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)? Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". To accurately reflect the new content of the recent source, you would have to modify the fragmentation content description manually. Session variables are created and assigned a value when each user logs on. Connect and share knowledge within a single location that is structured and easy to search. 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. For more information, see Oracle Fusion Middleware System Administrator's Guide for Oracle Business Intelligence Enterprise Edition. Css Discrete This option is for session variable initialization blocks only. 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. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). WHERE upper (SALESREP) = upper ('valueof (NQ_SESSION.USER)') The third case, dates, is the hardest. The format for the session variable names must be: where the separator must be exactly four underscore characters. For example, the NQ_SYSTEM initialization block is used to refresh 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. . 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). Instead, the Oracle BI Server creates new instances of those variables whenever a user begins a new session. Grammar Determines if the initialization blocks required for authentication are executed. This section contains the following topics: The value of a static repository variable is initialized in the Variable dialog. 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. If you select this option, this initialization block must succeed for users to log in. (Optional) Click Test to test the data source connectivity for the SQL statement. (Session init blocks only) Select an option. 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. Shipping To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. See "About Using Initialization Blocks with Variables" for more information. All associated variables of the initialization block and its unexecuted predecessors are updated with the values returned from the deferred execution. In the Application Role dialog, click Permissions. 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. This variable has a possible value of 0 or 1. 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 . Shipping Holds the Oracle BI Presentation Services user interface display language. The Results dialog lists the variables and their values. You cannot use any other value or expression as the default initializer for a static repository variable. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. So what *is* the Latin word for chocolate? The query returns data only if the user ID and password match values found in the specified table. GUIDs for application roles are the same as the application role names. 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. This saves the resources which would have been used to execute these unnecessary initialization blocks. This chapter contains the following topics: Working with Multi-Source Session Variables. Distance Don't forget the quotes which enclose the Variable Name. This variable has a possible value of 0 or 1. This variable is typically populated from the LDAP profile of the user. If you select this option, the initialization block is disabled. 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. Then, enter its associated string. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. 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. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Names for all variables should be unique. Number Otherwise, in the Default initialization string box, type the SQL initialization string needed to populate the variables. 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. Computer This variable has a possible value of 0 or 1. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. Contains a description of the user, typically populated from the LDAP profile of the user. To enable or disable an initialization block: In the Administration Tool, select Manage, then select Variables. Ive done it this way. (HY000) SQL Issued: SET VARIABLE MYYEAR='1998';SELECT TIMES_VIEW.calendar_year saw_0 FROM Test ORDER BY saw_0 Try to use the same letter case for the name of the variable (upper and lower). 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. Add is only available if there are initialization blocks that have not yet been selected. ':PASSWORD' (note the colon and the single quotes) is the password the user enters. vegan) just to try it, does this inconvenience the caterers and staff? In other words, if you change the SQL Server back-end database to Oracle, the query will still work. 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. 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. 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. Anybody who knows or can guess the name of the variable can use it in an expression in Answers or in a Logical SQL query. In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. Dynamic repository values can be set up to do it automatically. You use the same procedure to define nonsystem session variables as for system session variables. Linear Algebra Variables should be used as arguments of the function VALUEOF(). 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. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'A' which is security sensitive.". You cannot use variables to represent columns or other repository objects. 2. Dimensional Modeling 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). Data Structure The LDAP server name and the associated domain identifier appear in the Name and Domain identifier columns. OBIEE - Where can I use a BI Server variable (session/repository) . Privacy Policy Automata, Data Type You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). The second case is where a session variable needs to be evaluated as a string. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. You should test the SQL statement using the Test button or a SQL tool such as the Oracle BI Client utility. 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. Required for authentication. The value of LOGLEVEL, a number between 0 and 5, determines the logging level that the Oracle BI Server uses for user queries. 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). Based on products assigned to user in security table, data filter is applied. Process (Thread) Lexical Parser Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. In the following example, the session variable RETAILERID has been assigned a numeric value. If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. You would initialize a session variable named Client, for example, that could be Choose Enable or Disable from the right-click menu. See Creating Initialization Blocks for more information. Function Is there any way to do this? Each instance of a session variable could be initialized to a different value. Contains the groups to which the user belongs. Data Type In the Variable Manager dialog, select Action > New > Session > Variable. repository. Does Cast a Spell make you a spellcaster? The next step is to associate variables with the initialization block. 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. Holds the value the user enters as his or her logon name. See "Creating Initialization Blocks" for more information. 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. For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. You can't use SQL to set your default initializer, that's why you only see Constants as an option. Data Type For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr Data Warehouse Visit our Welcome Center, Answers/Dashboards (Presentation Services). 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. 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.
