The next step is to establish execution precedence. This section provides information about working with session variables, and contains the following topics: Session variables are similar to dynamic repository variables in that they obtain their values from initialization blocks. You can then use this variable in a filter, as shown in the following WHERE clause: The variable LIST_OF_USERS contains a list of values, that is, one or more values. If you want the query for an initialization block to have database-specific SQL, you can select a database type for that query. When you use these variables for Oracle BI Presentation Services, preface their names with NQ_SESSION. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. The third case, dates, is the hardest. [nQSError: 23006] The session variable, NQ_SESSION.MyYear, has no value definition. This variable is typically populated from the LDAP profile of the user. Close the Variable Manager and save the repository. You must select a connection pool before typing an initialization string. Sharing Oracle BI Presentation Services cache entries is a way to minimize unnecessary communication with the Oracle BI Server. This is another system variable whose presence is always assumed when the USER system session variable is used. Data Persistence Contains the application roles to which the user belongs. (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).

See "Creating Repository Variables" or "Creating Session Variables" for information about creating variables. Quick question, a colleague of mine was telling me that the session variable, NQ_SESSION.GROUP, only shows groups which are assigned at the presentation >> level (or passed in from LDAP or other data source) but it does not show any of the group assignments made within the RPD itself. However, the cached results might not contain the most current session variable values. This variable has a value of Yes. The value of LOGLEVEL (a number between 0 and 5) determines the logging level that the Oracle BI Server uses for user queries. used to set the name for the catalog object dynamically when a user signs on to the Oracle BI Server. Computer You initialize dynamic repository variables in the same way as static variables, but the values are refreshed by data returned from queries. In the dashboard prompt, when chosing 'server variable' as default selection, only NQ_SESSION.STORENBR results in the default value being set. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services.

If every new session needs the most current set of session variables and their corresponding values, you should clear this option. 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 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. Dom Web Services You should test this SQL using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog. 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)? See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. 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. (Session init blocks only) Select the following options when appropriate: Disabled. It would be nice if there was a single place where you could say Id like dates to be formatted like this. But there isnt (a huge oversight, in my opinion), and if you attempt to descend into the javascript code forest to tweak things well, good luck. 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. Http Does Cosmic Background radiation transmit heat? Data (State) 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 RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". Data Warehouse Used to enable or disable Oracle BI Server plan cache seeding. Linear Algebra An initialization block contains the SQL statement that will be executed to initialize or refresh the variables associated with that block. This can reduce session startup time. Holds the value the user enters. User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. 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. 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. If you initialize a variable using a character string, enclose the string in single quotes ( ' ). Collection In the Variable Manager dialog, select Action > New > Session > Variable. In the Browse dialog, select the blocks that should be initialized before the block that you have open, and then click OK. To remove a block, in the [Repository|Session] Variable Initialization Block Execution Precedence dialog, select the block you want to remove and click Remove. Spatial Relation (Table) Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". Specifies the Catalog groups (Presentation Services groups) to which the user belongs, if any. Automata, Data Type The syntax is: WHERE COMPANYID=ValueOf(NQ_SESSION.RETAILERID). See "About Row-Wise Initialization" for more information. A repository variable has a single value at any point in time. Values can still be added to the multi-source session variable from other component initialization blocks that succeed in returning values. This value persists, and does not change until an administrator decides to change it. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. ':PASSWORD' (note the colon and the single quotes) is the password the user enters. Using the Multi-Source Session Variable in a Data Filter. Is there a limit on number of values session variable can hold. For session variable initialization blocks, you can select Row-wise initialization. The Variable Manager dialog has two panes. The Required for authentication option is dimmed, because this type of initialization block is executed after authentication. See <> for more information. Not the answer you're looking for? In the Application Role dialog, click Permissions. 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. To enable or disable an initialization block: In the Administration Tool, select Manage, then select Variables. You can also use this variable in a SQL statement. 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. Data Analysis I try to display the variable by define it in column formula as VALUEOF(NQ_SESSION. In previous releases, the Administration Tool did not limit the values of default initializers for static repository variables. It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). 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. Contains a description of the user, typically populated from the LDAP profile of the user.

Create a second session variable called MVCOUNTRY____ORCL, making sure to include four underscores between the variable name and the source name. For example, this option lets non-administrators to set this variable for sampling. 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. Distance In one of my report columns I need to get value of session variables like VALUEOF (NQ_SESSION.COLUMN1). Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Otherwise, the default initialization SQL for the database type is used. Linear Algebra 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 following example illustrates how to create and use a multi-source session variable: In the Variable Manager in the Administration Tool, select Action > New > Session > Initialization Block. Names for all variables should be unique. In this case, enclose the ValueOf function (including the name of the session variable) in single quotes. In the Variable dialog, type a name for the variable. You cannot use any other value or expression as the default initializer for a static repository variable. Data Science Versioning (Optional) Click Test to test the data source connectivity for the SQL statement. Exists only for compatibility with previous releases. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements, for example, figures such as GIF files. Right now I have @{biServer.variables['NQ_SESSION.TestVar1'] * biServer.variables[NQ_SESSION.TestVar3']} as the default value for a variable prompt. 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: A common use of these variables is to set filters for use in Oracle BI Presentation Services. There is no restriction on the number of values that the multi-source session variable can hold. When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. Dom Used to enable or disable Oracle BI Server plan cache seeding. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. There are two types of repository variables: static and dynamic. Don't forget the quotes which enclose the Variable Name. For example, I have declared and initialised 3 server variables: STORENBR SV_STORE_NBR storenbr In the Session Variable dialog, type a variable name. If you do not select a connection pool before typing the initialization string, you receive a message prompting you to select the connection pool. 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. Network 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". Using the Multi-Source Session Variable in a Logical Query. 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. 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. If you order a special airline meal (e.g. Session variables that are not needed during the session do not have their initialization blocks executed. Used for Oracle BI Presentation Services. In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password. This variable has a possible value of 0 or 1. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Computer You should test the SQL statement using the Test button or a SQL tool such as the Oracle BI Client utility. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements (for example, figures such as GIF files). Making statements based on opinion; back them up with references or personal experience. The USER value always matches the PROXY variable, that is the act as value. ':PASSWORD' (note the colon and single quotes) is the password the user enters. BETWEEN case when substr('valueof(NQ_SESSION. Graph 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. Connect and share knowledge within a single location that is structured and easy to search. Names for all variables should be unique. There are two types of session variables: system and nonsystem. Is there a more recent similar source? 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. 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. This variable has a value of Yes. Otherwise, in the Default initialization string box, type the SQL initialization string needed to populate the variables. Compiler For example, the NQ_SYSTEM initialization block is used to refresh system session variables. Each instance of a session variable could be initialized to a different value. For repository variables, you can specify the day, date, and time for the start date, as well as a refresh interval. Enable any user to set the value. However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server. Data Partition Please abide by the Oracle Community guidelines and refrain from posting any customer or personally identifiable information (PI/CI). [emailprotected] Distance In this case, the trusted internal process can connect regardless of whether the initialization block succeeds or fails. Contains the application roles to which the user belongs. When you select the Use OBI EE Server option for an initialization block: Execution precedence does not apply, because during user login, an initialization block with the Use OBI EE Server option selected is executed after initialization blocks with the Use OBI EE Server option not selected. ", Example message: "The execution of init block 'A_blk' cannot be deferred as it does not have a connection pool.". First, you open the block that you want to be executed last and then add the initialization blocks that you want to be executed before the block you have open.
