OCI Vs 100% Pure JDBC Drivers..
Hi there,
Can anyone explain, why would I consider using OCI native code drivers in Java applications instead of the 100% Pure JDBC driver ? IS OCI driver faster/ has more features ??
thankx
Gautam
Hi ,
The only dis-adv with OCI driver is that it is not compatible in other platforms , since it uses native code and requires a client installation of oracle.
But the advantages over power them ,
Its very much faster and has a lot of added features .,
You can refer to the oracle documentaion.

Upgrade 10G to use 10G thin jdbc drivers- OCI
This is wierd...
If I upgrade 10G app server to use the 10G thin JDBC drivers, and set up a data source to use the thin drivers, is there any way that I could score a[b] ORA-01010 invalid OCI operation error when I'm not using an OCI driver?
Anyone else seen this...again, it makes no sense...You can not and should not use JDK 1.2 with 8i drivers.
If you want to use JDK 1.2 drivers, download the 8.1.6 SDK
from external site.
Please, please, please READ the FAQ at www.oracle.com/java/jdbc

On the Oracle Tech Net site, it seems I can only download
JDBC drivers for NT or for Solaris... no linux...
Where can I get Oracle JDBC drivers for 8.0.5 for Linux?
Thanks!
Greg
nullThe thin driver will work from either download (classes111.zip)
since it is pure java. There is no OCI driver for Linux that I
know of.

Fees related to Thin JDBC drivers
We have Oracle8. Are the JDBC drivers included. If not, how much will we have to pay to get these drivers.
If they are freely available for download, I would like to have the URL.
ThanksJDBC Drivers should come with the Oracle database (all versions - from Personal Oracle to the Enterprise Edition).
From the OTN Downloads area (Select a Utility or Driver => Oracle JDBC Driver) several different versions of the JDBC driver (and of the SQLJ translator) are freely downloadable.
You will get the JDBC thin drivers (all Java platforms) and the OCI drivers for Solaris and NT. Other platform-specific OCI drivers (if any) should come as part of the Oracle database distribution. -

JDBC DRIVERS 와 NLS 의 관계
==========================
PURPOSE
JDBC drivers 가 지원하는 National Language Support (NLS) 에 대해서
알아봅니다.
JDBC Drivers 는 NLS 와 conversion 을 지원합니다.
JDBC Drivers 는 NLS 를 지원합니다. 오라클이 지원하는 character set
을 가진 database 라면 어떤 character set 에서라도 data 를 입력, 출력
할 수 있습니다.
ASCII 나 ISO-Latin-1 databases 의 경우에는 conversion 이 일어나지
않아 간단합니다.
NLS database 라고 하면 일반적으로 non-ASCII database 나
non-ISO-Latin-1 databases 를 의미 합니다.
( 예를 들어 Japanese, Korean 같은 ..)
JDBC program 에서는 database 가 어떤 character set 을 사용하던지
간에 target character set 은 항상 Java unicode (UCS-2) 입니다.
이것은 CHAR 과 VARCHAR2 data 에 한합니다.
RAW data 의 경우에는 conversion 이 일어나지 않습니다.
JDBC OCI Driver 와 NLS
JDBC OCI 의 경우 database 가 특정 character set 을 가지고
client 또한 고유의 character set 을 가집니다.
client 의 character set 은 database 와 다를 수 있습니다.
client 의 character set 은 install 시에 결정되며,
database 의 character set 은 database 생성시에 결정됩니다.
따라서 JDBC driver 는 적절한 conversion 을 해주어야 합니다.
JDBC OCI driver 가 character set conversion 할때 다음 3가지
사항들을 고려 합니다.
- database character set 과 language
- client side character set 과 language
- JAVA unicode (UCS-2)
JDBC OCI 를 사용할 경우 data 가 server 에서 client 로 전달될때
database 의 character set 으로 전달되게 됩니다.
data 는 client 에 도착할때 까지는 conversion 이 일어나지 않습니다.
client side 에 도달하면 표준 Oracle conversion routines 을 사용하는
OCI routines 에 의해 database character set 에서 client character set
으로 변환되게 됩니다.
JDBC 개발자들은 각각의 database character set 에 따라 각각 다른
conversion programs 을 사용하는 것이 아니라 한가지 character set 에서
Java unicode (UCS-2) 로 변환하는 한가지의 conversion routine
사용하도록 했습니다.
오라클이 지원하는 많은 수의 언어들을 encoding 하게 해주는 이 character set
는 UTF8 (Oracle 7 에서는 AL24) 입니다.
NLS_LANG 에 따라 data 변환은 다릅니다.
NLS_LANG 이 설정이 안되어 있거나 ASCII 나 ISO-Latin-1 character set 로
설정되어 있는 경우에는 JDBC OCI driver 는 ISO-Latin-1 나 ASCII 로 부터
Java 내에서 UCS-2 로 직접 변환합니다.
ISO-Latin-1 나 ASCII 로 부터의 변환은 최적화되어 있습니다.
NLS_LANG 이 ASCII 나 ISO-Latin-1 character set 이외의 character set
으로 설정되어 있을 경우에는 driver 가 client 에서 NLS_LANG parameter
를 UTF-8 로 변경합니다. 이것은 JDBC program 에 한하며, system 의
NLS_LANG 환경에는 영향을 주지 않습니다.
이것은 자동으로 일어나므로 user 는 해줄일이 없습니다.
OCI 는 NLS_LANG parameter 값을 읽어와 data 를 database character set
에서 UTF-8 로 변환해 줍니다. 이 변환은 C 에서 이루어지며 Java 에서
이루어지는것이 아닙니다. 그 이유는 Java 내에서 이루어지는 변환의
회수를 줄이기 위해서 입니다.
그리고 난 후에 JDBC OCI driver 는 UTF-8 data 를 UCS-2 로 변환합니다.
JDBC Thin Driver 와 NLS
JDBC thin 에서는 UTF8 로의 변환이 server side 에서 일어나게 됩니다.
그러나 만일 database 가 ASCII 나 ISO-Latin-1 character set 를 사용하고
있다면 server side 에서의 변환은 일어나지 않습니다.
client 에서 JDBC driver 는 UTF8 을 UCS-2 로 바꾸게 됩니다.
==================================================================
주의: OCI 와 Thin drivers 는 모두 동일하게 NLS 를 지원합니다.
==================================================================
Server Driver 와 NLS
server 에서 실행되는 JDBC code 가 database 에 접속할때
JDBC Server dirver 는 database character set 를 기반으로
character set 변환을 수행합니다.
모든 Java programs 의 target character set 은 UCS-2 입니다.
JDBC Server driver 는 ASCII 와 ISO-Latin-1 character sets 만을
지원합니다.
database server 에 있는 Java VM 이 ASCII 와 ISO-Latin-1 character set
만을 지원하기 때문입니다.

License of Oracle TimesTen JDBC Drivers
Dear all
I have looking into my installation directory, but i cannot find the license file for the jdbc drivers for Oracle TimesTen:
The drivers are the following ones:
- ttjdbc5.jar
- ttjdbc6.jar
Could anybody tell me where i can found the license?
Regards
CarlosThe TimesTen JDBC drivers are covered by the same softwarer license as the rest of TimesTen; i.e. the standard Oracle software license agreement. To distribute any component of TimesTen you will need a suitbale distribution agreement with Oracle, sorry.
Note that TimesTen JDBC drivers are not pure Java drivers. They are a JDBC/ODBC bridge and rely on a properly installed and configured TimesTen ODBC client in order to operate.

Does JDBC Drivers in Oracle9i support SSL connection
Hi everybody,
I have to access to some information in Oracle9i DB throught SSL connection from Oracle OCI clients. I would like to know if the administrators have to use an specific datasource and OCI driver. I have to verify if Oracle 9i JDBC drivers support SSL connections.
Thanks you very much
RosaIn order to use SSL, you would need to install and configure Oracle Advanced Security both on the client and on the database. If I recall correctly, this is an additional cost option if you have the Enterprise Edition database.

Hi,
My aim is to write a simple Java program that connects to the
Oracle Database and displays the data from a table. But I dont
have any JDBC Drivers for oracle.
So, I have downloaded the Orcle JDBC Drivers from the Oracle
Site under the section below :
Download the drivers NT
Oracle8i 8.1.7 JDBC Drivers for use with JDK 1.2.x for NT.
It is an Zip file which consists of so many files/directories..
Where do I place all these files.
And how do I create a Datasource which connects to the Oracle
database and can be used in Java Program?
Please help me in acheiving this simple task with detailed
Instructions. ( I can achieve the above task using JDBC:ODBC
Drivers, but now I want use the latest Drivers)
Also where can I download the Type4 Drivers for Oracle?
Thanks in Advance,

OAS and using JDBC-drivers from EJB
Hi.
I have a problem with accessing the database from EJB-components
deployed to OAS 4.0.8. The database is 8.1.5-version. I'm trying
to use a connection exactly like it is documented in OAS-EJB-
documents, the connection string looks like this:
Connection conn = DriverManager.getConnection
("jdbc:oracle:jts8:@ora8i");
And this is the error that above sentence it generates:
"Sub Protocol must be specified in connection URL".
The DAD(ora8i) is created in OAS.
Now, I don't even know if this uses JDBC/OCI or thin since the
documented connection-string doesn't contain that information. I
quess it must use OCI-drivers, at least I should use them and
they should be installed with OAS.
So:
* I should use only jts-enabled JDBC-drivers when developing EJB-
components, is this right?
* How can I connect to the database (from OAS 4.0.8 to Oracle
8i), the string please?
Thanks,

How come Oracle's web site only has downloads for NT and Solaris. Where do I get the latest JDBC driver for Linux?
You should be able to use clases111.zip from AIX or NT with your
Linux client, just copy the file, and add it to your CLASSPATH.
I'm using classes111.zip from AIX (8.1.5) on NT and Win95
clients.
This will work for the thin client, the oci8 needs SQL*Net
(and some more support libs.) installed to work

Thin JDBC Drivers Insert Strings Incorrectly
Can anyone confirm or deny this.
I've downloaded the latest Oracle 8i JDBC drivers. If I create a table:
CREATE TABLE Moo (stringCol VARCHAR(10) NOT NULL);
and I try to insert an empty String into Moo.stringCol, the JDBC drivers try to insert Null instead! Yet if I try and insert a String of one character in length, it inserts it correctly.
Clearly it would seem the JDBC drivers are at fault.
Anyone come across this?No, the drivers are performing correctly. In Oracle, an empty string in a varchar or varchar2 column is considered NULL. Regardless of what protocol or language you use to access the database, this will hold true.

3rd Party Access 2000 JDBC Drivers
Wondering if anyone can recommend or rate any 3rd party MS Access JDBC drivers - I am running an app using Tomcat 4.0.2, on Windows 2K, currently using the JDBC/ODBC bridge from Sun, looking for something a little more specific and reliable for my app - company willing to spend the $$ to get something good.
Thanks!
Geoffhi Geoff ,
I would recommend you the aveconnect driver from Atinav. It is a type 3 driver, and is a reliable and nice implementation. We have been using it for quite some time now and our developers here have seen it to be quite efficient and good.
this url may help you..

an error blow:

Can anybody tell me why,thanks!Weblogic has been designed for nannies...
I've developed a application which uses internally my own jdbc-driver.
After months of really hard work on tomcat (the application works fine) I've tried migrate it to weblogic.
But ...
In weblogic seems mandatory to put the jdbc drivers out of the war!!!. Brilliant!!!
If I move the driver out, I need move the 50% of the application out, also!
If I move part of the application out, nothing works, because... �are the class loaders distinct?. And I'll need to do a lot of extra work because one day one weblogic architect had a great great inspiration.
In the future I'll suggest to my customers to run and not stop when they listen the WEBLOGIC word.
