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
