Review this topic to understand the requirements and procedures for installing the 12.1.2.6 patch set release for Oracle Database Appliance.
You must complete all required tasks before starting to install the Oracle Database Appliance 12.1.2.6 patch. Your Oracle Database Appliance infrastructure and grid components must be upgraded to the Oracle Database Appliance 12.1.2.5 patch set before you can upgrade to Oracle Database Appliance patch set 12.1.2.6. By default, patch updates include patch updates to the Oracle Database software. However, you can continue to run earlier release Oracle Database homes, and update Oracle Database at a later time.
Read the patch readme file for release 12.1.2.6, and read the help files provided for the 12.1.2.6 patch installation.
Overview of the 12.1.2.6 Patch Upgrade

About Applying the Oracle Database Appliance 12.1.2.6 Patch Set Bundle
When you apply the Oracle Database Appliance patch set bundle, you must apply the patch set components in the following order:
infra: Infrastructure
gi: Oracle Grid Infrastructure
database: Oracle Database
For the Oracle Database Appliance 12.1.2.6 patch set update, you run the patch set updates using the --local option, which runs the patch update on the local node only. The other node is not affected. When you run the infra patch on Node0, the --infra --local options restart Node0. You must wait until the restart is completed on Node0 before proceeding to the GI patch. Also, when you run the GI patch using --gi --local, the Oracle Grid Infrastructure patch is run only on the local node. While you upgrade Oracle Grid Infrastructure on Node0, Node1 remains available.
Complete applying the infra and gi patching on Node 0 before you start to patch Node 1.
Oracle Appliance Manager verifies that a patch meets all prerequisites to prevent you from installing patches in the wrong order. For example, you cannot patch Oracle Grid Infrastructure before you update the server infrastructure.
Caution:
The --local option runs patch update commands only on the local node where the command is run. The other node is unaffected by patch commands run with the –local option. You must complete all of the steps of this patch procedure for both nodes to maintain the integrity of the Oracle Database Appliance system.
