Monitoring the tasks DCDCONTL and DCMMAIN, the DCDCONTL is performing large number of I/Os (EXCPs). What is causing this?
The excessive EXCPs I/O's appear to be generated by events that aren't actually EXCP requests. A PMR was opened with IBM to explain the behavior. In the interim, DCD maintenance was developed to greatly reduce these EXCP I/O 's.
Release : 3.0
Component : CA DATA CONTENT DISCOVERY
Adding the statement IJO="$IJO -Ddb2.jcc.tracePolling=false" to CFEYOPTN(FEYCTRLR).resolved the excessive I/O's.
