Abstract

The embodiments set forth techniques for managing database files for a plurality of users. In particular, a database server can perform the steps of (1) receiving, from a routing server, a request to perform an input/output (I/O) operation to a database file, (2) identifying a storage server through which the database file can be accessed, (3) interfacing with the storage server to obtain an exclusive lock on the database file, and (4) in response to determining that the exclusive lock is obtained: (i) writing, to metadata associated with the database file, information associated with the database server, and (ii) performing the I/O operation to the database file.
