Strategies for Maintaining PowerExchange Data

Strategies for Maintaining PowerExchange Data

PowerExchange lets you configure the locations of many of the PowerExchange data files and libraries. When you install and configure PowerExchange, Informatica recommends that you set up your environment to separate your data files and libraries from the PowerExchange software.
This approach to maintaining your PowerExchange data offers the following benefits:
  • Upgrading to a new PowerExchange version is easier.
  • Customized files do not get lost or overwritten during the upgrade.
  • Backing up PowerExchange data is easier.
Consider the following approaches when you set up your PowerExchange environment:
  • Create libraries for PowerExchange data that are separate from the PowerExchange software. Depending on the operating system and the data files, you might create the libraries yourself or specify their locations to the installation program.
    For example, on Linux, UNIX, or Windows, you can store configuration files in the parent directory of the installation directory, or in a separate directory.
  • Rename or copy configuration files and other files that you customize. For example, you can append the version number to the file name. In this way, you can easily identify the configuration files for a particular release. In addition, on some operating systems, this practice ensures that the installation program does not overwrite the configuration files.
After you set up your data, update the following items to point to the customized files:
  • Configuration parameters
  • Environment variables on Linux, UNIX, and Windows
  • DD statements in JCL for PowerExchange jobs and started tasks on z/OS
  • PowerExchange start commands in scripts or automation
The extent to which you can separate PowerExchange code and data, and the items that point to the data, varies by operating system.
