From CA Support, we recommend doing the following.
1. On the machine with the Oracle database, set up a Oracle Listener (llistener.ora) for the database.
2. On the machine containing the Transaction Enabler (TE) and server load modules, set up a Oracle SQLNET alias in the tnsnames.ora.
3. On the TE machine, use SQLPLUS to verify you can connect to the remote database using the SQLNET alias.
4. Edit the aeenv file to have the following format: TRAN <trancode> <loadmodule> <userid>/<pswd>@<tns_alias>
If this does not work for you, please open a case with CA Support.
