Object Configuration Client: The Understanding 56
3-9 Maintenance
An object is monitored for various policies and normally the object is always configured on the host system.
However, in a transient situation like the daily transaction files, it is not possible to know what the object state will
be from one day to the other. However, the policy to manage the object remains the same. For instance, a file
that is transferred or created on a daily basis for transaction processing will get generated daily, and it might not
be possible to configure the static name of the file object. However, once the file is generated, it is important that
the file does not get full or corrupted, as defined by the policy. The Auto Maintenance facility automatically
rediscovers new objects and applies the policy defined by the user. This can be done on a daily or an hourly
basis depending upon the requirement of the user. The smallest rediscovery time-period is 30 minutes.
Let’s take File Transfer as an example. Your application may receive files on a regular basis, several times a day.
You want to make sure those files are configured in such a way that they never fill up. You can create a
FILESYS/PERCENT FULL threshold using a template that describes where the files will exist. By using Maintenance,
you will be able to define the frequency of auto-maintenance. At that interval, OCC will search for new files that
are within that template and apply the PERCENT FULL threshold. If the files are transient and always have unique
names, you would use the Rebuild option to prevent the system from monitoring files that will never exist again.
By using this feature, you eliminate the need to manually tell OCC to rediscover new objects.
The Auto mai
ntenance feature is not available for the EMS subsystem.
Clicking the Advanced button in the Threshold dialog box displays the Advanced Options dialog box. The
Maintenance tab page of the Advanced Options dialog box can be used to schedule maintenance and
reconfigure the environment.

The Auto Maintenance list box provides the following options:
• None
• Rebuild
• Update (add only)
You can remove all the objects and rebuild the environment or update the existing environment using the Auto
Maintenance list box. Select the None option in Auto Maintenance to disable maintenance.
