Creation of fieldid_fieldconfig index fails in DB2

The problem is that "fieldid_fieldconfig" index name is too long. To correct the problem edit WEB-INF/classes/entitydefs/entitymodel.xml file and rename "fieldid_fieldconfig" to "fieldid_fieldconf". Then drop and recreate the database and restart JIRA.

If you do not wish to drop and recreate the database just edit the WEB-INF/classes/entitydefs/entitymodel.xm file and then run the following SQL in your database:

CREATE INDEX fieldid_fieldconf ON DB2INST1.optionconfiguration (FIELDID, FIELDCONFIG)

Please use the correct schema name in the SQL above. "DB2INST1" is the example schema.
