MAXXPTCBS

The MAXXPTCBS system initialization parameter specifies the maximum number, in the range 1 through 2000, of open X8 and X9 TCBs that can exist concurrently in the CICS region.

If you do not specify the MAXXPTCBS parameter the MXT value will be used to set the MAXXPTCBS parameter.

MAXXPTCBS=number: X8 and X9 are the TCBs that are used to provide support for C and C++ programs compiled with the XPLINK option.

For more information about open TCBs, see Open TCB management.
