Chapter 8 Setting Deployment Options : Edit Service Instance Dialog

Edit Service Instance Dialog
Fields can be edited if this dialog is invoked from the Configuration Builder pane. If invoked from the Deployed Configuration pane, the fields are read only.
The following tabs are available:
General Tab
The General tab displays the following information:
Server Settings Tab
General
For file based domain, service instance deployed with Start on Boot option starts only if the Administrator server is running.
For data-based domain, the Administrator server does not need to be running; the database must be up.
Thread Count specifies the number of threads to use to execute process instances. The number of threads determines how many process instances can execute concurrently. Set the number of threads to a value that is appropriate for your operating system and physical machine configuration.
You should measure the available CPU and memory resources on your system under a typical processing load to determine if the default value of 8 threads is appropriate for your environment. For example, if engine throughput has reached a plateau, yet measurements show that CPU and memory are not fully utilized, increasing this value can have a positive effect on throughput. Typical numbers of worker threads range between 4 and 32. Specifying too low a value can cause higher memory use and lower engine throughput even though spare CPU resources exist. Specifying too high a value can cause CPU thrashing behavior, or an increase in latency caused by a large number of messages in the message queue.
Java
This pane is only available for Java applications.
NT Service
Graceful Shutdown Tab
This tab appears only if you have displayed this dialog box from a process. You can specify how a graceful shutdown occurs.
Kill Jobs Timeout
Specifies the maximum timeout in seconds after you click the Stop button that the process engine will wait for jobs to finish before shutting down the engine. A zero (0) value means 0 seconds, which effectively turns the graceful shutdown into an immediate shutdown.
Wait for Checkpoint
When selected, causes the process engine to wait for all jobs to finish after you click the Stop button (up to the maximum timeout) before shutting down the engine, rather than removing jobs at their next checkpoint.
