When a server goes down and then comes back online, Process Server recovers and resumes active processes automatically. However, for a pending invoke activity, you may want to suspend the process to inspect whether the service partially or fully completed its operation. In the Process Console, you may wish to manually restart the suspended process using the input message data.
If a server terminates unexpectedly, processes may be executing. Because they may not have saved process state to the database, the server must execute parts of a process to bring it back to the state it was in. Journal entries record the steps between process state being saved, and they are re-played during recovery. When a failure occurs, another node in the cluster may attempt to recover the process after a designated grace period.
You can add a policy assertion to the endpoint reference for the partner role of the partner link associated with an invoke activity to specify whether to suspend the process if that invoke activity is in a pending (executing) state during process recovery.
Select a setting for suspend process:
. If this optional attribute is not present, then invoke recovery handling is specified by the Suspend process on invoke recovery setting on the Engine Properties tab of the Engine Configuration page.
. Suspend a process when a pending invoke is found during process recovery
. Do not suspend a process when a pending invoke is found during process recovery.
