質問 3：
A primary and standby database are enabled for HADR and are in peer state. The HADR_SYNCMODE configuration parameter is set to SYNC. An application connects to the primary database, issues a COMMIT and receives a successful return code in response. How were the log buffers for this unit of work processed?
A. The log buffers were written to the DB2 log files on the primary server, sent to the standby, and written to log files on the standby server. The return code was then sent to the application.
B. The log buffers were written to the DB2 log files on the primary server and received in the log buffers on the standby database. The return code was then sent to the application.
C. The log buffers were written to the DB2 log files on the primary server and sent to TCP/IP send buffer to be shipped to the standby server. The return code was then sent to the application.
D. The log buffers were written to the DB2 log files on the standby server and held in memory on the primary server. The return code was then sent to the application.
正解：A
