Zero Down Time Patching: Database Rolling Process

1. Patch the Oracle Home Out of Place

2. Drain the workload• Shutdown Data Sources• Relocate Services• Transactional Disconnect

3. Shutdown the Instance gracefully

4. Switch to the Out Of Place Oracle Home

5. Startup the Instance

6. Allow the load to rebalance

7. Repeat Drain, Shutdown and Switch on the remaining instances

8. Apply the SQL

Zero Down Time Patching: Middleware Rolling Process

1. Patch the Oracle Home Out of Place

2. Quiesce the first Managed Server and shutdown• In 11g: Graceful shutdown or suspend and then force shutdown

through WLST• In 12c: Graceful session shutdown

3. Oracle Home is switched with Patched Home• For shared storage, this could be a un-mount/mount• For local, this could be expanding a patched archive or could

involve patching in-place

4. First Managed Server is started

5. System load is redistributed

6. Proceed with the next server until the entire system is patched

• Setup multiple managed servers

• Turn on session replication

• Perform “Graceful Session Shutdown” when states are not compatible

Zero Down Time Patching: At Scale Process

• Modularize the functionality required to patch a single “VM”• Automate the patching of a single “VM”• Provide a GUI based control and monitoring app• Define a connection infrastructure• Allow each “VM” to patch independently • Add a notification and alert system for failures• Provide a playbook for operators when errors occur
