Class GetThreadDumpOp

java.lang.Object

com.highdeal.admin.hci.GetThreadDumpOp

All Implemented Interfaces:

MessageOperation, XMLMarshallable

public class GetThreadDumpOp
extends java.lang.Object
implements MessageOperation

This operation allows you to get the dump of all threads of an instance.
The thread dump done by the JVM provides kernel information that the API doesn't, like:

• the kernel thread priority "prio"
• the kernel thread identifier "tid"
• the lock information

So, the dump in the result of this operation:

• "prio" is the thread priority returned by the API
• "tid" is the hash of the thread (hexa)
• the lock information aren't returned

The value of "tid" isn't the value returned to the method Thread.getId() because when a thread is terminated, this identifier may be reused.

As of SAP CC 4.1 SP 1 and if the THREAD_DUMP_ENABLED system parameter is set to true, the dump command also triggers the generation of a thread dump file for each specified instance (or for all running instances when no argument is specified).

Each thread dump file is generated:

• In the output path of each concerned instance, defined using the THREAD_DUMP_OUTPUT_PATH system parameter
• Using the following naming pattern: <instanceId>_<date>_ondemand.zip, where:
• instanceId = <instanceType>#<instanceNumber> (e.g. updater#1, dispatcher#1, rater#2, and so on)
• date corresponds to the java date and uses the following pattern : yyyy-MM-dd'T'HH'h'mm'm'ss's'

Method Detail

getName

public java.lang.String getName()

Description copied from interface: MessageOperation

Gets the XML name of the service operation. This name identifies the operation request in the HCI messages. It is used to marshal the Java object representing an HCI operation into an XML representation that can be exchanged via the HCI communication interface between your client application and the SAP CC system.

Example

• activateAll
• ping

Specified by:

getName in interface MessageOperation

Returns:

The technical name of the HCI operation

addCharacterData

public void addCharacterData(java.lang.String data)

Description copied from interface: XMLMarshallable

Adds character data to the content element.

Specified by:

addCharacterData in interface XMLMarshallable

Parameters:

data - The character data to be added

addChild

public void addChild(java.lang.String tagName,
                     XMLMarshallable child)

Description copied from interface: XMLMarshallable

Adds a child to the object, the child representing the marshallable object which must be added to the element.

Specified by:

addChild in interface XMLMarshallable

Parameters:

tagName - The name of tag for the child

child - The child to be added

marshal

public void marshal(XMLOutputter output)

Description copied from interface: XMLMarshallable

Gives an XML representation of this object, including its children.

Specified by:

marshal in interface XMLMarshallable

Parameters:

output - The XML output to marshal the object into

setAttributes

public void setAttributes(XMLAttributes atts)

Description copied from interface: XMLMarshallable
