IC91279: REDUCE INPUT PARAMETER BLOB SIZE OF THE DB2 MONITORING UDFS

Subscribe

You can track all active APARs for this component.

 

APAR status

  • Closed as program error.

Error description

  • Following UDFs have input parameter "XMLDOC BLOB(100M)":
    
        MON_FORMAT_XML_WAIT_TIMES_BY_ROW
        MON_FORMAT_XML_COMPONENT_TIMES_BY_ROW
        MON_FORMAT_XML_TIMES_BY_ROW
        MON_FORMAT_XML_METRICS_BY_ROW
    
    Calling these UDFs multiple times - especially within the same
    SQL statement  - can cause memory issues.
    Eventually this can lead to error SQL0930N - There is not enough
    storage available to process the statement..
    
    With this APAR we will reduce the BLOB size of the input
    parameter and therefore reduce the memory footprint when calling
    these UDFs.
