Hi, just some questions, no solution so far: ? are you running RAC or is it a single node? ? have you checked for any traces (especially PMON) during this periode? ? was there heavy load on the node durint this periode? far away from answers, but just a start. br, Martin Am 29.01.2009 um 17:07 schrieb Guillermo Alan Bort:
This is a 10g database (10.2) monitored through Grid Control. Every once in a while we get a TNS timeout on the EM side, and at the same time we get something like this in the listener log: 02-JAN-2009 21:04:45 * service_update * fcrsgx * 0 02-JAN-2009 21:08:30 * service_update * fcrsgx * 0 02-JAN-2009 21:08:30 * service_died * fcrsgx * 12547 TNS-12547: TNS:lost contact 02-JAN-2009 21:08:42 * service_register * fcrsgx * 0 02-JAN-2009 21:08:54 * service_update * fcrsgx * 0 Now, this outage is noted by CT. We are opening an SR with Oracle Support, but they work VERY slow, so perhaps someone here has an insight into this problem.
