kbytes - If the kbytes parameter is non-zero, a checkpoint will be performed if more than kbytes of log data have been written since the last checkpoint.

getKBytes

public int getKBytes()

Return the checkpoint log data threshold, in kilobytes.

This method may be called at any time during the life of the application.

Returns:

The checkpoint log data threshold, in kilobytes.

setMinutes

public void setMinutes(int min)

The default is 0 for this class and the database environment.

Parameters:

min - If the min parameter is non-zero, a checkpoint is performed if more than min minutes have passed since the last checkpoint.

getMinutes

public int getMinutes()

Return the checkpoint time threshold, in minutes.

Returns:

The checkpoint time threshold, in minutes.

setForce

public void setForce(boolean force)

Configure the checkpoint force option.

The default is false for this class and the BDB JE environment.

Parameters:

force - If set to true, force a checkpoint, even if there has been no activity since the last checkpoint.
