ABSTRACT:
In response to an extension request to a shared memory file 104, shared file adding means 111 allocates an (additional) memory file 110; inter-host locking means 103 locks a hash table 106; hash table updating means 108 checks the number of data blocks in the (additional) shared memory file, and updates the hash table 106 to alter one of the data block addresses, out of those stored in entries in the hash table 106, pointing to the same data block in the shared buffer 104 so as to point to a data block in the (additional) shared memory file 110; and the added shared memory file 110 is thereby made available for shared use.
