HOW CONNECT TO ORACLE DB WITHOUT CLIENT MOTOR DB?

We have the ORACLE database in the UNIX server and the visual basic application in the NT server, and ths local machines connected.
The question is if it4s possible connect to the oracle the local computers without install the client part of oracle.
HOW? with the ODBC driver?HOW?
Thank you and sorry for my bad english,

Both the Oracle7 and the Oracle8 driver rely upon OCI and other parts of the Oracle client in order to connect and to do their job. I suspect that you may have been mislead into believing that the Oracle7 drivers could be downloaded and installed without the Oracle client by the different naming convention. Oracle7 ODBC drivers on the download page are listed as "Version 2.5.3.1.0 for SQL*Net 2.3 Windows" as opposed to Oracle8 drivers, which appear as "Version 8.1.7.3.0 for Net8 Client 8.1.7.0.0 (ODBC Version 3.51)". In Oracle7, the client software was named SQL*Net. In Oracle8 and beyond, SQL*Net was renamed to Net8 Client because it was clearer. Both refer to the client portion of the Oracle stack.
The error message you're receiving indicates that you're using the Microsoft ODBC Driver for Oracle, not an Oracle ODBC driver. It also indicates that the driver is failing because it is unable to call into the appropriate Oracle client stack to get any of its work done.
It's theoretically possible that an ODBC driver could be written that relied only on the Oracle wire protocol, which would allow you to install the driver without installing the Oracle client. This would be a generally monsterous undertaking, however, and I'm not aware of anyone doing so.

How to create Oracle Alert without metioning the email address in To Field

Hi,
I just wanna know that how to create Oracle Alert without metioning the email address in To Field.
Please help thanks.

If you don't enter anything in the email field, the alert email won't go out.
If you just want to test or if you plan to use the history, you can put a non-existant email there.
The alert will fire anyway.
Hope this helps,

Connect to Oracle using DAC Client in command line

Hi,
I'm trying to connect to Oracle DB using DAC client. I have configured a connection and tested, it works. When I use the connection to connect to the DB, its giving me an error
"unknown error, please start in command line mode and see the stack error"
How do I start in command line mode? Could anyone provide more information on this.
Thanks in advance,
RK

In oracle db, you can create 3 different types of users:
(1) create user x identified by pwd.
In this case the user x will connect to the db using username/password, in this example x/pwd
(2)create user ex identified externally;
In this case the user ex will connect to the db using "/" and the sqlnet.authentication_services parameter value in the client and server sqlnet.ora will be used in determining the oracle external authentication adapter to use. For oracle windows client/db server, this is by default set to NTS. NTS is the oracle windows authentication adapter.
(3)create user gx identified globally as 'CN=gx,O=Oracle';
In this case also the user gx will connect to the db using "/" and oracle ssl will be used to authenticate this user to the db.
It would not be possible to "Create user x identified externally" and connect with x/pwd.
Please clarify.
To help you in isolating the problem, I will need the following info:
(1)
what are you connecting as to execute your plsql. Are you using sqlplus ? How are you connecting (connect "/ as sysdba", connect "/", connect x/pwd) ?
(2)
what create user statement did you use to create the user
(3)
is odp.net and the db server on the same machine.
(4)
did you run your plsql from the same machine as the db server.
(5)
if odp.net is on a different machine than db server, did you try connecting from odp.net machine to db server, using sqlplus ?

How connect the oracle/Linux using ODBC

I want to connect the Oracle which install on Linux using Odbc, so my win98 machine can connect with the oracle.
But I don't know how to do ? May I install some Odbc driver in the Linux machine? and install odbc driver in my win98 machine?
my email: [email protected]

You may use this way:
1. Start on the server (Linux) Net*8 listener (lsnrctl start)
2. Install on the client (win98) Net*8 and configure it (Net8 Easy Configuration)
3. Install on the client (win98) ODBC drivers for ORACLE (by ORACLE or others) and configure it

Connectivity between Oracle database and client...

Hi guys,
I was asked to make a connection between oracle client and database via internet so that our clients can access the database from different parts of the country, and the data that is transmitted in the internet does not require security consideration. And I have successfully implemented this.
But later onwards they asked me to structure it in such a way so that clients must be able to select, insert, update and delete data offline, in case there is online connectivity problem.
So my question is, are there any possibilities in oracle to temporarily store data that are available in the oracle database to the client side and then later onwards transfer those datas once the clients are available online. Or are there any other alternative ways...
Additional Information - Client access the database through an application created by VB.
Please do help me on this project.
Thanks in advance for your help.

Asif.You probably should do a cost/risk analysis. Where you are headed might be able to be done (but it will require that the "clients" also have their own copy of the database) but it won't be easy and it certainly won't be cheap, either in initial implementation or in on-going maintenance. The alternative is to take a hard look at your network connections and see if it wouldn't be cheaper/easier to be able to ensure that it is reliable. Remember "the internet" won't break, it is highly redundant. If you have connectivity issues, they will almost certainly be in your own equipment and configurations, so your (your organization) will have the ability to address and fix any issues there.

How connect to oracle RAC via the RSG using port forwarding

Hi all,
I got a problem trying to connect to oracle RAC via the RSG using port forwarding .
on command line i sue to connect :
sqlplus 'username/password@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=firstRACnode)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=secondRACnode)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MSDP)))'
but when using port forwarding i forward the port 1521 to a local port and make ssh to the DB node ( as normal with other nodes but not RAC) but it never work with me for this situation
can any one give me a help ifthere is any changes should be done on the server side , or if any one faced such a problem and found a solution
Thanks,
Prathap.

Step 1
Create a ssh tunnel from local machine to remote db server. Forward any local port (should not be a well known port or a port in the private/dynamic port range) to connect to the database server's listener port. If the ssh tunnel is into the db server itself, the connection (port forwarding) can be on localhost (as the Listener should be listening on it). Alternatively use a public IP of that db server.
Example (using OpenSSH on Ubuntu 9.4):
Local server port 1527 tunneled to port 1521 on database server 192.168.0.100 using o/s account johnd (we connect to port 1521 on db server via 127.0.0.1):
ssh -X -f -N -o ServerAliveInterval=3 -L 1527:127.0.0.1:1521 [email protected]
Step 2
Run sqlplus and connect to the local fowarded port on localhost, using the applicable connection settings (e.g SID/Service Name, etc).
sqlplus scott/tiger@"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1527)) (CONNECT_DATA=(SID=orcl) (SERVER=dedicated)))"Note that the Listener must not hand our connection off - as the case would be when using RAC for example and connecting via a Service Name and not a SID. We need the Listener that accepts our connection to immediately hand us over to the database instance (via either a dedicated server or a shared server dispatcher process).

How to install Oracle 11 R2 Client (11.2.0.1.0) on OpenSuse 12-64

I would like to install the Oracle 11 client on OpenSuse 12-64, but when I try, the installer shows me a list of about 20 kernel parameters and packages that are incorrect. The packages required by the Oracle client are all older versions than the ones I have available.
I tried to install the latest client version (11.2.0.2.0), hoping it would use newer packages, but it just aborts with the error .../.oui: cannot execute binary file.
My Oracle 11g R1 database is running on OpenSuse 11.1-64 quite nicely by the way - I had no issues with packages there...
My questions are:
1. Can any one point me to the prerequisite list for the Oracle Client on Linux? Maybe I can find another Linux distro or OpenSuse version that works...
2. Can anyone suggest a way out of this mess that doesn't require installing a bunch of ancient packages?
Thanks in advance for any light you can throw on this issue...

You find the prerequisites in the installation guide, additional remarks may be in the patchset readme files:
http://docs.oracle.com/cd/E11882_01/install.112/e24325/toc.htm
If you have already newer packages, you may ignore the prerequisite checks. But OpenSuse 12-64 is not supported, no guarantee that it works at the end.

PLEASE .... Ask in an Oracle Java forum.
And read the documentaiton. There is a whole document devoted to doing that. http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/toc.htm has examples.
PLEASE ... do not ask product questions in a forum which clearly has a title saying it is devoted to assisting with download problems.

Connect to Oracle without Oracle Client in Windows?

Hi All,
Is there anyway to connect to Oracle DB without any installation of Oracle Product in Client?
I am using MS ODBC Driver Oracle but It need the "Data Source Name"
It seems that client machine do need to Setup the NET 8 Configure / Tnsname.ora
I can try to set any thing in Oracle Server, But want to minimize the effort doing on the client (Because there are many!).
I am using Visual Basic, WIN XP as client Platform. WIN 2K as Oracle DB Server.
Can anybody give me a hand. Thank you very much!
Eric Yuen

You'll need to install Oracle Client in the client machine. ODBC (or other) connections need OCI and Oracle Net layers.
The Oracle ODBC has a lot of dependencies, probably a thousand files. Unfortunately Client is pretty heavy... managewize also. So that's why you should develop "internet apps". :)

What are the contents of the SQLNET.ORA files ?(*Inside Oracle Developer*)
# SQLNET.ORA Network Configuration File: C:\oracledeveloper\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (LDAP, TNSNAMES, ONAMES, HOSTNAME)
DEFAULT_SDU_SIZE = 8761
(*Inside Oracle Database*)
# sqlnet.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
# This file is actually generated by netca. But if customers choose to

# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
Try to make a test:
Create an environment variable called TNS_ADMIN on your system, put the path for >>your TNSNAMES.ORA file and see what's happen.
e.g:
TNS_ADMIN=C:\Oracle\product\10.2.0\NETWORK\ADMINI'm sorry, I don't understand what you mean; how and where do I create an environment variable called TNS_ADMIN ?
I'm really not sure how to do this..

Problem while connecting to Oracle 9i server from Oracle8.1 client

Hi experts,
Could you please help in resolving the issue we are facing.
We are trying to connect from Oracle 8.1 client to Oracle 9.2 server and its giving error .This is on Linux environ ment.
FYI - we are getting errors when we changed the client as Oracle 8.1 instead of Oracle 9.2.
Pls suggest.
Thanks.

8i client can connect to the 9iR2 database, but beware wich client are you talking about, only 8.1.7 is compatible against 9iR2, even though you must be aware this is a no longer supported combination, which means in case you find a bug the only solution available is to upgrade the client version to 9iR2.
By the way, is there a real reason why you have to tie your client to 8i? Being 8i long ago dessuported.

Loos connection trougth a firewall between oracle server an client after 10 minutes

hello,
i do loos the connection between oracle server an client, because the firewall is between. The firewall will close non active connections an ports after 10 minutes. Only port of one site is clost after 10 minutes then, other site let the port open.
Shares to the the server do in not loos. Only connection to oracle. What can i do !!!!
Oracleversion ist 8.0.6
OS: Windows NT 4.0 and SP5
Thanks Frank

I had the same problem and I guess you are also hitting the firewall timeout problem... you can enable Oracle DCD (dead connection detection) by setting sqlnet.expire_time in $ORACLE_HOME/network/admin/sqlnet.ora appropriately. This solution I got from http://asktom.oracle.com.
I tried setting the expire_time to 50 minutes less than firewall time-out (which is 60 minutes) but it didn't worked, right now i am trying to figure out what else can cause the problem (I am using Oracle connection pool).... but I think above solution may solve your problem

Using Windows NT 4.0 client program connecting to oracle 8i linux server

Dear sir/madam,
Recently, I have successfully installed Oracle 8i in my red hat linux database server. I am disappointed because I can find client side Oracle Enterprise Manager in my linux server even I have installed client program in my linux database server.
Next, I install Oracle 8i client side program (windows NT/2000 version) in my Windows NT 4.0 server. I am still disappointed because I find Oracle Enterprise Manager console cannot work.
For Windows NT 4.0 Enterprise Manager, I have key in default administrator sysman, password oem_temp, and connect to mamagement server hangng (my linux database server). An error message display 'VTK-1000 Unable to connect to the management server hangng. Please verify that you have entered the correct host name and the status of the Oracle Management Server.'.
What's wrong with both Oracle 8i Management Server in linux database server and windows nt 4.0 server. Is there any problem for Oracle Management server console to connect to red hat linux database server?

I need to confirm that I will be able to connect an Oracle 11g R2 client (administrator install) to an Oracle 8i DB before i bother trying to setup such a scenario?Don't waste your time. It won't work. It simply results in an error.
I saw another thread that mentioned a patch level required for 8i to let the 10g client connect. Is there such a patch level needed for 11g clients as well?There is no such patch for 8i which allows 11g client to connect.
