MQMD settings in queue manager response messages

A queue manager uses these settings of fields in the message descriptor (MQMD) when sending a reply to a publication message. All other fields in the MQMD are set to their default values.

Report

Report is set to all zeros.

MsgType

MsgType is set to MQMT_REPLY.

Format

Format is set to MQFMT_RF_HEADER_2

MsgId

The setting of MsgId depends on the Report options in the original command message. By default, it is set to MQMI_NONE, so that the queue manager generates a unique value.

CorrelId

The setting of CorrelId depends on the Report options in the original command message. By default, this means that the CorrelId is set to the same value as the MsgId of the command message. This can be used to correlate commands with their responses.

Priority

Priority is set to the same value as in the original command message.

Persistence

Persistence is set to the value set in the original command message.

Expiry

Expiry is set to the same value as in the original command message received by the queue manager.

PutApplType

PutApplType is set to MQAT_BROKER.

PutApplName

PutApplName is set to the first 28 characters of name of the queue manager.

Other context fields are set as if generated with MQPMO_PASS_IDENTITY_CONTEXT.
