1.6. Deleting or Removing a Web Application
At some point, you might no
longer need a particular Web application, or it might be replaced by
another one, and you will need to remove the existing Web application.
There are two options available for configuring a Web application to no
longer be available: you can either remove it or delete it.
Remove SharePoint From IIS Web Site
This action allows you to unextend the Web application and remove
SharePoint Services from using the Web application in IIS. The Web
application itself is not deleted and can still be used for
reprovisioning a new site collection at any time.
Delete Web Application
This option allows you to delete the Web application as well as the
databases associated with the Web application. This completely removes
all references to the Web application from your SharePoint farm,
including all the content the Web application was hosting.
Note:
Back up the content
databases before you delete a Web application in case you need to
recover any data stored in the databases at a later time.
1.7. General Settings
The General Settings option on the Web
Applications Ribbon lets you manage different aspects of the Web
application. You will find the following six options on the drop-down
list when you click the General Settings icon on the Ribbon. Each of these will be discussed in more detail in the following sections.
General Settings
Resource Throttling
Workflow
Outgoing E-mail
Mobile Account
SharePoint Designer
1.7.1. General Settings
Table 3
provides a list of explanations of the different general settings you
can configure for each Web application. These configurations are
applicable to all site collections accessed by the Web application.
Table 3. Web Application General Settings
| PROPERTY NAME | DESCRIPTION |
|---|
| Default Time Zone | All sites created on all Web
applications take the time zone from the farm’s global settings. With
this setting, you can change the default time zone for all sites created
on a specific Web application. |
| Default Quota Template | Allows
you to create and assign a specific database quota limit on the total
amount of content allowed to be stored for all site collections
associated with a Web application. Multiple quota templates can be created and used by different Web applications. |
| Person Name Actions and Presence Settings | When users browse a site, they can see details of the online
status of other users with instant messenger clients. If you prefer not
to make this information available, you can disable the option. By
default it is enabled for all Web applications. |
| Alerts | By
default, alerts are enabled that allow users to create their own alerts
on all sites they have access to on the specific Web application. You
can also limit the number of alerts a user can set up. By default, this
is set to 500 alerts per user. |
| RSS Settings | An RSS feed allows users to subscribe to lists and libraries in sites. To allow RSS feeds from lists and libraries, this option must be enabled. The default setting is enabled. |
| Blog API Settings | Enables
you to turn off the Blog API, or alternatively, if you choose to keep
it enabled, it can be set to allow user name and passwords to be sent
via the Blog API. |
| Browser File Handling | Indicates
whether security headers are included in documents displayed in Web
browsers. If you select the Permissive setting, no headers are added. If
you select the Strict setting, security headers are included in the
documents and security is improved by disallowing automatic execution of
Web content. |
| Web Page Security Validation | When
a session has been established to the sites, the session will cease
automatically if it has been idle for the specified amount of time,
which by default is 30 minutes. If a user tries to access the page after
it has been idle for the set amount of time, she will have to refresh
the page or re-establish the connection. |
| Send User Name and Password in E-mail | Allows
administrators to create or change a user’s details in the site and
have the new details e-mailed to the user. For additional security, you
could choose to disable this functionality. |
| Master Page Settings for Application _Layouts Pages | Indicates whether the pages in the _Layouts folder are allowed to reference site master pages. |
| Recycle Bin | The
Recycle Bin allows administrators in site and site collections to
restore deleted items from lists and libraries. You can specify how long
these items are stored in the Recycle Bin in their site and also how
long the items remain in the site collection’s Recycle Bin. The site
collection Recycle Bin is a second-level Recycle Bin that captures all
deleted content from site Recycle Bins. |
| Maximum Upload Size | Fixes
the size of content that users can upload to a site in any single
procedure. By default, this is 50 MB, and any file or group of files that a user tries to upload above this limit is rejected. |
1.7.2. Resource Throttling
SharePoint 2010 introduces the option to manage your SharePoint performance by specifying list view thresholds that control how much information can be involved in a database operation. These configuration settings will help optimize SharePoint by limiting the number of items that SharePoint handles during a single operation. Table 4 provides a list of settings and an explanation of these settings used to manage list resources.
Table 4. Web Application Resource Throttling Settings
| PROPERTY NAME | DESCRIPTION |
|---|
| List View Threshold | Specifies maximum number of items a database operation can involve at one time. The default setting is 5000. |
| Object Model Override | The default setting is to allow individuals with sufficient permissions to override the list view threshold programmatically. |
| List View Threshold for Auditors and Administrators | Specifies
maximum number of items a database operation can involve at one time
for users who have been granted sufficient permissions. The default
setting is 20000. |
| List View Lookup Threshold | Specifies
the number of Lookup, Person/Group, or workflow status fields that a
database query can involve in one operation. The default setting is 6. |
| Daily Time Window for Large Queries | Specifies
the time when queries that exceed the thresholds can be executed. This
setting usually designates hours outside of normal working hours. This
is disabled by default. |
| List Unique Permissions Threshold | Specifies the maximum number of unique permissions a list can have at one time. The default setting is 50000. |
| Backward-Compatible Event Handlers | By default, event handlers are off, so users cannot use an event handler operation for a document library. |
| HTTP Request Monitoring and Throttling | Controls whether the HTTP request throttling jobs are active or turned off. This option is enabled by default. |
| Change log | After
60 days, entries are deleted from the change log. You can change the
length of time in days or set it to never delete entries. |
