The Change MIMIXOWN User Profile (CHGMMXPRF) command calls IBM commands to change the password for the MIMIXOWN user profile and its associated TCP server authentication entries on the local system. The MIMIXOWN user profile is also set to *SIGNOFF for initial menu (INLMNU), and *ENABLED for status (STATUS).
Use this command on systems that have one or more products that use the MIMIXOWN user profile or that have multiple instances of a product installed. The user profile password must be the same on all systems where MIMIX is installed.
To allow this command to complete successfully, you must have sufficient authority to run the IBM commands CHGUSRPRF and CHGSRVAUTE.
Updating the MIMIXOWN password and authentication entries
Use the CHGMMXPRF command to change the MIMIXOWN password and update existing authentication entries. The password is case-sensitive and must be identical across all systems in the MIMIX network to prevent security errors (LVE0127).
You can update the password using one of the following methods:
- Run CHGMMXPRF locally on each system by using SYSTEM(*LOCAL).
- Use SYSTEM(*INST) with the INSTLIB parameter to update across nodes of the instance.
- Explicitly specify all system hostnames or addresses with the SYSTEM parameter (recommended for multiple MIMIX environments).
