Relation (Table) You open initialization block B, and then specify that block A will execute before block B. Graph If Prime Time were one of those segments and corresponded to the hours between 5:00 PM and 10:00 PM, you could create a CASE statement like the following: where Hour is a logical column, perhaps mapped to a timestamp physical column using the date-and-time Hour(<>) function. Used for Oracle BI Server. Infra As Code, Web Values in repository and session variables are not secure, because object permissions do not apply to variables. Such directories begin with sk_. 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)? 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. OBIEE - How to set and use a server variable (system/repository) of type date ? Grammar Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. OAuth, Contact Contains the time zone of the user, typically populated from the LDAP profile of the user. See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. This article gives an How-to : OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? Data Processing OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. The names and values of the session variables reside in an external database that you access through a connection pool. When using external table authentication with Delivers, the portion of the SQL statement that makes up the :PASSWORD constraint must be embedded between NQS_PASSWORD_CLAUSE clauses. In the User/Application Role Permissions dialog, click the Data Filters tab. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . Network How does the NLT translate in Romans 8:2? The Oracle BI Server uses the cached results for subsequent sessions. OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. 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. It seems that OBIEE save the default initializer value in the same space than for a repository variable. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Rather than entering the numbers 17 and 23 into this expression as constants, you could use the Variable tab of the Variable dialog to set up a static repository variable named prime_begin and initialize it to a value of 17, and create another variable named prime_end and initialize it to a value of 23. 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. 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. Execution of session variable initialization blocks during session logon can be deferred until their associated session variables are actually accessed within the session. Not the answer you're looking for? The SQL SELECT statement in the Default initializer list can contain multiple columns. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Operating System However, the cached results might not contain the most current session variable values. DataBase See "Examples of Initialization Strings" for additional examples. If a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. In the right pane, right-click the initialization block you want to enable or disable. Then, you explicitly define session variables for each source. Data Warehouse 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. Design Pattern, Infrastructure To create a new initialization block, click New. Cryptography Http Data Persistence 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. 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. Server Presentation Service Installed On Two Machines. 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. How to get the closed form solution from DSolve[]? Select Row-wise initialization. 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. Instead, the Oracle BI Server creates new instances of those variables whenever a user begins a new session. Select a discussion category from the picklist. Users can select a language on the sign-in page for Oracle BI EE, or they can change the language setting on the Preferences tab of the My Account dialog after signing in. In the Identity Manager dialog, in the tree pane, select BI Repository. You need to describe the content of these sources on the Content tab of the Logical Table Source dialog. In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. data for multiple clients and you structured the database so that data for each client was in a For repository variable initialization blocks, when you open a repository in online mode, the value shown in the Default initialization string field of the Initialization Block dialog is the current value of that variable as known to the Oracle BI Server. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. See "Testing Initialization Blocks" for more information. Compiler If you select Database as the data source type: If you select Database as the data source type, and do not select the Use OBI EE Server option. When you select the Use OBI EE Server option, there is no need for a connection pool, because the SQL statement is sent to the Oracle BI Server and not directly to the underlying database. Security Sensitive. You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. The default location for the nqquery.log file is: You can use the row-wise initialization option to create session variables dynamically and set their values when a session begins. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Using the Multi-Source Session Variable in a Logical Query. Determines if the initialization blocks required for authentication are executed. Compiler SQL -SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), Data filter condition is set on the Fact & Dimension tables in the application role. Create a row-wise initialization block called mvcountry_sebl_init with the following SQL for Default initialization string: Create a second row-wise initialization block called mvcountry_orcl_init with the following SQL for Default initialization string: Still in the Variable Manager, select Action > New > Session > Variable. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. DataBase Choose Enable or Disable from the right-click menu. Holds the value the user enters. Log, Measure Levels Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. 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. If any of the row-wise initialization blocks returns null results, this is logged in the Oracle BI Server log, nqserver.log. A repository variable has a single value at any point in time. [emailprotected] 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. In the Set value for the variables dialog, verify the information is correct, and then click OK. Contains the application roles to which the user belongs. Asking for help, clarification, or responding to other answers. In offline mode, the Set values for variables dialog is displayed so that you can populate :USER and :PASSWORD. For example, I have declared and initialised 3 server variables: All 3 contain a value after logging on, I verified this in the obiee admin tool 'manage sessions' screen. Why must a product of symmetric random variables be symmetric? Contains the time zone of the user, typically populated from the LDAP profile of the user. In the [Repository|Session] Variable Initialization Block Data Source dialog, click Test. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. ", Example message: "The execution of init block 'A_blk' cannot be deferred as it does not have a connection pool.". Data Quality Statistics See "Creating Initialization Blocks" for more information. The new value is only valuable for the query. You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. 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. Browser For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. Click Link to associate an existing variable with an initialization block. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). For example, suppose you want to create an expression to group times of day into different day segments. Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information. If you selected Custom Authenticator for your data source type, perform the following steps: Click Browse to select an existing custom authenticator, or click New to create one. When a user belongs to multiple Catalog groups, include the Catalog group names in the same column, separated by semicolons (for example, WebgroupA;WebgroupB;WebgroupC). The multi-source session variable will fail only if all of the component initialization blocks return null values. 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. 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. Variables should be used as arguments of the function VALUEOF(). In the Variable Manager dialog, select Action > New > Session > Variable. 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. 2. The values remain unchanged for the duration of the session. 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. Process (Thread) Grammar "ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." Story Identification: Nanomachines Building Cities, Ackermann Function without Recursion or Stack. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. For example, this option lets non-administrators to set this variable for sampling. For session variables, you can select the following options: Initialization Strings Used in Variables to Override Selection Steps. To learn more, see our tips on writing great answers. There is no restriction on the number of values that the multi-source session variable can hold. Automata, Data Type There are two types of session variables: system and nonsystem. The names of system session variables are reserved and cannot be used for other types of variables. However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. The repository variable, NQ_SESSION.MyYear, has no value definition. If there are fewer variables than columns, extra column values are ignored. You can use the Variable Manager in the Administration Tool to enable and disable initialization blocks. Http When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. An error will generate if a session variable is used. Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition, Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition, Allow first Connection Pool for Init Blocks, Action > New > Session > Initialization Block, "Syntax and Usage Notes for SELECT_PHYSICAL", "About Using Initialization Blocks with Variables", "When Execution of Session Variable Initialization Blocks Cannot Be Deferred", "About Connection Pools for Initialization Blocks", "Assigning a Name and Schedule to Initialization Blocks". Holds the name of the proxy user. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Presentation Services. See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. This option is for session variable initialization blocks only. This chapter contains the following topics: Working with Multi-Source Session Variables. In the [Repository|Session] Variable Initialization Block dialog, click Edit Execution Precedence. Custom Authenticator: For session variables. This kind of variable can be initiate with the help of SQL statement and ca ". 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. The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. For more information, see Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. Names for all variables should be unique. By using OBIEE variables and a custom control table in Snowflake, we can achieve the same functionality without having to continuously make metadata updates or worry about the number of connection pools becoming a maintenance nightmare. (Session init blocks only) Select an option. This variable has a possible value of 0 or 1. If every new session needs the most current set of session variables and their corresponding values, you should clear this option. a fiscal calendar) that you have stored in a Periods table, you can write the analogous SQL for that calendar. To accurately reflect the new content of the recent source, you would have to modify the fragmentation content description manually. For example, suppose you have two sources for information about orders. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. Trigonometry, Modeling 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. Operating System Monitoring For static repository variables, the value you specify in the Default initializer window persists. To create a multi-source session variable, you first create row-wise initialization blocks for each source. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. COMPANYID is the name of a physical column. OBIEE - How and where can I set a Request variable (SET VARIABLE) ? 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. The table describes the available system session variables. 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. One source contains recent orders and the other source contains historical data. A common way to set up a request variable in order to set a session repository variable is to create a dashboard prompt. For example, using the table values in the previous example, you would type the following SQL statement for the initialization string: This SQL statement populates the variable LIST_OF_USERS with a list, separated by colons, of the values JOHN and JANE (for example, JOHN:JANE). Dimensional Modeling This happens automatically when you double-click the variables to paste them into the expression. Html OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? In the Administration Tool, select Manage, then select Variables. This variable has a possible value of 0 or 1. This section contains the following topics: The value of a static repository variable is initialized in the Variable dialog. If this option is not selected, then the variable cannot be set.
