RE: How do I keep JVM open after first call?

Maybe open a connection at start of day
and run weight function as "never ending" ?

Thanks for the response folks.



I have included a debug log below that I ran the other day.



I'll try to give more detail now. I have a CL calling a Java program that
is doing a sockets to a weight scale on my network. The Java program
retrieves the weight fairly quick. The program then opens a connection to
the iSeries and does a CHGDTAARA command to put the weight in the data area.
I then, in the CL, retrieve the weight and the program goes on its way.
As you can see towards the bottom of the log, it takes 5 seconds for the connection to the iSeries and then 5 more to do the CHGDTAARA.



Sorry if this is NOT the way to post log files...I searched for the a way to post the text file in here instead, but I didn't find anything.
