Failed to connect Oracle database

Hi everyone,
Could you please help me to take a look at the error below? I tried to conect the Oracle database server via OLEDB from another machine, and got the error below:
Oracle client and networking components were not found. These components
are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3
or later client software installation. Provider is unable to function until
these components are installed.
I collected some solutions about this error, and tried rename the "OCIW32.DLL" on the machine, or modify the security of Oracle client folder, but in valid.
Who can tell me how to figure out it? And what should I do if i got the error like "Oracle client and networking components were not found"
BTW, the Oracle client installed on my machine is 10.2.0.3, my Oracle server is Oracle92.
Thanks
Linsay

As "orafad" explained, there is no OLE DB Provider in Oracle Instant Client.
You will have to use the regular client, available on http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winsoft.html
or similar.
If you don't have a support contract, you will not be able to get the 10.2.0.4 patchset.
I have no idea, but maybe Oracle Data Access Components for Windows (Oracle 10g Release 2 ODAC 10.2.0.2.21) can help you: http://www.oracle.com/technology/software/tech/windows/odpnet/index.html
Yours,

Failed to connect to database ONLY at the first time

Hi all, I installed Discoverer 10g version and I'm using an Application User to connect to the server where's the Db is installed.
Every time I try to connect to the server with Discoverer Viewer or Desktop I have a curious behavior....
ALWAYS but ONLY the first time I try to connect I have the following error :
- Failed to connect to database - Unable to connect to Oracle Applications database: invalid username/password.
If I try to re-connect again the second time it works perfectly !!....so, I think, there's nothing related with my .dbc file.
I tried also to write the ':' at the end of the user name....but it didn't work.
Into the pref.txt file doesn't exist a parameter like DefaultUserTypeIsApps to set....
Anybody have had the same "strange" behavior and found a solution or workaround ?
Thanks in advance
Alex

Thanks for your answers first of all !
At the end I found the solution looking at the Note:307167.1 on Metalink:
Discoverer Plus 10.1.2 Fails with ORA-1017 Error On First Login Attempt Then Works On Second Attempt
This note is very useful but into the solution the point 3 is not correct !
3. Modify the servername parameter to indicate the fully qualified servername.domain
Example:
An httpd.conf setting of: ServerName my_servername.mydomain.com should match a Discoverer Plus URL like http://my_servername.mydomain.com:7778/discoverer/plus
I had this problem both with Viewer and Plus...so instead to change the server name parameter (into the Apache/Apache/conf/httpd.conf file) with my complete URL (http://gnvdev.ote.gr:7779/discoverer/plus), I just write my right server name:
Example
After the installation of the Discoverer 1og server, into the httpd.conf file it was written automatyically: ServerName gnvdev
I just modified in ServerName gnvdev.ote.gr and both Viewer and Plus started to work perfectly at the first time.
I hope that this hint will be useful for you and others in the Discoverer forum !!!
Best Regards
Alex

It would appear that your archive location is full. If it is full, then try to get some more free space there by either deleting the old archives or specifying a different location.
I don't see any mention of a flash recovery area in the log message, but you may also want to confirm that you have reached your space allocated to the FRA.

Hi Justin,
I can connect the database where I use Oracle ODBC Driver. But Microsoft driver didn't work.
However, I can connect to the database where I use Microsoft driver in W2K (server side)...
Catherine
Can you connect with the Oracle driver? I'm not sure whether the Microsoft driver is supported against a 9i database (I have no information either way).

Re: copy access data into oracle with form builder 9i

Problem about using Oracle Form 6i to connect Oracle Database 10g express.

Sorry to interrupt all of you.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the paramater of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
After I google it, I still have no idea how to solve the problem. I would like to ask, could anyone mind providing some hints or solution to address the issues.
Thanks for your assistance in advance.

I don't believe the Net8 Easy Config (NEC) will create a compatible entry in the tnsnames.ora. I have Forms 6i running successfully against a 10g Express database, but I did not use the NEC - I created the entry myself. Here is the entry I use:
XE=
(DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=<<servername or IP address>>)
      (PORT=1521)
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=XE)
)Hope this helps,
Craig B-)

How to connect Oracle database into Visual basic 6.0

Hi. I am using Oracle I Enterprise version 9.2.0.1, I have a problem for connecting oracle database into VB. I use a ODBC to connect oracle database with VB. By testing connection. Message tells me that "connection successfully", but I can not have a record display in VB. It tells me that can not publish a connection with ODBC. Please tell me why

Are you using the Oracle ODBC driver? If so, which version?
Are you writing your own VB application? What API are you using-- ADO? Can you post the code that's making a connection and the exact text of the error message?

How to connect Oracle database from Active Server page

Hi
This is srinivas aluri
I have developed an application using ASP and MS-SQL7.
Now i want to port this application to Oracle 8i database
I have written my connection in seperate file called
connection.inc using SQL OLEDB provider
If i have to connect oracle database what will be my provider
and what is the exact code for this connection string
Here i am giving the code of SQL databse connection string
strcon= Provider=SQLOLEDB.1;Persist Security Info=False;User
ID=sa;Initial Catalog=prjdb;Data Source=servername
i have tried by changing the provider name from SQLOLEDB.1 to
OraOLEDB.oracle
but i could not able connect the database.
It is giving provider not found or not properly installed error.
But the same code is perfectly working from Visual Basic code.

it depends on configuration your going to choose, there are two ways--
- Using X/Open standards, for this
you have to make an entry of Resource manager in $TUXDIR/udataobj/RM file.
Then in UBBConfig file in GROUPS section u have to set Openinfo.
It also depend on which database you are going to use.
In your service now you need to call tpopen() API from tpsvrinit() function.
- Other possibility is, take an implicit connection using Pro*C or Pro*Cobol whatever platform you are using.
