Oracle oci8 driver

Hi All,
I am able to connect with a oracle database using the thin driver(windows os),
but not able to connect with the oci8 driver, inspite of putting the dll that is required.
It is throwing the exception below,
Exception in thread "main" java.lang.UnsatisfiedLinkError: get_env_handle

Actually, I meant a version conflict between the Oracle JDBC drivers (in classes12.zip) and the installed OCI binaries on the same computer. If both the JDBC and OCI dll's those that were installed from the same Oracle distribution media you should not be getting these errors. Double check your path and classpath. Make sure the versions are precisely the same (8.1.7 for example, not just 8i).

Oracle (OCI8) driver not available!

I have installed DAC successfully. So I start my client and am trying to create a new connection.
I did the following:
1) Clicked Configure
2) by default, Create connection is selected, I clicked Next
3) Entered Name, selected Connection Type as Oracle(OCI8), entered TNS names as ORCL and created new authentication file.
4) Clicked Test Connection and it shows the error 'Can't connect to the database'. When I click Show details, I get the following:

Resolved. ojdbc14.jar was missing in \bifoundation\dac\lib.
Downloaded and copied the file to the location and rebooted my system.

How to set the oracle oci8 driver?

hello all:
I've set up the oracle thin driver and it works. but when I change to
oci8.it don't work
below is config and errors:
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"
InitialCapacity="5" LoginDelaySeconds="5" MaxCapacity="15"
Name="ocipool"
Properties="user=yanji;password=yanji"
Targets="myserver" URL="jdbc:oracle:oci8:@pg01"/>
Could not load 'oracle.jdbc.driver.OracleDriver
If this is a type-4 JDBC driver, it could occur if the JDBC
driver is not in the system CLASSPATH.
If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)
have not been installed properly on your system
or in your PATH environment variable.
This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL
have not been set properly.
3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.
For more information, read the installation documentation
for your JDBC Driver, available from:

Hello, Jenny I am glad you found your resolution. I too am having problems isung
the oracle 0CI8 driver. My connection pool is creating fine, but my server is
crashing with JVM errors.
Here are my configurations.
DBase=Oracle 8.1.7,OS=Win2000, running 6.1 with Portal 4.0
pool config =
<JDBCConnectionPool CapacityIncrement="0"
DriverName="oracle.jdbc.driver.OracleDriver" InitialCapacity="5"
MaxCapacity="5" Name="ccConPool"
Properties="jdbc.url=jdbc:oracle:oci8:@servername:1521:orcl;user=XXXXX;password=XXXXXX;dll=ocijdbc8;server=orcl;protocol=oci8;dll=ocijdbc8;protocol=oci8"
RefreshMinutes="0" Targets="portalServer"
TestTableName="WIP_TABLE" URL="jdbc:oracle:oci8:@servername"/>
My classpath sets my classes12.zip file first. My path sets %WEBLOGIC_HOME%\bin\oci817_8
and %WLCS_ORACLE_HOME%\bin.
Am I setting the right dll and protocol in my .dll? Where can I find documentation
on these properties definitions?

although I put the classes12.zip into the CLASSPATH.but the weblogic.jar
in
front of classes12.zip.so classloader
load the class from weblogic.jar. so I can use thin driver(weblogic
implements this function with class,but not for oci8 )
..this is really a big pitfall !
put the classes12.zip in front of weblogic.jar .all perfect!

Its not CLASS_PATH it should be CLASSPATH.
when you say oracle\bin and oracle\lib , on what driver is the oracle
folder?I meant to say 'on what drive' not 'on what driver'
you have to specify the full path.
post your startup script here.

1. Dont copy this file oci8jdbc.dll, to bin folder. Make sure
you
place
<oracle_home>\lib in your PATH before starting the server. Make
sure
your
ORACLE_HOME environment varable is set to <oracle_home> folder.
eg. set ORACLE_HOME=c:\ora816 before starting the server.
so you must have done something like
set ORACLE_HOME=c:\ora816
set PATH=%ORACLE_HOME%\bin;%ORACLE_HOME%\lib;%PATH%
2. double check if you set your CLASSPATH something like this,
CLASSPATH=%ORACLE_HOME%\jdbc\lib\classes12.zip;%CLASSPATH%
in the server startup script just before starting the server.
3. start the server the connection pool should work.

I've edited the StartWeblogic.cmd, set the classes.zip into CLASSPATH,and
copied the oci8jdbc.dll to the bea\wlserver6.1\bin. errors stillappears!
my weblogic version is 6.1 and oracle is 8.1.6 .
why the thin driver is ok but the oci driver can not work?
I logined in the oracle website and look for the jdbc.but I find
that
jdbc
all provide for jdk1.2 or jdk1.1. because the weblogic6.1 based
jdk1.3.
I
think i can not use those drivers.
I think my oracle driver is ok,because i installed the jboss and
bas4.5
in
my computer. they all can use oci8 driver properly.and they all
based
jdk1.3.
by the way. I 've tryed added the oracle\bin path inStartWeblogic.cmd,
nothing changed !
again below is my config : I want to know whether my config right?
(the property DLL and Protocal auto added by the weblogic)

To use oracle oci8 driver:
You should have classes12.zip in weblogic classpath.
You should have ocijdbc8.dll in your weblogic path..
You can download ocijdbc8.dll from oracle website.

Oracle oci8 driver problem

Hello !
I work with Weblogic 701, oracle 9.2.0.1 database, oracle 9.2.0.2 client, and
oracle jdbc drivers classes12.zip
When I connect with the oci8 (not the thin) driver and try to execute the application,
I get this error :
java.lang.UnsatisfiedLinkError: Native Library D:\oracle\ora92\bin\orageneric9.dll
already loaded in another classloader
I have to shutdown weblogic and start it again. If I redeploy my application,
I get the same error and I have to shutdown again ...
and when I connect with the thin driver and try to execute the extract method
on a XMLType object, I always have a sqlException.
I see on the web that the extract method can only be applied with the oci8 driver.
How can I do ???
Thx

Hi. Go to oracle's site and download the very latest appropriate thin
driver for your DBMS, and put the driver ahead of all weblogic stuff in the
classpath the server is going to use.

Does multilingual work with Oracle oci8 Driver? I am facing problems with oci8 while thin driver works fine ...

Hi, I am currently working on iPlanet 6.0 SP4 with oracle 8.1.6. I am planning to make my application language independent. while testing I figured out that if i use oci8 driver or oracle, it doesn't support other language characters while the thin driver supports fine. Can anybody help me regarding this? Is this a bug, or some possible configuration issue? Has somebody came across this problem before? How do i go about it ?

We faced same issue. Looks like the native driver does not support the automatic data encoding/decoding from/to database. You can always workaround this by reading everything as byte stream and then by letting java handle the encoding/decoding. But we decided to use type4 thin driver which does this automatically if you set the content type. Anyway we are told that later versions of IAS may not support native drivers, so if you are serious about multi language shift to type4 thin drivers now itself.

Memory leakage with oracle oci driver

I have developed a Solaris8 client/server application using the JAVA IDL CORBA implementation. The client sends requests to the server to update the database (database is Oracle 8.1.7 and I connect to it using oci oracle drivers). Requests are sent one at a time. No concurrent connections. I have a static connection that I establish with database once I start the server. If that connection is lost for any reason (timeout or database faliure) the application tries automatically to reconnect to database. I have noticed that if the new connection to database fails and an sql exception is thrown, memory used by the application process increases. This memory is not garbage collected so application hangs. I tried similar behaviour with the oracle thin driver and things went fine. There was no memory leakage.
I would really appreciate, if you can help me in this since I can't use the thin driver because of failover limitations.

I have noticed
that if the new connection to database fails and an
sql exception is thrown, memory used by the
application process increases.
How have you noticed this?I noticed this using the command pmap under solaris it operating system
every time I test reconnecting to database I go and check the memory used by the application before after attepmting to reconnect:
/usr/proc/bin/pmap [myapp pid] | tail -1
If I'm using normal connection then the memory will be increased by 100KB. If I'm using the OraclePooledConnection class then the increase will be something like 500KB. Again this is if still there is a problem connecting to database. If connection to database is okay then no memory increase at all.
This memory is not
garbage collected so application hangs.
Then it isn't a java problem. When java runs out of memory it throws a out of memory exception.Well I'm not saying it is a java problem for sure. I suspect that it might be oracle oci8 driver problem. I would appreciate if anyone can help in specifying teh source of the error.
I tried
similar behaviour with the oracle thin driver and
things went fine. There was no memory leakage.
I would really appreciate, if you can help me in this
since I can't use the thin driver because of failover
limitations.
I don't understand that last sentence at all.What I mean here is that instead of using the oci8 driver to connect to database I used the thin driver and kept everything else the same. I simulated the faliure to reconnect to database and based on the pmap command observations there was no memory leakage.
I want to know what is needed to be done in order to get a normal behavior once using the oci8 drivers.

Cannot connect using oracle jdbc oci8 driver

I am using Oracle 8.1.5 JDBC oci8 driver, but when try to connect, always got ERROR: java.lang.UnsatisfiedLinkError:make_c_state

Hi,
Here is the snippet code from oracle,
// You need to import the java.sql package to use JDBC
import java.sql.*;
// We import java.io to be able to read from the command line
import java.io.*;
class JdbcCheckup
public static void main (String args [])
throws SQLException, IOException
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
// Prompt the user for connect information
System.out.println ("Please enter information to test connection to the database");
String user;
String password;
String database;
user = readEntry ("user: ");
int slash_index = user.indexOf ('/');
if (slash_index != -1)
password = user.substring (slash_index + 1);
user = user.substring (0, slash_index);
else
password = readEntry ("password: ");
database = readEntry ("database (a TNSNAME entry): ");
System.out.print ("Connecting to the database...");
System.out.flush ();
System.out.println ("Connecting...");
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@" + database,
user, password);
System.out.println ("connected.");
// Create a statement
Statement stmt = conn.createStatement ();
// Do the SQL "Hello World" thing
ResultSet rset = stmt.executeQuery ("select 'Hello World' from dual");
while (rset.next ())
System.out.println (rset.getString (1));
System.out.println ("Your JDBC installation is correct.");
// close the resultSet
rset.close();
// Close the statement
stmt.close();
// Close the connection
conn.close();
// Utility function to read a line from standard input
static String readEntry (String prompt)
try
StringBuffer buffer = new StringBuffer ();
System.out.print (prompt);
System.out.flush ();
int c = System.in.read ();
while (c != '\n' && c != -1)
buffer.append ((char)c);
c = System.in.read ();
return buffer.toString ().trim ();
catch (IOException e)
return "";
This code can be run without specifying a TNSNAME connection string, as the oci8 jdbc driver will take localhost as default.
OR
Only specifying the TNSNAME is enough, i.e. edit %ORACLE_HOME%\network\ADMIN\TNSNAMES.ORA file and locate the XXXXX.WORLD entry in the file. This is the TNSNAME entry referred to.
Without TNSNAME entry you can re-run,
%ORACLE_HOME%\jdbc\demo\samples\oci8\basic-samples> java JdbcCheckup
Please enter information to test connection to the database
user: system
password: manager
database (a TNSNAME entry):
Connecting to the database...Connecting...
connected.
Hello World
Your JDBC installation is correct.
Hope that helps.
Best Luck!

I used dbping tool from iplanet and could define a new connection and connect successfully,
But trying to use the existing connection always fail with the same 'MissingMethod' exception.
Can someone help?
Thanks a lot

Here is your problem:
jdbc:oracle:oci8:@eundev:EUNDEV
the last part is wrong. Driver will see the EUNDEV as password. After @ , just specify the tnsName that you have, no " : "
you do have a property called "password" already.
It should be something like this:
jdbc:oracle:oci8@eundev

Help - Could not load 'oracle.jdbc.driver.OracleDriver ...

I'm using oci8 to connect to the Oracle database.
URL: jdbc:oracle:oci8:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(PORT=1527)(HOST=testhost)))(CONNECT_DATA=(SID=fnoe2pa)))
When I tried to start the weblogic server, I got the following errors:
Can you suggest what I should do next (step-wise)??? Thanks, Bobby

If this is a type-4 JDBC driver, it could occur if the JDBC

If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)

This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL

3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.

Most likely, the OCI libraries could not be loaded.
Before continuing down this path, is there any reason
why you want to use an OCI based Driver as opposed to the
all Java Oracle thin driver ?There is indeed a valid reason for my choice.
I am currently connecting to the Oracle "Rdb" 7.0 database (located on
VMS) - not Oracle Oracle.
The SQL Service software we're currently using is version 7.1. This
version works well with the OCI8 driver (when connecting to the
database from Windows NT). This version of SQL Service however does
NOT work for the THIN driver (unless we upgrade the SQL Service to
version 7.1.5.5 - which we're not prepared to do so because it is not
stable enough from our previous test/trials). SQLSRV Version 7.1.5.5
works for THIN driver but it will result in uncommitted
transactions/unresolved connection/stopping of listener issues and
there is a need to restart the service from time to time. Oracle has
since confirmed that this is a bug that they have yet to resolve...
So we have to stick to OCI8 (THICK) for the time being. I would really
appreciate it very much if you can tell me the various OCI libraries
that I need to load (in terms of WebLogic Server config file settings
etc..).
By the way I have already installed the Oracle 8 client software on
the NT server (where WebLogic Server is) and I have also set up the
relevant SID (using the Net8 Assistant) that points to the Oracle Rdb
database on the VMS. I have also tried using SQL*Plus to connect to
the database and I can connect properly to the database. But WebLogic
simply doesn't seem to load the software.
Help...

Oracle OCI Driver

Hi all,
We have a setup accessing an Oracle-database (9.0.1 and 9i) from a
java program using an Oracle thin driver like this:
jdbc:oracle:thin:@host:port:sid
This works fine. Now we wanted to try the OCI-driver for speed
comparision (mainly bypassing socket communication).
jdbc:oracle:oci8:@host:port:sid
This didn't work. We use the classes12.zip for Oracle 9.0.1. downloaded
from OTN. The error is:
java.lang.NoSuchFieldError: OCIEnvHandle

Any suggestions on what to check up on?
Also I'd like to know whether it is correct that the Oracle 9 driver uses oci8?

Hi Elango,
One cannot connect to the database using host:port:sid when using OCI driver. Strange.
It has to be a TNSname or a url .
jdbc:oracle:oci8:@(description=(address=(host=myhost)(protocol=tcp)(port=1521))(connect_data=(sid=orcl)))I tried this (adapted to our database of course) and also (because we have tnsnames.ora setup too):
jdbc:oracle:oci8:@tns_name
With the same effects. ('tnsping tns_name' works)
I think the problem lies somewhere else. The system doesn't even try to actually connect
before it throws that exception. Some driver incompatibility, I guess. But I don't know,
what I did wrong or where to look. Especially that 'Exec format error' is suspicious,
because we'd like to use 64bit if possible.
Also, for when this starts to work, I'd like to know how to make sure there is no socket
connection being used. I vaguely remember something like
jdbc:oracle:oci8:@beqlocal:tns_name
but I don't know the exact syntax. There are several database on that machine, so just
beqlocal wouldn't be enough, unless it also uses the environment-variable
ORACLE_SID

JDBC OCI8 driver for Redhat linux 6.1

I have oracle 8.1.5.0.1 Enterprise server loaded on RedHat linux 6.1 and i am trying to access database through jdbc. When I am trying to execute one of the compiled class say Employee.class provided in the JDBC samples directory using OCI* driver it is coming up with an error libocijdbc8.so can not open shared object file: no such file or directory. This libocijdbc8.so file can not be found on the disk. Can some one please provide me leads where can find this driver? ar Oracle's website or somewhere else?. Any help in this regard will be greatly appreciated.
Thanks

One more thing, I tried this with both jdk1.1.6_v5 and jdk1.1.8 and also i have class path pointing to $ORACLE_HOME/jdbc/lib/classes111.zip file. and the code is

Issue encountered when Login as sysdba role using Thin Oracle JDBC Driver

Hello all,
we are now considering to use Thin oracle JDBC driver to create database in our project, but we met one issue when we tried to connect to oracle as sysdba role using Thin driver, and it throws java.sql.SQLException: Io Exception: SO Exception was generated, I have found some tips on oracle jdbc website and it says :
How do I connect as SYSDBA or SYSOPER?
The only way to do this is to use the Properties object when connecting, rather than specifying the username and password as strings. Put the username into the "user" property, and the password into the "password" property. Then, put the mode into the "internal_logon" property. Something like the following:
Properties props = new Properties();
props.put("user", "scott");
props.put("password", "tiger");
props.put("internal_logon", "sysoper");
Connection conn = DriverManager.getConnection (url, props);
When connecting as SYSDBA or SYSOPER using the Thin driver, the RDBMS must be configured to use a password file. See "Creating and Maintaining a Password File" in the "Oracle Database Administrator's Guide".
So, i did execute orapwd command to create a password file and also set remote_login_passwordfile=execlusive in my initxxx.ora initial parameter file, however, when i tried to connect, it failed.
private static void createEmsdbDatabase(){
String url = "jdbc:oracle:thin:@localhost:1521:";
StringBuffer sqlStatement = new StringBuffer();
sqlStatement.append("create database xxx");
sqlStatement.append("maxdatafiles 254 ");
sqlStatement.append("maxinstances 8 ");
sqlStatement.append("maxlogfiles 32 ");
sqlStatement.append("character set UTF8 ");
sqlStatement.append("national character set UTF8 ");
sqlStatement.append("DATAFILE 'c:\\oracle\\xxx\\system01.dbf' SIZE 18M REUSE ");
sqlStatement.append("logfile 'c:\\oracle\\xxx\\redo01.log' SIZE 2M REUSE, ");
sqlStatement.append("'c:\\oracle\\xxx\\redo02.log' SIZE 2M REUSE, ");
sqlStatement.append("'c:\\oracle\\xxx\\redo03.log' SIZE 2M REUSE ");
try {
DriverManager.registerDriver(new OracleDriver());
Properties props = new Properties();
props.put("user", "sys");
props.put("password", "password");
props.put("database","xxx");
props.put("internal_logon", "sysdba");
Connection conn = DriverManager.getConnection(url, props);
Statement statement = conn.createStatement();
statement.executeUpdate(sqlStatement.toString());
statement.close();
conn.close();
} catch (SQLException e) {
e.printStackTrace();
But what made me puzzled a lot is if i use OCI driver, it did work great, why??? guys, anybody knows, please give me some tips, thanks in advance.
regards,
Kaixuan @ Shanghai

clarify my question in detail:
Step 1 : create password file using orapwd command
Step 2 : create database instance using oradim command
Step 3 : login using sys as sysdba to startup database, e.g startup nomount pfile='...\initxxx.ora'
Step 4 : create database.
java code showing below:
private static void createEmsdbDatabase(){
String url = "jdbc:oracle:thin:@localhost:1521:";
StringBuffer sqlStatement = new StringBuffer();
sqlStatement.append("create database xxx ");
sqlStatement.append("maxdatafiles 254 ");
sqlStatement.append("maxinstances 8 ");
sqlStatement.append("maxlogfiles 32 ");

issue was met here, when i tried to login as sysdba using sys, and in my java code, i use Thin driver, it then thrus exception, but when OCI driver is used, it works great, i don't know why.
that is, when i use "jdbc:oracle:oci8:@" as database URL and then properties.put("database","xxx"), it works great. but, when i use "jdbc:oracle:thin:@localhost:1521:" as database URL and then properties.put("database","xxx"), it failed. hopefully, i have clarified my question clearly. thanks.

Problems when using absolute() on Oracle JDBC driver

Hi all,
I wrote some codes using JDBC to access a remote Oracle server. After got the resultset, I attempted to use absolute() method to move to a specific row index and got an error. Could anyone please help me to find out the cause and the solution?
Thanks in advanced,
** We have used driver package jdbc/lib/classes.zip in ORACLE 8.1.7
** The total of records in HEFKE000 table > 1000;
** The coding is following:
String url = null;
Connection conn = null;
ResultSet rs = null;
Statement stmt = null;
String query = "select * from HEFKE000";
String dbName = "HE_MI";
String hostName = "NTTD";
String userName = "HOKEN";
String passWord = "manager";
String dbDriver = "oracle.jdbc.driver.OracleDriver";
//Load the Driver
Class.forName(dbDriver);
//get connection
url = "jdbc:oracle:oci8:@NTTD";
//url = "jdbc:oracle:thin:@" + hostName + ":1521:" + dbName;
conn = DriverManager.getConnection (url, userName, passWord);
// It's faster when you don't commit automatically
conn.setAutoCommit (false);
// Create a Statement object so we can submit
// SQL statements to the driver
stmt = conn.createStatement();
// Submit a query, creating a ResultSet object
rs = stmt.executeQuery(query);
// Get the ResultSetMetaData. This will be used for the column headings
ResultSetMetaData rsmd = rs.getMetaData ();
// Get the number of columns in the result set
int numCols = rsmd.getColumnCount ();
int i;
if (rs.next() == rs.isFirst()) {
rs.absolute(100);
boolean more = rs.next ();
while (more) {
// Loop through each column, getting the
// column data and displaying
for (i=1; i<=numCols; i++) {
if (i > 1) {
System.out.print("|");
if (rs.getString(i) == null)
System.out.print("");
else
System.out.print(rs.getString(i));
output.println();
// Fetch the next result set row
more = rs.next ();
** The error:
Exception in thread "main" java.sql.SQLException: Invalid operation for forward
only resultset : absolute

Thanks. However, after changed the codes as your suggestion and ran again, I got the following error:
Exception:
java.lang.OutOfMemoryError
<<no stack trace available>>
A note is that, the 'select * from HEFKE000' statement would get around 1,5 millions of records. So, the 'out of memory' above is for client side or for server side?
Thanks,

Problem with jdbc- Oci8 driver

Hi there,
I am using oracle client of version 8.1.5 and jdk1.2.2, classes12.zip in the classpath of my NT.
I can able to establish the database connectivity using thin driver..
But for Oci driver, it is not working..
I have given piece of code below.
Class.forName
"oracle.jdbc.driver.OracleDriver");
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci8:@netlink","hris8","hris8");
netlink is TNSentry in TNSnames.ora
I am getting Dr.Watson error and which is saying that access violation error..
null

Thanks for your reply,
So i need to install oralce client version
8.1.6 or 8.1.7; so that i can work out Oci 8 driver with jdk1.2.2 ...
Is it so?
