If your IBM CMOD Cache Filesystems are large (over 1 terbyte) then the default setting for the <code>arsmaint -c </code> will leave 20% - 200 gigabytes of empty cache. If you have multiple 1TB cache filesytems, and you only load 20GB per day, you could have a huge amount of wasted space in your caches. You can adjust this number with the <code>-m </code> and <code>-n </code> options for [[arsmaint]] to set new maximum and minimum caches sizes during cache expiration. | If your IBM CMOD Cache Filesystems are large (over 1 terbyte) then the default setting for the <code>arsmaint -c </code> will leave 20% - 200 gigabytes of empty cache.

The other ways to tune the cache filesystems are to analyse the patterns of retrievals of Application Group data, and change the cache retention to match actual end user usage, and to use data from your load and retrieval patterns to determine your optimal cache size.
