Planning For LiveSync in a Linux Environment


Verify the prerequisites needed to setup theCommServe LiveSync in a Linux environment.

Note: Identical software must be used for setting up the production and the standby CommServe hosts. Ensure that the Operating System and SQL Server version (including feature releases) are identical in the both the production and standby hosts.*

Operating System

CommServe LiveSync feature can be set up on all the operating systems supported by the CommServe server in a Linux environment.

For more information on the supported operating systems, see System Requirements for the CommServe Server in a Linux Environment.

License Requirements

  • CommServe Server

    No special licenses are required for setting up the CommServe server.

  • SQL Server Agent

    You must have two Microsoft SQL Server agent licenses, one for the production CommServe host and the other for the standby CommServe host.

    For more information on CommCell license categories, see License Administration.

Installation Packages*

The following Commvault installation packages are required for setting up the production and standby CommServe hosts:

  • CommServe Server

    Additional packages are installed by default during the CommServe installation. For more information, see the Additional Packages Installed with the CommServe section in Preinstallation Checklist for the CommServe Server in a Linux Environment.

  • CommServe Failover

    The SQL Server agent and the CommServe Failover package are automatically installed in a new instance. (No additional user intervention is needed.)

Firewall and Network Requirements

By default, this solution requires that all clients communicate with the CommServe server using a proxy. (By default, the SQL Clients installed in the CommServe hosts is used as the proxy.)

To facilitate communication between the clients and the CommServe, verify the following conditions:

  • Both the active host and the passive CommServe hosts can reach the tunnel ports that are associated with the SQL clients in both the active host and the passive CommServe hosts.

  • If the SQL clients are used as the proxy, verify that all the clients in the CommCell environment can communicate with the port and hostname of the SQL clients in both the active host and the passive CommServe hosts.

  • If a dedicated proxy is already set up and available in your environment, use this dedicated proxy to communicate with the CommServe server.

    Note: A dedicated proxy is recommended in environments with a large number of clients. (5000 or more approximately.)

  • To failover over to a CommServe host in the cloud, or if there is a firewall between the active host and the passive CommServe hosts, see Setting Up a Standby CommServe Using Port Forwarding Gateway Configuration.

    See Also: Network TCP Port Requirements.

* Any additional packages installed on the primary CommServe host, which includes other Commvault packages, or any third-party components, must be manually installed in the standby CommServe host. Also once the LiveSync operation is enabled, the LiveSync process will synchronize the information stored in the CommServe database from the production to the standby CommServe. For example, passwords and Additional Settings stored in the database. Any additional entities, such as third-party packages, scripts, registry keys, certificates, IIS settings, configuration files, etc. must be manually applied before or after failover as needed.
