Environment Variables

Environment Variables

The database client path on a node is controlled by an environment variable.
Set the database client path environment variable for the PowerCenter Integration Service process if the PowerCenter Integration Service process requires a different database client than another PowerCenter Integration Service process that is running on the same node. For example, the service version of each PowerCenter Integration Service running on the node requires a different database client version. You can configure each PowerCenter Integration Service process to use a different value for the database client environment variable.
The database client code page on a node is usually controlled by an environment variable. For example, Oracle uses NLS_LANG, and IBM DB2 uses DB2CODEPAGE. All PowerCenter Integration Services and PowerCenter Repository Services that run on this node use the same environment variable. You can configure a PowerCenter Integration Service process to use a different value for the database client code page environment variable than the value set for the node.
You might want to configure the code page environment variable for a PowerCenter Integration Service process for the following reasons:
  • A PowerCenter Integration Service and PowerCenter Repository Service running on the node require different database client code pages. For example, you have a Shift-JIS repository that requires that the code page environment variable be set to Shift-JIS. However, the PowerCenter Integration Service reads from and writes to databases using the UTF-8 code page. The PowerCenter Integration Service requires that the code page environment variable be set to UTF-8.
    Set the environment variable on the node to Shift-JIS. Then add the environment variable to the PowerCenter Integration Service process properties and set the value to UTF-8.
  • Multiple PowerCenter Integration Services running on the node use different data movement modes. For example, you have one PowerCenter Integration Service running in Unicode mode and another running in ASCII mode on the same node. The PowerCenter Integration Service running in Unicode mode requires that the code page environment variable be set to UTF-8. For optimal performance, the PowerCenter Integration Service running in ASCII mode requires that the code page environment variable be set to 7-bit ASCII.
    Set the environment variable on the node to UTF-8. Then add the environment variable to the properties of the PowerCenter Integration Service process running in ASCII mode and set the value to 7-bit ASCII.
If the PowerCenter Integration Service uses operating system profiles, environment variables configured in the operating system profile override the environment variables set in the general properties for the PowerCenter Integration Service process.
