To manage or participate in transactions that span multiple WebLogic Server domains (that is, all participating domains run on WebLogic Server 9.x, 8.x, 7.x, or 6.x, or a combination of these versions), you must set the security mode for the communication channel and establish domain trust for all participating domains.
To enable inter-domain transactions, perform the following steps for each participating domain:
For more information about these options see Advanced Configuration Options
For information on how to configure Security Interoperability Mode for participating domains, see Setting Security Interoperability Mode.
If WebLogic Server 6.x domains participate in the distributed transactions, use the system password from the WebLogic Server 6.x domain.
For information on domain trust, see Enabling Trust Between WebLogic Server Domains.
After you finish
If you have domains running on WebLogic Server 6.1, see Changing the System Password for instructions to set the system password to the same value as the credential specified in domains running on later version of WebLogic Server.
