Oracle to Postgres Migration - Duplicate Key Issue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi all,

 

I’m in the process of migrating a web application from Oracle to PostgreSQL.  After a few headaches, I’m almost there but one pesky issue is blocking me.  When the application first deploys to JBoss, it builds its environment in the Postgres db via hibernate.  I am getting intermittent duplicate key errors (see example trace below) for auto-generated hibernate keys during this process.  About half the time, the environment loads without issue and, when there is an error, it is always at a different point in the process.  Can anyone think of any differences between the two dbs (Postgres and Oracle) that could lead to this behavior?  Thanks.

 

Additional information;

 

Wildfly 8.2

Spring 4.1

PostgreSQL 9.4

Hibernate 3.64
