[Php-java-bridge-users] Increase java memory

[Robert H. <rob...@gm...>]

I am getting out of memory errors for java.  I am using the java vm
lauched by apache method (I originally used the seperate vm method,
but after I stopped it I couldn't get it started again, and this is a
live server that I cannot reboot).  Can anyone tell me how to modify
the command line that java is started up with so that I can give it a
higher upper limit for memory?

God Bless,
Robert Hostetter

You can increase the memory that the JVM uses (32 MB
is standard) with the -Xmx switch.

You must start the JVM as a separate process, though,
because the bridge currently does not pass additional
options to the VM.  

Please type 

  php -i | fgrep java

and paste the java command you see there to the
command line and edit it so that it includes the 

   -Xmx256M  

switch.

For example:

 java -Xmx256M -Djava.classpath... \
               -Djava.library.path=... \
               -Djava.awt.headless=true \
          JavaBridge \
              /tmp/.my_java_bridge_socket 3 ""

Please look up the correct -D values from the output
of the php -i command.  And then edit 
/etc/php.d/java.ini and set the java.socketname to
your socket: /tmp/.my_java_bridge_socket

Another option would be to edit the
"/usr/bin/php-java-bridge" shell script which is used
to start the bridge as a system service.  But you must
be root to do this.


> I couldn't get it started again

Which error message do you get?  Probably the system
/usr/share/java/.php-java-bridge_socket is in use?
