This argument enables ART application servers to reconnect to RM when requested.

-R MAX_TRANS_NUM

MAX_TRANS_NUM specifies the maximum number of transactions, no later than which ART for CICS server must reconnect to RM (after ART for CICS receives a reconnect request). Meaning, after receiving a reconnec request, an ART for CICS application server will reconnect to RM randomly (either during the next transaction in this case, or during any transaction no later than the one that MAX_TRANS_NUM specifies).

-R MAX_TRANS_NUM can appear anywhere in a server's CLOPT; however, if you omit MAX_TRANS_NUM (as MAX_TRANS_NUM is optional), -R must be the last argument of the CLOPT.
