Get metadata about integration/s already running?

Summary

How can I find out if the current integration is already running with the same tracking information?

Content

Is there a way within an integration to gain information about other instances of the same integration running?

For example I have an OIC integration that cancels appointments.  The tracking on that integration is appointment ID.  It is possible that this integration could be called twice with the same appointment ID and I want to query and see if there are currently any processes in flight working with that record.

Is this possible at all? Thank you!
