- 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
  - getTotalCapturedDmlCount
```
long getTotalCapturedDmlCount()
```
    Returns:
    
    number of captured DML since the connector is up
  - getMaxDurationOfFetchingQuery
```
Long getMaxDurationOfFetchingQuery()
```
    Returns:
    
    average duration of Log Miner view query
  - getLastDurationOfFetchingQuery
```
Long getLastDurationOfFetchingQuery()
```
    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 fetching
  - getFetchingQueryCount
```
long getFetchingQueryCount()
```
    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
  - getMaxCapturedDmlInBatch
```
Long getMaxCapturedDmlInBatch()
```
    Returns:
    
    max number of DML captured during connector start time
  - getLastBatchProcessingDuration
```
long getLastBatchProcessingDuration()
```
    Returns:
    
    time of processing the last captured batch
  - getLastCapturedDmlCount
```
int getLastCapturedDmlCount()
```
    Returns:
    
    number of captured DL during last mining session
  - 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
  - changeBatchSize
```
void changeBatchSize(boolean increment)
```
  - setRecordMiningHistory
```
void setRecordMiningHistory(boolean doRecording)
```
    this flag turns on recording of captured incremental changes. It creates an overhead on CPU and takes disk space
    
    Parameters:
    
    doRecording - true - record
  - getRecordMiningHistory
```
boolean getRecordMiningHistory()
```
    this flag indicates whether log mining is being recorded by HistoryRecorder
  - getMaxBatchProcessingThroughput
```
long getMaxBatchProcessingThroughput()
```
    This represents the maximum number of entries processed per second from LogMiner sessions. Entries include things such as DMLs, commits, rollbacks, etc.
    
    Returns:
    
    the maximum number of entries processed per second from LogMiner sessions
  - getAverageBatchProcessingThroughput
```
long getAverageBatchProcessingThroughput()
```
    This represents the average number of entries processed per second from LogMiner sessions. Entries include things such as DMLs, commits, rollbacks, etc.
    
    Returns:
    
    the average number of entries per second from LogMiner sessions
  - getLastBatchProcessingThroughput
```
long getLastBatchProcessingThroughput()
```
    This represents the number of entries processed per second in the last LogMiner session. Entries include things such as DMLs, commits, rollbacks, etc.
    
    Returns:
    
    the number of entries processed per second from last LogMiner session
  - getNetworkConnectionProblemsCounter
```
long getNetworkConnectionProblemsCounter()
```
    Returns:
    
    the number of connection problems detected
  - reset
```
void reset()
```
    Resets metrics.
  - getHoursToKeepTransactionInBuffer
```
int getHoursToKeepTransactionInBuffer()
```
    Returns:
    
    the number of hours to keep transaction in buffer before abandoning
  - setHoursToKeepTransactionInBuffer
```
void setHoursToKeepTransactionInBuffer(int hours)
```
    Set the number of hours to retain transaction in buffer prior to abandoning
    
    Parameters:
