CCDTUrlOffset (MQLONG)

CCDTUrlOffset is the offset in bytes, from the start of the MQCNO structure, to a string which contains a URL that identifies the location of the client connection channel table to use for the connection. The offset can be positive or negative and the initial value of the field is zero.

Use CCDTUrlOffset only when the application issuing the MQCONNX call is running as an IBM® MQ MQI client.

Important: You can use only one of CCDTUrlPtr and CCDTUrlOffset. The call fails with reason code MQRC_CCDT_URL_ERROR if both fields are nonzero.

This is a programmatic alternative to setting the MQCHLLIB and MQCHLTAB environment variables.

If the application is not running as an client, CCDTUrlOffset is ignored.

This field is ignored if Version is less than MQCNO_VERSION_6.
