问题：
数据库启动报错：ORA-00119、ORA-00132等
环境：
DB:Oracle 11.2.0.4.0
OS:Redhat 6.5
问题现象：
启动数据库报错：
[grid@rac01 ~]$ srvctl start database -d cjcdb
PRCR-1079 : Failed to start resource ora.cjcdb.db CRS-5017: The resource action "ora.cjcdb.db start" encountered the following error: ORA-00119: invalid specification for system parameter REMOTE_LISTENER ORA-00132: syntax error or unresolved network name 'rac-scan.cjc.com:1521' . For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/rac02/agent/crsd/oraagent_oracle/oraagent_oracle.log". CRS-5017: The resource action "ora.cjcdb.db start" encountered the following error: ORA-00119: invalid specification for system parameter REMOTE_LISTENER ORA-00132: syntax error or unresolved network name 'rac-scan.cjc.com:1521' . For details refer to "(:CLSN00107:)" in "/u01/app/11.2.0/grid/log/rac01/agent/crsd/oraagent_oracle/oraagent_oracle.log". CRS-2674: Start of 'ora.cjcdb.db' on 'rac02' failed CRS-2674: Start of 'ora.cjcdb.db' on 'rac01' failed CRS-2632: There are no more servers to try to place resource 'ora.cjcdb.db' on that would satisfy its placement policy
其中remote_listener参数值为：rac-scan.cjc.com:1521
怀疑DNS解析SCAN失败
登录到rac01执行nslookup rac-scan.cjc.com
[root@rac01 bin]# nslookup rac-scan.cjc.com ;; connection timed out; trying next origin ;; connection timed out; no servers could be reached
查看resolv.conf配置信息被清空了，实际上每次服务器重启网卡resolv.conf配置都会被自动清空
[root@rac01 bin]# cat /etc/resolv.conf # Generated by NetworkManager nameserver 8.8.8.8
检查网卡配置文件里没有指定90的DNS，手动添加90DNS。
[root@rac02 bin]# cd /etc/sysconfig/network-scripts/ [root@rac02 network-scripts]# vim ifcfg-eth0 DNS1="192.168.31.90"
重新添加resolv.conf配置信息
[root@rac01 bin]# vim /etc/resolv.conf # Generated by NetworkManager nameserver 8.8.8.8 domain cjc.com nameserver 192.168.31.90 options rotate options timeout:2 options attempts:5
可以正常解析了
[root@rac01 bin]# nslookup rac-scan.cjc.com Server:192.168.31.90 Address:192.168.31.90#53 Name:rac-scan.cjc.com Address: 192.168.31.60 Name:rac-scan.cjc.com Address: 192.168.31.70 Name:rac-scan.cjc.com Address: 192.168.31.50
启动数据
[root@rac01 bin]# ./srvctl start instance -d cjcdb -i cjcdb1 [root@rac01 bin]# ./srvctl start instance -d cjcdb -i cjcdb2
检查实例状态
[root@rac01 bin]# ./srvctl status database -d cjcdb Instance cjcdb1 is running on node rac01 Instance cjcdb2 is running on node rac02
