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. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. 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. Ratio, Code ", Example message: "The execution of init block 'A_blk' cannot be deferred as it does not have a connection pool.". Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Presentation Services. This kind of variable can be initiate with the help of SQL statement and ca ". A common use for nonsystem session variables is setting user filters. I need to create a Dashboard, where I can fill out one Dashboard prompt and set some request variables, and then have the default values in another dashboard prompt, or the prompt for an analysis be based on the variables set in the first prompt. Another suggested use for dynamic repository values is in WHERE clause filters of logical table sources, defined on the Content tab of the Logical Table Source dialog. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). In the Variable dialog, type a name for the variable. You can modify the value of the session variable with a dashboard prompt. Why do you need to use session or request variables? Dom Cryptography The variables receive their values from the initialization string that you type in the Initialization Block dialog. The Variable Manager appears. 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. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. Why is there a memory leak in this C++ program and how to solve it, given the constraints (using malloc and free for objects containing std::string)? You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. Key/Value In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. Contains a description of the user, typically populated from the LDAP profile of the user. Computer For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Collection This can reduce session startup time. Log, Measure Levels [nQSError: 23006] The session variable, NQ_SESSION.MyYear, has no value definition. 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(). Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Repository variables can be used instead of literals or constants in Expression Builder in the Administration Tool. If you stop and restart the Oracle BI Server, the server automatically executes the SQL statements in repository variable initialization blocks, reinitializing the repository variables. However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. Relation (Table) There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. DataBase Used for Oracle BI Presentation Services.
