impact when TIMED_STATISTICS = TRUE
I am trying to troubleshoot a strange problem that one of two databases on a physical server sometimes does not allow any connections anymore, not even CONNECT / AS SYSDBA from the console. To see if there are any issues with the troubled database, I installed Statspack to monitor the DB. However, since the connection problem can not be reproduced in a predictable manner, I intend to do statspack every 1/2 hour until it refuses connections again. This may not happen in a month or longer.
My question is: are there any issues (performance, spaces, etc) I should watch out if I set TIMED_STATISTICS=TRUE for a long period of time? I searched through Oracle docs but did not find concrete answers on the impact of TIMED_STATISTICS.
