[. . . ] Be sure to use the same machinekey string on all servers. Maintenance Users should regularly backup the SQL database. The interval between backups defines the maximum time window over which data would be lost. Typical installations would perform full nightly backups of the database. Please see Section 0 Backup and Recovery of the TMS database of this document for additional details on how to perform backups and restores of the Cisco TMS database. As multiple Cisco TMS servers are being used, administrators should periodically check that their file synchronization process is still functioning to ensure smooth cut-over in the case of having to use a warm spare. Cisco TMS redundancy configuration and overview Page 18 of 32 Cisco Redundancy Models for Cisco TMS Upgrading TMS All Cisco TMS servers accessing the same database must be running the same Cisco TMS version. When upgrading between Cisco TMS versions, there will be inconsistencies between different servers as each is upgraded so extra steps are required when performing Cisco TMS upgrades or patches. When performing a Cisco TMS upgrade, the following steps must be followed Plan an upgrade during a time window when Cisco TMS can be made unavailable to users as Cisco TMS will be unavailable during the duration of your upgrade. On your primary Cisco TMS server, start the installer for the Cisco TMS upgrade as normal. During this process, any updates to the SQL database will be performed. Installation may require a reboot of the server. After the reboot, go into Services component of Computer Management on the server, manually stop all services whose name starts with Cisco TMS and the WWWPublishingService service. Proceed to the next server, and start the installer for the Cisco TMS upgrade the same as you did on the primary Cisco TMS server. The installer will likely restart the Cisco TMS services and WWWPublishingService and may require a reboot of the server. After the reboot, go into Services component of Computer Management on the server, manually stop all services whose name starts with Cisco TMS and the WWWPublishingSevice. The services may also be configured for automatic startup. Rightclick on each of these services and select Properties. On the General tab of each of the services you stopped, set startup type to Manual. After upgrading all Cisco TMS servers, log into the primary Cisco TMS's Windows console and restart all Cisco TMS services and WWWPublishingService. Secondary servers should all still have their Cisco TMS and WWWPublishingService stopped and set to manual startup. Log into the Cisco TMS website, go to Administrative Tools>Configuration>Network and change the Cisco TMS Server IPv4 Address (Local): address to the IP address of the primary Cisco TMS server. Upgrades will erase any changes to the IIS web configuration files, including the viewstate machine key and method defined during installation. Repeat the viewstate key generation and installation steps outlined in the Installation section on each of the upgraded web servers. Model Summary Immediate fail-over available. [. . . ] If a server fails, there are limitations to how active calls being handled by that server will be handled. Calls that have not begun the initialization phase or are executing on other servers will not be affected. If the primary Cisco TMS server for call launching is not active, another active Cisco TMS server will start the conference after 60 seconds. If no secondary server is running when the call is scheduled to start, a check is made when a server does come up for any call that has not started that should have been and will start them Conferences that are still initializing and have not finished connecting will not automatically be started.
