Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of DB2 data sharing * **************************************************************** * PROBLEM DESCRIPTION: Enable Fast Log Apply (FLA) for single * * object GRECP recovery. * **************************************************************** * RECOMMENDATION: * **************************************************************** Currently, for the efficiency of FLA function during GRECP/LPL recovery of a single object, FLA function is disable. Unlike LPL recovery, GRECP recovery generally involves many pages. Therefore, GRECP recovery of a single object could benefit from list prefetch logic used during FLA function. So to improve the GRECP recovery performance, whenever the FLA storage is available, Data Manager (DM) log apply will always use FLA. Also, disable the serviceability trap code added in V9 to detect any internal abend during FLA function.
