Where are Control-M/Tape Repository Files Allocated?

Determine where each file in the Control-M/Tape repository is allocated. The Control-M/Tape repository consists primarily of the following files:

Table 2 Control-M/Tape Repository Files

File	Description
Media Database	All information about data sets and volumes managed by Control-M/Tape.
Stacking Database	Statistical information on each data set. Used for calculating the amount of space needed for storage of each data set.
Trace file	A record of all important activities in the Control-M/Tape environment. Used for recovery of the Media Database and for tracking.

The Media Database and the Stacking Database are each composed of two physical files:

Table 3 Media Database and the Stacking Database

File	Description
