";s:4:"text";s:26956:"Then, you explicitly define session variables for each source. When you check in the initialization block, the value of the dynamic variables is reset to the values shown in the Default initializer. The USER value always matches the PROXY variable, that is the act as value. Grammar To learn more, see our tips on writing great answers. The variables receive their values from the initialization string that you type in the Initialization Block dialog. In the Application Role dialog, click Permissions. Privacy Policy Infra As Code, Web In addition, if an initialization block fails for a particular connection pool during Oracle BI Server start-up, no more initialization blocks using that connection pool are processed. Click Edit Data Source next to the Connection Pool field. The user can alter some elements of the user interface by picking a style when logged on to Oracle BI Presentation Services. I need to create a Dashboard, where I can fill out one Dashboard prompt and set some request variables, and then have the default values in another dashboard prompt, or the prompt for an analysis be based on the variables set in the first prompt. Data Quality In the Session Variable dialog, type a variable name. The Oracle BI Server can also provide functions (such as PI) that might not be available in the data source, and the SQL statement will work with other data sources supported by the Oracle BI Server (for example, ADF, SQL Server, Oracle, and XML files). Ratio, Code 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. See Oracle Fusion Middleware Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. If you can get to set a number request variable because it always add quotes, it's a bug because the value is independent from the data type of your presentation variable (works for the version 10.3.4.1). 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 the Session Variable dialog, type a variable name. Select the type of variable: Static or Dynamic. Web Services There are two types of session variables: system and nonsystem. https://docs.oracle.com/cd/E28280_01/bi.1111/e10540/variables.htm#BIEMG3104 Share Improve this answer Follow 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. You can use the Variable Manager in the Administration Tool to define variables. It is also saved as the author field for catalog objects. You can then use the SQL IN operator to test for values in a specified list. The values remain unchanged for the duration of the session. If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. repository. By default, when you open the Initialization Block dialog for editing in online mode, the initialization block object is automatically checked out. You can also use this variable in a SQL statement. The new value is only valuable for the query. See "About Row-Wise Initialization" for more information. 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. Relation (Table) Relational Modeling The repository variable, NQ_SESSION.MyYear, has no value definition. Used for Oracle BI Presentation Services. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. 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). See Security Guide for Oracle Business Intelligence Enterprise Edition for more information about the PROXY system session variable. 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. For example, this option lets non-administrators to set this variable for sampling. 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. Don't have a My Oracle Support Community account? See Creating Initialization Blocks for more information. 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. NQ_SESSION.ROLES is a session variable that returns a semicolon delimited string of roles assigned to the . To add a Default initializer value, type the value in the Default initializer box, or click the Expression Builder button to use Expression Builder. GUIDs for application roles are the same as the application role names. StartDate)', 1, 3) = '200' or substr('valueof(NQ_SESSION. Process (Thread) Security Sensitive. 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. Javascript In the [Repository|Session] Variable Initialization Block dialog, click Edit Execution Precedence. The Required for authentication option is dimmed, because this type of initialization block is executed after authentication. To test initialization blocks (optional): In the Variable Manager dialog, double-click the initialization block. Data Persistence [nQSError: 23006] The session variable, NQ_SESSION.user, has no value definition. This article gives an How-to : OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? 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. It's meant to be a constant value. You would initialize a session variable named Client, for example, that could be To create a multi-source session variable, you first create row-wise initialization blocks for each source. The deferred execution of an initialization block also triggers the execution of all unexecuted predecessor initialization blocks. This variable is typically populated from the LDAP profile of the user. This chapter contains the following topics: Working with Multi-Source Session Variables. If these date prompts are setting report variables, you need to be able to deal with both formats. Used to enable or disable Oracle BI Server result cache hits. For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. The other two can not be addressed it seems, I have tried variations: The same goes for default selection type 'variable expression': the expected result is achieved when using @{biServer.variables['NQ_SESSION.STORENBR']}, yet no such luck using: @{biServer.variables['NQ_SESSION.SV_STORE_NBR']}, @{biServer.variables['NQ_SESSION. (Repository initialization blocks only) In the Schedule area, select a start date and time and the refresh interval. Failure to execute can occur if the wrong credentials have been defined in the initialization block, or if there is an error in the default initialization string. Monitoring You should set the logging level to 2 for the administrator to provide the most useful level of information. If you select Database as the data source type, and select the Use OBI EE Server option. Create a row-wise initialization block called mvcountry_sebl_init with the following SQL for Default initialization string: Create a second row-wise initialization block called mvcountry_orcl_init with the following SQL for Default initialization string: Still in the Variable Manager, select Action > New > Session > Variable. For example, you have Trigonometry, Modeling User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. This variable has a possible value of 0 or 1. Static repository variables must have default initializers that are constant values. 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. To create a new initialization block, click New. Used for Oracle BI Presentation Services. Html You must select a connection pool before typing an initialization string. SELECT DISTINCT 'PRODUCT', product_id FROM BI_SECURITY WHERE UPPER(USER_ID) = UPPER(':USER'), #business-intelligence-suite-enterprise-edition-obiee. This section explains how to create session variables. The Variable Manager dialog has two panes. Why is the error occurring only for User B? Nominal Learn about session variables and how to create them. OBIEE - How to set and use a server variable (system/repository) of type date ? Kurt Wolff, vegan) just to try it, does this inconvenience the caterers and staff? For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. There is no restriction on the number of values that the multi-source session variable can hold. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set. Compiler While the initialization block is checked out, the Oracle BI Server may continue to refresh the value of dynamic variables refreshed by this initialization block, depending on the refresh intervals that are set. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. Because of this, do not put sensitive data like passwords in session or repository variables. Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. Does Cast a Spell make you a spellcaster? Table 19-2 shows the table in this example. In the Administration Tool, select Manage, then select Variables. Data Type Contains the locale of the user, typically populated from the LDAP profile of the user.

You use the same procedure to define nonsystem session variables as for system session variables. For information about using session variables when setting up security, see Managing Session Variables in Security Guide for Oracle Business Intelligence Enterprise Edition. 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. 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. Used to enable or disable Oracle BI Server subrequest cache hits and seeding. For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. See "Examples of Initialization Strings" for additional examples. ), #business-intelligence-suite-enterprise-edition-obiee. Otherwise, in the Default initialization string box, type the SQL initialization string needed to populate the variables. Distance It is also saved as the author field for catalog objects. With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. When a user belongs to multiple groups, include the group names in the same column, separated by semicolons (for example, GroupA;GroupB;GroupC). The initialization block is used to set your session variable to a dynamic value. Linear Algebra For the syntax, add NQ_SESSION if the variable is a session variable and see the relevant section for the function call. To see the value of the server variable, I have had a text box dashboard below the dashboard prompt with this code : Then when you set for instance the dashboard prompt to 1996 and hit the go button, you will retrieve this result : The value of the repository session variable is not changed. Find centralized, trusted content and collaborate around the technologies you use most. If the SQL statement contains an error, the database returns an error message. 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 Required for authentication option is selected in the Session Variable Initialization Block dialog. See "About Using Initialization Blocks with Variables" for more information. You cannot use any other value or expression as the default initializer for a static repository variable. There are a plethora of ways that dates can get formatted depending on which application is being used to select the dates. As with dynamic repository variables, session variables obtain their values from initialization blocks. Design Pattern, Infrastructure [emailprotected] The next step is to associate variables with the initialization block. Select this option to set session variables after the initialization block has populated the value (at user login) by calling the ODBC stored procedure NQSSetSessionValue(). I am confused on how to use the non-system session variable in Answers, says, in column formula, in a filter and in title view. To view full details, sign in to My Oracle Support Community. 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.

Contains the permissions held by the user, such as oracle.bi.server.manageRepositories. Legacy groups are mapped to application roles automatically. Each instance of a session variable could be initialized to a different value. In the View Data from Table dialog, type the number of rows and the starting row for your query, and then click Query. The order of the columns in the SQL statement and order of the variables associated with the initialization block determine the column value that is assigned to each variable. It is often convenient to set a number of session variables to capture date values that you use repeatedly in your queries. How can I explain to my manager that a project he wishes to undertake cannot be performed by the team? 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. For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. System session variables are session variables that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes. You need to describe the content of these sources on the Content tab of the Logical Table Source dialog. Exists only for compatibility with previous releases. 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. In RPD, I created a new init block with session variable PRODUCT and row wise initialization is set. The Oracle BI Server substitutes the value of the repository variable for the variable itself in the metadata. Data Structure "storenbr"), What am I missing? Example message: "The execution of init block 'A_blk' cannot be deferred as it is using row-wise initialization.". Cryptography Is there any way to do this? Data Processing See "When Execution of Session Variable Initialization Blocks Cannot Be Deferred" for more information. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. 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. What are some tools or methods I can purchase to trace a water leak? Click OK to return to the Initialization Block dialog. Logical Data Modeling The intent is to filter that data just for that retailer. The Use caching option is automatically selected when you select the Row-wise initialization option. The tables do not have to be included in the Physical layer of the metadata. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. COMPANYID is the name of a physical column. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. Holds the value the user enters as his or her logon name. variables is good where variable is bad. At run time, if an initialization string for the database type has been defined, this string is used. 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. To create a session variable: In the Administration Tool, select Manage, then select Variables. Not correct. The third case, dates, is the hardest. It is recommended that you create a dedicated connection pool for initialization blocks where you select Database as the data source type. DataBase Asking for help, clarification, or responding to other answers. Process Data Partition Ive done it this way. I am seeing a strange issue when using SESSION variable in OBIEE 11g RPD for data level security. Browser It identifies the default dashboard the user sees when logging in (the user can override this preference after logged on). The names of system session variables are reserved and cannot be used for other types of variables. Select Row-wise initialization. To enable or disable an initialization block: In the Administration Tool, select Manage, then select Variables. See "Testing Initialization Blocks" for more information. See "Creating Initialization Blocks" for more information. Only repository variables can be used in the definition. 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 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 S of Server must be in uppercase. 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. Cache hits would only occur on cache entries that included and matched all security-sensitive variables. Data Concurrency, Data Science Such directories begin with sk_. Why must a product of symmetric random variables be symmetric? Initializing Dynamic Repository Variables. WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). OBIEE - BI Server Patch (automatic update with a patch file) Spatial See "Setting Administration Tool Options" for more information. Data Analysis For example, to filter a column on the value of the variable LOGLEVEL, set the filter to the variable NQ_SESSION.LOGLEVEL. This variable has a value of Yes. Mathematics Unlike dynamic repository variables, session variables are not updated at scheduled time intervals. This variable has a possible value of 0 or 1. OBIEE - BI Server Variables (session and repository). 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 .

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: 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. Names for all variables should be unique. 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. Operating System Number If you select Row-wise initialization, the Use caching option becomes available. 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. Time biServer is good where biserver is not good. 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 can only test this SQL statement using the Test button in the [Repository|Session] Variable Initialization Block Data Source dialog when in online mode. 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. Used to enable or disable Oracle BI Server plan cache hits. 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. 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. Function 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. 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). Http In online mode, Initialization Block tests do not work with connection pools set to use :USER and :PASSWORD as the user name and password. Privacy Policy The query returns data only if the user ID and password match values found in the specified table. Spatial In the Variable Manager dialog, select Action > New > Session > Variable. Web Services "SV_STORE_NBR"']}, @{biServer.variables['NQ_SESSION.storenbr']}, @{biServer.variables['NQ_SESSION."storenbr"']}. 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. Data Structure Using the Multi-Source Session Variable in a Data Filter. Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. In the Variable Manager dialog, select Action > New > Session > Variable. You can edit repository initialization blocks, or session initialization blocks. Select a discussion category from the picklist. When you have create a server variable, you have to reference it. Http 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. In the [Repository|Session] Variable Initialization Block Execution Precedence dialog, click Add. A common use for nonsystem session variables is setting user filters. Infra As Code, Web Custom Authenticator: For session variables. Determines if the initialization blocks required for authentication are executed. However, it will still work with other data sources because the SQL statement is processed by the Oracle BI Server.
