Products

• Protection Engine for Cloud Services
• Protection Engine for NAS

Issue/Introduction

The InMemoryFilesystemSize setting in Symantec Protection Engine (SPE) 8.1+ now has a maximum size of 128 GB. Previous versions had a maximum size of 4GB.

Environment

SPE 8.1+

Resolution

We recommend setting the InMemoryFilesystemSize and InMemoryFileScanCacheSize settings to 40% of the installed RAM on the scanner. These settings can be set using the following xmlmodifier commands:

xmlmodifier -s //filtering/Container/InMemoryFilesys​temSize/@value <value> filtering.xml
xmlmodifier -s //filtering/Container/InMemoryFileScanCacheSize/@value <value> filtering.xml

Replace <value> with the size in megabytes.

The xmlmodifier tool is located in <install dir>/bin on Linux and <install dir> on Windows. It should be run from the commandline.
