YY Because Apex runs in a multitenant environment, the Apex runtime engine strictly enforces a number of — to ensure that runaway Apex does not monopolize shared resources. These—, or governors, track and enforce the statistics outlined in the following table. If some Apex code ever exceeds a —, the associated governor issues a runtime exception that cannot be handled. Governor — apply to an entire organization, as well as to specific namespaces. For example, if you install a managed package created by a salesforce.com ISV Partner fromForce.com AppExchange, the components in the package belong to a namespace unique from other components in your organization. Consequently, any Apex code in that package can issue up to 20 DML statements while executing. In addition, any Apex code that is native to your organization can also issue up to 150 DML statements, meaning more than 150 DML statements might execute during a single request if code from the managed package and your native organization both execute. Conversely, if you install a package from AppExchange that is not created by a salesforce.com ISV Partner, the code from that package does not have its own separate governor — count. Any resources it uses counts against the total for your organization. Cumulative resource messages and warning emails are also generated based on managed package namespaces as well. For more information on salesforce.com ISV Partner packages, see salesforce.com Partner Programs.

In a SOQL query with parent-child relationship sub-queries, each parent-child relationship counts as an additional query. These types of queries have a — of three times the number for top-level queries. The row counts from these relationship queries contribute to the row counts of the overall script execution. 2 Calls to the following methods count against the number of DML statements issued in a request:

Batch Apex heap size is 6 MB. Email services heap size is 18 MB.

4

Recursive Apex that does not fire any triggers with  
, 
, or 
statements exists in a single invocation, with a single stack. Conversely, recursive Apex that fires a trigger spawns the trigger in a new Apex invocation, separate from the invocation of the code that caused it to fire. Because spawning a new invocation of Apex is a more expensive operation than a recursive call in a single invocation, there are tighter restrictions on the stack depth of these types of recursive calls.

5

Salesforce also imposes a — on the number of 
 annotations: 200 method calls per full Salesforce user license per 24 hours. This is an organization-wide —. For example, suppose your organization has five full Salesforce user licenses and 100 Customer Portal User licenses. Your entire organization is — to only 1,000 method calls every 24 hours (5 * 200, not 105.) The HTTP request and response sizes are calculated as part of the total heap size. So regardless of this —, don't exceed the 3 MB total heap size. 7 Describes include the following methods and objects:

y

ChildRelationship objects

y

RecordTypeInfo objects

Õ

PicklistEntry objects

   calls

 apply individually to each

+
 . Use the  methods to determine the script execution — for your code while it is running. For example, you can use the 
.+,

 
 method to determine the number of DML statements that have already been called by your program, or the 
,
.+,

 
 method to determine the total number of DML statements available to your code in that context. For more efficient SOQL queries, particularly for queries inside of triggers, use selective (indexed) queries. Ñelective queries filter on primary keys, foreign keys, names, audit dates (such as, 
+  .
), or External ID fields. In large organizations, non-selective queries could be stopped at runtime in order to prevent very long running operation times. If you need them for your application, contact your salesforce.com representative.Note If you use a non-selective query in a trigger against an object that contains more than 100000 records an error is generated. You should include indexed fields in the 34(0(clause to avoid these exceptions. Static variable values are reset between API batches, but governor — are not. Do not use static variables to track state information on API batches, because Salesforce may break up a batch into smaller chunks than the batch size you specify. In addition to the execution governor —, Apex has the following —:

y

Maximum number of characters for a class: 1 million

y

Maximum number of characters for a trigger: 1 million

Õ

Maximum amount of code used by all Apex scripts in an organization: 2 MBNote

This — does not apply to certified managed packages installed from AppExchange, (that is, an app that has been marked AppExchange Certified). The code in those types of packages belong to a namespace unique from the code in your organization. For more information on AppExchange Certified packages, see theForce.comAppExchange online help.

This — also does not apply to any code included in a class defined with the -" 
annotation.

Õ

If a SOQL query runs more than 120 seconds, the request can be canceled by Salesforce.

Õ

Each Apex request is — to 10 minutes of execution.

Õ

A callout request to a given URL is — to a maximum of 20 simultaneous requests.

Õ

The maximum number of records that an event report returns for a user who is not a system administrator is 20,000, for system administrators, 100,000.

Õ

Each organization is allowed 10 synchronous concurrent events, each not lasting longer than 5 seconds. If additional requests are made while 10 requests are running, it is denied.

Õ

A user can have up to five query cursors open at a time. For example, if five cursors are open and a client application still logged in as the same user attempts to open a new one, the oldest of the five cursors is released.

Cursor — for different Force.com features are tracked separately. For example, you can have five Apex query cursors, five batch cursors, and five Visualforce cursors open at the same time.

Õ

In a single transaction, you can only reference 10 unique namespaces. For example, suppose you have an object that executes a class in a managed package when the object is updated. Then that class updates a second object, which in turn executes a different class in a different package. Even though the second package wasn't accessed directly by the first, because it occurs in the same transaction, it's included in the number of namespaces being accessed in a single transaction.

When defining email services, note the following:

y

An email service only processes messages it receives at one of its addresses.

y

Salesforce — the total number of messages that all email services combined, including On-Demand Email-to-Case, can process daily. Messages that exceed this — are bounced, discarded, or queued for processing the next day, depending on how you configure the failure response settings for each email service. Salesforce calculates the — by multiplying the number of user licenses by 1,000. For example, if you have ten licenses, your organization can process up to 10,000 email messages a day.

Õ

Email service addresses that you create in your sandbox cannot be copied to your production organization.

Õ

For each email service, you can tell Salesforce to send error email messages to a specified address instead of the sender's email address.

Õ

Email services rejects email messages and notifies the sender if the email (combined body text, body HTML and attachments) exceeds approximately 10 MB (varies depending on language and character set

For those that don¶t have time to weed through all 171 pages of the Spring µ10 Release Notes, I¶ve pulled out a few of my favorites for your viewing pleasure. I didn¶t hit all of the items in the release notes so make sure you pull up the the PDF and check out the goodies in detail.


—
Y
 
YY Y—  By far the most detailed new feature at 45 pages! You can now set up entitlement management so that your support reps can verify if your customers are eligible for support, create and maintain service contracts, specify service levels on a per customer basis and enforcement of service levels with time-dependent, automated processes. There is a TON of stuff around Entitlement Management including service contracts and milestones so definitely take a closer look!  YY—Y—  A quote is a record showing proposed prices for products and services created from an opportunity and its products. You can create a set of quotes to show different combinations of products, discounts, and quantities so customers can compare prices. Each opportunity can have multiple associated quotes, and any one of them can be synced with the opportunity. You can also create and email PDF quotes. 
YY Y—  Answers is the newest feature of the Community application that lets community members ask questions, post replies, and vote whether they like or dislike a reply. It looks somewhat similar to Ideas in such that you assign categories to communities and then enable Answers for the customer and partner portals. 
— Y


YY Y—  A ton on Knowledge enhancements including new API objects for articles, metadata components for data category groups, describe calls for data categories, SOQL and SOSL filter, field level security for articles, custom report types and access to articles in the partner portal. Y

 You can now include multiple levels in master-detail relationships. For example, in addition to defining a two-object master-detail relationship, such as Account²Expense Report, you can extend the relationship to subdetail records, such as Account²Expense Report²Expense Line Item. You can then perform operations across the master²detail²subdetail relationship. There are some caveats so check out the details.
