There is no problem with vaccum, i used to do it periodically...apart from vaccum i am asking things like table bloat, index bloat, duplicate index removal, unused index removal, cache hit ratio for table, cache hit ratio for index, .......what else?
Also, i saw cache hit ratio is only 2% for one big table and all other tables are around 9%. Is that a problem?

Of course amcheck tool is much better but it is an extension.wt., 17 paź 2023 o 19:59 Rajesh Kumar <rajeshkumar.dba09@gmail.com> napisał(a):I have been asked to check table health of specific big table.What are list of things I have to check?--
