Currently Running Processes with Mirroring

This might be a dumb question but I didn't see anything about it in the Mirroring documentation. Are processes that are currently running when the primary fails over to the secondary automatically switched over and continue processing? Or are they terminated and would need to be restarted on the secondary?

What kind of processes? Most user processes will need to be restarted on the other member. The mirror has some mechanisms to allow for, for example, productions to start automatically on failover, but for any given random process you probably need to handle that manually. You can use ZMIRROR.
