Using the ORB
To use the Object Request Broker (ORB) effectively, you must understand the properties that control the behavior of the ORB.
The following table lists the property values that you can use to customize the behavior of the
ORB. All property values are specified as strings. Click on the links for more information about
each property.
| System property | Usage |
|---|---|
| -Dcom.ibm.CORBA.AcceptTimeout | Set a timeout value for an accept() call. |
| -Dcom.ibm.CORBA.AllowUserInterrupt | Allow an interrupt to a remote method call. |
| -Dcom.ibm.CORBA.BufferSize | Set the number of bytes to read of a GIOP message. |

| -Dcom.ibm.CORBA.GIOPAddressingDisposition | Set the GIOP address disposition. |
| -Dcom.ibm.CORBA.InitialReferencesURL | Configure ORB to use a server based URL instead of the bootstrap approach. Note: This property
is deprecated.

| -Dcom.ibm.CORBA.RequestTimeout | Set the timeout value for a Request message. |
| -Dcom.ibm.CORBA.SendingContextRunTimeSupported | Control the CodeBase SendingContext RunTime service. |
| -Dcom.ibm.CORBA.SendVersionIdentifier | Determine the partner version of ORB. |
| -Dcom.ibm.CORBA.ServerSocketQueueDepth | Set the maximum queue length for incoming connection requests. |
| -Dcom.ibm.CORBA.ShortExceptionDetails | Control the output from a SystemException reply. |
| -Dcom.ibm.tools.rmic.iiop.Debug | Set the rmic tool to map fully qualified class names to short names. |
| -Dcom.ibm.tools.rmic.iiop.SkipImports | Set the rmic tool to generate classes with fully qualified names only. |
| -Dorg.omg.CORBA.ORBid | Set a unique identifier for the ORB. |
| -Dorg.omg.CORBA.ORBListenEndpoints | Identify the set of endpoints on which the ORB listens for requests. |
| -Dorg.omg.CORBA.ORBServerId | Set the same value for all ORB instances that are running in the same server. |
| com.ibm.CORBA.BootstrapHost | This property is deprecated. It is replaced by -ORBInitRef and -ORBDefaultInitRef. |
| com.ibm.CORBA.BootstrapPort | This property is deprecated. It is replaced by -ORBInitRef and -ORBDefaultInitRef. |
This table shows the Java™ properties
defined by Oracle Corporation that are now deprecated, and the IBM® properties that have replaced
