ADMINISTRATOR SECTION: CHAPTER 2 - CONFIGURING THE ER 3.0 SERVER

Since archive data contain no indexes, they occupy less space on the Server than live data—which include indexes and pages/objects. However, reports generated for periods of time with archive data take longer to process since indexes are not included for that data.

Expire - pertains to the action of dropping data from the Server when there is no room left on the hard drive for additional storage. When the hard drive reaches its maxi- mum data storage capacity, indexes from the oldest week of data stored on the Server are dropped, or “expired” from the Server. Thereafter, when more space is needed on the Server, the oldest week of non-indexed data “expires.”

Expiration Rules

The administrator of the Server specifies the number of weeks of data that will be stored on the Server, based on the storage capacity of the hard drive, and the number of hits on the Server. After inputting the percentage of live data to be stored, the Server translates that figure into the equivalent of weekly time periods for live and/or archive data storage.

When the Server reaches the maximum number of weeks allocated for live data storage, the oldest week of live data stored on the Server attains an archive data status. In attain- ing an archive data status, the index for that week of data is dropped from the database tables.

When the Server reaches its maximum number of weeks allocated for archive data storage, the oldest week of non- indexed data stored on the Server is automatically dropped (expired) from the database.

Once data expires, it cannot be recovered.
