Example of setting default resource control project for a user, e.g. oracle. It will guarantee the effectiveness of the settings.

projadd -U oracle \
-K 'project.max-sem-ids=(priv,9216,deny)' \
-K 'process.max-sem-nsems=(priv,9216,deny)' \
-K 'project.max-shm-ids=(priv,4096,deny)' \
-K 'project.max-shm-memory=(privileged,60G,deny)' \

In above, it sets 60G as the max shared mem for user oracle.

To set default project for other user, you can replace oracle with username, and adjust the parameters accordingly.

To verify the settings:
oracle$ id -p
uid=100(oracle) gid=100(dba) projid=100(user.oracle)
