Impossible to install more than one MID Server service as a daemon on a Linux host - "The ServiceNow MID Server daemon is already installed" - Known Error

Impossible to install more than one MID Server service as a daemon on a Linux host - "The ServiceNow MID Server daemon is already installed" Description When you try to register more than one mid server as a daemon on linux (redhat), this fails and returns the error:

"The ServiceNow MID Server daemon is already installed."

This is because the APP_NAME=mid is set in the installation script, which is a fixed name in all MID server installation folder. When trying to install more than one service with this name in the /etc/init.d directory, the system throws the error.

Steps to Reproduce

Run the below command for a second MID server on a Linux server:

sudo /agent/bin/mid.sh install

Workaround This is a limitation from the Tanuki java wrapper service provider. As a workaround you can stop all MID server service, then change the APP_NAME and APP_LONG_NAME value, on the mid.sh script, to make them unique for different MID servers:

# Application APP_NAME="mid" APP_LONG_NAME="ServiceNow MID Server"

However it is important to know that this is not recommended. The file gets overwritten every time the MID server is upgraded.
