```
    Exposes the oldest(smallest) SCN in the Transactional Buffer
    
    Returns:
    
    oldest SCN
  - getCommittedScn
```
Long getCommittedScn()
```
    It shows last committed SCN
    
    Returns:
    
    committed SCN
  - getLagFromSource
```
long getLagFromSource()
```
    This is to get the lag between latest captured change timestamp in REDO LOG and time of it's placement in the buffer
    
    Returns:
    
    lag in milliseconds
  - getMaxLagFromSource
```
long getMaxLagFromSource()
```
    This is to get max value of the time difference between logging of source DB records into redo log and capturing it by Log Miner
