Beyond aesthetics, what functional differences are there for running GNS3 as root versus running GNS3 as a non-root user?
Solution
Differences between root and non root installations :
During a root installation, subdirectories and files for the DB2® database product are created in a directory of the root user\'s choosing.
Unlike root users, non-root users cannot choose where DB2 database products are installed. Non-root installations are always placed in the $HOME/sqllibdirectory, where $HOME represents the non-root user\'s home directory. The layout of the subdirectories within the sqllib directory of a non-root is similar to that of a root installation.
For root installations, multiple instances can be created. Instance ownership is associated with the user ID under which the instance was created.
Non-root installations can have only one DB2 instance. The non-root installation directory contains all of the DB2 database product files and instance files with no soft links.
1. In Root installations User can select installation directory.
But in non root installations user can not select installation directory as DB2 database products are installed under the user\'s home directory.
2. In Root installations Multiple Number of DB2 instances are allowed, where as only one DB2 instances is allowed in non root installating proces.
3. Only Program files are deployed during installation in root installing, Instances must be created after installation.
but in non root Program files and instance files both are deployed.The DB2 database product is ready for use immediately after installation.
4. No Upgrade version and instances are available in root installation process, No need to uninstall the old version before installing the new version in non root. Install new version, and upgrade the instance, together.
