Troubleshooting: Upgrade failed with a "Not enough shared memory available" error

Symptoms

The upgrade process ended abruptly when you were applying an upgrade, and the following error message was logged into the sm.log file:

E big_alloc: Not enough shared memory available to allocate <number> bytes

Resolution

Restore the database to the latest pre-upgrade state, increase the size of the shared memory (see Step 3: Perform preparatory tasks), and then restart the upgrade.
