While testing October 2019 quarterly patch wrapper for Oracle 19c Grid setup on Linux environment, it was observed that one of the cluster related command "crsctl" output is slightly different than that for earlier versions of Oracle databases. Due to this change, one of the BDA's activity during grid patching "AutoStart Services" was failing. To address this command output change, we had to modify the BDA code. This modified BDA code is available through the HOTFIX.
So, if you are trying to patch your Oracle 19c Grid Setup with October 2019 GIPSU patch, make sure you apply the HOTFIX in advance i.e. before you start patching.
Kindly get in touch with our support team to get this HOTFIX.
