Changing IMS passwords

To protect DBCTL against unauthorized /LOCK and /UNLOCK commands for certain PSBs (referred to as "programs" in the IMS™ publications) and databases, you can establish IMS passwords for those PSBs and databases.

IMS passwords are defined by the security maintenance utility or the /CHANGE command with the PASSWORD keyword. (See Security checking with DBCTL for a description of DBCTL password security.) Using the /CHANGE command with the PASSWORD keyword changes the password immediately.

To add a password security definition, use the PASSWORD keyword with the /MODIFY PREPARE command. To request that password security specifications should take effect when restart processing has completed, use the PASSWORD keyword with the /NRESTART command.
