Error running the container MEMORY_TARGET not supported on this system about docker-oracle12c HOT 8 CLOSED

How do you run the container? Did you use --shm-size parameter? Oracle AMM requires shared memory to be mounted.

from docker-oracle12c.

Hi @bofm

Thanks for the quick response, this is the command I've executed:

docker run -d --shm-size 1GB --name oracledb -p 1521:1521 bofm/oracle12c

from docker-oracle12c.

Is shared memory mounted on the host?
mount|grep shm

If it's not, try this:
mount -t tmpfs tmpfs /dev/shm -o rw,nosuid,nodev

from docker-oracle12c.

Yes, it is:

$ mount | grep shm
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)

Thanks for your help!

from docker-oracle12c.

Could you please
docker run --rm --shm-size 1GB bofm/oracle12c bash -c mount | grep -E 'shm|tmpfs'

from docker-oracle12c.

I had a very similar error and just had to increase the size of the shared memory.
Before:

• docker run -d --shm-size 1GB --name oracledb -p 1521:1521 bofm/oracle12c
  After:
• docker run -d --shm-size 4GB --name oracledb -p 1521:1521 bofm/oracle12c

Doing an attach to the running container showed exactly what the problem was:

• docker attach bofm/oracle 12c

from docker-oracle12c.

Exactly! Oracle attempts to use 40% of total memory and fails as there is only 1G available. If you are not planning to use more than 1G then just edit create_database script and set memory percentage according to your requirements.

If there is 8GB of memory on the Docker host and 1GB is planned to be given to Oracle database, then memory percentage should be set to 12 and --shm-size 1GB arg should be used when running the container.

Change memory percentage to 12 worked as charm, thanks for the help!
