IProfileService2::Initialize Method

  • Artikkeli

For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.

Use this method to establish a connection to the Commerce Server Profiles store and populate the schema cache with all the schemas from the specified catalog.

HRESULT IProfileService::Initialize(
  BSTR sConfigStore,
  BSTR sCatalog
);

Sub Initialize(
    sConfigStore As String,
    OptionalsCatalog As String
)

Parameters

  • sConfigStore
    [C++]

    [in] A BSTR that contains the connection string to the Profiles store.

    [Visual Basic]

    A String that contains the connection string to the Profiles store.

  • sCatalog
    [C++]

    [in, optional] A BSTR that identifies the catalog. If this is specified it must be "Profile Definitions".

    [Visual Basic]

    A String that identifies the catalog. If this is specified it must be "Profile Definitions".

Return Value

[C++]

This method returns an HRESULT indicating whether it completed successfully. See the Error Values section for more details.

[Visual Basic]

None.

Error Values

The Errors property stores the collection of errors encountered in the last Profiles resource operation. For more information, see IProfileService::get_Errors.

Remarks

The Initialize method creates the necessary internal parameters and schema cache for profile management. A ProfileService object must connect to only one Profiles store. Multiple instances of the ProfileService object must be created to access multiple stores.

The connection string for the Profiles store may be obtained through the SiteConfigReadOnly object, or through the Commerce Server Manager console from the s_ProfileServiceConnectionString property under the key "Commerce Server Manager\Global Resources\Profiles(ComputerName SiteName)".

The connection string is comprised of the following mandatory tokens:

  • Data Source and/or Database [mandatory]. This attribute allows applications to specify the name of the underlying SQL Server containing the Profiles database. At least one of these attributes must be specified. If both of these attributes are specified, the value of the Data Source attribute takes precedence.

  • Initial Catalog and/or [mandatory]. This attribute allows applications to specify the name of the Profiles database containing profile definitions. At least one of these attributes must be specified. If both of these attributes are specified, the value of the Initial Catalog attribute takes precedence.

  • User ID and/or UID [mandatory]. This attribute allows applications to specify the login name to connect to the Profiles database. At least one of these attributes must be specified. If both of these attributes are specified, the value of the User ID attribute takes precedence.

The following is a sample connection string containing these attributes:

   Data Source=servername;Initial Catalog=dbname;User ID=user

Spaces are not allowed around the delimiting semi-colon, and a semi-colon is not allowed in the names of any of the tokens.

Additionally, the following optional tokens are also supported by the Profiles resource:

  • Provider [optional]. Allows applications to specify the OLE DB provider to which the Profiles resource connects. This parameter exists for consistency with standard ADO connection strings. The default value and only acceptable value for this attribute is CSOLEDB.

  • Password or PWD [optional]. Allows applications to specify the password for the user specified by the User ID or UID attribute. The default value for this attribute is NULL.

  • PsObjectCacheSize [optional]. Allows applications to specify the size of the Profiles resource object cache. This cache stores ProfileObject objects instantiated by the CreateProfile and GetProfile methods. The default value for this attribute is 16384. Setting this value to 0 (zero) does not turn off caching. Instead, this value then reverts to the default value of 1024.

  • PsSchemaCacheSize [optional]. Allows applications to specify the size of the Profile resource definition (schema) cache in entries. The acceptable range of values is from one (1) to 1024. The default is 1024. This is not a hard limit. A warning will be posted to the eventlog if the number of entries exceeds 1024.

  • PsBackgroundThread [optional]. Allows applications to control the creation of a background thread to periodically clean up entries from the Profiles resource object cache. The acceptable values for this parameter are zero (0) or one (1). Zero turns off the background thread, one turns it on. By default, the background thread is on.

  • PsObjectAgeoutPeriod [optional]. Allows applications to specify the age-out period for the Profiles resource cache entries. The age-out period is the amount of time an unreferenced object can remain in the cache without being discarded. The default value for this attribute is five minutes.

  • Integrated Security [optional]. Allows applications to connect to the Profile Service using integrated windows authentication. The value for this token should be SSPI. When this token is specified the values for User ID/UID and Password/PWD tokens are ignored.

  • Site Name [optional]. Allows applications to specify the site name under which the Profile Service counters should be logged. If no value is specified the performance counters are logged under Anonymous.

  • Connection_Retry [optional]. Allows the applications to specify the number of retry attempts if the connection to the Profile definition store is lost due to a communication failure. The default value for this attribute is 10.

  • Connection_Retry_Delay [optional]. Allows the applications to specify the delay in seconds between retry attempts if the connection to the Profile definition store is lost due to a communication failure. The default value for this attribute is 30.

  • PublicKey [optional]. This token allows the applications to specify the public key if any of the profiles defined use asymmetric encryption. The value for the token should be a hexadecimal string representation of the Public Key. The value should not be enclosed in quotes.

  • KeyIndex [optional]. This token is mandatory if the PublicKey is specified. Since Public and Privtate keys come in pairs, this token allows the applications to specify which PrivateKey token value corresponds to the PublicKey token.

  • PrivateKey1 [optional]. This token allows the applications to specify the Private key for decryption. The value for this token should be specified if the current key index is 1 and should correspond to the PublicKey. The value for the token should be a hexadecimal string representation of the Private Key. The value should not be enclosed in quotes.

  • PrivateKey2 [optional]. This token allows the applications to specify the Private key for decryption. The value for this token should be specified if the current key index is 1 and should correspond to the PublicKey. The value for the token should be a hexadecimal string representation of the Private Key. The value should not be enclosed in quotes.

    Note

    The Initial Catalog in the connection string is the database containing the Profiles store.

    Note

    The sCatalog parameter in the Initialize method is the catalog containing the profile schema definitions, which is "Profile Definitions".

The background thread removes the aged-out objects periodically from the cache. This means that the object may remain in the cache beyond the object age-out period. In this case, the object will be removed from the cache when the background thread processing resumes.

Example

' Connect using an explicit connection string.
' oProfileService is a Server ProfileService object.

oProfileService.Initialize "Provider=CSOLEDB;Data Source=MyServer;" _
 & "Initial Catalog=Retail_commerce;Integrated Security='SSPI';" _
 & "PsSchemaCacheSize=128;PsObjectAgeoutPeriod=8", "Profile Definitions"

' Connect through the SiteConfigReadOnly object.
' sConn is a String.
' oSCRO is an initialized SiteConfigReadOnly object.

sConn = oSCRO.Fields("Profiles(ComputerName SiteName").Value _
 .Fields("s_ProfileServiceConnectionString").Value & "SCHCACHE=128"
oProfileService.Initialize sConn, "Profile Definitions"
