今天尝试创建了一个RAC环境的PDB数据库，在本地执行alter pluggable database pdb01 open 成功了，但是使用上去了plus连接还是连接不上，提示错误如下：
C:\Users\Administrator>sqlplus system/[email protected]:1521/pdb01 SQL*Plus: Release 19.0.0.0.0 - Production on 星期日 11月 19 08:39:09 2023 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle. All rights reserved. ERROR: ORA-01109: database not open
依次检查配置：
1.手工启动pdb数据库
[oracle@mesdb01 ~]$ sqlplus / as sysdba

2.在Oracle用户下的tnsnames.ora文件添加了监听：
[oracle@mesdb01 ~]$ cd $ORACLE_HOME/network/admin
[oracle@mesdb01 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/product/19.0.0/db_1/network/admin/tnsnames.ora

(CONNECT_DATA =

(SERVICE_NAME = mesdb)
)
)
pdb01 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL= TCP)(HOST = mesdb-scan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pdb01)
)
)
[oracle@mesdb01 admin]$
3.重启grid用户下的监听
[oracle@mesdb01 admin]$ exit logout [root@mesdb01 ~]# su - grid Last login: Sun Nov 19 10:18:31 CST 2023 [grid@mesdb01 ~]$ lsnrctl stop LSNRCTL for Linux: Version 19.0.0.0.0 - Production on 19-NOV-2023 10:30:30 Copyright (c) 1991, 2022, Oracle.

发现问题依然存在，后来发现问题所在，下面这条指令需要在两个节点都执行一遍。但是我以为只需要在其中一个节点执行就可以了，所以只有有一个节点启动成功了，但我连接时候是连接到了另一个节点，因此提示失败。
检查如下：
节点一
[root@mesdb01 ~]# su - oracle

在两个节点都执行上述操作后OK!
