(applet,thin driver): IE works, appletviewer not; driver location?

Hi,
there are a lot of questions around this topic but I couldn't find a specific answer to this:
I programmed an applet under WinNT (connection to Oracle 8i thru thin driver) and keep the Oracle drivers in the ..\Ora8i\jdbc\lib\ place (ZIPped), classpath set correctly.
The applet works fine in IE on my local machine, but not in the appletviewer (it can't find the driver class). Without applet-specific part it works fine using 'java ...'.
I use the suggested 'import oracle.jdbc.driver.OracleDriver' statement.
2nd question: since this applet is supposed to run on a webserver (and not only my local machine...), where do I place the driver (class or whole zip-file?) and how do I tell the main class / applet where to look for it instead of Ora8i\jdbc\lib\ ?
Thanks for any help!!

There's a fair amount of fiddling you can do with packets sent over the network by SQL*Net, but that requires the OCI driver. The thin driver is writing out Oracle's wire protocol which isn't publicly documented.
The OCI driver is going to be faster in general than the thin driver, and you're going to have more flexibility to optimize its network traffic.

JSP Not Working with Thin Driver

My JSP is not working with Oracle thin driver but it is working with Oracle OCI driver.
From my jsp i am calling a stored procedured and passing 170 parameters to the procedure. This JSP works with Oracle OCI Driver configured as thrid party drivers in iAS6.0 SP2, but not working with Oracle Thin Driver configured as third party drivers in iAS6.0. My thin driver JDBC Connection URL is as follows:
jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = MAPDBI01)(PORT = 1521)))(CONNECT_DATA =(SID = MAPS))).
I have to give this URL because my production server deployment consists of iWS4.1 SP5 and iAS6.0 SP2 in different solaris boxes and Oracle 8.1.7 Database server in another Solaris Box. There is a pool of proxy servers between iAS6.0 box and the oracle box.

Wim,
I'd really appreciate it if you could provide some sample code. A complete, small, simple java class that I could copy and try out would be wonderful -- if it's not too much trouble.
Thanks heaps (in advance :-),
Avi.

Sql_trace does not work for Java app using Oracle JDBC thin driver

Hi,
I'm using Oracle 8.1.7. I enabled sql trace at instance level by setting sql_trace and timed_statistics to true in init.ora. I restarted the db instance. I wrote a stand-alone java application which used Oracle JDBC thin driver(classes12.zip) to make a connection to my db instance, do some select statements, and close the connection. There were no trace files generated in the folder specified by udump_dest variable. However, if I used sqlplus or dba studio, I saw trace files generated. Has anyone got Oracle sql trace work for JDBC calls from java apps.
Thanks in advance!

Applet Oracle thin driver on IE: NO Suitable Driver

Dear Sir, Happy New Year to you and Shailesh Sir.
I used IIS server under Win 2k, applet is perfectly working from anywhere, using thin driver in Netscape but not in IE 5.0 or 4.0.
Following are the exceptions for IE:
111) The code under 111-applet folder of Oracle:
Driver name: JDBC driver oracle.jdbc.driver.OracleDriver
Connection String : jdbc:oracle:thin:student/student@cmmserver:1521:cmmora
Exception:
No suitable driver
class java.sql.SQLException
102) The code under 102-applet folder of Oracle:
Driver name: JDBC driver oracle.jdbc.dnlddriver.OracleDriver
Connection String : jdbc:oracle:dnldthin:student/student@cmmserver:1521:cmmora
Exception:
No suitable driver
class jdbc.sql.SQLException

oracle.jdbc.driver.OracleDriver is in ora81/jdbc/lib/classes12.zip
Include classes12.zip in your classpath.

How JDBC thin driver protocol works ???

Hi,
I'm having some problems, I think, with an application that I developed using Java (j2se 1.4.0), the system performance is very good (1500 msec per query) unfortunelly my customer want's more than that.
So I've been working in some optimizations against the code that execute the query, after reading the JDBC Developers guide some modifications were made at the code, altering Statement to PreparedStatement, the time down to 1200 msec, yet too much.
Then I tried another aproach, I've put an Sniffer on the LAN and sniffed the packets that flow to the database from the applet when I executed one single PreparedStatement resulting this table:
--- Time: 2002-10-21 14:16:06
Src IP Dst IP sent recv
TCP 10.0.0.122 1895 10.0.0.119 1525 55 0
TCP 10.0.0.122 1895 10.0.0.119 1525 0 51
TCP 10.0.0.122 1895 10.0.0.119 1525 133 0
TCP 10.0.0.122 1895 10.0.0.119 1525 0 40
TCP 10.0.0.122 1895 10.0.0.119 1525 0 127
TCP 10.0.0.122 1895 10.0.0.119 1525 40 0
The query executed:
select trim(cidade) nome, trim(coduf) uf from cacidade where codcidade = :1
Where codcidade is the Primary Key.
I'm using defineColumnType in the PreparedStatement.
Anyone knows how can I reduce the number os packets that the thin driver put in the network ?
That packets sent and received depents in each other ?
How are implemented the TTC over Java sockets by Oracle?

How are implemented the TTC over Java sockets by Oracle? You should post this question on the JDBC forum here on OTN. Someone there may have more insight into the internals of the jdbc drivers.
Hope this helps,

How to set SunOne IDE to work with Oracle thin driver

I am new to the SunOne IDE. I am trying to use the JDBC wizard to generate a form to work with an Oracle table. I want to use the ORacle thin driver but I am not sure how I can tell the IDE where its located. Can someone help? Thanks.

In the explorer window select "RUNTIME".(Bottom of window tabbed pane)
Expand "DATABASES"
Expand "DRIVERS"
Scrolldown and you'll see Oracle thin - click on that and set properties.
Then right click "Oracle thin" click "connect using..."
From here/there you should be able to view all tables you have access to view..etc.

Could not connect through thin driver

I am trying to connect to database through thin driver but getting the following exception :
Io exception:The Network Adapter could not establish the connection
java.sql.SQLException: Io exception : The Network Adapter could not establish the
connection at oracle.jdbc.dbacess.DBError.throwSqlException(DBError.java:168)
but I am able to coonect to the database through the oracle client and also through the odbc bridge driver.
also I am able to connect to other oracle database but not the particular.
pls if anyone can help ,suggest me what could be the possible error and solution to it.
Thank u.

I am not sure what is your URL parameter in the getConnection Method !
Check if the it is
jdbc:oracle:thin:@<ip-Add of server>:<port no>:<SID>
e.g.
jdbc:oracle:thin:@10.173.110.70:1521:cpmnc
Hope this works !

AFAIK the Oracle drivers still don't work with JDK 1.4, switch to 1.31 and they should be fine.

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.

ORA01002 with Oracle thin driver - not with JDriver

Hi,
I use weblogic 5.1 SP10. I was using the weblogic JDriver to create a connection
pool for my entity beans with BMP. I switched from the weblogic Jdrivers to using
the Oracle thin driver (classes12.zip) for my connection pool. Now i get a ORA-01002
(fetch out of sequence) for my ORACLE 8.1.6 SELECT FOR UPDATEs. I can solve this
by - explicitly setting autocommit to false for the connection. This is within
in the EJB transaction.
Why I have to do this with the Oracle thin driver and not with the Weblogic JDriver
Any thoughts on this are appreciated !

From this I assume that you know what you are doing but I have to ask, are you
using the TxDataSource to obtain the connection in your BMP entity beans? If
so, I would talk to support...

Hi Robert,
I am using the TxDataSource in the workout.properties file.

You need to remote onto the server and go into start->control panel-Administration-> ODBC (or sometimes start->administration->ODBC) and set up ODBC connections . Make sure you set them up on the system tab, then you should see them in EAS. I don't remember, b ut don't think you need to restart the Essbase servise for them to take effect

9.0.1 JDBC thin driver not logging

Does anyone know how to get the 9.0.1 thin JDBC driver to do logging,
the way the 8.1.7 driver did (via DriverManager.setLogStream)?
Looks like OracleLog has a constant compiled in
that prohibits any logging, and its class javadoc states:
"This facility is only enabled in the debug zip/jar file. " However, there's only
one driver (classes12.zip)
available for download at http://technet.oracle.com/software/tech/java/sqlj_jdbc/htdocs/solsoft.html.
I can't find any "debug" zip file available for download.
Has anyone found a 9.0.1 thin driver that logs correctly?
Thanks very much,
