I have a little doubt, that from what I read in the service guard manual doesn't give me a clear idea,
When you create a service on a package.
when you put in the service the -r 2 restart option so it restarts 2 times the aplication in case it fails, what does the cluster exactly do?
Does it run a:
Custom stop and Custom start ?
just a Custom start ?
or only it runs again the service_cmd )
I imagine the first, but could you confirm?
Solved! Go to Solution.

Re: A service restart question
If the switching variables are then set correctly, the package will switch

Re: A service restart question

SolutionThis script keep on checking services and if any abruption or issue found with the state with service on current node it reads this paramters to restart service(s).
Depending on package switching parameters package gets shifted.
So in short, answer to your question is yes..it reads custom start..

Re: A service restart question
lets say we have:
service=/app/app.sh monitor
custom start=/app/app.sh start
custom stop=/app/app.sh stop
and service restarts=3
so if a kill the app the monitor exits and dies, then a restart happens, and it's going to run again the monitor:
/app/app.sh monitor
and because my app is down because I killed it the monitor will exit again, because its not starting the app doing a /app/app.sh start.
So in the monitor script you need to put the app start ?
any of you have and example monitor a script for a simple app ?
Thnx

Re: A service restart question
Answer is it it will restart package. Whole bunch of services that are started using customer defined run commands.
On other hand if you are defining any service startup in customer defined run commands area then service you specify in service_cmd will get restarted.
Hope this will clear your doubt...

Deepak

Re: A service restart question
A service restart simply tries to restart that monitoring IN CASE something prevented the monitor from verifying the required item(s) was actually available.
For example, the Oracle toolkit monitors to see whether specific processes are running, without which Oracle cannot work. If these fail, then the service fails, resulting in the package halting and being moved to another node.
