Dear All,
I've notice that my so called uncommited transaction is growing very fast.
The way I calculated this is by substacting the "Oldest Transaction" from
the "Oldest Active" form the gstat -h output. How to go about this?Any
pointer is much appreciated.
When the difference gets to hundreds of millions the db will be very slow in
processing requests. At this point I need to do a backup restore. Currently
I need to do this at least twice a month. I've just do a backup restore
yesterday and look at the difference between "Oldest Transaction" and
"Oldest Active"
