APAR status

  • Closed as program error.

Error description

  • When two wsadmin sessions are started concurrently in connect
    mode and connecting to the same DMGR, they may be assigned the
    same workspace.  This can cause various different exceptions
    to occur depending on where the two processes clash when doing
    work within the same workspace.
    

Local fix

  • Add a small wait to the time between starting up concurrent
    wsadmin sessions.
