The following scenarios describe the configurations for capturing changed data when you enable CDC:
Do not set time stamp and disable reset CDC.
The
captures all the changes that occurred in the parent DN until the current time and updates the CDC file with the latest uSNchanged value.
When you next capture data changes from the LDAP directory server, the
reads the uSNchanged value stored in the CDC file. The
captures all the changes from the specified uSNchanged value in the file until the current time and updates the CDC file with the latest uSNchanged value.
Do not set time stamp and enable reset CDC.
The
captures all the changes that occurred in the parent DN until the current time and updates the CDC file with the latest uSNchanged value.
In a subsequent capture, the
ignores the uSNchanged value in the CDC file. The
captures all the changes that occurred in the parent DN until the current time and updates the CDC file with the latest uSNchanged value.
Set time stamp and disable reset CDC.
The
captures all the changes that occurred during the specified CDC start time and end time. The
then updates the CDC file with the latest uSNchanged value.
In a subsequent run, the
reads the uSNchanged value in the CDC file and captures all the changes from the specified uSNchanged value in the file until the specified CDC end time. The
then updates the CDC file with the latest uSNchanged value.
Do not set time stamp and enable reset CDC.
The
captures all the changes that occurred during the time period that you specified in the CDC start and end time. The
then updates the CDC file with the latest uSNchanged value.
In a subsequent run, the
ignores the uSNchanged value in the CDC file and captures all the changes that occurred during the time period that you specified in CDC start and end time. The
then updates the CDC file with the latest uSNchanged value.
