Contains the groups to which the user belongs. "USER"), the syntax works. When you use these variables for Oracle BI Server, preface their names with NQ_SESSION. Tags: Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". BETWEEN case when substr('valueof(NQ_SESSION. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. At run time, if an initialization string for the database type has been defined, this string is used. Css Infra As Code, Web Mathematics It's meant to be a constant value. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". A common use for nonsystem session variables is setting user filters. Data Visualization Contains the groups to which the user belongs. 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 (). You can call a server variable by using this syntax : Data (State) You use the same procedure to define nonsystem session variables as for system session variables. This is another system variable whose presence is always assumed when the USER system session variable is used. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. The next step is to establish execution precedence. Connect and share knowledge within a single location that is structured and easy to search. Data Type Ratio, Code Debugging 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. Static repository variables must have default initializers that are constant values. In other words, if you change the SQL Server back-end database to Oracle, the query will still work. 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. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. For Example the report looks like this Region VALUEOF (REGION) SALES North Some value from North Variable 100 Number repository. There are two classes of variables: repository variables and session variables. Privacy Policy Text Relational Modeling Identifies the query as a SELECT_PHYSICAL query. See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. This variable has a possible value of 0 or 1. OBIEE - How and where can I set a Request variable (SET VARIABLE) ? If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. Testing Security Using the Multi-Source Session Variable in a Logical Query. [nQSError: 23006] The session variable, NQ_SESSION.user, has no value definition. This variable has a value of Yes. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). 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 SQL statement must reference physical tables that can be accessed using the connection pool specified in the Connection Pool field in the Initialization Block dialog. I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. Data Persistence Cube ':PASSWORD' (note the colon and single quotes) is the password the user enters. This variable is typically populated from the LDAP profile of the user. Process (Thread) In the Session Variable dialog, type a variable name. This option enables you to change this property without opening the initialization block dialog. Selector 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. vegan) just to try it, does this inconvenience the caterers and staff? For example, the following CASE statement is identical to the one explained in the preceding example, except that variables have been substituted for the constants: You cannot use variables to represent columns or other repository objects. 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. Automata, Data Type Data Structure "SV_STORE_NBR"']}, @{biServer.variables['NQ_SESSION.storenbr']}, @{biServer.variables['NQ_SESSION."storenbr"']}. Design Pattern, Infrastructure A repository variable has a single value at any point in time. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. 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. 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. In the Variable Manager dialog, double-click the last initialization block that you want to be initialized. An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. 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. See "About Connection Pools for Initialization Blocks" for more information. 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. Function If you select this option, execution of the initialization block is deferred until an associated session variable is accessed for the first time during the session. If the SQL statement contains an error, the database returns an error message. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. Dom If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. To remove a variable from association with this block, select the variable and click Remove. You use the same procedure to define nonsystem session variables as for system session variables. 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). In the Set value for the variables dialog, verify the information is correct, and then click OK. In the Session Variable dialog, type a variable name. Data Quality Dynamic repository values can be set up to do it automatically. The SQL statement you use to refresh the variable might be written for a specific database. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. Using the Multi-Source Session Variable in a Data Filter. Is Koestler's The Sleepwalkers still well regarded? 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. Nominal separate catalog. Collection In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. Data Partition For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. Trigonometry, Modeling Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. 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. Http Network biServer is good where biserver is not good. If the SQL statement contains an error, the database returns an error message. Data Science What tool to use for the online analogue of "writing lecture notes on a blackboard"? 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(). You can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. NQ_SESSION.ROLES is a session variable that returns a semicolon delimited string of roles assigned to the . was shown. 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. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. Kurt Wolff, This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. 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. Data Science Server Presentation Service Installed On Two Machines. 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. See "Assigning a Name and Schedule to Initialization Blocks" for more information. 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. Table 19-2 shows the table in this example. 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. Variables should be used as arguments of the function VALUEOF(). variables is plural. For example, you have This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. (HY000) SQL Issued: SELECT VALUEOF(NQ_SESSION.user) FROM "Sample . Each query can refresh several variables: one variable for each column in the query. 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). When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). For more information, see Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. Each instance of a session variable could be initialized to a different value. 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. You can edit repository initialization blocks, or session initialization blocks. This section provides information about working with session variables, and contains the following topics: Session variables obtain their values from initialization blocks. However, the cached results might not contain the most current session variable values. 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. 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. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. To select a data source and connection pool for initialization blocks: In the Variable Manager dialog, double-click the initialization block you want to edit. 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. 2. Url This variable has a value of Yes. See <> for more information. Distance Order See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. 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. 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). GUIDs for application roles are the same as the application role names. In the User/Application Role Permissions dialog, click the Data Filters tab. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. The names of system session variables are reserved and cannot be used for other types of variables. Debugging In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. 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 Scripting on this page enhances content navigation, but does not change the content in any way.
