Channel attributes supported by the JSON CCDT

A list of the client connection channel attributes supported by the JSON CCDT. This list is a subset of the attributes supported by the binary CCDT.

Attribute mapping

These attributes are inserted into the following channel object:

{ "channel": [ {$CHANNEL_1_KEY_VALUE_LIST },..., {$CHANNEL_N_KEY_VALUE_LIST } ] }

where $CHANNEL_X_KEY_VALUE_LIST is a comma separated list of the attributes listed in the following table.

See JSON CCDT examples for basic use cases.

The JSON schema is shipped in /opt/mqm/lib/ccdt_schema.json. To discover what values are valid for each of the attributes look at the JSON schema.

The following table lists the JSON object, key, and data type, together with the corresponding binary channel attribute definition.

Attention: The required attributes are the channel name and channel type. If you also define portRange, the low and high attributes are also required.

JSON object	JSON key	JSON data type	Binary attribute definition
channel (array)	name	STRING	CHANNEL
channel (array)	type	STRING	CHLTYPE
channel.clientConnection	queueManager	STRING	QMNAME
channel.clientConnection.connection (array)	host	STRING	CONNAME
channel.clientConnection.connection	port	INT	CONNAME
channel.compression.header (array)	header	STRING	COMPHDR
channel.compression.message (array)	message	STRING	COMPMSG
channel.connectionManagement	affinity	STRING	AFFINITY
channel.connectionManagement	clientWeight	INT	CLNTWGHT
channel.connectionManagement	defaultReconnect	STRING	DEFRECON
channel.connectionManagement	disconnectInterval	INT	DISCINT
channel.connectionManagement	heartInterval	INT	HBINT
channel.connectionManagement	keepAliveInterval	INT	KAINT
channel.connectionManagement	sharingConversations	INT	SHARECNV
channel.connectionManagement.localAddress (array)	host	STRING	LOCLADDR
channel.connectionManagement.localAddress (array)	port	INT	LOCLADDR
channel.connectionManagement.localAddress.portRange	high	INT	LOCLADDR
channel.connectionManagement.localAddress.portRange	low	INT	LOCLADDR
channel.exits.receive (array)	name	STRING	RCVEXIT
channel.exits.receive (array)	userData	STRING	RCVDATA
channel.exits.security	name	STRING	SCYEXIT
channel.exits.security	userData	STRING	SCYDATA
channel.exits.send (array)	name	STRING	SENDEXIT
channel.exits.send (array)	userData	STRING	SENDDATA
channel.general	description	STRING	DESCR
channel.general	maximumMessageLength	INT	MAXMSGL
channel.timestamps	altered	STRING	ALTDATE and ALTTIME
channel.transmissionSecurity	certificateLabel	STRING	CERTLABL
channel.transmissionSecurity	certificatePeerName	STRING	SSLPEER
channel.transmissionSecurity	cipherSpecification	STRING	SSLCIPH

Notes:

channel.connectionManagement.localAddress can be defined as one of the following combinations of keys:
- host and port
- host and portRange
- port
- portRange
The channel.timestamps altered JSON key is optional and, if not defined, the value defaults to the JSON CCDT file last modified time. However, if the environment is configured to fetch the CCDT from a URL, the default value is the time the file was last downloaded.
channel.clientConnection.connection must include both host and port keys.
The altered key is a single string that encapsulates both ALTDATE and ALTTIME attributes.
The transport type can only be TCP, therefore the following attributes are not defined in the schema:
- TRPTYPE
- USERID
- PASSWORD
- MODENAME
- TPNAME
