Abstract
Clearing share latches for databases, such as in-memory databases, is disclosed. In one embodiment, a computerized system includes a database having a number of sections, a client process and a core process. The client process is capable of asserting a share latch on a section of the database. The core process is capable of asserting an exclusive latch on a section of the database. The core process is further capable of clearing the share latch asserted by the client process, upon termination of the client process while the share latch is still asserted. Specific methods for such clearing, as well as latch logs, are also disclosed.
