DbEnv::set_lg_max

#include <db_cxx.h> int DbEnv::set_lg_max(u_int32_t lg_max); Description Set the maximum size of a single file in the log, in bytes. Because DbLsn file offsets are unsigned 4-byte values, the set value may not be larger than the maximum unsigned 4-byte value. By default, or if the value is set to 0, a size of 10MB is used. See Log File Limits for more information. The DbEnv::set_lg_max interface may only be used to configure Berkeley DB before the DbEnv::open interface is called. The DbEnv::set_lg_max 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 environment's log file size may also be set using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "set_lg_max", one or more whitespace characters, and the size in bytes. Configuration in the DB_CONFIG file silently overrules configuration done using the DbEnv::set_lg_max method. Errors EINVAL An invalid flag value or parameter was specified. Called after DbEnv::open was called. The specified log file size was too large.
