JDBC stale connections and app hanging

Hello,
After a while idle my app stop working(it actually hangs) and after waiting all I get is the following exception message:
Caused by: java.sql.SQLException: Invalid or Stale Connection found in the Connection Cache
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)

at oracle.jdbc.pool.OracleDataSource.getConnection(OracleDataSource.java:165)
at org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider.getConnection(LocalDataSourceConnectionProvider.java:82)
My datasource is using following OracleDataSource config values:
connectionCachingEnabled: true
connectionCacheProperties: InitialLimit=50, MinLimit=50 , MaxLimit=200, PropertyCheckInterval=300, ConnectionWaitTimeout=60, ValidateConnection=true
Please, give me some help to figure out what is going on...
Thanks,

Hi,
The class OracleConnectionCacheManager provides a set of administrative APIs applications can use to manage the connection cache. Using these APIs, applications can refresh stale connections.
refreshCache API:
void refreshCache(String cacheName, int mode)
This refreshes the cache specified by cacheName. There are two modes supported, REFRESH_INVALID_CONNECTIONS and REFRESH_ALL_CONNECTIONS. When invoked with REFRESH_INVALID_CONNECTIONS, each Connection in the cache is checked for validity. If an invalid Connection is found, that connection's resources are removed and replaced with a new Connection. When invoked with REFRESH_ALL_CONNECTIONS, all available connections in the cache are closed and replaced with new valid physical connections.

How to improve jdbc 4 connection and Transact-SQL

I am using a jdbc 4 connection to connect to Database.
With code
Class.forName("org.postgresql.Driver");
String url = "jdbc:msql://athens.imaginary.com:4333/db_web";
username = �mycon�;
password = �mycon�;
Connection conn = DriverManager.getConnection(url, username, password);And quering and updating with database with TSQL
Sample code
Statement select = con.createStatement();
ResultSet result = select.executeQuery("SELECT key, val FROM t_test"); I am able to get the result
But i want to improve it.
Whether i should use any other api or any other configrational changes I need to imporove the rilibility and increase the speed.
Any suggestions?

Please don't cross-post. You have a thread for this in the JDBC forum (which is where it belongs, if anywhere), so keep the discussion there, please.

Unreliable connection and constant hangs

Hello.
Since a week ago, I've been having these troubles with lates version of Firefox hanging ALL THE TIME. I tried almost everything, nothing seemed to work. Today I tried reseting Firefox. And guess what? I can't make sure if it worked because now I have this problem with GOOGLE saying that it is an unrelieable connection. Specifics below:
www.google.com usa un certificado de seguridad no válido.
El certificado no es confiable porque ninguna cadena emisor fue proporcionada.
(Código de error: sec_error_unknown_issuer)
I'm sorry, my Firefox is in Spanish, but I guess the important part is the Error Code. Please help.

You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
*Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
*Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
You can see more Details like intermediate certificates that are used in the Details pane.
If <b>"I Understand the Risks"</b> is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
*Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
*Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.

Hey guys out there i have a problem with "App Store" not verifying connection, and app flickering!!

Post subject: NSURLErrorDomain error -1100 in OS X 10.8
If you check for software updates using the App Store in OS X 10.8 and get "NSURLErrorDomain error -1100" the problem may be with your Software Update preferences. This is particularly likely if you were using a custom Apple Software Update server. To solve the problem, quit the App Store, move the following two files (if present) to the trash, restart, and only then rerun App Store updates:
/Library/Preferences/com.apple.SoftwareUpdate.plist
/Library/Preferences/com.apple.SoftwareUpdate.plist.lockfile

I was recently trying to upgrade to mountain lion through the app store. I have unreliable Internet from a cable company whom I will not name, but we all know who they are. My Internet dropped while downloading the upgrade. Once I went through the notorious unplug the modem/router and plugged it back in to gain Internet connectivity again, I could not resume. No matter what I did, the app store kept displaying "an error occurred." I am hoping that those with the same issue read this first to save them hours of skimming through the Internet to find a solution. Here are the steps to take:
1. Make sure you have reestablished Internet connection
2. Chances are you got frustrated when you tried to resume/unpause the download and clicked the "X" to the left. If so, select the "Store" drop-down menu from the App Store and select "View My Account." There should be an option to unhide your purchase. You know what to do.
3. There is also an option to reset all warnings for buying and downloading under "View My Account." Do this, click "Done," sign out of the App Store and quit the App Store.
4. Open the Preferences in safari and select Privacy. Select "Remove All Website Data." Just do it.
5. Launch the app store and sign in.
6. Now, if you "Check for Unfinished Downloads" everything works peachy.
I hope this helps. Not much I can do for your Internet connection though.

JDBC Driver.connect seems to hang.

I've been using DriverManager.getConnection to get a connection to MySQL. This has been working fine until I tried to use it from a Threaded part of my application.
It seems to hang when it gets to the DriverManager.getConnection line and never return.
I googled about for hours and came up with that there may be a bug in DriverManager.getConnection which causes a deadlock. So I tried using the connect method directly on the driver but got the exact same problem of it hanging on that line.
I tried running my application (in Netbeans) with the 'Debug File' mode rather than just 'Run File' and everything works perfectly! No problems, which just seemed strange.
If anyone could point me in the right direction I'd be very grateful. I can supply more details if need be :)
Cheers,
stu.

It seems to hang when it gets to the
DriverManager.getConnection line and never return.Have you actually verifed this, for example by putting System.out.println statements before and after the getConnection() call? "Seems to..." implies that you're making an assumption which may not be true.
I tried running my application (in Netbeans) with the
'Debug File' mode rather than just 'Run File' and
everything works perfectly! No problems, which just
seemed strange. Doesn't seem too strange actually. That's what "race conditions" and deadlock conditions are about -- different timing in the app will cause different results.

MBP Beach Ball and Apps Hanging

Hi,
Increasingly this week I am finding that my MBP is getting the beach ball when opening something and any apps that I try to open just bounce in the dock and a long period of time.
If I leave the laptop to do what ever its doing and come back to it its sometimes back to normal.
I have run Onyx and ensured that the daily, weekly and monthly maintenance tasks have been run.
Any ideas would be appreciated.
Thanks
Gavin

HI Gavin,
Mac Maintenance Quick Assist
Run Disk Utility and Repair Disk Permissions;
Follow these instructions to verify the hard disk for errors:
Open Disk Utility, in the Utilities folder in the Applications folder.
Select your disk, and click First Aid.
Click Verify Disk.
If the disk needs repairs, do one of the following:
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the menu bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click Repair Disk. When Disk Utility is finished, from the Menu Bar select Utilities/Startup Disk. Select MacintoshHD 10.5 in the window and click: Restart
If you don’t have a Mac OS X Install disc, restart your computer while holding down the Shift key. As your computer starts up, it performs a disk check similar to the one Disk Utility performs.

How to configure to identify to reconnect on a stale connection?

Hi,
I am using oracle App Server 10.1.3.1.0 and oracle BPEL. BPEL uses TOPLINK over all of its Database Adapters. I am also using Oracle Server's connection factory and Data source in order to acquire a connection.
While execution due to some reason, connection pool loses connection with Database. Toplink is not able to resolve the stale connection and tries to connect which is leading to an errenous situation. Exception as:
[r]
Caused by Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061004)): oracle.toplink.exceptions.DatabaseExceptionInternal Exception: java.sql.SQLException: Listener refused the connection with the following error:ORA-12519, TNS:no appropriate service handler foundThe Connection descriptor used by the client was:mrtudev12:1521:xeError Code: 0. at oracle.tip.adapter.db.exceptions.DBResourceException.createEISException(DBResourceException.java:362) at oracle.tip.adapter.db.exceptions.DBResourceException.outboundWriteException(DBResourceException.java:410) at oracle.tip.adapter.db.DBInteraction.executeOutboundWrite(DBInteraction.java:933) at oracle.tip.adapter.db.DBInteraction.execute(DBInteraction.java:211) at oracle.tip.adapter.fw.wsif.jca.WSIFOperation_JCA.executeRequestResponseOperation(WSIFOperation_JCA.java:480) at oracle.tip.adapter.fw.wsif.jca.WSIFOperation_JCA.executeInputOnlyOperation(WSIFOperation_JCA.java:726) at com.collaxa.cube.ws.WSIFInvocationHandler.invoke(WSIFInvocationHandler.java:425) at com.collaxa.cube.ws.WSInvocationManager.invoke2(WSInvocationManager.java:416) at com.collaxa.cube.ws.WSInvocationManager.invoke(WSInvocationManager.java:222) at com.collaxa.cube.engine.ext.wmp.BPELInvokeWMP.__invoke(BPELInvokeWMP.java:736) at com.collaxa.cube.engine.ext.wmp.BPELInvokeWMP.__executeStatements(BPELInvokeWMP.java:371) at com.collaxa.cube.engine.ext.wmp.BPELActivityWMP.perform(BPELActivityWMP.java:195)

Please suggest that is there is a way that i can configure toplink to acquire a valid managed connection from Pool? or can identify between a stale and live connection?
Thanks

You need to define an ExceptionHandler and handle the code of reconnecting to the db in the ExceptionHandler. The following link should be of some use.

sadly you can. But because you shouldn't we're not going to tell you how.
Excel is no database, don't abuse it like it is.

JDBC - How can I detect a Stale Connection?

Hi There,
So here is my problem. My software is using a simple implementation of a connection pool to create/store/provide connections.
Every weekend the database is being shut down and restarted by my DBA. On Monday morning the application can no longer access the DB and I get errors like this:
java.sql.SQLException: No more data to read from socket
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:112)

at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1124)
at oracle.jdbc.driver.OracleStatement.executeQuery(OracleStatement.java:1264)
The connection pool is checking the connections to see if they are closed before giving them out but the check must be indicating that the connections are not closed.
What should I be checking to ensure that only live connections are passed to my application? Or do I need to change my approach to solve this problem.
Any info is greatly appreciated. Thanks.

Would executing a simple statement every time the
something requests
a connection take up a significant amount of time?
The general problem is that the client machine doesn't get notified that the connection is dead until it actually tries to use it.
Executing a simple query may or may not add a significant overhead to the application. It really depends on how much your application does between opening and closing a connection. The more processing it is doing, the less the overhead of a trivial statement.
Or your connection pool could automaticallyconsider
a connection stale if it has been open more than a
few hours and automatically close it and open anew
one.
But this wouldn't prevent that exception from
occurring
when the DB is restarted.I'm not sure I understand the concern here. If you say that a connection is stale after 4 hours or after getting used N times, you would provide some insulation to connections that had been idle in the pool for days at a time, which tends to increase the probability that something had caused the connection to fail.
In your case, I'm assuming that you have a pool of connections that are opened on Friday, become invalid some time over the weekend, and then are used on Monday. These connections would be "too old" for the connection pool to hand out on Monday morning, so the pool would presumably open new connections on Monday and close the old ones.
Your application could also be modified to catchthis
sort of exception and to retry a number of times
before reporting the failure.
When the DB is restarted the exception is reported
for all connections and
the app needs to be restarted to create new
connections.If the number of retries is sufficient, it should cycle through all the connections in the pool, which should force the pool to open all new physical connections. Of course, you might also add a method to your connection pool that forces it to return a new physical connection that gets called after N failures from your app.

App hangs on tab click if connection in use

If tab one is using connection1 and running a script and i click on tab2 which is also connected using connection1, the app hangs until tab1 finishes the script it was running and connection1 is again free.
Shouldnt each tab really open a new connection with the same parameters as the connection from the connections list? If not then it should at least not let you select any tabs using connection1 while connection1 is busy so that you can continue working on tabs with other connections.
I am using 1.5.0.53 on windowsxp.
Thanks

By default, all worksheets use the same single threaded connection. To get a worksheet with an unshared connection, use ctrl-shift-N

Mail app hangs on ios5 and gmail account

The Mail app hangs several times per day. I have one gmail account. The diag. files says something like "com.apple.mobilemail failed to resume in time" or "Power assertion timeout for MailPendingChanges"

This connectivity issue between my Apple Mail through CLEAR as ISP to Godaddy's pop.secureserver.net is just getting weirder. Now my 9 boxes spin out (when upload is testing at .07 mbps and also at .54 mbps) but partner's 4 emails on iMac using same settings through same network is fine...was glitched a while ago too though. Then partner's emails all do same thing, and hers and my Gmail accounts check fine. SO, Helllloooo Godaddy, if Gmail checks fine but your pop.secureserver.net does not, maybe it IS a problem on your end? Of course, getting Godaddy to ADMIT THEY HAVE A PROBLEM would be a miracle.
Still zero reply or help from either Godaddy or Clear, no resolution from either, still pitching blame at each other.

Using Remote app on iPhone 5 without a separate internet connection and wifi router.

Hi,
I need to be able to control iTunes within my MacBook Pro remotely. Using my mobile broadband service and wireless router I've been able to get the Remote app to allow my iPhone 5 to do the job nicely through Home Share. So I went and bought a separate WiFi router and tried to do the same thing. Of course when it didn't work, I discovered that I need an internet connection and WiFi network to make the Home Sharing work.
So I got to thinking, can I create a WiFi hotspot using the Personal HotSpot functionality of my iPhone, set up Home Sharing on phone and MacBookPro and then use the Remote app. Ideally this would work as it seems all the key components are in place.
The MacBook Pro accepts the iPhone hotspot as a means of Home Sharing, however the iPhone won't use the personal hotspot to Home Share and I can't connect to the iPhone personal hotspot on the iPhone itself.
Does anyone know how to make this work for me? It would be such as neat solution if I can get it to work - not to mention the potential to save me about $200 (I need to set this model up for two people).
Cheers
Kathy
