All,
I'm trying to understand the free memory usage and why it falls below
17G sometimes and what could be causing it. Any pointers would be
appreciated.

All,
Not sure what's wrong in below execution plan but at times the query
runs for 5 minutes to complete and after a while it runs within a second
or two.
Here is explain analyze out of the query.
SELECT
OBJECTS.ID,OBJECTS.NAME,OBJECTS.TYPE,OBJECTS.STATUS,OBJECTS.ALTNAME,OBJE
with 10 disks (5+5).
Let me know if you need any other information.
Thanks Kevin.

That is odd; if your shared buffers are at 8G, you must have more than
4G of cache. How much RAM
Hi All,
I'm in the process of tuning a query that does a sort on a huge dataset.
With work_mem set to 2M, i see the sort operation spilling to disk
writing upto 430MB and then return the first 500 rows. Our query is of
the sort
select co1, col2... from table where col1 like 'aa%' order col1
the
output. I guess some sort of merge operation happens to get the first
500 records out.
Thanks,
Stalin

Hello All,
We have a postgres setup on solaris 10 with sun cluster for HA purposes.
2 nodes are configured in the cluster in active-passive mode with

however, when we either switch the resource group from one node to other
