1. Create an instance of the SMS_ObjectLock WMI class

2. Get the method parameters object for the ReleaseLock method.

3. Assign the object path of the object you wish to unlock to the ObjectRelPath property.

4. Create an InvokeMethodOptions object instance. On the Context property, add a name/value pair. The name must be “MachineName” and the value must be name of the computer releasing the lock. For more information, see How to Acquire a Lock on a SEDO-Enabled Object

5. Call InvokeMethod on the SMS_ObjectLock instance.

6. InvokeMethod will return a SMS_ObjectLockRequest instance. Check the RequestState and LockState properties to get more information on the success or failure of the request.

The following example releases a lock on a SMS_ConfigurationItem object instance.

Copy Code

class Program { static void Main(string[] args) { ManagementScope scope = new ManagementScope(@"\siteservername\root\sms\site_ABC"); ReleaseLock(scope); } public static void ReleaseLock(ManagementScope scope) { ManagementPath path = new ManagementPath("SMS_ObjectLock"); ManagementClass objectLock = new ManagementClass(scope, path, null); ManagementBaseObject inParams = objectLock.GetMethodParameters("ReleaseLock"); inParams["ObjectRelPath"] = "SMS_ConfigurationItem.CI_ID=30"; InvokeMethodOptions options = new InvokeMethodOptions(); options.Context.Add("MachineName", "RequestingComputer"); ManagementBaseObject result = objectLock.InvokeMethod("ReleaseLock", inParams, options); } }

The SMS_ObjectLockRequest object contains the following properties:

RequestState

The table below displays the possible request state values. Request states Granted, GrantedAfterTimeout and GrantedLockWasOrphaned indicate a successful request and the user can then make and save modifications to the object. All other requests indicate error.

RequestStateID	RequestStateName
0	Unknown
2	Requested
3	RequestedCanceled
4	ResponseReceived
10	Granted
11	GrantedAfterTimeout
12	GrantedLockWasOrphaned
20	DeniedLockAlreadyAssigned
21	DeniedInvalidObjectVersion
22	DeniedLockNotFound
23	DeniedLockNotLocal
24	DeniedRequestTimedOut
50	Error
52	ErrorRequestNotFound
53	ErrorRequestTimedOut

LockState

The table below displays the possible lock state values.

LockStateID	LockStateName
0	Unassigned
1	Assigned
2	Requested
3	PendingAssignment
4	TimedOut
5	NotFound
