Near Ilan. Small L The Work with ICAP Servers screen appears: Work with ICAP Servers Server Definitions from the Antivirus Definitions and Refresh screen ( STRAV > 21). To use an ICAP server, the Type of virus scanner Local/ICAP field on the Antivirus General Definitions screen ( STRAV > 81) must be set to ' 5' (as shown in Setting General Definitions). To define ICAP servers, you must have licensed the ICAP client. NOTE: The ICAP Client is an add-on to Antivirus and requires an additional license. The local IBM i CLAMAV engine remains in silent mode (effectively off) and uses a very limited percentage of CPU. When you use an external ICAP server, the main Antivirus subsystem, ZANTIVIRUS, only runs two or three monitoring jobs and one to four real time scanning jobs. The ICAP Client can communicate with any ICAP server. The portion of the IBM i CPU that would have been used for virus scanning becomes available for other purposes. Scan time is faster – by twenty times in some tests. Using ICAP ensures that your IBM i is always protected without a performance drop. Those servers send responses back to the iSecurity ICAP client clearing the object for use or flagging it as infected. The file can be simultaneously scanned by multiple ICAP servers.

When iSecurity Antivirus intends to scan an object, with the addition of the ICAP Client, it passes the file to the ICAP server for processing. Using ICAP reduces the load that virus scanning can demand from IBM i servers by distributing the CPU-intensive part of virus scanning onto separate external ICAP servers. Virus scans tend to be CPU-intensive because they scan millions of possible virus signatures. With the ICAP protocol, Antivirus scans your system's files for viruses using a remote system.
