Log shipping data replication with parallel log writing and log shipping at the primary site

A log-shipping data replication system, comprising:

• a primary server;
• a standby server coupled to the primary server;
• wherein the primary server stores a first set of executable instructions for:
• concurrently flushing a first log data at the primary server and transmitting the first log data from the primary server to the standby server;
• and
• transmitting at least one buffer flush boundary indication to the standby server, the at least one buffer flush boundary indication indicating a flushing status of the first log data at the primary server;
• and
• wherein the standby server stores a second set of executable instructions for processing the first log data at the standby server as a function of at least one of the standby server receiving the first log data and the standby server receiving the at least one buffer flush boundary indication.

A log-shipping data replication system, comprising:

• a primary server;
• a standby server connected to the primary server;
• and
• wherein the primary server includes
• means for concurrently flushing a log data at the primary server and transmitting the first log data from the primary server to the standby server, and
• means for transmitting at least one buffer flush boundary indication to the standby server, the at least one buffer flush boundary indication indicating a flushing status of the log data at the primary server;
• and
• wherein the standby server includes means for processing the log data at the standby server as a function of at least one of the standby server receiving the log data and the standby server receiving the at least one buffer flush boundary indication.
