Methods, computer readable media, and devices for identifying and preventing invalid memory access. A method may include defining a dynamic scope for an operation, receiving a request to allocate a portion of the range of shared memory, allocating a monotonically increasing portion of the range of shared memory such that a subsequent request to allocate memory is allocated a different portion of the range of shared memory, receiving a request to deallocate the allocated portion of the range of shared memory, deallocating the allocated portion of the range of shared memory by protecting the deallocated portion of the range of shared memory from any subsequent access, and in response to an access of the protected deallocated portion of the range of shared memory by one of the one or more threads or processes of the operation, trapping and terminating the one thread or process.

Identifying and preventing invalid memory access

A processor can produce a database catalog for a second version of a database management system of the database. The database catalog can store metadata related to definitions of objects or tables included in the second version of the database. A controller can be caused to be established in memory cells being used for the first version of the database. A copy of the database catalog for the second version of the database management system can be stored in the memory cells being used for the first version of the database. The controller, using the copy of the database catalog, can produce the second version of the database management system. The second version of the database management system can be caused to interact with data stored in a storage of the database. The storage can be included in the memory cells being used for the first version of the database.
