Abstract

OSP-OTHER-F/QMYSE-T/QMYSE-MSGMCH3402 MYSQL QUERY GENERATES 2021
ERROR

Error Description

OSP-OTHER-F/QMYSE-T/QMYSE-MSGMCH3402 MySQL query generates 2021
error                                                          

Problem Summary

MySQL or other QmyProcessRequest API client programs using      
multiple connections may encounter 2021 errors and MCH3402      
messages to/from QMYSE when performing an API operation. This is
most likely to happen under heavy load, when multiple new      
connections are being established simultaneously.              

Problem Conclusion

When multiple connections are simultaneously established,      
internal structures used to associate QSQSRVR jobs may be      
incorrectly updated. This may lead to a variety of error        
conditions including query failures with MCH3402 messages and  
extraneous QSQSRVR jobs. This fix corrects how the internal    
structure is maintained. After the application of this PTF MySQL
or other QmyProcessRequest API client programs will need to be  
restarted.
