My library Knowledge Sources To Go is very popular, but it was intended mainly as a thematically grouped guide to standard sources and was provided by me as a PDF file. For certain topics, however, there is so much content that I can no longer include it in that document, as it cannot continue to grow forever.

For this reason, I have decided to handle such topics in individual community articles like this one instead.

What is the MID server?

 

The Management, Instrumentation, and Discovery Server is a Java application that runs as a Windows service or UNIX daemon on a server in your local network. The MID Server enables communication and the movement of data between a ServiceNow instance and external applications, data sources, and services. It is core to many successful implementations as it is used with several ServiceNow products such as Discovery, Service Mapping, Integration Hub, Orchestration, Cloud Provisioning and Governance, Event Management, and Operational Intelligence and can provides support for integrations with LDAP, Active Directory, and 3rd party integrations using SOAP or REST.

This is a great collection of troubleshooting resources! It's nice to have them all collected in one post. I have had so many issues with the auto-upgrading and with the amount of KB's written about it you can tell it's a common issue.

A tip that might help others with self inflicted wounds: if the MID server cannot initialize AMB, check that the default rest API ACL is not excluding the login used by the server from accessing endpoints.

Perhaps you could add the article about how to run multiple instances on Linux, which was not possible in New York, maybe Orlando either?
