getStdoutSeverityLevel

public int getStdoutSeverityLevel()

The minimum severity of a message that the server sends to standard out. You must enable Log to Standard Out for this value to be relevant.

The ascending order of severities is as follows:

• INFO(64). Used for reporting normal operations.
• WARNING(32). A suspicious operation or configuration has occurred but it may not have an impact on normal operation.
• ERROR(16). A user error has occurred. The system or application is able to handle the error with no interruption, and limited degradation, of service.
• NOTICE(8). An INFO or WARNING-level message that is particularly important for monitoring the server. Only WebLogic Server subsystems write messages of this severity type.
• CRITICAL(4). A system or service error has occurred. The system is able to recover but there might be a momentary loss, or permanent degradation, of service.
• ALERT(2). A particular service is in an unusable state while other parts of the system continue to function. Automatic recovery is not possible; the immediate attention of the administrator is needed to resolve the problem.
• EMERGENCY(1). The server is in an unusable state. This severity indicates a severe system failure or panic.

A dynamic MBean attribute

setStdoutSeverityLevel

public void setStdoutSeverityLevel(int severityLevel)
                            throws javax.management.InvalidAttributeValueException,
                                   DistributedManagementException

Sets the stdoutSeverityLevel attribute of the KernelMBean object

Parameters:

severityLevel - The new stdoutSeverityLevel value

Throws:

javax.management.InvalidAttributeValueException - Description of the Exception

DistributedManagementException - Description of the Exception

isStdoutDebugEnabled

public boolean isStdoutDebugEnabled()

Determines whether the server sends messages of the DEBUG severity to standard out in addition to the log file. You must enable Log to Standard Out for this property to be relevant.

A dynamic MBean attribute

Default Value: false

Returns:

The stdoutDebugEnabled value

setStdoutDebugEnabled

public void setStdoutDebugEnabled(boolean enable)
                           throws DistributedManagementException

Sets the stdoutDebugEnabled attribute of the KernelMBean object

Parameters:

enable - The new stdoutDebugEnabled value

Throws:

DistributedManagementException - Description of the Exception

isLogRemoteExceptionsEnabled

public boolean isLogRemoteExceptionsEnabled()

Determines whether the server message log includes exceptions that are raised in remote systems.

A dynamic MBean attribute

Default Value: true

Returns:

The logRemoteExceptionsEnabled value

setLogRemoteExceptionsEnabled

public void setLogRemoteExceptionsEnabled(boolean enable)
                                   throws DistributedManagementException

Sets the logRemoteExceptionsEnabled attribute of the KernelMBean object

Parameters:

enable - The new logRemoteExceptionsEnabled value

Throws:

DistributedManagementException - Description of the Exception

isInstrumentStackTraceEnabled

public boolean isInstrumentStackTraceEnabled()

Determines whether the server returns stack traces for RMI calls that generate exceptions.

With this attribute enabled, if a client issues an RMI call to a server subsystem or to a module running within the server, and if the subsystem or module generates an exception that includes a stack trace, the server will return the exception as well as the stack trace. With this attribute disabled, the server will return the exception without the stack trace details.

A dynamic MBean attribute

Default Value: true

Returns:

The instrumentStackTraceEnabled value

setInstrumentStackTraceEnabled

public void setInstrumentStackTraceEnabled(boolean enable)
                                    throws DistributedManagementException

Sets the instrumentStackTraceEnabled attribute of the KernelMBean object

Parameters:

enable - The new instrumentStackTraceEnabled value

Throws:

DistributedManagementException - Description of the Exception
