    LOAD SHRLEVEL CHANGE PARALLEL from a single input data set
    into a LOGGED table space abended with ABEND04E RC00E40347
    CAUSE=X'00E40318' because of a deadlock detection reported by
    
    -DSNT500I    DSNUGSAT - RESOURCE UNAVAILABLE
    REASON 00C90088
    TYPE 00000302
    
    The deadlock occurred between subtasks processing the reload
    phase when checking for duplicate keys during insert of records.
    
    The same problem can occur for LOAD SHRLEVEL CHANGE into a
    LOGGED table space for partition parallelism.

Problem conclusion

  • Modified LOAD processing to avoid the aforementioned deadlock
    issue for LOGGED table spaces.
