Http Is there any way to do this? (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). Repository variables can be used instead of literals or constants in Expression Builder in the Administration Tool. The values remain unchanged for the duration of the session. GUIDs for application roles are the same as the application role names. Design Pattern, Infrastructure What tool to use for the online analogue of "writing lecture notes on a blackboard"? So what *is* the Latin word for chocolate? Function You can modify the value of the session variable with a dashboard prompt. This section provides information about working with session variables, and contains the following topics: Session variables are similar to dynamic repository variables in that they obtain their values from initialization blocks. Shipping To reorder variables, select a variable and click Up or Down. 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. Select a discussion category from the picklist. Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. If you select this option, the initialization block is disabled. In the following example, the session variable RETAILERID has been assigned a numeric value. If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. Log, Measure Levels Used to enable or disable Oracle BI Server subrequest cache hits and seeding. If the SQL statement contains an error, the database returns an error message. The initialization block is used to set your session variable to a dynamic value. Based on products assigned to user in security table, data filter is applied. 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. https://docs.oracle.com/cd/E28280_01/bi.1111/e10540/variables.htm#BIEMG3104 Share Improve this answer Follow See "Creating Initialization Blocks" for more information. 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. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. Discrete The format for the session variable names must be: where the separator must be exactly four underscore characters. Determines if the initialization blocks required for authentication are executed. Identifies the query as a SELECT_PHYSICAL query. Trigonometry, Modeling Enable any user to set the value. Could anyone please advise? For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. [nQSError: 23006] The session variable, NQ_SESSION.MyYear, has no value definition. It is also saved as the author field for catalog objects. You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). Is there a reason you can't use user variable? Note that the recommended practice is to use application roles rather than Catalog groups. The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. Grammar Data Processing "SV_STORE_NBR"']}, @{biServer.variables['NQ_SESSION.storenbr']}, @{biServer.variables['NQ_SESSION."storenbr"']}. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. The query returns data only if the user ID and password match values found in the specified table. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. Table 19-2 Sample Session Variables Database Table. Data Processing Dimensional Modeling To test initialization blocks (optional): In the Variable Manager dialog, double-click the initialization block. I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. When you have create a server variable, you have to reference it. Grammar The Oracle BI Server logs all SQL queries issued to retrieve repository variable information in nqquery.log when the logging level for the administrator account (set upon installation) is set to 2 or higher. Close the Variable Manager and save the repository. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. The USER value always matches the PROXY variable, that is the act as value. Relational Modeling Contains the groups to which the user belongs. For static repository variables, the value you specify in the Default initializer window persists. I need to create a Dashboard, where I can fill out one Dashboard prompt and set some request variables, and then have the default values in another dashboard prompt, or the prompt for an analysis be based on the variables set in the first prompt. Network You can call a server variable by using this syntax : Data (State) The left pane displays a tree that shows variables and initialization blocks, and the right pane displays details of the item you select in the left pane. Html In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. Does Cosmic Background radiation transmit heat? In other words, if you change the SQL Server back-end database to Oracle, the query will still work. It's meant to be a constant value. 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. See "About Using Initialization Blocks with Variables" for more information. 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. You can get this warning when you perform a check global consistency. 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. It would be nice if there was a single place where you could say Id like dates to be formatted like this. But there isnt (a huge oversight, in my opinion), and if you attempt to descend into the javascript code forest to tweak things well, good luck. An error will generate if a session variable is used. The Use caching option is automatically selected when you select the Row-wise initialization option. Used to enable or disable Oracle BI Server result cache hits. 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. Note: The Allow deferred execution option is unavailable in some circumstances. You open initialization block B, and then specify that block A will execute before block B. ), #business-intelligence-suite-enterprise-edition-obiee. Click here to get started. Execution of session variable initialization blocks cannot be deferred in some circumstances. Session variables that are not needed during the session do not have their initialization blocks executed. Text The NQ_SYSTEM initialization block name is reserved. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. This option prevents execution of all session variable initialization blocks during the session logon stage, giving a shorter logon time. 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 Number ':PASSWORD' (note the colon and single quotes) is the password the user enters. New to My Oracle Support Community? The syntax is: WHERE COMPANYID=ValueOf (NQ_SESSION.RETAILERID) The second case is where a session variable needs to be evaluated as a string. Data Partition To accurately reflect the new content of the recent source, you would have to modify the fragmentation content description manually. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. Statistics This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Server. As with dynamic repository variables, session variables obtain their values from initialization blocks. 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. Time Cryptography Graph Using the convention that weeks begin on Sunday (adjust accordingly if thats not the case for your enterprise), we can think of Current, Previous, and Next weeks. 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)? The obiee logical sql request doesn't contain any filter : The logical request doesn't contain any filter : But the final query, send in the database, contains one. 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. Used for Oracle BI Presentation Services. To use a repository variable in an expression, select it and double-click. Graph Used for Oracle BI Presentation Services. This kind of variable can be initiate with the help of SQL statement and ca ". Create a dashboard prompt with the following characteristics : Select only the column Calendar.Calendar Year. To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. 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. If this option is not selected, then the variable cannot be set. Relation (Table) Data (State) These multi-source session variables can be used in logical queries or in repository data filters, and contain the union of values from the different data sources. There is no restriction on the number of values that the multi-source session variable can hold. Names for all variables should be unique. BETWEEN case when substr('valueof(NQ_SESSION. In the Variable dialog, type a name for the variable. This variable is typically populated from the LDAP profile of the user. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. See "Examples of Initialization Strings" for examples. A proxy user is a user that has been authorized to act for another user. Compiler 2. I am confused on how to use the non-system session variable in Answers, says, in column formula, in a filter and in title view. 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. Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. Holds the Oracle BI Presentation Services user interface display language. You can also use this variable in a SQL statement. 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. Nominal When the execution of session variable initialization blocks cannot be deferred, a message is displayed that explains why. Data Structure See "About Row-Wise Initialization" for more information. In offline mode, the Set values for variables dialog is displayed so that you can populate :USER and :PASSWORD. 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. OBIEE - Where can I use a BI Server variable (session/repository) . When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. You cannot use any other value or expression as the default initializer for a static repository variable. Data Concurrency, Data Science If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. Select Row-wise initialization. Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. You can also use the row-wise initialization option to initialize a variable with a list of values. This option enables you to change this property without opening the initialization block dialog. You can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. This section provides information about working with session variables, and contains the following topics: Session variables obtain their values from initialization blocks. WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). Browser Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. 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 In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. 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 left pane, select Initialization Blocks under Repository or Session, depending on whether you want to enable or disable repository initialization blocks or session initialization blocks. Create a second session variable called MVCOUNTRY____ORCL, making sure to include four underscores between the variable name and the source name. In the View Data from Table dialog, type the number of rows and the starting row for your query, and then click Query. Debugging This variable has a possible value of 0 or 1. Scripting on this page enhances content navigation, but does not change the content in any way. After they are created, variables are available for use in Expression Builder. One source contains recent orders and the other source contains historical data. 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. Cube The variables receive their values from the initialization string that you type in the Initialization Block dialog. 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. If you select Database as the data source type, and select the Use OBI EE Server option.

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. Kurt Wolff, 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. To enable or disable an initialization block: In the Administration Tool, select Manage, then select Variables. Cube Process (Thread) Using the Multi-Source Session Variable in a Data Filter. The third case, dates, is the hardest. If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool. Because of this, do not put sensitive data like passwords in session or repository variables. StartDate)', 1, 3) = '201' then to_date(substr('valueof(NQ_SESSION.StartDate)',1,10), 'yyyy-mm-dd')else to_date('valueof(NQ_SESSION.StartDate)', 'mm/dd/yyyy') end AND case when substr('valueof(NQ_SESSION.EndDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION.EndDate)', 1, 3) = '201' then to_date(substr('valueof(NQ_SESSION.EndDate)',1,10), 'yyyy-mm-dd')else to_date('valueof(NQ_SESSION.EndDate)', 'mm/dd/yyyy') end, Tags: Selector See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). In the logical table source TIMES Fact from the logical fact table Times, let's fill in the where clause with the repository session variable. Data Partition In the Administration Tool, select Manage, then select Variables. See "About Row-Wise Initialization" for more information. 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. Holds the value the user enters as his or her logon name. Relational Modeling When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). 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). SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), #business-intelligence-suite-enterprise-edition-obiee. You should test the SQL statement outside of the Oracle BI Server, substituting valid values for the USER and PASSWORD variables. Is there a more recent similar source? Is Koestler's The Sleepwalkers still well regarded? Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs.

All associated variables of the initialization block and its unexecuted predecessors are updated with the values returned from the deferred execution. 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. 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. The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. Tree The new value is only valuable for the query. Privacy Policy This is another system variable whose presence is always assumed when the USER system session variable is used. In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. Used for Oracle BI Presentation Services. data for multiple clients and you structured the database so that data for each client was in a If these date prompts are setting report variables, you need to be able to deal with both formats. In the Variable Manager dialog, select Action > New > Session > Variable. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. To associate variables with initialization blocks: In the Variable Manager dialog, double-click the initialization block you want to edit. The value is case-insensitive. The names of system session variables are reserved and cannot be used for other types of variables. For session variables, you can select the following options: Enable any user to set the value. 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. For example, using the table values in the previous example, you would type the following SQL statement for the initialization string: This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE (for example, JOHN:JANE). The initialization block is used by session variables named PROXY or USER. Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). "store number" = VALUEOF(NQ_SESSION. See Creating Initialization Blocks for more information. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). If you select Database as the data source type: If you select Database as the data source type, and do not select the Use OBI EE Server option. Network Used for Oracle BI Presentation Services. Dates are, frankly, inordinately messy in OBIEE. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. Contains the application roles to which the user belongs. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. 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. Contains the locale of the user, typically populated from the LDAP profile of the user. Click Edit Data Source next to the Connection Pool field. Monitoring The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. Statistics 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 . 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. Why do you need to use session or request variables? Used for Oracle BI Server. Time The second case is where a session variable needs to be evaluated as a string. Identifies the query as a SELECT_PHYSICAL query. This section contains the following topics: The value of a static repository variable is initialized in the Variable dialog. In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION.
