Adding More Memory to Protege 4

In Progress


Non-OS X Operating Systems

Edit the Protege.lax file with a text editor and change the initial and maximum heap size. Unfortunately you can only do this in bytes so you need to track the number of zeros:

#   LAX.NL.JAVA.OPTION.JAVA.HEAP.SIZE.INITIAL
#   -----------------------------------------
#   initial heap size

lax.nl.java.option.java.heap.size.initial=800000000


#   LAX.NL.JAVA.OPTION.JAVA.HEAP.SIZE.MAX
#   -------------------------------------
#   maximum heap size

lax.nl.java.option.java.heap.size.max=800000000

OS X

Editting the Info.plist

Navigate to the Protege 4 application in the finder and right click on the Protege 4 owl editor application. Select "Show Package Contents".

Show Package Contents

A new finder window will come up and in that window navigate to Contents and edit the Info.plist file in a text editor (alternatively you can use the os x plist editor by double-clicking if it is installed). Near the bottom of this file there are the lines

            <key>VMOptions</key>
            <array>
                <string>-Xms200M</string>
                <string>-Xmx200M</string>
                <string>-Dosgi.clean=true</string>
            </array>

Modify the -Xmx and (optionally) the -Xms lines to the desired amount of memory

            <key>VMOptions</key>
            <array>
                <string>-Xms800M</string>
                <string>-Xmx800M</string>
                <string>-Dosgi.clean=true</string>
            </array>

Users with the zip file distribution

Edit the run.sh (or for windows users the run.bat) file and modify the -Xmx line:

java ${CMD_OPTIONS} -Xmx800M -Dosgi.clean=true  -jar org.eclipse.osgi.jar
