11. SANDBOX SOLUTIONS

12. Outline
•Challenges
•What are Sandbox Solutions?
•How do they work?
•What can I do them Sandbox Solutions?
•How can they be managed?

13. Challenges
•Dev, Admin Fight!
•Change production farm to Full 
•Memory Leaks
•Update web.config files
•Bad code that eats up farm resources
•Deploy everything to the GAC
•Admins have some control using CAS
•Difficult to implement
•Difficult to get right
•Largest cause of SharePoint Support cases

14. Overview of the Sandbox
•Allows a subset of the full capabilities
in the SharePoint API
•Secure – enforcing the sandbox
•Execute in a partially trusted environment
•Code executes in a special service process
•Subject to CAS
•Validation framework
• Provides way to do custom farm wide validation for the deployed packages
•Each solution is isolated to its site collection

17. Sandboxed Solution Lifecycle
Installation
• Upload into Solution Gallery
Activation
• Auto-activates features
Deactivation
• Inert operation, extended by developer
• Web Parts no longer execute
Deletion

18. Developing a
Sandbox Solution
Demo

19. Types of Sandboxed Solutions Sandboxed
Solutions Support
Event/Feature
• Sandboxed solutions offer Non-Visual Web Parts
Receivers
developers a subset of the
SharePoint API available fully
trusted solutions Feature Activation Custom Workflow
• Site collection and Events Actions
site scoped Features
• Many XML constructs available: Modules, Lists,
ContentTypes, etc.
InfoPath Forms Services List Definitions
• Client technologies to access
external data – JavaScript, Custom Actions Site Pages
Silverlight etc.
• Offloading resource usage and Site Columns Content Types
access handling to client

20. Sandbox Boundaries
•No SPSecurity
•No SPSite constructor
•Off-box connections, http, web services, etc
•ADO.net
•Enterprise features (Search, BCS, etc.)
•Threading
•P-Invoke
•IO
•Other sites

21. SANDBOX RESOURCE MONITORING

22. Load Balancing
•Sandboxed solutions can be run
in two modes
•Local Mode
• Execute code on the SharePoint WFE
• Low administration overhead
• Lower scalability
•Remote Mode
• Execution on back-end farm machine
• Via dedicated service applications
• Load balanced distribution of code
execution requests

23. Sandbox Solution Monitoring
How it works
•Site collection quotas specify the warning and hard limits for
number of resources that can be used per day
•Sum of resource measures are taken across solutions
deployed to site collection
•I.e., add up CPU Points for all solutions
•Max of resource utilization measures checked against site
collection quota to determine if it should be throttled/blocked

24. Monitored Resources
Resources Per Hard
Metric Name Description Units
Point Limit
AbnormalProcessTerminationCount Process gets abnormally terminated Count 1 1
CPUExecutionTime CPU exception time Seconds 200 60
CriticalExceptionCount Critical exception fired Number 10 3
Number of times solution
InvocationCount Count N/A N/A
has been invoked
Percentage Units of Overall
PercentProcessorTime Note: # of cores not factored in 85 100

ProcessCPUCycles CPU Cycles 1E+11 1E+11
ProcessHandleCount Windows Handles 10,000 5,000
(Hard Limit Only) Bytes written 1E+07
ProcessIOBytes Bytes 1E+08
to IO
Number of Threads
ProcessThreadCount Threads 10,000 200
in Overall Process
(Hard Limit Only)
ProcessVirtualBytes Bytes 1E+09 4E+09
Memory consumed
SharePointDatabaseQueryCount SharePoint DB Queries Invoked Number 400 100
Amount of time spent waiting
SharePointDatabaseQueryTime Seconds 20 60
for a query to be performed
UnhandledExceptionCount Unhanded Exceptions 50 3
We have to kill the process because it has
UnresponsiveprocessCount Number 2 1
become unresponsive
You can tweak these values to fit your need…

25. Sandbox Solution Monitoring
Case Study
• A solution has executed 40 SQL queries (via the SharePoint
OM)
• One point for SQL is 400 queries
• Means for SQL it’s consumed .1 resource points
• So the resource usage is for the day for that solution is .1
resource points + other counters

26. Sorting Uniform
Order Form
Demo

27. Key Takeaways
•You can build complex forms using InfoPath (Rapid Application
Development)
•Consider Sandbox Solutions first
•Safe
•Monitored
•Allow more manageable hosting scenarios
•Quotas are for all sandbox solutions in the site collection
• Be creative with your solution design (Use Silverlight + WCF)
•InfoPath + Sandboxed Solution  Better Together
