DbEnv::set_pageyield

#include <db_cxx.h> static int DbEnv::set_pageyield(int pageyield); Description Yield the processor whenever requesting a page from the cache. Setting pageyield to a non-zero value causes Berkeley DB to yield the processor any time a thread requests a page from the cache. The DbEnv::set_pageyield interface affects the entire application, not a single database or database environment. While the DbEnv::set_pageyield interface may be used to configure Berkeley DB at any time during the life of the application, it should normally be called before making any calls to the db_env_create or db_create methods. This functionality should never be used for any other purpose than stress testing. The DbEnv::set_pageyield interface may be used to configure Berkeley DB at any time during the life of the application. The DbEnv::set_pageyield method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success. Errors EINVAL An invalid flag value or parameter was specified.
