解決方案：

1）移除舊主機名相關的配置信息

[root@sztest ~]# cd /u01/app/grid/product/12.1.0/grid/crs/install/

[root@sztest install]# perl roothas.sh -deconfig -force

2）運行root腳本重新配置css服務

[root@sztest install]# cd /u01/app/grid/product/12.1.0/grid/

[root@sztest grid]# ./root.sh

Performing root user operation.



The following environment variables are set as:

ORACLE_OWNER= grid

3）配置asm、database、listener等組件信息

[grid@sztest ~]$ srvctl add asm

[grid@sztest ~]$ srvctl start asm



[oracle@sztest ~]$ srvctl add database -db orcl -oraclehome /u01/app/oracle/product/12.1.0/dbhome_1 -diskgroup "DATA,FRA"

從12.1.0.2開始，roothas.sh腳本替代了roothas.pl腳本。
