CAST Imaging System - Database - Neo4j - Error - Transaction logs are missing and recovery is not possible

When starting imaging, neo4j does not start and the debug.log shows the error:  'Transaction logs are missing and recovery is not possible'

This happens if something has happened to the transaction logs, such as they were moved or removed due to space issues.

However deleting/moving them is not permitted as per neo4j: https://neo4j.com/docs/operations-manual/current/configuration/transaction-logs

Since the transaction logs were missing,

1. Add below parameter to the neo4j.conf file which forces database to start without recovery in case of missing transaction logs.  

   dbms.recovery.fail_on_missing_files=false

2. After modifying with the parameter above, then restart the Neo4j Service
