Truce of the burning tree -- how realistic? 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 number of associated variables can be different from the number of columns being retrieved. If you select this option, the initialization block is disabled. Launching the CI/CD and R Collectives and community editing features for OBIEE 12C: dashboard prompt auto fill when selection is sql result, dashboard prompt doesn't work in obiee 11g when using javascript, Oracle gives error Message on prompt refresh, OBIEE 11 - How to export a multipage dashboard in excel without prompt, Using table function in OBIEE RPD (physical layer) and pass parameter from dashboard prompt to it, obiee12c dashboard prompts running before analysis filters. 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. Data Concurrency, Data Science Why do you need to use session or request variables? Close the Variable Manager and save the repository. For static repository variables, the value you specify in the Default initializer window persists. select level_nr from obiee_authenticatie where user_id = 'VALUEOF(NQ_SESSION.USER)' When testing in the variable manager it works perfect. Automata, Data Type (HY000) SQL Issued: SELECT VALUEOF(NQ_SESSION.user) FROM "Sample . 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. You use the same procedure to define nonsystem session variables as for system session variables. Javascript Javascript 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 OBIEE - Connection Pool: The picture below show a repository variable call but you can use in the same way the session variable syntax. 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. This value persists, and does not change until an administrator decides to change it. 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. 1. 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. Key/Value Statistics variables is good where variable is bad. The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. 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. Don't forget the quotes which enclose the Variable Name. However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. This variable has a possible value of 0 or 1. The SQL SELECT statement in the Default initializer list can contain multiple columns. In one of my report columns I need to get value of session variables like VALUEOF (NQ_SESSION.COLUMN1). Relation (Table) How does the NLT translate in Romans 8:2? The Oracle BI Server substitutes the value of the repository variable for the variable itself in the metadata. ':PASSWORD' (note the colon and the single quotes) is the password the user enters. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. 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. Linear Algebra Specifies the Catalog groups (Presentation Services groups) to which the user belongs, if any. This saves the resources which would have been used to execute these unnecessary initialization blocks. Dimensional Modeling Expression Builder pastes it into the expression at the active cursor insertion point. In the Select Connection Pool dialog, select the connection pool and click Select. Using the Multi-Source Session Variable in a Logical Query. Used for Oracle BI Presentation Services. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. 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. There are two types of session variables: system and nonsystem. Data Persistence When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. If this option is not selected, then the variable cannot be set. Versioning You won't be able to use the Oracle date functions for many of the values you want, but you can still write the SQL to return the values according to the fiscal periods in your calendar using different methods. 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. 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. Statistics ':PASSWORD' (note the colon and single quotes) is the password the user enters. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). Color 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. WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). (Session init blocks only) Select an option. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. This can reduce session startup time. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. Process (Thread) The string you enter here is processed by the Oracle BI Server, and therefore as long as it is supported by the Oracle BI Server, the string will work with different data sources. OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. To use a repository variable in an expression, select it and double-click. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. Server Presentation Service Installed On Two Machines. Identifies the query as a SELECT_PHYSICAL query. 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. To create a new initialization block, click New. See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. This system session variable overrides a variable defined in the Users object in the Administration Tool. Used to enable or disable Oracle BI Server plan cache hits. OAuth, Contact You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. Monitoring Init block 'B_blk' does not have "Allowed deferred execution" flag set. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. You can use them to provide event-driven alerting, scheduled content publishing and conditional event-driven action execution. 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. repository. You should test the SQL statement using the Test button or a SQL tool such as the Oracle BI Client utility. To create a new initialization block, click New. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. For example, an initialization block might use the function pi(), which is specific to SQL Server. When you use these variables for Oracle BI Server, preface their names with NQ_SESSION. I have created variables with the same name using row vise initialization. See "About Using Initialization Blocks with Variables" for more information. An error will generate if a session variable is used. See "Setting Administration Tool Options" for more information. For session variables, you can select the following options: Initialization Strings Used in Variables to Override Selection Steps. Shipping 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. Contains the locale of the user, typically populated from the LDAP profile of the user. 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). COLUMN1 is having values VARIABLE1 , VARIABLE2 etc . Data (State) Network Used to enable or disable Oracle BI Server plan cache seeding. If you select Row-wise initialization, the Use caching option becomes available. Tree I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. 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. The Variable Manager dialog has two panes. Number Status. The S of Server must be in uppercase. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. Used for Oracle BI Presentation Services. Not the answer you're looking for? 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, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth. The initialization block is used by session variables named PROXY or USER. You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. Data (State) This variable has a possible value of 0 or 1. 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. Data Partition You cannot use variables to represent columns or other repository objects. If these date prompts are setting report variables, you need to be able to deal with both formats. Initialization blocks are used to initialize dynamic repository variables, system session variables, and nonsystem session variables. Holds the name of the proxy user. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. Privacy Policy Session variables that are not needed during the session do not have their initialization blocks executed. Html If you select Database as the data source type, and select the Use OBI EE Server option. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. For example, suppose you want to create an expression to group times of day into different day segments. 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. 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. The multi-source session variable will fail only if all of the component initialization blocks return null values. 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. The query returns data only if the user ID and password match values found in the specified table. Why is the error occurring only for User B? 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. Logical Data Modeling Spatial The third case, dates, is the hardest. In the body, insert detailed information, including Oracle product and version. Nominal When the user modifies the date range using the first calendar, the format of the first date changes. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. I try to display the variable by define it in column formula as VALUEOF(NQ_SESSION. For Oracle, you could write: trunc(sysdate) - to_char(sysdate,'D')+1 CurrentSunday, , trunc(sysdate) - to_char(sysdate,'D')+2 CurrentMonday, , trunc(sysdate) - to_char(sysdate, 'D')+7 CurrentSaturday, , trunc(sysdate) - to_char(sysdate,'D')+8 NextSunday, , trunc(sysdate) - to_char(sysdate,'D') PreviousSaturday, , trunc(sysdate) - to_char(sysdate,'D')+2-8 PreviousSunday, , trunc(sysdate) - to_char(sysdate,'D')+2-7 PreviousMonday, , cast(to_char(trunc(sysdate), 'YYYY') as INT) CurrentYear, , Cast(to_char(trunc(sysdate), 'YYYY')-1 as INT) PreviousYear, , add_months(trunc(last_day(sysdate)),-1) + 1 CurrentMonthFirstDay, , last_day(trunc(sysdate)) CurrentMonthLastDay, , add_months(TRUNC(last_day(sysdate)),-2) + 1 PreviousMonthFirstDay, , case when last_day(SYSDATE) = SYSDATE then TRUNC(SYSDATE) else add_months(TRUNC(last_day(sysdate)),-1) end LASTDAYCOMPLETEMONTH. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. There are two types of session variables: system and nonsystem. Is there a limit on number of values session variable can hold. To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. How to get the closed form solution from DSolve[]? Create a session variable called MVCOUNTRY____SEBL, making sure to include four underscores between the variable name and the source name. Legacy groups are mapped to application roles automatically. This option is for session variable initialization blocks only. Data (State) Contains the time zone of the user, typically populated from the LDAP profile of the user. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Server. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Compiler Security Holds the name of the proxy user. The initialization block is a predecessor to another initialization block which does not have the Allow deferred execution option selected. After they are created, variables are available for use in Expression Builder. ", Example message: "The execution of init block 'A_blk' cannot be deferred as it does not have a connection pool.". Http Used to enable or disable Oracle BI Server result cache hits. In order to create an OBIEE Analytics Agent, you have to connect to Oracle BI Analytics: A common use for nonsystem session variables is setting user filters. Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. The syntax is: WHERE COMPANYID=ValueOf (NQ_SESSION.RETAILERID) The second case is where a session variable needs to be evaluated as a string. Selecting the Use caching option directs the Oracle BI Server to store the results of the query in a main memory cache. Find centralized, trusted content and collaborate around the technologies you use most. Contains the application roles to which the user belongs. Dynamic repository values can be set up to do it automatically. ), #business-intelligence-suite-enterprise-edition-obiee. Debugging In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. Distance Contains the time zone of the user, typically populated from the LDAP profile of the user. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. 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. You can change this behavior so that the first connection pool is available for selection by selecting Allow first Connection Pool for Init Blocks in the Options dialog, although this is not recommended. In the Variable Manager dialog, select Action > New > Session > Variable. Design Pattern, Infrastructure 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 you are using a calendar thats different from the normal Gregorian calendar (i.e. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons (for example, RoleA;RoleB;RoleC). 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. Static repository variables must have default initializers that are constant values. To create a session variable: In the Administration Tool, select Manage, then select Variables. Note that the recommended practice is to use application roles rather than Catalog groups. You can get this warning when you perform a check global consistency. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. If you selected Use database specific SQL, then in the Database pane, expand and select the database. 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. Thanks for contributing an answer to Stack Overflow! Session variables are created and assigned a value when each user logs on. Dates are, frankly, inordinately messy in OBIEE. Only repository variables can be used in the definition. Unlike a repository variable, there are as many instances of a session variable as there are active sessions on the Oracle BI Server. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. When you have create a server variable, you have to reference it. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. 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. Time 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. Contains a description of the user, typically populated from the LDAP profile of the user. The first case is where a session variable has a numeric value. The value is case-insensitive. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Select a discussion category from the picklist. Compiler Then, in the Browse dialog, select the variable to be refreshed by this initialization block and click OK. For the Custom Authenticator data source type (Session variables only), the variable USER is required. Data Type Otherwise, the default initialization SQL for the database type is used. For more information, see Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. You can call a server variable by using this syntax : Data (State) 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. Security Sensitive. If a semicolon must be included as part of a Catalog group name, precede the semicolon with a backslash character (\). You can use the Variable Manager in the Administration Tool to define variables. 2. The obiee logical sql request doesn't contain any filter : The logical request doesn't contain any filter : But the final query, send in the database, contains one. Lexical Parser The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. This chapter contains the following topics: Working with Multi-Source Session Variables. Data Processing 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.
