Reporting Capabilities in Oracle BICS with respect to OBIEE 11g

In today’s technological landscape there’s an ever-accelerating demand for increased efficiency and effectiveness. As organizations evaluate new solutions, they must consider the effective end-user adoption of every technology prior to implementation, particularly as the cost of deployment and training are often driven by the rate of user adoption. So every organization requires a careful evaluation of the tool, as well as its potential for end-user adoption.

To enable all users to tap into the most pertinent data, whenever and wherever they need it, Oracle has introduced, Oracle BI Cloud Service. The new Oracle BI CS is familiar with the users of OBIEE 11g. In some areas, Oracle BICS provides nearly identical features and functionality to Oracle BI EE. These similarities enable users to become more productive more quickly using Oracle BI Cloud Service. That said, you don’t need any special skills/training, just your current OBIEE analyzing and visualizing hands on skills are enough to adopt this new BICS.

What’s new?

Oracle BICS is designed with a fresh, lighter weight UI by integrating a new style called Skyros. It is exciting to see how quickly oracle is enhancing BI capabilities and visualizations components that provide significant graphical and tabular capabilities for analyzing data. In that direction, Oracle BI CS is being modernized and introduced following new features/components (in this V1 release).

Treemap view

Treemaps organize hierarchical data by grouping the data into rectangles (known as tiles). Treemaps display tiles based on the size of one measure and the color of the second measure.

The following figure shows an example of simple treemap view.
It shows the rectangles space filled with the “Size” and “Color” proportional to the “#Leads” across different Lead Sources.

By default, the first measure of the analysis in the Criteria tab is selected as the Size By measure, and the second measure is selected as the Color By measure. If there is only one measure in the analysis, this measure is the default for both Size By and Color By options. Additionally, the Style element defaults to Percentile Binning with “quartile” as the value for the number of bins.

Treemap view has the following characteristics:

  • Tiles are colored by percentile binning or continuous color fill.
  • First Group By dimension is displayed as the group (header) label.
  • The order of the Group By dimensions implies the nesting order within the treemap. The last dimension in the Group By is the lowest level and this dimension name is displayed as the tile label. If the label is too long to fit on the tile, then it is truncated. Full values for the labels display in the tooltip.

Global Variables

In addition to session, Presentation and Request variables, BICS introduces a new variable called Global Variables. A global variable is a column created by combining a specific data type with a value. The value can be a Date, Date and Time, Number, Text, and Time.

You create a global value during the process of creating an analysis by using the Edit Column Formula dialog. The global variable is then saved in the catalog and made available to all other analyses within a specific tenant system.

The global variable is evaluated at the time the analysis is executed, and the value of the global variable is substituted appropriately.

Syntax for calling Global Variables in BICS Analysis:

                                   @{global.variables.variablename}

where variablename is the name of the global variable, for example, gv_region. When referencing a global variable, you must use the fully qualified name as indicated in the example.

For example: @{global.variables.gv_txt_multiply_rev}

Note: Only users with the “BIAdvancedContentAuthor” role can manage (add, edit, and delete) global variables.

Upgrade Old nested folders using the Convert Presentation Folders Utility in OBIEE 11.1.1.7.0 RPD

Starting in Release 11.1.1.6.2, you can designate child presentation tables using the Child Presentation Tables tab in the Presentation Table dialog to give the appearance of nested folders in Answers and BI Composer. However, in previous releases, repository developers could achieve one level of nesting in Answers by adding a hyphen at the beginning of a presentation table name, or by adding an arrow (->) at the beginning of a presentation table description.

For e.g.: In previous versions, if you wanted to move the “more Time Objects” to the table/folder, then we will place the ‘->’ in description as shown below.

Convert to Nested folders

If you used these methods to achieve nesting, it is recommended that you run the Convert Presentation Folders utility to convert your metadata to the new structure.

Note:

Achieving nesting by adding hyphens at the beginning of presentation table names or adding arrows at the beginning of presentation table descriptions is deprecated for this release and will be removed in a future release.

To use the Convert Presentation Folders utility:

  1. Open your repository in the Administration Tool in offline mode.

Note: Do not run the Convert Presentation Folders utility in online mode.

  1. Select Tools, and then select Utilities.
  2. Select Convert Presentation Folders and click Execute.

The hyphens and arrows disappear from presentation table names and descriptions, and the affected tables are listed as child tables for the appropriate parent object.

Once you converted, the above example will be converted to the new definition as follows:

Convert to Nested folders2

There are no limits on nested folders depth. For more information on nested folders, visit https://shivabizint.wordpress.com/2012/06/01/sub-folders-nesting-folders-in-obiee-11g-answers/

How to bypass Presentation Server Cache in OBIEE 11G

During our development if we wanted to check the report level UI changes, sometimes we will not see the changes immidiately. This is due to Presentation Server Cache. Eventhough we disable the BI Server cache, It doesnt make any effect on presentation Server objects.

So in that situations we need to disable Presentation server cache permanently across OBI Application, To do this add the following parameters in instaceconfig.xml. (Make sure that you have taken a backup copy of instanceconfig.xml)

<ServerInstance>
———

<Cursors>
<ForceRefresh>true</ForceRefresh>
</Cursors>

——–

</ServerInstance>

Now restart the OBI Presentation server service and test the results.

Note: Keep in mind that this parameters cause Presentation Server to always bypass its cache. To be used only for testing – may have serious performance implications.

Keep smiling 🙂

Thanks,
Shiva

OBIEE 11G – Important Security Considerations (SSL) if using external LoadBalancer

In OBIEE enterprise topology, make sure the external load balancer used should be able to terminate SSL requests at the load balancer and forward traffic to the back-end real servers using the equivalent non-SSL protocol (for example, HTTPS to HTTP).

For security purposes, and because the load balancer terminates SSL requests (Oracle HTTP Server routes the requests as non-SSL to WebLogic Server), after SSL is configured for the load balancer, turn on the WebLogic Plugin Enabled flag for the domain. To do this, follow these steps:

1. Log in to the Administration Console.
2. Click the domain name in the navigation tree on the left.
3. Click the Web Applications tab.
4. In the Change Center, click Lock & Edit.
5. Select WebLogic Plugin Enabled.
6. Click Save, then click Activate Changes.
7. Restart the Administration Server and Managed Server.

Tip: WebLogic Plugin Enabled: Specifies whether or not the proprietary WL-Proxy-Client-IP header should be honored. (This is needed only when WebLogic plugins are configured.)

In additon to above, make sure Oracle HTTP Server (OHS) to add the following SSL directives in each <location> section to the ORACLE_BASE/admin/instance_name/config/OHS/component_name/mod_wl_ohs.conf file:

WLProxySSL ON

WLProxySSLPassThrough ON

Tips: Set WLProxySSL parameter to ON to maintain SSL communication between the plug-in and WebLogic Server when the following conditions exist:

An HTTP client request specifies the HTTPS protocol
The request is passed through one or more proxy servers (including the WebLogic Server proxy plug-ins)
The connection between the plug-in and WebLogic Server uses the HTTP protocol
When WLProxySSL is set to ON, the location header returned to the client from WebLogic Server specifies the HTTPS protocol.

Things to remember for OBIEE 11G on Microsoft SQL Server

The basic things to remember when configuring OBIEE 11G on Microsoft SQL Server:

1. While running RCU:

  • Use case-sensitive collation in order that the database can reflect any case-sensitivity in your repository naming conventions.
    Run this sql command: ALTER DATABASE OBI COLLATE Latin1_General_CS_AS 
    (This command is for UK English installation, for US locale installation use Latin1_General_CP1_CS_AS)
  • Activate the mechanism of row versioning, so it`s require to enable Read Commit Snapshot.
    Run this command: ALTER DATABASE OBI SET READ_COMMITTED_SNAPSHOT ON

2. When configuring OBIEE 11G Scheduler with MS SQL server:

When installed with a Microsoft SQL Server 2005/2008 database, the Oracle Business Intelligence installer configures Oracle BI Scheduler with a SQL Server 2005/2008 driver. If multibyte data is used, scheduled jobs might fail. To avoid this issue, use Oracle Enterprise Manager to configure the Oracle Business Intelligence system to use a SQL Server 7.0/2000 driver instead.

To configure Oracle BI Scheduler to use the SQL Server 7.0/2000 driver with Microsoft SQL Server 2005/2008:

  1. After you install Oracle Business Intelligence, log into the system through Oracle Enterprise Manager.
  2. Navigate to the Scheduler tab for the Oracle Business Intelligence server.
  3. Click Lock and Edit Configuration.
  4. Click the Database drop-down list and select SQL Server 7.0/2000.
  5. Click Apply.

3. When configuring OBI Publisher 11G Scheduler with MS SQL server:

Prerequisite: Ensure that the Microsoft SQL Server is set up with mixed mode authentication. Also ensure that the user that you enter to configure the scheduler has the “db_owner” role.

The below table describes the fields for the DataDirect driver to connect to a Microsoft SQL Server 2000 or 2005 database.

DataDirect Driver Fields for SQL Server Databases

Field Entry
Database Type: Select Microsoft SQL Server 2000 or Microsoft SQL Server 2005 from the list.
Connection String: Enter the following connection string parameters: jdbc:hyperion:sqlserver://<hostname>:<port>;DatabaseName=<DATABASENAME> For example: jdbc:hyperion:sqlserver:// mydatabaseserver.com:1433;DatabaseName=bipscheduler
Database Driver Class: hyperion.jdbc.sqlserver.SQLServerDriver

4. in RPD Development:

  • When you are creating DSN for SQL Server, use sql server native client 10.0 instead of any other drivers. From Sql server 2008 onward, it is strongly recommended even some documents says dont use ODBC native drivers.
  • In RPD, the Query DBMS for SQL server in 11.1.1.6 only work when you specify the DSN name directly (by default it comes with OLAP_DSN session variable).
  • If you have a column with UNIQUEIDENTIFIER as its data type in MS SQL server, then change that column datatype to BINARY(16) or VARCHAR(40) in OBI RPD Physical layer.

5. Performance Tuning:

The following guidelines pertain to performance tuning parameters for Microsoft SQL Server databases. For more information about these parameters, see your Microsoft SQL Server documentation.

  • Store tempdb on a fast I/O device.
  • Increase the recovery interval if perfmon shows an increase in I/O.
  • Use an I/O block size larger than 2 KB.

Thanks,
Shiva
