APAR status

  • Closed as program error.

Error description

  • During the database activation there is an unnecessary call to
    open/lock/close DBM CFG cfg file for every DMS container, so
    systems having high number of tablespace/containers are
    impacted.
    The time required to access DBM CFG directly from the file can
    be significant, especially on MPP systems where the DBM CFG is
    NFS mounted. This problem results in longer time necessary to
    complete database activation process.
