RE: Server sizing for Oracle Application + Database

Irfan,

   For the memory sizes, you can look into the Oracle Forms sizing 
recomendations, this would cover the online users. Also you need a large amount 
of memory for the java components, each JVM uses at least 512Mb. There are four 
of them, and they are enabled even if you are not using them.  There is a note 
specific to self-service JVM tuning on metaling that brings some references to 
the memory sizes.

      For the database the Oracle Applications database initialization 
parameters note has some recommended memory settings. The concurrent will be 
guesswork, you should use at least the same amount of memory you are allocating 
for the database. The concurrent manager memory is dependent on the amount of 
managers you intend to run.

       For the CPU and disk sizes you are on your on, since this is dependent 
on the workload. You can look into some Oracle Applications benchmarks to try 
to extrapolate the values. And you need to be aware of the load profile. A 
system that receives lots of information from legacy applications to process 
them in batch would use a lot of disk and CPU power even if there are few 
users. A system that has most data inputed by online users would be much less 
demanding on the hardware.

       Oracle has a sizing spreadsheet, but it is internal, you would need to 
ask Oracle Consulting to do the sizing for you. The sizings I have seen from 
Oracle were usually underestimated.

Regards,
Luis

Please read the document/manual for the O/S you are planning to install. That 
has the minimum requirements - which I think is good for installing on  our 
home pc/server. I have never seen oracle minimum requirement at a client site.
There will be no chart/template thats fits for all environment. 
You can request sizing (h/w, memory & cpu) from your hardware vendor - normally 
they do it for free.

Good luck

Hello,
 
I am looking out for a template or chart which will help me decide initial 
processing speed, RAM size and storage space of server taking Oracle database 
and Application into consideration.
