Re: Standby databases and different sids

Well, Oracle docs say:

"Primary and standby databases must have the same version, release and patch for:
- Oracle RDBMS and
- Operating System".

So upgrade your Standby to Solaris 8. AFAIK it is not required, that stanby db has the same sid, as primary, although it is recommended.
