Multiple User Access for External Databases
Most external database products allow more than one user to
simultaneously access a database instance.
If you would like to give multiple users read-only access to a database
being used by EMS, there is no problem. However, do not allow these
users to modify a database being used by EMS. To prevent database
corruption, shut down the database before attempting to change any
data in the database.
External Database Tools and Options
If you are using external databases, 3Com does not recommend using the
maintenance tools and options bundled with EMS. These options are
limited and may not prove to be useful. Instead, use the database tools
and options bundled with your external database. For more information,
see the related documentation for your specific vendor.
If you are planning to run the EMS server on a workstation that has more
than one NIC and is configured to be on more than one network
(multi-homed), use this procedure to guarantee that the server binds to
an IP address on the desired management network.
To configure the EMS server for multi-homed support:
1 Using a standard text editor, open the server.properties file.
2 In the Client Interface IP config section, edit the ClientInterface field
according to your customized needs.
For example, on a workstation with two NICs and two unique IP
addresses:
address a = 1.2.3.4
address b = 5.6.7.8
If you want the EMS server to listen for client connections on address b
only, change the ClientInterface field to ClientInterface=5.6.7.8.
3 To enable the new configuration, comment out the ClientInterface field.
4 Save and close the server.properties file.
5 For these changes to take effect, stop and restart the EMS server.
