Goal

A common .. but hopefully not regular ... message that can be seen in the alert log is: 

   " kccrsz: denied expansion of controlfile section ## by ## record(s) the number of records is already at maximum value (65535)"

Examples:

kccrsz: denied expansion of controlfile section 9 by 65535 record(s) the number of records is already at maximum value (65535)
kccrsz: denied expansion of controlfile section 11 by 65535 record(s) the number of records is already at maximum value (65535)
kccrsz: denied expansion of controlfile section 19 by 65535 record(s) the number of records is already at maximum value (65535)

This message is not very descriptive and as such ... it is hard to understand what has happened

This note will attempt to clear up this confusion
