4.转换步骤
4.1.准备工作
4.1.1.备份原数据库home信息
[oracle@raca1 ~]$ srvctl config database -home
ora19 /u01/app/oracle/product/19.0.0/db_1 19.0.0.0.0
4.1.2.备份原数据库配置信息
[oracle@raca1 ~]$ srvctl config database -db ora19
Database unique name: ora19
Database name: ora19
Oracle home: /u01/app/oracle/product/19.0.0/db_1
Oracle user: oracle
Spfile: +DATA/ORA19/PARAMETERFILE/spfile.270.1195478295
Password file:

Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Disk Groups: DATA
Services:
OSDBA group:
OSOPER group:
Database instance: ora19
4.1.3.备份原数据库服务信息
[oracle@raca1 ~]$ srvctl config service -db ora19
[oracle@raca1 ~]$ srvctl config listener -listener listener
Name: LISTENER
Type: Database Listener
Home: /u01/app/19.0.0/grid
End points: TCP:1521
Listener is enabled.
4.1.4.停库停监听
[oracle@raca1 ~]$ srvctl stop database -d ora19
[oracle@raca1 ~]$ ps -ef | grep ora_
oracle 35647 33054 0 14:03 pts/1 00:00:00 grep --color=auto ora_
[oracle@raca1 ~]$ su - grid
Last login: Tue Mar 11 12:50:33 CST 2025 on pts/2
[grid@raca1 ~]$ srvctl stop listener
4.1.5.卸载accfs文件系统（如果有）
4.1.6.取消standalone配置
[root@raca1 install]# pwd
/u01/app/19.0.0/grid/crs/install
[root@raca1 install]# ./roothas.sh -deconfig -force
Using configuration parameter file: /u01/app/19.0.0/grid/crs/install/crsconfig_params
The log of current session can be found at:

2025/03/11 14:06:02 CLSRSC-332: CRS resources for listeners are still configured
2025/03/11 14:07:23 CLSRSC-337: Successfully deconfigured Oracle Restart stack
4.1.7.更新inventory
[grid@raca1 bin]$ ./runInstaller -nowait -waitforcompletion -ignoreSysPrereqs -updateNodeList -silent -local CRS=false ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES=raca1" -doNotUpdateNodeLis
Starting Oracle Universal Installer...

You can find the log of this install session at:
/u01/app/oraInventory/logs/UpdateNodeList2025-03-11_02-12-30PM.log
'UpdateNodeList' was successful.
4.1.8.删除oratab记录
[root@raca1 ~]# sed -i '/ora19/d' /etc/oratab
4.1.9.同目录unlock home
[root@raca1 install]# pwd
/u01/app/19.0.0/grid/crs/install
[root@raca1 install]# ./roothas.sh -unlock -hahome /u01/app/19.0.0/grid

2025/03/11 14:18:42 CLSRSC-347: Successfully unlock /u01/app/19.0.0/grid
4.2.配置集群
4.2.1.gridSetup.sh
/u01/app/19.0.0/grid/install/response/grid_2025-03-12_09-39-17AM.rsp
[root@raca1 ~]# /u01/app/19.0.0/grid/root.sh
