Cutover Phase Requires a brief downtime.
Following activities occur during Cutover:
+Users are logged off the system
+Finalize is run as part of cutover -if not run earlier in adop cycle
+Cutover phase cancels ADZPPATCH Concurrent Program
+Stops all Services on RUN and PATCH editions , switches filesystem and starts services on new RUN FS
+Flipping snapshots in run and patch editions.
+Users are brought back online on the patched system
Environment is changed after cutover. Need to Re-source the env, for performing any actions after cutover.
Syntax:
$ adop phase=cutover
Multi-node Considerations
========================
By default cutover is invoked automatically on remote nodes.
If you want cutover individually:
1. First node the cutover should be:
$ adop phase=cutover allnodes=no
2. For all other nodes you should do:
$ adop phase=cutover allnodes=no action=nodb
* nodb because db work is already done
Cutover Parameters:
===================
mtrestart :Specifies whether or not to start Mid-Tier services at end of cutover, it allows you to perform some additional maintenance operations in the system before bringing it up. – Takes values “yes” or “no”. – Default: yes
allnodes : Specifies whether or not to run on all the nodes. – Takes values “yes” or “no”. – Default: yes
action: Specifies whether or not to take database action – Takes values “db” or “nodb” – Default: db
