Detailed Description

Specifies the database connection string for use by the currently selected Citrix Host Service instance.

The service records the connection string and attempts to contact the specified database. If the database cannot initially be contacted the service retries the connection at intervals until contact with the database is successfully established.

Is is not possible to set a new database connection string for the service if one is already recorded. The connection string must first be set to $null. This action causes the service to reset and return to its idle state, at which point a new connection string can be set.

When a database connection string is successfully set for the service, a status of OK is returned by the cmdlet. If the database connection string is set to $null, a DBUnconfigured status is returned.

A syntactically invalid 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 that on the local machine, or that explicitly specified by the last usage of the -AdminAddress parameter to a Host SDK cmdlet.

Parameters

Name Description Required? Pipeline Input Default Value
DBConnection Specifies the database connection string to be used by the Host Service. Passing in $null will clear any existing database connection configured. true false  
Force If present, allows the local administrator to set the connection string to null when there are problems contacting the database or other services. false false 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. false false  
BearerToken Specifies the bearer token assigned to the calling user false false  
TraceParent Specifies the trace parent assigned for internal diagnostic tracing use false false  
TraceState Specifies the trace state assigned for internal diagnostic tracing use false false  
VirtualSiteId Specifies the virtual site the PowerShell snap-in will connect to. false false  
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

Citrix.Fma.Sdk.Utilities.Service.Servicestatusinfo

The Set-HypDBConnection cmdlet returns an object describing the status of the Host Service together with extra diagnostics information. Possible values are:
– OK:
The Host Service instance is configured with a valid database and service schema. The service is operational.
– DBUnconfigured:
No database connection string is set for the Host Service instance.
– DBRejectedConnection:
The database rejected the logon attempt from the Host 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 Host 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 Host Service currently in use is newer than, and incompatible with, the version of the Host Service schema on the database. Upgrade the Host Service to a more recent version.
– DBOlderVersionThanService:
The version of the Host Service schema on the database is newer than, and incompatible with, the version of the Host 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 Host 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 Host 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 Host Service cannot be determined.

Notes

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