We are on a Oracle Enterprise edition with a data guard setup. It is in a large enterprise where all databases and servers and administered by dedicated teams.
Our primary and secondary databases run on separate servers. The data guard broker is located on a third server.
When doing patching, the database servers are taken down causing downtime for the business, which is critical 24/7 and sensitive to downtime.
My questions:
Is possible to patch/restart the secondary database and server, while still running the primary online?
Can the data guard broker server be patched without downtime for the databases?
Thanks in advance and please let me know if you need more information.
