Hi,
You can get the instance's size from V$SGA or V$SGASTAT. Alternatively, use the "SHOW SGA" command:
SQL> conn / as sysdba
Connected.
SQL> show SGA
Total System Global Area 357091568 bytes
Fixed Size 731376 bytes
Variable Size 150994944 bytes
Database Buffers 204800000 bytes
Redo Buffers 565248 bytes
BTW: Before increasing PGA sizing, look at the PGA Advisor. Also, ensure you don't increase memory to the point where your system starts swapping.
Best regards.
Frank
