Constructor Detail

SqlQueryMXBeanImpl

public SqlQueryMXBeanImpl(GridKernalContext ctx)

Parameters:

ctx - Context.

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.

getSqlGlobalMemoryQuotaBytes

public Long getSqlGlobalMemoryQuotaBytes()

Gets global query quota.

Specified by:

getSqlGlobalMemoryQuotaBytes in interface SqlQueryMXBean

Returns:

Global query quota as a long.

getSqlGlobalMemoryQuota

public String getSqlGlobalMemoryQuota()

Gets global query quota.

Specified by:

getSqlGlobalMemoryQuota in interface SqlQueryMXBean

Returns:

Global query quota.

setSqlGlobalMemoryQuota

public void setSqlGlobalMemoryQuota(String size)

Sets global query quota.

Specified by:

setSqlGlobalMemoryQuota in interface SqlQueryMXBean

Parameters:

size - Size of global memory pool for SQL queries.

getSqlFreeMemoryBytes

public long getSqlFreeMemoryBytes()

Gets the amount of memory available for SQL queries. This is equal to the SqlQueryMXBean.getSqlGlobalMemoryQuotaBytes() minus the amount of memory currently occupied by the queries.

Specified by:

getSqlFreeMemoryBytes in interface SqlQueryMXBean

Returns:

Amount of memory bytes available for SQL queries.

getSqlQueryMemoryQuotaBytes

public Long getSqlQueryMemoryQuotaBytes()

Gets global query quota.

Specified by:

getSqlQueryMemoryQuotaBytes in interface SqlQueryMXBean

Returns:

Global query quota as a long.

getSqlQueryMemoryQuota

public String getSqlQueryMemoryQuota()

Gets global query quota.

Specified by:

getSqlQueryMemoryQuota in interface SqlQueryMXBean

Returns:

Global query quota.

setSqlQueryMemoryQuota

public void setSqlQueryMemoryQuota(String size)

Sets per-query memory quota.

Specified by:

setSqlQueryMemoryQuota in interface SqlQueryMXBean

Parameters:

size - Size of per-query memory quota in bytes, kilobytes, megabytes, or percentage of the max heap.

isSqlOffloadingEnabled

public boolean isSqlOffloadingEnabled()

Gets offloading flag.

Specified by:

isSqlOffloadingEnabled in interface SqlQueryMXBean

Returns:

Flag whether query disk offloading is enabled.

setSqlOffloadingEnabled

public void setSqlOffloadingEnabled(boolean enabled)

Sets offloading flag.

Specified by:

setSqlOffloadingEnabled in interface SqlQueryMXBean

Parameters:

enabled - The value whether offloading flag is enabled.
