Description

Gets SQL scripts that can be used to create a new DelegatedAdmin Service database schema, add a new DelegatedAdmin Service to an existing site, remove a DelegatedAdmin Service from a site, or create a database server logon for a DelegatedAdmin Service. If no Sid parameter is provided, the scripts obtained relate to the currently selected DelegatedAdmin Service instance, otherwise the scripts relate to DelegatedAdmin Service instance running on the machine identified by the Sid provided. When obtaining the Evict script, a Sid parameter must be supplied. The current service instance is that on the local machine, or that explicitly specified by the last usage of the -AdminAddress parameter to a DelegatedAdmin SDK cmdlet. The service instance used to obtain the scripts does not need to be a member of a site or to have had its database connection configured. The database scripts support only Microsoft SQL Server, or SQL Server Express, and require Windows integrated authentication to be used. They can be run using SQL Server’s SQLCMD utility, or by copying the script into an SQL Server Management Studio (SSMS) query window and executing the query. If using SSMS, the query must be executed in ‘SMDCMD mode’. The ScriptType parameter determines which script is obtained. If ScriptType is not specified, or is FullDatabase or Database, the script contains:

  • Creation of service schema
  • Creation of database server logon
  • Creation of database user
  • Addition of database user to DelegatedAdmin Service roles

If ScriptType is Instance, the returned script contains:

  • Creation of database server logon
  • Creation of database user
  • Addition of database user to DelegatedAdmin Service roles

If ScriptType is Evict, the returned script contains:

  • Removal of DelegatedAdmin Service instance from database
  • Removal of database user

If ScriptType is Login, the returned script contains:

  • Creation of database server logon only

If the service uses two data stores they can exist in the same database. You do not need to configure a database before using this command.

Examples

EXAMPLE 1

Gets a script to create the full database schema for the Citrix DelegatedAdmin Service and copies it to a file called “C:\DelegatedAdminSchema.sql”

This script can be used to create the service schema in a database with name “MySiteDB”, which must already exist, and must not already contain a DelegatedAdmin service schema.

Get-AdminDBSchema -DatabaseName MySiteDB -ServiceGroupName  MyServiceGroup > C:\DelegatedAdminSchema.sql
<!--NeedCopy-->

EXAMPLE 2

Gets a script to create the appropriate database server logon for the DelegatedAdmin service. This can be used when configuring a mirror server for use.

Get-AdminDBSchema -DatabaseName MySiteDB -ScriptType Login > C:\DelegatedAdminLogins.sql
<!--NeedCopy-->

Parameters

-DatabaseName

Specifies the name of the database into which the new DelegatedAdmin service

schema is to be placed, or in which it already exists. The database

itself is not created by any of the script types; it must already

exist before the scripts are run.

Type: String
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-ServiceGroupName

The name of the service group to be used when creating the Citrix DelegatedAdmin Service database schema. The service group is the collection of all DelegatedAdmin Services that share the same database and are considered equal (i.e. any service in the same service group can be used interchangeably).

Type: String
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: True

-ScriptType

Specifies the type of database script returned. Available script types are:

  • FullDatabase

Creates a database schema for the Citrix DelegatedAdmin Service in a database

instance that does not already contain one. This is used when creating

a new site. DatabaseName and ServiceGroupName are required parameters

for this script type.

  • Database

Performs the same function as “FullDatabase”.

  • Instance

Adds a DelegatedAdmin Service instance to a database and so to the associated

site. Appropriate database server logons and users are created to

allow the service instance access to the required service schemas.

  • Evict

Removes a DelegatedAdmin Service instance from the database and so from the

site. All reference to the service instance is removed from the

database. DatabaseName and Sid are required parameters for this

script type.

  • Login

Adds a logon for the DelegatedAdmin Service instance to a database server.

This is specifically for use when configuring SQL Server mirroring

where the mirror server must have appropriate logons created for all

service instances in the site.

Type: ScriptTypes
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-LocalDatabase

Specifies whether the database script is to be used in a database

instance run on the same controller as other services in the service group.

Including this parameter ensures the script creates only the required permissions

for local services to access the database schema for DelegatedAdmin services.

If this parameter is specified inappropriately, the service instance will not be

able to connect to the database.

Type: SwitchParameter
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-Sid

Specifies the SID of the controller on which the DelegatedAdmin Service instance to remove from the database is running (only valid for a script type of Evict).

Type: String
Position: Named
Default value: None
Required: False
Accept pipeline input: True (ByValue)
Accept wildcard characters: False

-DatabaseRights

Specifies the right the database script should expect to be run under. Available rights are:

  • Mixed

Creates a database schema which uses all rights.

  • SysAdmin

Creates a database schema which does the minimum with the SysAdmin (sa) rights.

  • DbOwner

Creates a database schema which only needs Database Owner (dbo) rights.

This script expects to be used after the SysAdmin script has been run.

Type: String
Position: Named
Default value: Mixed
Required: False
Accept pipeline input: False
Accept wildcard characters: False

-AzureDatabase

Specifies that the generated schema must be compatible with Azure SQL limits, including not generating code for logins.

Type: SwitchParameter
Position: Named
Default value: None
Required: False
Accept pipeline input: False
Accept wildcard characters: False

CitrixCommonParameters

This cmdlet supports the common Citrix parameters: -AdminAddress, -AdminClientIP, -BearerToken, -TraceParent, -TraceState and -VirtualSiteId. For more information, see about_CitrixCommonParameters.

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.

Inputs

None

You cannot pipe input into this cmdlet.

Outputs

String

A string containing the required SQL script for application to a database.

Notes

The scripts returned support Microsoft SQL Server Express Edition, Microsoft SQL Server Standard Edition, and Microsoft SQL Server Enterprise Edition databases only, and are generated on the assumption that integrated authentication will be used.

If the ScriptType parameter is not included or set to ‘FullDatabase’ or ‘Database’, the full database script is returned, which will:

Create the database schema.

Create the user and the role (providing the schema does not already exist).

Create the logon (providing the schema does not already exist).

If the ScriptType parameter is set to ‘Instance’, the script will:

Create the user and the role (providing the schema does not already exist).

Create the logon (providing the schema does not already exist) and associate it with a user.

If the ScriptType parameter is set to ‘Login’, the script will:

Create the logon (providing the schema does not already exist) and associate it with a pre-existing user of the same name.

If the LocalDatabase parameter is included, the NetworkService account will be added to the list of accounts permitted to access the database. This is required only if the database is run on a controller.

If the command fails, the following errors can be returned.

Error Codes
