If extOracleOutAtlanta or extOracleOutBerlin refuses to accept eWays, this issue may be an indication that the referenced eXchange database instance is:
Inaccessible, in which case ensure that Oracle is running and that the Environment’s extOracleOutAtlanta or extOracleOutBerlin properties match the instance’s host name, SID, user name, and password. If necessary, see the Creating Atlanta Company’s Environment or the eXchange Integrator User’s Guide for more information.
Misdefined as inbound, in which case delete the Environment’s extOracleOutAtlanta or extOracleOutBerlin and re-create either instance as outbound. Then, click Save All, followed by Refresh All from Repository.
