In MyEclipse8.5, deploy a project, run Tomcat server and get database shutdown error.
Solution: Since the SQL Server 2005 database defaults to disable the TCP/IP connection, this connection needs to be opened at this time.
Action: Open Microsoft SQL Server 2005--->Configuration Tools--->SQL Server Configuration Manager--->
MSSQLSERVER protocol, then right-click to start the TCP/IP protocol, and finally restart the service.
I did a VB project to connect to the database during the internship, and the database could not be opened. The reason is also the same.
