Oracle Single 환경에 OCW Patch 를 적용해야 할까?
기본적으로 19.3 버전을 초기 설치하게 되면 non RAC / non ASM 환경임에도
29585399;OCW RELEASE UPDATE 19.3.0.0.0 (29585399) 해당 패치가 같이 설치가 된다.
이후 Patch 관리를 해줘야 할 떄, Database RU 외에 OCW (Grid)도 같이 해 줘야 하나? 하는 의문이 생긴다.
-> 결론부터 말하면 선택사항이며 오라클에서는 보안패치가 포함되어 있기 때문에 같이 해줄것을 권장하고 있다.
-> 같이 관리해 주고 싶다면 GI RU 를 받아서 OCW와 DB RU를 개별적으로 Patch 적용해 주면 된다.
==========================================================================
APPLIES TO:
Oracle Database - Enterprise Edition - Version 19.3.0.0.0 and later
Information in this document applies to any platform.
GOAL
Is it or not necessary to apply OCW patches on my ORACLE_HOME even if I don't use ASM, RAC or CLUSTERWARE?
It is optional, but even if no GI Stack (ASM, Clusterware or RAC) is used inside the server, it is recommended not to ignore the security patches of the installed components. And apply the most recent OCW Patch.
From version 19c onwards, the Patch 29585399 OCW RU is included from the initial installation.
[oracle@localhost ~]$ opatch lspatches
29585399;OCW RELEASE UPDATE 19.3.0.0.0 (29585399)
29517242;Database Release Update : 19.3.0.0.190416 (29517242)
OPatch succeeded.
SOLUTION
To apply the latest OCW patch, it is necessary to do it manually. This must be done by downloading the latest GI RU patch, unzipping it and placing it in the directory corresponding to the OCW and apply it using "opatch apply".

Patch 35319490: GI RELEASE UPDATE 19.20.0.0.0.0 will be used.
