final class CloudscapeXAResourceHelper

extends XAResourceHelper

This class describes various methods to help the transaction manipulate XA resources from Oracle. This class has been tested with Oracle 8.1.6, 8.1.7, 9.0.1. For Oracle 8.1.6 the oracle classes (classes12.zip) must be in the Tyrex classpath because Oracle 8.1.6 requires the xid to be oracle.jdbc.xa.OracleXid. For Oracle 8.1.7 and above the oracle classes (classes12.zip) may optionally be in the Tyrex classpath.

boolean	treatDifferentBranchesForSharedResourcesAsShared() Return true if shared xa resources can be treated as shared even if they use different branches so that these xa resources are not prepared/committed separately even if they don't have the same xid.
boolean	useDifferentBranchesForSharedResources() Return true if shared xa resources must use different branches when enlisted in the transaction.The resource may still be treated as shared in that prepare/commit is only called once on a single xa resource (@see #treatDifferentBranchesForSharedResourcesAsShared}).
