Can you clone from the patch filesystem in EBS 12.2?

[Srini]

Hello,

Can someone please clarify the following questions?

1. Is it possible to clone from the patch filesystem instead of run filesystem?

2. Is it possible to run the R12.2 apps only 1 filesystem, that is have only run filesystem and have no patch filesystem at all?

3. Do we ever disable the logon trigger ever apart for any patching related activity on the patch file system so we can log in to the database and run the required steps?

Thanks in advance

1)No. If you try, you may find your way but it not recommended.. The patch filesystem stores applied patches to the run filesystem. It provides a clean baseline for future patching and upgrades. Cloning from there wouldn't include the base application code.
2)No. How will you patch it? How will you create a SR when you have issues? EBS 12.2 is a dual fs ERP, so if you go with single fs, it is not EBS 12.2 anymore. It wil become tainted. Furthermore, Oracle EBS 12.2 requires a separate patch filesystem for online patching.. Patching purposes, for patching processes.Using a single filesystem can lead to conflicts and issues during patching and upgrades.
3)there are cases where you temporarily disable it. To resolve the issues mostly -> for instance : ADOP Errors During Prepare (Doc ID 2107688.1) .. Trigger is there for online patching purposes. You can review its code and understand -> select dbms_metadata.get_ddl('TRIGGER','EBS_LOGON','SYSTEM') from dual;
