We're facing an Out Memory Problem with an Oracle database SE 12c Release 1 (deployed as a Docker container) …
The only information that I have is this one:
Caused by: java.sql.SQLRecoverableException: ORA-01034: ORACLE not available
ORA-27102: out of memory
Linux-x86_64 Error: 12: Cannot allocate memory Additional information: 2673
Additional information: 360449 Additional information: 1627389952
I try to google the ORA-27102
but the forum discussions are to broad (to implement any solution will be like shotting in the dark) … I don't know how to narrow my problem? Does anyone know what those additional information
codes are (I tried to google them without success) ??
Any suggestion will be appreciated!

I'm presuming you don't have metalink as this was the first hit:
SYMPTOMS
Instance not reachable and process dying.
Background processes are dying and oracle is unable to spawn new processes. Clients cannot connect and they receive error:
When this happens local connections are not possible, but already existing connections continue to work. The problem appears when running backups or complex queries then it disappears.
No specific memory related error is reported on the server log just logs like this one:
CAUSE
