Method Detail

getMaxStuckThreadTime

int getMaxStuckThreadTime()

The number of seconds that a thread must be continually working before this server diagnoses the thread as being stuck.

For example, if you set this to 600 seconds, WebLogic Server considers a thread to be "stuck" after 600 seconds of continuous use.

Returns:

The MaxStuckThreadTime value

Default Value:

600

Maximum Value:

java.lang.Integer.MAX_VALUE

Minimum Value:

0

setMaxStuckThreadTime

void setMaxStuckThreadTime(int time)

Sets the value of the MaxStuckThreadTime attribute.

Parameters:

time - The new stuckThreadMaxTime value in seconds

See Also:

getMaxStuckThreadTime()

getStuckThreadCount

int getStuckThreadCount()

The number of stuck threads after which the server is transitioned into FAILED state. There are options in OverloadProtectionMBean to suspend and shutdown a FAILED server. By default, the server continues to run in FAILED state.

If the StuckThreadCount value is set to zero then the server never transitions into FAILED server irrespective of the number of stuck threads.

Returns:

The StuckThreadCount value

Default Value:

0

Maximum Value:

java.lang.Integer.MAX_VALUE

Minimum Value:

0

setStuckThreadCount

void setStuckThreadCount(int count)

Sets the value of the StuckThreadCount attribute.

Parameters:

count - The new StuckThreadCount value

See Also:

getStuckThreadCount()

getHeapDumpingOnDeadlock

boolean getHeapDumpingOnDeadlock()

Get the attribute of HeapDumpingOnDeadlock

Returns:

the HeapDumpingOnDeadlock value

Default Value:

false

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

setHeapDumpingOnDeadlock

void setHeapDumpingOnDeadlock(boolean enabled)

Sets the attribute of the HeapDumpingOnDeadlock. True: enabled. False: disabled If enabled and deadlock occurrs, it will generate heap dump to the directory of the value from WLDFServerDiagnosticMBean.getDiagnosticDumpsDir().

Parameters:

enabled -

Default Value:

false

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

getHeapDumpingOnMaxStuckThread

boolean getHeapDumpingOnMaxStuckThread()

Get the attribute of HeapDumpingOnMaxStuckThread

Returns:

the HeapDumpingOnMaxStuckThread value

See Also:

getStuckThreadCount()

Default Value:

false

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

setHeapDumpingOnMaxStuckThread

void setHeapDumpingOnMaxStuckThread(boolean enabled)

Sets the value of the HeapDumpingOnMaxStuckThread. True: enabled. False: disabled

If enabled and max stuck thread limit is reached, it will generate heap dump to the directory of the value from WLDFServerDiagnosticMBean.getDiagnosticDumpsDir().

Parameters:

enabled -

See Also:

getStuckThreadCount()

Default Value:

false

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.
