Katalyst: Safe Shutdown and Startup Procedure

Description

This article provides a Guidance for safely shutting down and restarting a KATALYST system.

Solution

Follow a graceful shutdown; do not perform forced power-offs to protect database integrity and service dependencies.

Shutdown order (reverse of startup):

1. Stop Katalyst D2D Web Server.
2. Stop ProcessorJS Server.
3. Stop ACD/Automation Server.
4. Stop ACD/Spectrus DB Server.
5. Stop Database Server.
6. Stop ACD/Arcus Server.

Startup order (after weekend):

1. Start ACD/Arcus Server.
2. Start Database Server.
3. Start ACD/Spectrus DB Server.
4. Start ACD/Automation Server.
5. Start ProcessorJS Server.
6. Start Katalyst D2D Web Server.
   
   Rationale:
   Protect database integrity by stopping databases gracefully to avoid uncommitted transaction loss and data/index corruption.
   Respect service dependencies to prevent connection failures, startup errors, and silent data issues.
