Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Computer Example 19-2 A SQL Statement When Site Does Not Use Delivers. 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. Cube Holds the value the user enters as his or her logon name. In the [Repository|Session] Variable Initialization Block Data Source dialog, click Test. File System I try to display the variable by define it in column formula as VALUEOF (NQ_SESSION."ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." was shown. You can use the Variable Manager in the Administration Tool to enable and disable initialization blocks. For session variables, you can select the following options: Enable any user to set the value. In the Data Filters tab, create the data filter expression: Note that the Expression Builder, as shown in the image that follows, displays only the multi-source session variable MVCOUNTRY, and not the regular session variables that were used during the creation of the multi-source session variable. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. 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. System session variables are session variables that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes. See <> for more information. You can then use the SQL IN operator to test for values in a specified list. select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. If you initialize a variable using a character string, enclose the string in single quotes ( ' ). You cannot use variables to represent columns or other repository objects. The following session variables would be created: When John connects to the Oracle BI Server, his session contains two session variables from row-wise initialization: LEVEL, containing the value 4, and STATUS, containing the value FULL_TIME. Initializing Dynamic Repository Variables. Privacy Policy The following list summarizes the scenarios in which execution of session variable initialization blocks cannot be deferred: The Row-wise initialization option is selected in the Session Variable Initialization Block Variable Target dialog and the variables have not been declared explicitly with default values. 3. Lexical Parser In the Variable Manager dialog, select Action > New > Session > Variable. In the Session Variable dialog, type a variable name. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. If there are fewer variables than columns, extra column values are ignored. Anybody who knows or can guess the name of the variable can use it in an expression in Answers or in a Logical SQL query. Operating System SQL -SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), Data filter condition is set on the Fact & Dimension tables in the application role. The tables do not have to be included in the Physical layer of the metadata. To create a new initialization block, click New. 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. The Variable Manager dialog has two panes. When the value of a dynamic repository variable changes, all cache entries associated with a business model that reference the value of that variable are purged automatically. Each instance of a session variable could be initialized to a different value. See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. To view full details, sign in to My Oracle Support Community. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. Learn about session variables and how to create them.

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. (Apart from the obvious answer: it's a bug. This automatically creates a single multi-source session variable, named: The component session variable names (____) appear separately in the Variable Manager in the Administration Tool, but the Expression Builder displays only the single multi-source session variable name (). "ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." For example, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth. Time This variable has a possible value of 0 or 1. You open initialization block B, and then specify that block A will execute before block B. For example, suppose you want to create an expression to group times of day into different day segments. Otherwise, the default initialization SQL for the database type is used. DataBase "storenbr"), What am I missing? In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. In the right pane, select the Application Roles tab, then double-click the application role for which you want to set data filters. The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). [nQSError: 23006] The session variable, NQ_SESSION.user, has no value definition. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. Privacy Policy 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. Color Data Processing Linear Algebra If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). Used to enable or disable Oracle BI Server plan cache seeding. Data Type If the SQL statement contains an error, the database returns an error message. For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. This variable has a possible value of 0 or 1. 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. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. You must select a connection pool before typing an initialization string. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables. See "About Connection Pools for Initialization Blocks" for more information. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements, for example, figures such as GIF files. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. A common use of these variables is to set filters for use in Oracle BI Presentation Services. To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. variables is good where variable is bad. 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)? 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)' For example, you have Distance Business Intelligence Server Enterprise Edition - Version 12.2.1.0.0 to 12.2.1.4.200414 [Release 12g]: OBIEE 12c - case sensitivity of USER session variable name OBIEE 12c - case sensitivity of . Could anyone please advise? Mathematics Used to enable or disable Oracle BI Server result cache seeding. 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. OBIEE - BI Server Patch (automatic update with a patch file) This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. This system session variable overrides a variable defined in the Users object in the Administration Tool. I try to display the variable by define it in column formula as VALUEOF(NQ_SESSION. BETWEEN case when substr('valueof(NQ_SESSION. The order of the columns in the SQL statement and the order of the variables associated with the initialization block determine which columns are assigned to each variable. Logical Data Modeling In the body, insert detailed information, including Oracle product and version. Design Pattern, Infrastructure If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). Url This section explains how to create session variables. 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. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. To assign a name and schedule to initialization blocks: In the Variable Manager dialog, from the Action menu, choose New > Repository (or Session) > Initialization Block. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). GUIDs for application roles are the same as the application role names. User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. Mathematics Values in repository and session variables are not secure, because object permissions do not apply to variables. Data Visualization Css 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. Session variables that are not needed during the session do not have their initialization blocks executed. Data Partition From the Data Source Type list, select one of the following types. In addition to supporting regular session variables that are populated from one data source, Oracle Business Intelligence also supports session variables that can be populated from multiple data sources. As with dynamic repository variables, session variables obtain their values from initialization blocks. CREATE TABLE OBIEE_PROXY_USER ( PROXYID VARCHAR2 (100) NOT NULL, TARGETID VARCHAR2 (100) NOT NULL, PROXYLEVEL VARCHAR2 (100) NOT NULL) Insert some data : Create Session Variables for Proxy Functionality (inside the repository) Modify the instanceconfig.xml File for Proxy Functionality Here comes the more tricky parts Each query can refresh several variables: one variable for each column in the query. If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. Security In the Select Connection Pool dialog, select the connection pool and click Select. Text Contains the application roles to which the user belongs. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. In the Variable Manager dialog, select Action > New > Repository > Variable. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Process (Thread) If these date prompts are setting report variables, you need to be able to deal with both formats. Custom Authenticator: For session variables. StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. 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). In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. Note: The Test button is disabled when the Use OBI EE Server option is selected in offline mode. Select this option to identify the variable as sensitive to security when using a row-level database security strategy, such as a Virtual Private Database (VPD). Function Grammar Relation (Table) 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. 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. 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. I have created variables with the same name using row vise initialization. Data Concurrency, Data Science Data Persistence Discrete For Initialization Block, select mvcountry_orcl_init. If you select this option, the initialization block is disabled. Monitoring Create a dashboard prompt with the following characteristics : Select only the column Calendar.Calendar Year. 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. This is another system variable whose presence is always assumed when the USER system session variable is used. You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. You can only test this SQL statement using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog when in online mode. You can then use this variable in a filter, as shown in the following WHERE clause: The variable LIST_OF_USERS contains a list of values, that is, one or more values. Holds the Oracle BI Presentation Services user interface display language. Not the answer you're looking for? If every new session needs the most current set of session variables and their corresponding values, you should clear this option.
