Apis to create multi instances of a service ala sql 2005 instances

[John H]

Hi,
I have a windows nt service ( written in C++ ) lets call it
dowork.exe.
I would like to run another instance of it excatly like sql 2005 does
when you create another database instance.


Anyone know how to do this.?

Thanks very much

John

All the SQL server's exe runs for different Service Names, which
includes the instance name.

You can't have more than 1 copies of the exe running for a single
service. You can create any number of services (in a single exe) you
want but the names (of the service) must be different. So, in your exe
you could write code to register and run for 2 (or more) services. So,
this way same exe can be launched for different services....Just like
svchost.exe

If all you want is just 2 copies of exe and the instances has nothing to
offer as a service, you could directly launch your 2nd exe as a normal
child process from your service's process.

Thanks for the reply.
I need to create an arbitrary number but it will be triggered by a
user action e.g I want to provision a new service instance when a
customer is added , just like when a new sql instance is created in
sql 2005.
How does sql 2005 achieve this so I can use same logic/api's?

Thanks again.
