Considerations for starting and ending OptiConnect
Here are the tips on balancing the number of prestart agent jobs and the time it takes to start and end the QSOC subsystem.
When you end OptiConnect, you also end any prestart agent jobs. The more agent jobs, the longer it takes to end the QSOC subsystem. Similarly, when you start OptiConnect, the larger the initial number of agent jobs that you specified, the longer it takes to start the subsystem.
Prestart agent jobs use resources when they are started or ended, so consider how many prestart agent jobs you need.
For example, if there are many short transactions as when retail stores process credit card authorizations, increasing the number of prestart jobs might be beneficial. Although increasing the number of prestart jobs increases the time it takes to start the QSOC subsystem, prestart jobs allow you to quickly process the credit card authorizations.
On the other hand, you might have longer or less numerous transactions, for example, when a teller at a bank signs on for the day. In this type of environment, you might want less prestart jobs and a shorter system startup.
Before ending the QSOC subsystem, vary off the *OPC controllers and the corresponding controllers on the other system. The ENDSBS QSOC command leaves the controllers in an unusable state that requires you to vary them off and then vary them on. If you vary off the controllers manually, less processing takes place when you end the subsystem.
