Managing Object Request Brokers

Use this task to manage Object Request Brokers (ORB). An ORB manages the interaction between clients and servers using the Internet InterORB Protocol (IIOP).

Default property values are set when the product starts and the Java Object Request Broker (ORB) service is initialized. These properties control the run-time behavior of the ORB and can also affect the behavior of product components that are tightly integrated with the ORB, such as security. It might be necessary to modify some ORB settings under certain conditions.

Every request or response exchange consists of a client-side ORB and a server-side ORB. It is important to set the ORB properties for both sides as necessary.

After an ORB instance has been established in a process, changes to ORB properties do not affect the behavior of the running ORB instance. The process must be stopped and restarted for the modified properties to take effect.

A list of possible tasks for managing ORB follows:

(dependent on configuration)

• Adjust timeout settings to improve handling of network failures. See Object Request Broker service settings for more information. Before making these adjustments, read Object Request Broker tuning guidelines.

• Adjust thread-pool settings used by the ORB for handling Internet InterORB Protocol (IIOP) connections. See Thread pool settings for more information.

• If problems with the ORB arise, see Object request broker component troubleshooting tips.

  For help in troubleshooting, see Object Request Broker communications trace.
