> When we start Karaf with the karaf script on AIX we get the following error:
> {quote}
> user@host:/apps/user/pache-karaf-2.3.1/bin> ./karaf
> MAXDATA=0xB0000000@DSA
> karaf: JAVA_HOME not set; results may vary
> IBM J9 VM (build 2.6, JRE 1.7.0 AIX ppc64-64 20120322_106209 (JIT enabled, AOT enabled)

> When we checked on the IBM site we found this article: 
> http://www-01.ibm.com/support/docview.wss?uid=swg1IV29784
> If we look in the startup script we find:
> {code}
>     # For AIX, set an environment variable
>     if $aix; then
>          export LDR_CNTRL=MAXDATA=0xB0000000@DSA
>          export IBM_JAVA_HEAPDUMP_TEXT=true
>          echo $LDR_CNTRL
>     fi
> {code}
> And the IBM article states that you should avoid using IBM_JAVA_HEAPDUMP_TEXT variable
to not have that error message we've seen. The preferred mechanism for controlling the production
of
> Heapdumps is the JVM option: -Xdump:heap.
