Re: xml config can not be used in jdbs and user code simultaneously
First solution is bad idea because client could be closed by driver while user code still uses this client. 17 июля 2017 г. 12:49 PM пользователь "Vladimir Ozerov" < voze...@gridgain.com> написал: > I would say this is a usability issue, please file a ticket.

[jira] [Created] (IGNITE-5790) Xml config can not be used in jdbs and user code simultaneously
Mikhail Cherkasov created IGNITE-5790: - Summary: Xml config can not be used in jdbs and user code simultaneously Key: IGNITE-5790 URL: https://issues.apache.org/jira/browse/IGNITE-5790 Project: Ignite Issue Type: Bug Components: jdbc Affects Versions: 2.1 Reporter: Mikhail Cherkasov Assignee: Mikhail Cherkasov Fix For: 2.1 when user uses the same xml config for jdbc driver and for his own ignite instance there can be : java.sql.SQLException: Failed to start Ignite node. Caused by: class org.apache.ignite.IgniteCheckedException: Ignite instance with this name has already been started: CustomeIgniteName because JDBC creates separate ignite instance, while user already has one with the same name. Of course that can be easily workarounded, user can support two configs or create jdbc connect first and then use Ignition.getOrStart(). However it's inconvenient for user and should be treated as usability issue. I see 2 solutions: 1) jdbc driver should use Ignition.getOrStart() 2) jdbc driver should connection string as ignite name. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
Re: xml config can not be used in jdbs and user code simultaneously
I would say this is a usability issue, please file a ticket. But why one need to use JDBC when already on Ignite node?

xml config can not be used in jdbs and user code simultaneously
Hi all, when user uses the same xml config for jdbc driver and for his own ignite instance there can be : java.sql.SQLException: Failed to start Ignite node. Caused by: class org.apache.ignite.IgniteCheckedException: Ignite instance with this name has already been started: CustomeIgniteName because JDBC creates separate ignite instance, while user already has one with the same name. Of course that can be easily workarounded, user can support two configs or create jdbc connect first and then use Ignition.getOrStart(). However it's inconvenient for user and should be treated as usability issue. I see 2 solutions: 1) jdbc driver should use Ignition.getOrStart() 2) jdbc driver should connection string as ignite name. Thoughts? -- Thanks, Mikhail.
