Method Detail

getLongQueryWarningTimeout

public long getLongQueryWarningTimeout()

Specified by:

getLongQueryWarningTimeout in interface SqlQueryMXBean

Returns:

Timeout in milliseconds after which long query warning will be printed.

setLongQueryWarningTimeout

public void setLongQueryWarningTimeout(long longQryWarningTimeout)

Sets timeout in milliseconds after which long query warning will be printed.

Specified by:

setLongQueryWarningTimeout in interface SqlQueryMXBean

Parameters:

longQryWarningTimeout - Timeout in milliseconds after which long query warning will be printed.

getLongQueryTimeoutMultiplier

public int getLongQueryTimeoutMultiplier()

Specified by:

getLongQueryTimeoutMultiplier in interface SqlQueryMXBean

Returns:

Long query timeout multiplier.

setLongQueryTimeoutMultiplier

public void setLongQueryTimeoutMultiplier(int longQryTimeoutMultiplier)

Sets long query timeout multiplier. The warning will be printed after: - timeout; - timeout * multiplier; - timeout * multiplier * multiplier; - etc. If the multiplier <= 1, the warning message is printed once.

Specified by:

setLongQueryTimeoutMultiplier in interface SqlQueryMXBean

Parameters:

longQryTimeoutMultiplier - Long query timeout multiplier.

getResultSetSizeThreshold

public long getResultSetSizeThreshold()

Specified by:

getResultSetSizeThreshold in interface SqlQueryMXBean

Returns:

Threshold for the number of rows of the result, when count of fetched rows is bigger than the threshold warning will be printed.

setResultSetSizeThreshold

public void setResultSetSizeThreshold(long rsSizeThreshold)

Sets threshold result's row count, when count of fetched rows is bigger than the threshold warning will be printed.

Specified by:

setResultSetSizeThreshold in interface SqlQueryMXBean

Parameters:

rsSizeThreshold - Threshold result's row count, when count of fetched rows is bigger than the threshold warning will be printed.

getResultSetSizeThresholdMultiplier

public int getResultSetSizeThresholdMultiplier()

Gets result set size threshold multiplier. The warning will be printed after: - size of result set > threshold; - size of result set > threshold * multiplier; - size of result set > threshold * multiplier * multiplier; - etc. If the multiplier <= 1, the warning message is printed once during query execution and the next one on the query end.

Specified by:

getResultSetSizeThresholdMultiplier in interface SqlQueryMXBean

Returns:

Result set size threshold multiplier.

setResultSetSizeThresholdMultiplier

public void setResultSetSizeThresholdMultiplier(int rsSizeThresholdMultiplier)

Sets result set size threshold multiplier.

Specified by:

setResultSetSizeThresholdMultiplier in interface SqlQueryMXBean

Parameters:

rsSizeThresholdMultiplier - Result set size threshold multiplier.
