Query based on ODS showing connection time out

Hi,
I have a query based on an ODS. The selection criteria for the query is Country which is a navigational attribute of the ODS. When i exceute the query using a country with lesser volume of data the query runs fine. But when i choose a country that has more number of records the query shows 500 connection timeout error sometimes and sometimes it runs fine for the same country.
I tried to execute the report using country as input variable - First i executed the report using a country with lesser volume of data it worked fine as usual and then i added another country with larger volume of data in the filter criteria and the old problem cropped up.
Could you please suggest a solution?
Appreciate your response.
Thanks
Ashok

Hi,
Its not recommneded to have a query on DSO which gives huge amount of data as output.
For small amount it should not be a problem.
Shift your queries to a multicube as recommended by SAP and build the multicube over the cube which loads from the DSO.
SAP recommends to create queries only on multiproviders.
If not possible then you can try to create indexes on DSO on the characteristics field which are used in filter and global selections in the query.This can improve the query performace.
But this will create performance issue while loading data to the DSO.
So you need to do a trade off.
Thanks

HT4628 my powerbook g4 os x 10.5.8 leopard is showing-Connection time out while connecting to the wifi.however it showing all available wifi connections around but not connecting it..however ethernet is working

Problem while connecting with Wi-Fi,
When i am connecting my powerbook g4 leopard to any Wi-fi connection it showing -Connection time out, however Ethernet is working .I have updated all softwares but still same problem.

It's possible that either the internal AirPort Extreme card or the antenna is faulty or has failed.
One last thing to try before going with another Wi-Fi solutions is to the following:
Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)
3. Run the Disk Utility to repair Disk Permissions.
Restart or log out then back in.
4. Turn off the Mac OS X Firewall
System Preferences > Sharing > Firewall
Click the "Stop" button.
5. Create a New User Account
System Preferences > Accounts
Click "+" to add a new account
Log off, then log back on with the new user account.
Try connecting with the AirPort.
If none of these help resolve the issue, you may want to consider getting a USB wireless adapter to replace both the internal card and antenna. One such vendor of these adapters is Other World Computing (OWC).

SOAP Adapter: Connection time out error

Hi Guys,
I do it one scenario for Proxy to webservice Asynchronous . I have send the input details through Proxy. In Sxmb_Moni shows success message. But Receiver side doesn't reach the payload. Because receiver side (Soap Adapter) shows connection time out error. But i have given correct URL and SOAP Action in receiver communication channel. Please give some suggestions to solve that issues. Please don't refer links.
Thanks & Regards
Vijay

hi
this is a time out error
increase the timeout value by specifying the parameter
XI.Timeout in the module parameter of soap Adapter
OR
1. This is because of TimeOut. The default timeout value for synchronous calls is 5
minutes. You can increase this value by setting parameter XI.Timeout in the module parameter table of
the SOAP adapter. The value must be given in milliseconds. For example, value 600000
represents the timeout value of 10 minutes. This parameter is not recognized in systems prior to SP13.
2.The Other Options is send the queue id with your request message.
http://host:port/XISOAPAdapter/MessageServlet?channel=p:s:c
&version=3.0&...&QueueId=xxxxxxxxxxxxxxxx
where xxxxxxxxxxxxxxxx is an ABAP queue ID.
3.Check your RWB message monitoring.
Is there any system failure message and holding message be there.
If then clear the messages.
4. Increase the time out parameter for HTTP in your altova xml spy.Defaultly it will be very low.

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!
Horus

All 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.

Could you guys please help me out here?

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
... ok? ...

Java Socket Connection Time out

Goal*
I want to check host/port availability of computers in our network (~100 computers) .. Just check if host is alive and if it has port 445 opened. I want to do this somehow in parallel, so the code execution is as quick as possible.
My implementation*
I do this by creating socket connection to the host. Something like this:
        Socket s = null;
        try {
            s = new Socket();
            InetSocketAddress socketAddress = new InetSocketAddress(ipAddress, 445);
            s.connect(socketAddress, 3000);
            if (s.isConnected()) {
                // do something
        } catch (ConnectException ex) {
            //exception thrown
        } catch (IOException ex1) {
            //exception thrown
        } finally {
            try {
                // close socket
                s.close();
            } catch (IOException ex) {
                Logger.getLogger(ComputerModel.class.getName()).log(Level.SEVERE, null, ex);
        }This code is executed in a loop, where a separate thread is created for every iteration = ~100 separate threads.
Problem:*
1.
It seems to me, that first ~10-15 connections are created ok, but then my code reaches 'IOException' catch block for every subsequent itteration and ex.getMessage() returns "connection time out" (I try to use different timeout values in the 2nd parameter. Values from 3000 up to 20000).
Is it valid to create 100 separate threads in a loop? Can't I make my NIC to bussy with this ??? What is the maximum ammount of threads, I can create? I did not use threads before, so I have no idea, if max values are near to 10, 100, 1000, or 10000 ..
2.
After my code is executed, I enter 'netstat -an' command in my command line and I get bunch of connections, which report status of SYN_SENT for several connections.
TCP 10.20.11.140:4557 10.30.11.119:445 SYN_SENT

TCP 10.20.11.140:4565 10.30.12.21:445 SYN_SENT
TCP 10.20.11.140:4566 10.30.11.150:445 SYN_SENT
I also feel, that my computer network response (e.g. firefox browsing) is a bit slower ..
How shall I handle this problem properly?
Thx in advance,
Juraj

The documentation for netstat explains what SYN_SENT is, but
I don't know why you have them.The app has asked the TCP stack to transmit SYN
the TCP stack is now waiting for SYN-ACK.
If there is no host at that IP address or a host that drops connections (SYN packets) for TCP port 445
there will never be a SYN-ACK.
After a few minutes the TCP stack will time out the connection attempt.Yes, I was rather commenting on why his hosts aren't answering. I thought that his case was that all of them should answer :)Akkurat. I was answering more for clarification.
Someone who does not know your posting history could easily assume you meant
it was a mystery why netstat was showing SYN_SENT.
And I figured it would not harm to hint that one possible reason would be that those machines are powered off (no host).

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

Also, there may be other factors to consider depending on your scenario. If you don't have it already, look at the latest <a href="http://service.sap.com/~sapidb/011000358700005909032005E/XI30XI70_TroubleGuide.pdf">XI Troubleshooting Guide</a> - Section 9.2 on "Timeouts in XI".

Connection time out

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 :

Connection time out error

Hello sir,
Whenever i install addon on SAP B1 i get connection time out error can anyone help me

Manish,
it depends on how you set your connection. it must be through command line argument. if you have set your connection string as
sConnectionString = "0030002C0030002C00530041005000420044005F00440061007400650076002C0050004C006F006D0056004900490056"
then change it to
sConnectionString = Environment.GetCommandLineArgs.GetValue(1)
and give the connection string 0030002C0030002C00530041005000420044005F00440061007400650076002C0050004C006F006D0056004900490056 as your command line argument in project properties -- Debug tab. prepare the addon ard and try installing it.

Connection time-out issues each first try of pacman

Hi,
I am new to arch. I keep getting a connection time-out each time I use pacman for the first time. I have to do a ctrl+z to stop the command and then delete the db.lck file and then when I run pacman again, any operation on pacman that I had tried works flawlessly.
Do I need to do something to fix this? I check there was a similar thread in 2012, but it ended without any results.
Cheers,

I'm pretty sure you can disable all the mirrors you don't want to use, try lowering the list to only those in Asia to minize your waiting time atleast. I get a time-out occasionally on the first run, but running anything inside China's GFW is a roll of the dice.
