Oracle Sql Developer Connection Is Currently Busy
it only takes a minute: Sign up How can I keep Oracle SQL Developer from closing the DB connection? up vote 28 down vote favorite 5 Is there any way to keep Oracle SQL Developer from closing my DB connections, or to increase the timeout? Sometimes during a long-running query SQL Dev will just close the connection, leaving my query oracle sql developer connection to oracle database running on the server but me with no results. If I RDP into the server and run SQL Dev locally it never seems to have this problem. oracle oracle10g oracle-sqldeveloper share|improve this question asked Aug 20 '09 at 22:48 Kevin Babcock 5,775145076 Related question with solution for SQL Developer 4: stackoverflow.com/questions/12999811/… –Vadzim Feb 23 '15 at 10:41 add a comment| 6 Answers 6 active oldest votes up vote 7 down vote accepted This doesn't sound like an issue with SQL developer, cetainly I've never come across it. Are you sure it's not something else, like your network?

This problem only appeared after I upgraded from 4.0.3 to 4.1.3. I frequently work at a location where the network connection is flaky and gets reset every now and then. Previously, I could just disconnect and reconnect, but this bug now requires me to close SQL Developer down completely in order to reconnect.1. Open SQL Developer, connect to a session, do some work.2. Interrupt the connection (e.g. pull network https://community.oracle.com/thread/3881596 cable, then plug in again).3. Disconnect SQL session.4. Open a SQL Worksheet with a SQL query.5. Click Run Statement (F5). "Select Connection" pops up.6. Choose a connection using SSH tunnel.Error encountered "IO Error: The Network Adapter could not establish the connection; Vendor code 17002"7.

minding your own business, doing your work, and you click in your favorite Oracle Database IDE. Do you get what you asked for? No! Instead, you are rewarded for your troubles with this puzzling and frustrating message. What the heck?!? Abort? Try again? Busy? http://www.thatjeffsmith.com/archive/2013/09/oracle-sql-developer-and-the-dreaded-connection-busy-message/ The Long Answer When you connect to a database in SQL Developer you are actually http://www.dba-village.com/village/dvp_forum.OpenThread?ThreadIdA=31399 making two connections. We use one connection to run background queries in the the worksheet. This makes the code assist features work. The other connection is used to do EVERYTHING else. The only exception is when you open an UNSHARED worksheet. It's called ‘unshared' because we open another dedicated connection just for that worksheet. So, if you see this message in sql developer SQL Developer, it means your request has timed out while waiting for the main connection to become available. For example: when you ask to see a table's data in a table editor, we first ask to lock the JDBC connection so we can run our ‘SELECT * FROM…' query. If the JDBC comes back and says, sorry we're busy, we try again. We give up after a certain amount of time and give you the error message. oracle sql developer At that point you get to: Try again - ask for the lock to run the query again Abort - give up Now, I realize this explanation has only given you more questions to ask, so let's go through those now. But I'm not doing anything, how could the connection be busy What's probably happening is the columns page query is still technically executing when you go to click on the ‘Data' page in a view or table editor. Or, something you're doing somewhere else in the tool is still using the main connection. Still don't think you're doing anything? Do you have any reports (or Monitor Sessions) on auto-refresh? Or maybe you've gotten cute and installed/created a ‘keep alive' extension to thwart connection-idle disconnects? Oh yeah… In earlier versions of SQL Developer you might run into this error more frequently because of poor session management - that's on us. But in version 4, you should VERY rarely see this message. In fact I've been spending the entire morning trying to get this message to pop-up and I failed. Even if I click ‘Abort' the data comes back anyway?!? The dance of the ‘are you busy' and the ‘yes we are' is colliding with the timeout perfectly just so that the dialog is triggered as we're able to run the query for you. If you see this frequentl
