Hi @chris_ahn 

If you have multi-instance configured, the first thing to check is port assignments - if you haven’t done this already.

One way to check this is to understand if Instance001 starts normally, but Instance002 has trouble starting - does stopping Instance001 allow Instance002 to start?

If so, this indicates that tcp ports are bound to the Instance001 services and when Instance002 services attempt to start and bind to the same tcp port, it’s unable to bind and unable to start.

Please check and ensure that different ports have been specified for each instance.
