HWT004 How to increase the number of TSO terminals

The original MVS Turnkey system by Volker Bandke has only three TSO sessions active. The hercules.conf file must be modified
to contain the new addresses of the terminals requiring you to restart hercules. The member LCLMAJ00 in SYS1.VTAMLST controls
the availability of terminals. The first section of this file is shown below.

000001 LCLMAJ00 LBUILD SUBAREA=2
000002 CUU0C0   LOCAL TERM=3277,CUADDR=0C0,ISTATUS=ACTIVE,                    +
000003                LOGTAB=BSPLIN01,LOGAPPL=NETSOL,                         +
000004                FEATUR2=(MODEL2,PFK)
000005 CUU0C1   LOCAL TERM=3277,CUADDR=0C1,ISTATUS=ACTIVE,                    +
000006                LOGTAB=BSPLIN01,LOGAPPL=NETSOL,                         +
000007                FEATUR2=(MODEL2,PFK)
000008 CUU0C2   LOCAL TERM=3277,CUADDR=0C2,ISTATUS=ACTIVE,                    +
000009                LOGTAB=BSPLIN01,LOGAPPL=NETSOL,                         +
000010                FEATUR2=(MODEL2,PFK)
000011 CUU0C3   LOCAL TERM=3277,CUADDR=0C3,ISTATUS=INACTIVE,                  +
000012                LOGTAB=BSPLIN01,LOGAPPL=NETSOL,                         +
000013                FEATUR2=(MODEL2,PFK)

When you want to add terminal addresses make sure that the address on the left in the first term entry matches the CUADDR=
parameter in the center. Also the term's status is indicated in the ISTATUS parameter. If it is set to "INACTIVE" manual
action at the console will be required to bring the terminal online to TSO.  When making changes to this file note
the continuation + sign in column 72, be sure it's still in it's proper location when finished. Addresses typically go from
0C0-0C7, 1C0-1C7, 2C0-2C7, etc.

When finished saving the member you must follow this procedure to activate the changes:

 Shutdown TSO -    p tso

 Stop VTAM -       z net,quick

 Rebuild VTAMOBJ - s resetobj

 Start VTAM -      s net     

 Start TSO         s tso

Your new sessions should be ready to use.

Should you want more terminals than the sysgen allows for the MVS system must be re-gened(beyond the scope of this article).
