How can I run the osh command of the InfoSphere Parallel Engine?

The osh command is the main program of the InfoSphere Parallel Engine. This command is used by DataStage to perform several different tasks including parallel job execution and dataset management. Normally, there is no need to run this command directly but sometimes it is useful to use it for troubleshooting purposes.

To run this command there are 3 environment variables that must be set. These are:

1. APT_ORCHHOME should point to Parallel Engine location
2. APT_CONFIG_FILE should point to a configuration file
3. LD_LIBRARY_PATH should include the path to the parallel engine libraries. Please note that the name of this environment variable may take a different name (such as LIBPATH in AIX or SLIB_PATH in HP-UX) depending on your Operating System. Note: This variable does not need to be set in Windows environments.
