Oracle connect

I got some issues of connecting with an Oracle database. Here's the code related to that:
import java.sql.*;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@142.226.242.207:1521:FMP2","cms","cms");
Statement stat = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stat.executeQuery("SELECT * FROM LOGIN");
I use JBuilder 7. I have already added the appropriate class to my project but my server (Apache tomcat) doesn't recognize the OracleDriver() method.
Can somebody help me please!!!
Jay

And did you read the explicit instructions that come with tomcat explaining where to install the oracle driver?

Oracle Connection Pool failure in COM+

I am having some trouble trying to get a specific database to work with an application that makes use of a COM+ Application. When we point the application at the UAT database everything seems fine, but when we point it to the production database after a few successful calls it ends up failing at the COM+ application recycles.

Not being an expert in Oracle, I have been able to dig up a little bit of information that might be of use ...
a) Our tnsnames.ora indicates that the connections are to be DEDICATED and running Toad bares this out -- dllhost ends up with a single connection.
b) most of the database initial set of parameters seem to be very similar. The only difference I noticed was that the archive log mode and db_cache_advice are ON for production.
c) We have little control over how the connection strings are being created internally in this COM+ application, but however they are created it works for UAT and doesn't for PROD.
d) When we go into our web application and hit a page that makes use of the COM+ component to render, it will work the first time but when I do a simple browser refresh it will usually fail on the 2nd or 3rd time. Almost like it is trying to expand the connection pool size and the oracle server is throwing up.
If I didn't mention earlier the two database instances run on different servers but the application server is exactly the same. We only change the alias we are using for the database (both are defined in tnsnames) and the password used to make its connection.
Does anyone have any clues on this one? I am really spinning my wheels trying to figure out what could cause this type of situation. Anything at all would be very helpful.

It appeared to us that the problem was with the Oracle server and that it might have been failing when we were trying to expand our application connection pool size or basically obtain more connections.
The biggest indicator of this is that we run the same application code against two different databases and one works and one does not work. Having said this, I suppose the problem could be rooted in a data error instead of an oracle server error ...
Is there a specific trace file on the oracle server that would help me point to any error that is truly an oracle server error? Sorry I am very new to Oracle.

Crystal report - and oracle connections

hi to everyone
i installed client of oracle
and after that - the crystal report 2008 sp3
when i open new (blank page) - and looking for a oracle connection
its look like he doesnt exist.
please if someone know why i cant see the connection to oracle/
yossi bar

Hello,
CR looks for the Oracle \bin folder in the PATH statement. If it can't find it then the option to select Oracle native driver will not show.
Thank you

Oracle Connection Manager

Hi,
i'm having a problem configuring Oracle Connection Manager. It does start the instance of connection manager
Summary of my environment is
10g Application server and infrastructure machine OS: Windows 2003
9i Database Server: Windows 2003
Client : Java Applet
JDBC driver type : THIN
Installed: 10g Infra first and then 10g midiier(portal and wireless) in seperate oracle homes on the same machine. Eveything is up and running as i was able to login seperately in infra and midtier enterprise managers.
Final Goal : Trying to connect to an Oracle 9i database on a differnt machine than the appserver using an applet, thin drivers and Oracle Connection Manager
Problem : Connection manager instance not started however cmanADMIn service started.
CMCTL:CMAN_oracle9-app> administer cmanOracleAS
Current instance cmanOracleAS is not yet started
Connections refer to (address=(protocol=tcp)(host=10.10.1.101)(port=1610)).
The command completed successfully.
CMCTL:cmanOracleAS> startup
Service Oracleoracle_infraCMAdmincmanOracleAS already running.
TNS-04012: Unable to start Oracle Connection Manager instance.
CMCTL:cmanOracleAS>
Steps done to configure Oracle Connection manager
1. Copied 4 .exe (CMADMIN, CMCTL,CMGW,CMMIGR) files to bin folder of Appserver or midtier's main ORACLE_HOME/BIN folder.
2) created a cman.ora file and copied in appservers /NETWORK/ADMIN directory
3) On cammand prompt type CMCTL...ADMINISTER cman_OracleAS where cman_OracleAS is the name of cman instance used in cman.ora file.

PHP & ORACLE Connectivity on Solaris

Hi all,
You can check this site for PHP and Oracle connection tutorial. It is intended to installing Apache and PHP with Oracle support and connecting and using Oracle via PHP.
Page URL :
http://gokmen.selcuk.edu.tr/tutor/orasol/ociphp.php
Additionally, You will see an alternative way escaping from ORA-12154 and ORA-12545 errors while Oracle connection via PHP.
Hope you find useful...

Hello,
My developers have changed all the API´s to OCI8 and the code is able to connect with oracle 10g with php4 but, i am still getting this warning .i.e
Warning: ocifreestatement(): supplied argument is not a valid OCI8-Statement resource in /apache/htdocs/English/tender_list.php on line 340
i am unable to figure it out, every thing is working fine but still i am getting it ?
thanks

Php, oracle connectivity.

Hello All,
I have a webserver that has php4,apache1.3 and oci8 instant client installed, and have a seperate oracle 10g db server, the php-oracle connectivity is fine when i run php code from db server but it gives me connectivity error when it runs from web server, error " ocifreestatement(): supplied argument is not a valid OCI8-Statement resource in /apache/htdocs/.....php on line..." while even when i made telnet to my db server 1521 port from web server it shows that listener is working, any idea ? thanks

Certificates in lieu of Oracle connection Manager for our Applets -- Help!!

I support an application named IDEA out of New York. The IDEA application is an INTRANET application for use within our company Firewall.
Currently, the IDEA application's front end resides on a Windows 2000 Server running IIS 5 and JRun 3.0. The back-end runs on Oracle 8.1.7 database on a UNIX Database Hosting Utility (DHU). Our applets communicate with the back-end database using Oracle Connection Manager that is installed on the Web Host.
We are trying to migrate to the DWeb environment (Linux cluster). The linux cluster is running Apache Tomcat. We have been told that installing Oracle connection manager is not a viable solution (our company does not support it). Because of this our applets cannot communicate with our database. Below is a brief description of this limitation and also the work-around.
====================================================================================================================================================
Connecting to the Database through the Applet
The most common task of an applet using the JDBC driver is to connect to and query a database. Because of applet security restrictions, unless particular steps are taken an applet can open TCP/IP sockets only to the host from which it was downloaded (this is the host on which the Web server is running). This means that without these steps, your applet can connect only to a database that is running on the same host as the Web server.
If your database and Web server are running on the same host, then there is no issue and no special steps are required. You can connect to the database as you would from an application.
As with connecting from an application, there are two ways in which you can specify the connection information to the driver. You can provide it in the form of host:port:sid or in the form of a TNS keyword-value syntax.
For example, if the database to which you want to connect resides on host prodHost, at port 1521, and SID ORCL, and you want to connect with user name scott with password tiger, then use either of the two following connect strings:
using host:port:sid syntax:
String connString="jdbc:oracle:thin:@prodHost:1521:ORCL";
conn = DriverManager.getConnection(connString, "scott", "tiger");
using TNS keyword-value syntax:
String connString = "jdbc:oracle:thin:@(description=(address_list=
(address=(protocol=tcp)(port=1521)(host=prodHost)))
(connect_data=(sid=ORCL)))";
conn = DriverManager.getConnection(connString, "scott", "tiger");
If you use the TNS keyword-value pair to specify the connection information to the JDBC Thin driver, then you must declare the protocol as TCP.
However, a Web server and an Oracle database server both require many resources; you seldom find both servers running on the same machine. Usually, your applet connects to a database on a host other than the one on which the Web server runs. There are two possible ways in which you can work around the security restriction:
You can connect to the database by using the Oracle8 Connection Manager.
or:
You can use a signed applet to connect to the database directly.
These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
Connecting to a Database on a Different Host Than the Web Server
If you are connecting to a database on a host other than the one on which the Web server is running, then you must overcome applet security restrictions. You can do this by using either the Oracle8 Connection Manager or signed applets. ====================================================================================================================================================
It was suggested that we implement signed applets (it is our only alternative at this time). This is where, hopefully, you can help me. We are unfamiliar with using certificates and signing applets. We need to obtain certificates that will allow our applets to connect to our oracle database on the DHU. What kind of certificates do we use? Are their coding examples of how to use these certificates? We have a CA within our company but they cannot tell us what kind of certificates we need. How many certificates do we need? Do we install any certificates on the backend database server? Any information would be greatly appreciated. We are basically trying to get our applet to work outside the sandbox by establishing a connection to the database server.Thanks in advance for your time.

or:
You can use a signed applet to connect to the database directly.
These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
If you want to connect to the database from the applet there is a third option.
Since this is an intranet application you have control over the desktops using this
application. In our company the jre ignores signed applets (as it should) because
it gives control to the user to run potentially harmfull applets from the Internet.
The way to dish out special privileges to applets is the policy, put a policy file on
you intranet and have the jre use it by specifying its URL in the java.security.
Here is some more info about security configuration of the jre:

We use Oracle jinitiator to run Oracle forms but I am not involved in that project
and do not know a lot about it. It does perform quite good though.

If you use the TNS keyword-value pair to specify the connection information to the JDBC Thin driver, then you must declare the protocol as TCP.
However, a Web server and an Oracle database server both require many resources; you seldom find both servers running on the same machine. Usually, your applet connects to a database on a host other than the one on which the Web server runs. There are two possible ways in which you can work around the security restriction:
You can connect to the database by using the Oracle8 Connection Manager.
or:
You can use a signed applet to connect to the database directly.
These options are discussed in the next section, "Connecting to a Database on a Different Host Than the Web Server".
Connecting to a Database on a Different Host Than the Web Server
If you are connecting to a database on a host other than the one on which the Web server is running, then you must overcome applet security restrictions. You can do this by using either the Oracle8 Connection Manager or signed applets. ====================================================================================================================================================
It was suggested that we implement signed applets (it is our only alternative at this time). This is where, hopefully, you can help me. We are unfamiliar with using certificates and signing applets. We need to obtain certificates that will allow our applets to connect to our oracle database on the DHU. What kind of certificates do we use? Are their coding examples of how to use these certificates? We have a CA within our company but they cannot tell us what kind of certificates we need. How many certificates do we need? Do we install any certificates on the backend database server? Any information would be greatly appreciated. We are basically trying to get our applet to work outside the sandbox by establishing a connection to the database server.
Thanks in advance for your time.

Eston,
Have you searched SUN's java Web site? Maybe this article will help:

CSV to Oracle - (Integration) fails on the target ORACLE connection

Hi,
I am trying to load data from a csv file into Oracle db via ODI.
Here are the steps i followed:
1- Created the FILE physical schema
1- Created the Oracle data server and physical schema in Physical Architecture
2- Created and linked to logical schemas
3- Created the correspondent data models and stores and a
ble to view the data contents of the CSV and of the target table in ODI.
4- Created interface, added csv as source and oracle table as target
5- Used "LKM File to SQL" and "IKM SQL Control Append" (FLOW_CONTROL is false)
When i execute the interface, the session starts then i receive the following wrror in Operator:
ODI-1228: Task ARIBA_G1 (Integration) fails on the target ORACLE connection DEV_DW.

Hi Santy,
No, no error or bad files.
Actually the data are moved correctly into the temp table created by ODI, but not from there to the final target table.
I found out the reason though, the knowledge modules imported were from another ODI installation!
I made sure to import the proper KM and it worked.
Thanks!

Creating an Oracle connection in Net WCF using ODAC causes Exception

Why am I getting a 'System.TypeInitializationException' when I create an Oracle connection in my .Net WCF web service?
=========================================================================
I'm currently working on implementing a WCF service which talks to an Oracle 10g database on the backend. When I attempt to connect to the database from within my service, I get the following exception: System.TypeInitializationException.
•I'm running on a windows 7 (64 bit machine).
•I'm using VS 2010.
•I'm using Oracle 10g on the backend.
I'm the Oracle.DataAccess.dll (ODP.Net) from the following installed instance
c:\oracle\product\10.2.0\.....\ODP.NET\bin\1.x\Oracle.DataAccess.dll
•I've included this DLL in the references for my WCF service.
•I've included this service as a project within my VS WPF solution.
•The service starts up automatically when I start my WPF application in VS 2010.
At runtime I see the following output in my debug output window:
'WcfSvcHost.exe' (Managed (v4.0.30319)): Loaded 'C:\Windows\assembly\GAC\Oracle.DataAccess\1.102.2.20__89b483f429c47342\Oracle.DataAccess.dll' A first chance exception of type 'System.TypeInitializationException' occurred in Oracle.DataAccess.dll
Sure enough, I look at the exception details in the debugger and I see the following information (this occurs when I attempt to create a new ORACLE connection):
"The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception." InnerException {"The provider is not compatible with the version of Oracle client"} System.Exception {Oracle.DataAccess.Client.OracleException}
A Little Background:
I'm basically migrating my data layer to a WCF service. The same service layer previously existed in a WinForm application. Everything works fine in my WinForm application. I include the same reference to the Oracle.DataAccess.dll and all my reads/writes with the database work fine.
Is there something obviously different between the WCF and WinForm access/use of the DLL? Is there some limitation I'm unaware of? Is there an issue running this through VS2010 in the debugger?
I have absolutely no idea what is going on here. Any hints/direction would be greatly appreciated.

It's certainly possible to install .NET 1.x on the machine while still using VS 2010, but MS does not support and most likely never tested this combination. Running .NET Framework 1.x on Windows 7 also is not supported. I didn't know you had successfully used this combination previously. Nonetheless, it's good to be on a supported combination that has been certified by MS and Oracle if you run into a problem.
I had another reason to ask you to upgrade to ODP.NET 11.2 As it will be the last version installed, ODP.NET's unmanaged DLLs will appear in your PATH first. The error you see is typical when ODP.NET from one version tries to use DLLs from another Oracle instance installed on your machine.
If that doesn't work, set the DllPath setting in your web.config file to the BIN directory of your newly installed Oracle Client. Here's an example of that:
http://docs.oracle.com/cd/E20434_01/doc/win.112/e23174/featConfig.htm#sthref109

How to install oracle connection manager on solaris 10

I have installed oracle application server 10.1.2 on solaris 10. How do i install oracle connection manager utility.
My end goal is to use applets/jdbc.
Thanks

Thank you Zettabyte!!
Folks, network printers should NOT BE configured like this:
lpadmin -p somequeue -s someprinter
that creates a remote style queue and puts all the I/O and processing capability on the basic LPD listener present on network printer interfaces. This will cause problems down the road, not to mention that you cannot control access, get any logging, filter content, or control banner pages.
Network printers should use any software (or PPD file) supplied by the vendor over the basic lpadmin/netstandard config.
You can install CUPS, but Oracle won't support it until it's part of the OS (S11, apparently).
The "System Administration Guide: Solaris Printing" is highly recommended for those administering printers on Solaris.

Help me about oracle connect poo in wls5.1l!!

Help!
I can not create oracle connection pool using the following
directive in my weblogic.properties of wls5.1:
weblogic.jdbc.connectionPool.oraclePool=\
url=jdbc:oracle:thin:@oracle.myserver.com:1521:mydb,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=1,\
maxCapacity=10,\
capacityIncrement=1,\
allowShrinking=true,\
shrinkPeriodMins=15,\
refreshMinutes=10,\
testTable=house_dict,\
props=user=system;password=******;server=mydb
But I can connect to the database in my servlet/jsp using oracle:thin
connect method, Why???
The library I used is oracle's classes111.zip
Help me please!!!!

Remove the ';server=mydb' from the props.
It would help if you included the error message from the weblogic log file.

RE: (forte-users) Forte not letting go of Oracle connections+ RE: (fort

The bug was just reported yesterday so they might not have it available to
the public for a while. I am guessing this bug has been around since 3.M.?
and its very easy to verify it if its happening in your environment. Also I
have been talking to other user that are not using Oracle (Sybase instead)
who are also seen the same problem. I think this is a problem across all
database because there is some fundamental event or process that is not
taking place to close database connections. But just to be safe verify it
in your test environment before moving to 3.5. To verify if its happening
in your Forte version just create a small application that connects to the
database and run it in debug mode. Log into the database and then stop the
debug session. The connection will still be open. This will also occur
when you use the running man or in a deployed application.

Hi Kamran,
I just looked up bug # 54610 in Cyber Support and it is not there yet, so a
question.
In your opinion, does this effect all databases? We are using DB2 and
considering going to 3.5 . Are we going to see the same problems you have
had with Oracle?

NotSerializableException when getting an oracle connection thru RMI

Hi all,
I have been trying to access my oracle connections , which are part of a pool, using rmi.
I have encountered following exception -
java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.io.WriteAbortedException: Writing aborted by exception; java.io.NotSerializableException: oracle.jdbc.drive r.OracleConnection java.io.WriteAbortedException: Writing aborted by exception; java.io.NotSerializableException: oracle.jdbc.driver.Oracle Connection
Is there any reason for OracleConnection not to be serialized or am i doing something wrong?
Any help in this regard is urgently solicited
regards

Just tell your DBA to act like a professional and not shut the server down without notifying the user community! That is one of the top pet peeves of any user to have the carpet jerked out from under him!! All shutdowns should be scheduled unless the machine fails or the world ends...
Otherwise you will have to look for some method to re-verify the connection again. i don't think that the driver will automatically tell you if the connection got jerked away. It will probably think it is still connected!
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Justin Poyser ([email protected]):
How do I check if the DBA has bounced the database ? I have the following check to determine if the connection is available
if (conn == null | | conn.isClosed())
but it still seems to return false for conn.isClosed.
thus when you run a sql statement against the returned connection object you get a no more data to read from socket error.<HR></BLOCKQUOTE>
