I am creating a service using CreateService. The service will run again fine if it happens to crash and I would like to have Windows restart the service if it crashes. I know it
Used Deltanine's approach, but modified it a bit to be able to control each failure action:
SERVICE_FAILURE_ACTIONS servFailActions;
SC_ACTION failActions[3];
failActions[0].Type = SC_ACTION_RESTART; //Failure action: Restart Service
failActions[0].Delay = 120000; //number of seconds to wait before performing failure action, in milliseconds = 2minutes
failActions[1].Type = SC_ACTION_RESTART;
failActions[1].Delay = 120000;
failActions[2].Type = SC_ACTION_NONE;
failActions[2].Delay = 120000;
servFailActions.dwResetPeriod = 86400; // Reset Failures Counter, in Seconds = 1day
servFailActions.lpCommand = NULL; //Command to perform due to service failure, not used
servFailActions.lpRebootMsg = NULL; //Message during rebooting computer due to service failure, not used
servFailActions.cActions = 3; // Number of failure action to manage
servFailActions.lpsaActions = failActions;
ChangeServiceConfig2(sc_service, SERVICE_CONFIG_FAILURE_ACTIONS, &servFailActions); //Apply above settings
The answer above will give you the gist... but it wont compile.
try:
SERVICE_FAILURE_ACTIONS sfa;
SC_ACTION actions;
sfa.dwResetPeriod = INFINITE;
sfa.lpCommand = NULL;
sfa.lpRebootMsg = NULL;
sfa.cActions = 1;
sfa.lpsaActions = &actions;
sfa.lpsaActions[0].Type = SC_ACTION_RESTART;
sfa.lpsaActions[0].Delay = 5000;
ChangeServiceConfig2(hService, SERVICE_CONFIG_FAILURE_ACTIONS, &sfa)
You want to call ChangeServiceConfig2 after you've installed the service. Set the second parameter to SERVICE_CONFIG_FAILURE_ACTIONS
and pass in an instance of SERVICE_FAILURE_ACTIONS as the third parameter, something like this:
int numBytes = sizeof(SERVICE_FAILURE_ACTIONS) + sizeof(SC_ACTION);
std::vector<char> buffer(numBytes);
SERVICE_FAILURE_ACTIONS *sfa = reinterpret_cast<SERVICE_FAILURE_ACTIONS *>(&buffer[0]);
sfa.dwResetPeriod = INFINITE;
sfa.cActions = 1;
sfa.lpsaActions[0].Type = SC_ACTION_RESTART;
sfa.lpsaActions[0].Delay = 5000; // wait 5 seconds before restarting
ChangeServiceConfig2(hService, SERVICE_CONFIG_FAILURE_ACTIONS, sfa);
