Unity Solaris Kit:

  • New Machines

    The Recommended patchset on the Solaris 8 install machine now reflects the latest from Sun. Of note, this includes the patches that make Solaris 8 work correctly for this upcoming Daylight Savings Time change. This patchset has been tested by doing a generic server install, and everything appears to be working correctly, but there's always the possibility that something broke. New installations starting last week, should have this patch in place already.


  • Existing Machines

    For existing Solaris 8 boxes, the two necessary patches for the Daylight Savings Time change in:

    /afs/bp.ncsu.edu/system/solaris_addins/dstfix

    Anyone with install privileges should have access to that directory.

    There are a couple caveats to this patchset:
    • The patch 108993 is a "libc" patch and so it must be installed from single-user mode, and it requires an immediate reboot
    • It also modifies /etc/pam.conf. After the patch is installed, a "mv /etc/pam.conf.pre108993-64 /etc/pam.conf" needs to be performed

  • Steps to Apply Patches

    To apply these patches, copy the files 108993-65.zip and 109809-05.zip from

    /afs/bp.ncsu.edu/system/solaris_addins/dstfix

    to a directory local to the machine since these have to be applied in single user mode.
    Unzip the files and you will have two directories: 108993-65 and 109809-05.

    1. Shutdown the machine to single user mode:
      either "init 0" or "reboot -- -sw" or your other favorite method
    2. Mount any filesystems you need and change to your local directory of the patches
    3. patchadd 108993-65
    4. mv /etc/pam.conf.pre108993-6? /etc/pam.conf
    5. patchadd 109809
    6. reboot

    Your machine should now be patched for daylight savings time if you are Solaris 8.

    NOTE: These patches are NOT to be applied to Solaris 6 or 7 (it will result in a non-functional machine).
