    #include <db.h>

    int
    DB_ENV->rep_set_limit(DB_ENV *env, u_int32_t gbytes, u_int32_t bytes);

    int
    DB_ENV->rep_get_limit(DB_ENV *dbenv, u_int32_t *gbytesp, u_int32_t *bytesp);

Description: DB_ENV->rep_set_limit

The DB_ENV->rep_set_limit method sets a byte-count limit on the amount of data that will be transmitted from a site in response to a single message processed by the DB_ENV->rep_process_message method. The limit is not a hard limit, and the record that exceeds the limit is the last record to be sent.

Record transmission throttling is turned on by default with a limit of 10MB.

If the values passed to the DB_ENV->rep_set_limit method are both zero, then the transmission limit is turned off.

The database environment's replication subsystem may also be configured using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "rep_set_limit", one or more whitespace characters, and the limit specified in two parts: the gigabytes and the bytes parameters. For example, "rep_set_limit 0 1048576" sets a 1 megabyte limit. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.

The DB_ENV->rep_set_limit method configures a database environment, not only operations performed using the specified DB_ENV handle.

The DB_ENV->rep_set_limit method may be called at any time during the life of the application.

The DB_ENV->rep_set_limit method returns a non-zero error value on failure and 0 on success.

Parameters
bytes

- The gbytes and bytes parameters specify the maximum number of bytes that will be sent in a single call to DB_ENV->rep_process_message method.

gbytes

- The gbytes and bytes parameters specify the maximum number of bytes that will be sent in a single call to DB_ENV->rep_process_message method.

Description: rep_get_limit

The DB_ENV->rep_get_limit method may be called at any time during the life of the application.

The DB_ENV->rep_get_limit method returns a non-zero error value on failure and 0 on success.

Parameters
bytesp

- The bytesp parameter references memory into which the additional bytes of memory in the current transmit limit is copied.

gbytesp

- The gbytesp parameter references memory into which the gigabytes of memory in the in the current transmit limit is copied.
