nq_session variables in obiee

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. Holds the Oracle BI Presentation Services user interface display language. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. 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. Click here to get started. Init block 'B_blk' does not have "Allowed deferred execution" flag set. 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. 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. Data Quality Connect and share knowledge within a single location that is structured and easy to search. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. "store number" = VALUEOF(NQ_SESSION. Data Quality If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). Because of this, do not put sensitive data like passwords in session or repository variables. Cryptography Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. The Oracle BI Server logs all SQL queries issued to retrieve session variable information if the logging level is set to 2 or higher in the Identity Manager User object, or the LOGLEVEL system session variable is set to 2 or higher in the Variable Manager. You can call a server variable by using this syntax : Data (State) 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. 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. Statistics 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. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. See "About Using Initialization Blocks with Variables" for more information. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Graph For example, an initialization block might use the function pi(), which is specific to SQL Server. In the Application Role dialog, click Permissions. Trigonometry, Modeling If you select this option, this initialization block must succeed for users to log in. An error will generate if a session variable is used in the opaque view. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. Data Persistence Data Partition The table contains three columns: USERID, containing values that represent the unique identifiers of the users, NAME, containing values that represent session variable names, VALUE, containing values that represent session variable values. The value of LOGLEVEL, a number between 0 and 5, determines the logging level that the Oracle BI Server uses for user queries. The repository variable, NQ_SESSION.MyYear, has no value definition. Debugging This section contains the following topics: The value of a static repository variable is initialized in the Variable dialog. See "Syntax and Usage Notes for SELECT_PHYSICAL" for more information. Note: The Test button is disabled when the Use OBI EE Server option is selected in offline mode. See "Examples of Initialization Strings" for examples. Cause had logged in as admin and i got back the value (get back number: 2) as I expected In the start_level column of the business layer i used the following script as source: INDEXCOL( VALUEOF(NQ_SESSION . Create an Agent with OBIEE Analytics Agents enable you to automate your business processes. Used to enable or disable Oracle BI Server result cache seeding. To view full details, sign in to My Oracle Support Community. 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 a semicolon must be included as part of a group name, precede the semicolon with a backslash character (\). Selector Static repository variables must have default initializers that are either numeric or character values. In the [Repository|Session] Variable Initialization Block dialog, type a name for the block. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. However, if you select Use OBI EE Server, the query is rewritten by the Oracle BI Server for the appropriate database. SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), #business-intelligence-suite-enterprise-edition-obiee. In the Variable Manager dialog, select Action > New > Repository > Variable. Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password. The Use caching option is automatically selected when you select the Row-wise initialization option. (The NQ_SYSTEM initialization block name is reserved.). Dimensional Modeling 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. Each query can refresh several variables: one variable for each column in the query. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. 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. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. For session variable initialization blocks, you can also select LDAP Server or Custom Authenticator. Identifies the query as a SELECT_PHYSICAL query. https://docs.oracle.com/cd/E28280_01/bi.1111/e10540/variables.htm#BIEMG3104 Share Improve this answer Follow This option prevents execution of all session variable initialization blocks during the session logon stage, giving a shorter logon time. 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. 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". 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. In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. Relational Modeling If these date prompts are setting report variables, you need to be able to deal with both formats. Legacy groups are mapped to application roles automatically. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. Log, Measure Levels 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. Custom Authenticator: For session variables. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". This variable has a possible value of 0 or 1. The next step is to associate variables with the initialization block. If a user is authenticated successfully, session variables can be used to set filters and permissions for that session. You can modify the value of the session variable with a dashboard prompt. Order For session variable initialization blocks, you can select Row-wise initialization. See "Testing Initialization Blocks" for more information. (Optional) Click Test to test the data source connectivity for the SQL statement. Html For static repository variables, the value you specify in the Default initializer window persists. variables is plural. This causes block A to execute according to block B's schedule, in addition to its own. 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. It contains the name that is displayed to the user in the greeting in the Oracle BI Presentation Services user interface. Grammar If the SQL statement contains an error, the database returns an error message. See "About Connection Pools for Initialization Blocks" for more information. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? Dimensional Modeling The second case is where a session variable needs to be evaluated as a string. The value is case-insensitive. To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. Data Persistence In the right pane, select the Application Roles tab, then double-click the application role for which you want to set data filters. Session variables are created and assigned a value when each user logs on. Security Sensitive. You can get this warning when you perform a check global consistency. Create a dashboard prompt with the following characteristics : Select only the column Calendar.Calendar Year. Then, you explicitly define session variables for each source. 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. Used to enable or disable Oracle BI Server plan cache hits. An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. 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. 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 values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog.
