Passivation and activation
Passivation and activation help with system performance and high availability. Passivation allows a requestor, service, or clipboard page to be saved into storage and reactivated later, helping to free up JVM memory.
Passivation
Passivation removes operator data from memory if an operator is not active.
Pega Platform uses database passivation by default, with filesystem passivation available as an alternate method.
To add a process to occur before passivation (for example, saving all call data and closing all tabs in a customer service application), use the pyPrePassivation activity. In order for this activity to be run as expected, you must implement the activity with the correct applies-to class (@baseclass).
Activation
If the operator continues working after a period of inactivity, the system retrieves their work from storage and puts it back into memory, referred to as activation.
To add a process to occur after activation (for example, reconnecting a user with a dropped call), use the pyPostActivation activity. In order for this activity to be run as expected, you must implement the activity with the correct applies-to class (@baseclass).
