2. Installation of ERA Server and ERA Console
2.1 Requirements
ERAS works as a service, and therefore requires a Microsoft Windows NT-based operating system (NT4 SP6, 2000, XP,
2003, Vista, 7, or 2008). Although the Microsoft Windows Server Edition is not necessary for ERAS to work, we
recommend installing ERAS on server-based operating systems for smooth operation. A computer with ERAS installed
on it should always be online and accessible via computer network by:
Clients (usually workstations)
PC with ERA Console
Other instances of ERAS (if replicated)
NOTE:
ESET Remote Administrator 4 fully supports installation over older versions (3.x, 2.x, 1.x) including data
migration.

2.1.2 Performance requirements
The server performance may vary depending on the following parameters:
1. Database used
MS Access database - installed with the server by default. We recommend this solution when servicing hundreds
of clients. However, there is a 2GB size limit for the database. Consequently, you will need to activate cleanups on
the server and define an interval (under
Tools
>
Server Options
>
Server Maintenance
) for removing old data.
Other databases (MySQL, MSSQL, ORACLE) require a separate installation, but may result in better server
performance. It is essential to use suitable hardware for each database engine (mainly ORACLE) following the
technical recommendations of its distributor.
If you choose ORACLE as your database solution, you must set the number of cursors higher than the
Maximum number of active connections
value (under
Tools
>
Server Options
>
Advanced
>
Edit Advanced Settings
>
Advanced
; the default is set to 500). The final number of cursors must take into
account the number of lower servers, (if replication is used) and cursors that are used by other applications
accessing the database engine.
Typically, the server's performance is higher when using external databases (i.e. installed on a different physical
machine).
2. Client connection interval
The client connection interval is set to 10 minutes by default in ESET Smart Security / ESET NOD32 Antivirus
versions 4.2 and later. If you need the client status to update more or less frequently than the default interval,
you can change the setting.Keep in mind that a shoerter client connection interval will affect server performance.
3. Average number of events reported by clients per connection
Any information sent from client to server is listed under the particular event (e.g. threat log, event log, scan log,
