Thanks Chris for the explanation. I know that cdrscs can either be dynamically created or explicitly defined but do not know anything about APPN.
We have an ISC Link between 2 cics regions on 2 different lpars which pass thru a security product running on a 3rd lpar and I am still trying to figure out how to get them to work correctly when one side goes down and comes back up. The links seem to work fine during the day when we are here but somehow manage to misbehave on weekends and holidays when no one is around to fix them. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Chris Mason Sent: Thursday, December 03, 2009 9:59 AM To: IBM-MAIN@bama.ua.edu Subject: Re: VTAM - CICS definitions Eileen >The network has to be able to find the remote CICS APPLIDs on each lpar so probably cdrsc definitions are needed on both sides. This is LEN-talk[1]! You been spending too much time around the Microsoft SNA products maybe! APPN has those handy CP LU to CP LU sessions which are there - among other things/functions - to provide a distributed directory - whatever the configuration. Thus VTAM A can find out all it will ever need to know about the LUs defined within VTAM B and vice versa. Actually, in one sense, you are quite correct, CDRSC definitions *are* needed on both sides - but they are created dynamically by VTAM.
