4.3 Configuring the XEDIT profile

Logon to MAINT (if not logged on already).

The XEDIT command looks for the file XEDIT PROFILE configuration file when it is invoked.

Many z/VM user IDs do not have such a personal or shared system file, so all XEDIT default

values are in effect. The MAINT 191 (A) disk has a PROFILE XEDIT so when you are editing files

on MAINT, the values in this profile are usually in effect.

If you have never used XEDIT before, refer to , “XEDIT quick reference sheet” on page 212,

for more information about this topic. The z/VM 5.4 PDF library is available on the Web at:

http://www-03.ibm.com/systems/z/os/zos/bkserv/zvmpdf/#zvm54

Search for the XEDIT User’s Guide and Command Reference. Also there is an old manual

available online:

http://ukcc.uky.edu/ukccinfo/391/xeditref.html

One default setting that can be dangerous, especially if you use F12 to retrieve commands, is

that PF12 is set to the FILE subcommand. Sometimes you may not want to save your changes

with the stroke of one key. We recommend that you set PF12 to the ? subcommand, which

has the effect of a retrieve key:

==> copy profile xedit a profile xediorig a (oldd

==> x profile xedit a

Before:

SET PF12 FILE

After:

SET PF12 ?

Save your changes with the FILE subcommand.

HMC Integrated 3270 Console or 3270 emulator? At this point, z/VM should be

accessible over the network. You can continue working at the HMC, or you can access your

new system using a 3270 emulator.

If you want to switch to 3270 emulator, first LOGOFF from MAINT or issue DISConnect on the

Integrated 3270 Console. Note the following points:

򐂰 If you log off, the session is ended; it is analogous to shutting and powering down a PC.

򐂰 If you disconnect, your session remains where it is and is resumed when you log back

on; it is analogous to turning off a PC monitor.

In general, you should LOGOFF from system administration user IDs such as MAINT.

However, you should always DISCONNECT from z/VM service machines such as TCPIP and

user IDs running Linux, because logging off from them will terminate the service or crash

Linux.
