Hi

What are the measurement I have to take If I am going to increase the number of Processes from 150 to 200. Do I need to change any other parameter value or simply I need to run the query (alter system set processes=200 scope=spfile;)

System is already running with ASMM (Automatic Shared Memory Management) enabled.

Also please let me know if I have to change anything in Listener.ora.

Thanks

system parameters, but we don't know what Operating System (name & version) or Oracle version (to 4 decimal places).

When all else fails Read The Fine Manual

http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams.htm#i1132608

I realize that it is easier for you to have me lookup the answers for you, rather than you doing so yourself.

Enjoy!

>Oracle : version 10g
Not exactly 4 decimal places as previously requested.
Could you benefit from remedial counting training?

I have already read this document.. but I wanted to know from a real time environment..

I will simplfy my question.

Can I directly go ahead and increase Oracle processes from 150 to 180?
(using the command Alter system set processes=180 scope =spfile;)

No, because PROCESSES can not be changed dynamically.
It can be changed only when DB is down.

I stand corrected.
Long story short is/was I misread response.
scope=spfile succeeds
scope=both fails - which is what I thought I saw.
