Oracle 8i + JDBC 3.0?

Is there any JDBC 3.0 driver that works with Oracle 8i? More precisely, I'm looking to connect to 8i and be able to use named parameters in my CallableStatement's instead of indexed parameters.
Thanks,
Jeff

Jeff,
Unfortunately, I don't think any version of the JDBC driver (with any version of the Oracle database) supports named parameters in "CallableStatement"s. Have you looked at the JDBC samples on OTN?
Good Luck,
Avi.

Error while creating a report that uses Oracle OCI JDBC connectivity

Please let me know why my CR and LF characters are removed from my forum posting *****
Hi,
I was trying to create a report that uses Oracle OCI JDBC connectivity. I am using Eclipse3.4 download from "cr4e-all-in-one-win_2.0.2.zip". I have successfully created a JDBC OCI connection.
The connection parameters are given below:
URL: jdbc:oracle:oci8:@xe
Database: xe
username: <userName>
password: <password>
I have tested the above connection in Data source Explorer and it works fine!!!
But I am getting the following error when I drag-and-drop a table from the list of tables. Not sure what I am missing here? Any help is highly appreciated.

Hi Ted,
Thanks for the feedback. I was able to create a report in Creystal Reports Designer 2008 using OCI. It is not allowing only in the Eclipse plugin. In our environment we are not allowed to user Oracle thin connections and ONLY OCI is allowed.
1) Can you please let me know if there is a way to do this?
2) Will it allow data sources using native database driver?
3) If so, can I use JRC to create these reports from a desktop java program?
Thanks & Regards
Karthik

Oracle 8i jdbc/Tomcat connection issues

Tomcat 4.1.8
Oracle 8i JDBC Driver
I have been able to create the DataSource as a global resource and as a local resource inside the context of the application.
The code hangs when it attempts to create a connection. I have been able to connect to the database and perform the necessary query in a standalone application to ensure that I actually can connect.
JSP Code:
<html>
<head>
<title>VTW App</title>
</head>
<body>
<%
vtw.VTWApp tst = new vtw.VTWApp();
tst.init();
%>
<h2>Results</h2>
<%= tst.getList() %>
</body>
</html>
Java Code (Class called by JSP):
package vtw;
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
public class VTWApp {
String list = "EMPTY";
public void init() {
try{
Context ctx = new InitialContext();
if(ctx == null )
throw new Exception("Boom - No Context");
System.out.println("Context Created ...");
DataSource ds =
(DataSource)ctx.lookup(
"java:comp/env/jdbc/oracleDB");
if (ds != null) {
          System.out.println("DataSource Created ...");
Connection conn = ds.getConnection();
System.out.println("Connection Pulled");
if(conn != null) {
               System.out.println("Connection Good");
               Statement st = conn.createStatement();
               String query = "";
               query += "select grpid, to_char(min(dtlastendtime),'mm-dd-yyyy hh24:mi:ss') ";
               query += "from calc_table where equipmentsernum in (";
               query += "'888000','888001'";
               query += ") group by grpid";
               ResultSet rs = st.executeQuery(query);
               if(rs != null) {
                    list = "";
                    while(rs.next()) {
                         list += (rs.getString(1) + "," + rs.getString(2));
               rs.close();
               conn.close();
               System.out.println("Connection Closed");
          } else {
               System.out.println("Connection Not Established");
}catch(Exception e) {
e.printStackTrace();
public String getList() { return list; }
}

I figured out the issue ...
In the server.xml file the resource & resource params needed to be modified..
1. Set type to oracle.jdbc.pool.OracleDataSource
2. Set factory to oracle.jdbc.pool.OracleDataSourceFactory
3. In the Java code cast the context lookup to an OracleDataSource instead of a java.sql.DataSource
Oracles DataSource does not subclass the jdbc DataSource for its OracleDataSource class everything works fine now.
<Resource name="jdbc/mydb" scope="Shareable" type="oracle.jdbc.pool.OracleDataSource"/>
<ResourceParams name="jdbc/mydb">

Oracle keeping JDBC connections ...

All
has anyone come got any ideas on this:
WLS6.0 sp2 on Win2k
Oracle v8
JDBC connection pool configured with 10 min connections / 50 max conns (in
increments of 5). Shrinking is active, and is set to run every 15mins.
What were seeing is that Oracle doesnt let go of any of the JDBC
connections. It literally keeps them for days on end, until we have to
manually kill them because theyre causing other DB problems.
any ideas ?
tks
will

Hello, I am using ALUI G6 (former Plumtree) and I am experiencing the same problem.
JDBC connections are not released and we reach the connection max number easily.
Please, can somebody help us ?
Thanks for your help,

plse help me how to connect jbuilder to oracle to access the data. I followed jbuilder doc like from the menu (Tools �� enterprise setup �� database driver ��)
but could not select the driver since it is marked as red (uninstalled). How can I made jdbc driver to available to jbuilder.?. I am using oracle 8i. Will oracle 8i supports jdk 1.3 b��cos I have noticed the jbuilder supports from jdk 1.3 onwards. So plse correct me if I am wrong
waiting for reply
sumesh

thanks for u'r reply.
you mean to say i need to install the new JDBC driver (Classes12.zip and nls_charset12) to the oracle/ora8i/jdbc/lib folder.currently this folder contains only classes102 and classes11.zip files and the corresponding charset only.After instaling the new classes12.zip file do i need to set the classpath?.

Connecting to Oracle using JDBC

Hi all,
I am a new to Oracle. I am trying to connect to Oracle using JDBC
The URL with which I tried to connect was:
jdbc:oracle:oci8:@myServiceName,user='myLogin',password='myPassword'
I get an error (ORA-12154)
- TNS could not resolve service name
When I use the same userid, password and service and connect thru' SQL*Plus it goes thru'. Is there any parameter which I am missing. Can anyone throw some light on this. I am held up with this issue badly.
Thanks for all your help and time.

Getting started with oracle and jdbc

i have downloaded ojdbc14.zip from oracle.com
it's documentation only tells you about the api and the packages and nothing about how to configure it.
how do i get started? where do i unzip those files and what to do next?
please help

"The Old oracle.jdbc.driver Package Will Go Away Soon
If you still have existing applications that use the
old oracle.jdbc.driver
package, now is the time to convert your code."
And who is so foolish as to use concrete types
instead of java.sql and javax.sql interfaces or embed
driver class names in their code? Well, anybody who's more interested in optimal performance than being generic, and willing to put up with the headaches of that, such as providers of high-performance OR mapping tools or someone tuning a very heavily used bit. Or anybody working in a committed Oracle-only shop. It's not a one-size-fits-all world...
Again, Oracle is evolving the standard. No, the standard is Sun's java.sql interface.Yea, Sun evolved Java, and Oracle is recommending the use of Datasources to keep step with that evolution...
This still
works, but Oracle is shifting away from <sid> and
using <service name> instead. The alternate syntax
for the URL is:
String url=jdbc:oracle:thin:@<host>:<port>/<database>
This has been true for as long as Oracle has had a
thin, type IV JDBC driver. The URL syntax hasn't
changed.
Yes it has and Oracle says it has, here:
http://download-west.oracle.com/docs/cd/B14117_01/java.101/b10979/urls.htm#BEIJFHHB
Wherein it is written, in Section 3.2.1 of the Oracle� Database JDBC Developer's Guide and Reference, the sesction on the several supported URL formats for Oracle 10.1
Notes:
* Oracle Service IDs are no longer supported at 10g Release 1 (10.1).
They go on to list three URL styles supported:
Oracle Net connection descriptor - like an entry in tnsnames.ora (ick!)
Thin-style service name - the most common, what was quoted above.
LDAP syntax - for having an LDAP service resolve the database for you
However, in the old 8.1.7 JDBC documentation, here:
http://download-east.oracle.com/docs/cd/A87860_01/doc/java.817/a83724/basic1.htm#1006213
Oracle lists support for:
Net8 connection descriptor - Net8 is the old name for Oracle Net
Thin-style sid name - what was quoted in the post to which I first responded.
Thin-style sid name syntax has a colon between the port and the sid; thin-style service name syntax has a forward slash between the port and the service name. SIDs and service names are not the same thing, although they serve the same purpose in a URL (connecting you to the right instance) and often have the same value. However, a SID for a database is set at DB creation time, is unique to the DB, and cannot be changed easily. Multiple service names can be configured for a database, and they can easily be changed (if you're the DBA). Oracle is providing an additional leval of abstraction by moving to service names, to support additional features and choices. While many installations don't need all that and have in essence ignored the distinction bewteen SID and service name, some multi-database projects can benefit from it.
>
StuDerby, I think you should look into this a bit
more. Your advice is far from optimal, IMO.
Yeah, I could've taken the time to write a more generic, newbie friendly repsonse; instead, I lifted directly from the Oracle documentation that was cited earlier since newbies seem to have an aversion to reading documentation.

How to use the Oracle 10g JDBC OCI driver in JBoss ?

Greetings,
I deployed ojdbc14.jar in JBoss and I created an Oracle datasource. I have the following questions:
1. In the datasource descriptor file I have:
<connection-url>jdbc:oracle:oci:@(description=(address=(host=localhost)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME=xe)))</connection-url>
<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
Is it enough in order to use the Oracle 10g JDBC OCI driver ?
2. After having looked-up the datasource and created a connection, the classe of these objects are org.jboss.resource.adapter.jdbc.WrapperDataSource and, respectivelly, org.jboss.resource.adapter.jdbc.WrappedConnection. How can I have access to oracle.jdbc.oci and oracle.jdbc.pool packages ?
Many thanks in advance,
Nicolas

Hello
We were banging our heads on a similar thing, maybe this will help
We needed to convert the wrapped connection to an OracleConnection so that we could do a proxy switch, but maybe you could apply it to your situation anyway
1-you have to convert the Connection object to an OracleConnection in order to use the method that does the proxy switch
The method to do this is getInnermostDelegate()
Once you call this method, you get a new Connection object that can be cast to an OracleConnection object
See below for the snippet of code
// now switch the user and reselect
if (conn instanceof DelegatingConnection) {
properties.put("PROXY_USER_NAME","peter/peter");
oraConn =((DelegatingConnection)conn).getInnermostDelegate();
if (oraConn == null)
out.println("oraConn is null\n");
((OracleConnection)oraConn).openProxySession(OracleConnection.PROXYTYPE_USER_NAME,properties);
2-you have to put a setting in the xml file in conf/Catalina/localhost that allows you to call the getInnermostDelegate() method
By default, Tomcat does not allow you to call this method, it will always return null
You have to change the xml to allow it to return an object
It seems that WebSphere and Tomcat both frown on vendor-specific methods that do not comply with the JDBC standards, but do allow it
Here is the setting:
<parameter>

<name>accessToUnderlyingConnectionAllowed</name>
<value>true</value>
</parameter>
Note, this setting was also put in the conf/server.xml file
Thanks

Oracle 7 JDBC driver

Hi,

One more thing �. I can drop that user through code but not using SQL Plus.
This is the code�.In this code I have logged in using system-manager & I m trying to create user test88 with password test88.I am granting 3 roles to this user Connect , Resource & DBA same as Scott �Tiger. Please help.

I read that by default, JDBC uses an operation mode called auto-commit. This means that every update to the database is immediately made permanent.Still for this program I have tried connection.commit() also , Still it is not working.
I think that problem is not with commit otherwise I shouldn't be able to see that newly created user entry in these tables from Sql Plus:-
1)DBA_ROLE_PRIVS
2) DBA_USERS
3) DBA_sys_privs
Ya but these is no entry in DBA_OBJECTS table for this user.

Spy for oracle thin jdbc driver

Does anyone know a good spy utility to intercept the
query going to the database thru oracle thin jdbc driver?

If you can post the code, I would be happy to look at. I'm not aware of any 'trapping' mechanism for JDBC, although there may be one. Are you confident that you are 'waiting' on the execute of the SQL? It's very unusual for nothing to happen. In most cases, I would expect a long running query, or that you are getting, but not catching an Exception. Code would help if that's possible...

Oracle 8i JDBC to connect to 9i DB?

We are having a big Java application that uses Oracle8i as underlying DB. It uses Oracle 8i JDBC for that. Now, we have to extend this application with a module that writes certain things into another DB. However, this DB is on Oracle 9i.
Q: Can we access a 9i DB using the 8i JDBC driver? If yes, is there a special configuration for the JDBC or the 9i DB?
Note: switching the 9i to "8i compatibility mode" is not an option, since we use loads of 9i features in that DB from another application that uses the 9i JDBC driver!
We tried it and we got loads of exceptions from the 8i JDBC driver.
Any comment or hint is more than welcome - we are running out of time...

Hi
I am trying exactly the same thing and am not able to use Oracle8i JDBC for Oracle9i DB. Have u been able to do this? In case yes, please tell me how.
Thanks

Performance hint: oracle's JDBC is full of trace(), OracleLog.print()

When someone writes OracleLog.print("some stuff"+variable+"other stuff") or print(...), And even if the log mode is false, the VM would compute "the some tuff"+variable+"other stuff" before calling print() or trace().
So like this :
public synchronized Connection getConnection(String s, String s1)
throws SQLException
makeURL();
trace("User us " + s + "URL is " + m_url);
Connection connection = DriverManager.getConnection(m_url, s, s1);
return connection;
So I noticed that the oracle's JDBC code has many of these (I decompiled it:) even though most of the traces are between "if(OracleLog.TRACE)" which is fine.
So you imagine that for a heavy OLTP application, oppening and closing connections very often (even with the cached data source, there are a lot of trace() without the "if(log)") leads to calling trace() often, without useless computing...
