When trying to use a remote DATA QUEUE the send and receive data queue commands failed giving : Service with protocol tcp not found. Cannot establish DDM connection with remote system. Operation on DDM data queue DTAQFIFO in TESTLIB failed. Remote location MYAS400 for program device DDMDEVICE was not found. I tested the data queue programs locally and worked well. Remote DDM for physical files are also working well. The remote AS400 (MyAS400) is in a local TCP/IP network. To create the DDM dataqueue this command was used : CRTDTAQ DTAQ(TESTLIB/DTAQFIFO) TYPE(*DDM) RMTDTAQ(RMTLIB/DTAQFIFO) RMTLOCNAME(MyAS400)

Thanks. We'll let you know when a new response is added.

Hi,

You probably need some extra TCP “servers” running on both machines. You’re certainly going to need the DDM server sunning :-

STRTCPSVR SERVER(*DDM)

The TCP servers on the AS400 are the equivalent to TCP services. It’s also worth checking that you have a connection that works to the other machine using the location name, you can try pinging the location name :-

PING MyAS400

Or telnetting to the other machine :-

TELNET MyAS400

When you get to the signon screen press the attention key and use option 99 to return from the telnet session.

Regards,

Martin Gilbert.

    Thanks Martin, TCP/IP commnication between the 2 AS/400 is working well. In fact I can do CPYF for DDM remote physical files , it is only for the remote data queues that this error is being produced.

    Hi, I assume that you've also created the 'normal' data queue on the target machine (RMTLIB/DTAQFIFO)? Machines are on same level of OS - which level? Regards, Martin Gilbert.

    Hi Guys, I am also having a similar problem. We have move to v5r4m5 on most of our boxes and have gone to Power 6 so SNA DDM no longer supported by IOP less cards. We are now using the Enterprise extender to use DDM between 2 partitions. This works fine for the 2 v5r4m5 partitions. However we have a 520 running v5r3m0 and have had to configure anynet to use ddm files. The strange thing is as SBCHenry says i CAN RUN A DSPPFM OR CPYF USING A ddmf BUT IT doesnt work for DDMDTAARA or DDMDTAQ's. Did you find a solution SBC HENRY? Or Martin? Cheers Marcus
