Transaction on Oracle 9i data source connection times out before JTA transaction
Hello,
I have a MDB with a long-running transaction (3600 second timeout).
In the MDB, I make a call to another EJB that has its transaction
attribute set to NotSupported (I do this because I need
non-transactional semantics in the called method).
If the EJB call take more than about a minute to complete, then I get a
datasource error when using the data source in the MDB after the return
(see error at bottom). However, if the call completes quickly, then I do
not get this error. It seems like the datasource connection somehow
times out, but I don't see where I can change this timeout.
pseudocode:
// timeout set to 3600 seconds
transactional MDB onMessage() {
// receive connection from Oracle BEA driver
// myEJB performLongOperation has transaction attribute
// set to NotSupported
String result = myEJB.performLongOperation();
// use connection from Oracle BEA driver
If the performLongOperation takes more than about a minute, then I get
the following error when using the connection after the operation:
Caused by: java.sql.SQLException: XA error: XAER_NOTA : The XID is not
valid start() failed on resource 'Oracle IDENT Connection Pool':
XAER_NOTA : The XID is not valid

Thanks for the reply.
I don't have contract customer support access with BEA, and thus I can't
download the patch. Is there any other workaround for this?
Thanks

Change all reports data source connection
I have numerous SQL reports that require their data source connection changed. Does anyone have code to change all reports that use a data source name of 'Data_Warehouse_Main' to a different shared connection.
ThanksHi BiscuitB,
According to your description, there are numerous SQL reports and their data source need to be changed. You used RSScripter but it does not work.
In Reporting Services, if we want to change data sources of multiple SSRS Report, we can use Powershell to set the data sources for an item in a report server database or SharePoint library. To achieve your goal, we need to use both the Reporting Service
GetItemDataSources Method and the SetItemDataSources Method. You can refer to the thread provided by PrajapatiNeha, and the PowerShell script sample will be helpful for you.
Reference:
GetItemDataSources Method
SetItemDataSources Method
If you have any more questions, please feel free to ask.
Thanks,

Oracle Explorer connections times out -- cannot reconnect
Hello
How do I reconnect to the database about the connection times out?
Sometime I go to the Oracle Explorer to check some things out in the database, then switch to coding for a while -- maybe 30 minutes or so.
When I go back to the tree to check something, it says basically "not connected". I'm assuming it has timed out. However there doesn't seem to be an option to reconnect without closing Visual Studio and reopening it.
Am I missing something?
Thanks!
HorusAll you need to do is close the connection and reopen it. you do this by right clicking on the connection node in oracle explorer, from the menu that shows up select Close connection. again right click on the connection node in oracle explorer, from the menu that shows up select Open.

Managing data source connections inside an Excel workbook for deployment reasons
Hi,
with a certain frequency, I use Excel to show SQL Server data, or SSAS data, etc. in tables, pivot tables, ...
So, a single Excel workbook can contain more connections and ofter a same connection is used.
When an Excel is deployed to a prod environment from a test environment an issue it to update each data source connections by specifing the prod server and/or the prod instance. To avoid to accomplish the boring task to change each single connection,
is it possible to perform it in a more simple or automatic manner?
Any ideas, please?
ThanksHey pscorca,
When you deployed Excel files to a product environment, why did you need to change the data source? Did you move SQL server DB and SSAS DB to the product environment too?
And when you click Data->From SQL Server/From AS ,then Excel should create a Office data connection file which is usually saved in: C:\Users\Username\Documents\My Data Sources . If you have multiple Excel files need to use the same connection,
you can choose the Existing Connections, then select the odc file. If you want to change your connections, you just need to Edit the .odc file.

Internet connection times out when downloading update ios5. get to last 0.01 of data, says processing file and then says connection timed out. Is there a fix?
I am using itunes 10.5. Update didnt work on last software but restore did work. HelpAfter two days of attempts, Google & Apple searches, one Apple post stated to turn off all firewalls and virus software and keep trying since there were 6 gazillion people trying to update. I have Windows 7 & Kaspersky and had to diable every single safety feature in Kaspersky as well as Firewalls and it finally allowed the download and update attempt.
Glancing at the forum, there appears to be numerous other problems with missing pictures, text problems etc after the IOS5 download but fortuneately, everything seems ok so far. Good luck, it is frustrating! Hattie47 -
I am having Macbook Pro, I have recently tried updating my operating system to OS Yosemite, but after that its giving problem in connecting to Wifi. The error is "Connection Time out Occurred". Its getting connected by Ethernet cable.
Take each of the following steps that you haven't already tried, until the problem is resolved. Some of these steps are only possible if you have control over the wireless router.
Step 1
Turn Wi-Fi off and back on.
Step 2
Restart the router and the computer. Many problems are solved that way.
Step 3
Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
Step 4
Run the Network Diagnostics assistant.
Step 5
In OS X 10.8.4 or later, run Wireless Diagnostics and fix the issues listed in the Summary, if any.
Step 6
Back up all data before proceeding.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
Step 7
You may need to change other settings on the router. See the guidelines linked below:
Recommended settings for Wi-Fi routers and access points
Potential sources of interference
Step 8
Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
Step 9
Reset the System Management Controller (SMC). -

I am stuck and don't know where else to check.
Could you guys please help me out here?
Thanks.That tnsping error indicates several possible problems, most related to the setup for the client. Or network setup on the database server host.
Connecting to a database using sqlnet requires three things, the database host, the listener port, and the ORACLE_SID or instance SERVICE_NAME.
The tnsping utility is only concerned with the first two items, host and port. It will not perform an actual connection, and will not verify the tnsalias ORACLE_SID or SERVICE_NAME values.
An "OK" result from tnsping verifies that the specified host has a listener running at the specified port and it is servicing connections.
Since you're not getting an "OK" from tnsping, could be something is blocking the connection (i.e. firewall), the host= specification is not correct, or the port= spec is not correct. Note that host= must either be a valid and correct hostname, or a an IPv4 address. If IPv6 is in the mix, only the correct hostname will work. A hostname that resolves correctly.
Look at your network interface setup on the host, find its IP address, make sure the IP will `ping`, and try a new sqlnet.ora entry with the IPv4 address.
ifconfig -a
<interface>: flags=...
inet n.n.n.n
# in sqlnet.ora:
xe2 = ... host=n.n.n.n ...
tnsping xe2

Itunes update to firmware fails, because connection times out.
I have been unsuccessfully attempting to update my iphone 3gs and ipad to iOS 5 for over a month now. I have spent many, many hours on this, and many phone calls to apple support. I disable Norton 360, and windows firewall, and my firewall on my router. I've tried updating my router's firmware, which bricked the router--thanks apple for insisting this was the problem, and I have replaced the router, with a new one. Itunes diagnostics gives me the following information. I am using itunes as the administrator in Windows 7, 64 bit, although itunes doesn't recognize it, unless I reinstall it as the administrator, but then once I restart the computer, itunes no longer recognizes that I using Windows as an admin.
Also, the firmware cannot update, because the connection times out, despite all my firewalls, and antivirus being turned off.
I've tried downloading iOS 5 and then updating using restore, but that didn't work. I've poured through support forums, and error codes: I get 1611, etc. Cannot seem to resolve this.
Any ideas?

Message Mapping - connection time out
Hi ,
I hae just created a message mapping and when I click on Test tab and load a payload in source and try to test the mapping , it gives me connection time out error from java...
What could be wrong ? Mapping involves an XML to IDOC .
Cheers,Hello,
I think so (Experts, please correct me if I'm wrong). Before, we had a scenario in which the external definition was about 960kb. It really did post issues when testing in the message mapping itself. There are three options:
a.) Use less detail in your sample message mapping, in this way you can correct the error in the mapping itself.
or
b.) Test in operation mapping, and then do the correction in message mapping afterwards. If the testing is successful, make sure that you don't click the drop down icon. Instead, export the result as a zip file and then extract it. (if this hangs, go for c)
or
c.) Test at runtime
Hope this helps,
Mark

Hello everyone,
I'm using modem PK5000 from Century Link. My other two desktops are using Window and in the same room w my modem.
I got connection time out every time my computer started playing the screen saver.
All I have to do is restarting my modem but it's so unconvinience.
I called Century Link customer service and all they told me is changing the channel but it didn't solve the problem.
At school and other people's places, my wifi works just fine.
I used cleanmymac about a month ago and this problem started a week ago.
Can cleanmymac cause the problem? If so, how can I check and fix it?
I check the apple store to update my software but everything is up to date.
Can it be the firmware of my modem? My brother who uses the two desktops (and they connect to the modem with LAN cables) upgraded firmware last week and it seems like when the problem started.
And when my Mac loses the wifi signal, my printer still has the signal, but my desktop cannot log-in to page 192.168.0.1 which manages the modem and wifi even though the desktop connects w my modem by LAN cable and it still connects to the internet.
If you have any clue, please help!
Thank you so much!Thanks Todd, Wayne,
this network timeout sure seems to be the guilty one!
I've changed it, lets see if it's fixed but sure looks like it.
The thing is that I was looking for GWWS tuning here :
