Verify a successful upgrade

  • Load the applications and verify the basic operations firsts as login, load process and data displayed. 
  • Review the specific application log for errors (opEvents.log, opCharts.log, etc)
  • The installer saves a log of all actions taken, files copied etc. in the installation directory as install.log, ie. normally it'll be in /usr/local/omk/install.log. Subsequent upgrades or installations of other Opmantek products will add to that logfile, so you may very well want to remove or clear the install.log file before upgrading or adding extra software.

    Unless this is the very first installation of an Opmantek product on this system, the installer will offer taking a backup of all affected files before the installation commences. This backup will be saved in the root user's home directory as omk-backup-YYYY-MM-DD.tgz. The backup includes:

    • all the directories that the installer will later copy files to,
    • the conf directory,
    • the old software manifest,
    • and the old install.log.

Restoring from backup

How to restore from a failed upgrade


This is the process to use if you need to roll back from the installer using this backup:

# send email to with advance warning before restoring from backup


service opeventsd stop
service opconfigd stop
service opchartsd stop
service omkd stop
# confirm that the required Opmantek services have stopped
/usr/local/omk/bin/ status
cd ~
mkdir temp
tar -xvf omk-backup-YYYY-MM-DD.tgz -C ~/temp
unalias cp
cp -R ~/temp/* /usr/local/omk
# at this point this error may occur:
#   cp: cannot create regular file '/usr/local/omk/bin/opchartsd.exe': Text file busy
#   cp: cannot create regular file '/usr/local/omk/bin/opflowd.exe': Text file busy
# if this happens: do
#       mv /usr/local/omk/bin/opchartsd.exe /usr/local/omk/bin/opchartsd.exe.old
#       mv /usr/local/omk/bin/opflowd.exe /usr/local/omk/bin/opflowd.exe.old
# and then: do
# cp -R ~/temp/* /usr/local/omk

service opeventsd start
service opconfigd start
service opchartsd start
service omkd start
# confirm that the Opmantek services are all running
/usr/local/omk/bin/ status

You also need to run the installer for each previously application that was installed in order to downgrade properly and have the initd and systemd services restored too.

 service opeventsd start
service opconfigd start
service opchartsd start
service omkd start
