About Oracle Exadata Infrastructure Patching
Oracle Fleet Patching and Provisioning (Oracle FPP) supports rolling patching of Oracle Exadata infrastructure, including storage cells, network switches, and database nodes.
Patching Oracle Exadata infrastructure involves choosing a driving node from which you start the patching operation. A driving node can be either the Oracle FPP Server, or any of the Oracle FPP Client nodes.
Use the
-server
option to initiate the patching
operation from the Oracle FPP Server. For this patch driving mode, the workflow is
as follows:
- Establish passwordless SSH
root
user equivalence from Oracle FPP Server to the target node. - Evaluate the patch operation impact (
-eval
precheck). - Apply the patch using the
rhpctl update exadata
command.
Use the
-client client_node_name
option to initiate the patching operation from the Oracle FPP Client. For this
patch driving mode, the workflow is as follows:
- Establish passwordless SSH
root
user equivalence from Oracle FPP Client to the target node. - Deploy the image on the target node using the
rhpctl import image
command. - Evaluate the patch operation impact (
-eval
precheck). - Apply the patch using the
rhpctl update exadata
command.
If the patch operation fails for any reason, then Oracle FPP enables you to rollback the cell server and database node patches, and downgrade the network switch patches.
