OV_Transaction::Start()
OV_Transaction::Start_Trans()

string Start(

[in, optional] uint32 Timeout)

Parameters

Timeout

Timeout, in seconds, after which the write lock is released automatically (unless the timeout, set as a result of the StillAlive method, is still in progress). Optional parameter. Default value is 10 minutes.

Calling Convention

These methods can be called from a WMI class or instance object.

Description

Starts the transaction.

If the WMI write lock cannot be acquired from the AccessManager, the method waits until the WMI write lock is released.

The WMI write lock is released automatically as a result of the timeout when both timeouts (set with the Timeout parameter, as a result of the StillAlive method) end.

Theoretically, it is possible for the WMI write lock to be released even though the method that uses the transaction still has some work to do on WMI. For this reason, it is very important to use the StillAlive method.

Return Value

Id of the transaction started.

Extended Status Codes

None.
