Re: LU0, SNA, TCPIP issue
Radoslaw, LU0 is a dependent LU so it must have a PU2 of some sort, PU2.0 or PU2.1, to support it. PU 2.1 is more strictly defined more strictly as a 2.1 Node or Control Point (CP). This means you will need an SNA stack somewhere in the configuration. If the LU0 is in Windows, assumed from your current use of HIS, I reckon that means you will need an SNA stack in Windows if you are to keep the LU0 function unchanged. There are configurations with a 2.1 Node and DLUR that give options for splitting the SNA functions, but I can't think of any that avoid have an SNA stack in Windows. For instance, Cisco SNASw has a CP (2.1 Node) and DLUR in a router supporting a downstream PU2.0 together with its dependent LUs. However, this still needs PU2.0 support in Windows.

It also means to stay with LU0 (application "understand" LU0). BTW:The client application is NOT 3270 emulator, it is "our own" GUI based client, which talks to the windows server application which in turn talks to mainframe (via HIS). I think it would be enough to change last layer of the application which talks to HIS and simply set up telnet server on host side. -- Radoslaw Skorupka Lodz, Poland This e-mail and any attachments are confidential and intended solely for the addressee and may also be privileged or exempt from disclosure under applicable law.

Re: Using unique HOSTSA (running VTAM as pure EN/NN) = 'Better Manageability'?
> If you omit HOSTSA you'll get SACONNS=NO. This point doesn't jump out at me from Table 70, "Node type functional summary" and yet I believe you must be right - and I'll have to revise my just created diagrams. In principle the default value for the SACONNS start option is YES - just take a look as the description! - but, in order to reproduce the rules as they applied before the SACONNS start option appeared, not specifying HOSTSA and specifying NODETYPE *must* eliminate external subarea, in other words, SACONNS=NO must be assumed. Time for yet another "reader's comment form"! Just for completeness - as the original question was about a VTAM running EE we know that NODETYPE was coded. What I said would not be true on a non-APPN VTAM without NODETYPE. Then, as Chris's table showed, you'd have a subarea-only VTAN with subarea number 1.

Re: Using unique HOSTSA (running VTAM as pure EN/NN) = 'Better Manageability'?
"For better manageability we recommend defining or keeping a unique subarea number using HOSTSA" There's no benefit in unique APPN-only HOSTSAs that I know except this odd one. Some systems we've inherited have automation that examines the subarea number to decide on actions to take. We've left HOSTSA and coded SACONNS=NO. If you look at a network management tool like NetView NLDM or run VTAM traces of application FID4s you'll see subarea number 1 under the wraps. Seeing subarea 1 is a good reminder you've got rid of the subarea functions from VTAM. "and running VTAM as a pure EN/NN by coding SACONNS=NO." Running as a straight APPN node NN or EN, rather than as an ICN or MDH, is the way to go. If you've inherited VTAMs with subarea and the complex subarea PATH statements, VRs, ERs and the like it is time to simplify to APPN only. If you omit HOSTSA you'll get SACONNS=NO.

Group, I have been reviewing the Enterprise Extender Implementation guide (SG24-7359) in Chapter 3 it talks about HOSTSA and SACONNS. It says "For better manageability we recommend defining or keeping a unique subarea number using HOSTSA, and running VTAM as a pure EN/NN by coding SACONNS=NO.". The default HOSTSA is 1 and I see it on a few End Nodes. I did see under ENHADDR is says "Even with VTAM running as a pure APPN node, internally all resources are represented using a FID4 subarea address format.". So internally it looks like it references HOSTSA. I have been trying to evaluate EE performance and have been doing a lot of different displays. I don't recall seeing subarea 1 when doing these displays. Q). What "better manageability" would the authors be talking about?

Re: restricting how I do things so that others understand?
Sounds OK, but does your site have well-practiced backup, restore and DR processes for Unix files?

I'm working on a project which involves "converting" a lot of VSAM files. So far, I've restricted myself to using PDSes and REXX. Everybody in my group (mainframe sysprogs) understands these. But, for my own convenience, I'd like to use UNIX files. Why? Because I can create really long file names, such as: export-jcl., import-jcl., define-jcl., and so forth. But nobody else in my group really "digs" UNIX stuff and none of them, other than myself, actually likes it. So, should I restrict myself to only using generally understandable stuff. Or, since this project is not production (basically do the conversion then ignore it), should I just do it the way that is easiest for me? The problem with this is that there are a large number of files to convert and it will take quite a while. So using UNIX basically means it is my baby entirely. -- John McKown Maranatha! <>< -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html This e-mail and any attachments are confidential and intended solely for the addressee and may also be privileged or exempt from disclosure under applicable law.
