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. Launching the CI/CD and R Collectives and community editing features for OBIEE 12C: dashboard prompt auto fill when selection is sql result, dashboard prompt doesn't work in obiee 11g when using javascript, Oracle gives error Message on prompt refresh, OBIEE 11 - How to export a multipage dashboard in excel without prompt, Using table function in OBIEE RPD (physical layer) and pass parameter from dashboard prompt to it, obiee12c dashboard prompts running before analysis filters. Data (State) You can use the Variable Manager in the Administration Tool to define variables. See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. This system session variable overrides a variable defined in the Users object in the Administration Tool. (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). See "Creating Initialization Blocks" for more information. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. 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. Logical Data Modeling Each instance of a session variable could be initialized to a different value. This is another system variable whose presence is always assumed when the USER system session variable is used. Data Analysis You can also use this variable in a SQL statement. Data (State) In the User/Application Role Permissions dialog, click the Data Filters tab. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The multi-source session variable will fail only if all of the component initialization blocks return null values. 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. You cannot use variables to represent columns or other repository objects. Close the Variable Manager and save the repository. If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). For this example, you would provide the following SQL statement for the initialization string: Note that NQ_SESSION.USERID has already been initialized using another initialization block. . Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. Data Persistence See "Examples of Initialization Strings" for additional examples. (Optional) Click Test to test the data source connectivity for the SQL statement. This variable is typically populated from the LDAP profile of the user. Data Type However, if you select Use OBI EE Server, the query is rewritten by the Oracle BI Server for the appropriate database. Select the type of variable: Static or Dynamic. You can also use the row-wise initialization option to initialize a variable with a list of values. Then, you explicitly define session variables for each source. OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. Color 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. Exists only for compatibility with previous releases. If there are fewer variables than columns, extra column values are ignored. Url You use the same procedure to define nonsystem session variables as for system session variables. 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. WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). To test initialization blocks (optional): In the Variable Manager dialog, double-click the initialization block. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables. 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. Contains the groups to which the user belongs. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. Based on products assigned to user in security table, data filter is applied. In the [Repository|Session] Variable Initialization Block dialog, click Edit Execution Precedence. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. For Initialization Block, select mvcountry_sebl_init. Dynamic repository variables are useful for defining the content of logical table sources. In other words, if you change the SQL Server back-end database to Oracle, the query will still work. Number Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. 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. Execution of session variable initialization blocks cannot be deferred in some circumstances. See "About Row-Wise Initialization" for more information. Design Pattern, Infrastructure The Dynamic Name tab is not active unless at least one session variable is defined. Selecting the Use caching option directs the Oracle BI Server to store the results of the query in a main memory cache. For static repository variables, the value you specify in the Default initializer window persists. For example, the NQ_SYSTEM initialization block is used to refresh system session variables. A proxy user is a user that has been authorized to act for another user. For example, I have declared and initialised 3 server variables: All 3 contain a value after logging on, I verified this in the obiee admin tool 'manage sessions' screen. This section provides information about working with session variables, and contains the following topics: Session variables obtain their values from initialization blocks. Server Presentation Service Installed On Two Machines. Data Quality Contains the time zone of the user, typically populated from the LDAP profile of the user. This option prevents execution of all session variable initialization blocks during the session logon stage, giving a shorter logon time. The intent is to filter that data just for that retailer. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. 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. What are some tools or methods I can purchase to trace a water leak? Instead, the connection pool is blacklisted and subsequent initialization blocks for that connection pool are skipped. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. Computer Used for Oracle BI Presentation Services. So what *is* the Latin word for chocolate? Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. Example 19-2 A SQL Statement When Site Does Not Use Delivers. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. Determines if the initialization blocks required for authentication are executed. OBIEE - How and where can I set a Request variable (SET VARIABLE) ? When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. vegan) just to try it, does this inconvenience the caterers and staff? If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. It is also saved as the author field for catalog objects. If the administrator user (defined upon install) has a Logging level defined as 4 and the session variable LOGLEVEL defined in the repository has a value of 0 (zero), the value of 0 applies. In the Browse dialog, select the blocks that should be initialized before the block that you have open, and then click OK. To remove a block, in the [Repository|Session] Variable Initialization Block Execution Precedence dialog, select the block you want to remove and click Remove. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Graph OBIEE - How to set and use a server variable (system/repository) of type date ? select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. Is there any way to do this? Expression Builder pastes it into the expression at the active cursor insertion point. The LDAP server name and the associated domain identifier appear in the Name and Domain identifier columns. 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. rev2023.3.1.43269. In the Variable dialog, type a name for the variable. If you order a special airline meal (e.g. Click Link to associate an existing variable with an initialization block. 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). 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. [emailprotected] For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. Debugging 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(). When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). Status, to include it in a where clause of the content tab of a logical table source, to create a dashboard prompt to set up this session variable, and to test it on a little answer with only the year as column, click on the node : Session/Variables/Non System, and create a session variable MyYear with for instance this default initialization string for the oracle database, Set Variable : Request Variable and the value MyYear, Server Presentation Service Installed On Two Machines. 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. 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. Holds the name of the proxy user. variables is good where variable is bad. Each instance of a session variable could be initialized to a different value. OBIEE - Where can I use a BI Server variable (session/repository) . In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Trigonometry, Modeling was shown. 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. Does Cast a Spell make you a spellcaster? The initialization block is used by session variables named PROXY or USER. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. This variable has a possible value of 0 or 1. Only repository variables can be used in the definition. You can modify the value of the session variable with a dashboard prompt. Discrete For more information, see Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. It seems that OBIEE save the default initializer value in the same space than for a repository variable. used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. Distance 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. For example, an initialization block might use the function pi(), which is specific to SQL Server. Used for Oracle BI Server. The Oracle BI Server substitutes the value of the repository variable for the variable itself in the metadata. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. 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. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. Dynamic repository values can be set up to do it automatically. 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 . Lexical Parser 1. After they are created, variables are available for use in Expression Builder. The table contains three columns: USERID, containing values that represent the unique identifiers of the users, NAME, containing values that represent session variable names, VALUE, containing values that represent session variable values. Database: For repository and session variables. This logical WHERE clause expands into a physical IN clause, as shown in the following statement: See "About Using Initialization Blocks with Variables" for more information about initialization blocks. See "Examples of Initialization Strings" for examples. Enter a title that clearly identifies the subject of your question. In the Variable Manager dialog, select Action > New > Session > Variable. 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. If you do not want this to occur, use the Undo Check Out option. See Creating Initialization Blocks for more information. Thanks for contributing an answer to Stack Overflow! OBIEE - BI Server Patch (automatic update with a patch file) In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. In Expression Builder, click the Repository Variables folder in the left pane to display all repository variables (both static and dynamic) in the middle pane by name. I try to display the variable by define it in column formula as VALUEOF(NQ_SESSION. Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). 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. The table describes the available system session variables. If you selected Dynamic, use the Initialization Block list to select an existing initialization block that will be used to refresh the value on a continuing basis. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. The Oracle BI Server uses the cached results for subsequent sessions. Relational Modeling For example, suppose you want to create an expression to group times of day into different day segments. The SQL SELECT statement in the Default initializer list can contain multiple columns. A repository variable has a single value at any point in time. A proxy user is a user that has been authorized to act for another user. The initialization block is used to set your session variable to a dynamic value. The Results dialog lists the variables and their values. In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". Javascript https://docs.oracle.com/cd/E28280_01/bi.1111/e10540/variables.htm#BIEMG3104 Share Improve this answer Follow 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. (The NQ_SYSTEM initialization block name is reserved.). Process Contains the application roles to which the user belongs. Used for Oracle BI Server. The initialization block is a predecessor to another initialization block which does not have the Allow deferred execution option selected. Data Concurrency, Data Science 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. You can use a variable to specify the names of catalog and schema objects. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval.
