# Get-OrchDBSchema
Gets SQL scripts to create or maintain the database schema for the Citrix Orchestration Service.
Syntax
Get-OrchDBSchema [-DatabaseName <String>] [-ServiceGroupName <String>] [-ScriptType <ScriptTypes>] [-LocalDatabase] [-Sid <String>] [-AdminAddress <String>] [<CommonParameters>]
Detailed Description
Gets SQL scripts that can be used to create a new Orchestration Service database schema, add a new Orchestration Service to an existing site, remove a Orchestration Service from a site, or create a database server logon for a Orchestration Service. If no Sid parameter is provided, the scripts obtained relate to the currently selected Orchestration Service instance, otherwise the scripts relate to Orchestration 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 Orchestration 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:
o Creation of service schema
o Creation of database server logon
o Creation of database user
o Addition of database user to Orchestration Service roles
If ScriptType is Instance, the returned script contains:
o Creation of database server logon
o Creation of database user
o Addition of database user to Orchestration Service roles
If ScriptType is Evict, the returned script contains:
o Removal of Orchestration Service instance from database
o Removal of database user
If ScriptType is Login, the returned script contains:
o 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.

Parameters
| Name | Description | Required? | Pipeline Input | Default Value |
|---|---|---|---|---|
| DatabaseName | Specifies the name of the database into which the new Orchestration 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. | false | false | |
| ServiceGroupName | The name of the service group to be used when creating the Citrix Orchestration Service database schema. The service group is the collection of all Orchestration Services that share the same database and are considered equal (i.e. any service in the same service group can be used interchangeably). | false | false | |
| ScriptType | Specifies the type of database script returned. Available script types are: -- FullDatabase Creates a database schema for the Citrix Orchestration 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 Orchestration 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 Orchestration 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 Orchestration 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. |
false | 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 Orchestration services. If this parameter is specified inappropriately, the service instance will not be able to connect to the database. | false | false | |
| Sid | Specifies the SID of the controller on which the Orchestration Service instance to remove from the database is running (only valid for a script type of Evict). | false | true (ByValue) | None |
| AdminAddress | Specifies the address of a XenDesktop controller the PowerShell snap-in will connect to. You can provide this as a host name or an IP address. | false | false | Localhost. Once a value is provided by any cmdlet, this value becomes the default. |
Input Type
None
You cannot pipe input into this cmdlet.
Return Values
System.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
-----------
GetSchemasFailed
The database schema could not be found.
ActiveDirectoryAccountResolutionFailed
The specified Active Directory account or Group could not be found.
DatabaseError
An error occurred in the service while attempting a database operation.
DatabaseNotConfigured
The operation could not be completed because the database for the service is not configured.
DataStoreException
An error occurred in the service while attempting a database operation - communication with the database failed for various reasons.
PermissionDenied
You do not have permission to execute this command.
AuthorizationError
There was a problem communicating with the Citrix Delegated Administration Service.
CommunicationError
There was a problem communicating with the remote service.
ExceptionThrown
An unexpected error occurred. For more details, see the Windows event logs on the controller or the XenDesktop logs.
Examples
EXAMPLE 1
C:\PS>Get-OrchDBSchema -DatabaseName MySiteDB -ServiceGroupName MyServiceGroup > C:\OrchestrationSchema.sql
Description
-----------
Gets a script to create the full database schema for the Citrix Orchestration Service and copies it to a file called "C:\OrchestrationSchema.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 Orchestration service schema.
EXAMPLE 2
C:\PS>Get-OrchDBSchema -DatabaseName MySiteDB -ScriptType Login > C:\OrchestrationLogins.sql
Description
-----------
Gets a script to create the appropriate database server logon for the Orchestration service. This can be used when configuring a mirror server for use.
