Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. When you select the Use OBI EE Server option for an initialization block: Execution precedence does not apply, because during user login, an initialization block with the Use OBI EE Server option selected is executed after initialization blocks with the Use OBI EE Server option not selected. The variables receive their values from the initialization string that you type in the Initialization Block dialog. Http This section explains how to create repository variables. In the [Repository|Session] Variable Initialization Block dialog, click Edit Execution Precedence.

The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. Session variables are created and assigned a value when each user logs on. Ratio, Code When the value of a dynamic repository variable changes, all cache entries associated with a business model that reference the value of that variable are purged automatically. For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr See "About Connection Pools for Initialization Blocks" for more information.
