Defining the Recorder File BIM-EPIC System Datasets
2-22 BIM-EPIC Installation and System Guide
3. Use the following table to determine the number of CKD tracks or FBA blocks to allocate
for various Recorder sizes:
Device Number of Records
Type 1000 2000 5000 7500 10000 20000
3390 10 20 50 75 100 200
3380 10 20 50 75 100 200
3375 10 20 50 75 100 200
3350 24 48 120 180 240 480
3340 42 84 210 315 420 840
3330 34 68 170 255 340 680
9345-1 48 96 240 360 480 960
9345-2 72 144 360 540 720 1440
FBA 668 1336 3340 5010 6680 13360
Determine which disk volume will be used for the Recorder File. The Recorder File and DSN
Catalog should be placed on different physical devices.
For performance reasons, the Recorder File should be placed on a volume which does not
contain heavily accessed datasets such as POWER files.
The Recorder File must be a single extent dataset.
The Recorder File provides backup security for the DSN Catalog. If the DSN Catalog and
Recorder File are both located on the same device and that device is lost or damaged,
information vital to recovery of the DSN Catalog will be lost.
