Oracle lite with JDBC crashes

I am connecting to an Oracle lite database on NT Server 4.0 with
JDBC and trying to run an simple insert statement. If I try to
run the same statement again (which should throw an exception
since the pk already exists) I get an application error - not an
exception as expected - I get the same thing when executing a
"delete from.." stmt on an empty table. These same stmts work
fine in Oracle8i.
Also, if I use access with ODBC to view the tables access will
often freeze up on me.
Any Help would be appreciated.

You probably mean if you can call a Java Stored Procedure from ADOCE application. PL/SQL packages are not supported in Oracle Lite database. The answer is no. For more information see Developers' Guide for WindowsCE, Chapter 4

Trouble to connect to Oracle Lite with JDBC

Hi.
I have installed Oracle Lite 9i on my PC (Win 2000 Pro). Then I connected an HP Jornada 525 (WinCE 3.0) and with
ActiveSync I installed the Oracle Mobile Client. Using MSql, I created some tables and did some data inserts - Oracle
is working fine on the Pocket PC. The next step was to create an Java application that will run on the Jornada to
connect to this database and edit its data. Here is the initial source code:
import java.sql.*;
public class JDBCEX {
public void JDBCEX () {
public static void main(String args[]) {
Connection conn = null;
Statement stmt = null;
ResultSet retset = null;
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:Polite","system", "manager");
catch (Exception e) {
System.out.println(e);
System.exit(0);
This works fine on my PC, but in the Pocket PC it gave me: java.sql.SQLException: Internal Error. This after I expanded
the jar files, 'cause before it tells me that ther is no oljdbc40 on the shared library path. I adjusted the classpath on the
registry, but i does not have any impact ... There is no file with name oljdbc40, only JARs olite40 and olitejdbc40. I installed
olitejdbcpj40.jar, and setting this library leads to the same error above.
What could be wrong? Do you have any tutorial or can you list all steps necessary to bring this working?
Thanks

If you're attempting to use the ODBC API directly, have you downloaded the ODBC SDK from Microsoft? That will include some sample code, which is a great starting point. So far as I'm aware, you shouldn't need to configure anything in Borland C++ that you don't have to configure in any other C++ compiler to use ODBC.

Can't connect to external Oracle DB with JDBC connector

Hello guys,
I had failed to connect to connect external Oracle via JDBC connector .
Could you please help me to resolve the problem ?
Backgroud:
We need to connect the external Oracle DB with JDBC connector, because BI need to connect to the target Oracle. If the JDBC connector suceed, BI will create a UD which use the datasource
we create in Visual admin to connect to the external Oracle DB.

Connecting Oracle 8i with JDBC

Hi Friends,
I am facing a problem while doing a connection to my DB which is ORACLE 8i with JDBC communication channels thorugh xi.
I am getting an error "Error during database connection to the database URL 'jdbc:oracle:thin:@hostname:ORCL' using the JDBC driver 'oracle.jdbc.driver.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:oracle:thin:@hostname:ORCL': SAPClassNotFoundException: oracle.jdbc.driver.OracleDriver"
In one of the SAP notes:867176 its mentioned .....
3. Which JDBC driver version is certified to connect to which database version?
              From the Oracle side:
              The Oracle 10g JDBC drivers are certified to work with currently-supported versions of the database.
              JDBC 8i/9i Thin drivers are certified to work with supported (previous) versions of the database.
              Existing and supported JDBC drivers are certified to work with Oracle Database 10g.
              From the SAP side:
              SAP only supports homogeneus setups. The oracle driver major version must match the database major version, and the driver version must not be smaller than the database version.
              SAP does not support Oracle 8i drivers.
Is it not possible to connect to my DB? Is SAP supports the connection to 8i oracle database? any idea,,,
Regards,
Sunil.

Hi,
Following is the connection string that we are currently using for connecting to Oracle 8i.
This setting has been working for us. give it a try.
connection string : jdbc:oracle:oci8:userid/password@server
Note that this connection string is only if you use the Oracle OCI driver. The OCI driver requires a shared library or DLL on the server.
The thin driver for Oracle is more commonly used as it doesn't require any additional libraries. The connection string is as already listed above:
jdbc.oracle.thin:@server:port:SID
There is no need to put the user and password into the connection string in the adapter config, putting it into the user and password fields works just fine.
Regards,
Suryanarayana

Oracle lite with CLOB

Hello all
I have a need to inserts large CLOBS in the Oracle Lite database. However the data goes in fine, but when i retrieve it back, i recieve null. I could see that the data is stored in the database.
I use the sun.jdbc.odbc.JdbcOdbcDriver driver, and i use the Toplink to speak to database with oracle.toplink.internal.databaseaccess.OraclePlatform. The news group on the toplink suggested me that the there might be some limitation on the length of the CLOB that can be retrieved, based on the driver used. So i am posting the question here. Any information regarding the issue will be highly appreciated.
Thanks in Advance

We do not support CLOBS in Lite. Please try using BLOBS, which are supported.

Local oracle access with jdbc thin

hello there
it need help despratly,
im developing an applet to talk to remote oracle dbs using jdbc
thin
but i also want an applet to be able to talk to a local oracle db
on the same hardisk.
for a remote connection the follwing stringis used at my
university
static final String connect_string =
"jdbc:oracle:thin:scott/[email protected]:1521:DSC1";
but what do i subsitute for thr host as i want to access the db
on my hard disk?
i need as much help ASP, as im well behind my schedule for this
project.?
also i take it that to allow this and access to remote servers
other than the web server, the applet needs to be signed, is this
possible with jdk1.1.x compatble browsers?

The thin driver reqiures a TCP listener to be running. If you are
using Personal Oracle for the 'local' RDBMS then it doesn't have
a listener (with the default installation). Start the listener
and you should be able to connect. You will also want a local
webserver of some sort to serve the applet to you as well, but
anything (even TinyWeb) will do for that.

Use of Complex Oracle Object with JDBC

How can I use Oracle Object(or PL/Sql type) with JDBC
I have a structure of record with some attributes and table of another attribute.
My types are defined as follows !
<code>
CREATE TYPE EMPLOYEE_GRADES AS TABLE OF VARCHAR2(50)
CREATE TYPE EMPLOYEES AS OBJECT(EmpName VARCHAR2(50), EmpGrades Employee_Grades)
</code>
My custom object might have the following structure (or should it be different)
<code>
public class EmpColl implements CustomDatum, CustomDatumFactory
-- other stuff ----
/* fields */
public String empName;
public Collection empNos;
</code>
I want to pass an variable of type EMPLOYEES to an procedure.
Thanx in Advance
Chetan
[email protected]

<code>
CREATE TYPE EMPLOYEE_GRADES AS TABLE OF VARCHAR2(50)
CREATE TYPE EMPLOYEES AS OBJECT(EmpName VARCHAR2(50), EmpGrades Employee_Grades)
</code>The easiest is to use JPublisher (which comes with the SQLJ distribution).
Say:
jpub -user=username/password -sql=EMPLOYEES:Employees,EMPLOYEE_GRADES:EmployeeGrades
You will get (among others) the Java files Employees.java and EmployeeGrade.java. Go ahead, compile and use them.
Look in [Oracle Home]/sqlj/demo/jpub for a number of additional examples, and in the JPublisher User's Guide for background info.
The next (9.2) release of JPublisher will also provide some support for accessing legacy PL/SQL types from Java.

How to obtain oracle lite polite jdbc driver

Hi
I have an old project which I need to compile. However this project imports oracle.lite.poljdbc.OracleCallableStatement and
oracle.lite.poljdbc.OracleResultSet.
Where can I obtain a zip/jar/exe that contains these classes? Or if they are obsolete, which classes can I use as replacement?
Thanks in advance!
Alex

Hi
It should be in a JAR file under $ORACLE_HOME/Mobile/classes or $ORACLE_HOME/Mobile/sdk.

Hi:
That error code is Service Name related error.
Oracle error docs has the following
TNS-12505 TNS:listener could not resolve SID given in connect descriptor
Cause: The SID in CONNECT_DATA was not found in the listener's tables.
Action: Check to make sure that the SID specified is correct. The SIDs that are currently registered with the listener can be obtained by typing "LSNRCTL SERVICES listener_name". These SIDs correspond to SID_NAMEs in TNSNAMES.ORA, or DB_NAMES in the INIT.ORA file.

Connecting to an oracle db with jdbc

I downloaded the jdbc drivers and unzipped them to "C:\SDK\Classes", therefore they're "C:\SDK\Classes\oracle\jdbc\..."
My classpath is set to "C:\SDK\Classes\"
public void connect()
        String serverName = "********";
        String portNumber = "1521";
        String sid = "oracle9";
        String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
        String username = "*****";
        String password = "*****";
     Connection connection = null;
     try
            String driverName = "oracle.jdbc.driver.OracleDriver";
            Class.forName(driverName);
     // Create a connection to the database
     connection = DriverManager.getConnection(url, username, password);
     catch (ClassNotFoundException e)
        System.out.println("Could not find the database driver");
         catch (SQLException e)
            System.out.println("Could not connect to the database");
}I get the error "Could not find the database driver" when i run this.
Can anyone suggest anything?
Thanks!

Check your classpath and webserver library directory
it must be classes12.jar file in the lib directory that using the webserver
or classpath
.;c:\jdk1.3.1\extlib\classes12.jar;
and check your jdbc driver version

Connecting Java application to Oracle Database with JDBC

How can I connect my Java application using Oracle 11g database?
Please provide the steps involved along with the coding.

What kind of Java application? Stand alone/desktop? Or web? Do you need dedicated, individual connections, or connection pooling for 10,000 concurrent users?

Bad Performance with Oracle Lite 4.0.1

I have a table in Oracle Lite with 17000 records and 110 fields. A SELECT on this table needs 1 minute to finish. The same table and query only needs 1 second on Oracle 8i Server. MSDE also needs 1 second. All the relevant fields are indexed. Are there any parameters in Oracle Lite that we can tweak? Is there something else I'm forgetting?

Hi Shivek,
An excellent solution for this is provided in the metalink Note:455905.1.
Let me know if you have more questions.
Thanks

Oracle Lite on Windows CE

It is given in documentation that
"Java stored procedures and triggers, and the Oracle Lite JAC and JDBC interfaces are currently not supported on Windows CE" is
there is any other way to accomplish this task. I want to access Oracle Lite database
and perform advance replication thr java program on Windows CE platform.
null

This may be helpful (if you still need it)
In order to use Oracle Lite with Windows CE, I had to write a dll using the libraries and dll's from oracle that were compiled for Windows CE (depending on your processor type: MIPS, SH3, SH4 are supported) There are also sample applications (with source code) that I used to help write the dll. If you install Oracle Lite on a Win32 system, the source code for the sample applications is under /<oracle dir>/lite/pda40/wince and then look under the appropriate processor type.
I am still working on getting Replication to work from the CE device. I am focusing on HTTP replication, but if you have any idea of how to replicate at all from CE....
