          Just apply the patch to Concurrent Manager Tier, you don't need to apply to another tier/web tier

                  Hi,

                   

                  Just apply the patch on one of the tiers and then run AutoConfig on both tiers.

                   

                  Regards,

                    Agree with Bashar, IF the Adpatch session actually ran AutoConfig. Otherwise you can obviously run AutoConfig, but it may not be necessary.

                     

                    Additionally; when AutoConfig is run, environment scripts may change. If they do - and you never know - you should re-source the environment, and start the environment with a newly sourced environment, after the respective AutoConfig ran on the node itself, be it in Adpatch or outside.

                     

                    Furthermore, you can/should/must/... (use as desired) recreate Appsutil.zip, copy to DB node, run AutoConfig there, re-source environment, and bounce the database. There you go, a complete Autoconfig cycle.
