Ive done it this way. Data Quality OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. For example, the NQ_SYSTEM initialization block is used to refresh system session variables. variables is good where variable is bad. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. For session variables, you can select the following options: Initialization Strings Used in Variables to Override Selection Steps. By default, when you open the Initialization Block dialog for editing in online mode, the initialization block object is automatically checked out. This is another system variable whose presence is always assumed when the USER system session variable is used. You can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. And when i try a system session variable VALUEOF(NQ_SESSION. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. The repository variable, NQ_SESSION.MyYear, has no value definition. OBIEE - BI Server Variables (session and repository). If there are fewer variables than columns, extra column values are ignored. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. Data Quality You can use a variable to specify the names of catalog and schema objects. The names of system session variables are reserved and cannot be used for other types of variables. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. Thanks for contributing an answer to Stack Overflow! The third case, dates, is the hardest. The value of LOGLEVEL, a number between 0 and 5, determines the logging level that the Oracle BI Server uses for user queries. In the Application Role dialog, click Permissions. Data Type variables is plural. For session variable initialization blocks, you can select Row-wise initialization. When you use these variables for Oracle BI Server, preface their names with NQ_SESSION. Oracle BI, This variable has a possible value of 0 or 1. For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. Http See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The names of system session variables are reserved and cannot be used for other types of variables. ), #business-intelligence-suite-enterprise-edition-obiee. For example, suppose you have two sources for information about orders. Monitoring If a semicolon must be included as part of a Catalog group name, precede the semicolon with a backslash character (\). In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. If you selected LDAP Server for your data source type, perform the following steps: Click Browse to select an existing LDAP Server, or click New to open the General tab of the LDAP Server dialog and create an LDAP Server. COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . You can also use this variable in a SQL statement. This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. In the right pane, select the Application Roles tab, then double-click the application role for which you want to set data filters. Automata, Data Type Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Variables should be used as arguments of the function VALUEOF(). When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. 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. Why is the error occurring only for User B? It's meant to be a constant value. Legacy groups are mapped to application roles automatically. Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. The SQL statement you use to refresh the variable might be written for a specific database. This variable is typically populated from the LDAP profile of the user. Statistics 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. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. Time Does Cast a Spell make you a spellcaster? For session variables, you can select the following options: Enable any user to set the value. Collection Html User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. 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. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". Computer The S of Server must be in uppercase. OBIEE - Where can I use a BI Server variable (session/repository) ? In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. Css You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. Testing A common use for nonsystem session variables is setting user filters. You can now use the multi-source session variable MVCOUNTRY in a logical query. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Presentation Services. For example, suppose a repository has two initialization blocks, A and B. Versioning You can find the nqquery.log file in: For more information about user-level logging, see "Managing the Query Log" in Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. Debugging In the following example, the session variable RETAILERID has been assigned a numeric value. Table 19-2 shows the table in this example. The icon for an initialization block is a cube labeled i. 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. If you do not want this to occur, use the Undo Check Out option. Network 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. Therefore, when you associate variables with an initialization block, the value returned in the first column is assigned to the first variable in the list. See "Testing Initialization Blocks" for more information. Scripting on this page enhances content navigation, but does not change the content in any way. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. Data Processing Data Warehouse Data Concurrency, Data Science If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. For example, you have NQ_SESSION.ROLES is a session variable that returns a semicolon delimited string of roles assigned to the . When you select the Use OBI EE Server option for an initialization block: Execution precedence does not apply, because during user login, an initialization block with the Use OBI EE Server option selected is executed after initialization blocks with the Use OBI EE Server option not selected. The value is case-insensitive. If you select this option, this initialization block must succeed for users to log in. You can't use SQL to set your default initializer, that's why you only see Constants as an option. a fiscal calendar) that you have stored in a Periods table, you can write the analogous SQL for that calendar. Exists only for compatibility with previous releases. 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). The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). Is there a limit on number of values session variable can hold. vegan) just to try it, does this inconvenience the caterers and staff? See "About Connection Pools for Initialization Blocks" for more information. Required for authentication. Holds the name of the proxy user. Used for Oracle BI Presentation Services. Web Services Url Example 19-2 A SQL Statement When Site Does Not Use Delivers. Lexical Parser 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). Relation (Table) When a user belongs to multiple Catalog groups, include the Catalog group names in the same column, separated by semicolons (for example, WebgroupA;WebgroupB;WebgroupC). For example, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth. You can also use the row-wise initialization option to initialize a variable with a list of values. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements, for example, figures such as GIF files. After they are created, variables are available for use in Expression Builder. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. OBIEE - How and where can I set a Request variable (SET VARIABLE) ? Holds the Oracle BI Presentation Services user interface display language. 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. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Close the Variable Manager and save the repository. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. Choose Enable or Disable from the right-click menu. The first case is where a session variable has a numeric value. In the Variable Manager dialog, select Action > New > Session > Variable. The value is case-insensitive. used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. Click OK to return to the Initialization Block dialog. See "Assigning a Name and Schedule to Initialization Blocks" for more information. 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. 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. This allows the select statement to focus on just the data you want, rather than creating a view with potentially millions of rows and then subsequently applying a filter to that result set. Time Used to enable or disable Oracle BI Server plan cache hits. You cannot use variables to represent columns or other repository objects. This kind of variable can be initiate with the help of SQL statement and ca ". (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. 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)? Static repository variables must have default initializers that are either numeric or character values. GUIDs for application roles are the same as the application role names. Exists only for compatibility with previous releases. OBIEE - Where can I use a BI Server variable (session/repository) . Data Persistence You must select a connection pool before typing an initialization string. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. Compiler Process 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. "store number" = VALUEOF(NQ_SESSION. When you have create a server variable, you have to reference it. Trigonometry, Modeling Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. Distance 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. Select this option to set session variables after the initialization block has populated the value (at user login) by calling the ODBC stored procedure NQSSetSessionValue(). If the SQL statement contains an error, the database returns an error message. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. Truce of the burning tree -- how realistic? If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. In the body, insert detailed information, including Oracle product and version. Init block 'B_blk' does not have "Allowed deferred execution" flag set. When the user modifies the date range using the first calendar, the format of the first date changes. Monitoring Quick question, a colleague of mine was telling me that the session variable, NQ_SESSION.GROUP, only shows groups which are assigned at the presentation >> level (or passed in from LDAP or other data source) but it does not show any of the group assignments made within the RPD itself. Selector The Dynamic Name tab is not active unless at least one session variable is defined. was shown. If every new session needs the most current set of session variables and their corresponding values, you should clear this option. Data Processing This variable has a possible value of 0 or 1. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. This chapter contains the following topics: Working with Multi-Source Session Variables. To create a session variable: In the Administration Tool, select Manage, then select Variables. 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. When the execution of session variable initialization blocks cannot be deferred, a message is displayed that explains why. 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. See "About Using Initialization Blocks with Variables" for more information. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. rev2023.3.1.43269. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. 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. 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. Selector I have created variables with the same name using row vise initialization. This section provides information about working with session variables, and contains the following topics: Session variables obtain their values from initialization blocks.
