We just experienced a 4 minute 'outage' on our z/OS system. (single image z/OS 1.9 system). By 'outage', I mean we could not communicate with MVS through TSO or the z/OS consoles. There is a 4 minute gap in SYSLOG. The same for CICS, IMS and DB2 logs. There were no system dumps or other indicators. We reviewed SYSLOG for the 15 minutes that preceeded the 'outage' and did not find anything. TMONMVS had a 4 minute gap in the collector during the 'outage'. Any suggestions how we can determine what happened? <SNIP> I noticed no one has mentioned this. So, for the sake of argument, did someone hit the STOP "button" and then realized the mistake and hit "RUN" or some such (on the HMC or whatever)?
