The IBM iSeries (System i) JDK Juggle
Read Time:34 Sec
While installing the Oracle Server Manager agent, we learned some interesting little Java tricks on the IBM iSeries. They probably work on all platforms, but I don’t know for sure and I’m not going to take the time to test. Also, these tips are for OS400 V5R4.
- How do you know which version of JDK is your systems default?
runjva class(*VERSION)
- If you have more than one JDK installed, how can you force it to run a certain version?
runjva class(*VERSION) prop((java.version 1.5))
These couple little tricks may seem pretty simple to you.
However, for someone without Java experience, especially on the iSeries, they can be very helpful.
