Launch Kindlet from shell

[willysengewald]

I would like to launch a Kindlet from shell. I have set up a script to run with crontabs. Now in that script I would like to check for my Kindlet and, if it is not running, launch it. I've been searching the web for a shell command to do so with no luck.

My script currently writes information about running processes (ps -aux and ps -efl) into a log file but there is nothing about my Kindlet whatsoever even when it's running. It does not seem to be registered as a process.

What is the correct command for launching a Kindlet from shell?
How can I see if it's running?


I would be very thankful for any hint.

Hmm...
I would expect that it would be found as a child of one of the Java processes running (child of cvm maybe?).

Since the Java system is **essentially** a single-thread process (in that it only runs a single user application at a time), it may not have its own PID assigned.

Launching a Kindlet? Would probably have to call some entry point in the Java system.

Perhaps ixtab (or anyone else) could answer in more detail.

Simple answer: you can't. Not on a K4.

As knc1 pointed out, on the K4, the entire UI lives inside a single jvm instance. A Kindlet doesn't get its own process, but it's simply another class that gets loaded and "brought to the front" - all of this is happening inside the single cvm process.

Note that on the K5, you can do something like /usr/bin/lipc-set-prop com.lab126.appmgrd start app://com.lab126.booklet.kindlet/mnt/us/documents/YourKindlet.azw2 - but not on the K4.

Correction:
/usr/bin/lipc-set-prop com.lab126.appmgrd start file:///mnt/us/documents/YourKindlet.azw2

Many thanks for the fast response. I had the suspicion this could be the problem. So, I assume there is nothing I can do.

Is there any way of running a java application (or anything else), that is not a kindlet from shell or on boot up?

I could maybe get what I need purely with a shell script, but it will need some trying and testing.

Note that the K4 version does not have a lot of testing time on it.
If you have trouble with it on your K4, let us know (in that thread) and we will try to help with the problems.
