Resolution

The scripts which run to update the server did not complete. See the Additional Information section below.

Follow these steps:
  • In a putty session or at the server terminal, cd to the scripts directory:
    • cd /var/adm/update-script
  • Execute each script in the following order
    • Wait for each script to complete before executing the next script
      • ./filr-db-4.2.0-412.1-update-database.sh
      • ./vabase-build-keys-15.0.3-4.1-import.sh
      • ./web-filr-config-4.2.0-290.1-add-crontab.sh
      • ./filr-webapps-4.2.0-269.1-update-server-xml.sh
      • ./web-filr-4.2.0-290.1-restart-9443-services.sh
      • ./novell-filr-famtd-4.0.0-35.1-famtd-changes.sh

Cause

The Online update process failed to run the required update scripts.
