Roman Khachatryan commented on FLINK-23437:
-------------------------------------------
Thanks for reporting,
could you confirm that "oracle.net.ns.NetException: Got minus one from a read
call" is indeed caused by too many connections (maybe from db sessions
view/logs)?
And what are the the degree of parallelism (for sink), connection limit, and
the actual number of connections if you know it?

> Hi,
> I'm using JDBC XA connector to put data into Oracle database.
> I'm facing issue with too many concurrent connection to database.
> I changed this method to return XaFacadeImpl instead of XaFacadePoolingImpl
> and problem was solved.
> {code:java}
> static XaFacade fromXaDataSourceSupplier(
> Supplier<XADataSource> dataSourceSupplier, Integer timeoutSec) {
> return new XaFacadePoolingImpl(() -> new XaFacadeImpl(dataSourceSupplier,
> timeoutSec));
> }
> {code}
