Dear Friends, Hope that Every One is fine.
How do I create a DDM DATA AREA, when I am creating one I don’t know what to give for these parameters like?  

RMTLOCNAME
DEV        
LCLLOCNAME
MODE      
RMTNETID  

When I went to IBM Help those are all not clear.

I managed to Create with some default values on those parameters, then when I try to do

DSPDTAARA DTAARA (XXXX/SUDTAARA) SYSTEM (*RMT)
Remote location XXXXX for program device DDMDEVICE was not found.
Cannot establish DDM connection with remote system.                
Operation on DDM data area SUDTAARA in XXXX failed.            


Can any one please tell me Step-By-Step of how to do? Will be great help.
Thanks in Advance.

Well, first make sure you're running SNA in your network since DDM data areas don't work over TCP/IP. (Note that *ANYNET can encapsulate SNA over TCP/IP if it's configured to do so.)

Next, make sure that the desired remote location has been properly configured and the SNA connection is active. This involves a controller and a device description.

Perhaps the first place to start for a quick look is simply the WRKCTLD command. The various *APPC controllers that appear in the list are the ones you'll be looking at. Most likely the controller name will match the remote location name.

Take option 8=Work with status for the appropriate controller. If its status is ACTIVE and it has a device attached that's also ACTIVE, you've got a good chance of an active connection to the remote location that you're interested in. The devices attached to the controllers are where the "remote location" name will be set.

If you can't find an active controller/device that points to the location you want, then we've found at least part of your problem.

(Most often, a simple STRPASTHR command to the desired remote location can answer whether the SNA route is active.)

Dear tliotta,

Since I am not the Networking Person or 400/Admin all the things
you have given all not familiar to me. Any way I have check my machine both
Source and Target I have found out the followings. I there any way you can give
me the step-by-step how to do this from the start, assuming that from
CRTCTLD ....... DSPDTAARA , that will be great help ,
I know I am asking TOO MUCH! But I am honestly trying to Complete this.



WRKCTLD command result in Source:( Whwer i have to create *DDM)


Mode/status . . . . . . . . . . . . . . :   SNAME        Started
Device/status . . . . . . . . . . . . . :   XXX          ACTIVE
Local location/network ID . . . . . . . :   XXX          APPN  
Remote location/network ID  . . . . . . :   YYY          APPN  



WRKCTLD command result  in Target:( Where i have My DTAARA )
                                                                 
Mode/status . . . . . . . . . . . . . . :   SNAME        Started  
Device/status . . . . . . . . . . . . . :   YYY              ACTIVE  
Local location/network ID . . . . . . . :   YYY         APPN    
Remote location/network ID  . . . . . . :   XXX      APPN    

Creating Data-area:

   CRTDTAARA DTAARA(MYDA/Mylib) TYPE(*DDM) RMTDTAARA(MYDA/Mylib)  
           RMTLOCNAME(YYY) DEV(SNAME)  

MSG:Data area MYDA created in library Mylib.

                                             
I All ready have a Data-Area with same name in that Remote Location(yyy).



DSPDTAARA DTAARA(MYLIB/MYDA) SYSTEM(*RMT)

Message . . . . :   Not able to allocate objects needed for file QCNDDMF in
                    library QSYS member or program device DDMDEVICE.

Message . . . . :   Cannot establish DDM connection with remote system
Message . . . . :   Operation on DDM data area MYDA in MYLIB failed.
                       

RESULE OF STRPASTHR:

STRPASTHR RMTLOCNAME(YYY)
Message . . . . :   APPC failure. Failure code is X'0009000000000000'.

Although you showed the controllers, there's no indication of any devices associated with them. The device descriptions will be where the Remote Location names will be assigned.

Sorry there was such a time gap. My first response was intended as an overview and I figured someone else could track down any specific details and really help fix your problem. But no one else showed up and no device info was posted either. If my last response helped focus you on the device or if you worked through it on your own using my discussion as a guide, then all is well.

But if not, then keep in mind that you are spending points for answers. Maybe those points cost you time and effort, maybe they cost cash; but they did cost.

Don't hesitate to post followup questions for clarification in the thread. The more points offered, the more info should be in the thread. Strive to get your value.

Hi TOM , you Helped me for my thought process where to Start  more over I have used this link

http://www.itjungle.com/fhg/configure-objectconnect-and-anynet.htm

to configure the *anynet server , then I have tried for STRPASTHR , and that worked , then I used your Help
that all together I got that Working , so you are the one put me in right direction thanks for that .

Since I am not a Networking person I had little problem of understanding the whole thing even though
I fixed this issue . Can you suggest me where I have to start to understand the Networking issue with respect to AS/400
any Link info will help me .

thanks Tom .
