We are also getting an INFO Message: "INFO: No connection to system BWSAP available"
What makes it very strange is that this error only happens when executing this specific report, with other reports we do not get any errors, although on a couple of reports we get the INFO Message, but no error, the report is executed correctly. We are using EP 7.0 and BI 7 SP 13. BWSAP is the system alias for our connection with BW.
Any suggestions?

The problem it seems was caused by a conflict between a couple of system connectors. They both had the same configuration, the only difference was their alias. One of them was the "master system" and the other was not, but because of the configuration, it was causing conflicts with the other one. By deleting this extra connector, things went back to normal.

No LDAP connection available

Hi,
We are developing a Webcenter portal application using Webcenter 11g along with UCM 11g.
We have integrated the Weblogic with external LDAP(i.e) we r not using the default LDAP comes with Weblogic
We have also integrated the whole set up with OAM. We are using RIDC APi to check-in/update/fetch the content from UCM. We are facing following issue,
1. We are able to login to UCM Admin console and check-in the content. But we are unable search and check-out the content via UCM Admin cosole . We are getting the below exception,
Caused by: oracle.stellent.ridc.protocol.ServiceException: Unable to retrieve search results. Unable to execute service method 'getPreferredLanguage'. oracle.security.idm.IMException: oracle.ods.virtualization.service.VirtualizationException: oracle.ods.virtualization.engine.util.DirectoryException: LDAP Error 1 : No LDAP connection available to process request for DN: cn=orcladmin.. oracle.ods.virtualization.service.VirtualizationException: oracle.ods.virtualization.engine.util.DirectoryException: LDAP Error 1 : No LDAP connection available to process request for DN: cn=orcladmin.. oracle.ods.virtualization.engine.util.DirectoryException: LDAP Error 1 : No LDAP connection available to process request for DN: cn=orcladmin.. javax.naming.NamingException: No LDAP connection available to process request for DN: cn=orcladmin..
2. Also we are getting the same exception when we try to check-in/update/fetch the content from the portal application via RIDC.
Is there any config is missing or else as external LDAP is configured is there any configuration required at UCM end as well as in RIDC end
Thanks in advance

Hi ,
I am getting the same exception.Have you got the solution for this.

Comcast just replaced my cable modem/wireless router. All devices connect properly except my iPhone 4. It shows itself to be connected to the network, but it does not load any web page. Resetting the iPhone does not solve the problem. Any suggestions?

Thank you for your response.
I had rebooted the router (several times, actually), to no avail.
I do not know the answer to whether MAC filtering is enabled on the router. Have tried to find info about that, but unsuccessfully. Router is an Arris TG852G, supplied by Comcast. I would be surprised if MAC filtering were the issue, since in addition to the computer, we have successfully connected several other devices to the wifi, namely an iPad, a Android phone and a Kindle Fire - all able to access internet pages through the wifi, and all without a need to add the device to a MAC address whitelist. To add to the mystery, the Comcast tech was able to connect his iPhone 4 to my network and access web pages. He was unable to connect my iPhone, however, after trying for some time.
I seem to recall reading somewhere that an iPhone cannot connect to a wireless "n" router, only "b" or "g". The Arris router is described as a n/g/b compliant router, and as noted the Comcast tech was able to connect his iPhone, so don't know why that would be the issue here.
By the way, my iPhone does connect wirelessly to my network at home. This difficulty is at a second home.
Any other thoughts would be appreciated.

IFS-10620: Unable to construct connection pool exception

I am getting the "IFS-10620: Unable to construct connection pool" exception on the browser
when I try to run the Airport example from the "Writing an iFS Custom Renderer" http://technet.oracle.com/products/ifs/htdocs/xsl/index.htm
technical brief.
Technet tells me that in this case I should (a) run it under jdk 1.1.8, and
(b) have classes111.zip from the jdbc directory included in the classpath.
(c) DatabaseUrl field in IfsDefault.properties is defined properly.
I have modified one of the classes to output the relevant system parameters when
initialised, and I get the enclosed output in (a) on loading the servlet.
Together with paths (b) and classpath(c) settings,it seems that the requirements
are met but it still gives the error. Any suggestions of where we go wrong?
Oracle, IFS and JWS are installed on the same NT machine, and the iFS GUI works.
The value of the DatabaseUrl field was empty (juts "@", I then changed it to
"@machinename" but to no avail).
Thanks

iFS API is working only with jdk1.1.8 ?
I'm just using your API and I can assure you that IfsDefault.properties is as you advice and inluded in classpath.
Please reply if you have any solution to this
Thank you verry much

I want to connect my Mac Book Pro to the internet in France without any wifi connection available? Mi Fi? Sim card?

I want to connect my Mac Book Pro to the internet in France without any wifi connection available? Mi Fi? Sim card? All we have is a phone signal in this rural French location. I want to be able to Skype to states from there. We have a friend with a 3G ipad who uses an Orange sim card to do it. I would rather not have to buy an Ipad.
thanks

I found out that the data package for one month useage with MiFi is 1G. How many minutes of online time does that correspond to?

Pc suite "no connections available"

Hello
I need your help about Nokia PC Suite and Nokia Ovi Suite.
I use Nokia PC Suite many years without any problem until last week.
After I formatted my pc I reinstalled the latest version of Nokia PC Suite but when I try to connect my Nokia E71 I receive the message “no connection available”.
Indeed under the “manage connections” tab there is not any connection
(USB cable, infrared (IrDA), or Bluetooth).
I uninstalled Nokia PC Suite and I installed the Nokia Ovi Suite but my E71 “cannot be found”. I tried many different procedures the last three days but…nothing.
All the rest of the programs I reinstalled after formatted my pc work perfect.
My system’s details:
Windows XP Professional 32-bit (for first time I updated to Service Pack 3).
Intel Pentium 4 CPU 3.20GHz
RAM: 512
About the Bluetooth version here is what I read in Control Panel / Bluetooth Devices / Hardware:
BCM2035 Bluetooth 2.4 GHz Single Chip Transceiver.
Microsoft Bluetooth Enumerator.
Please could anyone you tell me what mistake I make?
Thank you.

512 MB RAM? You need more than that, my friend.

Connection Reset exception received in Windows only

Hi,
I have two instances of my java app, one on Windows, one on Linux, both connected to the same cpp app running on Linux, and the machine running the cpp app is very heavily loaded. After some time, only the windows java app gets a Socket Exception (Connection Reset), not the linux.
In fact, after connecting to the cpp app, the java app starts a number of transactions with the cpp app, requesting data from the cpp app. The trasanctions are timing out on Windows, but not on Linux.
Does anyone have any idea why this might be happening?
Thanks for any help,
Regards,
Shefali

Hello,
I have the same problem. My java TCP client detect disconnection (Connection Reset exception is generated) after about 60 seconds. With Suse 10 it make more then 15 minutes!!!!
This is not normal of an application that it takes that long to detect a disconnection! Is there a way of changing/configuring the timeout of the TCP/IP layer of the OS?
Thanks in advance for your help.

Rmi client throws Connection Refused exception

My Rmi client throws a Connection Refused exception when i try to run it on remote machine (in this case i run it on my virtualbox macine).
The virtualbox machine network is in NAT mode (host machine ip should be 10.0.2.2).
When rmi client starts get registry instance and print in standar output:

I'm solved my problem.
I just need run my server with -Djava.rmi.serverhost=10.0.2.2 and my client running on my virtualbox machine works!

Failed to get connection-; Root exception is: java.lang.NullPointerExceptio

Hi:
When I login Applications, click on any OAM got the following errors. All the forms are good.
An error has occurred!
Failed to get connection-; Root exception is: java.lang.NullPointerException
I don't know when started to be like that but I applied some patches yesterday. Thank you for your help in advance.

Hi;
You dont need to check log file. Please check apache log file for error details.
By the way did you try to
1. close apps services
2. run autoconfig on dbtier than
3. run autoconfig on appstier and be sure you dont have any error message,than recheck issue

Connection Refused Exception.

Hi! I have made a java server as an NT Service. This server and my client works fine when I run them from command prompt. But when I make the server as an NT service and then try to connect to it using this client, I get an exception saying connection refused. Can anyone help me with this, its urgent.
thanks
rahul

This is the client program
import java.net.*;
public class Client {
public static void main(String[] args)
try
Socket mySocket = new Socket("localhost", 4000);
System.out.println("Connected");
catch (Exception e)
System.err.println("Exception: " + e);
This is the Server Program
import java.io.*;
import java.util.Date;
class MyServer {
int m_port;
ServerSocket m_serverSocket;
public static void main(String[] args)
new MyServer(4000);
public MyServer(int port)
m_port=port;
try {
init();
catch (Exception e)
System.out.println("Caught : "+e);
public void init() throws Exception
m_serverSocket = new ServerSocket(m_port);
while(true)
Socket client = m_serverSocket.accept();
Thread clientThread = new Thread(new ClientHandler(client));
clientThread.start();
public void close() throws Exception { m_serverSocket.close(); } }
and this is the ClientHandler PRogram.
import java.io.*;
import java.net.*;
import java.util.Date;
class ClientHandler implements Runnable {
Socket m_socket;
public ClientHandler(Socket clientSocket) {
m_socket=clientSocket; }
public void run() {
try {
processRequests();
m_socket.close();
catch (Exception e) { System.out.println("Caught "+e); }
public void processRequests() throws IOException {
DataOutputStream dout= new DataOutputStream(m_socket.getOutputStream());
dout.writeChars((new Date()).toString()+"\n"); } }
...The point is that they run perfectly on command prompt but not when i make this server as nt service.
What could go Wrong ??
thanks

Connection Leak Exception in farm runs

Hi
I am trying to use the ADFBC to get a list of values for my backend data which will be displayed in the UI later. In the view, it works fine. There have been no errors. But during the farm runs there is an intermittent issue of the Connection Leak Exception.

The scenario is that I launch a page which has a region. This region needs to get a list of values from the backend. These values are coming from a VO.
This issue happens only in the farms and I guess at times from the view, but doing a bounce of the server resolves the issue.
Is there any setting that needs to be done ?
Thanks

Jdev. Db connection - Io exception: The Network Adapter could not establish

Hi,
I installed Oracle 9i and forms 9i in my PC. Both are working fine including SQL.
Now i would like to use Jdeveloper. When i try to create a database connection "Io exception: The Network Adapter could not establish the connection" error returned.
My Db connection details are
Driver thin
host name harry
jdbc port 1521
sid oradb
where oradb is database name and harry is host name.
also i try to give the following details in Enter Custom JDBC Url option
jdbc:oracle:thin:@harryt:1521:oradb
But, i get the same error. So, can you pl. help me to fix this problem.
- Murali

The Network Adapter exception is caused because:
1. The database host name, port number, or database instance name is wrong.
2. The database TNSListener has not been started. The TNSListener may be started with the lsnrctl utility.
C:\>lsnrctl start

Iphone 5. cannot get mail. no internet connection available.

I have the iphone 5. My carrier is Sprint. I can get email only when connected to wi-fi. When no wi-fi is available I get a pop up message that says: cannot get mail. no internet connection available.
I am sure I am just missing a setting or something to correct this. Any ideas?
Thank you!

I experienced this problem firsthand with a Sprint iPhone 5 about a month ago, telling me it had no internet connection and could not check my email (which was Gmail, set up through the native Mail app, using default settings). I can confirm that restarting the phone (holding home + power buttons until restart) temporarily fixed the problem but it quickly returned. Toggling Airplane mode did nothing. The problem did return within the same day after a period of time. I have since switched back to AT&T.
Interstingly, my sister had the same issue with her brand new Sprint iPhone 5 this week. She called Sprint and the customer service representative confirmed that this is a problem that only affects Sprint iPhone 5 users who use Gmail. The rep told her that it affects Gmail both in the native Mail app and also in the Gmail app, but web use still works (I haven't confirmed this). The rep also said that Sprint is aware of the problem and working on a fix that would be delivered in the form of a "software update" but there was no clarification if that was an iOS update or a Sprint carrier update.
That's all the info I have now, but if you're a Sprint iPhone user and experiencing this problem, please do call Sprint and let us know what you find out.
