  • 1.  Db2 pureScale CF is restarted periodically because of the "CF process group file read but process group IDs are invalid" error

    Posted Mon May 08, 2023 04:59 PM

    Db2 11.1.4.6, AIX, 2 members + 2 CFs

    1 member and 1 CF are online only, if it matters.

    db2diag.log on CF:

    MESSAGE : CF process group file read but process group IDs are invalid -

    What's the reason of this error and how to resolve it?
