06102: IMS Data Base Open

    FILE:            IMS System Incident
    SAS FILE NAME:   DETAIL.IMSINC01
    SOURCE LOCATION: sharedprefix.MICS.SOURCE(DYIMSEXC)

    SEVERITY:        Warning       (SEVERITY='W')
    MANAGEMENT AREA: Performance   (MGMTAREA='PERFORMANCE')

    PURPOSE:  Identifies an OS open of an IMS data base.

    RATIONALE:  Data Base Opens can lead to sporadic
performance problems as the requestor must wait for the OS
open process to complete.  Ideally, a data base should be
opened only once per execution of the IMS Control Region.
Frequent Data Base Opens and Closes may indicate
insufficiency in the DMB pool size.

    DEFINITION:  This exception is detected when IMS detects
