Appendix B.
Redundant Cisco TMS Servers
If your Cisco TMS installation includes multiple Cisco TMS front-end servers in a redundant or fail-
over scenario, some additional care must be taken when installing and configuring the Cisco TMSXE
Integration. This section will cover any to be aware of to ensure the Cisco TMSXE Integration will
continue to work in your redundant or fail-over scenario.

Pre-Installation

The Cisco TMS side service account is normally created by the installer as a local Windows user.
Because the Cisco TMSXE Integration should be able to use any of the Cisco TMS servers, a domain
user account should be used instead so the credentials will work on any of the servers.
1.
Create or designate a Domain user account you will use as the Cisco TMS side service account.
Using this account, open a web browser and log into the Cisco TMS web interface so a user
profile will be created for the user. When complete, close your browser.
2.
Open a web browser and log into your Cisco TMS server with a username that is a Site
Administrator. Edit the service user's profile under Administrative Tools >User Administration
> Users. In the account's profile, set Exchange Integration Service Account to Yes. Set the user's
email address to what will be the Exchange Service Account's email address. This normally
would be tms-service@<SMTP Domain>
that has the Book on behalf permission set in the Group Permissions. Save the changes to the
user's profile and close your web browser.

Installation

The normal installation steps can be followed taking note of the following specifics:
When prompted to Select the Service Account for TMS, select the option I have created a service
user on the TMS server and enter the credentials of the Domain user you designated to use as
the service user. For the Cisco TMS address, be sure to enter the address that is shared by your
Cisco TMS servers (the DNS hostname, or load balanced address, etc). Do not select the HTTPS
option unless all servers have been properly configured for HTTPS operation.

Operation

There is no change in operation compared to a traditional Cisco TMS. By using the shared or load
balanced address for the Cisco TMS server in the Configuration Utility, the integration will connect to
a live Cisco TMS server the same as regular users do.

If unsure of this address, enter any valid email address and you can come back and update the user's TMS
profile with the correct address after the TCX Installation has been completed and the TMS-Service account is
created.
