Process Sentinels
The Process Sentinels (SWDIR\etc\procmgr) are responsible for controlling all the TIBCO iProcess Engine processes. If a node cluster architecture is used, then the Process Sentinels will exist on each server to manage the processes running on that server. This process operates in different ways depending on whether you are using a third party transaction processing monitor.
In a node cluster, the Process Sentinels have a master process on one of the servers, which manages and controls slave Process Sentinels on all the other servers in the node cluster.
The Process Sentinels control the safe startup and shutdown of processes on one or multiple servers i.e. making sure processes are started in the correct sequence.
The Process Sentinels can also monitor processes to check that they are running and can automatically restart them if they fail. It can also detect if SWDIR\logs\sw_error and SWDIR\logs\sw_warn files have been created and sends a work item to the administrator to inform them that these files have been created.
