Notes:
1. QSGDISP (GROUP) objects are not searched.
2. LIKE is ignored if QSGDISP(COPY) is specified.
NOREPLACE and REPLACE
Whether the existing definition, and with the same disposition, is to be
replaced with this one. This is optional. The default is NOREPLACE. Any
object with a different disposition is not changed.
NOREPLACE
The definition should not replace any existing definition of the
same name.
REPLACE
The definition should replace any existing definition of the same
name. If a definition does not exist, one is created.
If you use the REPLACE option, all queues that use this storage
class must be empty.
PSID(integer)
The page set identifier that this storage class is to be associated with. If
you do not specify this, the value is taken from the default storage class
SYSTEMST.
Note: No check is made that the page set has been defined; an error will
be raised only when you try to put a message to a queue that
specifies this storage class (MQRC_PAGESET_ERROR).
The string consists of two numeric characters, in the range 00 through 99.
See “DEFINE PSID” on page 105.
QSGDISP
Specifies the disposition of the object in the group.
QSGDISP ALTER DEFINE
COPY The object definition resides on the page set
of the queue manager that executes the
command. The object was defined using a
command that had the parameters
QSGDISP(COPY). Any object residing in the
shared repository, or any object defined using
a command that had the parameters
QSGDISP(QMGR), is not affected by this
command.
The object is defined on the page set of the
queue manager that executes the command
using the QSGDISP(GROUP) object of the
same name as the ’LIKE’ object.
GROUP The object definition resides in the shared
repository. The object was defined using a
command that had the parameters
QSGDISP(GROUP). Any object residing on
the page set of the queue manager that
executes the command (except a local copy
of the object) is not affected by this
command. If the command is successful, the
following command is generated and sent to
all active queue managers in the
queue-sharing group to cause them to refresh
local copies on page set 0:
DEFINE STGCLASS(name)
REPLACE QSGDISP(COPY)
The object definition resides in the shared
repository. This is allowed only if the queue
manager is in a queue-sharing group. If the
definition is successful, the following
command is generated and sent to all active
queue managers in the queue-sharing group
to cause them to make or refresh local copies
on page set 0:
DEFINE STGCLASS(name)
REPLACE QSGDISP(COPY)
DEFINE STGCLASS
