Hello !
We have Oracle 9.2.0.6 on Sles 9 (SP3) x86 with 2.6.5-7.244-bigsmp and 5G of RAM !
We want to increase the sga from 1G to 1.5 G. Of course when we want to start the database we hit
  "ORA-27123: unable to attach to shared memory segment"

Now, I've been reading a few documents (most of them for RedHat !) about how it can be done and it seems that mainly there are 2 ways to do that : hugetlb and bigpages ! Which is the best way for sles 9 and how it can be done with the minimum loss of performance ?
