- Method Detail
  - getCurrentScn
```
Long getCurrentScn()
```
    Exposes current SCN in the database. This is very efficient query and will not affect overall performance
    
    Returns:
    
    current SCN
  - getCurrentRedoLogFileName
```
String[] getCurrentRedoLogFileName()
```
    Exposes current redo log file. This is very efficient query and will not affect overall performance
    
    Returns:
    
    full path or NULL if an exception occurs.
  - getRedoLogStatus
```
String[] getRedoLogStatus()
```
    Exposes states of redo logs: current, active, inactive, unused ...
    
    Returns:
    
    array of: (redo log name | status) elements
  - getSwitchCounter
```
int getSwitchCounter()
```
    fetches counter of redo switches for the last day. If this number is high , like once in 3 minutes, the troubleshooting on the database level is required.
    
    Returns:
    
    counter
  - getLastLogMinerQueryDuration
```
Long getLastLogMinerQueryDuration()
```
    Returns:
    
    number of milliseconds last Log Miner query took
  - getCapturedDmlCount
```
int getCapturedDmlCount()
```
    Returns:
    
    number of captured DML since the connector is up
  - getLogMinerQueryCount
```
int getLogMinerQueryCount()
```
    Returns:
    
    number of Log Miner view queries since the connector is up
  - getAverageLogMinerQueryDuration
```
Long getAverageLogMinerQueryDuration()
```
    Returns:
    
    average duration of Log Miner view query
  - getLastProcessedCapturedBatchDuration
```
Long getLastProcessedCapturedBatchDuration()
```
    Log Miner view query returns number of captured DML , Commit and Rollback. This is what we call a batch.
    
    Returns:
    
    duration of the last batch processing, which includes parsing and dispatching
  - getProcessedCapturedBatchCount
```
int getProcessedCapturedBatchCount()
```
    Log Miner view query returns number of captured DML , Commit and Rollback. This is what we call a batch.
    
    Returns:
    
    number of all processed batches , which includes parsing and dispatching
  - getAverageProcessedCapturedBatchDuration
```
Long getAverageProcessedCapturedBatchDuration()
```
    Returns:
    
    average time of processing captured batch from Log Miner view
  - getBatchSize
```
int getBatchSize()
```
    Maximum number of entries in Log Miner view to fetch. This is used to set the diapason of the SCN in mining query. If difference between "start SCN" and "end SCN" to mine exceeds this limit, end SCN will be set to "start SCN" + batchSize
    
    Returns:
    
    the limit
  - setBatchSize
```
void setBatchSize(int size)
```
    this gives ability to manipulate number of entries in Log Miner view to fetch. It has limits to prevent abnormal values
    
    Parameters:
    
    size - limit
  - getMillisecondToSleepBetweenMiningQuery
```
Integer getMillisecondToSleepBetweenMiningQuery()
```
    Returns:
    
    number of milliseconds for connector to sleep before fetching another batch from the Log Miner view
  - setMillisecondToSleepBetweenMiningQuery
```
void setMillisecondToSleepBetweenMiningQuery(Integer milliseconds)
```
    sets number of milliseconds for connector to sleep before fetching another batch from the Log Miner view
    
    Parameters:
    
    milliseconds - to sleep
  - changeSleepingTime
```
void changeSleepingTime(boolean increment)
```
    change sleeping time
    
    Parameters:
    
    increment - true to add, false to deduct
