Roman Khachatryan commented on FLINK-21674:
-------------------------------------------
I'd suppose that the connection is closed on the network level.
But if maxRetries > 1 then JdbcBatchingOutputFormat will try to reconnect and
that could solve the problem (a proper solution would be keep-alive though).
Do you have maxRetries > 1? If not, could you try increasing it?

> 1.11 Flink System parallelism: 1 JDBC Driver: Oracle ojdbc10 Database: Oracle

> It will fail the application and restart from checkpoint. After restarting
> from checkpoint, the JDBC connection can be established correctly.
> The connection timeout can be configured by
> alter system set MAX_IDLE_TIME=1440; // Connection will get timeout after
> 1440 minutes.
> Such timeout parameter behavior change can be verified by SQL developer.
> However, Flink still got connection error after 5 minutes configuring this.
> I suspect this is some issues in reading some configuration problems from
> Flink side to establish to sucessful connection.
