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.

IS OBIEE 11G/FMW supported on VMware?

Virtualization or Raw Metal?

(Orginal link: http://blogs.oracle.com/proactivesupportEPM/entry/virtualization_or_raw_metal)

With the growing number of customers who want to run the Oracles EPM/BI (or other Fusion Middleware Software) in a virtualized environment, we face a growing number of people asking if running Oracle Software within VMware is supported or not.

Two KM articles reflect Oracles policy towards the use of VMware:
249212.1 and
1063937.1.

The bottom line is: you may use it at your own risk, but Oracle does not recommend it.

So far we have seen few problems with the use of VMware (other than performance and the usual limitations) but Oracle does not certify its software for the use in VMware (and specifically for RAC Software actively refuses any support) and any issue that may occur will be fixed for the native OS only.

It is on the customer to prove that the issue is NOT due to VMware in case that an issue is encountered.

See: “Oracle Fusion Middleware Supported System Configurations page

And also
