Defining the Recorder File
The Recorder File can be shared among BIM-EPIC systems. However, it cannot be shared
with CA-EPIC for CMS systems.
Estimate the size of the Recorder File.
1. Determine the number of records to be logged each day. One record is logged for
• each time a job starts or ends
• each time a program starts or ends
• each time an extent or reel of a cataloged dataset is opened or closed
•
each time the DSN Catalog is updated using Online Manager, TSIDMNT, or TSIDUTL
2. Use one of the following formulas to determine the amount of space to allocate:
For CKD tracks
R+4
4*B
For FBA blocks
R + 4
2
where R equals the estimated number of records to log each day.
B equals the number of blocks per track.
Use the following table to determine the value of B.
Device Type Number of Blocks
Per Track

3375 17
3350 7
3340 4
