This is another system variable whose presence is always assumed when the USER system session variable is used. Variables should be used as arguments of the function VALUEOF(). For example, the following CASE statement is identical to the one explained in the preceding example, except that variables have been substituted for the constants: You cannot use variables to represent columns or other repository objects. Contains the locale of the user, typically populated from the LDAP profile of the user. Execution of session variable initialization blocks cannot be deferred in some circumstances. If you can get to set a number request variable because it always add quotes, it's a bug because the value is independent from the data type of your presentation variable (works for the version 10.3.4.1). 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). 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. Operating System Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. The Results dialog lists the variables and their values. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. In addition, if an initialization block fails for a particular connection pool during Oracle BI Server start-up, no more initialization blocks using that connection pool are processed. For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. Data (State) Because of this, if your repository has been upgraded from a previous release, you may see warnings in the Consistency Checker similar to the following: If you see warnings similar to this, update the relevant static repository variables so that the default initializers have constant values. To enable or disable an initialization block: In the Administration Tool, select Manage, then select Variables. 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. In the Session Variable dialog, type a variable name. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. For information about using session variables when setting up security, see "Managing Session Variables" in Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Repository variables can be used instead of literals or constants in Expression Builder in the Administration Tool. Color About Using Initialization Blocks with Variables, Associating Variables with Initialization Blocks, When Execution of Session Variable Initialization Blocks Cannot Be Deferred, Enabling and Disabling Initialization Blocks. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. For example, you have Color When you have create a server variable, you have to reference it. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. The tables do not have to be included in the Physical layer of the metadata. This system session variable overrides a variable defined in the Users object in the Administration Tool. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Server. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION.
