Application-Server-Starter or
Self-Starter
When configuring a Virus Scan Server for ABAP systems, instead of an application-server-starter (started by the application server) you can install a self-starter (for example, started externally as a service under Microsoft Windows NT or a daemon under UNIX). In the case of application-server-starters, all components are on the same host. On the other hand, in the case of self-starters, the Virus Scan Server and the SAP Web AS can be on different hosts. This means that you can use a Virus Scan Server that is only available for a particular platform, even if the SAP Web AS is installed on a different platform.
Virus Scan Server on One or Two Hosts

During operation,
this division into application-server-starters and self-starters primarily
affects the Computing Center Management System (CCMS). You can monitor the
virus scanners in the CCMS (transaction RZ20), in the monitor Virus Scan Servers in the monitor set
SAP CCMS Monitors for
Optional Components. The following differences exist in this
case:
● Application-Server-Starters
In this case, the CCMS data collector automatically checks whether a configured Virus Scan Server is available. If this is not the case, the CCMS triggers an alert, and starts the Virus Scan Server again as an auto-reaction.
● Self-Starters
In this case,
although the processes are monitored by CCMS, they are not automatically
stopped or started. There is, however, a separate MTE class in CCMS for these
self-starters. You can assign an auto-reaction method to this MTE class
yourself to react to alerts. You can, for example, use the MTE class
CCMS_OnAlert_Email to send an e-mail or an SMS (see
Defining Automatic
Alert Notification and
Forwarding Alerts to
Alert Management (ALM)).

Ensure that
you secure your RFC connections with Secure Network Communications (SNC) as
described in the
SNC
manual.

● Virus Scan Server as an Application-Server-Starter
In the following case, you can use the application-server-starter as a self-starter:
The SAP Web AS kernel uses 64 bits and the external anti-virus product or the external Virus Scan Adapter (VSA) uses 32 bits.

To do this, use the field Instance Name, and create the 32 bit Virus Scan Server in a separate instance directory. More information: SAP Note 964305.
● Installing a Virus Scan Server as a Self-Starter
The self-starter is available to you as an alternative, if you cannot use the application-server-starter, for example in the following cases:
○ The SAP Web AS kernel uses 64 bits and the external anti-virus product or the external Virus Scan Adapter (VSA) uses 32 bits.
○ The SAP Web AS and the external anti-virus product support different architectures. For example, the SAP Web AS is installed on an AIX platform, but the anti-virus product is only available for Microsoft Windows.
