Hi,

A question on database instance creation? Now I have two applications and each has over 30GB data. For this kind of situation, which choice below is better interms of execution performance and management:

1) create two database instances (i.e., SID orcl1 and orcl2). Then each application occupies one database instances.

2) just one database instance. And each application has its own tables created inside.

Thank you very much.
Simon

hi,

if you are having the two application in same database,
then
then size of database 60gb.

then the sga of the database should be 1 to 2 percent of the whole datbase.if it is 2 percentage,sga size should be 1200mb(1.2gb).if it is one,then 600mb.
if the sga size is more than your physical memory,then swapping will be done which will reduce the performance.

if you are having two database,
for each database,
if the database size is 30gb then the sga of the database should be 1 to 2 percent of the whole datbase.if it is 2 percentage,sga size should be 600mb
if is one,then sga size is 300mb.

god only save you.

just joke.

now i am moving.please contact me through my email
