It seems like your K engines are down. Can you start them, verify their status, and restart your application server?

@carloss:i see engines are running state. PFA for the same.

Check this previous Forum post: forum.appian.com/.../e-233772, especially Eduardo's comment

Two possibilities:
1. The KDB engines are not running
2. The KDB engines are running but the JBoss application server is not able to communicate with them.
If the latter is true, check if your user (the OS user account used for starting JBoss)has permissions on the directory in which Appian is installed.
There is yet another possibility , that I have faced but it's not likely.
Are you installing 16.3 ? If yes, then that another possibility maybe true.

Now it's working fine. Due to appian.sec file in the <APPIAN_HOME>/ear/suite.ear/conf directory was different between the two servers.Thank you so much carloss for help out this issue.

You're welcome!
