Simple VTAM-Question?

2008-10-15 Thread Michael Knigge

All,

I've modified my VTAM Logon Screen and now want to activate it. Is 
this possible without an IPL? I guess I have to do a F LLA,REFRESH and 
then to restart the TN3270-Server. But what do I have to do for the 
real 3270-Terminals? Restart VTAM? How?



Thank you - guess it is a simple question for VTAM-Guys but I'm pretty 
new in this area



Bye,
Michael

For your TN3270 server you don't need to cycle the server, just refresh 
the profile.  Any new connections will pick up the new USS table.
  V TCPIP,TN3270,O,PROFILE.DATA.SET

For VTAM, use the following
   F NET,TABLE,OPTION=LOAD,NEWTAB=TABNAME

Look in the manual of operator commands under modify table (usstab).

Look up the MODIFY NET,TABLE command in the SNA Operation.  I think it 
is something like:


 F NET,TABLE,NEWTAB=tablename,OLDTAB=tablename

but it has been a long time since I had to use it.

I think you need the MODIFY TABLE command. Something like

F net,TABLE,OPTION=LOAD,NEWTAB=new_name

I am assuming you have revised the table so that it has the same name as it 
did previously.

Note that, as always for a MODIFY command, you need to use the name of 
the started task procedure, in this case the VTAM started task procedure 
which not all installations call NET.

Here are a couple of extracts from the MODIFY TABLE command text in the 
SNA Operations manual:

quote

Load a table to replace an existing table (other than a filter table):

MODIFY procname,TABLE,OPTION=LOAD,NEWTAB=new_table_name
(,OLDTAB=old_table_name)

/quote

quote

- F TABLE,OPT=LOAD

Allows you to replace old_table_name, which is in use, with new_table_name, 
which is currently not in use, or to reload a table that is in use. All 
resources 
currently associated with the old table are re-associated with the new table.

Note: If old_table_name is the current value of the DYNMODTB start option, 
the value of the DYNMODTB start option is changed to new_table_name.

If OLDTAB is omitted, it is assumed to be the same as NEWTAB.

/quote
 
You need to refresh the library lookaside (LLA) address space for modules 
other than modules from partitioned data sets in the VTAMLIB concatenation. 
The MODIFY command to which I pointed you above suffices.

As far as the Unformatted System Services (USS - used correctly, of course!) 
module used by the TN3270 address space is concerned, I'm afraid I can't find 
any particular description of how that can be replaced. I suspect that you 
need to issue a VARY TCPIP,tn3270proc,OBEYFILE command against the 
TN3270 PROFILE - at least the BEGINVTAM/ENDVTAM block - in order to have 
the TN3270 server refresh a load module referenced by the USSTCP 
parameter. I hope someone who knows for sure can confirm or correct this 
guess.

Well, welcome to a path to becoming a VTAM specialist. There are fewer and 
fewer these days.
