Hi, I have the message below starting the engines. Collabo

Old folder kdbs.

If all the engines are showing the FATAL status, that due to some other reason i.e., Some went wrong.(Start doing from the beginning with fresh installation)

If you are upgrading the your Appian, make sure you are following update guide and also you are using the same primary data source.

Suppose for example if you want to repair the  process execution engine kdbs, Please fine the below steps(Assume my Appian is in C:/ drive.)

1. Navigate to location where repair scripts available.
   • cd C:\appian\server\_scripts\tools
2. Repair the kdb file which is corrupted.(not working) .
   • repair C:\appian\server\process\exec\02\gw1\pe44.kdb
3. Navigate to the engine kdbs location.
   • cd C:\appian\server\process\exec\02\gw1\
4. Create new kdb file with the repaired kdb file.The new kdb file should be the highest number kdb file.(So the engine will start pointing the new kdb file)
   • copy pe44.kdb.repaired pe55.kdb

yes

We followed these two links to restore the server.

docs.appian.com/.../Quick_Start_Installation_Guide_for_Windows_and_JBoss.html
docs.appian.com/.../Upgrade_Guide.html

if the old instance of Appian is working fine, last one is good...Please verify below steps once..

1. Stop all engines for the currently running Appian suite.
2. Navigate to old instance(which you were using before update)
3. Start the engines and verify all engines are in OKAY status.

If any problem here, there is an issue with your old kdbs . we need fix it by following the steps I mentioned in my previous comments.

What do you are planning to do now? Fresh installation or Updation.

If fresh installation, Do it by following installation guide.

If Updation, follow below steps.

1. Switch back to old instance.
   • Stop Application server, search server and engines (Verify all processes are stopped by executing ps -ef , kill if any not stopped)
   • rename it to different name or delete the 'Appian' folder.
   • Rename your old instance to 'Appian'
2. Start Appian engines (now you are running old instance)
   • Make sure all engines are started with 'Okay' status(If any FATAL error follow steps I have mentioned earlier)
   • Run check point script and followed by clean up script
3. Start Search server
4. Start Application server, make sure suite.ear is successfully deployed and you are able to login
5. Stop the suite(Stop Application server, Search server and engines and Verify all processes are stopped)
6. Now either do the fresh installation of your required version
7. If you are updating follow the update guide.

We have to do either repair or rename only.

The problem is with your old instance. First you need fix that issue, then only you can do the update.So before going for fresh installation first fix the issue with old kdb files either by following my instruction in earlier comment or by raising support ticket.

I would suggest you contact Appian support, so you could get better help. Below are the contact details.

ramanjaneyulut,

I'd raised the ticket and mailed the support team.

We have checked in the task manager for engines which are inactive. It is showing the below error(screenshot attached):
