19.5. JDBC Object Store Support
19.5.1. JDBC Store for Transactions
Copiar enlaceEnlace copiado en el portapapeles!
Transactions can use a JDBC datasource as its object store. If the database to be used is configured for failover and recovery, this may be a better option than using disk space on an application server. The advantages must be weighed up against the fact that a raw JDBC object store is a special object store and may not perform as well as a file system or HornetQ journal object store.
Note
A JDBC datasource used as a Transactions object store must specify
jta="false" in the datasource section of the server's configuration file.
