This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. GUIDs for application roles are the same as the application role names. To view full details, sign in to My Oracle Support Community. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. Process (Thread) Operating System In the Variable Manager dialog, select Action > New > Repository > Variable. 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 query returns data only if the user ID and password match values found in the specified table. 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. There are two types of repository variables: static and dynamic. This variable is typically populated from the LDAP profile of the user. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". This happens automatically when you double-click the variables to paste them into the expression. To create a session variable: In the Administration Tool, select Manage, then select Variables. Click Link to associate an existing variable with an initialization block. OBIEE - Where can I use a BI Server variable (session/repository) ? Data Analysis You can use the Variable Manager in the Administration Tool to enable and disable initialization blocks. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Used for Oracle BI Presentation Services. Then, you explicitly define session variables for each source. Text Used for Oracle BI Presentation Services. Dimensional Modeling Asking for help, clarification, or responding to other answers. . "storenbr"), What am I missing? Dom For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. 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). 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. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. See "Testing Initialization Blocks" for more information. This option is for session variable initialization blocks only. To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. This saves the resources which would have been used to execute these unnecessary initialization blocks. You cannot use any other value or expression as the default initializer for a static repository variable. Dom Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. Selector 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. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. 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. 3. There are two types of session variables: system and nonsystem. 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. Variables should be used as arguments of the function VALUEOF(). In the Administration Tool, select Manage, then select Variables. In the Session Variable dialog, type a variable name. Session variables that are not needed during the session do not have their initialization blocks executed. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. 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. 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. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. Don't forget the quotes which enclose the Variable Name. For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Therefore, when you associate variables with an initialization block, the value returned in the first column is assigned to the first variable in the list. Statistics If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool. For example, the format of a date report variable can vary, depending on whether the user has changed the default value set by a dashboard calendar prompt. Why is the error occurring only for User B? For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. Data Partition Cube 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. With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. See "About Row-Wise Initialization" for more information. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. Exists only for compatibility with previous releases. 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. 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. Lexical Parser Used for Oracle BI Presentation Services.

The next step is to select the data source and connection pool. Data Science Dynamic repository variables are useful for defining the content of logical table sources. This variable has a possible value of 0 or 1. 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. Data Visualization Data Persistence File System The next step is to associate variables with the initialization block. Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. Css You can also right-click an existing initialization block in the Variable Manager and choose Disable or Enable. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). To assign a name and schedule to initialization blocks: In the Variable Manager dialog, from the Action menu, choose New > Repository (or Session) > Initialization Block. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information. DataBase Log, Measure Levels 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. In the Application Role dialog, click Permissions. 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. For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr Holds the name of the proxy user. See "Setting Administration Tool Options" for more information. For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. From the Data Source Type list, select one of the following types. rev2023.3.1.43269. variables is good where variable is bad. The Variable Manager appears. Select a discussion category from the picklist. If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). 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. In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. You can't use SQL to set your default initializer, that's why you only see Constants as an option. This is another system variable whose presence is always assumed when the USER system session variable is used. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. The second case is where a session variable needs to be evaluated as a string. Cryptography Computer Scripting on this page enhances content navigation, but does not change the content in any way. The value of LOGLEVEL, a number between 0 and 5, determines the logging level that the Oracle BI Server uses for user queries. Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. 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. See "Assigning a Name and Schedule to Initialization Blocks" for more information. Shipping Graph 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. 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). The new value is only valuable for the query. Monitoring Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. One source contains recent orders and the other source contains historical data. Names for all variables should be unique. To use the multi-source session variable MVCOUNTRY in a data filter, perform the following steps: In the Administration Tool, select Manage, then select Identity. This causes block A to execute according to block B's schedule, in addition to its own. If you stop and restart the Oracle BI Server, the server automatically executes the SQL statements in repository variable initialization blocks, reinitializing the repository variables. The repository variable, NQ_SESSION.MyYear, has no value definition. See "About Row-Wise Initialization" for more information. Blog, KPI Partners provides strategic guidance and technology systems for clients wishing to solve complex business challenges involving cloud applications and big data.Learn more, Oracle | Tableau | Snowflake | AWS | Azure | ConfluentQlik | MapR | Cloudera | Hortonworks | DataStax | SAPTeradata | NetSuite | Salesforce | Attunity | Denodo |NumerifyView all, KPI Partners, Inc.39899 Balentine Drive, Suite #212, BigQuery to optimize cost and performance, Data Lake Challenges with Databricks Delta Lake, Manual performance optimization in Denodo, Real-Time Supply Chain and Inventory Analytics, Snowflake secure views vs views in Oracle, traditional software development methodology.

The Required for authentication option is selected in the Session Variable Initialization Block dialog. Data Structure In one of my report columns I need to get value of session variables like VALUEOF (NQ_SESSION.COLUMN1). When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. Why do you need to use session or request variables? 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. The query returns data only if the user ID and password match values found in the specified table. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. For example, you have 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. Compiler The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. If you select Database as the data source type, and select the Use OBI EE Server option. Required for authentication. 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 . See "Testing Initialization Blocks" for more information. 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 Variable Manager dialog has two panes. 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. 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. The multi-source session variable will fail only if all of the component initialization blocks return null values. 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. Url Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. Names for all variables should be unique. In the Select Connection Pool dialog, select the connection pool and click Select. Each instance of a session variable could be initialized to a different value. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. [nQSError: 23006] The session variable, NQ_SESSION.user, has no value definition. In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. Create a second session variable called MVCOUNTRY____ORCL, making sure to include four underscores between the variable name and the source name. This variable has a possible value of 0 or 1. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. The variables receive their values from the initialization string that you type in the Initialization Block dialog. 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. 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. 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. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. You can overtype this string. The values remain unchanged for the duration of the session. Assume today is June 10. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. ':PASSWORD' (note the colon and single quotes) is the password the user enters. Used for Oracle BI Presentation Services. Order Note: The Test button is disabled when the Use OBI EE Server option is selected in offline mode. 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. Specifies the Catalog groups (Presentation Services groups) to which the user belongs, if any. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Presentation Services. It's meant to be a constant value. When Jane connects to the Oracle BI Server, her session contains three session variables from row-wise initialization: LEVEL, containing the value 8; STATUS, containing the value FULL-TIME; and GRADE, containing the value AAA. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. All associated variables of the initialization block and its unexecuted predecessors are updated with the values returned from the deferred execution. For example, the NQ_SYSTEM initialization block is used to refresh system session variables. 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. Design Pattern, Infrastructure The initialization block is used to set your session variable to a dynamic value. Is there a limit on number of values session variable can hold. 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 only way I can actually address the other two values to set the default value, is through the default selection type 'sql result', in which I look up the variable value using the dimension to which it refer: WHERE "dimension". 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. Security Sensitive. See "Examples of Initialization Strings" for examples. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. Each query can refresh several variables: one variable for each column in the query. Kurt Wolff, In the [Repository|Session] Variable Initialization Block dialog, click Edit Data Source. Data Concurrency, Data Science Privacy Policy See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). You can now use the multi-source session variable MVCOUNTRY in a logical query. In other words, if you change the SQL Server back-end database to Oracle, the query will still work. "USER"), the syntax works. This chapter contains the following topics: Working with Multi-Source Session Variables. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. Css For example, this option lets non-administrators to set this variable for sampling. See <
