Sizing Log Streams for CICS Threshold and Exception Records

This sample table sizes log streams for CICS threshold and exception records:

RetPd Days	Avg Rec Length	Hourly Count	Total Byte Requirement	Max Dsns	4-KB Blocks	Cyls
7	250	250	10,500,000	10	256	2
14	250	100	8,400,000	14	146	1
14	250	300	25,200,000	14	439	3

Consider the following:

Hourly Count
This count equates to:
- The average number of CICS thresholds triggered
- The number of CICS exceptions that occur per hour
If the data from multiple CICS regions get logged to the log stream, then this value must be the combined total for those CICS regions.
The volume of this log stream should be low.
The large amount of data can be maintained.
