面对过去，不要迷离；面对未来，不必彷徨；活在今天，你只要把自己完全展示给别人看。这个问题是由于Oracle数据库的PDB（可移植数据库）容器没有打开导致的。你可以尝试以下方法解决这个问题：
- 确保PDB容器已经打开。你可以使用以下SQL命令来检查PDB容器的状态：
SELECT open_mode FROM v$pdbs WHERE name = 'PDB1';如果返回的状态不是
MOUNTED，你需要手动打开PDB容器。可以使用以下命令来打开PDB容器：ALTER PLUGGABLE DATABASE PDB1 MOUNT;- 在Flink CDC配置中，确保使用了正确的PDB名称。你可以在Flink CDC配置文件中设置
database.hostname、database.port和database.service-name等参数，以连接到正确的PDB。例如：
database.hostname: <your_host> database.port: <your_port> database.service-name: <your_pdb_service_name>- 如果问题仍然存在，尝试重启Oracle数据库实例，然后再次运行Flink CDC。

把PDB1开启，alter session set container=pdb1;
alter pluggable database pdb1 open;此回答来自钉群Flink CDC 社区。2024-01-18 11:03:50赞同 展开评论 打赏
