APAR status

  • Closed as program error.

Error description

  • When queues are deleted while a PCF inquireQueueNames
    command is executing, an FDC with Probe PC024010 is
    raised. When the number of queues is very big then the
    inquire queue names command takes longer to process and the
    chances of queues being deleted in this time frame increases.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This error would typically be seen by customers with a large
    number of queues, and a PCF program (likely a vendor program)
    which issues a PCF inquire queue names command.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The code which handles the PCF inquire queue names builds a
    list of matching names and then inquires upon the appropriate
    queue types. If a queue is deleted between its name being added
    to the list and the inquiry upon the queue type then the type
    is not resolved correctly and this error occurs.
    

Problem conclusion

  • Instead of building a list of names we now build a combined
    list of names and types, thus there's no chance of the queue
    being deleted between building the list and looking up the
    type.
