JRE
heap size for the
BlackBerry Proxy
service

The

JRE

default installed heap size is sufficient for up to 5000 devices supported by your

BlackBerry UEM

server, under normal conditions. However if there are conditions in your environment or workload that result in requests queuing at the

BlackBerry Proxy

service during peak times, you must increase the heap size.

To increase the

JRE

heap size of the

BlackBerry Proxy

service, use the

Windows

Registry Editor (regedit command). The HKEY entry in the registry for

BlackBerry Proxy

is:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\BesGPS\Parameters\Java

Max heap memory for each BlackBerry Proxy instance
Number of devices	Native Java setting (-Xmx)	Registry key: JvmMx (decimal value)
Up to 5000	2400m (default)	2400 (default)
For some queueing	3072m	3072
For significant queueing	4096m	4096

After you change the setting, restart the

BlackBerry Proxy

service.
