Names for all variables should be unique. Time For Initialization Block, select mvcountry_orcl_init. You cannot use any other value or expression as the default initializer for a static repository variable. How to get the closed form solution from DSolve[]? See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. 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(). 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. OAuth, Contact 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. You can also use this variable in a SQL statement. Data Structure Is there a more recent similar source? 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. Javascript See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. Scripting on this page enhances content navigation, but does not change the content in any way. Session variables are primarily used when authenticating users against external sources such as database tables or LDAP servers. Shipping Testing 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. File System In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons,for example, RoleA;RoleB;RoleC. This variable is typically populated from the LDAP profile of the user. Data (State) Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'A' which is security sensitive.". After they are created, variables are available for use in Expression Builder. In the following example, the session variable RETAILERID has been assigned a numeric value. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. Example 19-2 A SQL Statement When Site Does Not Use Delivers. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Browser In the Set value for the variables dialog, verify the information is correct, and then click OK. In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. In the Application Role dialog, click Permissions. Click Link to associate an existing variable with an initialization block. This variable has a possible value of 0 or 1. Linear Algebra Cryptography Create a second session variable called MVCOUNTRY____ORCL, making sure to include four underscores between the variable name and the source name. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. This SQL contains two constraints in the WHERE clause: ':USER' (note the colon and single quotes) is the ID the user types when logging in. Linear Algebra 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. Find centralized, trusted content and collaborate around the technologies you use most. 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. Select Row-wise initialization. The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. The second case is where a session variable needs to be evaluated as a string. 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. If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). A repository variable has a single value at any point in time. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. 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, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. Why must a product of symmetric random variables be symmetric? For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . Design Pattern, Infrastructure WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. 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. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. Without using dynamic repository variables, you would describe the content of the source containing recent data with an expression such as: This content statement becomes invalid as new data is added to the recent source and older data is moved to the historical source. You need to describe the content of these sources on the Content tab of the Logical Table Source dialog. Because of this, do not put sensitive data like passwords in session or repository variables. 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. Text It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. Enable any user to set the value. Execution of session variable initialization blocks cannot be deferred in some circumstances. Log, Measure Levels If any of the row-wise initialization blocks returns null results, this is logged in the Oracle BI Server log, nqserver.log. You would initialize a session variable named Client, for example, that could be You should set the logging level to 2 for the administrator to provide the most useful level of information. variables is plural. In the Select Connection Pool dialog, select the connection pool and click Select. Kurt Wolff, 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. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. Data Warehouse Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Exists only for compatibility with previous releases. A common way to set up a request variable in order to set a session repository variable is to create a dashboard prompt. Network Ratio, Code Data Analysis If you select Database as the data source type, and select the Use OBI EE Server option. See "Assigning a Name and Schedule to Initialization Blocks" for more information. Contains a description of the user, typically populated from the LDAP profile of the user. You can also use this variable in a SQL statement. Data Science The values remain unchanged for the duration of the session. For example, suppose a repository has two initialization blocks, A and B. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. 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(). OBIEE - BI Server Patch (automatic update with a patch file) See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information. Compiler In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. biServer is good where biserver is not good. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. Holds the value the user enters as his or her logon name. 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). (Apart from the obvious answer: it's a bug. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. Order Why is the error occurring only for User B? In the Variable Manager dialog, select Action > New > Session > Variable. Such directories begin with sk_. Key/Value The call for a session variable is: VALUEOF("NQ_SESSION.Variable Name") DataBase 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. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. This value persists, and does not change until an administrator decides to change it. When you have create a server variable, you have to reference it. Holds the Oracle BI Presentation Services user interface display language. Computer 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. This variable has a possible value of 0 or 1. Contains the time zone of the user, typically populated from the LDAP profile of the user. Dynamic repository variables are useful for defining the content of logical table sources. 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. When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. Names for all variables should be unique. If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. Cause had logged in as admin and i got back the value (get back number: 2) as I expected In the start_level column of the business layer i used the following script as source: INDEXCOL( VALUEOF(NQ_SESSION . I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. Don't have a My Oracle Support Community account? data for multiple clients and you structured the database so that data for each client was in a Data Processing (Optional) Click Test to test the data source connectivity for the SQL statement. Monitoring When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. 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. Discrete Text The new value is only valuable for the query. Instead, the connection pool is blacklisted and subsequent initialization blocks for that connection pool are skipped. For example, suppose you have two sources for information about orders. When filtering cache table matches, the looks at the parent database object of each column or table that is referenced in the logical request projection list. See "Examples of Initialization Strings" for additional examples. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. 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)? For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. 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. Data Persistence Relation (Table) In the [Repository|Session] Variable Initialization Block Variable Target dialog, perform one of the following steps: Associate variables with the initialization block by doing one of the following: Click New, and in the Variable dialog, create a new variable. The query works because when you select the Use OBI EE Server option, the query is rewritten by the BI Server for the specified data sources. Status. This variable has a possible value of 0 or 1. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Presentation Services. To create a new initialization block, click New. In the Variable Manager dialog, select Action > New > Repository > Variable. Contains the locale of the user, typically populated from the LDAP profile of the user. 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.
