DbSpace(Environment env, boolean quiet, boolean details, boolean sorted) Creates a DbSpace object for calculating utilization using an open Environment.

Method Summary

Modifier and Type	Method and Description
static void	main(java.lang.String[] argv)
void	print(java.io.PrintStream out) Calculates utilization and prints a report to the given output stream.
void	setEndFile(long endFile) Sets the ending file number, which is an upper bound on the range of files for which utilization is reported and (optionally) recalculated.
void	setRecalculate(boolean recalc) Sets the recalculation property, which if true causes a more expensive recalculation of utilization to be performed for debugging purposes.
void	setStartFile(long startFile) Sets the start file number, which is a lower bound on the range of files for which utilization is reported and (optionally) recalculated.
void	setTime(long time) Sets the time for calculating expired data.

Method Detail

main

public static void main(java.lang.String[] argv)
                 throws java.lang.Exception

Throws:

java.lang.Exception

setRecalculate

public void setRecalculate(boolean recalc)

Sets the recalculation property, which if true causes a more expensive recalculation of utilization to be performed for debugging purposes. This property is false by default.

setStartFile

public void setStartFile(long startFile)

Sets the start file number, which is a lower bound on the range of files for which utilization is reported and (optionally) recalculated. By default there is no lower bound.

setEndFile

public void setEndFile(long endFile)

Sets the ending file number, which is an upper bound on the range of files for which utilization is reported and (optionally) recalculated. By default there is no upper bound.

setTime

public void setTime(long time)

Sets the time for calculating expired data.

print

public void print(java.io.PrintStream out)
           throws DatabaseException

Calculates utilization and prints a report to the given output stream.

Throws:

DatabaseException
