How to purge/clean-up a Dev/Test environment?

We have had an on-going issue in our development environment that seems to have originated when it was not shutdown properly and KDBs got corrupt. We experience issues where incorrect sub processes are sometimes triggered, or the system says that a process model has not been found. When we try the same request again it works.

What we would like to do is purge all data in the environment, apart from the process models and user accounts. Can you please advise how we should go about doing this? We have tried deleting every single process through the Appian UI, but the problem remains. We also tried rebuilding analytics from scratch but that also doesn't help. Checkengine shows everything as normal.

thanks a lot.

Hi Eduardo. Sorry for the delay on this. The environment is still not behaving correctly (its not too bad apart from some process instances not starting as expected). I can now confirm one of the errors to you - when we try to start a process in debug mode (via process modeller) it sometimes doesn't start and we see an error "Process Model Not Found". after republishing and trying again it works.

We have most probably made things worse by trying to "fix" the issue ourselves by deleting and copying KDBs. What I did in my last attempt was to delete/clear all analytics KDBS and I also deleted the KDBS in 2 of the exec engines and copied the KDB from the other exec engine so all 3 engines referenced the same copy of the KDB.

Just to confirm that what we ideally want to do is start with a clean slate (i.e. purge all process data) and only retain our process models in this environment. Is there a way to do this? thanks
