Re: HiperSockets Setup
Make sure you use the 2007 version of the Hipersockets Redbook. I was never able to get it to work with the 2002 edition.

Hi Yes, I have the 2007 version! Any Idea what the error message means?

Re: HiperSockets Setup
All you have provided so far is the message ID, which is not in current doc.. It would be most helpful if you could paste the complete message so that we might have a little more to work with.

Re: HiperSockets Setup
On Wed, 4 Jun 2008 17:44:05 -0500, Mike Walter [EMAIL PROTECTED] w rote: Terry, Looking in the z/VM 530 TCP/IP Messages and Codes manual, there's no DTCOBE0055E message listed. OBVIOUSLY, it must be self-documenting! That typed with disapproval of self-documenting messages dripping fro m the keyboard. In fact there's only 1 (count 'em, ONE) numbered OBEYFIL E message, and three unnumbered messages. DTCOBE0055E must be newer than the -02 manual I'm looking in. Could you please copy/paste the specific message you are seeing? I am setting up HIPERSOCKETS for the first time and I am dealing with th e syntax of the TCPIP PROFILE for the first time. I am using the HIPERSOCKETS Implementation Guide Red Book to walk through this. I made the changes to the PROFILE TCPIP and the SYSTEM DTCPARMS file. I am tryi ng to do the OBEYFILE PROFILE TCPIP and I am receiving a DTCOBE005E error message. I assume it is some kind of syntax error in the PROFILE but I cannot find the description of the error message. Anyone know where I might find it? Interesting little game of telephone here. DTCOBE005E - DTCOBE0055E. B ut I could find neither one in LookAt. z/VM TCP/IP has numerous undocumented messages. Every time we complain we get the same response which would you rather have us do, document messages or write new code. Open an incident with IBM. And include the full message text. Maybe they will get tired of answering the same questions over and over and document the messages. -OR- Go read the restrictions of what can and cannot be changed with OBEYFILE in TCP/IP Planning and Customization. Some things cannot be changed, and must NOT b e in the file supplied to OBEYFILE. In particular, it cannot handle a full PROFILE TCPI P.
