class ProcessModelSettings : EmbeddedObject

This class contains no methods.

The following table lists the properties exposed by the ProcessModelSettings class.

Name

Description

IdentityType

A read/write sint32 value that designates the account type under which an application pool will run. The possible values are listed later in the Remarks section.

IdleTimeout

A read/write datetime value that specifies the amount of time, in minutes, that a worker process should continue to run when no new requests are received and the worker process is not currently processing requests. The default is 20. After the specified time passes, the worker process notifies the World Wide Web Publishing Service (WWW service), which then terminates the worker process.

LoadUserProfile

A read/write boolean value. true if the Windows Process Activation Service (WAS) should load the user profile for a worker process; otherwise, false. The default is true. This setting is application pool specific.

ManualGroupMembership

A read/write boolean value. true if access rights to content directories or resources need to be manually configured through Access Control Lists (ACLs); otherwise, false. The default is false. A value of false means that the built-in IIS_IUSRS group membership will be used.

MaxProcesses

A read/write uint32 value that specifies the maximum number of worker processes in an application pool. The default is 1.

Password

A read/write string value that specifies the default password for the account that IIS uses as the identity for newly created out-of-process COM+ applications.

NoteNote:
The default values of the Password and UserName properties are set when IIS is installed. The values match the user name and password in the corresponding Microsoft Windows user account that is established at installation.

PingingEnabled

A read/write boolean value. true if the WWW service should monitor the health of a worker process by periodically verifying that it is running; otherwise, false. The PingingInterval property specifies the time delay between these verifications. The default is true.

PingInterval

A read/write datetime value that specifies the time delay, in seconds, between the health-monitoring requests that the WWW service sends to a worker process. The default is 30.

PingResponseTime

A read/write datetime value that specifies the amount of time, in seconds, that a worker process is given to respond to a health-monitoring request. The default is 90. After the time limit is exceeded, the WWW service terminates the worker process.

ShutdownTimeLimit

A read/write datetime value that specifies the amount of time, in seconds, that the WWW service should wait after a recycle threshold has been reached to terminate a worker process. The specified time enables a worker process to complete existing requests. The default is 90.

StartupTimeLimit

A read/write datetime value that specifies the amount of time, in seconds, that the WWW service should wait for a worker process to start and report its ready status to the WWW service. The default is 90.

UserName

A read/write string value that specifies the default user name for the account that IIS uses as the identity for newly created out-of-process COM+ applications.

NoteNote:
The default values of the UserName and Password properties are set when IIS is installed. The values match the user name and password in the corresponding Microsoft Windows user account that is established at installation.
Important noteImportant Note:
If you change the value of UserName, you must change it to a value that matches a valid Windows user account, and you must also change Password to the password for that Windows account.

This class contains no subclasses.
