Multiple processes
Folks,
Please look at the following description:
We have a Start Script (START-PROCESSES script) that starts multiple processes :
A Process
B Process
C Process
D Process
We have implemented a manifest, and implemented the START / STOP / REFRESH methods, but when any of these process ( A / B / C etc.. ) fails, SMF stops and starts all processes.
Even though in our implementation every process is independent of other process.. A is independent of B, C is independent of B, C is independent of A. etc...
If A process crashes or cores, we don't want SMF to stop all processes and restart all processes, but should only start A process. Is this possible for us to acheive this ?
Since we don't want one process to effect the proper functioning of the other process. Because of this limitation we are unable to implement the SMF solution in our product
_Thanks Much

Using my completely limited knowledge of SMF internals, wouldn't it be easier to just create one SMF file as a template, and then create four separate SMF manifests, one for each process?

something like,
Blob must start before everything else and once blob is started then any of the four can be started in any order?
Like I said, I have limited knowledge of manifest files but IIRC you can set a dependency in their somewhere. So your manifest file would contain a dependency for BLOB and then would kick off the process. You could easily put this into a shell script and just loop through ps -ef until BLOB shows up and then continue on with the script.
Just a couple of silly suggestions.

Thanks for the replies, say for example I implement four manifests and import all these four manifests,
Then starting these processes will be like enabling these services will be some thing like :(
svcadm enable svc:/network/ProcessA
svcadm enable svc:/network/ProcessB
svcadm enable svc:/network/ProcessC
svcadm enable svc:/network/ProcessD
Which is in contrary to the START-PROCESSES script, which used to bring up all these processes.
Are there any other alternatives to this ?. or may be an RFE against SMF
