We have a AIX box running Sybase..Unfortunaly we have no sybase unix person or dba..I know about dba on Sun and Oracle..

My question(s):

1. We need to look at the tuning parameters for sybase. How do I get that info?
2. What are some simple parameters to check and change that will give the best performance?
3. Is there a gui tool on the aix for sybase that help view the sybase database.

1) The Sybase ASE documentation is online at http://manuals.sybase.com/onlinebooks/group-as/asg1250e
In particular, you will want to read the System Admin Guide for sp_configure parameters, and the Performance and Tuning Guide.

2) Well, "total memory" should be as high as possible on your box.  "Max online engines" should probably be set equal to the number of CPUs  (I'm assuming, of course, that this box is dedicated to a single ASE server)
But this is very rough advice.

3) Depends on your version, but there is a Sybase/SQL Central GUI.  The older version was PC-based, the newer version is Java based.  I can't tell you much about it, I never use it.

McCrawFish,

What is the purpose of your AIX server?  Is it a database server?  Is it a database/webserver?  Do you have Java beans/middle tier exe on it?  How many "engines"(CPUs) are on the server?  How much memory do you have?  How many disk controller(s)/disk(s)?  Are they simple disk arrays or are they EMC disks?  What type of database (data warehouse or OLTP)?  Is it web based, wan, lan, etc?
What size is your current database?  Expected growth(per month/year)?
