RE: Help: crtjvapgm running >7 hours ?!

David,

Hey, thanks for writing!

I started the CrtJvaPgm job at 2:40pm, 7/11/00, in an interactive client
access session dialed in through my ISP from home using Client Access
Express. We have a AS/400 600e 2129 processor with 196mb and 12gb
disk--68%in use.  

I had 4 sessions going and was watching the cpu usage and trying to see some
indication of activity other than sluggish system.  Working with the job
showed no disk activity to speak of, no messages in the job log--except the
initial command, no print job in progress, so I began to wonder if it was
really doing anything.  

After 7 hours I started to get worried and put out the email.

Sometime around 12:30 am (10 hours) I was reconsidering killing the job when
my sessions started dieing as did my Ops Navigator connection.  When I then
pinged the AS/400 and got no response I started to get worried. I had not
lost my network connection because I could ping our router and other servers
but no 400.  I rebooted my PC and tried again anyway to no avail.  At which
point I hopped in the car to drive over to the college and see what was
going on.  No sign of trouble at all.  Local client access worked through
tcpip; ping worked locally and remotely through a login to the ISP and back
again.  When I got home I was again able to connect normally.  No system
operator messages.  

I have no clue what happened to my connection, but 10 hours is more than
"several".  Does it seem possible that it was almost done perhaps when the
session died?  At some point I tried a dspjvapgm from another session and
that session remained input inhibited.  I assumed the compile had the jar
file locked, but when I worked with the job it showed no job locks on that
file.

I assumed the compile failed.  Running Dspjvapgm on jt400.jar just now
returned:

 Java program creation information:

I don't understand why the 7/10 date.  I did nothing to specifically compile
the program then.  It was yesterday, 7/11/00 that I tried it.  But clearly
it is not optimized to 30.

SO, ANYWAY, I should be real brave some FRIDAY night and submit it to batch,
eh?  And it won't blow away my TCP/IP... Could there be some other problem?

I did have the HTTP ADMIN and Websphere instances up when I started the job.
After a few hours when it took so long, I shut down the http server thinking
there might be a conflict.   

Your help appreciated and any further thoughts welcome!

Regards,

Ravi

Sorry but yes it can take that long.  Depending on the speed of your AS/400
it can take several hours.  Since It will take all available CPU time I
usually do the task as a submitted (batch) job that runs overnight.

I decided to "make my programs run much faster" with

crtjvapgm clsf('QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar')
optimize(30)

as recommended by David Wall.

This command has now been running for 7 hours, using all available cpu
time.
Is this normal?  How long should it take??!

Thanks,

Ravi
