Yes, I'm trying to figure this one too... @gmananton if you find anything that helped resolve this, please post here. <3

[ecamaj]

oh, now I see this is an old issue... did you manage to solve this? Or anything that enabled you to run and connect to oracle db on Apple silicon?

I had a devil of a time with compiling binaries for Oracle 12c on RHEEL 8.6. Now TNS listener is working and Sqlplus launches but none of my accounts authenticate.

Same issue when recreate container with local volumed oradata ,but I oracle18 is ok

The root cause of the issue is that the if [ "$(ls -A /u01/app/oracle/oradata 2>/dev/null)" ]; then condition in the entrypoint.sh script determines whether the directory is empty. If the directory is not empty, it is interpreted as a restart scenario. Therefore, simply clearing the corresponding volume folder allows for a fresh installation.
