Data Queue APIs--Categories - FTP Directory Listing - IBM

Create User Queue (QUSCRTUQ) API
lowercase, or mixed case. The API automatically converts it to uppercase.
Queue type
INPUT; CHAR(1)
The sequence in which messages are to be dequeued from the queue. The valid values are:
F
First-in first-out
K
Keyed
L
Last-in first-out
Key length
INPUT; BINARY(4)
The length in bytes of the message key from 1 to 256 if you specify the queue type as keyed. If you
specify that the queue is not a keyed queue, the value must be 0.
Maximum message size
INPUT; BINARY(4)
The maximum allowed size of messages to be placed on the queue. The API truncates messages that
are longer than the value you specify. The maximum size allowed is 64 000 bytes.
Initial number of messages
INPUT; BINARY(4)
The initial number of messages that the queue can contain.
Additional number of messages
INPUT; BINARY(4)
The amount to increase the maximum number of messages value when the queue is full. When this
parameter is set to 0, the queue is not extended if an overflow occurs and an error message is sent to
the program attempting to place a message on the queue.
Public authority
INPUT; CHAR(10)
The authority you give to the users who do not have specific private or group authority to the user
queue. Once the user queue has been created, its public authority stays the same when it is moved to
another library or restored from backup media.
If the replace parameter is used and a user queue exists to be replaced, this parameter is ignored. All
authorities are transferred from the replaced user queue to the new one.
The valid values for this parameter are:
*ALL
The user can perform all authorized operations on the user queue.
