3-5-3 Recovery
One of the most important features of OVNM OCC is Recovery, which triggers automated actions in case of a
violation. You can define the recovery actions to be taken for different violation conditions. This feature is
disabled by default and has to be enabled manually. Recovery can be activated or inactivated at the
configuration and the object level using OCC.
• Threshold Level Recovery
To initiate recovery at the configuration level you can use the Activate Config Recovery and Inactivate
Config Recovery options in the Recovery menu. These two options can also be accessed using the Activate
Configuration Recovery and Inactivate Configuration Recovery icons on the Monitoring toolbar.
• Object Level Recovery
To activate or inactivate recovery at the object level you can use the Activate Object Recovery and
Inactivate Object Recovery options in the Recovery menu. These options are also available as the Activate
Object Recovery and Inactivate Object Recovery icons on the Monitoring toolbar.
Recovery can be enabled manually using the Action tab page in the Actions dialog box.

You can select the actions to be executed in case of a threshold violation using the first Command box. The
default value is None, which indicates that no recovery action will be triggered. Selecting the User defined
command option enables a second Command box, where you can enter the command to be executed. You can
specify any command that can be executed from a TACL prompt, like TACL command, TACL macro or Command
Line Utility/Program; in the User-defined command option. For more details please refer to Appendix N: Log
Success/Failure of User Defined Command for Recovery in the OVNM User and installation Guide. To use
substitution parameters in your command, click the Parameter list link.
There are also many thresholds that have pre-canned recoveries in the drop down list. Not every threshold has
these, but if they do, you should think about using these instead of writing your own recovery.
A generic ‘recovery’ option for all thresholds is “turn monitoring off/on for group/subgroup”. This is typically
used with EMS thresholds to automate the function of turning monitoring off or on for a set of objects. Using this
feature, you can group a variety of objects into the same group/subgroup and then create an EMS threshold for
a specific event that would use the Turn monitoring off for group/subgroup. When the EMS event is generated,
OVNM will consume it and automatically turn monitoring off for all objects that have the same value for group
and subgroup that was specified in the recovery. The same mechanism can be used to turn monitoring back on.
This is quite useful when you have a planned outage and do not want to send alerts or perform recoveries for
objects you know are going to be down. Another option instead of using EMS thresholds is to use the
ZTALTMON Tacl utility. This is described in more detail in the OVNM User Guide, in Appendix C: OVNM
Utilities.
You can schedule recovery 24 hours, seven days a week using the 24x7 option button in the Schedule section.
Define a customized schedule using the User Defined option button, which enables the Schedule button. Clicking
