RESHASHTBL is a system parameter that defines the number of entries in the lock management resource name hash table. Each entry requires 4 bytes. A typical tuning goal is to have the RESHASHTBL parameter about four times larger than the total number of resources in use on the system. Managers of systems with memory constraints or systems that are not critically dependent on locking speed could set the table to a smaller size. RESHASHTBL has the AUTOGEN, FEEDBACK, and MAJOR attributes.
