Changes to the system programming interface

INQUIRE DISPATCHER

The EXEC CICS INQUIRE DISPATCHER command is changed to include the ACTXPTCBS and MAXXPTCBS options.
ACTXPTCBS(value)
displays the number of X8 and X9 mode open TCBs that are currently active (that is, allocated to a user task).
MAXXPTCBS(value)
displays the maximum number of X8 and X9 mode open TCBs that can exist concurrently in the CICS® region. The value can be in the range 1-999. You can reset this value by overtyping it with a different value.

INQUIRE PROGRAM

The EXEC CICS INQUIRE PROGRAM command is changed to include the XPLink value for the Runtime option.
Runtime
displays information about the runtime environment of the program. The new value in this list is:
XPLink
The program is a C or C++ program which has been compiled using the XPLINK option.
.

SET DISPATCHER

The EXEC CICS SET DISPATCHER command is changed to include the MAXXPTCBS option.
MAXXPTCBS(value)
specifies the maximum number of X8 and X9 mode open TCBs that can exist concurrently in the CICS region. The value specified can be in the range 1 to 999. If you reduce MAXXPTCBS from its previously defined value, and the new value is less than the number of open TCBs currently allocated, CICS detaches TCBs to achieve the new limit only when they are freed by user tasks. Transactions are not abended to allow TCBs to be detached to achieve the new limit. If there are tasks queued waiting for an X8 or X9 mode TCB and you increase MAXXPTCBS from its previously defined value, CICS attaches a new TCB to resume each queued task, up to the new limit.
