Abstract
Data resources are shared by applications executing on a plurality of central electronic complexes. Each complex of a pair includes a resource lock manager (IRLM) which maintains the hold and wait locks for applications executing on the complex and selected wait locks for the other complex. Selective communication of lock request information is controlled by hash tables maintained in synchronization in each IRLM, which denote the interest of each complex in each hash class of data resources.
