that the Expression Builder, as shown in the image that follows, displays only the multi-source session variable MVCOUNTRY, and not the regular session variables that were used during the creation of the multi-source session variable. It is also saved as the author field for catalog objects. Failure to execute can occur if the wrong credentials have been defined in the initialization block, or if there is an error in the default initialization string. See Creating Initialization Blocks for more information. It's why you can't see in the session manager a new value for the session.

You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. It is also saved as the author field for catalog objects. Create a dashboard prompt with the following characteristics : Select only the column Calendar.Calendar Year. When filtering cache table matches, the Oracle BI Server looks at the parent database object of each column or table that is referenced in the logical request projection list. When you have create a server variable, you have to reference it. 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. This allows the select statement to focus on just the data you want, rather than creating a view with potentially millions of rows and then subsequently applying a filter to that result set. Distance For session variable initialization blocks, you can select Row-wise initialization. Contains the locale of the user, typically populated from the LDAP profile of the user. 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 chapter contains the following topics: Working with Multi-Source Session Variables. There seems to be a glitch in the way obiee (11.1.1.6.0) interprets server variables when using them as default values for a dashboard prompt: only when the variable name is in uppercase and contains no underscores will it be recognised. In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. If the administrator user (defined upon install) has a Logging level defined as 4 and the session variable LOGLEVEL defined in the repository has a value of 0 (zero), the value of 0 applies. Collection It seems that OBIEE save the default initializer value in the same space than for a repository variable. Tree Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". See "About Connection Pools for Initialization Blocks" for more information.
