文档课题：Oracle通过SQL语句查数据库服务器IP信息.

数据库：oracle 11.2.0.464位

系统：centos 7.964位

1、hosts文件

/etc/hosts文件内容如下：

#PublicIP (ens33)

192.168.133.210hisdb1

192.168.133.211hisdb2

#PrivateIP (ens37)

192.168.11.110hisdb1-priv

192.168.11.111hisdb2-priv

#VirtualIP (ens33)

192.168.133.212hisdb1-vip

192.168.133.213hisdb2-vip

#Scan IP(ens33)

192.168.133.214hisdb-scan

192.168.133.215hisdbdg

2、sql查询

查public ip及主机名.

SQL>col PUBLIC_IP for a20

SQL> colhostname for a15

SQL>select utl_inaddr.get_host_address PUBLIC_IP,utl_inaddr.get_host_name HOSTNAMEfrom dual;

PUBLIC_IP            HOSTNAME

-----------------------------------

192.168.133.210      hisdb1

dbms包查主机名和ip

SQL>set serveroutput on

SQL> begin

  2 dbms_output.put_line(utl_inaddr.get_host_name);

  3 dbms_output.put_line(utl_inaddr.get_host_address);

  4  end;

  5  /

hisdb1

192.168.133.210

PL/SQLprocedure successfully completed.

查rac publicip.

SQL>select * from v$configured_interconnects;

NAME            IP_ADDRESS       IS_ SOURCE

------------------------------- --- -------------------------------

ens37:1         169.254.207.21   NO

ens33           192.168.133.210  YES

ens33:1         192.168.133.214  YES

ens33:3         192.168.133.212  YES

SQL> col"RAC Device" for a15

SQL> selectindx          as "InterfaceIndex",

       inst_id       as "RAC Instance",

       pub_ksxpia    as "Public?",

       picked_ksxpia as "RAC Device",

       name_ksxpia   as "NIC Device",

       ip_ksxpia    as "IP Address"

  from x$ksxpia;

InterfaceIndex RAC Instance Public?    RACDevice      NIC Device      IP Address

--------------------------- ---------- --------------- --------------- ----------------

              0            1 N          GPnP            ens37:1         169.254.207.21

              1            1 Y          GPnP            ens33           192.168.133.210

              2            1 Y          GPnP            ens33:1         192.168.133.214

              3            1 Y          GPnP            ens33:3         192.168.133.212

注意：只显示本节点公网IP、VIP和ScanIP，无法查到私网 IP.

SingleDB查IP

SQL>col host for a15

SQL>col ip for a15

SQL>r

  1 select sys_context('USERENV', 'SERVER_HOST') as HOST,

  2        utl_inaddr.get_host_address(sys_context('USERENV', 'SERVER_HOST')) as IP

  3*  from dual

HOST            IP

hisdbdg         192.168.133.215

3、shell查询

查实例名.

[oracle@hisdb1~]$ ps -ef|grep ora_smon|grep -v grep

oracle     4080     1  0 16:45 ?        00:00:00 ora_smon_orcl1

[oracle@hisdb1~]$ ps -ef | grep ora_smon | grep -v grep| awk -F" " '{print $8}'|awk -F"_" '{print $3}'

orcl1

查IP.

[oracle@hisdb1 ~]$ grep -w $HOSTNAME /etc/hosts| grep -v vip | grep -vpriv| awk -F" " '{print $1}'

192.168.133.210

[oracle@hisdb1 ~]$ ping `hostname` -c 1
