KB-1071 Checkengine script shows "1/2*" for one engine in a dual gateway installation

Symptoms

In a dual gateway installation, the following output is generated on executing checkengine.bat|sh:

 ENGINE_NAME 1/2* 

Cause

A running engine database process has been stopped on the secondary server.

Action

1. Run stop-suite.bat|sh on the primary server. This will stop the engines and create a new engine database file *.kdb.
2. On the secondary server, create a copy of stop-suite.bat|sh and name it as stop-suite-localhost.bat|sh and modify the following:
   1. Replace %APPIAN_ENGINE_NAME% admin %action% with %APPIAN_ENGINE_NAME% admin stop localhost
   2. This will stop the engines but won’t create a new database file *.kdb.
3. Run the newly created stop-suite-localhost.bat|sh script.
4. Run start-suite.bat|sh on the primary server followed by start-suite.bat|sh on the secondary server.
