229. What are Apex Governor Limits?
Governor limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception.
230. Difference between Sandbox and Development environment?
Sandbox
The salesforce.com Sandbox environment is an exact copy of your salesforce.com instance. You can copy your live instance to a sandbox environment (but you have to perform manually from sandbox to developer edition) where you can test any changes, implementations, AppExchangeapps or updates. It can also be your hands-on training environment without risking your live data.
You can either copy your configuration and data into a sandbox environment or just the configuration. It acts exactly like your live instance, but be careful if you have workflow rules or automations because they will work in the sandbox as well.
I know that this sounds wonderful and if you don’t have it, you are dying to know how to get it. The problem is the cost. If you are on Unlimited Edition, then cost is not a problem because it comes included. But for Enterprise, Professional or Group Editions, you have to pay… and the price is hefty; anywhere between 25k-50k per year. For a lot of companies, that is more than they are paying for their live salesforce.com instance. So how do you test salesforce.com without Sandbox? It is always suggested to develop application in sandbox instance then go for LIVE.
Developer Edition
Developer Edition was an edition created for development of integrations and apps, specifically for the AppExchange. It is also a great tool for testing/training in salesforce.com. What makes this a great tool is the fact that it is free. Anyone can get a Developer Edition of salesforce.com. It is a standard Enterprise Edition with very limited storage space. You cannot copy your configuration or data onto the Developer Edition, but you can customize it to match your instance’s look and feel. Once it is customized, you can use it for training, testing or anything else you want. It takes a little bit of work, but you can make it act and feel just like your live instance. The work is well worth it for the free price.
231. How to schedule export or take the backup of salesforce?
Step by Step Instruction:
Click Setup >Data Management > Data Export > Schedule Export.
Select the desired encoding for your export file. Leaving the default is fine.
Check the Include in export checkbox if you want to include attachments in the export (optional)
Leave the default Replace carriage returns with spaces if you want your export files to have spaces instead of carriage returns.
Select Weekly as the frequency for the exports.
Choose start and end dates. Set the end date to sometime in the distant future such as 20 years from the begin date.
Set the time of day for your scheduled export. The export is put in a job queue and the exact time of the export will depend on the amount of activity in the queue.
You can select the types of data to include in your export. It is best to include all data in your export file. This will make sure all your organizations data is exported.
Click Save.
Points to Remember:
Formula and roll-up summary fields are never included in exports.
Articles are not included from exports.
The export notification email is sent to the email address on file for the user who created the scheduled export. There is no way to indicate another email address. If as an Administrator you want the email to go to another person, have them grant you login access, login as them and schedule the data export.
Important:
Scheduled backup exports of your data are limited to weekly exports.
You have 48 hours from the time you are notified the backup is available to download the backup file.
The email notification for backups goes to the email address in Salesforce of the person logged in who schedules the backup
232. Do governor limits apply to sandbox instances?
Governor limits do apply to all Salesforce instances (trial, developer, and production or sandbox environments). However code coverage and successful execution of test classes is only enforced when deploying to a production environment.
233. What actions can be performed using Workflows?
Following workflow actions can be performed in a workflow:
1. Email Alert:
Email alerts are workflow and approval actions that are generated using an email template by a workflow rule or approval process and sent to designated recipients, either Salesforce users or others. Workflow alerts can be sent to any user or contact, as long as they have a valid email address.
2. Field Update:
Field updates are workflow and approval actions that specify the field you want updated and the new value for it. Depending on the type of field, you can choose to apply a specific value, make the value blank, or calculate a value based on a formula you create.
3. Task:
Assigns a task to a user you specify. You can specify the Subject, Status, Priority, and Due Date of the task. Tasks are workflow and approval actions that are triggered by workflow rules or approval processes.
4. Outbound Message:
An outbound message is a workflow, approval, or milestone action that sends the information you specify to an endpoint you designate, such as an external service. An outbound message sends the data in the specified fields in the form of a SOAP message to the endpoint.
234. How to delete an apex class or trigger in salesforce.com production environment?
In salesforce.com production environment the Del option is not displayed for classes & triggers. Follow the below steps to delete file in production:
• Go to your sandbox (where you do your Trigger/Class development) and delete the Trigger/Class from there. Also delete the Test Methods that test the Class/Trigger.
• Go to Eclipse and do a Refresh from Server. This will make the files disappear within Eclipse.
• Then deploy to Production, ticking Delete next to the files in your Deployment Plan. (For safety, always Deselect All when deploying, then sort by Type. Only then tick which files to deploy, since choosing the wrong ones could cripple Production.)
235. What are governor limits in Salesforce.com?
Governor limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception that cannot be handled thereby terminating the request.

Profile:
Profiles are set of permissions and setting which determines the objects, the fields of the object, tabs & apps the user can access. It also determines the page layout & record type accessible to the user. Profile is a required field while user creation.

Groups are set of users. They can contain individual users, other groups, the users in a particular role or territory, or the users in a particular role or territory plus all of the users below that role or territory in the hierarchy.
There are two types of groups:
• Public groups: Only administrators can create public groups. They can be used by everyone in the organization.
• Personal groups: Each user can create groups for their personal use.
You can use groups in the following ways:
• To set up default sharing access via a sharing rule

Private Cloud: This also offers activities and functions "as a service" but is deployed over a company intranet or hosted datacenter. This is private product for a company or organization offering advance security.
Salesforce.com: Is a public cloud as it is hosted on salesforce.com data centers and data of more than one tenant resides on same servers.
243. What is the difference between custom controller and extension in salesforce?
Custom Controller: A custom controller is an Apex class that implements all of the logic for a page without leveraging a standard controller. Use custom controllers when you want your Visualforce page to run entirely in system mode, which does not enforce the permissions and field-level security of the current user.
Controller extension: A controller extension is an Apex class that extends the functionality of a standard or custom controller. Use controller extensions when:
• You want to leverage the built-in functionality of a standard controller but override one or more actions, such as edit, view, save, or delete.
• You want to add new actions.
• You want to build a Visualforce page that respects user permissions. Although a controller extension class executes in system mode, if a controller extension extends a standard controller, the logic from the standard controller does not execute in system mode. Instead, it executes in user mode, in which permissions, field-level security, and sharing rules of the current user apply.
A controller extension is any Apex class containing a constructor that takes a single argument of type ApexPages.StandardController or CustomControllerName, whereCustomControllerName is the name of a custom controller you want to extend.
Note: Although custom controllers and controller extension classes execute in system mode and thereby ignore user permissions and field-level security, you can choose whether they respect a user's organization-wide defaults, role hierarchy, and sharing rules by using the with sharing keywords in the class definition.
244. What are different kinds of reports?
1. Tabular: Tabular reports are the simplest and fastest way to look at data. Similar to a spreadsheet, they consist simply of an ordered set of fields in columns, with each matching record listed in a row. Tabular reports are best for creating lists of records or a list with a single grand total. They can't be used to create groups of data or charts, and can't be used in dashboards unless rows are limited. Examples include contact mailing lists and activity reports.
2. Summary: Summary reports are similar to tabular reports, but also allow users to group rows of data, view subtotals, and create charts. They can be used as the source report for dashboard components. Use this type for a report to show subtotals based on the value of a particular field or when you want to create a hierarchical list, such as all opportunities for your team, subtotaled by Stage and Owner. Summary reports with no groupings show as tabular reports on the report run page.
3. Matrix: Matrix reports are similar to summary reports but allow you to group and summarize data by both rows and columns. They can be used as the source report for dashboard components. Use this type for comparing related totals, especially if you have large amounts of data to summarize and you need to compare values in several different fields, or you want to look at data by date and by product, person, or geography. Matrix reports without at least one row and one column grouping show as summary reports on the report run page.
4. Joined: Joined reports let you create multiple report blocks that provide different views of your data. Each block acts like a “sub-report,” with its own fields, columns, sorting, and filtering. A joined report can even contain data from different report types.
245. What are different kinds of dashboard component?
1. Chart: Use a chart when you want to show data graphically.
2. Gauge: Use a gauge when you have a single value that you want to show within a range of custom values.
3. Metric: Use a metric when you have one key value to display.
• Enter metric labels directly on components by clicking the empty text field next to the grand total.
• Metric components placed directly above and below each other in a dashboard column are displayed together as a single component.
4. Table: Use a table to show a set of report data in column form.
5. Visualforce Page: Use a Visualforce page when you want to create a custom component or show information not available in another component type
6. Custom S-Control: Custom S-Controls can contain any type of content that you can display or run in a browser, for example, a Java applet, an ActiveX control, an Excel file, or a custom HTML Web form\
