Changing configuration of SNAPlus2

[Bryan V Hardwick_1]

Has anybody experience of changing the configuration of SNAPlus2. I have a server that has had it's hostname changed and I would also like to reflect this in the SNA config. I am also going to need to change the ILU that the server is known by.

Any ideas would be nice.

Cheers,

Wow... haven't touched SNA in years... good to know there are people still using it. I'm a little fuzzy but I'm guessing that changing the name of an independant LU while fairly straightforward through the xsnapadmin GUI will need to be reflected at the other end of your connection (presumably an IBM mainframe/ AS400 or the like). You'll probably need to talk to the systems programmers who run the mainframe and get them to make changes to VTAM/NCP (the mainframe equivalent of snaplus2!). If you have applications at your end that initiate the connection to the mainframe then you are also going to have to track down where the ILU is configured in the application, as this is the reference an application uses to access remote SNA resources.

Before you make any changes take a backup of the file /etc/opt/sna/sna_node.cfg so you can go back to your old config if you screw up.

The good thing about SNA is, that as it is connection oriented you should know straight away if you have a problem.

Sorry I'm too fuzzy to remember much more than this... hope its at least slightly useful.

Thanks for the response. I have already engaged the MF people and they have defined a new ILU on this line.

So to change the ILU I presume I remove the old one and add the new one?

Do you know if all the SNA config is in this file? I also want to change the host name. The GUI says this Amex9 in the top right-hand corner, but the first entry in the Indipendant local LU's is Amex1 (the old hostname)?

I also have a change on another server which is the comms hardware address, I have found this in a file /etc/opt/sna/sna.ini, do you know if there is any configuration/re-compile that has to be run to make this work?

Cheers,
Bryan.

Hi Bryan

A change of hostname won't have any reflection on your sna configuration unless you have defined a cp alias within sna_node.cfg that you have called the servers hostname

[define_node]
cp_alias =
