1.3 Preliminary Tasks for Upgrade Installations

1.3.1 Save Tailor File

If you have made any changes to your PMDF tailor file (/etc/pmdf_tailor), you must save this file before you upgrade because it will be overwritten by the installation.

After upgrading, you should check the new pmdf_tailor file and merge in any changes that you made to your version of the file.

1.3.2 Change PMDF User Account Name

If you are upgrading from PMDF V5.0, change the PMDF user account name before you start the upgrade. If you are upgrading from PMDF V5.1 or later, skip the this section and go to the installation procedures.

PMDF V5.0 used pmdf_user to specify a PMDF user account (an unprivileged account used for performing some specialized tasks). As of PMDF V5.1 the name of the PMDF user account is pmdfuser. This PMDF user account name is relevant for sites using PMDF sequence number files.

Note

The old pmdf_user was problematic on Tru64 UNIX systems, as it is greater than eight characters in length.
So, if you have an old PMDF user account with the old name pmdf_user, change it to use the new name, pmdfuser. However, if you do not want to change the account name at this time, you can use the following command to set the PMDF_USER_USERNAME option in the PMDF tailor file (/etc/pmdf_tailor) to point to the old PMDF user account name:


PMDF_USER_USERNAME=pmdf_user 
You will need to reimplement this change (or actually change the account name) each time you upgrade PMDF, since your PMDF tailor file is overwritten every time you upgrade.
