Description
Tests whether the database specified in the given connection string is suitable for use by the currently selected Citrix AppLibrary Service instance.
The service attempts to contact the specified database and returns a status indicating whether the database is both contactable and usable. The test does not impact any currently established connection from the service instance to another database in any way. The tested connection string is not recorded.
Only use of Windows authentication within the connection string is supported; a connection string containing SQL authentication credentials is always rejected as invalid.
The current service instance is the one on the local machine, or the one most recently specified using the -AdminAddress parameter of a AppLibrary SDK cmdlet.
Examples
EXAMPLE 1
Tests whether the service instance could use a database called XDDB on an SQL Server Express database running on the machine called dbserver. Integrated Windows authentication is required.
Test-AppLibDBConnection "Server=dbserver\SQLEXPRESS;Database=XDDB;Trusted_Connection=True"
<!--NeedCopy-->
Parameters
-DBConnection
Specifies the database connection string to be tested by the currently selected Citrix AppLibrary Service instance.
| Type: | String |
| Position: | 1 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Credentials
If using SQL authentication, a PSCredential object containing the SQL credentials to be used. This can be created using the Get-Credential cmdlet. The credentials required are the SQL server login and its associated password. By default Windows authentication is used and no credentials need to be specified.
| Type: | PSCredential |
| Position: | 2 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Login
If using SQL authentication, the SQL server login to use. By default Windows authentication is used and no login needs to be specified.
| Type: | String |
| Position: | 2 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Password
If using SQL authentication, the SQL server password to use. By default Windows authentication is used and no password needs to be specified.
| Type: | SecureString |
| Position: | 3 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-LoggingId
Specifies the identifier of the high-level operation this cmdlet call forms a part of. Citrix Studio and Director typically create high-level operations. PowerShell scripts can also wrap a series of cmdlet calls in a high-level operation by way of the Start-LogHighLevelOperation and Stop-LogHighLevelOperation cmdlets.
| Type: | Guid |
| 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 can’t pipe objects to this cmdlet.
Outputs
Citrix.Fma.Sdk.Utilities.Service.ServiceStatusInfo
The Test-AppLibDBConnection cmdlet returns an object describing the status of the selected AppLibrary Service instance that would result if the connection string were used with the Set-AppLibDBConnection cmdlet together with extra diagnostics information for the specified connection string. The actual current status of the service is not changed. Possible diagnostic values are:
-
OK
The Set-AppLibDBConnection command would succeed if it were executed with the supplied connection string.
-
DBUnconfigured
No database connection string is set for the AppLibrary Service instance.
-
DBRejectedConnection
The database rejected the logon attempt from the AppLibrary Service. This may be because the service attempted to log on with invalid credentials or because a database has not been installed in the specified location.
-
InvalidDBConfigured
The specified database does not exist, is not visible to the AppLibrary Service instance, or the service’s schema within the database is invalid.
-
DBNotFound
The specified database could not be located with the configured connection string.
-
DBNewerVersionThanService
The version of the AppLibrary Service currently in use is newer than, and incompatible with, the version of the AppLibrary Service schema on the database. Upgrade the AppLibrary Service to a more recent version.
-
DBOlderVersionThanService
The version of the AppLibrary Service schema on the database is newer than, and incompatible with, the version of the AppLibrary Service currently in use. Upgrade the database schema to a more recent version.
-
DBVersionChangeInProgress
A database schema upgrade is in progress.
-
PendingFailure
Connectivity between the AppLibrary Service instance and the database has been lost. This may be a transitory network error, but may indicate a loss of connectivity that requires administrator intervention.
-
Failed
Connectivity between the AppLibrary Service instance and the database has been lost for an extended period of time, or has failed due to a configuration problem. The service instance cannot operate while its connection to the database is unavailable.
-
Unknown
The status of the AppLibrary Service cannot be determined.
Notes
If the command fails, the following errors can be returned:
-
InvalidDBConnectionString
The database connection string has an invalid format.
-
DatabaseConnectionDetailsAlreadyConfigured
There was already a database connection configured. After a configuration is set, it can only be set to $null.
-
PermissionDenied
You do not have permission to execute this command.
-
AuthorizationError
There was a problem communicating with the Citrix Delegated Administration Service.
-
ConfigurationLoggingError
The operation could not be performed because of a configuration logging error.
-
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 Citrix Virtual Apps and Desktops logs.
