Authentication to Oracle Applications Systems
TIBCO accesses the Oracle Applications distribution target through the user name (ESISYS) and a password specified in each adapter instance deployment configuration. This user name is configured in the distribution target at implementation time. In other words, Windchill ESI does not support dynamic logon to the ERP distribution target. The ERP distribution target logon information for the adapter is also specified at the time of implementation.
