Does anybody know how to fix JNAUtils error on AIX?

I have the following  configurations:

AIX powerpc

IBM java 8

voldemort 1.6.0

thanks

See error:

AIX case is not handled. You need to handle the AIX case in this file

https://github.com/voldemort/voldemort/blob/master/src/java/voldemort/utils/JNAUtils.java

Thanks,

Arun.

Hi Arun,

I added the following lines to skip mlockall for AIX. What is the impact for skiping mlockall on AIX? 

In JNAUtils.java

 public static void tryMlockall() {

        try {

            if(isOperatingSystem("windows"))

                return;

            if(isOperatingSystem("aix"))

                return;

Is there a way to make mlockall work on AIX?

thanks

Thanks,

If you can't do mlockall, disable the swap space on the OS and both has the same effect.

Thanks,

Arun.
