On OpenVMS Alpha and I64 systems, the XA Gateway Control Program utility (XGCP) provides the management interface to the DECdtm XA Gateway and creates the transaction logs used by the DECdtm XA Gateway. It can also be used to stop and restart the XA Gateway server. The Gateway allows a DECdtm-compliant resource manager, such as RMS Journaling or Oracle Rdb, to be used with an XA-compliant transaction manager.
