I do not understand. Please give more details. I know a few things about oracle, but I do not claim to be an expert as you can see. Should I just type in command prompt LOCAL=<the name of the instance>? Like LOCAL=test? I have tried. Nothing. Could you please give me some more details Please?! Thank you!

When you increased memory exceed the total of physical memory, you usually encounter like this error message. The SGA includes Shared Pool, DB buffer Cache, Redo Log Buffer, Java Pool and Large Pool.
Sometime I attempted to increase SGA.
When you get this error message, don't sad or worry. From the Oracle 9i, the Instance startup by spfile - server parameter file which created by pfile manually. However, when you re-create spfile from the exists pfile, some parameters that was tuned will become for the firs time.
..shared memory realm already exists
....
SQL> Shutdown abort
Instance shutdown
Create spfile from pfile
With Unix..
$SQL>create spfile from pfile='/u01/ORACLE_HOME/DB_1/DBS/initSID.ora'
File created
$SQL>startup mount
....
Instance startup
SQL>Alter database Open;
With Windows..
SQL>create spfile from pfile='C:\ORACLE_HOME\DB_1\DBS\initSID.ora'
File created
SQL>Startup mount
...
Instance start
SQL> Alter database open;
Database opened
If necessary, backup the pfile to the other location.
The oradim -SID is need to create one new SID, sometime it's unnecessary.
Regards!
