Constant |
Description |
|---|---|
olapLockExtendedRead |
The object's properties can be read by other applications, but they cannot be changed or processed. This lock is used to prevent processing of dependent objects of an object that is being processed, such as dimensions that are shared by multiple cubes. Multiple olapLockExtendedRead locks can be applied to an object by multiple applications. However, no application can lock the object for processing or updating until all olapLockExtendedRead locks have been released. |
olapLockProcess |
The object's Process method can be initiated, and other applications can read the object's properties only until the lock is released. Only one olapLockProcess lock can be applied to an object at a time, and other applications can only apply olapLockRead locks while the olapLockProcess lock is in place. |
olapLockRead |
The properties of the object can be read from the repository and cannot be changed by another application until the lock is released. Other applications can issue olapLockRead, olapLockExtendedRead, and olapLockProcess locks, but not olapLockWrite locks, while the initial olapLockRead lock is in place. |
olapLockWrite |
The properties of the object can be modified in the repository using the Update method, and they are not available to other applications for any use until the lock is released. No other locks of any type can be applied to the object until the olapLockWrite lock is released. |
