restartDB高可用验证

今天安装了一套restartDB，验证一下高可用。模拟监听意外挂掉：[root@restart ~]# ps -ef | grep LISTENER |grep -v grepgrid 2043 1 0 20:47 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/tnslsnr LISTENER -inherit[root@restart ~]# kill -9 2043[root@restart ~]# ps -ef | grep LISTENER |grep -v grepgrid 2551 1 1 21:01 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/tnslsnr LISTENER -inherit

接下来，干掉几个数据库重要进程试试：[root@restart ~]# ps -ef | grep ora_smon_restart | grep -v greporacle 2268 1 0 20:47 ? 00:00:00 ora_smon_restart[root@restart ~]# kill -9 2268[root@restart ~]# ps -ef | grep ora_smon_restart | grep -v grep[root@restart ~]# ps -ef | grep ora_smon_restart | grep -v greporacle 2788 1 0 21:23 ? 00:00:00 ora_smon_restart

[root@restart ~]# ps -ef | grep ora_ckpt_restart | grep -v greporacle    2786     1  0 21:23 ?        00:00:00 ora_ckpt_restart[root@restart ~]# kill -9 2786[root@restart ~]# ps -ef | grep ora_ckpt_restart | grep -v grep[root@restart ~]# ps -ef | grep ora_ckpt_restart | grep -v greporacle    2959     1  0 21:29 ?        00:00:00 ora_ckpt_restart

果然高可用。
