2. 很明显ip别占用了，所以查询了下1521是否别占用了。[table=98%,rgb(208,206,206)]
[td=594] read-db1:~ # netstat -pan|grep 1521 tcp 0 0 10.1.88.143:1521 0.0.0.0:* LISTEN 56047/tnslsnr tcp 0 0 10.1.88.143:1521 10.1.88.141:9773 ESTABLISHED 56047/tnslsnr tcp 0 0 10.1.88.143:1521 10.1.88.141:42211 ESTABLISHED 56047/tnslsnr tcp 0 0 10.1.88.141:42211 10.1.88.143:1521 ESTABLISHED 8226/asm_pmon_+ASM1 tcp 0 0 10.1.88.141:9773 10.1.88.143:1521 ESTABLISHED

3. 现在客户已经无法连接到数据库了所以就直接杀掉占用进程了。[table=98%,rgb(208,206,206)]
[td=594] read-db1:~ # kill 56047 read-db1:~ # inetstat -pan|grep 1521 -bash: inetstat: command not found read-db1:~ # netstat -pan|grep 1521 tcp 0 0 10.1.88.143:1521 10.1.88.141:9773 TIME_WAIT - tcp 0 0 10.1.88.143:1521 10.1.88.141:42211 TIME_WAIT -

4. 确定杀掉后在尝试启动监听。
