Description: Updates public access permissions, shared access policies and one or more user-defined name-value pairs for the specified container.  

Practical Usage

Useful for updating information or synchronizing data on a preset schedule or on demand.

Connection Parameters

Property

Type

Required

Default

Markup

Description

Connection

 

 

 

 

Indicates where user credentials and preferences should originate from. This is a design mode parameter used only during task construction and configuration, thus, comprises no markup. The available options are:

  • Host (default) - Specifies that user credentials and/or advanced preferences are configured individually for this activity. This option is normally chosen if only a single activity is required to complete an operation.

  • Session - Specifies that user credentials and/or advanced preferences are obtained from a pre-configured session created in a prior step with the use of the Azure Storage - Create session activity. This option is normally chosen if a combination of related activities are required to complete an operation. Linking several activities to a single session eliminates redundancy. Additionally, a single task supports construction and simultaneous execution of multiple sessions, improving efficiency.

Session

Yes if connection is session-based

AzureStorageSession1

SESSION="MyAzureSession"

The name of an existing session to associate this activity with. This parameter is active only if the Connection parameter is set to Session. The default session name is 'AzureStorageSession1'.

Account name

Text

Yes if connection is host-based

(Empty)

ACCOUNTNAME="myaccount"

The globally unique name of the Windows Azure storage account. This parameter is active only if the Connection parameter is set to Host.

  • HTTP - Hypertext Transfer Protocol

Timeout (seconds)

Number

No

90

TIMEOUT="180"

The timeout interval (in seconds) for requests made to the storage service. If the timeout elapses before a server response is returned, the operation times out and the service returns an error. The default timeout value is 90 seconds.

Blob endpoint URI

Text

No
