Installing Multiple Instances of IWSVA

You can install multiple instances of IWSVA to handle high traffic-volume. When running more than one IWSVA, there are a few things you need to know:

• You need to designate one instance of IWSVA as "parent" and all other instances as "children."

• If one instance of IWSVA is installed as stand-alone, then all instances in the IWSVA cluster must be stand-alone. Likewise, if one instance of IWSVA is installed as an ICAP server, then all instances of IWSVA in the cluster must also be installed as ICAP servers.

• In a multi-server environment IWSVA can and should use a common database to store the following:

• URL Blocking rules

• URL Filtering categories and policies

• URL Filtering approved lists

• Logs (e.g., Report data)

• To share report and log data between the servers, choose "Database only" for the "Write logs to" option in Logs > Log Settings > Reporting logs.

• Unless you have Trend Micro Control Manager installed, IWSVA configuration files are not shared among multiple IWSVA servers. Each IWSVA will store its own configuration for the following files:

• Scan options, schedules, and notification messages

• Proxy server, LDAP, and other settings

• Update schedules

• Log in password

• User ID method

• Individual scan engine and virus pattern files

• Note: Trend Micro recommends that you use exactly the same settings for all IWSVA servers in one server farm.
