Specifies the global JDBC connection SQL isolation level used
for container-managed transactions (by calling method setTransactionIsolation in
class java.sql.Connection). The precise interpretation
of this property, particularly Serializable,
is database-specific. Allowable values are:
ReadUncommitted
ReadCommitted
RepeatableRead
Serializable
If you are using container-managed persistence, Sybase recommends
you set the SQL isolation level to ReadCommitted and
configure the CMP logical isolation level for <persistentObject> and <queryMethod> commands
to best match the characteristics of the application. This allows
the persistence manager more options for database concurrency management,
and thus may help you to obtain better performance. For details
on the CMP logical isolation level, see ejb.isolationLevel.
