Overview for MQEPH
Availability: All WebSphere® MQ platforms.
Purpose: The MQEPH structure describes the additional
data that is present in a message when that message is a programmable
command format (PCF) message. The PCFHeader
field
defines the PCF parameters that follow this structure and this allows
you to follow the PCF message data with other headers.
Format name: MQFMT_EMBEDDED_PCF
Character set and encoding: Data in MQEPH must
be in the character set given by the CodedCharSetId
queue-manager
attribute and encoding of the local queue manager given by MQENC_NATIVE.
CodedCharSetId
and Encoding
fields
in: - The MQMD (if the MQEPH structure is at the start of the message data), or
- The header structure that precedes the MQEPH structure (all other cases).
Usage: You cannot use MQEPH structures to send commands to the command server or any other queue manager PCF-accepting server.
Similarly, the command server or any other queue manager PCF-accepting server do not generate responses or events containing MQEPH structures.
