使用Flink CDC、Debezium等CDC工具对Oracle进行基于log的实时数据同步时遇到异常ORA-16331: container is not open的解决方案。

1. 异常信息

异常信息通常如下：

at oracle.jdbc.driver.OracleStatement.executeInternal(OracleStatement.java:1823)
at oracle.jdbc.driver.OracleStatement.execute(OracleStatement.java:1778)
at oracle.jdbc.driver.OracleStatementWrapper.execute(OracleStatementWrapper.java:303)
at io.debezium.jdbc.JdbcConnection.executeWithoutCommitting(JdbcConnection.java:1446)
at io.debezium.connector.oracle.logminer.LogMinerStreamingChangeEventSource.startMiningSession(LogMinerStreamingChangeEventSource.java:678)
at io.debezium.connector.oracle.logminer.LogMinerStreamingChangeEventSource.execute(LogMinerStreamingChangeEventSource.java:245)

ORA-06512: at line 1

2. 解决方案

关键异常信息是，ORA-16331: container "ORACLE_TEST” is not open。
让DBA开启container ORACLE_TEST（替换为实际的container），然后重启CDC任务就可以修复了。
