  • Closed as program error.

Error description

  • Parameter query_heap_sz is deprecated in Version 9.5 and might
    be removed in a future release. This parameter can still be used
    in pre-Version 9.5 data servers and clients. In Version 9.5 and
    later releases, the value specified for this configuration
    parameter is ignored.
    
    However, trying to increase parameter aslheapsz in a Db2 10.5
    you get:
    
    db2 update dbm cfg using aslheapsz 8192
    SQL5153N The update cannot be completed because the following
    relationship
    would be violated: "query_heap_sz >= aslheapsz".
    
    There is still an existing check rule left over.
    

Local fix

  • First update the size of query_heap_sz in order to fulfill this
    rule.
