Defining your environment

The /etc/profile file, /etc/environment file, and .profile file contain variables that specify the environment on your system.

About this task

  • Define environment variables in the /etc/profile to set defaults for all users on a system.
  • Define environment variables in the /etc/environment to specify the basic environment for all processes.
  • Define environment variables in the .profile file to customize the working environment for an individual user ID.

You need to set environment variables if you will run replication and Event Publishing programs from a USS command session, a BPXBATCH job, or from the Replication Center. See Example environment setup for replication and publishing on z/OS for a complete definition that you can use in your /etc/profile or .profile files.
