Does data guard work between 2 different patches of same oracle version?

Hi,

I've 2 11gR2 DBs with versions 11.2.0.2 and 11.2.0.3. I've a requirement to keep both these DBs in sync for HA. I am thinking of using Oracle Data Guard (DG) between these 2 DBs to keep them in sync.

I read that to setup DG, both primary and standby have to be off same Oracle Major Version. Hence, I thought DG can be implemented between 11.2.0.2 and 11.2.0.3 as the Major version remains 11gR2.

Please clarify.

Please note, both these DBs are hosted 2 different OS env. One is on Aix 5.3 and another one is on Suse Linux.

Regards,
Thasleem Basha
