Outbound transport options

There are a number of general considerations that apply to configuring outbound transports for use when establishing network connections with other messaging engines or with WebSphere MQ queue manager receiver channels.

The configuration of network transports for service integration is managed through the transport channel service. However, because manipulation of outbound transport options is considered an advanced administrative operation, some configuration can only be done through the wsadmin tool.

For your convenience, a number of outbound transport chains are preconfigured when an application server is created from the default server template, or when a client container is started.

Outbound transport chains are used for either:

When establishing a network connection, the type of channels and their order in the outbound transport chain used must match that of those in the inbound transport chain for the server to which connection is made. For example, an outbound HTTP tunneling chain is only suitable for establishing connections with an inbound HTTP tunneling chain.

The following chains are for use during the bootstrap process:
BootstrapBasicMessaging
Used to establish bootstrap connections to inbound chains configured for TCP-only connections to an application server, such as the InboundBasicMessaging chain.
BootstrapSecureMessaging
Used to establish secure connections using secure sockets layer (SSL) based encryption. The SSL configuration used is taken from the default SSL repertoire when used in an application server environment or from a configuration file when used by the client container. See Secure transport considerations for more information. This chain can be used for establishing bootstrap connections to inbound chains that are configured to use SSL, for example, the InboundSecureMessaging chain. Success in establishing such a connection depends on a compatible set of SSL credentials being associated with both this bootstrap outbound chain and also with the inbound chain to which the connection is being made.
BootstrapTunneledMessaging
Used to connect when tunneling through HTTP.
BootstrapTunneledSecureMessaging
Used to establish bootstrapping connections that are tunneled through secure HTTP (HTTPS). Like the BootstrapSecureMessaging outbound chain, this chain also derives its SSL configuration from the default SSL repertoire when used in an application server or from a configuration file when used in the client container. See Secure transport considerations.

The outbound chains that an application server uses for bootstrap operations are defined when the server is defined. They can be altered, or new bootstrap chains can be defined, using the wsadmin tool. See Defining outbound chains for bootstrapping and Defining outbound chains for WebSphere MQ interoperation.

Bootstrap outbound chains used by a client container are not configurable. Some attributes of outbound chains that use SSL encryption protocols are, however, customizable. For more information, see Secure transport considerations.

The names of outbound bootstrap chains are needed when configuring:
The following chains can be used when establishing a network connection to a WebSphere MQ queue manager receiver channel:
OutboundBasicMQLink
Used to establish connections with WebSphere MQ queue manager receiver channels.
OutboundSecureMQLink
Used to establish connections with WebSphere MQ queue manager receiver channels that have been secured using SSL. The SSL configuration used is taken from the default SSL repertoire for the application server being used to contact the queue manager.

The names of outbound chains used for WebSphere MQ interoperation are needed when configuring the transport chain of a WebSphere MQ link.
