If any of the row-wise initialization blocks returns null results, this is logged in the Oracle BI Server log, nqserver.log. 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. The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Spatial Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Used for Oracle BI Presentation Services. When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. Process To create a new initialization block, click New. Web Services Text Note that the recommended practice is to use application roles rather than Catalog groups. Testing The second case is where a session variable needs to be evaluated as a string. In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. There are two types of session variables: system and nonsystem. When you select the Use OBI EE Server option, there is no need for a connection pool, because the SQL statement is sent to the Oracle BI Server and not directly to the underlying database. 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. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons,for example, RoleA;RoleB;RoleC. This variable has a possible value of 0 or 1. Javascript The values of session variables are established when a user logs in to OBIEE, and the same session variable may have a different value for each user. The values remain unchanged for the duration of the session. Used to enable or disable Oracle BI Server plan cache hits. You do not need to set up the PASSWORD variable, and you can use this variable in a database connection pool to allow passthrough login using the user ID and password of the user. For example, suppose a repository has two initialization blocks, A and B. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). You schedule these queries to be executed by the Oracle BI Server. variables is good where variable is bad. Click Link to associate an existing variable with an initialization block. Web Services Kurt Wolff, This variable is typically populated from the LDAP profile of the user. If you select Database as the data source type for an initialization block, the values returned by the database for the columns in your SQL statement are assigned to variables that you associate with the initialization block. All associated variables of the initialization block and its unexecuted predecessors are updated with the values returned from the deferred execution. This variable has a possible value of 0 or 1. Collection You can now use the multi-source session variable MVCOUNTRY in a logical query. When Jane connects to the Oracle BI Server, her session contains three session variables from row-wise initialization: LEVEL, containing the value 8; STATUS, containing the value FULL-TIME; and GRADE, containing the value AAA. When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. This is another system variable whose presence is always assumed when the USER system session variable is used. Assume today is June 10. Otherwise, a default initialization SQL string is used. To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). Data Visualization The format for the session variable names must be: where the separator must be exactly four underscore characters. See "Creating Initialization Blocks" for more information. You cannot use variables to represent columns or other repository objects. For example, the format of a date report variable can vary, depending on whether the user has changed the default value set by a dashboard calendar prompt. This variable has a possible value of 0 or 1. You can overtype this string. For Initialization Block, select mvcountry_sebl_init.

For example, if you have weeks that end on Saturday, you might want to have the date of the most recent Saturday in a session variable, called perhaps PREVIOUSSATURDAY. I have tried using the Variable Expression option to set the default values in the prompts, but it only uses the values of the session variables, not the temporary values in the request variables. Table 19-2 Sample Session Variables Database Table. This variable has a possible value of 0 or 1. In the right pane, select the Application Roles tab, then double-click the application role for which you want to set data filters. 2. Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. The next step is to establish execution precedence. OBIEE - Where can I use a BI Server variable (session/repository) ? In the following example, the session variable RETAILERID has been assigned a numeric value. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. Using the Multi-Source Session Variable in a Logical Query. 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. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). But when User B logs in he sees below error , when running the same report, [nQSError: 23006] The session variable, NQ_SESSION.PRODUCT, has no value definition. The Variable Manager dialog has two panes. 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. Database: For repository and session variables. If you initialize a variable using a character string, enclose the string in single quotes ( ' ). Nqgenoldverrpd Nqsconfig.ini Obi Server Variable Find Value Obiee And Olap Obiee Bridge Table Obiee Excel Importation Obiee Limit Clause Obiee Many To One Obiee Null Odbc Client Odbc Driver Bi Server Create Odbc Driver Bi Server Odbc Function Odbc Opaque View Ora 00937 Parameters Perf Prefer Internal Stitch Join Permission Persist Connection Pool This variable has a possible value of 0 or 1. File System How to get the closed form solution from DSolve[]? This option prevents execution of all session variable initialization blocks during the session logon stage, giving a shorter logon time. 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. StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. Security This value persists, and does not change until an administrator decides to change it. In the [Repository|Session] Variable Initialization Block dialog, click Edit Execution Precedence. Only repository variables can be used in the definition. This variable has a possible value of 0 or 1. Names for all variables should be unique. In the [Repository|Session] Variable Initialization Block Variable Target dialog, perform one of the following steps: Associate variables with the initialization block by doing one of the following: Click New, and in the Variable dialog, create a new variable. For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. Infra As Code, Web You can then use the SQL IN operator to test for values in a specified list. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. [emailprotected] Is there a limit on number of values session variable can hold. To remove a variable from association with this block, select the variable and click Remove. Graph OAuth, Contact Dynamic repository values can be set up to do it automatically. Logical Data Modeling Computer If you stop and restart the Oracle BI Server, the server automatically executes the SQL statement in the repository variable initialization blocks, re-initializing the repository variables. OBIEE - BI Server Variables (session and repository). To accurately reflect the new content of the recent source, you would have to modify the fragmentation content description manually. 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. Used to enable or disable Oracle BI Server result cache seeding. Relation (Table) Blog, KPI Partners provides strategic guidance and technology systems for clients wishing to solve complex business challenges involving cloud applications and big data.Learn more, Oracle | Tableau | Snowflake | AWS | Azure | ConfluentQlik | MapR | Cloudera | Hortonworks | DataStax | SAPTeradata | NetSuite | Salesforce | Attunity | Denodo |NumerifyView all, KPI Partners, Inc.39899 Balentine Drive, Suite #212, Using OBIEE Session Variables in Select Tables in the Physical Layer, BigQuery to optimize cost and performance, Data Lake Challenges with Databricks Delta Lake, Manual performance optimization in Denodo, Real-Time Supply Chain and Inventory Analytics, Snowflake secure views vs views in Oracle, traditional software development methodology. Relational Modeling 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. Design Pattern, Infrastructure This system session variable overrides a variable defined in the Users object in the Administration Tool. The Oracle BI Server can also provide functions (such as PI) that might not be available in the data source, and the SQL statement will work with other data sources supported by the Oracle BI Server (for example, ADF, SQL Server, Oracle, and XML files). This is another system variable whose presence is always assumed when the USER system session variable is used. When the execution of session variable initialization blocks cannot be deferred, a message is displayed that explains why. SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), #business-intelligence-suite-enterprise-edition-obiee. If you select this option, execution of the initialization block is deferred until an associated session variable is accessed for the first time during the session. You do not need to set up the PASSWORD variable, and you can use this variable in a database connection pool to allow passthrough login using the user ID and password of the user. In the Variable Manager dialog, select Action > New > Session > Variable. In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. The S of Server must be in uppercase. Logical Data Modeling While the component session variables appear in the Variable Manager, the multi-source session variable that has been created, MVCOUNTRY, will appear in Expression Builder. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. See "About Connection Pools for Initialization Blocks" for more information. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). [nQSError: 23006] The session variable, NQ_SESSION.MyYear, has no value definition. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. If you selected Database for your data source type, perform one of the following steps: Select Default initialization string or Use database specific SQL, and then perform the following steps: Click Browse next to the Connection Pool field to select the connection pool associated with the database where the target information is located. Testing Exists only for compatibility with previous releases. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Choose Enable or Disable from the right-click menu. There are two "flavors" of system variables: System session variables: User ID, the user's data security groups, and the user's web catalog group(s) are all examples of system . Does Cast a Spell make you a spellcaster? The value of LOGLEVEL, a number between 0 and 5, determines the logging level that the Oracle BI Server uses for user queries. The Oracle BI Server uses the cached results for subsequent sessions. Dynamic repository variables are useful for defining the content of logical table sources. See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. The LDAP server name and the associated domain identifier appear in the Name and Domain identifier columns. Data (State) Note: The Test button is disabled when the Use OBI EE Server option is selected in offline mode. To test initialization blocks (optional): In the Variable Manager dialog, double-click the initialization block. You also set up a schedule that the Oracle BI Server will follow to execute the query and periodically refresh the value of the variable. And when i try a system session variable VALUEOF(NQ_SESSION. Oracle BI, Execution of session variable initialization blocks cannot be deferred in some circumstances. GUIDs for application roles are the same as the application role names. Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". Mathematics Table 19-2 shows the table in this example. Holds the Oracle BI Presentation Services user interface display language. This section contains the following initialization string examples: Example 19-1, "A SQL Statement When Site Uses Delivers", Example 19-2, "A SQL Statement When Site Does Not Use Delivers", Example 19-3, "A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting", Example 19-1 A SQL Statement When Site Uses Delivers. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? 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. 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). See "About Using Initialization Blocks with Variables" for more information. Discrete The third case, dates, is the hardest. Users can select a language on the sign-in page for Oracle BI EE, or they can change the language setting on the Preferences tab of the My Account dialog after signing in. COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . When you create SQL and submit it directly to the database (for example, when using database-specific SQL in initialization blocks), the SQL statement bypasses the Oracle BI Server. 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.
