Establishing connection to Oracle

Hi all. I've just started with JDBC and Oracle 10g.
In book "Java programming with Oracle Jdbc" they told me to start with adding to CLASSPATH classesXXX.zip.
1) I found Oracle_Home\jdbc\lib\classes12.zip as I understand it is for java 1.2 version, but I am using java 1.6.
2) How to add to classpath file? I am using Eclipse IDE.
Thanks in advance.

Yes, you can get a more modern JDBC driver here:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
2) How to add to classpath file? I am using Eclipse IDE.I haven't used Eclipse in a while, but if I remember correctly you right click on the project root, select "Properties", and add the path to the 3rd party JAR to your CLASSPATH there.

Cannot establish connection with Oracle database

Hello
This is the first time I use BOE server with Crystal Report to execute some tests, and one issue is blocking me now, and I am not even sure if this is the right Forum where I should post it.
I installed BOE server XI 3.1 SP4 on Linux machine (new installation), and then I uploaded some existing Crystal Report templates that are working fine on another BOE server. Those CR templates have to establish a connection with a remote Oracle database to get the data, and we pass all credentials for this purpose.
The first time I run my first test I received this error that I could not find anywhere on the web :
ErrorLog 2011 8 10 7:05:52.505 14215 356 (Administrator:82) (../reporthandler.cpp:12462): CReportHandler::buildReportViewerError: CSResultExceFailed to open the connection." FileName:"../reporthandler.cpp" LineNum:12458 ErrorCode:756 ErrorMsg:"Failed to open the connection.
{FBAD55EE-BEAF-11E0-BC1C-005056813A72}.rpt" DetailedErrorMsg:""
I believe that the CR was not able to establish the connection with Oracle, so I install Oracle Client on the same machine (test remote connection ==> pass), I set the ORACLE_HOME variable, and I edit the file <installation_home>/ bobje/java/CRConfig.xml to add the path to ojdbc14.jar, and finnaly restart the tomcat server. However I am still getting the same error message.
Is there any hint that can help me troubleshooting this issue?
Thank you

do the reports use native oracle connectivity or JDBC ?
what version of Oracle client did you install ?
was it 32bit or 64bit client ?
what your LD_LIBRARY_PATH variable set to ?
what does it say in the CMC when you look at CR report's DB properties ?

Unable to establish connection to oracle database using sql developer

hi guys,
i tried to connect to the oracle database using the sql developer, but it fails. it replies the following message:
Status: Failure -Test failed: Io exception: The Network Adapter could not establish the connection
what should i do? any help

Please provide a little more information:
1) SQLDeveloper version.
2) Database Version.
3) Database location (same machine or on the network).
4) Connection method (basic,TNS).
5) Connection type (Thin,Thick/OCI).
Usually the first thing to check is if you have correctly entered the right information for your database connection, then if everything seems to be OK the database itself should be checked for potential problems.

How to establish connection with oracle........

Hi,
I'm using ODBC driver and
I've given
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection cn=DriverManager.getConnection("jdbc:odbc:mydatabase","scott","tiger");
where mydatabase is the datasource name,scott is the user name,tiger is the password.
while running I got the error as:
java.sql.SQLException:[Oracle][ODBC][Ora]ORA-12560:TNS:protocol adaptor error.
I don't know how to solve this one.
Should I give the "ServiceName" while creating my datasource name............?????
Can anyone help me...........
Thanks in Advance.
Subha.

There are a couple of things that you might need to take into account while using the ODBC. Firstly, you need to set up an ODBC connection to the database. Secondly, you need to have the tnsnames.ora to point to the database the connection info.

Can not establish connection Oracle DB

Hi PI Gurus,
We have a sender JDBC CC, its working absolutely fine in PI dev.
when I check this CC in PI Qality it is giving me error as:
Error during database connection to the database URL 'jdbc:oracle:thin:@204.145.15.141:1521:PERM' using the JDBC driver 'oracle.jdbc.driver.Oracledriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Can not establish connection:: SAPClassNotFoundException: oracle.jdbc.driver.Oracledriver'
It clearly says that driver is not installed, thats why connection is not getting established. Our BASIS team installed the drivers twice copied from Dev systems, still the same error is coming.
Can anyone throw some light on this, is any problem with the version?
Thanks,
Krishna

Hi Krishna,
Can you check two things:
1. whether the host name of the jdbc server u are tryin to access is present in the PI Quality system hosts file
2. Whether connectivity port is correctly opened with the jdbc server, i.e connectivity exists and is tested.
Regards,
Souvik

Slow connection through Oracle ODBC

Hello,
I have problems with connecting to ORACLE fr om IIS (Win2000) using Oracle's ODBC driver.
I am using Oracle 8.1.7 SE. I tried to change connection pooling timeout of the ODBC driver, but still connections time out after a minute or so and it takes 6-8 seconds to load a simple web page that reads only ~ 1 kb of information from ORACLE. The time to establish a connection to MS (Access ,SQL server) is less than a second. How can I establish connections to ORACLE faster?
Please help,
thanks,
Gyorgy

Justin,
thanks for your quick replies.
Using Oracle ODBC 32Bit Test:
the connection seems instantaneous. I tried to enable connection pooling for Oracle ODBC driver with a wait in the pool for 600s. Maybe this will keep it live and I can instantiate a fake connection every 10 minutes? I do not what else I could try ...

I'm curious as to whether you see a difference between connecting via a DSN or through a DSN-less connection string.

Establish SSL connection to Oracle Instance w/JDBC Thin Client

Hello all,
I am writing a monitoring utility that will allow me to establish connections to both Oracle instances and LDAP repositories and query them to determine that they are up and running. My utility consists of a number of objects that handle connections to the LDAP and Oracle instances. I need to be able to do SSL and non-SSL connections to said instances.
My issue is this: I am able to do SSL and non-SSL to LDAP, and non-SSL to an Oracle instance. I am having problems, though, establishing an SSL connection to an Oracle instance (I am using the thin client). Whenever I try, a SQLException is thrown that states: "Encountered a problem with the secret store. Check the wallet location for the presense of an open wallet (cwallet.sso) and ensure that the wallet contains the correct credentials..."
Ok, a little background for those who may need it. Oracle uses a wallet to hold certs that allow SSL connections. I have a wallet on my box, and, from the command line, I am able to sqlplus into and tnsping the appropriate Oracle instances, so I know it is setup properly. The inability to connect only occurs in my code. My code looks like this:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Security.addProvider(new oracle.security.pki.OraclePKIProvider());
/*Setup connection properties*/
String connectionString = "testbox01:1000:ssl_instances_name";
String userName = "userName";
String pwd = "password";
Properties props = new Properties();
props.put("oracle.net.ssl_version", 3.0");
props.put("oracle.net.wallet_location", "SOURCE=(METHOD=file)(METHOD_DATA=(DIRECTORY=c:\\wallet)))");
props.put("oracle.net.ssl_cipher_suites", "ssl cipher suites");
props.put("oracle.net.ssl_server_dn_match", "FALSE");
props.put("oracle.net.ssl_client_authentication", "true");
/*Do connection and return connection object
OracleDataSource ods = new OracleDataSource();
ods.setUser(userName);
ods.setPassword(pwd);
ods.setUrl("jdbc:oracle:thin:@" + connectionString);
ods.setConnectionProperties(props);
Connection conn = ods.getConnection(); <---This is where code errors out with SQLException described above.
return conn;
And that's pretty much it. Anyone have any ideas?

Ok, that looked horrible. Let's try this again:

The network adapter could not establish the connection with Oracle

I installed Oracle in my laptop (windows 2008), and install Hyperion 11.1.2, when I configure Hyperion, it pops up with "the network adapter could not establish the connection with Oracle"?

Hi,
This usually means that the connection details you have put in for Oracle are incorrect or Oracle can not be contacted.
Double check your configuration connection details and make sure you can access Oracle using them details.
Cheers

IO Error: The Network Adapter could not establish the connection in oracle

Hi experts,
I have oracle developer days installed in my vitrual box machine. The connection to oracle datatase (11.2.0.2) contained in the oracle developer days was working fine via sql developer. I use eclipse to write some java programs to connect the database. However, somehow, I cannot connect the database via sql deveoper anymore. This is the error I got when I tried to connect it via basic connection type:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Can anybody shed a light on this issue please. Thanks a lot in advance.

I, too, am running Oracle Developer Days inside VirtualBox.
On which system is SQL Developer installed?
The post errors indicate an OS/networking issue.
when was last time all worked without error?
what changed since then?

Trying to simply connect to Oracle with VBscript/ASP - and I cannot.

This is rather embarrassing. I am pretty fluent with ASP and VBscript, and I have written many a web application connecting to Microsoft SQL Server. Now I have a need to connect to an Oracle database, and I'm beating my head against the wall.
1) Web server is Windows Server 2003 SP1
2) Using ASP (not ASP.NET) & VBscript
3) I have installed the Oracle drivers on the server - it is version 10g
4) The administrator of the Oracle database to which I want to connect has created a username and password for me to use from within my code
5) Here is the code I am trying to run:
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "Provider=MSDAORA;Data Source=XXXXXXX;User Id=YYYYYYY;Password=ZZZZZZZ;"
That's it. 2 lines of code just trying to establish a connection. Using the user name and password provided to me by the administrator, and for Data Source I am using the IP address of the Oracle server (like I have done in the past when connecting to SQL Server). I receive the following error message when viewing this in a browser:
Microsoft OLE DB Provider for Oracle error '80004005'
ORA-12154: TNS:could not resolve the connect identifier specified
Evidently, the Data Source I am using is not correct, but I was provided no other information from the admin. This is the first time any of us have tried to connect to Oracle using ASP/VBScript, so the administrator isn't sure what I need to do ... any help would be so appreciated.

Hello,
I got mine to work by setting up an ODBC System DSN and connecting to it. I think this bypasses the Microsoft driver, which might be what's causing the problem.
Set Db = Server.CreateObject("ADODB.Connection")
Db.Open "DSN=TEST;User ID=userid;Password=password;"
Good luck, I've found it requires a lot of persistence...

JDBC connection to Oracle 10g RAC periodically times out

I've been banging my head against the wall for months now and can't figure out why this is and what's causing it.
We have 6x CF8 servers in our environment. 3 of which work perfectly and the other 3 have the following problem. All 6 machines were installed at the same time and followed the exact same installation plan.
When I configure Oracle RAC data source, some of the machines time-out connecting to Oracle from time-to-time.
Config:
Solaris 9 on both CF and Oracle
CF8 Enterprise with the latest updater.
Apache 2 (not that it's relevant)
6 machines, load-balanced (not clustered), identical install and configuration.
data source config:
JDBC URL: jdbc:macromedia:oracle://10.0.0.3:1521;serviceName=dbname.ourdomain.com;AlternateServers= (10.0.0.4:1521);LoadBalancing=true
DRIVER CLASS: macromedia.jdbc.MacromediaDriver
The problem:
Every few minutes, CF starts hanging requests that deal with a specific RAC only data source. After about 30 seconds, all requests bail and generate this error in cfserver.log:
A non-SQL error occurred while requesting a connection from dbsource.
Timed out trying to establish connection
This happens with any RAC data source on the "bad" servers while the "good" servers don't have this problem. The "bad" server doesn't have any problems with direct (non-rac) Oracle data source.
Already tried:
Moving server connections around on a switch (rulling out bad switch port)
Copying driver from the healthy server (but it's the same installer anyway)
Changed from RAC to normal Oracle type data source - works perfectly. So at the moment I have 3 servers connecting to a specific oracle instance and the other 3 connecting to RAC.
Tried googling and searching forums and even Oracle metalink - nothing I could see relevant to this.
It's a shame that after spending a ton of money on CF8 upgrades and Oracle RAC, we can't really utilize fail-over on the database connection.
Any takers?
Thanks,
Henry

I have the following in my CLASSPATH:
C:\Ora10g1\product\10.2.0\db_1\jdbc\lib\jdbc.jar;
C:\Ora10g1\product\10.2.0\db_1\jdbc\lib\ojdbc14.jar;
C:\Ora10g1\product\10.2.0\db_1\jlib\jndi.jar;
C:\Ora10g1\product\10.2.0\db_1\jlib\orai18n.jar;
Still 'Cannot find type 'oracle.jdbc.pool.OracleDataSource'
Thanks
