Replication
Question
An existing master-slave setup is currently using a delayed replication of one hour. The master has crashed and the slave must be "rolled forward" to provide all the latest data.
The SHOW SLAVE STATUS indicates these values:
- RELAY_LOG_FILE=hostname-relay-bin.00004
- RELAY_LOG_POS=1383 Which command set would make the slave current?
Options
- ASTOP SLAVE; SET GLOBAL master_delay=0; START SLAVE;
- BSTOP SLAVE; CHANGE MASTER TO RELAY_LOG_FILE = 'hostname-relay-bin.00004', RELAY_LOG_POS = 1383;
- CSTOP SLAVE; CHANGE MASTER TO MASTER_DELAY=0; START SLAVE;
- DSTOP SLAVE; CHANGE MASTER TO MASTER_DELAY=0; RELAY_LOG_FILE = 'hostname-relay-bin.00004', RELAY_LOG_POS = 1383;
