Task 5: Configure Net8 (Multiple Instance Installations Only)
If you are installing a separate Oracle Unified Messaging system from your Oracle
eMail Server database instance, then you must configure Net8 to enable the Oracle
Unified Messaging system to contact the Oracle eMail Server database.
1. Add the following entry for the Oracle eMail Server database system to which
you want to connect:
<connect string> =
(DESCRIPTION=
(ADDRESS=( PROTOCOL= TCP)(HOST= <ES host server name>)(PORT= 1521))
(CONNECT_DATA= (SERVICE_NAME= <ES sid>)))
Example
esnode1=
(DESCRIPTION =
(ADDRESS = (PROTOCOL= TCP) (HOST= eshardware.acme.com)(PORT=1521))
(CONNECT_DATA = (SERVICE_NAME= orcl)))
2. Verify the modified tnsnames.ora file:
$ tnsping host
3. Verify that the Oracle eMail Server database tnsnames.ora file has an Oracle
Unified Messaging entry name that connects to the Oracle eMail Server
database instance.
