Database connection problem in Oracle 8.1.6

Hi,
I have a program which was written in C++ and Pro*C for UNIX. I didn't use runtime context for database connection.The program runs ok under Oracle 8.0.4. When compiled and run under Oracle 8.1.6 I got a "libc internal error - _rmutex_unlock not held" error. This error occurs only when "EXEC SQL CONNECT :loginName " is called.
I wonder if we always have to create a runtime context for connection under Oracle 8.1.6 ?
Thanks in advance for your help.
Harry

I had the same symptom from a multithreaded C++ application
until I added the -mt option to the CC command when linking.
You are supposed to use it for compiling, too.

Database Connection problem (JSP, Oracle & Tomcat 5.5)

I am trying connect to Oracle 8 database through JSP and the webserver is Tomcat5.5. The classes.jar file is in the Tomcat5.5\common\lib directory and the path has also been set to mentioned directory. But I am getting exceptions. The code and the error are given below.
Need help at the earliest.
Thanks in advance.

hi,
FIrst make one thing clear. By classes.jar you mean either classes111.jar or classes12.jar.Right?If not,please check tht.
Also,u needn't set any classpaths for Tomcat.

Database connection problem in oracle sql developer kit?

Status : Failure -Test failed: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

Hi,
You have to check the service_name in the tnsnames.ora file located in the oracle installed folder.
Check one more whether the services are up or not.

Connection problem to Oracle 11.1.0 on Windows Professional XP (SP2)

Hello
I've recently performed default installations for 3 Oracle Databases, into seperate homes on a newly formatted Windows
Professional XP (SP2) standalone laptop. For all databases Oracle 10.2.0 (rover), Oracle XE (xe) and Oracle 11.1.0 (fido) I
installed APEX and they worked perfectly.
I then installed my Wireless O2 Broadband for my internet which uses DHCP
I am unable to connect to my databases with the wireless broadband connected. I then bring down all databases and turn
off/disable the Broadband,then restart all databases.
Using commands
Set ORACLE_SID=ROVER
sqlplus system/rover@rover
Set ORACLE_SID=XE
sqlplus system/xe@xe
Set ORACLE_SID=FIDO
sqlplus system/fido@fido
Connections are successfull apart from the Oracle 11.1.0 (fido) database with error
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
Can anybody identify my connection problem to Oracle 11.1.0 (fido) database by reviewing my listener.ora, tnsnames.ora and
other configuration files below.
Many thanks in advance
Regards
Ade

Immediate HELP in Tomcat 5 to Postgresql 7.4 database connectivity problem

Hi,
I failed to connect Tomcat 5.0.24 with Postgresql
7.4.2. The files created by me and the changes i had
made in the existing files are rates.jsp,
conversionDAO.java, web.xml and server.xml. The error
message on the top of the rest of it was "The value of
useBean class attribute converter.conversionDAO is
invalid". So far I found out that the coding for
database connectivity purpose in conversionDAO.java
cause the error. Another thing is Postgresql jdbc
driver is required to set in the CLASSPATH for the
java file to access the Postgresql database. I don't
know where should I put it in Tomcat for web
application. Anyway, I put it in
$CATALINA_HOME/shared/lib according the book i
refered. I do the database connectivity coding refer
to the Tomcat Kick Start book from Sams Publishing.
Below are the coding involved, please show me the
mistake i had made. Thank you.

Database connection problem when i try store the values in JTable

Hi Sir,
I have a database connection problem when i try to store the data's in a JTable.I think the problem is with in the database connection.I have used 3 vectors here.The database which i have used is
Access.Where the program is compiling well.But when i run it only the first column heading is printed and error message showing that
"Invalid Cursor State".I need to solve this problem.pls. do help me.
I will provide u with the code.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
import java.util.*;
import java.sql.*;
public class DataBaseVector extends JPanel
//Container contentPane=getContentPane();
JScrollBar jsb = new JScrollBar(JScrollBar.HORIZONTAL);
JScrollBar jsb1 = new JScrollBar(JScrollBar.VERTICAL);
Image i1;
String url="jdbc:odbc:Ananth";
Vector col=new Vector();
Vector rows=new Vector();
Vector rdata=new Vector();
Connection conn;
public DataBaseVector()
//super("JTable With ScrollBars");
this.setLayout(new BorderLayout());
UIManager.put("ScrollBar.track",Color.red);
UIManager.put("ScrollBar.thumb",Color.blue);
try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn=DriverManager.getConnection(url); // Is there any problem here?
Statement st=conn.createStatement();
ResultSet rs=st.executeQuery("Select * from AccountMaster");
// rs is the result set obtained
ResultSetMetaData rsmd=rs.getMetaData();
int cols=rsmd.getColumnCount();
for(int i=1;i<=cols;i++)
col.addElement(rsmd.getColumnName(i));
rdata.addElement(rs.getString(i));
rows.addElement(rdata);
}catch(Exception e)
 System.out.println("The Error Message was:"+e.getMessage());
JTable jt=new JTable(rows,col);
int v=ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED;
int h=ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED;
JScrollPane jsp=new JScrollPane(jt,v,h);
this.add(jsp,BorderLayout.CENTER);
this.add(jsb, BorderLayout.SOUTH);
this.add(jsb1, BorderLayout.EAST);
public static void main(String args[])
JFrame jf=new JFrame();
JPanel frame=new DataBaseVector();
jf.getContentPane().add(frame);
jf.setSize(800,600);
jf.setVisible(true);
Thanx,
m.ananthu

The problem is ResultSet.next() is not called.
Try this and modify the table creation as you need.
ResultSetMetaData rsmd=rs.getMetaData();
int cols=rsmd.getColumnCount();
 while(rs.next()) {
 for(int i=1;i<=cols;i++)
 col.addElement(rsmd.getColumnName(i));
 rdata.addElement(rs.getString(i));
 rows.addElement(rdata);
Hope this helps

Can anybody guide me what can be the problem asap.

Ramesh,
This looks like it might be a Java class mismatch error. Do you have multiple versions of Java installed on your machine? If so, you may want to keep one version and remove the rest.
If you're already running just one version, you may want to check the registry and classpath for references to multiple Java versions, or version that no longer exist.
Please let me know if you have additional questions.

Too many inactive database connections (c#, webapp, Oracle)

 I have a web application that uses the CrystalDecisions.Web.CrystalReportViewer to display my reports. The application opens a connection to an Oracle database with SetDatabaseLogon(). I have not yet implemented anything to free the connections when they're not needed anymore. I read in the Crystal help that the best place to call ReportDocument.Close() is in the Page_Unload method.The problem is that my reports have dynamic cascading parameters that make the page reload (ie Page_Unload -> Page_Load) several times. I can eventually call ReportDocument.Close() in a Global.asax method, like Session_End(), but I'm not sure it is optimal, as my report object is not known in this scope and I have extra code to write to handle this. Is there a better way to manage database connection ? Can anyone provide a working sample ?thanks 

I'm not aware of a better way. Your connections are definately being held up because you are not closing the Report. Possibly you could put a conditional ReportDocument.close() call in your unload method. You would need to check to make sure that the document was available and that you weren't loading parameters. I'm sure that this would work. Rob Horne<a href="/blog/10">Rob's blog - http://diamond.businessobjects.com/blog/10</a>

Sun One application server connection problem for Oracle DB

On our project in live environments we have six Sun One application servers that have been configured to connect to RAC Oracle database using OCI drivers. ( JDBC thick driver)
Sun one application server : Version 7.0.0
Oracle Database : Version 9.2.0.4.0
Following are two scenarios where Sun one server receives an error while attempting to perform any DML operations onto the database e.g. when you will try to send a insert/update msg through sun One.
Case 1: - If the Oracle package/procedure/function is compiled using �Alter package/function/procedure....� command
problem
Any attempt to perform a DML operation using RMI calls though Sun one application server with already established oracle connection will fail.
Sun One application server needs to be bounced to get an up-to-date state of the package.
Case 2: If the Oracle package/procedure/function is compiled using �Create or Replace package/function/procedure....� command
problem
First attempt to perform any DML operation using RMI calls though Sun one application server with already established oracle connection will always fail. Any subsequent attempts will be successful.
We are using JDBC OCI think drivers. I tried flushing Shared pool at the Oracle side but it didn't help. For some reason Sun One seems to Cache the session information for already establised connections with Oracle database. As its live system we don't want any outage. i.e we know bouncing oracle app server will solve the problem.
So just wondering is there way/workaround to make aware the already estlised connection from sun one appserver to Oracle DB about changed packages/proceduress in the DB?
Any thoughts on this would be much appreciated.

Forgot one thing: when I use remote debugging , it works.

These days I very seldom use ODBC for Oracle - most recently it was simply to get Enterprise Architect to "talk" to Oracle. I never used it for my client applications (unlike in the fast distant past), so what I know about ODBC is seriously outdated.
Even so, a few comments. :-)
Have you tried creating a user DSN, in case a system DSN somehow works different environment wise?
The above error description sounds like the original TCP connection was successful (i.e. it is not a host unknown or not reachable error). Subsequent packets seem to fails.
To confirm, run the listener on namesrv1.xy.zz.com with logging enabled and have a look at the listener.log - does it show a connection being accepted/handled from your PC when you use the ODBC DSN?
Have you tried the Oracle ODBC drivers? When getting EA connected I had problems (also with Instant Client) and Microsoft ODBC driver for Oracle. Downloaded and installed the Oracle ODBC driver and it worked just fine first time around.
PS. You should raise this topic on the Instant Client Forum instead.

Database Connection Problem on Linux

I have recently installed Oracle Database on a linux server. The app server that accesses db is JBoss.
Always, I end up seeing an error "java.sql.SQLException: No more data to read from socket".
To verify if the problem is with JBoss, I have written a simple stand alone java class to access the db, and ended up with the same error.
Can anybody help me out ??
-Aswin.

This error most likely occurs in applications that
use a database connections pool. When the application
checked out a connection that has been timed out or
has been staled, and used it to connect to the
database, this error occurs.
Could also be a result of connection timeout.Yeah! may be it is the result of connection timeout, but I am sure it cannot be realted to connection pool, because to verify if there were any configuration problems on JBoss, we have written a simple java class that directly accesses the database.
If it is because of connection timeout, how do i fix it ??

Database connection problem SQL Error: 20, SQLState: 61000

we are doing stress test on our new web site that uses vaadin framework and hibernate. Our application/web server is apache tomcat and maximum thread number is adjusted to 750.
we are using jmeter for stress test and when we send 500 user scenario (approximately 15 - 20 database connection per user) in 30 seconds
we are encountered the following error:
*14:43:10,502 WARN JDBCExceptionReporter:233 - SQL Error: 20, SQLState: 61000*
*14:43:10,503 ERROR JDBCExceptionReporter:234 - The Network Adapter could not establish the connection*
but if we send 500 user in 45 seconds there is no problem, jmeter test is completed with 100% success. even if we send 900 user in 120 or 180 second it is OK.
it seems that there is a DB related parameter that we could not handle properly or maybe operating system limitation (windows 2008 R2).
any help will be appreciated. thanks in advance.

It's the DBMS. Oracle particularly can react this way when there are too many connection requests
coming in, whether from multiple threads at once, or even from one thread in a tight loop. I do
not know if there's a way to moderate/adjust this. I typically recommend using connection-pooling,
and to do as much as possible to populate the pool before there is application load.

Thank you for the replies
The problem got solved. Problem was older version of Oracle driver was placed in WEB-INF/lib and a directory called lbrary(we created it) above WEB-INF, we were placed newer version of driver in oracle's jdbc/lib directory and specified that path in classpath. But by default the older version was prioritized and used by application so we were getting the exception mentioned. When we deleted older version of driver everything got working. This explation may help for those who have similar type of problems.
Thanks

Database Connection Problem via a Windows Form

I am having a problem getting a database connection using a windows form. The strange thing is I can use the same connection string in the sister web application and the database connection works perfectly fine.
I am using:
.NET 1.1
ODP.NET 9.2.0.700
Oracle 9i PatchSet 11
Here is an example of the connection string:
_oraConnStringMain = "Data Source=mydb;User Id=myid;Password=mypass"
The error is: "ORA-12154: TNS:could not resolve service name" and remember the same connection string and implementation is the web application works fine.
Offending code:
          public bool ValidateOracleConnection(string connectionString)
               bool _success = false;
               OracleConnection oraConn = new OracleConnection(connectionString);
               try
                    oraConn.Open();
                    _success = true;
               catch (Exception ex)
                    MessageBox.Show(ex.Message.ToString(), "MYAPP", MessageBoxButtons.OK,
                         MessageBoxIcon.Information);
                    _success = false;
               return _success;
Any ideas?

Hi Steven,
My only WAG is that a different sqlnet.ora or tnsnames.ora might be used for the two different apps. Search your machine for both files. Are they only in the OH\network\admin directory?
You may want to run a client side sqlnet trace of both apps, and compare them. It should tell you what tnsnames.ora file it's using, and may give a clue as to why the difference.
Hope that helps,
Greg

Client side connection problems with Oracle

Hello,
I'm using JUnit to test my code and am having client connection problems.
Weblogic server 6.1sp2, oracle 8.1.7, win 2000
I create an oracle user on the fly (with a dynamic name) and then need to connect
so I'm getting a direct connection, rather than using a connection pool.
it works fine when run through the container, but when run through JUnit I get the
following error:
java.sql.SQLException: The pool driver only works within the WebLogic server, it
cannot be called directly in a client. Use the t3 driver.
So i changed the code to:
driver = (Driver)Class.
forName("weblogic.jdbc.t3.Driver").newInstance();
from:
driver = (Driver)Class.
forName("weblogic.jdbc.oci.Driver").newInstance();
and now i get this error:
java.sql.SQLException: No suitable driver
Any ideas??
Thanks!
Sara

Hi Sara,
You may want to look at Cactus framework. This is a JUnit extension
for serverside tests. You won't need to care about server/client
configuration:

Hi Sree,
Actually, I also have a connection pool, so I am getting connections tothe database
both using the pool (for the static user) and directly for the dynamicusers.
>
Here's the code in the config.xml:
<JDBCConnectionPool CapacityIncrement="2"
DriverName="weblogic.jdbc.oci.Driver" InitialCapacity="6"LoginDelaySeconds="1" MaxCapacity="60"
Name="pics"
Properties="weblogic.oci.cacheRows=500;user=**;password=**;defaultRowPrefetc
h=500;server=nmctest"
RefreshMinutes="10" ShrinkPeriodMinutes="15"
ShrinkingEnabled="true" Targets="nmc2Server"
TestTableName="dual" URL="jdbc:weblogic:oracle"/>
<JDBCTxDataSource EnableTwoPhaseCommit="false"
JNDIName="weblogic.jdbc.jts.pics" Name="pics" PoolName="pics"Targets="nmc2Server"/>
>
And if I change the above DriverName to weblogic.jdbc.pool.Driver the poolno longer
works, and the direct connection (attempted with weblogic.jdbc.oci.Driver)does not
work either.
Thanks for your help!
Sara
