Oracle 8i - force connection with protocol encrytpion

Hi, I would like all client connections via JDBC to my
oracle database to use protocol encrytion this way
a hacker can not see the data thru a sniffer.
Is it possible ? and how?
Thousand thanks

If you have added the Olite40.jar file to the IDE_CLASSPATH setting in the jdeveloper.ini file, make sure you restarted JDeveloper after editing the ini file.
Also, make sure you specity 'Olite40.jar' not 'olite40.jar' (watch the case of the archive file name).

WebLogic 9.2: Oracle: Can longer connect with a Good Data Source

Hi;
I have WebLogic 9.2 set up on my computer as a development tool. Yesterday I was able to connect to the test database on our test server with the JNDI/Database resource "abc" just fine.
For some reason, it simply stopped working this morning.

Hi Joe;
I appreciate you taking time to answer my question.
By client do you mean my JRE? I one JRE set in my JAVA_HOME, and two in the weblogic install. How can I tell which is WebLogic using? So, you are basically saying make sure my Oracle JDBC drivers wherever they are in WebLogic should match what I have in my JRE?
I'll give that a shot when I get into work tomorrow.
I am puzzled because it has been working fine for weeks and I haven't changed anything.

How can I use oracle 9i to connect with my jsp

Hi,
I have a question with my a little final year project. I have been install oracle 9i on Win2000. I also install apache and tomcat on Win98 and it works properly. I am trying to use jsp to develop my homepage and it can be connect with my oracle to retreive information. I'm wondering what steps/configure I need to do?
Could anyone tell me about this? Thanks
Amy

Amy,
You can look at [url http://otn.oracle.com/sample_code/tech/java/jsps/ojsp/dbaccessjdbc.html]this sample. It provides step by step explanation on how to connect to database using JDBC from a JSP. We use Java Beans in the sample. Download the code and have a look at it.
Hope this helps.

i have 11 g installed on the server computer , and we can only use it only on browser , I have a global.asax as a file in my dot net project in which connection string is written but i m getting error , something like ora10cc .
first i do not know , which odac version i have to download i have a link for this ,
http://www.oracle.com/technetwork/database/windows/downloads/index-101290.html
but which version exactly , this page is so confusing, for oracle 11 g, and visual studio 2008 which version will be perfect
and then where the dll will be there. after getting the setup, Is i need to install that setup?
one more confusion , where i have to install that odac , on my computer system . or on the server side system , I just need that dll file ,,

sumbody pls help me
i m getting problem in at from 3 days
If u can then contact me , on [email protected] , otherwise reply me here
thanks in advance
regards Nimish Goel

The file at the top of that link should work fine with Oracle 11g.
I would start trying to get the client to work outside of Visual Studio, first. That way you can localize your issues.
Once you get the Oracle client connected to the Oracle server, then uou can start working on Visual Studio.
As for where to install it, I'd say start with your computer. I'm not sure how you do your development, but that would probably be a good place to start.
You may want a different download for the web server as I assume you wouldn't need the special Visual Studio tools on it. But yes, it will need whichever Oracle provider you choose installed on it as well.

Oracle 9i lite connection with a Java Client

Hi,
I would like to connect a Java Client developed using PersonalJava edition for PDA with an Oracle 9i lite version which is also on PDA.
I would like to know is it possible to connect such a client (Java) using some JDBC drivers on PDA.
if yes please do suggest a suitable driver and some input tips as to how to connect a GUI developed in Java directly to Oracle on PDA.
I am not too sure whether some web/application server is required in the whole setup.
because in N-Tier Architecture we have a middle layer of Application /Web servers in between a client screen(usually a Browser) and Database.
but I am not aware weather it is possible to directly connect Java Swing or Client application as I mentioned above developed using Personal edition with a database using only some driver software but no other middle ware component in between.i.e forming a 2 tier client server model.
please do let me know your valuable suggestions at [email protected]
thanks,
Ashish

I connect to the database through the same user that created those tables. Do I still need a public synonym ?

Oracle8i connectivity with php4 in winXP

i have installed oracle server 8i and php4.3.4 as a module of apache web server in windows XP. for oracle connectivity i have uncommented the php_oracle.dll and php_oci8.dll in php.ini file in the windows directory. and made the extension_dir=c:/phpwin/extensions/. but still oracle is not connected with php cause it can't recognize the ocilogon function.
i donot install client (oracle).Will i install client?
if i do then how i connect it to the server or configure it to connect with php?
and if i don't then how i configure oracle? In this connection i want to add that i have found in the oracle folder oracle/network/admin there is tnsnames, sqlnet etc. do I need to configure it?
Every time it is said that set environmental variable. how can I do that?

PHP needs some Oracle libraries either from a Client or Database
install. If you already have the database installed on the machine
with PHP and Apache then you don't need a separate Oracle client
install.
Load the script:
<?php
phpinfo();
?> and check what environment variables are found. Is the Oracle bin
directory in PATH?

Error connecting with Few versions of Oracle

I wrote an MFC based application in Visual C++ to make the connection with Oracle Database. ADO Control is used to make connection. Following is the Connection String:
"Provider=MSDAORA;User Id=Scott;Password=Tiger;Data Source=(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))(CONNECT_DATA =(SID = edox)));"
I am able to connect with few versions of oracle like 8.0.5.0.0 and 9.0.1.1.1
But few versions are not accepting this connection string. Like Oracle 9i, Release 1.0.2. What could be the reason of this problem?
Another thing that noticed with 8.0.6.0.0 is that when i start the oracle service, and try to connect, it refuces connection, but next time it accepts the connection request...

Another thing i noticed is if i connect the SQL+ software, it continues working. But if i close the session of sql+, my other application stops working...Strange.

Difficulties connecting with oci8 to Personal Oracle 8 on Win98

After looking through responses to other similar difficulties posted, I still can't seem to get this working.
I have Personal Oracle 8 running on Win98 on a laptop. I'm using Sun jdk117 and trying to connect with oci8 because the thin driver won't work without a TCP/IP listener which I understand Personal Oracle doesn't support.
There's an entry in my PATH pointing to c:\jdbc where the oci805jdbc.dll file is, and an entry in CLASSPATH pointing to c:\jdbc\classes111.zip .
To start with I'm using a simple connect program which shouldn't do much more than make a connection and close it again (please see below).
The program compiles fine, but when I run it all I get is:
C:\apache\jserv11b3\servlets>java connect2
in main()
connect instantiated
in tryconnect()
going to attempt connect
java.lang.UnsatisfiedLinkError: no oci805jdbc in shared library path

I can't see any reason why there should be problems linking oci805jdbc.dll as PATH definitely has an entry pointing to the directory where it is located.
Doubtless I'm doing something silly, or I'm missing some essential configuration parameter.
Thanks for any helpful suggestions.
program code:
import java.sql.*;
class connect2
public int tryconnect()
throws ClassNotFoundException , SQLException
System.out.println("in tryconnect()");
/* Load the Oracle Driver */
Class.forName ("oracle.jdbc.driver.OracleDriver");
System.out.println ("going to attempt connect");
try
/* get the connection */
Connection conn =
DriverManager.getConnection("jdbc racle ci8:@laptop:1521:ORCL", "system", "manager");
catch (SQLException e)
System.out.println ("Database Connect Failed");
System.out.println (e.getMessage());

System.out.println ("connect instantiated");
/* Call the tryconnect. Returns 0 if success , 1 if failed */
int Csuccess = c.tryconnect();
if (Csuccess == 0 )
System.out.println("Successfully Connected");

Thanks for your kind response.
I'll have a look through the docs and see if I can find out how to get the TCP/IP listener running with Personal Oracle.
I've been trying to use oci805jdbc.dll from the jdbc80520-nt.zip download file.
Since the original post I've been trying to get the connection working with the Sun JDBC-ODBC bridge, but all I get is:

in tryconnect()

The java code is identical apart from:
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
and

The relevant entry in tnsnames.ora is:

Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? Difference between Enterprise and SE?

We’re seeing the following issue: sql - Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? - Stack Overflow (posted by a colleague of mine) and are curious to know if this behaviour is due to a difference between standard and enterprise, or could we doing something else wrong in our DB config.?
We have also reproduced the issue on the following stacks:
Oracle SE One 11.2.0.3 (with Spatial enabled)
Redhat Linux 2.6.32-358.6.2.el6.x86_64 #1 SMP Thu May 16 20:59:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
11.2.0.3.0 Standard Edition and 11.2.0.4.0 Standard Edition (both with Spatial enabled)
Microsoft Windows Server 2003R2 Standard x64 Edition
However, the SQL works fine if we try it on Oracle 11.2.0.3.0 *Enterprise* Edition.
Any help or advice would be much appreciated.
Kindest Regards,
Kevin

In my experience sdo_filter ALWAYS uses the spatial index, so that's not the problem. Since you did not provide the explain plans, we can't say for sure but I think yhu is right: Standard Edition can't use the bitmap operations, and thus it'll take longer to combine the results of the two queries (because the optimizer will surely split this OR up in two parts, then combine them).
BTW: when asking questions about queries here, it would be nice if you posted the queries here as well, so that we do not have to check another website in order to see what you are doing. Plus it will probably get you more answers, because not everyone can be bothered to click on that link. It would also have been nice if you had posted your own answer on the other post here as well, because my recommendation would have been to use union all - but since you already found that out for yourself my recommendation would have been a little late.

Oracle 10g ODBC driver with Windows 7 32 bit connecting to Excel

Hi Everyone,
I'm having an issue connecting to our oracle 10g database (64 bit system) from a 32 bit windows 7 installation running excel 2010/2007 using odbc drivers. Our excel spreadsheets worked without issue in windows xp.
In windows 7 I have been able to install the odbc driver via the following method:
1. Download the oracle 'basic' client and oracle 'odbc' client from www.oracle.com and extract the contents:
instantclient-basic-win32-10.2.0.3-20061115
instantclient-odbc-win32-10.2.0.3-20061115
2. Create a folder 'oracle' and place the instantclient_10_2 folder inside.
3. Ensure all the basic and odbc files reside in this folder.
4. Create a 'network' folder within instantclient_10_2
5. Create an 'admin' folder within 'network'
6. Create sqlnet.ora and tnsnames.ora files within the 'admin' folder:
7. Run 'obdc_install' within the instantclient_10_2 folder
8. Download and run the oracle odbc driver exe file from www.oracle.com (ORA10203.exe)
9. Go to Control Panel -> Administrative Tools -> Data Sources and create a new System DN
This allows excel spreadsheets connecting ONLY to oracle to function.
Unfortunately some of our spreadsheets connect to both a MySQL database as well as oracle. Spreadsheets connecting only to MySQL also function correctly, however, as soon as the vb associated with a spreadsheet includes a mysql call followed by an oracle call the spreadsheets fail. In Excel 2007 excel crashes completely everytime. In Excel 2010 the mysql data is generated, then when the script hits to oracle odbc connection there is a long pause, the oracle ODBC driver connect pops up requesting a username/password (this didn't happen in xp), then the data source selection pops up, then the username/password connect screen pops up again, and finally it fails with a runtime error '1004' General ODBC error.
If you look at the VB script it's failing at the Refresh BackgroundQuery statement in the ODBC connection block:
With Worksheets("Oracle1").QueryTables.Add(Connection:= _
"ODBC;DSN=Oracle_ODBC;UID=user;PWD=password;SERVER=ORACLE_LINUX;", _
Destination:=Worksheets("Oracle1").Range("A1"))
.CommandText = strSql
.Name = "Oracle1_data"
.FieldNames = True
.RowNumbers = False
.FillAdjacentFormulas = False
.PreserveFormatting = True
.RefreshOnFileOpen = False
.BackgroundQuery = True
.RefreshStyle = xlOverwriteCells
.SavePassword = True
.SaveData = True
.AdjustColumnWidth = True
.RefreshPeriod = 0
.PreserveColumnInfo = True
.Refresh BackgroundQuery:=False
End With
Does anyone know how to get around this? It's very important!!
Also if you try to edit the oracle ODBC connections in Control Panels -> Administrative Tools -> Data Sources, ODBC crashes 95% of the time.
Advice greatly appreciated!!

Well, here's what I'd check anyway..
1) get Process Explorer from http://sysinternals.com
2) make a mysql connection, get a list of dll's loaded (include the location and version columns in the lower pane output)
3) close that, then make an ora odbc connection, get a list of dlls.
4) close that, then make a mysql connection followed by an ora odbc connection, get a list of dlls
5) compare the lists of loaded dlls. In particular, the difference between #3 and #4, is there a dll dependency that gets loaded by oracle's odbc that comes from a different location when you've opened a mysql connection first?
May or may not help, but might turn up a difference to help point you in a direction.

1. Is the connection url correct?
"jdbc:oracle:thin:@PLANET:1521:ORCL" is fine.
2. Is the TNS listener started?
c:\oracle\product\ora10\bin> lsnrctl status
3. Is a firewall between client and database server?
Connection url with firewall would be different.

Cannot establish connection with Oracle database

Hello
This is the first time I use BOE server with Crystal Report to execute some tests, and one issue is blocking me now, and I am not even sure if this is the right Forum where I should post it.
I installed BOE server XI 3.1 SP4 on Linux machine (new installation), and then I uploaded some existing Crystal Report templates that are working fine on another BOE server. Those CR templates have to establish a connection with a remote Oracle database to get the data, and we pass all credentials for this purpose.
The first time I run my first test I received this error that I could not find anywhere on the web :
ErrorLog 2011 8 10 7:05:52.505 14215 356 (Administrator:82) (../reporthandler.cpp:12462): CReportHandler::buildReportViewerError: CSResultExceFailed to open the connection." FileName:"../reporthandler.cpp" LineNum:12458 ErrorCode:756 ErrorMsg:"Failed to open the connection.
{FBAD55EE-BEAF-11E0-BC1C-005056813A72}.rpt" DetailedErrorMsg:""
I believe that the CR was not able to establish the connection with Oracle, so I install Oracle Client on the same machine (test remote connection ==> pass), I set the ORACLE_HOME variable, and I edit the file <installation_home>/ bobje/java/CRConfig.xml to add the path to ojdbc14.jar, and finnaly restart the tomcat server. However I am still getting the same error message.
Is there any hint that can help me troubleshooting this issue?
Thank you

do the reports use native oracle connectivity or JDBC ?
what version of Oracle client did you install ?
was it 32bit or 64bit client ?
what your LD_LIBRARY_PATH variable set to ?
what does it say in the CMC when you look at CR report's DB properties ?
