What is the correct procedure to change the passwords for each of my IBM InfoSphere Information Server users (wasadmin, isadmin, xmeta, iadb)?
Answer
There is a specific sequence that should be followed.
First shutdown DataStage Services in the following order:
- Information Server
- Websphere Service
- DB2 Services

Perform the instructions below for each user, as required, if you are using Local OS authentication.

Open Computer Management
Open Db2Admin User
Change Password
Change the Password for all DB2 Services to reflect this new password
Open the DB2 Command Window and issue the following command:
>connect to xmeta user db2admin using <password>
Start DB2 Services
Start Websphere Service

xmeta
Open Computer Management
Open xmeta User
Change Password
Open command prompt and issue the following command:

wasadmin 
<After Metadata Workbench is installed>

BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file
