ORA-01555: snapshot too old: rollback segment number 21
![]()
We upgraded multiple RTC instances at the weekend, our largest instance is now reporting issues, in the form of
ORA-01555: snapshot too old: rollback segment number 21 with name "_SYSSMU21_1855574189$" too small in the jazz.log. We were running at 3.0ifix1, and this is definitely new. From jazz/admin console we getting an error report on a background task, that is throwing the error. Background Task I seem to remember when the upgrade script was running, it suggesting that it would auto repair "stuff". Can anyone suggest what the problem is here, (I've done the google thing), and I am on to our DBAs to assist from an oracle perspective. Is there some additional steps we can take from an RTC perspective to find out exactly what is going on here? I shall raise a ticket on this to get a formal answer if nothing is forth coming from the foums. tvm dD |
