Hi,

Thanks for the extensive discussion.

In my case,vacuum performance plays an important role. Hence, I shall run only 
one server at a time while profiling.

Thanks a ton,

Atri

You're perfectly right. I'm used to have several clusters on the same
host (application testing in my case).
In this benchmark context, though, I just was being wary that they may
interfere, For instance, I suppose that an autovacuum wakeup in one
should lower performance results of the other.

Sorry it that sounded more general than that.

why? its perfectly OK to ahve severla postgres servers running at once, 
as long as they are on different port numbers.   I generally use 5432, 
5433, 5434, etc for this.   mostly for development, or for migration, 
not so much on a production system where performance is important.

Thanks a ton, I get it now.

Hi,

I'm by no means an expert in pgbench, but this is client software
relying on libpq.
You can make it work against the secondary server simply by specifying
its port with -p option or PGPORT environment variable.

If that matters, to make sure that the right version of libpq is being
used, you can use LD_LIBRARY_PATH, something like

export LD_LIBRARY_PATH = /usr/local/pgsql/lib

ann use if possible the pgbench from the secondary install.

Make sure both servers aren't running at the same time :-)

Regards,

[GENERAL] pgbench help

2012-12-23 Thread Atri Sharma
Hi all,

I have two 9.2 servers running in different data directories and
installation directories. One of them(the main one) has its bin in the
path of my system.The other one does not, hence, I need to use the
complete path(/usr/local/pgsql/...).

I want to run pgbench on the second server. How should I configure
pgbench to use the second server's psql?

Thanks,

Atri
