For queue 5, the formatted string length is 29 characters, as shown below:
= 8 + 1 + 6 + 1 + 6 + 1 + 6 = 29 characters
Number of Records
Using Queue 5 as an example, each record consumes:
Each record consumes 10 bytes. So if only one queue was configured, the
maximum number of records that could be stored would be 13107. The
maximum number of records is calculated by:
Maximum Number of Records = Data Log File Size/Record Size
= 128K bytes/10 bytes
= (128)(1024)/10
= 13107 records
