Class GetThreadDumpOp

java.lang.Object
com.highdeal.admin.hci.GetThreadDumpOp
All Implemented Interfaces:
MessageOperation, XMLMarshallable

public class GetThreadDumpOp extends 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'

    • GetThreadDumpOp

      public GetThreadDumpOp()
  • Method Details

    • getName

      public 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(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(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
      Sets the attributes of the XML representation of the element being processed.
      Specified by:
      setAttributes in interface XMLMarshallable
      Parameters:
      atts - The XML attributes of the current element
