#include <db_cxx.h>int DbEnv::set_mp_max_write(int maxwrite, int maxwrite_sleep);
int DbEnv::get_mp_max_write(int *maxwritep, int *maxwrite_sleepp);
The DbEnv::set_mp_max_write method limits the number of sequential write operations scheduled by the library when flushing dirty pages from the cache.
The DbEnv::set_mp_max_write 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.
The DbEnv::set_mp_max_write method may fail and throw DbException, encapsulating one of the following non-zero errors, or return one of the following non-zero errors:
The DbEnv::get_mp_max_write method returns the current maximum number of sequential write operations and microseconds to pause.
The DbEnv::get_mp_max_write method may be called at any time during the life of the application.
The DbEnv::get_mp_max_write 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.
