Number of Records
Using Queue 0 as an example, each record consumes:
In this example, each record consumes 18 bytes. So if one queue was
configured, the maximum number of records that could be stored would
be 7281. The maximum number of records is calculated by:
Maximum Number of Records = Data Log File Size/Record Size
= 128K bytes/18 bytes
= (128)(1024)/18
= 7281 records
Example Queue 5
String Length of Record
The size of a record is limited so that the length of the maximum
formatted string does not exceed 80 characters. The following table can
be used to determine the formatted string length.
