oracle19cPDB数据库连不上，提示ORA-01109: database not open，但是我以为只需要在其
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/oracle@192.168.1.25:1521/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 SQL*Plus: Release 19.0.0.0.0 - Production on Sun Nov 19 10:25:39 2023 Version 19.15.0.0.0 Copyright (c) 1982, 2022, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.15.0.0.0 SQL> show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 PDB01 MOUNTED SQL> alter pluggable database pdb01 open; Pluggable database altered. SQL> show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 PDB01 READ WRITE NO SQL>
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 # Generated by Oracle configuration tools. MESDB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = mesdb-scan)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (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 Last login: Sun Nov 19 10:25:31 CST 2023 on pts/0 [oracle@mesdb01 ~]$ sqlplus / as sysdba SQL*Plus: Release 19.0.0.0.0 - Production on Sun Nov 19 10:38:50 2023 Version 19.15.0.0.0 Copyright (c) 1982, 2022, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.15.0.0.0 SQL> show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 PDB01 READ WRITE NO SQL>
节点二：
[root@mesdb02 ~]# su - oracle Last login: Sun Nov 19 10:18:49 CST 2023 [oracle@mesdb02 ~]$ sqlplus / as sysdba SQL*Plus: Release 19.0.0.0.0 - Production on Sun Nov 19 10:36:48 2023 Version 19.15.0.0.0 Copyright (c) 1982, 2022, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.15.0.0.0 SQL> show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 PDB01 MOUNTED SQL>
在两个节点都执行上述操作后OK!
C:\Users\Administrator>sqlplus system/oracle@192.168.1.25:1521/pdb01 SQL*Plus: Release 19.0.0.0.0 - Production on 星期日 11月 19 10:30:42 2023 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle.

低级错误！
