Problem summary

  • Using the Java Attach API, sometimes called the "late attach"
    capability, an application can connect to another "target"
    virtual machine. The application can then load an agent
    application into the target virtual machine to, for example,
    perform tasks such as status monitoring.
    
    Before the Java Attach API, code for agent applications, such as
    JMX agents or JVMTI agents, was loaded during virtual machine
    startup by specifying special startup parameters. Having to
    specify startup parameters might not be convenient for using
    agents on applications that are already running, such as
    WebSphere© Application Servers. With the Java Attach API an
    agent can be loaded at any time, by specifying the process ID of
    the target virtual machine.
    
    A description of the Java Attach API package
    com.sun.tools.attach    including options for use and security
    considerations, can be found in the IBM User Guide for your Java
    release and Operating System, under     "Developing Java
    Applications"-> "Support for the Java Attach API".
    
    This new function is available from:
        Java 5 SR10, disabled by default except with Java 5 SR10 on
    z/OS
        Java 6 SR6,  enabled by default except on z/OS
        Java 6 R26 and Java 7 GA, enabled by default on all
    platforms.
    this function can be enabled or disabled where necessary by
    using a system property.  Consult the User Guide for more
    information.
