Changing passwords for service tools user IDs
You have various ways to change the passwords for service tools user IDs. You can use dedicated service tools (DST), system service tools (SST), the Change Service Tools User ID (QSYCHGDS) API, or the Change SST User (CHGSSTUSR) command.
You should have already configured service tools user IDs and you might want to review the recommendations for managing service tools user IDs before changing any existing service tools user IDs and passwords.
Attention: If you lose or forget the passwords
for all security officer profiles and all security service tools user IDs,
you might need to install and initialize your system from the distribution
media to recover them. For this reason, it is suggested that you create multiple
profiles and user IDs. Contact your service provider for assistance.
