Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Troubleshooting Guide


The hadbm process returns the following error:

HADB-S-05515: Shared memory segment with key "NNNNN" exists already

This can happen during HADB instance creation following a controlled stop without deleting a previously created instance that is using the same portbase. The problem may also be the result of a failed HADB instance deletion for any reason.
