Notes

The parent Lock element uses the Mode element to determine the type of lock to create on an object. The value of this element is limited to one of the strings listed in the following table.

Value	Description
CommitShared	A shared lock is established on the specified object. Other shared locks can be created for the same object. A shared lock prevents transactions containing write operations, such as an Execute method call running an Alter command, on a specified object, from committing until the shared lock is removed. A shared lock does not prevent transactions containing read operations, such as a Discover method call or an Execute method call running a Statement command, from committing.
CommitExclusive	An exclusive lock is established on the specified object. Other shared or exclusive locks cannot be created for the same object. An exclusive lock prevents transactions containing either read or write operations on a specified object from committing until the exclusive lock is removed.
