DRAFT SP-4122 Application server cannot start with "Failed to create DesignObjectSchema" errors in High Availability environments

Symptoms

"Failed to create DesignObjectSchema" errors appear in application server logs. Even though the data server processes may start and run, the application server will fail to start.

Cause

This error can appear when the dataserver.password is inconsistent between all nodes. 

Action

Ensure that the data servers are able to communicate with one another. This can be done by reviewing the steps in the following documentation:
https://docs.appian.com/suite/help/19.4/Data_Server_Connection_Restrictions.html

Specifically, ensure that the dataserver.password property within the data-server-sec.properties file is consistent across all distributed nodes.

Affected Versions

  • This article applies to Appian 19.4 and later.
