The XA resource manager calls ax_unreg() to inform a
transaction manager that it has completed work on a local transaction. The
local transaction was started after receiving a NULLXID from
ax_reg().
The XA resource manager indicates that it uses the dynamic registration
facility by setting the TMREGISTER value in the flags
element of its xa_switch_t structure.
The name of the service program that contains ax_reg() and
ax_unreg() must be provided to the XA resource manager in the
*xa_info parameter of the db2xa_open() call.
Parameters
rmid
(Input) The resource manager identifier that was generated by a transaction
manager when the resource manager was opened.
flags
(Input) The flags argument must be set to this value.
TMNOFLAGS: 0x00000000L No flags are defined for this function.
