Re: [castor-dev] [JDO] Key generator -- Duplicated Identity is generated!

[Stephen Ince]

Emir,     We have a load testing product that uses castor as the database abstraction layer and once in a blue a user will come back with this error. This is the last email I received about the error. Once we a tell the user to start and stop the application it goes away, so I know that the key generator cache is out of sync with the max value in the database.     Nested error: org.exolab.castor.jdo.PersistenceException: Nested error: Key Generator Failure.

Hi Stephen, Could you please send some more info on this? Do you have a stack trace or some common scenario when the duplicate identity exception is occurring? I’m not a Castor developer, but just interested in the matter.   Regards, Emir       -----Original Message----- From: Stephen Ince [mailto:[EMAIL PROTECTED] Sent: 24. travanj 2004 2:32 To: [EMAIL PROTECTED] Subject: [castor-dev] Key generator -- Duplicated Identity is generated!   I am using the castors key generator to generate key ids. I am intermittently getting duplicate key ids. Does anyone know of a method to have castor refresh the key generator cache if it becomes out of sync with the database? I use a plethora of databases, oracle, db2, sql server, and hsqldb.     org.exolab.castor.jdo.PersistenceException: Nested error: Key Generator Failure. Duplicated Identity is generated!'
