OIM Null Connection Errors

We have OIM 9.1.0.2 configured in our environment. I am seeing a lot of GOT A NULL CONNECTION errors in the application logs. But when we contact the DBAs, they are not seeing any errors on the database side. I am seeing only from the application side. We are running on OAS 10.1.3.1
here is the error:

Error: Found Null Connection

Using JDeveloper, I set up a connection with success. However, running the program generates the following error:
java.sql.SQLException: found null connection context
The error persists even when I use [contextNameFromtheConnection] with #sql{...};
Fortunately, when I switched back to SQLJ code only, setting up the connection using Oracle.connect(...), it works in JDK 1.18, but not in 1.2.2. Furthermore, by doing so, I had to leave the JDeveloper Connection standing there useless. I even can not delete it from the upper-left Navigator pane!
I really appreciate your help. Have fun and sleepless night with ORACLE.
Thanks for your time.

ADF: Gracefully handling JDBC connection errors? Part II

Hi gang
I while back I posted a forum post to find a solution to "display a specific web page when the JDBC connection drops out on our ADF application, specifically the following error: oracle.jbo.DMLException: JBO-26061: Error while opening JDBC connection"
...you can see the original post here:
Re: ADF: Gracefully handling JDBC connection errors?
For the life of me I can't get this to work now. It appears I can't redirect to another page during the call to reportException. I've had a play with different methods of redirecting, as seen in the following code sample:
public class ErrorHandlerImpl extends DCErrorHandlerImpl {
public ErrorHandlerImpl() {
    super(true);
@Override
public void reportException(DCBindingContainer dCBindingContainer, Exception exception) {
//    try {
      String message = exception.getMessage();
      if (message.indexOf("JBO-26061") >= 0) {
        // Method 1
        FacesContext fc = FacesContext.getCurrentInstance();
        UIViewRoot viewRoot =
        fc.getApplication().getViewHandler().createView(fc, "faces/errorPage.jspx");
        fc.setViewRoot(viewRoot);
        fc.renderResponse();
        // Method 2
        // FacesContext fc = FacesContext.getCurrentInstance();
        // fc.getApplication().getNavigationHandler().handleNavigation(fc, null, "goError");
        // fc.responseComplete();
        // Method 3 - required IOExcepition handler
        // FacesContext.getCurrentInstance().getExternalContext().redirect("faces/errorPage.jspx");
      } else
          super.reportException(dCBindingContainer, exception);
//    } catch (IOException e) {
}... with no success.
Has anyobody any other solutions or advice on getting this to work?
Your help appreciated.
Thanks & regads,
CM.
PS. JDev 11gR1 ADF BC + ADF Faces RC

Hi Frank
Yep, I' tried redirect, that was method 3 (you can see all 3 methods I've attempted, last 2 are commented out).
With the declarative ADFc exception handler, problem is it's a catch all, not specifically for JBO-26061. Can you think of a way I can tailor fit it for JBO-26061 with a custom message "Database down"?
In addition the exception handler is not consistently called. As example, if you're moving between pages rather than operating on 1 page, the standard af:messages error dialog is shown if the db connection has been dropped, rather than navigating to the exception handler page. As such it seems the DCErrorHandlerImpl.reportExceptions is the better chokepoint to work from.
Cheers,
CM.

Connection error while provisioning to AD in SSL mode

Hi all,
I am trying to establish the OIM-AD communication in SSL mode to provision the passwords.
for that i used the MSFT_AD_base_91100 connector and deployed it on my OIM-9101which is on Win Server 2003
I configured the ITResource by specifying the following details.
use SSL: yes allow password provisioning: yes port:636
and i imported the keystore by executing 'keytool' command at \bea\jdk....\jre\... keytool.exe
but when i am trying to provision the user by using this SSL mode configuration i am getting the error "Error encountered while connecting to target system". and in the logs i am getting the following exception
=========================================================
ERROR,25 Mar 2010 03:40:49,812,[OIMCP.ADCS],com.thortech.xl.integration.ActiveDi
rectory.tcUtilADTasks : createUser
ERROR,25 Mar 2010 03:40:49,812,[OIMCP.ADCS],Connection Error Occur

ERROR,25 Mar 2010 03:40:49,812,[OIMCP.ADCS],com.thortech.xl.exception.Connection
Exception: Connection Error Occur
==========================================================
Note: 1) checked AD in SSL mode through jxplorer and ldapbrowser and it is connecting in SSL mode.
2) checked by provisioning the user in non-ssl mode using this connector and its working fine.
Could anyone help me in resolving the issue.?????
Thanks in advance.

My suggestion would be - Follow the steps religiously and see if you missed any step or not because I have tried it many a times and other people have also did and it works. You are saying that you imported that certificate in OIM too. See the document and verify your steps and finally the connection parameters in IT resource should be:
- Use SSL = yes
- Port Number = *636*
Thanks

Does any one have idea what could be the reason?

Hello Nageshwar,
the likely root cause of this issue is the lack of permissions for the user on the shadow instance.
Please review note #592514 and check your users' rights accordingly.

LMS4.2.2 TopologyView - sporadic Aniserver connect error

Hello,
As some others in this formun too, I recognized similar Java caused TolpologyView Problems.
But not allways: With all clients in this network including the local IE on LMS server too - sometimes the start of TopologyView is working, sometimes not:
In Failure-Situation: Cannont conect to ANIServer: null, unknown error
I switched also the Windows-Firewall (tuned for all LMS-Apps and DFM with monitoring via logging for blocking connections before) at LMS server off - no changed behaviour. There is no other firewall in between, direct connection - that means Proxy exception set in browser. The problem is the same with IE and Mozilla and also the same with local and ACS remote users. Would be nice if I can switch the Windows-FW on again, because its actually a must from the security department at this customer that the windows firewall is active.
Attached is a screenshot of the error message, status bar of connecting ANI... und the Java-console-log in Failure-Situation.
Need help,
thx, Steffen

Hi Aparada
The LMS is installed in a Windows Server 2008 Enterprise.
I restarted the ANIDbEngine process but I have the issue yet. Also, I see that ANIServer process is in "Running with busy flag set" state. Is this normal?

Web Service Timeout & connection errors

Using jwsdp 2, i have developed a client that has a timeout property set. How are timeouts processed? Is an exception thrown by the port? or does the web method just return with a null return value?
I also have noticed that in simulating a connection error (by stopping my app server) that an exception is thrown by the web method? but the exception is a javax.xml.ws.WebServiceException. How do I distinguish connection errors from other exceptions? what other exceptions are there?
Basically, where is this info documented?

Hello Vipul
Enter the RZ10 and validates the TIMEOUT value of parameter "icm/server_port_<x>" for PROT=HTTP and PROT=HTTPS.
For example, the HTTP service is on port 0 and TIMEOUT=600 seconds
icm/server_port_0 = PROT=HTTP,PORT=80$$,PROCTIMEOUT=600,TIMEOUT=600
in your case, increasing the TIMEOUT and validates the WS again

Fatal NI connect error 12170 issue

Hi guys,
I posted this issue a while back, but go no response, so just hoping for some more feedback. In my alert log, I constantly receive this error:

One of metalinks suggestions is to set DIAG_ADR_ENABLED =OFF. My question is, will that really help and what really is the effect to turning that parameter off????
I usually have 150 users connected at a time to the database, and i am hearing there are a lot of time outs out there in the field...Not sure how to go about diagnosing this......The users are connecting via webservers and dmz so also not sure if i should be looking into setting up Connection Manager. Any help will be appreciated...

Sorry I took forever to reply to this....I went out on vacation and just got back....I think this IP is associated with a Virtual Setup....
The weird thing is, alot of the systems which were accessing the database just fine are now receiving timeouts...Nothing has changed in the database setup...Right now I am getting this error from another application: "null     Io exception: Connection reset" Not sure how to tackle this situation.

After Server running for a period of time, get Connection Errors

Hi All,
We're experiencing some serious issues during performance testing.
Its only occurring with WebLogic 10.3 and only occurring with connections of type oracle.jdbc.driver.OracleConnection.
After a good while testing, the server fills up with the following exceptions....
<09-Oct-2009 15:34:17 o'clock IST> <Warning> <JDBC> <BEA-001129> <Received exception while creating connection for pool "jdbc/sdoPool": Io exception: The Network Adapter could not establish the connection>
Here is the configuration of the jdbc/sdoPool :
Driver Class Name: oracle.jdbc.OracleDriver
Properties -->
user=SOL_ISMART_USER
class=oracle.jdbc.pool.OracleConnectionCacheImpl
protocol=thin
Initial Capacity: 1
Maximum Capacity: 100
Capacity Increment: 1
Remove Infected Connections Enabled
Code to get Connection....
DataSource dataSource = null;
try
dataSource = (DataSource) ctxt.lookup( "java:comp/env/jdbc/"+poolName );
catch ( NamingException ne )
dataSource = (DataSource) ctxt.lookup( poolName );
Connection conn = dataSource.getConnection();
OracleConnection vendorConn = (OracleConnection)((WLConnection)conn).getVendorConnection();
vendorConn.setClientData( "LOGICAL_CONNECTION", conn );
return vendorConn;
Here is my code to close the connection.....
if ( con instanceof OracleConnection )
if ( ( (OracleConnection) con ).getClientData( C_LOGICAL_CONNECTION ) != null )
Connection logicalCon = (Connection) ( (OracleConnection) con ).getClientData( C_LOGICAL_CONNECTION );
// release connection - defense against connection leaking
( (OracleConnection) con ).setClientData(C_LOGICAL_CONNECTION, new Object());
logicalCon.close();
logicalCon = null;
con = null;
else
con = null;
else
if ( !con.isClosed() )
con.close();
Any advice / help greatly appreciated.
Ronan

The issue did seem to reduce when the initial connections were increased and the error also became less frequent when the login delay was implemented.
However, since my code is generating Maps the connection was being used to determine the orientation of the North arrow on the map for the particular view ... The ultimate solution was to remove the render-time database connection and calculate the orientation angle in code.
Thanks,
Ronan

Jdbcodbc connection error

When I am trying to access the database using JDBC ODBC driver from webdynpro I am getting connection error. The following code I am using to get the connection for the database
public java.sql.Connection getConnection( )
//@@begin getConnection()
Connection conn = null;
try {
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
conn= DriverManager.getConnection("jdbc:odbc:PrimaveraSDK","admin", "admin");
catch (ClassNotFoundException e) {
e.printStackTrace();
catch (SQLException e) {
e.printStackTrace();
return conn;
//@@end
I am getting connection is null error. When I am trying to access the same in the standalone application I am able to connect with the database. But in webdynpro I am getting connection null error. Kindly let me know how to resolve this issue.
Thanks,
Regards,
Balamurugan (Bala)

First, bug reports can be made at http://metalink.oracle.com, but you'll need a support contract.
Second, does the bug reproduce if you use one of the Oracle JDBC drivers? Using the JDBC-ODBC bridge is a really bad idea when the OCI and thin drivers are available.

Creating connection error?

hey all, i have created an application which when run through eclipse works 100% as expected. but when exported as a .jar i recieve an error from conecting to the database in question.
String URL = "jdbc:mysql://82.110.105.79:3306/web79-j-clarkhou", username = "*****", password = "********";
               try {
                    Class.forName("com.mysql.jdbc.Driver").newInstance();
                    con = DriverManager.getConnection(URL, username, password);i have narrowed it down to the above 3 lines, the URL string is 100% correct so im guessing its either not finding my driver or cannot create the connection help please ?

I will gladly show you the code nested between them two areas, but i can assure you that the code is never reached. the application does not even make the connection. i have manually tested this by printing out after every command as it wasnt throwing any error
Connection con = null;
               String URL = "jdbc:mysql://82.110.105.79:3306/web79-j-clarkhou", username = "****", password = "******";

But OIM started and I can able to view the OIM Admin consle.
I need to know why this error came and How to resolve it?
Please try to help me.
Thanks & Regards,
Karthick

Looks like you are using LDAPSync post OIM installation and the encryption on the IT resource was not setup correctly. Follow the steps from MOS Article: 1307549.1 for the solution.
_Cause:_
Encryption of the Directory Server IT Resource data in SVP table was not accomplished.
The fields that are plain text are:
Server URL
Use SSL
Admin Login
Admin Password
Search Base
User Reservation Container
_Solution_
1. Use the following query to find fields with "plain text" values:
select svr.svr_name, spd.spd_field_name, svp.svp_key, svp_field_value
from svp
inner join spd on spd.spd_key = svp.spd_key
inner join svr on svr.svr_key = svp.svr_key
2. Set these plain text values to null after making backup of table.
3. Edit the Directory Server to re-set values.
Expected error at this stage:
-- no "System Error call admin...", but that makes sense since the values in question pertained directly to the Directory Server --
4. Re-entered the values for the IT Resource.
5. Saving the changes and verify that SVP values are now all encrypted.
With correct values and encryption, then users are able to be created.-Bikash

The Network Adapter could not establish the connection Error Code: 17002

Hi,
after upgrade b41 to b49, I get error from subject, without any changes in my app.
This occurs only on Oracle AS, on standalone OC4J application works OK.
I use connection defined in persistence.xml:
<non-jta-data-source>jdbc/MyAppDS</non-jta-data-source>
and can successfully test this connection in Enterprise manager.
Also, I tried all tricks mentioned here:
http://www.websina.com/bugzero/kb/oracle-connection.html
I know, that this is JDBC layer problem, but I am sure, that my connection is OK, and
after downgrade to b48 this problem fall away.
Bye,
Lumir

How have you deployed your application exactly, i.e. what is the structure of your ear. I use standard war for deploy.
Is the DataSource defined in your server, or your application? Defined on server, test on Enterprise manager passed successfully.
Try using a direct JDBC connection in your persistence.xml (driver/url), does this work?Not work, this same exception.
How do you access your entity manager? (managed, non-managed, jta, non-jta?)non-managed, non-jta.
FYI, I make downgrade to build 48, and this works - it is last version without this problem.
I added some tracing code to my SessionCustomizer:customize():
DatabaseLogin login = session.getLogin();
logger.fine("URL is :" + login.getDatabaseURL());
With build 48, connection defined using toplink.jdbc.* , the output is:

SQLException: found null connection context

Using JDeveloper, I set up a connection with success. However, running the program generates the following error:
java.sql.SQLException: found null connection context
The error persists even when I use [contextNameFromtheConnection] with #sql{...};
Thanks for your time.
null

You need to set your connection at runtime in your program. For example, to set the default connection:
oracle.sqlj.runtime.Oracle.connect("jdbc:oracle:thin:@localhost:1521:orcl","scott","tiger");
Or, if you have created a JDBC connection conn you could reuse that as follows.
oracle.sqlj.runtime.Oracle.connect(conn);
Hope this helps. -- Ekkehard
