I have an Oracle 10G database running on two machines in a resilient environment with shared storage. So when one of our system fails we simply switch the GSS to second database instance. Now I need to upgarde my databases to Oracle 11G. Is there any way to do this without stoping the databases ?
Secondly let me know if data storage synchronization canbe done between a 10G and an 11G. If yes , then How to do it ?
