Exploring MID Server

MID Server acts as the mediator between the network and the instance. MID Servers are used by other applications to connect to the instance.

MID Server overview

MID Servers are installed on hosts in a network by administrators, and the MID Servers are used by other applications to communicate with the instance or function within the network. For example, a MID Server configured with Discovery scans items in the network from that MID Server host. Once it collects the Discovery data, the MID Server securely transfers the data through the network firewall to the instance.

To set up a MID Server, the network must be prepared to access the instance and download site. There are several installation procedures depending on the host operating system and scale of deployment. Once installed, MID Servers can be configured with many capabilities and features to support applications.

After configuring your MID Server, you can add security by encrypting MID Server parameter values in the config.xml file. Encryption protects data that the MID Server returns to the ECC Queue. Other available security options include the authorization of SOAP requests, restricting access to the MID Server configuration file, and establishing secure socket layer (SSL) connections.

Upgrading the MID Server

The MID Server checks with the instance periodically to see if an upgrade is necessary. If the MID Server detects that a new version is available for upgrade, it downloads the installer from install.service-now.com and runs the package automatically. You can also elect to upgrade the MID Server manually. See MID Server upgrades for details.

Resolving MID Server issues

You can search the HI Knowledge Base for troubleshooting articles or monitor the MID Server status and track active issues from within the instance. Many articles on resolved MID Server issues have been collected on Servicenow MID Server Landing page [KB0960404]. For more information about common resolution procedures, see Resolving MID Server issues.
