Hello.
I am trying to install V8 with DRDA.

I have created a VTAM LU that should handle the requirements. DB2 starts fine. When I start DDF, I get a Gethostbyaddr RC2 failure. When DDF starts, it specifies LOCATION (which I took to be the HOSTNAME used by TCP/IP) and the DOMAIN (which I have no idea where to specify to DB2 or DDF, I went all the way through the SDSNINST clist again and saw nothing about DOMAIN)

Anybody who knows more about this, I could really use the help!

djf,

DB2 uses the LINKNAME column of the SYSIBM.LOCATIONS catalog table to determine which protocol to use. To receive VTAM requests, you must select an LUNAME in installation panel DSNTIPR. To receive TCP/IP requests, you must select a DRDA port and a resynchronization port in installation panel DSNTIP5. TCP/IP uses the server

Thanks.
But I've read most of it, and am still confused. In fact, while I eventually want DRDA to work, my real problem is the install of QMF, which dies in the QMFBLNI job trying to open the port. For what, I have not a single clew.

I have a VTAM LUNAME defined, I have assembled the modent tables, and a display of the LU shows he is talking to UDB8DIST.

I have also assigned the 446 and 5020 TCPIP ports to DRDA.

I have also RACF assigned a userid to UDB8DIST with superuser authority.

But I am still getting these damnable GETHOSTBYADDR failed RC2 messages, which leads me to think that something in the DB2/DRDA definitions isn't matching something in the TCPIP definitions.

I hate TCPIP and DB2 ain't very far behind...

OK. I've pretty much decided this is not a DB2 issue. When I slap together a REXX exec to do socket calls, GETHOSTBYADDR hangs.

So I need to look at my TCPIP resolver stuff.

(can I still blame it on DB2??? Didn't think so...)

Yay! I changed resolver lookup from DNS to local and now get:

DSNL519I -UDB8 DSNLILNR TCP/IP SERVICES NOW AVAILABLE FOR DOMAIN MYZOS PORT 446

dang I'm good...
Very Happy

Takes us "beginners" a while to get warmed up, eh?
