OCI Connections - MDME

Hi,
I am planning to use OCI to connect to other systems like R/3 / CRM / SRM . I don't have XI in place. Can anybody help me how to proceed on this.
Thanks in Advance,
Rajani Kumar K

MDME does not support OCI standard out-of-the-box. The natural way is using MDME API.
MDME API can be used to export any repository element to an XML file according to OCI schema definition. Integration with an OCI solution can be developed on a project basis.

Oracle 8.1.5 and JDBC OCI connection problem

We are running Oracle 8.1.5 on Solaris 7 machine, and our java application running on JDK 1.2 connects to Oracle via JDBC thin driver because we couldn't make jdbc oci driver work.
When we try to connect via oci with the driver originally shipped with 8.1.5, we get:

I searched this forum for answer and only relevent answer from oracle was: consult README file! Readme file mentions that lobocijdbc.so file is shared library file for oci connection. That't all. So what?
I added the directory where libocijdbc8.so resides to LD_LIBRARY_PATH, and System.getProperty("java.library.path") shows content of LD_LIBRARY_PATH correctly.
null

Please this is not simple as simple as checking the classpath and LD_LIBRARY_PATH.
I tried the sample program and the result is the same. As pointed out first by Won, putting the libocijdbc8.so from SDK8.1.6 in the LD_LIBRARY_PATH has no effect at all. It gives the unsatisfied linker error. The sample program fails. However the sample program works fine with the libocijdbc8.so from sdk8.1.5. The library gets loaded. But at the time of creating the connection it gives make_c_state error.
Here is my CLASSPATH, PATH and LD_LIBARY_PATH variables
ORACLE_HOME=/opt/oracle/product/8.1.5
LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/opt/oracle/product/8.1.5/lib
PATH=/usr/openwin/bin:/usr/sbin:/usr/local/bin:/usr/ccs/bin:/usr/ucb:/opt/oracle/product/8.1.5/lib
Hope you are able to provide better answer then check your environment variables.
THE libocijdbc8.so FROM SDK8.1.6 DOES NOT GET LOADED AT ALL.
Waiting for the reply.
Please Help.

Vipul Modi.

Using a Context in Pro*C from OCI connection

Hi all.
I have to write embedded SQL instruction using a context based upon an OCI connection.
I get the connection from an Arbor/BP API that return an LDA_DEF structure and I want to execute the SQL instruction on that connection.
Does anybody of you meet something like this?
Thanx
Claudio

hey VARCHAR is the same as VARCHAR2, isn't it???Yes, they are the same (as long as the ANSI committee is not going to change the definition of VARCHAR)
What I was trying to say is that VARCHAR is an external datatype just like STRING
in any case will it work from STRING of host language to VARCHAR2 of oracle database while inserting???I pointed you to the documentation, but you will only know for sure, if you try it yourself with a small example

Group by SQL functionality under OCI connection

Hi,
I am using OCI connection to load data into Essbase cube. I was just wondering, where to define group by statements in the connection panel. Because i only see Select,From and Where boxes.
Can i put my groupby script under where condition?

You can ignore the other boxes besides the select one, you can put the full sql statement in the select box though remove the select.
Cheers

Load-balancing with OCI connections

Gurus,
Oracle Identity Federation (OIF) can leverage an Oracle database as its transient data store in which case it uses JDBC-OCI connections to connect. However, there is no provision in OIF of defining multiple databases for load-balancing purposes.
Is this achievable using some load-balancer in front of multiple database instances and using a virtual hostname/IP in tnsnames.ora which OIF refers to?
-Vinod

I would say that using two seperate databases (with replication)
as the backend would mean that one database, at any time,
might be lagging the other, depending on which tables are updated
and how replication is implemented.
Connect Time Failover, rather than Load Balancing, might be an
implementation -- to handle Instance Failure (eg node / site has gone down).
Instead of Load Balancing.
Load Balancng between two seperate databases would be usable
if you are sure that either of
a. The underlying data doesn't change
OR
b. The application and users are aware that they might see different data
if there ARE changes to the data, not yet synchronised between the two DBs.

Oci connection-entry point kpufhndl0 could not be located

hi
i use jdev 10.1.3.3 & 10g.
a thin connection to db works fine, but i have to use an oci connection which i fail to set.
i've edited jdev.conf file as described here: http://www.oracle.com/webapps/online-help/jdeveloper/10.1.2/state/content/navId.4/navSetId._/vtTopicFile.db%7Ccdb_rconnectionreqsoci~html/
and added AddNativeCodePath pointing to oracle installation directory.
but an attempt to test a connection returns an error saying "The procedure entry point kpufhndl0 could not be located in the dynamic link library OCI.dll".
i've found a post saying that this issue has been solved by placing jdbc:oracle:oci:@host:port:sid in jdbc custom url field of db settings. not i my case, i'm getting the same error.
any thoughts?
thanks a lot!

OCI Connection Pool

Hi,
How do I use an OCI Connection Pool as a data source in OC4J?
A sample data-sources.xml would be helpful.
A snippet of servlet code would be great!
Thanks

Hi,
OracleOCIConnectionPool extends OracleDataSource and I have
created and attached a example test case OCIConnPoolJNDI.java of
how to register this OCI pool object via JNDI InitialContext and
look it up.
The test assumes a default directory /tmp/JNDI/jndi_dir to exist
that can be changed. You also need dbjava/lib/jndi.zip (or
jndi.jar) and jis/lib/aurora_client.jar in your CLASSPATH

Java 10g OCI connection

I am not able to connect to oracle 10g from java(j2sdk1.4.2_04) using OCI. I have the basic instantclient10_1 downloaded and I have made my classpath and path point to the instantclient directory. Os used is win2k.
I think I am able to load the driver because
Class.forName ("oracle.jdbc.driver.OracleDriver"); given inside try doesn't get caught.
when I use
DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@"); I get runtime error(no compile error)
Exception in thread "main" java.lang.UnsatisfiedLinkError: t2cGetCharSet
at oracle.jdbc.driver.T2CConnection.t2cGetCharSet(Native Method)
at oracle.jdbc.driver.T2CConnection.getCharSetIds(T2CConnection.java:290
7) and some more lines.
The same error I get if I use oci instead of oci8 and if I add orcl after @.
I then tried
java -classpath %cp% -Djava.library.path=C:\instantclient MyJavaApp
which gives
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
But I am able to connect using thin client. Please help in setting my oci connection right.

I just realized after the last post, that not everyone is amiliar with the latin character set.
I'm refering to ISO 8859-1 Or WE8ISO8859P1
The default on my pc is
[AMERICAN_AMERICA.WE8MSWIN1252] which may or may not be what I need.
But some how for me the following always does the trick nicely.
AMERICAN_AMERICA.WE8ISO8859P1
The reall killer in going from UTF to another format or vice versa. The 10g OCI client puts to much faith in Microsoft and defaults you to whatever is in windows.
-- Checking your NLS:
From windows, to check the NLS_LANG, you need to open a command prompt and to run sqlplus in command line mode.
First, check if it's set in the environment:
SQL> host echo %NLS_LANG%
If this reports just %NLS_LANG% back, the variable is not set in the
environment. If it's set it reports something like
ENGLISH_UNITED KINGDOM.WE8PC850
If NLS_LANG is not set in the enviroment, you should check the value
in the registry:
SQL> @.[%NLS_LANG%].
If you get something like:
unable to open file ".[ENGLISH_UNITED KINGDOM.WE8ISO8859P1]."
the "file name" between the '[]' is the value of the registry parameter.
(This is NOT an error but just a "trick" to get the NLS_LANG value)
If you get this as result:
unable to open file ".[%NLS_LANG%]."
then the parameter NLS_LANG is also not set in the registry.
Note: the @.[%NLS_LANG%]. "trick" reports the NLS_LANG known by the sqlplus
executable, it will not read the registry itself.
But then you are not sure if the variable is set in the enviroment or in the
registry. That's the reason of checking with the host commando first.

Issues with OCI connection..

I've been working on this for over a day, with infinite variations on the theme; but I cannot get a basic query to give back data. I've got the following code:
<?
$orcl = <<<OUT
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = orcl)(INSTANCE_NAME = orcl)
OUT;
$oci = oci_connect('','',$orcl)
or die('Connection error.');
if(!$oci) {
 echo 'Connection error: ';
 if(oci_error($oci)) {
 $oerr = oci_error();
 echo $oerr['code'];
 die;
echo 'Initiated connection.';
$input = <<<OUT
 select * from user_objects
 where object_name not like '%SYS_%'
 order by object_name;
OUT;
$query = oci_parse($oci, $input);
if(!$query) {
 $oerr = oci_error($oci);
 echo $oerr['code'];
if(oci_execute($query)) {
 while($output = oci_fetch_array($query)) {
 $object = $output['OBJECT_NAME'];
 echo $object . '
} else {
 echo 'Issue occurred..';
oci_close($oci);
?>
If I open this in a browser, it gives back the following:
 Initiated connection.
 Issue occurred..
In other words, this indicates to me that the connection is being created, but that the query itself isn't being parsed or executed correctly. I've changed various things, for instance inserting 'orcl' instead or $orcl in the oci_connect(), including environment variables, etc. etc.; but I've gotten no further than this with it.
Interestingly, if I do 'php index.php' on the command line, I get an ORA-12557 error (why is the page giving back 'Initiated connection' if this is the case).
Installed Oracle is 10g 10.1.0 on Windows, connection is local. Thanks very much for any input..

Odd; but thank you.
I generally do that in order to offset db interactions a bit from other code and it's never been an issue with postgres interactions; but in this case I changed that and it's working now. I'm off to look into why this is (I imagine oci_parse isn't into it while PEAR::DB or pg_query ignore it; but I'm not certain).
In either case, thank you.

Oracle OCI connectivity issue

Hi All,
We have jave code, that resides in the same server as the Oracle DB( HP-Ux). It uses OCI driver to connect to the server.
jdbc.url=jdbc:oracle:oci8:@
jdbc.username=
jdbc.password=
These are the properties that had been set. The code was working fine in Oracle 9.i. On migrating the server to 10g we get an error saying that
java.java.sql.SQLException: SimpleDataSource:connect - java.sql.SQLException: ORA-01017: invalid username/password; logon denied.
OfCourse the basic idea would be that userid/pwd is not being passed. But we have not been setting the user id and pwd in 9i and it is working there, but not in 10g. So does OCI driver use the os userid/pwd or something for connecting.
Thanks in Advance,
Vignesh

No, we have no such file. In fact i just wrote a simple connection class. The code is as below.
import java.sql.Connection;
import java.sql.*;
class SimpleCon {
     public static void main(String args[]){
          getConnection();
     public static void getConnection() {
     try {
          Connection con = connect();
          System.out.println("Connected");
     } catch(SQLException ex) {
          ex.printStackTrace();
     public static Connection connect() throws SQLException
     final String methodSig = "SimpleDataSource:connect";
     String jdbcUrl = "jdbc:oracle:oci:@"     ;
     String jdbcUsername = ""     ;
     String jdbcPassword = "";
     Connection conn = null;
     try
     Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
     conn = DriverManager.getConnection
     (jdbcUrl, jdbcUsername, jdbcPassword);
               DatabaseMetaData dbm = conn.getMetaData();
               System.out.println(dbm.getUserName());
               System.out.println(dbm.getDriverName());
               System.out.println(dbm.getDriverVersion());
     //setConnectionProperties(conn);
     return conn;
     catch (SQLException e) {
     e.printStackTrace();
          System.err.println("SQL error: " + e.getErrorCode());
          System.err.println("SQL state: " + e.getSQLState());
          throw(e);
     }catch(Exception ie){
               ie.printStackTrace();
          return null;
This particular code works in HP-UX - Oracle 9.i . If we do not pass userid/pwd it usually connects in as OS user, and Oracle has a User id Setup corresponding to the os user.
But the same code does not work in Oracle 10g, even though we have the Oracle User corresponding to the OS user set up. If we pass that particular user id and pwd, it works fine.
Does it throw and light.
Thanks

OCI connect error reported to cause core dump

I use OCI in my developped library. Other developers use my library for their development purposes. Last night, the oracle server went down for patching, and a user reported a core dump that I recognized it is comming from my OCI section of library.
I do OCI initialization, select, execute a query, and cleanup.
Has there been any reports as for the case, when a connection is initialized, and the server goes down after successful initialization but before calls to execute a query or commit?
Any comment???
I have the error message below, and replace prepriotory info with xxxxxxx.
thanks,
--M

We have seen core dumps in system calls earlier and have tried to debug them. We did not have the exact same stack as you but the core used to show up a stack in _malloc.
As it turned out that we had out of bound array reads (used purify to detect this) and which resulted in this dump. So the stack shown in this case could be totally misleading and the real cause could be somewhere else.
Hope this helps.

Is it possible to use an OCI connection JDBC?

If a Java application relies on a native C library to access an Oracle database, and the native library uses the OCI, is it possible for the Java code to share an established connection

<BLOCKQUOTE>quote:<HR>Originally posted by Jacques Vidal:

(sorry, incomplete post, last part follows:)
in JDBC using a mechanism like sqllda() or SQLEnvGet()/SQLSvcCtxGet() ?
I need this to keep transaction consistency, and can't translate the C code to Java, as it's still used by other non-Java applications.
Thanks.

OCI connection to oracle FAILED !!!

Hi all,
I would like to use OCI and to user Oracle OS authenication to connect to my Oracle database.
I have already set up proper user account in Oracle in order to make OS authenication works.
However, when I run the java program, it gives me the error as below :
Exception in thread "main" java.lang.NoClassDefFoundError: makeConnection
My connection is as below :
Connection conn = DriverManager.getConnection("jdbc:oracle:oci8:
/@ems","oraemsu1","oraemsu1");
any hints ?

Hi,
Really thanks for your suggestion. I will try this out.
The reason why i need to immplement oci is that the program is in fact not develop by me, but by some developers. They are lazy to encrypt username and password and on the other hand they also dun want to hardcode the username and pwd in their jave programm!!!
As I am the dba, I need to set the Oracle database to support OS authenication for their program to connect to the oracle database. And I know OCI driver is the only driver support OS authenication .
BTW, do you have any other good alternatives for me then ?
Also, if I am using AIX, should the lib path be $LIBPATH instead of LD_LIBRARY_PATH ?
Many thanks !

Oracle OCI Connection Problem

Could you please help me?
When I try to access Oracle using TopLink and OCI this error occurred
# An unexpected error has been detected by Java Runtime Environment:

[error occurred during error reporting, step 270, id 0xc0000006]
I have used these libraries
- ojdbc14.jar
- toplink-essentials.jar
- toplink-essentials-agent.jar
Also I used netbeans v6
and Apache Tomcat 6.0.14

Please if have a solution to this problem let me know,
Please don't say use thin driver because OCI is required on my envirnoment

Are you sure you are using the Oracle OCI JDBC driver? From you stack trace you are not, you are using the JDBC-ODBC bridge.

j oracle.toplink.essentials.internal.databaseaccess.DatabaseAccessor.closeDatasourceConnection()V+4
Ensure you set your database url and driver class in your persistence XML (or DataSource config) to be the Oracle JDBC driver and the Oracle OCI url.
i.e.
toplink.jdbc.driver - oracle.jdbc.OracleDriver
toplink.jdbc.url - jdbc:oracle:oci:@instance
