Problem conclusion

  • First fixed in DB2 version 9.7 Fix Pack 9.
    Starting from this version isolation level used by db2support
    tool can be specified via "-il" switch, which previously was
    applicable only to optimizer mode ("-st", "-sf").
    In order to avoid locking, db2support can be collected with
    uncommitted read (UR) isolation level, e.g.
    $ db2support . -d <db_name> -il UR
