Can't set the shm_size for oracle xe

[AlfAtGitHub]

My oracle xe container is currently not starting because of a lack of shared memory:
"A database XE container needs at least 1 GB of shared memory (/dev/shm)."

My problem here: How can I set the shm_size (shmSize) for OracleContainer respectively GenericContainer?

I've already tried: .withCreateContainerCmdModifier(cmd -> cmd.withMemory((long) 4 * 1024 * 1024)).

Also tried some settings within the testcontainers.properties. Unfortunately I've not found what params are available and how to set it here.

Any help welcome. Thanks.

I am also hitting the exception

Here are the logs from Docker docker logs $ORACLE_CONTAINER -f

/dev/shm (--shm-size) needs to be at least 1G
The Oracle base has been set to /u01/app/oracle
/dev/shm (--shm-size) needs to be at least 1G

The change in #957 makes sense of course.
But is this a change that has been introduced in a more recent Oracle XE image?

It's working for me with image wnameless/oracle-xe-11g@sha256:825ba7 by the way.

I am not using the wnameless docker image -- i've built my own docker image according to the Oracle GitHub documentation which I've linked in the pull-request;

https://github.com/oracle/docker-images/blob/master/OracleDatabase/SingleInstance/FAQ.md

Looking at his source; he's commented out

#memory_target=1073741824
(https://github.com/wnameless/docker-oracle-xe-11g/search?q=memory&unscoped_q=memory)

Given that you should be able to provide your own image; I think this is a worthwhile change still.

Yeah, I think it makes sense to do this for the OracleContainer class.
I’m just wondering if the solution should be to keep Testcontainers API as-is, and have the OracleContainer class use the docker-java API specifically to request shared memory...

Someone might want to run their own Oracle container not through the provided testcontainer Oracle class -- I think exposing the API through GenericContainer is the correct approach. It's set the ground work for any other HostConfig variables too.
