Updating Linux

When you update Linux automatically by means of up2date, apt-get, SWUP, yum (http://linux.duke.edu/projects/yum/) or other RPM updaters, you must beforehand exclude some packages installed with Parallels H-Sphere from the update list:

• rh-postgres, postgresql, postgresql-server, postgresql-libs on CP and user postgresql boxes
• apache and apache-related packages on Parallels H-Sphere CP, WEB and MAIL boxes
• proftpd, frontpage and related packages on Parallels H-Sphere WEB boxes
• qmail, vpopmail, ezmlm, sqwebmail and related packages on Parallels H-Sphere MAIL boxes
• bind and related packages on Parallels H-Sphere DNS boxes
• XFree86 or xorg-x11 packages on CP. XFree86-deprecated-libs (or xorg-x11-deprecated-libs) with dependences should be installed. This is critical particularly for Parallels SiteStudio.
• MySQL-server on Parallels H-Sphere MAIL and MySQL boxes

Please note that these packages are also to be removed while preparing servers to Parallels H-Sphere installation.

If you have accidentally upgraded your RedHat without excluding these packages, you need to downgrade PostgreSQL.
