Managing file purging
In Volumes—Properties—Advanced—Archiving and Purging, shown in Figure 12‑2, you can specify expiration times for Encyclopedia volume items.
Figure 12‑2 Specifying Encyclopedia volume item expiration times
Table 12‑2 describes the parameters that appear on System Volumes—Properties—Advanced—Archiving and Purging. Purging notices reduces the size of the Encyclopedia volume and contributes to better performance.

Parameter
Description
Expiration time of failed jobs
Length of time before iHub can delete a job completion notice for a failed job from Jobs-Completed. iHub purges the notice during the scheduled completion notice purge time if no completion notice for the failed job exists on a volume channel, and the age of the notice exceeds the value of this parameter. The lower the value of this parameter, the better iHub performs. If an administrator specifies 0 for this parameter, iHub uses the default value for the volume.
Expiration time of successful jobs
Length of time before iHub can delete a job completion notice for a successful job from Jobs-Completed. iHub purges the notice during the scheduled completion notice purge time if no completion notice for the successful job exists on a volume channel, and the age of the notice exceeds the value of this parameter. The lower the value of this parameter, the better iHub performs. If an administrator specifies 0 for this parameter, iHub uses the default value for the volume.
Default expiration time of success notices
The default value for the volume specifying the length of time before iHub can delete a job completion notice for a successful job from a user’s personal channel. This is the same property as Purge success notices after n days n hours, in Management Console, Volume—Properties—Archiving and Purging. Setting this property in one console sets the property in the other console. iHub does not delete the notice if the value for this parameter is 0, the default value.
Default expiration time of failure notices
The default value for the volume specifying the length of time before iHub can delete a job completion notice for a failed job from a user's personal channel. This is the same property as Purge failure notices after n days n hours, in Management Console, Volume—Properties—Archiving and Purging. Setting this property in one console sets the property in the other console. iHub does not delete the notice if the value for this parameter is 0, the default value.
