2. Enter or select a custom directory and click OK.
3. Select Expert > TCM Expert Parameters.
The TCM Expert Parameters dialog box appears.
4. Accept the default Capacity History time period (six months) or specify a new one.
This field specifies the time range that is used in three situations:
• The time range that is checked for transaction cost consistency when Generate Expert is
executed
• The time range that is checked for transaction cost consistency when Update History with
Selected CSV Samples is executed
• The time range that is used when the Pick Best Sample option is selected
5. If you are logged on as an administrator or at a higher level, accept the default Cache Miss
Factor or enter a new one.
The Cache Miss Factor specifies the relative CPU cost to the disk process of a cache miss as
compared with a cache hit. The default settings assume that it takes twice as much CPU time
to get data off the disk than to get data from cache (memory). That is, a cache miss costs twice
as much as a cache hit. A TCM administrator or superuser can modify this factor.
