Error description
Impact - incorrect reporting of Internal Response date. We have a modified version of DFH$MOLS that displays the Internal Response (IRESP). IRESP appeared ok, except for some transactions. The transactions for which it appeared wrong had a significant 'think time' - TC I/O Wait. Looking at the origin of Internal Response time, I found a bug in the source. DFH$MOLS calculates the wrong Internal RESP value for all release of CICS/TS where there is a non-zero TC I/O Wait value. It is obvious when one uses CEMT I TAS interactively, leaves the CEMT display for 2 minutes, then exits CEMT. Post-processing the SMF 110 performance records for this CEMT tasks shows that PDRIRESP is just short of 2 minutes, whereas it should be subsecond. Additional Symptom(s) Search Keyword(s): KIXREVCTC

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: DFH$MOLS PDRIRESP field is reporting * * the incorrect value. * **************************************************************** * RECOMMENDATION: . * **************************************************************** The provided DFH$MOLS sample is using the first four bytes of the timestamp value in PDRTCWT when calculating the PDRIRESP value rather than just the time portion. This results in PDRIRESP being reported as a larger value than intended.
Problem conclusion
DFH$MOLS has been altered to correctly calculate the PDRIRESP value.
