Sandboxed Solutions
In SharePoint Server 2007, solutions could be deployed at the farm level by farm administrators only. This practice was not conducive and posed a threat to the overall health of the farm as a fatal exception occurring in one application could bring the whole farm down.
Microsoft addressed this limitation by providing a new feature called the Sandboxed solutions or User solutions. Sandboxed solutions are only deployed to site collections and are only available to the site collection to which it was deployed. It can also be automatically disabled if its resource consumption crosses the defined threshold.
Sandboxed solutions sit in the solution library of each site collection. The solution store is located in the Galleries section of the site collection settings page.
To deploy a Sandbox Solution:
- Navigate to the site collection where the solution will be installed
- Click on the Site Actions menu and choose site settings
- Under Galleries section click on solutions
- Click the Solutions tab in the Ribbon and choose upload solution
- Upload your solution
- Click activate on the solutions tab.
