What are the Commonly Used SGA Sizes on VLDBs ? Answers below:

On SUN E6500 (4u) model , Solaris 2.6 , we are Unable to increase the SGA Beyond 1.7 GB on Oracle 7.3.4.5

-->Max size on 32 bit OS and oracle, 2.6 is 32 bit

Qs. What are the ways of increasing the SGA beyond this Limit ?
--> Upgrade your OS and Oracle to 8i

Qs. What are the Negative Implications of of RE-Creating the Oracle Exe With a Lowered Base Address to Allow Bigger SGA ?
--> Good luck on this one

NOTE - This may Give us a Only a Few Hundred MB . What if we Need MORE ?

Qs. Would this Limitaition be on Oracle 8i too ? It is a limitation on 32bit vs 64bit oracle and os
