Typical failover
Figure 12-5 and Figure 12-6 show a typical MC/ServiceGuard failover. During a typical database node failover, MC/ServiceGuard will:
| Stop database services and release resources in a failed node |
| Unmount file systems |
| Deactivate volume groups |
| Activate volume groups in the standby node |
| Mount file systems |
| Assign package IP addresses to the LAN card on the standby node |
| Execute database startup and get the needed resources |
