Oracle Database Discussions

Hello everyone,

I have to upgrade my db since all the problems that i have with memory´s dump, my question is, to upgrade the db from 10.2.0.1 to 10.2.0.4 ¿i need to download all the patchsets like 10.2.0.1 > 10.2.0.2 > 10.2.0.3 and 10.2.0.4 or i can upgrade only with the update 10.2.0.4, like 10.2.0.1 to 10.2.0.4?

My system has dataguard, ¿there is any problem to update or settings that I have to touch after the upgrade?

In the upgrade ¿ What instance has to be update first the primary or the secondary database ?

How I can upgrade the secondary database if he is in read only (standby db of dataguard).

Thanks for all the support.
