I'm a fairly experienced java and rpg programmer but this is my first
attempt on an RPG CGI-program that calls java.
Env:
i5/OS V5R4
Java 1.5
ILE RPG
IBM Httpserver powered by Apache
One cgi rpg-program has been running for many years, but was recently
extended with a few java classes and methods
This application works and runs like clockwork except:
My problem is that the *first* request to the cgi-program, after the
server is restarted, where the javapart is involved seems to time out
and return an error. Starting the jvm is the timeconsumer it seems,
because subsequent requests have very fast response times.
Is there a way to avoid the jvm startup cost when a user is involved?
Can the jvm be started up front? Seems like the server cgi-jobs does not
start until there is a request for the cgi-program.
Or maybe a timeoutvalue can be changed to enable the server to return a
normal response?
Any hints, comments and pointers are greatly appreciated.
Regards Rune
