Timestamps allow you to view the performance of the database send, receive, and apply processes for a data group to identify potential problem areas, such as a slow send process, inadequate communications capacity, or excessive overhead on the target system. Although they can assist you in identifying problem areas, timestamps are not intended as an accurate means of calculating the performance of MIMIX.
A timestamp is a single record that is passed between all replication processes. The timestamp originates on the source system as a journal entry, is sent to the target system, and then processed by the associated apply session. The timestamp record is updated with the date and time at each of the following areas during the replication process:
Created - Date and time the journal entry is created
Sent - Date and time when the journal entry is sent to the target system
Received - Date and time when the journal entry is received
Applied - Date and time when the journal entry is applied
After all four timestamps have been added, the journal entry is converted and placed into a file for viewing or printing. You can view timestamps only from the management system. The system manager must be active to return the timestamps to the management system.
