For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Assume today is June 10. Execution of session variable initialization blocks cannot be deferred in some circumstances. Number There are two types of session variables: system and nonsystem. These multi-source session variables can be used in logical queries or in repository data filters, and contain the union of values from the different data sources. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower).

Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. The S of Server must be in uppercase. Close the Variable Manager and save the repository. The Oracle BI Server logs all SQL queries issued to retrieve session variable information if the logging level is set to 2 or higher in the Identity Manager User object, or the LOGLEVEL system session variable is set to 2 or higher in the Variable Manager. 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 system session variable overrides a variable defined in the Users object in the Administration Tool. Data Partition Select the type of variable: Static or Dynamic. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? Contains the groups to which the user belongs. If every new session needs the most current set of session variables and their corresponding values, you should clear this option. I am confused on how to use the non-system session variable in Answers, says, in column formula, in a filter and in title view. This variable has a possible value of 0 or 1. Dom In Expression Builder, click the Repository Variables folder in the left pane to display all repository variables (both static and dynamic) in the middle pane by name. This chapter describes how to use variables in the Oracle BI repository to streamline administrative tasks and dynamically modify metadata content to adjust to a changing data environment. Don't forget the quotes which enclose the Variable Name. Session variables are created and assigned a value when each user logs on. If the SQL statement contains an error, the database returns an error message. If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. The LDAP server name and the associated domain identifier appear in the Name and Domain identifier columns. Click here to get started. In the Session Variable dialog, type a variable name. OAuth, Contact To add a Default initializer value, type the value in the Default initializer box, or click the Expression Builder button to use Expression Builder. For repository variable initialization blocks, when you open a repository in online mode, the value shown in the Default initialization string field of the Initialization Block dialog is the current value of that variable as known to the Oracle BI Server. This system session variable overrides a variable defined in the Users object in the Administration Tool. To test initialization blocks (optional): In the Variable Manager dialog, double-click the initialization block. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements (for example, figures such as GIF files). 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)?

Lexical Parser It's why you can't see in the session manager a new value for the session. Logical Data Modeling From the Data Source Type list, select one of the following types. WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. Any legal SQL can be executed using an initialization block, including SQL that writes to the database or alters database structures, assuming the database permits the user ID associated with the connection pool to perform these actions. New to My Oracle Support Community? Security If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. In the right pane, select the Application Roles tab, then double-click the application role for which you want to set data filters.
