-----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of JE Thinnes Sent: Wednesday, January 07, 2009 12:03 PM To: [email protected] Subject: MVS 4 minute 'outage' 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? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html This e-mail message and any attachments transmitted with it are confidential and are intended solely for the use of its authorized recipient(s).
