1、修改 ip

mv ifcfg-bond0_101 ifcfg-bond0_101.bak

mv ifcfg-bond0.bak ifcfg-bond0

mv ifcfg-bond0:0.bak ifcfg-bond0:0

systemctl restart network

2、重启 udev 服务

systemctl restart systemd-udev-trigger.service

查看/dev/目录下有没有 asm-data1 磁盘生成

3、查看 ora.cssd 的服务是否启动，若没启动则先启动（root 用户）

/u01/app/12.1.0/grid/bin/crsctl status res -t

/u01/app/12.1.0/grid/bin/crsctl start resource ora.cssd -unsupported

4、关闭 asm 实例，并用修改好的 pfile 启动 asm 实例

sqlplus / as sysasm

shutdown immediate

startup nomount pfile='/u01/app/12.1.0/grid/dbs/init+ASM.ora';

create spfile='/u01/app/12.1.0/grid/dbs/spfile+ASM.ora' from

pfile='/u01/app/12.1.0/grid/dbs/init+ASM.ora';

shutdown immediate;

startup;

5、查看 DATA 是否挂载成功

sqlplus / as sysasm

select name,path from v$asm_disk where group_number=(select group_number from

v$asm_diskgroup where name='DATA');

6、更改/u01/app/oracle/product/12.1.0/dbhome_1/bin/oracle 权限

chown oracle:asmadmin /u01/app/oracle/product/12.1.0/dbhome_1/bin/oracle

chmod 6751 /u01/app/oracle/product/12.1.0/dbhome_1/bin/oracle

7、启动数据库并生成 spfile

startup nomount pfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/initgpp.ora';

create spfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/spfilegpp.ora' from

pfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/initgpp.ora';

shutdown immediate;

startup;

export ORACLE_SID=nbank

startup nomount

pfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/initnbank.ora';

create spfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/spfilegpp.ora' from

pfile='/u01/app/oracle/product/12.1.0/dbhome_1/dbs/initnbank.ora';

shutdown immediate;

startup;

8、生成密码文件

cd /u01/app/oracle/product/12.1.0/dbhome_1/dbs

orapwd file=orapwgpp password=oracle

orapwd file=orapwnabnk password=oracle

9、尝试远程连接，测试数据
