Issue/Introduction

When viewing the Exception Detail screen, the INDB2_TIME is less than the  ORIO_WTIME & INDB2_CPU TIME. Also, the Fetch Count is zero when 10 rows were fetched. Is this correct?

Resolution

Both the INDB2_CPU & the ORIO_WTIME can be larger than the INDB2_TIME. For SQL requests that use CPU parallelism the INDB2_CPU & ORIO_WTIME are accumulated across all of the parallel tasks. Also, the INDB2_CPU includes both standard CPU and zIIP CPU time.
