Performing an offline update sysgen
Use the information given below when performing a offline update
sysgen.
When to use An offline update sysgen is normally performed for the following
purposes:
•
To add major new features to the existing operating system
•
To replace the existing version of the operating system with a
new version.
Note: When performing an offline (tape) sysgen, make sure the
system is offline.
No disk format required System disks are not formatted prior to an update sysgen, so user
files need not be backed up as long as there is sufficient room on the
disks to generate the new system.
Choosing a sysgen command
There are two types of sysgen commands. The following
informations describes each and when to use.
•
The SYSGEN command updates system files from a system
software tape (SST) or cartridge, and gives you the option of
making configuration changes, deleting the accounting file, and
recompiling the font files.
•
The AUTO command updates system files from either a SST or
a SSC. It enables you to recompile the font files. There is no
configuration update, and the account file is saved
automatically.
Note: If you invoke any one of these commands after a FORMAT
command, a full sysgen is performed.
Offline update sysgen procedure summary
The following steps are used to perform an update sysgen.
Step 1. Load the sysgen processor into main memory. If you are installing a
new version of the operating system, make sure to load the new
sysgen processor.
Step 2. Install the new OSS using either the SYSGEN or AUTO command.
Step 3. Apply patches.
Note: An update sysgen resets the patch history file.
