Subject: SNA/MS Questions from AIW Attendees

Hello! This is an introductory note from the Generic Alert Code Point
Registry where you will be able to request new code points for Generic
Alerts as well as ask any simple Generic Alert questions you may have.

I am working to improve a process which will allow you to easily request
new code points. This should be available in the near future.

To request new code points (after I have set up the process) or for an
answer to simple questions, you should contact this registry using the
alert internet address (alias) which is "[email-masked]".
Also note the phone and fax numbers in the trailer of this note.

To better serve you, this address is capable of being administered by one
person or a team, whichever is necessary at any time.

Now, for the answers to the last two of your questions from the AIW,

1. Selecting which name NetView displays from the Hierarchy Resource List.

NetView presumes that the last name in the Hierarchy Name List (X'10')
subfield in the Hierarchy/Resource List (X'05') subvector in a Generic
Alert (X'0000') is the name of the resource causing the Alert. To prevent
this last name from being displayed on the Alerts dynamics screen, you
must set bit 1, Display resource name indicator, in the Flags byte (r+1)
of this last name to 1.

The general rule is that the last name in the list with this bit set to 0
is the name NetView displays, unless they are all set to 1, in which case
the last name is displayed as if it's bit had been set to 0.

Refer to page 9-333 in the -12 edition of the SNA/Formats manual for this
architecture.

The Resource type identifier of the last name in the Hierarchy Name List
(X'10') is always displayed. An '*' is displayed next to the Resource
type identifier whenever the last Resource name is not displayed.

2. A way of getting NetView to display longer (>8 char) resource names.

The HRL name length restriction is a problem that will not be easily
fixed in the seeable future, however, there is a limited method which
will allow the display of resource names longer than 8 characters.

By using Detailed Data Extended (X'85') subfield(s) in the Detailed
Data (X'98') subvector in the Generic Alert (X'0000') as shown below,
resource name(s) over 8 characters can be displayed on a NetView screen.
You can use ...

SV98
  ll85ii00A70011eeeeeeeeeeeeeeeeeeee...

         where ll-length, ii=psid index, ee=ebcdic characters

as  long as you have the latest NetView without the 44 character
restriction. The latest NetView overall limit is 253 bytes.

Where you have the back levels of NetView, you can follow the A7 with 00
data IDs and the appearance is of a continued name.

  ll85ii00A70011eeeeeeeeeeeeeeeeeeee...
  ll85ii00000011eeeeeeeeeeeeeeeeeeee...

        where ll-length<44, ii=psid index, ee=ebcdic characters.

Either will result in displaying something like the following on the
Alert DETAILS panel.

    QUALIFIERS:
      RESOURCE ccccccccccccccccccccccccccccccccccccccccccccc
      ccccccccccccccccccccccccccccccccccccccccccccc

Refer to page 9-172 for sf85 and page 9-128 for sv98 (-12 SNA Formats).
The ii (SF85 byte 2) is the same as the PSID Index (X'83') subfield.

Note, while sf82 can be used rather than sf85, sf85 is preferred.
