Error description

  • In Db2 11.1 Mod 3 Fix Pack 3 and in special build based on Db2
    11.1 Mod 3 Fix Pack 3 the db2support tool
    (a problem analysis and environment collection utility)
    in certain circumstances can erroneously remove critical
    database files, resulting in a database corruption or an
    instance-wide outage.
    
    This issue may affect customers running Db2 11.3 Mod 3 Fix Pack
    3 or special build based on Db2 11.1 Mod 3 Fix Pack 3 on all
    platforms
    
    This issue happens when the length of the output path specified
    for db2support is not sufficiently longer than the length of the
    instance name.
    
    To safely workaround this issue, specify a fully-qualified
    db2support output path when you run db2support:
    
        db2support <output-path>
    
    with the length of output-path longer than instance-name + 9,
    where "instance-name" is the short instance name (e.g.
    "db2inst1").
