How to calculate PROCESSES parameter

Posted on 09-May-2008 By Admin No Comments on How to calculate PROCESSES parameter

SEMMSL

Set to 10 plus the largest initsid.ora PROCESSES parameter of an Oracle database on

the system. The PROCESSES parameter can be found in each initsid.ora file, loc

ORACLE_HOME/dbs directory. The default value of PROCESSES for the 8.1.5 prebuilt database

is 50.

SEMMNS

Set to the sum of the PROCESSES parameter for each Oracle database the largest one,

plus 2 times the largest PROCESSES value, plus 10 number of Oracle databases. For

example, consider a system that has three Oracle instances with the PROCESSES parameter

in their initsid.ora files set to the following values:

ORACLE_SID=A, PROCESSES=100

ORACLE_SID=B, PROCESSES=100

ORACLE_SID=C, PROCESSES=200

The value of SEMMNS is calculated as follows:

SEMMNS = ((A=100) + (B=100)) + ((C=200) * 2) +

((# of instances=3) * 10) = 630
