Re: calling a program v using a SRVPGM

Fair enough.  A little back story to set the starting point.  I like the platform; been programming on it for 45+ years.  I would, by any measure, be classified in the middle of the programmer pack; not a guru, but not a dunce either. What is really easy for lots of you guys is not easy for me; I struggle with a lot of the concepts.  I figure that since I am middle-of-the-pack and struggling, then there are plenty of other middle-of-the-pack struggling, too.  So that's where I play.  I have a lot of sympathy for the guys and gals who have been beaten down over and over by the newest great thing that brings them nothing but misery and humiliation.  Maybe I can ask the stupid questions and help the platform move the rest of us into the 21st Century.

So, as to this particular rabbit trail...  I got an email with a tracking number and discovered a package was delivered to me at my front door at 12:56pm on Dec.24th.  Well... errr...  no it wasn't.  I called the post office.  A very short wait and a very courteous person answered. I explained the problem, he said.. "What is your email address?"  I told him.  In a few seconds I have an email with a map and an orange arrow pointing to a place near me, but not me.  He says thats where it was delivered.  He'd take care of it.

Frankly, I was flabbergasted.  My first thought: "Damn!! How would I do that on an AS400?"

So that's the backstory. More or less.  (oh.  yes.  next morning, knock on the door, very embarrassed mail lady handing me my re-taped package.)

Do I like 5250?  Yes.  Do I believe it'll make a comeback?  Sure I do.  Right after OS/2.

That's why I want to know more about web services as opposed to band aids on simulated token ring.

huh? Wait a minute... Am I reading this right?

In fact, the end game for this project is to be able to do just that; to
go to various i-series ip addresses in the network. That seemed a
bridge too far for my skills but... really? It could be done?

The nature of the business problem tends to guide us toward an
appropriate architecture. There are multiple ways for an RPG program
on Server A to cause a program on Server B to execute. Off the top of
my head:

Sockets (TCP/IP - you write both sides)
SQL (stored procedure / CONNECT TO / ODBC / JDBC)
RPC (Remote Procedure Call)
DDM / SBMRMTJOB
Web service / HTTPAPI / CGIDEV2

Please describe the scenario you're looking to handle. Are there
multiple servers that need to be contacted more or less dynamically?
Perhaps their names and contact times are in a table, and there's a
central server that polls the sister servers for the purpose of
aggregating data like sales history? Is it a pair of servers where one
is the user-facing side and the other is the database server side, and
the UI side needs to push and pull data? Is it a data warehouse that
gets data pushed to it from several geographically dispersed servers?
I believe that 'how do I...' will be easier to answer after we've
heard 'I want to...'
