JBoss with Hypersonic messaging queue Database in production environment.
Since hypersonic database is a flat file database and can not handle a large load of transactions, it is not recommended to use Identity Manager on JBoss (any version) with hypersonic database for production.
It is CA and JBoss recommendation to use a relational database as the messaging queue database, such as:
Microsoft SQL server.
Oracle MySQL
