To create a new initialization block, click New. Oracle BI, (Apart from the obvious answer: it's a bug. For example, this option lets non-administrators to set this variable for sampling. When the user modifies the date range using the first calendar, the format of the first date changes. This variable has a possible value of 0 or 1. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. It's meant to be a constant value. When a user begins a session, the Oracle BI Server creates new instances of session variables and initializes them. Trigonometry, Modeling The format for the session variable names must be: where the separator must be exactly four underscore characters. When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. If these date prompts are setting report variables, you need to be able to deal with both formats. In the left pane, select Initialization Blocks under Repository or Session, depending on whether you want to enable or disable repository initialization blocks or session initialization blocks. Computer (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. Enter a title that clearly identifies the subject of your question. You use the same procedure to define nonsystem session variables as for system session variables. In the Variable Manager dialog, select Action > New > Session > Variable. Text 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. The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). Distance Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). Otherwise, in the Default initialization string box, type the SQL initialization string needed to populate the variables. If the SQL statement contains an error, the database returns an error message. 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. System session variables are session variables that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes. Data Persistence Repository variables and system and nonsystem session variables are represented by a question mark icon. "ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." For example, you have Monitoring Each instance of a session variable could be initialized to a different value. Contains the global unique identifier (GUID) 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 Presentation Services. In the Session Variable dialog, type a variable name. You should test the SQL statement using the Test button or a SQL tool such as the Oracle BI Client utility. Is there a more recent similar source? Table 19-2 Sample Session Variables Database Table. The values remain unchanged for the duration of the session. New to My Oracle Support Community? The SQL statement used to refresh the variable must reference physical tables that can be accessed through the connection pool specified in the Connection Pool field. Lexical Parser Determines if the initialization blocks required for authentication are executed. Click Link to associate an existing variable with an initialization block. 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 Variable Manager dialog, double-click the last initialization block that you want to be initialized. For example, to filter a column on the value of the dynamic repository variable CurrentMonth, set the filter to the variable CurrentMonth. Privacy Policy Holds the value the user enters as his or her logon name. Data Processing 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. ':PASSWORD' (note the colon and the single quotes) is the password the user enters. It will not change unless you change it. Data Persistence The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. If you select Database as the data source type for an initialization block, the values returned by the database for the columns in your SQL statement are assigned to variables that you associate with the initialization block. Cryptography 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. The order of the columns in the SQL statement and the order of the variables associated with the initialization block determine which columns are assigned to each variable. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. Trigonometry, Modeling 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. Graph There are two types of session variables: system and nonsystem. 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. Security Used for Oracle BI Presentation Services. To add a Default Initializer value, type the value in the Default Initializer box, or click the Expression Builder button to use Expression Builder. 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. If there are more variables than columns, the additional variables are not refreshed (they retain their original values, whatever they may be). In other words, users are denied access to Oracle Business Intelligence if the initialization block fails to execute. 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. There is no restriction on the number of values that the multi-source session variable can hold. Collection Dates are, frankly, inordinately messy in OBIEE. When a user belongs to multiple roles, include the role names in the same column, separated by semicolons,for example, RoleA;RoleB;RoleC. This system session variable overrides a variable defined in the Users object in the Administration Tool. 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. Database: For repository and session variables. 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. In the Session Variable dialog, type a variable name. I have created variables with the same name using row vise initialization. Relational Modeling The multi-source session variable will fail only if all of the component initialization blocks return null values. In the following example, the session variable RETAILERID has been assigned a numeric value. 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. Any users with the same nonblank request key share the same Oracle BI Presentation Services cache entries. Data Science This variable has a possible value of 0 or 1. OBIEE offer several variables which can be set : variables from the OBIEE Server known as session and repository variables. variables is plural. Color When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. 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. Process (Thread) Ratio, Code 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 this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. 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. See "Examples of Initialization Strings" for examples. The values of dynamic repository variables are set by queries defined in the Default initialization string field of the Initialization Block dialog. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). StartDate)', 1, 3) = '201' then to_date(substr('valueof(NQ_SESSION.StartDate)',1,10), 'yyyy-mm-dd')else to_date('valueof(NQ_SESSION.StartDate)', 'mm/dd/yyyy') end AND case when substr('valueof(NQ_SESSION.EndDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION.EndDate)', 1, 3) = '201' then to_date(substr('valueof(NQ_SESSION.EndDate)',1,10), 'yyyy-mm-dd')else to_date('valueof(NQ_SESSION.EndDate)', 'mm/dd/yyyy') end, Tags: Because of this, do not put sensitive data like passwords in session or repository variables. Compiler used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. 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. Why is the error occurring only for User B? For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. 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. Data Type Number For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. This variable has a possible value of 0 or 1. Contains the global unique identifiers (GUIDs) for the application roles to which the user belongs. To create a new initialization block, click New. [nQSError: 23006] The session variable, NQ_SESSION.MyYear, has no value definition. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. For example, here are dates as set by the default values in the prompt. 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. You should set the logging level to 2 for the administrator to provide the most useful level of information. This is another system variable whose presence is always assumed when the USER system session variable is used. Only repository variables can be used in the definition.

If you are using a calendar thats different from the normal Gregorian calendar (i.e. 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. You cannot use variables to represent columns or other repository objects. Dom 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. Selector Dynamic repository variables are useful for defining the content of logical table sources. See "Creating Initialization Blocks" for more information. Thanks for contributing an answer to Stack Overflow! Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. Does Cosmic Background radiation transmit heat? This chapter describes how to use variables in the Oracle BI repository to streamline administrative tasks and dynamically modify metadata content to adjust to a changing data environment. Data Visualization Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'A' which is security sensitive.". Used to enable or disable Oracle BI Server plan cache seeding. In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. [emailprotected] Close the Variable Manager and save the repository. If there are fewer variables than columns, extra column values are ignored. For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr Data Processing You can also right-click an existing initialization block in the Variable Manager and choose Disable or Enable. With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. 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)? And when i try a system session variable VALUEOF(NQ_SESSION. Session variables are created and assigned a value when each user logs on. 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. You cannot use any other value or expression as the default initializer for a static repository variable. 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.
