Upgrading with Data Files in Place

WARNING

Beginning with release 7.4, the frame size changed from 2 KB to 4 KB. You must perform a file-save before installing D3 because you need to do a full restore and cannot upgrade with data files in place if you are upgrading from a system prior to release 7.4. See Upgrading with a File-Save Tape.

This section details upgrading from a D3 Linux system without performing a full file restore. The upgrade updates the Monitor, ABS, and data files of the dm account and the master dictionaries of all other accounts.

NOTE	Upgrading with data files in place is only supported when upgrading from D3 9.0 to 9.2. You cannot upgrade with data files in place to D3 9.2 from a D3 7.4.2 or 7.5.1 release.

Cautions

Before upgrading with data files in place, consider these cautions:

The ABS size is checked automatically by the pre-upgrade program. Do not follow this procedure if the pre-upgrade program warns that the ABS size of the new release is greater than the ABS size of the release that is being upgraded. Instead, go to Upgrading with a File-Save Tape. The pre-upgrade program also checks the existing version and frame size.
Since this is an upgrade, changing the number of ports or disk statements will force the system to require an upgrade using a file-save tape; upgrading with the files in place will not be permitted. Though the options are available, no changes should be made to the configuration parameters.
As part of the upgrade, customizations to the dm account may be lost. For example, the user-coldstart macro in the dm account is overwritten. Make a backup of the customizations to the dm account.
This upgrade procedure transfers spooler hold files to a data file, then shuts down the system for the upgrade. Spooler print jobs which are not hold files are lost.

To upgrade, execute these instructions:

Perform a file-save.

Ensure that there is at least one complete file-save (preferably two) of the system prior to starting the upgrade, and verify the save tape with the t-verify command.
A file-save tape does not back up spooler hold files. To back up the spooler hold files, use sp-edit (cv to turn them into items in a data file which can be saved to the file-save tape.

NOTE

The default statement to boot D3 is d3 -0. Although the ap command is currently supported (the pick command is not supported), replace the ap and pick commands with the d3 command, as future releases of D3 may not support ap. If the commands pick -{port} or ap -{port} are in the inittab file, change them to the new syntax.
