quotation marks. For example, if you wanted to specify a correlation ID of
My "New" ID, you would need to enter the following:
-CID "My ""New"" ID"
When a correlation identifier is specified for a source, the adapter retrieves the
first message on the queue with that correlation ID. If no argument is supplied,
the correlation ID of the first message retrieved is used.
If the Correlation ID adapter command (
-CID) is specified and is used with the
Message ID adapter command (
-MID), the retrieved messages begin with the first
message on the queue that has the specified message ID and the correlation ID.
Additional messages are retrieved that have the same message ID and correlation
ID. If no correlation ID is specified, the message is identified only by the message ID.
When a correlation identifier is specified for a data target, the adapter places the
message on the queue with the assigned correlation identifier.
Default Header (-DH)
The Default Header adapter command (-DH) specifies that the default IBM
WebSphere MQ Message Descriptor (MQMD) is used as the message descriptor for
data targets.
-DH
Any null rules (=NONE) in the mapped header field are ignored and the default
MQMD values generated by the queue manager are used. Any non-null header
fields are set in the MQMD to replace the default MQMD values. The only exception
to this is fields that describe the origin and identity context of the message.
Fields describing the origin context of the message are the following (listed in the
order in which they appear in the example type tree, mq.mtt):
PutApplType
PutApplName
PutDate
PutTime
ApplOriginData
Fields describing the identity context of the message are the following (listed in
the order in which they appear in the example type tree, mq.mtt):
UserIdentifier
AccountingToken
ApplIdentityData
