The COORD_R_LOST2 reason code for mutually-aware environments allows a failback timer to be installed in custom coordination modules that do not handle any server failure action. When Adaptive Server restarts, the timer uses the cm_is_active API to handle the failback. cm_is_active checks if the coordination module is allowed to perform failback. See cm_is_active for more information.See the cml.c sample in $OPENSWITCH/sample/ on UNIX and %OPENSWITCH%\sample\ on Windows, under the cm_srvreq_hdl function under the case for COORD_R_LOST2 for the complete sample coding.
