Appian Primary DS is working. Getting the following error: java.lang.

This confirms my theory. This is how you can fix the issue:

1. Make sure no k.exe is running (use Windows Task Manager to confirm)
2. Change the exension of server/process/exec/00/gw1/pe294.kdb to pe294.BAK
3. Change the exension of server/process/exec/01/gw1/pe294.kdb to pe294.BAK
4. Open a command prompt and run start-suite
5. Monitor the CPU and once it has gone down ~0% open the following command prompts (there will be a group of 32 minimized)

APP:PX*

wait until they all finish replaying transactions and show "Booted"

6. Once they all three show "Booted" you can run checkengine and confirm all engines are OKay.
7. Run stop-suite to do a proper shutdown
8. If this is successful you can now start the environment the normal way you do it
