Message identifier format
Each message that is generated by CDC Replication has a unique identifier. All message identifiers for CDC Replication are at least eight characters in length and adhere to the following format:
CHC<message number><severity indicator>(<address space id>)
For all messages, the first three characters in the message identifier are CHC. This allows you to identify messages that are generated by CDC Replication.
The message number (<message number>) component is four characters in length. It is used to uniquely identify each message that is generated by CDC Replication.
The severity indicator (<severity indicator>) is a single letter that conveys the severity level of the messages. Table 1 identifies the severity indicators that are used. They are presented in increasing order of severity.
