Steps to perform an online update sysgen (continued)
Step
Action
7.
To discard the changes you just
(cont.)
made and continue sysgen, enter Y.
To save the changes you just made
and continue sysgen, enter N.
8.
Enter Y and <ENTER>.
9.
For an online sysgen, Enter H (host)
and press <ENTER>.
Request the host operator to vary the
printing system online.
Notes:
You must use a host utility program
to advance the SST to the next-to-last
file. This file, which consists of 128-byte
and 8192-byte fixed-format blocks,
must be deblocked to 128-block
records (without adding page
numbering or reformatting the data)
before transmission to the LPS. Refer
to the appendix for an example of a
typical host utility program for file
transmission.
If you have a user-created SST for
an online system, you do not need
to advance the tape to transfer the
first file (which contains the new
sysgen processor). Simply mount
the tape and initiate the file transfer
process at the host.
Enter N and <ENTER>.
10.
Request the host operator to vary
the printing system offline, then
enter C. (You need not press
<ENTER>.)
