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?
yours

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.

SSL connection with JDBC thin driver

I am attempting to connect to an instance of Oracle 10.2 using the JDBC thin driver with SSL. I want to use the encryption feature of SSL only, but I can not perform the getConnection on the DataSource without running into an exception. According the JDBC docs, the SSL encryption feature is new for the 10.2 release of the JDBC thin driver, but I have seen no working examples. See http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/overvw.htm#CHDIHFBD
I am using ojdbc14.jar on Java 5.0 using a standalone application, and it fails with an IOException (The network adapter could not establish the connection) (Error code 17002). I even enabled tracing using the ojdbc-g.jar to try to figure out what the REAL problem is, but it was not helpful at determining a root cause. I changed the driver type from "thin" to "oci" (and installed Oracle Instant client for my test machine) and the connection works just fine using the same tnsnames file, the same wallet, and the same cipher suite. From the Java perspective the only thing that changed was four characters -> "thin" became "oci". I am still using password based authentication as I understand that the authentication part of SSL is not supported in the thin driver on 10.2
Can anyone verify that the SSL encryption works with JDBC thin as advertised? (not the Oracle Net encryption, but rather the one described in Chapter 11 of the JDBC Developer's Guide. See http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/sslthin.htm#CHDFEICG
I really would prefer to avoid using the OCI driver because of its dependencies on the native platform. Is there something special with how the users are created or how the JDBC API should be used? I am setting what I think to be appropriate parameters (oracle.net.wallet_location, oracle.net.cipher_suites) all to no avail. Does anyone have a working example they can provide?

1) I would suggest posting this question over in the JDBC forum. The folks over there are far more likely to be able to help you.
2) When you do post this question over there, I would strongly suggest posting some sample code/ configuration scripts so that folks can reproduce your problem on their local machines. That tends to make it far easier to debug the problem and/or to notice if you've missed a step.

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.

               System.out.println ("The Oracle thin driver loaded!");

Oh, JAVA gods(!) I am stuck. <quite pissed> :(
...and what am I doing wrongly with JDBC thin?!
H E L P !!!!!!!!!!!!!!!!!!!

Thanks Shirish! (Symmetrical WRT sound!)
Here is my adaptation of that snippet which compiles, except for one error:
Class OracleDriver not found. How did you handled your classes12.zip and
your class path? Exactly what should happen at the command line?!
That is really my BIGGEST issue with these vendor drivers outside JDK.
I am aware that many styles work, but given the EXACTLY correct environment
setting. This is my main issue and why I specified my exact directories.
1. If Oracle is in: ~ root/Oracle
2. Thin driver in: ~ root/drivers/classes12.zip
3. My connection code in: ~root/sources/connDB.class
What EXACTLY should happen to compile and run:
import java.sql.*;
public class connDB {
public static void connect() {
          Connection     conn;
          Statement     stmt;
          ResultSet          rtset;
          String          SQL;
          try {
DriverManager.registerDriver(new OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:" + instance, username, password);
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
rtset = stmt.executeQuery(SQL);
catch( SQLException sqle ) {
               System.out.println ("Did not load driver.");
               sqle.printStackTrace ();
public static void main( String args[] ) {
          connect();
I am sitting @~root/sources>
So far I have no problem running any non-driver associated classes from there.
But how do I make my code find this OracleDriver?! And should classes12.zip
be extracted? I was told it should remain intact. Point is where should it be
or what command line "command" gets this connDB.class + OracleDriver to run?

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.

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.

ASO - checksum fail with JDBC thin client on Windows

I'm trying to configure Oracle Advanced Security for SQL Developer. I'm using SQL Developer 1.5.1 (downloaded with the included JDK). When configuring the connection I select Connection Type: Advanced. My JDBC URL is:
jdbc:oracle:thin:@(description=(address=(protocol=tcp)(host=hostname.com)(port=1234))(connect_data=(service_name=DVLP)(SQLNET.ENCRYPTION_CLIENT=REQUESTED)(SQLNET.ENCRYPTION_TYPES_CLIENT=AES256)(SQLNET.CRYPTO_CHECKSUM_CLIENT=REQUESTED)(SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT=MD5)))
This works great in Linux. But on a fully patched Windows XP machine when I try to connect I get "Io exception: Checksum fail Vendor code 17002"
Note that this is only a problem with the thin client. If I use the OCI client (jdbc:oracle:oci:@....) it works fine.
Also note that the db to which I'm trying to connect is a 10g database with these sqlnet.ora parameters:
#ASO Encryption
sqlnet.encryption_server=required
sqlnet.encryption_client=required
sqlnet.encryption_types_server=(AES256,3DES168,3DES112)
sqlnet.encryption_types_client=(AES256,3DES168,3DES112)
#ASO Checksum
sqlnet.crypto_checksum_server=requested
sqlnet.crypto_checksum_client=requested
sqlnet.crypto_checksum_types_server = (MD5)
sqlnet.crypto_checksum_types_client = (MD5)
SQLNET.INBOUND_CONNECT_TIMEOUT_LSNR1251=120
# Require clients to be Oracle 10g or higher
SQLNET.ALLOWED_LOGON_VERSION = 10
Has anyone else seen this?
Thanks for your help!

As a test I created a simple Java program to connect to the db. I used the same ojdbc5.jar that is shipped with sql developer. My test program ran fine. So it would seem the problem is SQL Developer specific.
The class:
import java.sql.*;
public class testJDBC_ASO {
public static void main(String[] args) throws SQLException {
DriverManager.registerDriver (new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@(description=(address=(protocol=tcp)(host=hostname.com)(port=1234))(connect_data=(service_name=DVLP)(SQLNET.ENCRYPTION_CLIENT=REQUESTED)(SQLNET.ENCRYPTION_TYPES_CLIENT=AES256)(SQLNET.CRYPTO_CHECKSUM_CLIENT=REQUESTED)(SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT=MD5)))",
"username", "password");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION");
while (rset.next())
System.out.println (rset.getString(1)); /
stmt.close();
The output:
C:>java -cp ojdbc5.jar;. testJDBC_ASO

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

Ora-00933 with JDBC thin

Hi,
after changing the Oracle DB-driver from the one provided
with CF Enterprise to Oracle JDBC thin I run into ora-00933
"Command not properly ended" exceptions. The SQL code syntax ist
correct (runs in SQL*plus) and worked fine before. It seems to be
related mostly to insert from subquery...
Has anybody an idea what is going wrong?
Are there any patches / fixes available ? (working with CF8
Fix2, Oracle 10gR2, W2k3)
Thanks in advance

quote:
The SQL is something like
Your SQL, as it stands, looks OK to me, except
you have an unnecessary extra set of ( ) around your select
statement.
insert into fu_dokument_status (oid, benutzer, status, datum)
select 123, 'asdf', 'gelesen', sysdate
from dual
where not exists (select *
from fu_dokument_status
where oid=123
and benutzer='asdf'
and status='gelesen' )
Having said that, you obviously provided the SQL
after parameter substitutions have been made, and it would
have been much more useful to see the actual CF code that you are
using, you know, what is actually contained in your CFQUERY. I
suspect that there may be something else going on with the way that
it is written. Generic "something like" isn't terribly helpful.

Dear Maran,
Yes! You can always increase the number of process and session to a higher limit at database end, but it won't be a feasible solution. Rather look into the areas which are the cause of this and try to solve them out.
What if you increase these parameters at database end to accomodate more and more sessions, and allow them to use more and more resources like process, and still they keep on increasing rather than getting closed. It would be worthless use of Database server Reources.
It is really very simple, just look for the SQL statements which are having last_call time a long back (from V$SESSION and V$SQLAREA or you may use tools like TOAD), and try to find out the reason why they are not releasing the connections back to Connection Pool. Check out these SQL statements in the application code and ensure Connection Handling is done over them.
Some "RS.CLOSE" type of command is there in java (I am not sure with the proper syntax)

Manoj.

Problems with jdbc thin driver (Euro Symbol)

Hello,
at the moment it is impossible for me to write or read euro characters to a database using a jdbc thin driver.
I am using
ojdbc14.jar (version 10.2.0.3.0) and orai18n.jar (also) together with JDK 1.4.2.
Charset of the database is WE8MSWIN1252. It does not work on ORACLE 9.2.0.1, 9.2.0.6 and 10.2.0.2.0 (others I have not tried). But the problem seams to be in thin client.
Inserting Eurosymbols using a PreparedStatement works quite well. Using a normal Statement does not work.
Also the values getting from a ResultSet are incorrect.
After several test I downloaded a patch 4659157 for ojdbc14.jar and 5470375 for orai18n.jar. After installing the patch the euro characters were returned, but:
In several selects of numeric fields (not all, seams to be random) my resultset returned the Euro character instead of 0 and so on.
Driver for 9.2 works quite well, but does not support 10g Release 2 (and contains also some funny bugs)
Following solutions are not suitable for us:
Changing the character set of the database (come on, this cannot be serious. I cannot change the character set of more than 100 databases)
Using the newest driver (ORACLE 11). We are still using JAVA 1.4.2 and cannot migrate our application at the moment.
Using an oci client. Not possible, no ORACLE client on clients...
Has anyone an idea how to deal with this?
Does anyone know when ORACLE is going to release a new jdbc driver for JAVA 1.4.2 (maybe 10.2.0.4.) ??
Regards,
Christian

Just installed PATCH 4659157 and 5470375 from metalink. The Euro problem seams to be corrected.
BUT:
Another problem occurred. Sometimes numeric values are returned wrong (0 from a numeric field comes as euro, 1 comes as Á (2 and 3 too).
This error seams to be random to me.
Our application is selecting a rowid from a table and after that fills several textfields in a frame by selecting the content in a way like this:
select [column1] from [table] where rowid=[rowid]
select [column2] from [table] where rowid=[rowid]
if I select the numeric column with select nr. 77 I get a wrong value. If I select it at nr. 10 I get the correct value.
The selects are done by a normal Statement object creating a ResultSet. The Value from the ResultSet is fetched by getObject() method.
I also tried to write a test program executing only the selects of the application, but it gives me correct results.
Also when selecting all the fields in one select I get a correct result.
Using a different charset than WE8MSWIN1252 seams to give correct results. Using the OCI driver returns correct results.
Using ojdbc14.jar and orai18n.jar Release 10.2.0.3. unpatched produces the same error (and does not return Euro symbols)
Using ojdbc14.jar and orai18n.jar Release 10.2.0.2. returns correct results (but wrong Euro)
Has anyone had the same problem yet?
Regards,

12.1.3 EBS with JDBC Thin Client

Hello,
I have question about JDBC Thin Client, typically dbc file and context file define connection to RAC Database using thin client, as far as I know jdbc thin client does not support TAF feature when there is database node down, the connection not direct to surviving node until relogin.
APPS_JDBC_URL=jdbc\:oracle\:thin\:@(DESCRIPTION\=(ADDRESS_LIST\=(LOAD_BALANCE\=YES)(FAILOVER\=YES)(ADDRESS\=(PROTOCOL\=tcp)(HOST\=XXXX-SCAN.xxx.com)(PORT\=1521)))(CONNECT_DATA\=(SERVICE_NAME\=DBSID)))
<jdbc_url oa_var="s_apps_jdbc_connect_descriptor">jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS=(PROTOCOL=tcp)(HOST=XXXX-SCAN.xxx.com)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=DBSID)))
And parameter APPS_JDBC_DRIVER_TYPE=THIN in dbc file, is it must to be THIN? What is the function of FND_JDBC_USABLE_CHECK=false/true?
Also to make connection work to surviving database node, we need to restart process OACORE that connect to down node, is that expected behavior and workaround? Is there a way or is it supported to use THICK client in R12 EBS?
Thank you.

Please see the following docs.
Is Transparent Application Failover (TAF) Supported on the JDBC Thin Driver? (Doc ID 297490.1)
Configuring and Managing E-Business Application Tier for RAC (Doc ID 1311528.1)
Thanks,

How to handle ORA-28001 error with JDBC thin driver ?

Dear reader,
As you all know, ORACLE returns error ORA-28001 upon a connection attempt when the user's password has expired.
Handling the error in OCI is quite simple, thanks to the function OCIPasswordChange(). However, I have not been able to find a JAVA equivalent in the Oracle JDBC library.
I have found a field called oracle.jdbc.driver.OracleDriver.set_new_password_string, and a field oracle.jdbc.OracleConnection.CONNECTION_PROPERTY_SET_NEW_PASSWORD, but I have really no idea on how to use them (if appropriate) so as to allow the user to change his/her password on the fly.
I greatly appreciate having any advice from anyone who happened to be faced with that problem.
Best regards.

Hi,
according to Note [124970.1 Example: How to Change an Expired Password in JDBC?|https://metalink2.oracle.com/metalink/plsql/f?p=130:14:2181952130729466734::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,124970.1,1,1,1,helvetica] it's possible with JDBC Thick (OCI) driver only.

Maximum number of connections for MS Access with JDBC

Hi guys,
does anyone know about the maximum no. of connections that MS Access can have with JDBC...

MS Access has not limit. It doesn't work that way.
There is certainly going to be some resource limit however, if nothing else then memory will eventually run out.
