Purge Entries From the Classification Cache

If classification cache grows too large, cache performance or stability may be adversely affected. If this situation occurs, we recommend that you first modify the HighWatermarkPercent and LowWatermarkPercent settings for the Cache Maintenance Service. However, if problems persist you can use CacheUtil to purge cache entries based on their age.

To purge cache entries

Go to the CCS \bin folder and run the following command:

CacheUtil -purge <period>

Where <period> can be:

-max-age-hours <n>

This argument specifies the maximum age of cache entries in hours. CacheUtil purges all cache entries older than this maximum age.

-max-age-days <n>

This argument specifies the maximum age of cache entries in days.

-max-age-weeks <n>

This argument specifies the maximum age of cache entries in weeks.

-count <n>

This argument specifies how many cache entries to purge, starting with the oldest entries.

-all

This argument purges all cache entries.

Examples

• This command purges all cache entries more than six hours old:

  CacheUtil -purge -max-age-hours 6
  

• This command purges all cache entries more than two days old:

  CacheUtil -purge -max-age-days 2
  

• This command purges all cache entries more than four weeks old:

  CacheUtil -purge -max-age-weeks 4
  

• This command purges the oldest 100 cache entries:

  CacheUtil -purge -count 100
