Connection Status 
You use the Connection Status screen to display the status of your enabled database servers.
A table lists your database servers. If a row is red and the No. of Available Connections column displays 0, the connection to your data source is not available. If the connection is successful, the No. of Available Connections column displays 1 or higher.
If a server has no available connections, a configuration, network, or communications problem is preventing SAP Manufacturing Integration and Intelligence (SAP MII) from connecting to the server.
Note
The Connection Status screen only shows information for Java Database Connectivity (JDBC) servers in which a connection pool is built. Most tag-based servers, such as Universal Data Servers (UDS), do not respond to a status check.
To display the connection status, do one of the following:
On the SAP MII administration menu, choose .
On the SAP MII administration menu, choose , and choose the Status tab page.
If you cannot establish a connection, do the following:
Confirm your settings for User, Password, and ServerURL on the Data Servers screen.
Verify that the Web server has the necessary security privileges to communicate with the data server.
