ORA-29516: Aurora assertion failure: Assertion failure at joez.c:3311

Symptoms
This type of error may appear in the alert log upon instance start-up on Linux:

Wed Jun 23 16:44:13 2010
Errors in file /app/ORCL/product/orcldb/11.2.0/admin/ORCL/diag/rdbms/orcl/ORCL/trace/ORCL_m000_20219.trc:
ORA-29516: Aurora assertion failure: Assertion failure at joez.c:3311
Bulk load of method java/lang/Object. failed; insufficient shm-object space

It may also occur when attempting to reference a Java class method or a function within the DBMS_JAVA package, such as LONGNAME.

Changes
You have set JAVA_JIT_ENABLED=TRUE (or not set it all, in which case it defaults to TRUE).

Cause
You have set additional mount options on the shared memory device, /dev/shm, other than just the option named defaults.

Solution
If you see any other mount options in file /etc/fstab after the word "defaults" for /dev/shm,
such as nosuid, nodev, or noexec:

none /dev/shm tmpfs defaults,nosuid,nodev,noexec 0 0

then remove these options from the entry in /etc/fstab:

none /dev/shm tmpfs defaults 0 0

shut down the database instance, and reboot the system.  Restart the database instance.  The errors should no longer appear.
