when upgrade 188.8.131.52 to 184.108.40.206 on my virtual machine, encountered the ora-00845 error. Run the checking utlu111i.sql, the memory_target for the database is more than 436M, my virtual machine just has 319 shared memory. Follwoing is the interpret of Metalink:
This feature requires the /dev/shm file system to be mounted for at least %llu bytes.
/dev/shm is either not mounted or is mounted with available space less than this size.
So the solution is tuneup the size of /dev/shm in /etc/fstab:
tmpfs /dev/shm tmpfs defaults,size=1024m 0 0
then restart the box or re-mount the mountpoint.
