Abstract

OSP-PERFM ENDPEX DTAOPT(*MGTCOL) POOR PERFORMANCE

Error Description

There is poor performance when saving PEX data into a *MGTCOL  
object.                                                        

Problem Summary

Performance Explorer supports saving data to a Management      
Collection Object via ENDPEX DTAOPT(*MGTCOL).                  
However, saving small PEX *TRACE collections takes an excessive
amount of time.  About 60 seconds are spent doing apparently    
nothing before status messages start appearing.  This problem  
does not occur when doing ENDPEX DTAOPT(*MGTCOL) on a *STATS or
*PROFILE collection.                                            

Problem Conclusion

ENDPEX was using the Management Collection Object code to open a
repository to save data related to the PEX *TRACE collection.  
The Management Collection Object code attempted to get a lock on
the *MGTCOL but had to wait because there was already a lock on
the object.    The Management Collection Object code has been  
changed so that it is not necessary to obtain a lock on the    
object.
