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. This functionality should never be used for any other purpose than stress testing. The DbEnv::set_pageyield interface affects the entire application, not a single database or database environment. 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 The DbEnv::set_pageyield method may fail and throw an exception or return a non-zero error for the following conditions: EINVAL An invalid flag value or parameter was specified. The DbEnv::set_pageyield method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv::set_pageyield method may fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
