Because of this, do not put sensitive data like passwords in session or repository variables. The multi-source session variable will fail only if all of the component initialization blocks return null values. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. While the main focus of this section is on the definition and usage of multi-source session variables, you may also select the VALUEOF the component session variables in logical queries and data filters. This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. Otherwise, the default initialization SQL for the database type is used. This variable has a possible value of 0 or 1. Privacy Policy vegan) just to try it, does this inconvenience the caterers and staff? Used to enable or disable Oracle BI Server plan cache seeding. I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. In the Select Connection Pool dialog, select the connection pool and click Select. Http Graph Cube The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. 3. 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. 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. Nominal Example 19-3 A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting. There are three cases to consider, depending on whether the session variable is intended to filter a column that has a numeric, varchar, or date data type. OBIEE 11g - The session variable, NQ_SESSION.VARIABLE, has no value definition user11173172 Feb 20 2015 edited Feb 27 2015 Hello, I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security.

A common use for nonsystem session variables is setting user filters. Data Warehouse Order Cache hits would only occur on cache entries that included and matched all security-sensitive variables. 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. Contains a description of the user, typically populated from the LDAP profile of the user. Collection At run time, if an initialization string for the database type has been defined, this string is used. Network COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . 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. Used to enable or disable Oracle BI Server subrequest cache hits and seeding.

Holds the Oracle BI Presentation Services user interface display language. Log, Measure Levels To add a Default initializer value, type the value in the Default initializer box, or click the Expression Builder button to use Expression Builder. Otherwise, a default initialization SQL string is used. For session variables, you can select the following options: Enable any user to set the value. Computer Compiler OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? Static repository variables must have default initializers that are constant values. Session variables are created and assigned a value when each user logs on. This can reduce session startup time. Browser 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. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. I need it to be the values of TestVar1 and TestVar3, that were applied in a previous prompt as request variables, multiplied, but all I get is the original values from the session variables. The query returns data only if the user ID and password match values found in the specified table. 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). Data Visualization Statistics 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. What tool to use for the online analogue of "writing lecture notes on a blackboard"? Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. This option enables you to change this property without opening the initialization block dialog. OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. COMPANYID is the name of a physical column. Does Cosmic Background radiation transmit heat? 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. In the right pane, right-click the initialization block you want to enable or disable. 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 the user modifies the date range using the first calendar, the format of the first date changes. The repository variable, NQ_SESSION.MyYear, has no value definition. Grammar You can edit repository initialization blocks, or session initialization blocks. 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 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. 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. Key/Value Determines if the initialization blocks required for authentication are executed. To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). 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. See "Examples of Initialization Strings" for additional examples. You should test the SQL statement using the Test button or a SQL tool such as the Oracle BI Client utility. You can also use the row-wise initialization option to initialize a variable with a list of values. To create initialization blocks, perform the steps in the following sections: Assigning a Name and Schedule to Initialization Blocks, Selecting and Testing the Data Source and Connection Pool. You cannot use any other value or expression as the default initializer for a static repository variable. You can't use SQL to set your default initializer, that's why you only see Constants as an option. See "Setting Administration Tool Options" for more information. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. The Variable Manager appears. 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. 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. Why is the error occurring only for User B? In the Session Variable dialog, type a variable name. Click OK to return to the Initialization Block dialog. Log, Measure Levels If the SQL statement contains an error, the database returns an error message. "store number" = VALUEOF(NQ_SESSION. See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. In the Variable Manager dialog, select Action > New > Repository > Variable. Used for Oracle BI Server. Use the Initialization Block list to select an initialization block that will be used to refresh the value on a continuing basis. Compiler When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. 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. For Initialization Block, select mvcountry_sebl_init. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. variables is good where variable is bad.

Function Number In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. In order to create an OBIEE Analytics Agent, you have to connect to Oracle BI Analytics: If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). You do not need to set up the PASSWORD variable, and you can use this variable in a database connection pool to allow passthrough login using the user ID and password of the user. To use a repository variable in an expression, select it and double-click. This variable has a possible value of 0 or 1. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. Spatial If you select this option, the initialization block is disabled. (Session init blocks only) Select the following options when appropriate: Disabled. If you select this option, this initialization block must succeed for users to log in. You can also use this variable in a SQL statement. 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. Initializing Dynamic Repository Variables. 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)? You can modify the value of the session variable with a dashboard prompt. 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. You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. File System Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons,for example, RoleA;RoleB;RoleC. The names and values of the session variables reside in an external database that you access through a connection pool. Operating System Process (Thread) If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). Linear Algebra Data Structure For Oracle, you could write: trunc(sysdate) - to_char(sysdate,'D')+1 CurrentSunday, , trunc(sysdate) - to_char(sysdate,'D')+2 CurrentMonday, , trunc(sysdate) - to_char(sysdate, 'D')+7 CurrentSaturday, , trunc(sysdate) - to_char(sysdate,'D')+8 NextSunday, , trunc(sysdate) - to_char(sysdate,'D') PreviousSaturday, , trunc(sysdate) - to_char(sysdate,'D')+2-8 PreviousSunday, , trunc(sysdate) - to_char(sysdate,'D')+2-7 PreviousMonday, , cast(to_char(trunc(sysdate), 'YYYY') as INT) CurrentYear, , Cast(to_char(trunc(sysdate), 'YYYY')-1 as INT) PreviousYear, , add_months(trunc(last_day(sysdate)),-1) + 1 CurrentMonthFirstDay, , last_day(trunc(sysdate)) CurrentMonthLastDay, , add_months(TRUNC(last_day(sysdate)),-2) + 1 PreviousMonthFirstDay, , case when last_day(SYSDATE) = SYSDATE then TRUNC(SYSDATE) else add_months(TRUNC(last_day(sysdate)),-1) end LASTDAYCOMPLETEMONTH. The intent is to filter that data just for that retailer. To create a new initialization block, click New. How can the mass of an unstable composite particle become complex?

In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. This causes block A to execute according to block B's schedule, in addition to its own. Ratio, Code You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). Only repository variables can be used in the definition. Relation (Table) Example 19-2 A SQL Statement When Site Does Not Use Delivers. Is there a limit on number of values session variable can hold. Time (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. 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. NQ_SESSION.ROLES is a session variable that returns a semicolon delimited string of roles assigned to the . Holds the Oracle BI Presentation Services user interface display language. 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. Click Edit Data Source next to the Connection Pool field. Click here to get started. Contains the locale of the user, typically populated from the LDAP profile of the user. This is another system variable whose presence is always assumed when the USER system session variable is used. For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. Allow deferred execution. Dom This variable is typically populated from the LDAP profile of the user. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. Names for all variables should be unique. The names of system session variables are reserved and cannot be used for other types of variables. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Contains the time zone of the user, typically populated from the LDAP profile of the user. To see the value of the server variable, I have had a text box dashboard below the dashboard prompt with this code : Then when you set for instance the dashboard prompt to 1996 and hit the go button, you will retrieve this result : The value of the repository session variable is not changed. The query returns data only if the user ID and password match values found in the specified table. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. Legacy groups are mapped to application roles automatically. 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. 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. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. Close the Variable Manager and save the repository. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. See "Testing Initialization Blocks" for more information. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Server. 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. You can find an example of a dynamic essbase connection pool in this post of christian berg: In the bookshel Version 10.1.3.2, it's written that Only repository variables can be used in the definition. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. separate catalog. You can use the Variable Manager in the Administration Tool to enable and disable initialization blocks. was shown. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. [emailprotected] If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. Debugging In the following example, the session variable RETAILERID has been assigned a numeric value. This section explains how to create session variables. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. 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. Used to enable or disable Oracle BI Server plan cache hits. Learn about session variables and how to create them. The next step is to select the data source and connection pool. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements (for example, figures such as GIF files).
