Question about access to db server

От

Hello,

We are running PostgresPlus 8.4AS on a linux system. I don't need to edit the config files or to restart the clusters (the DBA will do that for us). I only need access to help troubleshoot performance issues with the databases.
My question is: would pgAdmin be sufficient for what i need to do? From what I understand, i can check the status of the database, view the postgresql logs, the postgresql.conf and pg_hba.conf.
 
I appreciate your input for my question.

TIA.

The DBA should do that job.

 I didn't know what PostgresPlus was so I looked it up. Firstly it has
tools for tuning PostgreSQL and secondly, it is a tools package for
the Enterprise version of PostgreSQL, so presumably you can get the
support that you presumably paid for.

Cheers,

Cliff

Good Evening,

Before tuning the hardware settings I usually execute an EXPLAIN to see the execution path Postgres uses.  A good start to understanding the EXPLAIN functionality is here http://wiki.postgresql.org/wiki/Using_EXPLAIN .  Since you're using pgAdmin this is a better tutorial http://www.postgresonline.com/journal/index.php?/archives/27-Reading-PgAdmin-Graphical-Explain-Plans.html .  Sometimes using an join instead of a subselect or indexing greatly improves a query even before trying to optimize the default postgres settings.

Thanks
-Mark
