Re: Managing SMTP jobs -- MIDRANGE-L

Hi Kevin,

The UK box is at V5R1. I think we are using SNDDST, but will check with theprogrammer and let you know! Will check out 'open relay'...

Thanks for your suggestions,

Clare

Hi Clare,

I am not an SMTP expert, nor do I play one on TV, but here are some things
to think about:

1. Is one or more of your boxes an open relay? ie accepting incoming email
from outside then passing it on. Searching midrange archives for "open
relay"  should show you how to identify and stop this.
2. Is there some mail "stuck" in SMTP? Try a cold restart, STRMSF
MSGOPT(*CLEAR) when there should be no pending emails.
3. Are you using SNDDST, qtmmSendMail, Javamail or roll your own?
4. What OS level is the UK box?
5. Anyone else? Bueller?
Regards,

Kevin Wright

Subject: Managing SMTP jobs

Hi all,

Does anyone have any tips for managing SMTP jobs that take a
lot of CPU? My
client has systems in 18 countries that are trying to send
messages to/from
each other's ERP systems. They are on 12 boxes, all at
different levels of
OS from V4R3 to V5R2 (yes, I know!!). On the UK box (V5R1)
the problem of
SMTP jobs taking too much CPU was solved by a PTF, however
this has not
worked on the other boxes. Or maybe it is still a 'hidden'
problem on the UK
box, which is rather big compared to the others!
Applying latest PTFs has not helped, is there a strategy that
will help,
such as cleaning out the queues regularly or something???
What do other
people do? Is there a software or tool out there that will
help? Should they
be doing this another way than SMTP???
Grateful for any suggestions,

cheers,

Clare
