Hi,I saw the following statements in a SQL DBA 2008 R2 and 2012 class text, and wondered why you cannot install all components in more that one instance? Does that mean you can’t have (or don’t want to have) more than one instance with the same component of SQL Server? Is it that you would have 1 database engine, and 1 copy of each component on a physical server, and then multiple instances of databases on it to utilize those components?Quote from text starts here:Additional instances of SQL Server require an instance name that you can use in conjunction with the servername and are known as named instances. If you want all your instances to be named instances, you do not need to install a default instance first. You cannot install all components of SQL Server in more than one instance. Toaccess a named instance, client applications use the address Server-Name\Instance-Name. For example, a namedinstance called Test on a Windows server called APPSERVER1 would be addressed as APPSERVER1\Test.There is no need to install SQL Server tools and utilities more than once on a server. You can use a singleinstallation of the tools to manage and configure all instances.Quote from text ends here:
