User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. Static repository variables must have default initializers that are constant values. File System Linear Algebra This variable has a possible value of 0 or 1. Web Services Used for Oracle BI Server. It's meant to be a constant value. 1. Relational Modeling Contains the locale of the user, typically populated from the LDAP profile of the user. Used for Oracle BI Presentation Services. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. In the Session Variable dialog, type a variable name. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. 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). For example, here are dates as set by the default values in the prompt. COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . Used for Oracle BI Presentation Services. The SQL statement used to refresh the variable must reference physical tables that can be accessed through the connection pool specified in the Connection Pool field. Url Click Link to associate an existing variable with an initialization block. Data Science You won't be able to use the Oracle date functions for many of the values you want, but you can still write the SQL to return the values according to the fiscal periods in your calendar using different methods. In the Session Variable dialog, type a variable name. Data Processing You can use a variable to specify the names of catalog and schema objects. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. In the right pane, right-click the initialization block you want to enable or disable. Identifies the query as a SELECT_PHYSICAL query. Data (State) This variable has a value of Yes. Contains the application roles to which the user belongs. This section explains how to create repository variables. 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. Then, you explicitly define session variables for each source. This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. Url For Initialization Block, select mvcountry_orcl_init. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. An error will generate if a session variable is used. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. Table 19-2 Sample Session Variables Database Table. The SQL statement you use to refresh the variable might be written for a specific database. Data Type Any legal SQL can be executed using an initialization block, including SQL that writes to the database or alters database structures, assuming the database permits the user ID associated with the connection pool to perform these actions. Text Spatial If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. Rather than entering the numbers 17 and 23 into this expression as constants, you could use the Variable tab of the Variable dialog to set up a static repository variable named prime_begin and initialize it to a value of 17, and create another variable named prime_end and initialize it to a value of 23. For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Server Presentation Service Installed On Two Machines. Function Debugging However, if you select Use OBI EE Server, the query is rewritten by the Oracle BI Server for the appropriate database. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. Oracle BI, Function Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. Holds the Oracle BI Presentation Services user interface display language. Identifies the query as a SELECT_PHYSICAL query. The following example illustrates how to create and use a multi-source session variable: In the Variable Manager in the Administration Tool, select Action > New > Session > Initialization Block. Choose Enable or Disable from the right-click menu. Exists only for compatibility with previous releases. For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. See "Examples of Initialization Strings" for additional examples. Using the Multi-Source Session Variable in a Logical Query. The order of the columns in the SQL statement and order of the variables associated with the initialization block determine the column value that is assigned to each variable. For example, suppose a repository has two initialization blocks, A and B. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. Create a row-wise initialization block called mvcountry_sebl_init with the following SQL for Default initialization string: Create a second row-wise initialization block called mvcountry_orcl_init with the following SQL for Default initialization string: Still in the Variable Manager, select Action > New > Session > Variable. Learn about session variables and how to create them. 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. This kind of variable can be initiate with the help of SQL statement and ca ". When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. This variable has a possible value of 0 or 1. See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. Data Warehouse 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. While the initialization block is checked out, the Oracle BI Server may continue to refresh the value of dynamic variables refreshed by this initialization block, depending on the refresh intervals that are set. 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. repository. In the User/Application Role Permissions dialog, click the Data Filters tab. Could anyone please advise? 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 initialization block is used by session variables where the Security Sensitive option is selected in the Session Variable dialog. For Example the report looks like this Region VALUEOF (REGION) SALES North Some value from North Variable 100 In order to create an OBIEE Analytics Agent, you have to connect to Oracle BI Analytics: This SQL statement contains two constraints in the WHERE clause: ':USER' (note the colon and the single quotes) is the ID the user types when logging in. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? In the [Repository|Session] Variable Initialization Block Data Source dialog, click Test. The values remain unchanged for the duration of the session. select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. Security Sensitive. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. Dimensional Modeling When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. This section explains how to create session variables. [nQSError: 23006] The session variable, NQ_SESSION.user, has no value definition. 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(). used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. Create a dashboard prompt with the following characteristics : Select only the column Calendar.Calendar Year. New to My Oracle Support Community? (HY000) SQL Issued: SET VARIABLE MYYEAR='1998';SELECT TIMES_VIEW.calendar_year saw_0 FROM Test ORDER BY saw_0 Try to use the same letter case for the name of the variable (upper and lower). For example, suppose you want to create an expression to group times of day into different day segments. Tags: Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. 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. Compiler For example, suppose you have two sources for information about orders. Used for Oracle BI Presentation Services. Key/Value So what *is* the Latin word for chocolate? Variables should be used as arguments of the function VALUEOF(). You need to describe the content of these sources on the Content tab of the Logical Table Source dialog. The next step is to select the data source and connection pool. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. 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. It seems that OBIEE save the default initializer value in the same space than for a repository variable. If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. Mathematics Data (State) Holds the value the user enters as his or her logon name. Html Then, enter its associated string. The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). For example, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth. See "Assigning a Name and Schedule to Initialization Blocks" for more information. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. Mathematics You would initialize a session variable named Client, for example, that could be Security The next step is to establish execution precedence. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. Javascript Used for Oracle BI Server. Security The new value is only valuable for the query. Data Partition Http data for multiple clients and you structured the database so that data for each client was in a As with dynamic repository variables, session variables obtain their values from initialization blocks.

Contains the groups to which the user belongs. 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. In the Variable Manager dialog, double-click the last initialization block that you want to be initialized. For example, the NQ_SYSTEM initialization block is used to refresh system session variables. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Specifies the Catalog groups (Presentation Services groups) to which the user belongs, if any. (Apart from the obvious answer: it's a bug. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. Is Koestler's The Sleepwalkers still well regarded? 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. To remove a variable from association with this block, select the variable and click Remove. The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. 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. Contains the time zone of the user, typically populated from the LDAP profile of the user. An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. This article show you with the help of the sh schema a little example. 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. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Does Cast a Spell make you a spellcaster? When a user belongs to multiple roles, include the role names in the same column, separated by semicolons,for example, RoleA;RoleB;RoleC. To add a Default initializer value, type the value in the Default initializer box, or click the Expression Builder button to use Expression Builder. Repository variables and system and nonsystem session variables are represented by a question mark icon. Data Structure If you use a SQL tool, be sure to use the same DSN or one set up identically to the DSN in the specified connection pool. Color To learn more, see our tips on writing great answers. The other two can not be addressed it seems, I have tried variations: The same goes for default selection type 'variable expression': the expected result is achieved when using @{biServer.variables['NQ_SESSION.STORENBR']}, yet no such luck using: @{biServer.variables['NQ_SESSION.SV_STORE_NBR']}, @{biServer.variables['NQ_SESSION. 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. Note that the recommended practice is to use application roles rather than Catalog groups. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). This chapter contains the following topics: Working with Multi-Source Session Variables. Scripting on this page enhances content navigation, but does not change the content in any way. 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. Testing To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Data Quality Nominal Cryptography WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. Legacy groups are mapped to application roles automatically. The repository variable, NQ_SESSION.MyYear, has no value definition. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). Assume today is June 10. 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. All associated variables of the initialization block and its unexecuted predecessors are updated with the values returned from the deferred execution. Grammar This happens automatically when you double-click the variables to paste them into the expression. Dom 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. Log, Measure Levels See "About Connection Pools for Initialization Blocks" for more information. Shipping The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services.

Design Pattern, Infrastructure BETWEEN case when substr('valueof(NQ_SESSION. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. Data (State) Relation (Table) However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. File System You use the same procedure to define nonsystem session variables as for system session variables. Process (Thread) If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. You can also right-click an existing initialization block in the Variable Manager and choose Disable or Enable. The first case is where a session variable has a numeric value. Business Intelligence Server Enterprise Edition - Version 11.1.1.6.12 and later: OBIEE 11g: Error: "[nQSError: 23006] The session variable, NQ_SESSION.ICX_SESSION_CO Database: For repository and session variables. Click Edit Data Source next to the Connection Pool field. Dynamic repository values can be set up to do it automatically. The USER value always matches the PROXY variable, that is the act as value. Graph Why is the error occurring only for User B? StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. Collection 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. After they are created, variables are available for use in Expression Builder. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Required for authentication. Contains the groups to which the user belongs. If you selected Custom Authenticator for your data source type, perform the following steps: Click Browse to select an existing custom authenticator, or click New to create one. In the Variable dialog, type a name for the variable. Use the Initialization Block list to select an initialization block that will be used to refresh the value on a continuing basis. Is there a reason you can't use user variable? Holds the Oracle BI Presentation Services user interface display language. Custom Authenticator: For session variables. OBIEE - Where can I use a BI Server variable (session/repository) .

The tables do not have to be included in the Physical layer of the metadata. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. If the SQL statement contains an error, the database returns an error message. Contains the time zone of the user, typically populated from the LDAP profile of the user. 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. You can edit repository initialization blocks, or session initialization blocks. Used for Oracle BI Presentation Services. Failure to execute can occur if the wrong credentials have been defined in the initialization block, or if there is an error in the default initialization string. I have created variables with the same name using row vise initialization. Testing If you select this option, the initialization block is disabled. Used to enable or disable Oracle BI Server plan cache hits. You schedule these queries to be executed by the Oracle BI Server. 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. The S of Server must be in uppercase. For example, you have For example, this option lets non-administrators to set this variable for sampling. 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. Click OK to return to the Initialization Block dialog. The intent is to filter that data just for that retailer. Infra As Code, Web OAuth, Contact Linear Algebra 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. There are two types of session variables: system and nonsystem. Tree 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). To use a repository variable in an expression, select it and double-click. Is there a limit on number of values session variable can hold. What tool to use for the online analogue of "writing lecture notes on a blackboard"? 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 (). The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements, for example, figures such as GIF files. In other words, if you change the SQL Server back-end database to Oracle, the query will still work. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. Graph Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. "store number" = VALUEOF(NQ_SESSION. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. OBIEE - BI Server Variables (session and repository). The value is case-insensitive. 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. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. (The NQ_SYSTEM initialization block name is reserved.). Otherwise, a default initialization SQL string is used. For static repository variables, the value you specify in the Default initializer window persists. Ratio, Code OBIEE - How and where can I set a Request variable (SET VARIABLE) ? The Variable Manager dialog has two panes. In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. This system session variable overrides a variable defined in the Users object in the Administration Tool. Versioning Order Javascript From the Data Source Type list, select one of the following types. Table 19-1 describes the available system session variables. 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. The query returns data only if the user ID and password match values found in the specified table. Color This variable is typically populated from the LDAP profile of the user. 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. See "About Row-Wise Initialization" for more information. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. How can the mass of an unstable composite particle become complex? If you select this option, this initialization block must succeed for users to log in. This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables and removing the NQS_PASSWORD_CLAUSE clause. Legacy groups are mapped to application roles automatically. Used for Oracle BI Presentation Services. Based on products assigned to user in security table, data filter is applied. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them.
