WebSphere MQ Everyplace connections

WebSphere MQ Everyplace supports a method of establishing logical connections between queue managers, in order to send or receive data.

WebSphere MQ Everyplace clients and servers can communicate over two types of connections, peer channels and client/server channels.

Client/server channels have the following attributes:

Peer channels have the following attributes:

Connections can have various attributes or characteristics, such as authentication, cryptography, compression, or the transmission protocol to use. Different connections can use different characteristics. Each connection can have its own value set for each of the following attributes:

Authenticator
This attribute causes authentication to be performed. This is a security function that challenges the putting application environment or user to prove their identity.
Cryptor
This attribute causes encryption and decryption to be performed on messages passing through the connection. This is a security function that encodes the messages during transit so that you cannot read them without the decoding information.
Compressor
This attribute causes compression and decompression to be performed on messages passing through the connection. This attempts to reduce the size of messages while they are being transmitted and stored.
Destination
The server and port number for the connection.

Typically, authentication only occurs when setting up the connection. All flows normally use compressors and cryptors.

For more detailed information about connections see Connections. Also, for more information about authenticators, compressors, and cryptors, see Security.

You can establish WebSphere MQ Everyplace connections using a variety of protocols allowing them to connect in a number of different ways, for example:

WebSphere MQ Everyplace implements the communications protocols as a set of adapters, with one adapter for each of the supported protocols. This enables you to add new protocols.
