I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. Selecting the Use caching option directs the Oracle BI Server to store the results of the query in a main memory cache. Mathematics Contains the groups to which the user belongs. You must select a connection pool before typing an initialization string. rev2023.3.1.43269. Holds the value the user enters as his or her logon name. 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. Each instance of a session variable could be initialized to a different value. Data Processing Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. In the Session Variable dialog, type a variable name. If you can get to set a number request variable because it always add quotes, it's a bug because the value is independent from the data type of your presentation variable (works for the version 10.3.4.1). Tree See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. This system session variable overrides a variable defined in the Users object in the Administration Tool. "storenbr"), What am I missing? Data Warehouse The S of Server must be in uppercase. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. System session variables are session variables that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes. 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. OBIEE - How and where can I set a Request variable (SET VARIABLE) ? 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 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. 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. For session variable initialization blocks, you can select Row-wise initialization. Contains the application roles to which the user belongs. Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). Data Visualization When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Choose Enable or Disable from the right-click menu. 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. 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. . This option is for session variable initialization blocks only. 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 following list summarizes the scenarios in which execution of session variable initialization blocks cannot be deferred: The Row-wise initialization option is selected in the Session Variable Initialization Block Variable Target dialog and the variables have not been declared explicitly with default values. To learn more, see our tips on writing great answers. 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. Truce of the burning tree -- how realistic? Why must a product of symmetric random variables be symmetric? 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. Instead, the connection pool is blacklisted and subsequent initialization blocks for that connection pool are skipped. In the following example, the session variable RETAILERID has been assigned a numeric value. COMPANYID is the name of a physical column. This article show you with the help of the sh schema a little example. Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. Asking for help, clarification, or responding to other answers. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. Does Cosmic Background radiation transmit heat? 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. (Optional) Click Test to test the data source connectivity for the SQL statement. Relation (Table) Contains the locale of the user, typically populated from the LDAP profile of the user. There are many times when it is very beneficial to pass the value of session variables (or report variables) into the SQL used to define a Select table in the physical layer. Session variables are created and assigned a value when each user logs on. See "Examples of Initialization Strings" for examples. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. In the [Repository|Session] Variable Initialization Block Data Source dialog, click Test. 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. 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. BETWEEN case when substr('valueof(NQ_SESSION. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. Select the type of variable: Static or Dynamic. The variables receive their values from the initialization string that you type in the Initialization Block dialog. In the Identity Manager dialog, in the tree pane, select BI Repository. The Use caching option is automatically selected when you select the Row-wise initialization option. To create a new initialization block, click New. 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 new value is only valuable for the query. For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. For example, you have How to get the closed form solution from DSolve[]? The third case, dates, is the hardest. 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. Html You cannot use variables to represent columns or other repository objects. 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.

This system session variable overrides a variable defined in the Users object in the Administration Tool. The SQL SELECT statement in the Default initializer list can contain multiple columns. For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. 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. The tables do not have to be included in the Physical layer of the metadata. 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. Log, Measure Levels There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. Operating System 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. 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. Tags: 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. If you do not want this to occur, use the Undo Check Out option. Data Type (Apart from the obvious answer: it's a bug. From the Data Source Type list, select one of the following types. Names for all variables should be unique. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Click Link to associate an existing variable with an initialization block. To use a repository variable in an expression, select it and double-click. Repository variables and system and nonsystem session variables are represented by a question mark icon. Used to enable or disable Oracle BI Server result cache hits. WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. When you select the Use OBI EE Server option for an initialization block: Execution precedence does not apply, because during user login, an initialization block with the Use OBI EE Server option selected is executed after initialization blocks with the Use OBI EE Server option not selected. If a law is new but its interpretation is vague, can the courts directly ask the drafters the intent and official interpretation of their law? ), #business-intelligence-suite-enterprise-edition-obiee. For example, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth. 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. You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. 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. This is another system variable whose presence is always assumed when the USER system session variable is used. When you use these variables for Oracle BI Server, preface their names with NQ_SESSION. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'A' which is security sensitive.". When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. The Results dialog lists the variables and their values. To reorder variables, select a variable and click Up or Down. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). It will not change unless you change it. The above query example in the initialization block uses a join query with multiple tables from different data sources (for example, SQLServer, Oracle and XML Files). The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). Data Quality 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. Holds the value the user enters. 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. In the User/Application Role Permissions dialog, click the Data Filters tab. In the Session Variable dialog, type a variable name. Instead, the Oracle BI Server creates new instances of those variables whenever a user begins a new session. User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. You can then use the SQL IN operator to test for values in a specified list. You can also use this variable in a SQL statement. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services. Used to enable or disable Oracle BI Server plan cache seeding. For example, this option lets non-administrators to set this variable for sampling. Versioning Statistics 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. Linear Algebra There are two types of repository variables: static and dynamic. 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. In the Administration Tool, select Manage, then select Variables. Network When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). The next step is to associate variables with the initialization block. Dom Contains the time zone of the user, typically populated from the LDAP profile of the user. Init block 'B_blk' does not have "Allowed deferred execution" flag set. You schedule these queries to be executed by the Oracle BI Server. Then, you explicitly define session variables for each source. Otherwise, the default initialization SQL for the database type is used. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Server. Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. Order In addition, if an initialization block fails for a particular connection pool during Oracle BI Server start-up, no more initialization blocks using that connection pool are processed. Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. "store number" = VALUEOF(NQ_SESSION. New to My Oracle Support Community? (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. The next step is to select the data source and connection pool. The initialization block is a predecessor to another initialization block which does not have the Allow deferred execution option selected. For Initialization Block, select mvcountry_sebl_init. In the Select Connection Pool dialog, select the connection pool and click Select. There are two types of session variables: system and nonsystem. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. An error will generate if a session variable is used in the opaque view. This variable has a possible value of 0 or 1. Enable any user to set the value. Browser 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. See <> for more information. Data Science This variable has a possible value of 0 or 1. Process (Thread) Used to enable or disable Oracle BI Server plan cache hits. Because of this, do not put sensitive data like passwords in session or repository variables. Data Persistence How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? Because of this, if your repository has been upgraded from a previous release, you may see warnings in the Consistency Checker similar to the following: If you see warnings similar to this, update the relevant static repository variables so that the default initializers have constant values. Click here to get started. This chapter contains the following topics: Working with Multi-Source Session Variables. Monitoring The names and values of the session variables reside in an external database that you access through a connection pool. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. 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 is also saved as the author field for catalog objects. Holds the name of the proxy user. But when User B logs in he sees below error , when running the same report, [nQSError: 23006] The session variable, NQ_SESSION.PRODUCT, has no value definition. Infra As Code, Web Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. 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. 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. See "Setting Administration Tool Options" for more information. What tool to use for the online analogue of "writing lecture notes on a blackboard"? Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Design Pattern, Infrastructure Cryptography This section provides information about working with repository variables, and contains the following topics: A repository variable has a single value at any point in time. The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. Nominal The second case is where a session variable needs to be evaluated as a string. Function 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. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. Spatial Nominal 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. was shown. Lexical Parser Dom This saves the resources which would have been used to execute these unnecessary initialization blocks. Http This is another system variable whose presence is always assumed when the USER system session variable is used. 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). Any legal SQL can be executed using an initialization block, including SQL that writes to the database or alters database structures, assuming the database permits the user ID associated with the connection pool to perform these actions. A proxy user is a user that has been authorized to act for another user. (Session init blocks only) Select the following options when appropriate: Disabled. This variable is typically populated from the LDAP profile of the user. This causes block A to execute according to block B's schedule, in addition to its own. In the body, insert detailed information, including Oracle product and version. The initialization block is used by session variables where the Security Sensitive option is selected in the Session Variable dialog. However, the cached results might not contain the most current session variable values. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. Color 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. If you want the initialization block to be required, in the [Repository|Session] Variable Initialization Block dialog, select the Required for authentication option. 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. The Variable Manager appears. In offline mode, the Set values for variables dialog is displayed so that you can populate :USER and :PASSWORD. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. In the View Data from Table dialog, type the number of rows and the starting row for your query, and then click Query. To accurately reflect the new content of the recent source, you would have to modify the fragmentation content description manually. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled.
