Create User Queue (QUSCRTUQ) API
Does not contain
library name Library name *USER
None; error is
returned
Note: The QALWUSRDMN system value lists the libraries into which the user domain objects
can be created. The libraries include special value *ALL or a list of one or more library names.
Pointers
INPUT; CHAR(10)
Whether or not the user queue messages can contain pointer data or not. If this parameter is not
specified, *NO is assumed.
*YES
Messages can contain pointer and scalar data. Messages to be enqueued must be 16-byte
aligned, regardless of whether or not the message contains pointer data. Only user-domain
user queues can contain pointer data; therefore, queues that support pointers cannot be created
in or restored to a library that is not permitted by system value QALWUSRDMN. User
queues that can contain pointers cannot be saved to a release prior to Version 2 Release 3
Modification Level 0.
*NO
Messages can contain scalar data only. (User queues created prior to Version 2 Release 3
Modification Level 0 contain scalar data only). The user queue can be in either the system
domain or the user domain.
Optional Parameter Group 3
Number of queue extensions
INPUT; BINARY(4)
The maximum number of extensions allowed for the user queue. A value of -1 indicates that the
maximum number of extensions will be chosen by the machine. If this parameter is not specified, 0
is assumed.
Reclaim storage
INPUT; CHAR(1)
Whether storage reclaim will be attempted when the number of currently enqueued messages in the
user queue reaches zero. Allowable values are:
0
Do not reclaim storage when the user queues have no currently enqueued messages. 0 is the
default value.
1
Reclaim storage when the user queues have no currently enqueued messages.
