How to increase Zephyr memory allocation in Windows systems

Created on


Zephyr server sees poor performance on larger systems during certain times


Java applications like Zephyr run in a "Java virtual machine" (JVM). When started, the Java virtual machine is allocated a certain amount of memory. By default, Java virtual machines are allocated a small portion of the total system memory, no matter how many gigabytes of memory your server may actually have available.This may be inadequate for medium to large Zephyr installations, and so this needs to be increased


Steps to increase the default memory:

1.       Click Start, then *Run..." and type regedit

2.       In the registry editor, navigate through these steps

HKEY_LOCAL_MACHINE -> SOFTWARE -> Apache Software Foundation -> Procrun 2.0 -> ZephyrServer -> Parameters -> Java

Here you will see an entry for JvmMx, which is the "maximum memory" setting

(For 64-bit machines, you may need to navigate to: 

HKEY_LOCAL_MACHINE -> SOFTWARE -> -> Wow6432Node -> Apache Software Foundation -> Procrun 2.0 -> ZephyrServer -> Parameters -> Java)

3.       Double-click JvmMx to edit, change the Base to "Decimal" and adjust the value as necessary.

4.       Click "OK", close the registry editor and restart the Zephyr service (under Start -> Zephyr -> Server Admin -> Stop .... then Start -> Zephyr -> Server Admin -> Start
