Step 3.2 – Control-O data sets

Table 98 Control‑O data set parameters

Parameter

Description

STREC#

Maximum number of message IDs that can be accumulated. This parameter determines the size of the Control‑O Statistics file. BMC recommends a specification of 10,000 or a higher figure.

  • Default: 10,000.

This parameter is ignored if the STATO parameter is set to N.

ALREC#

Maximum number of messages that can be stored in the Automation log. The Automation log is a wraparound file. When it becomes full, Control‑O overwrites the oldest messages. Calculate this parameter according to the number of messages per day, and the number of days you want the messages to be kept in the Automation log. Each message record is 364 bytes long. For example, if a site has 100,000 messages a day, the Automation log requires 61 cylinders of 3390 disk space to hold the contents of one day of processing.
