I came across an article on Search400, regarding opening up a windows app from an as/400 CL program. It uses the runrmtcmd. I have attached the article. I have started the runrmtcmd on my PC under local user. I went into my user account, and changed my password to make sure it matched the one I am using on the runrmtcmd. I retrieved my IP address by using the ipconfig command. However when I run the remote command I am getting required password missing or invalid. We do this in one other place where I run a remote command on another server that runs an executable in batch mode on that PC. I tried changing the command to run a word app on that pc. I do not get an error but my job just hangs. This article makes it sound like you can start up for example a word document from an as/400 session and actually do changes/ creations on it. Has anyone done this? Am I missing something? Angela Wawrzaszek Programmer/Analyst Nucor Steel Auburn wawrzaszek@xxxxxxxxxxxxxxx (315) 258-4205

Tip for launching a Windows app from the AS/400

Tip for launching a Windows app from the AS/400
provided by Ron Turull and published in the August issue of
Inside Version 4.
Remember when you could launch a DOS program from an AS/400.
You can still do it if you're running DOS-based PC Support.
With IBM's final acceptance of Windows, however, most of us
have moved far beyond those days and, for better or for worse
(I'm never quite sure which one it is), are firmly entrenched
in Windows-land. So we may now find ourselves with a need to
launch Windows programs from an AS/400.
For example, on a customer record screen on the AS/400, you
may want to provide a function key to allow the user to write
a letter to the customer. Since PC word processors are far
superior to anything found on the AS/400, you would probably
want to launch Word or some other PC word processor using the
following steps:
Copy the customer's name and address to a DLS (document
library system) document,
Launch Word for Windows, automatically opening a form
template, and
Automatically running a Word macro to open the DLO document
and copy the customer information into the proper places on
the form.
It can be done. And, it is a whole lot easier than launching
DOS programs. The solution is the fairly simple RUNRMTCMD
(Run
Remote Command), not to be confused with the SBMRMTCMD which
allows you to submit a CL command to another AS/400.
Don't try it yet!
Before you race to your nearest PC to try out the Run Remote
Command command, be aware that you have to launch a daemon
program on the PC first. The name of the program is
CWBRXD.EXE
and, once executed, it sits in the background and waits for
incoming commands. When it gets one, it executes it. On a
side
note, ironically, the CWBRXD.EXE program is a DOS program
(don't ask me why).
Also, you have to configure Client Access to accept incoming
commands. To do this, press the Start button and select
Programs. Then, open the Client Access 400 folder and select
Client Access Properties. On the properties page select the
Remote Command tab. Here you can add which users can submit
commands to the PC.
To add a user, press the Add button. To allow all users to
submit commands to the PC, specify an asterisk (*) for both
the System and User ID fields (leave the password fields
blank). Otherwise, add only the users who you want to submit
commands to the PC.
If you check the "Automatically start incoming remote
command"
checkbox, the CWBRXD.EXE daemon program will be started
automatically when you open a connection to an AS/400.
Alternatively, you can stick a shortcut to the CWBRXD.EXE
program in your Startup folder.
2 protocols supported by the RUNRMTCMD command
The RUNRMTCMD command supports two communications protocols,
SNA and TCP/IP. You must to know which one the PC you'll be
submitting commands to is running. To determine which one a
PC
is running, open the Client Access 400 folder again (as
described above) and select AS400 Connections.
On the resulting screen, in the right-hand panel, right-click
the connection configuration the PC is using. Select
Properties on the pop-up menu. The Connection type field on
the AS/400 Connection tab will show you the protocol the PC
is
using. Make a note of it because you will need it on the
RUNRMTCMD command.
How to use the Run Remote Command command
Now that you have your PC configured, sign on to an AS/400
(you don't necessarily need to use the PC running the
CWBRXD.EXE daemon program - in fact, you can use a dumb
terminal). On a command line, type in "RUNRMTCMD" and prompt
it with F4.
On the Command parameter, enter the PC command you want to
run. For example, on my PC, to launch Microsoft Word, I use
the command
C:MSOfficeWinwordWINWORD.EXE.
The Remote location parameter is in two parts, the "name or
address" of the target PC, and the communication "type"
(i.e.,
protocol) the PC is using. If the PC is using SNA, specify
its
remote location name for the "name or address" field. You may
have to prefix the name with the network ID of the PC if it
differs from the AS/400's local network ID (use the DSPNETA
command to determine the AS/400's local network ID). Then,
obviously, specify *SNA for the Type field.
On the other hand, if the PC is running TCP/IP, specify the
PC's IP address for the "name or address" field.
Alternatively, if the PC has an entry in the AS/400 host name
table, you can specify its host name (see the CFTTCP command
for more information on the host name table). Either way,
you'll need to specify *IP for the "type" field.
For the Remote user ID parameter and the Remote password
parameter, you'll need to specify the user ID and password
configured on the PC. If you configured the PC to accept
commands from any user, then leave the defaults for these
parameters, *NONE.
Here is an example of the RUNRMTCMD command:
RUNRMTCMD
CMD('C:MSOfficeWinwordWINWORD.EXE')
RMTLOCNAME('192.168.10.7' *IP)
The IP address problem
Don't get too excited yet! One of the common uses of the
RUNRMTCMD command is to launch a Windows application from an
AS/400 program on the PC the user is using. The last clause
in
the previous sentence is the operative one. When using
TCP/IP,
how do you determine the IP address of the PC the user is
using?
The answer is there really is no way of doing so, at least
not
that I have found. There is a workaround, but it takes
commitment, diligence, and time. The first thing you need to
do it get your users on a telnet client that supports device
naming. Client Access's PC5250 works fine.
The trick is this: Give each user's telnet configuration a
unique device name. When they start a session and sign-on to
the AS/400, their interactive job will have the same name as
the device name. Part two: Add all the device names that you
assigned to the AS/400's host name table. Use the ADDTCPHTE
command to add the names. On the Internet address parameter,
specify the IP address of the PC and on the Host names
parameter, specify the device name. Warning: Doing this
creates a conflict that prohibits the use of DHCP.
Once this is done for each user, you can use the RTVJOBA
command to retrieve the name of the job. If you properly
configured the host table, the job name will be the same as
the host name. Then you can specify the job name for the
Remote location parameter on the RUNRMTCMD command.
No addressing problem for SNA
SNA doesn't suffer from the "addressing" problem because you
can easy determine the remote location name from the device
description (which, again, has the same name as the job
name).
Just use the Retrieve Device Description API (QDCRDEVD) and
format DEVD0200 to get the remote location name and, then,
plug it into the Remote location parameter.
RUNRMTCMD does DOS programs, too
You can also launch DOS commands and programs using the
RUNRMTCMD command. However, if they have any output, it is
written to an AS/400 spool file. Therefore, interactive DOS
programs aren't an option. For example, you can't launch your
old DOS version of Word - not that you would want to anyway.
