Dear Big Iron People, (Still waiting to get on the CICS-L list)
FFST/MVS (First Failure Support Technology/MVS): http://pic.dhe.ibm.com/infocenter/zos/v2r1/index.jsp?topic=%2Fcom.ibm.zos.v2r1.e0za100%2Fe0za10015.htm Q1). How do we know if we are taking advantage of FFST/MVS? Where can I look, or what can I enter to know if we have FFST enabled? CICS says a program might call the first failure symptoms component. It's documented in the CICS TS for z/OS 5.1 Installation Guide in Chapter 30. MVS ASREXIT - SYMREC Authorization Exit. I read the CICS Problem Determination Guide. There are quite a few references to first failure: General CICS tracing is handled by the CICS trace domain. It traces the flow of execution through CICS code, and through your applications as well. You can see what functions are being performed, which parameters are being passed, and the values of important data fields at the time trace calls are made. This type of tracing is also useful in first failure data capture, if an exception condition is detected by CICS. In addition, exception trace entries are always written to the internal trace table, even if no trace destinations are currently started. Other trace destinations that are currently started get the exception trace entry as well, but the entry always goes to the internal trace table even if you have turned tracing off completely. This function provides first failure data capture. CICS exception tracing is always done by CICS when it detects an exception condition. The sorts of exception that might be detected include bad parameters on a domain call, and any abnormal response from a called routine. The aim is "first failure data capture", to record data that might be relevant to the exception as soon as possible after it has been detected. It may just look like they could be related. I didn't find a section in the CICS manuals (yet) about a CICS "first failure symptoms component". Q2). Does anyone know if CICS "first failure" has interactions with FFST/MVS? Also would you know where I can find more information on this CICS "first failure symptoms" component?
