Cmdlet.TransactionAvailable Method ()
Updated: April 27, 2016
Applies To: Windows PowerShell
Determines whether the Start-Transaction cmdlet has been called and that there is a Windows PowerShell transaction available that the cmdlet can participate in. This method is introduced in Windows PowerShell 2.0.
Assembly: System.Management.Automation (in System.Management.Automation.dll)
Windows PowerShell transactions allow you to perform several actions as a group. If all the actions succeed you can accept the transaction. If any one of the actions fail, you can roll back the transaction.
Transactions are started only when the Start-Transaction cmdlet is run. When started, the Complete-Transaction cmdlet can be run to accept the actions of the cmdlets that participated in the transaction, or the Undo-Transaction cmdlet can be run to roll back the actions made by those cmdlets. Not all cmdlets that are run between when the Start-Transaction cmdlet and the Complete-Transaction cmdlet or the Undo-Transaction cmdlet are called, will participate in the transaction. Only those cmdlets that have their RequiresTx parameter set to true can participate in the transaction.
