Session variables are created and assigned a value when each user logs on. Contains a description of the user, typically populated from the LDAP profile of the user. Data Structure However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. 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. Dynamic repository values can be set up to do it automatically. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. Expression Builder pastes it into the expression at the active cursor insertion point. You could then set a security filter for all members of a group that would allow them to view only data pertinent to their region.

You can change this behavior so that the first connection pool is available for selection by selecting Allow first Connection Pool for Init Blocks in the Options dialog, although this is not recommended. Shipping StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. Not the answer you're looking for? Note that this requirement is waived for internal processes (like Delivers) that use impersonation, if a single user session variable has been associated with the initialization block. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. Text In the right pane, right-click the initialization block you want to enable or disable. Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. Compiler For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. SELECT 'VALUEOF(NQ_SESSION.WEBLANGUAGE)' FROM DUAL I have set up a session variable initialization block to read in the variable names and values from my translated strings table with this SQL: select session_variable,translation from W_LOCALIZED_STRING_G where lang_id='VALUEOF(NQ_SESSION.LOCALE)' Nominal 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. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. This variable has a value of Yes. Css You can now use the multi-source session variable MVCOUNTRY in a logical query. It's meant to be a constant value. Why do you need to use session or request variables? The string you enter here is processed by the Oracle BI Server, and therefore as long as it is supported by the Oracle BI Server, the string will work with different data sources. The third case, dates, is the hardest. You cannot use any other value or expression as the default initializer for a static repository variable. Web Services In the Identity Manager dialog, in the tree pane, select BI Repository. This section provides information about working with session variables, and contains the following topics: Session variables are similar to dynamic repository variables in that they obtain their values from initialization blocks.

(The NQ_SYSTEM initialization block name is reserved.). The default location for the nqquery.log file is: You can use the row-wise initialization option to create session variables dynamically and set their values when a session begins. separate catalog. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. The initialization block is a predecessor to another initialization block which does not have the Allow deferred execution option selected. Url Key/Value Logical Data Modeling rev2023.3.1.43269. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. Since you are going to be setting these date variables using physical SQL in initialization blocks, the SQL issued will be specific to the database platform you are using. However, the cached results might not contain the most current session variable values. In the Application Role dialog, click Permissions. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. Dimensional Modeling Session variables that are not needed during the session do not have their initialization blocks executed. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements, for example, figures such as GIF files. The Oracle BI Server logs all SQL queries issued to retrieve repository variable information in nqquery.log when the logging level for the administrator account (set upon installation) is set to 2 or higher. For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. You must select a connection pool before typing an initialization string. Note: The Allow deferred execution option is unavailable in some circumstances. If a semicolon must be included as part of a Catalog group name, precede the semicolon with a backslash character (\). This is another system variable whose presence is always assumed when the USER system session variable is used. It is also saved as the author field for catalog objects. Used to enable or disable Oracle BI Server result cache seeding. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. The multi-source session variable will fail only if all of the component initialization blocks return null values. You can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. If you select Row-wise initialization, the Use caching option becomes available. If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). Asking for help, clarification, or responding to other answers. Versioning Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. Statistics For Oracle, you could write: trunc(sysdate) - to_char(sysdate,'D')+1 CurrentSunday, , trunc(sysdate) - to_char(sysdate,'D')+2 CurrentMonday, , trunc(sysdate) - to_char(sysdate, 'D')+7 CurrentSaturday, , trunc(sysdate) - to_char(sysdate,'D')+8 NextSunday, , trunc(sysdate) - to_char(sysdate,'D') PreviousSaturday, , trunc(sysdate) - to_char(sysdate,'D')+2-8 PreviousSunday, , trunc(sysdate) - to_char(sysdate,'D')+2-7 PreviousMonday, , cast(to_char(trunc(sysdate), 'YYYY') as INT) CurrentYear, , Cast(to_char(trunc(sysdate), 'YYYY')-1 as INT) PreviousYear, , add_months(trunc(last_day(sysdate)),-1) + 1 CurrentMonthFirstDay, , last_day(trunc(sysdate)) CurrentMonthLastDay, , add_months(TRUNC(last_day(sysdate)),-2) + 1 PreviousMonthFirstDay, , case when last_day(SYSDATE) = SYSDATE then TRUNC(SYSDATE) else add_months(TRUNC(last_day(sysdate)),-1) end LASTDAYCOMPLETEMONTH. This value persists, and does not change until an administrator decides to change it. Ratio, Code It is also saved as the author field for catalog objects. 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. See "About Row-Wise Initialization" for more information. Repository variables and system and nonsystem session variables are represented by a question mark icon. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. biServer is good where biserver is not good. Privacy Policy Used to enable or disable Oracle BI Server result cache hits. 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. Variables should be used as arguments of the function VALUEOF(). You can get this warning when you perform a check global consistency. This variable has a possible value of 0 or 1. For example, an initialization block might use the function pi(), which is specific to SQL Server. In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. The icon for an initialization block is a cube labeled i. Data (State) Then, in the Browse dialog, select the variable to be refreshed by this initialization block and click OK. For the Custom Authenticator data source type (Session variables only), the variable USER is required. Nominal Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. Design Pattern, Infrastructure Grammar In offline mode, the Set values for variables dialog is displayed so that you can populate :USER and :PASSWORD. By using OBIEE variables and a custom control table in Snowflake, we can achieve the same functionality without having to continuously make metadata updates or worry about the number of connection pools becoming a maintenance nightmare. Cause had logged in as admin and i got back the value (get back number: 2) as I expected In the start_level column of the business layer i used the following script as source: INDEXCOL( VALUEOF(NQ_SESSION . Log, Measure Levels With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. Otherwise, the default initialization SQL for the database type is used.
