ORA-01019 using XE Client OLE Provider, sqlplus works

Hello,
we use Oracle Express Edition and the Oracle XE Client software.On the Client (Windows 2000) we are not able to connect via OLE DB in some case. We tested it by placing and test.udl File on the Windows Desktop and configured and tested the Provider in there. When we click the TestButton, ORA-01019 comes up.
We tried the workaround, that is described in Metalink for the 10.1 Client (Setting the privileges on the Filesystem) but it doesn't work.
Any idea?
Frank

We tried the workaround, that is described in
Metalink for the 10.1 Client (Setting the privileges
on the Filesystem) but it doesn't work.
Any idea?Probably it's a workaround for normal Client not for XE Client which is based on Instant Client.

Can I use oracle client 10g express to work on oracle 11g database

I have installed an oracle DB 11g, I also installed oracle client 10g express edition to create users and tables. I noticed that the users I created can't connect to db with error message "Error java.sql.SQLException: ORA-01017: invalid username/password; logon denied" and tables I created can't access from my program. I get error message "Error java.sql.SQLException: ORA-00942: table or view does not exist". I start to suspect that client 10g express edition can't use with oracle 11g. Please help.
any suggestion is appreciated.
Thanks,

Hello Hemant,
you can't connect via the listener unless the database is up.You mean if we are going to connect @, db must be mount/open? We can'nt connect with @ in nomount state?
But i think we can connect in nomount using @, if we are having an SID name in SID_LIST of listener.ora?
Please correct me, if i am wrong.
Thanks and Regards

Instant client and Error while trying to retrieve text for error ORA-01019

For an older Windows app, I am exploring using Windows 32 bit IC instead of a full Oracle client installation:
IC 10.1.0.5 works fine for me but has the problem of not being able to connect if run from a folder containing parens (). ie., C:\Program Files (x86).
IC 10.2.0.3 gives the error "Cannot load any communication DLLs, network may not be installed". SQL+ works.
IC 10.2.0.4 gives the error "Error while trying to retrieve text for error ORA-01019". SQL+ works.
Does someone know why these three versions of IC would behave this differently on the same environment?
I have tried all sorts of things with ORACLE_HOME and TNS_ADMIN with IC 10.2.0.4.
Do you know which client version is the first to have the fix for the known C:\Program Files (x86) connect problem?
Or are their patches to IC 10.1.0.5 that I could implement ?
Any help or enlightenment would be appreciated.

The web server is not seeing the Oracle environment correctly. You need to set PATH to the instant client libraries. ORA_NLS33 is not used for Oracle 10g clients. Perhaps you have some library conflict with two versions of Oracle on the machine?
These may help:

Able to connect using sql developer, but not sqlplus or toad too; sqlplus error: ORA-12154: TNS:could not resolve the connect identifier specified
thanks in advance.

SQLDEVELOPER works since it use JDBC Thin & does not use tnsnames.ora
ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 [B]NEVER[/B] involves the listener, the database itself or anything on the DB Server.
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
TNS-03505 is thrown by tnsping & is same error as ORA-12154 thrown by sqlplus or others.
The lookup operation fails because the name provided can [B]NOT[/B] be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

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 ?

ORA-02074 Error and MS Data Provider

I have no idea where to post this kind of stuff, but let's give this a try and if it should be posted elsewhere, just let me know and I will move it!
My C++ developers use the MS Data Provider to access our 9i database. They call stored procedures to do the usual kind of application tasks. Nothing special. Many of the procs take parameters and insert/update/ or delete rows in tables and either ROLLBACK or COMMIT. No transactions are left pending at the end of any proc.
Well, some procedures yield a "ORA-02074: cannot ROLLBACK in a distributed transaction" error message when two conditions are met:
(1) The procedure has a non-conditional "ROLLBACK" AND
(2) The procedure has been WRAPped and is obfuscated.
This is quite odd. It seems that that Oracle code behaves differently when WRAPped! Creating the same proc not WRAPped functions correctly! The WRAPped procs run fine in SqlPlus, but when called from the data provider the procs croke!
Any ideas? I mean, rational ones?
Regards
Michael

The table does have a primary key (Cust_id), and like I said, I can update the data.
Thanks for the thought.... Any other ideas? Anyone have a datagrid sample that they want to share? (as long as it updates and you can add records to it).
Thanks - Jim

Oracle Client OLEDB Provider Installation

I need to call Oracle OLEDB Provider "setup.exe" once I complete installing our product (using Installshield). I tried all different ways to do this and I have absolutely no luck.
1. I tried calling LaunchaAppAndWait(SRCDIR^"disk1\\install\\win32\\setup.exe", "", WAIT) in OnFirstUIAfter event before SdFinishEx function and Installshield doesn't wait for Oracle Installer to finish its installation.
2. I tried to get window handle for each window created during Oracle Installation and waiting, this somewhat makes Installshield to wait but hangs once Oracle completes its installation and sequence of windows displayed can change during Oracle Installation if user clicks on back button which will make Installshield to hang.
Enable(STATUS);
SetStatusWindow(count, "Please wait... launching Oracle Universal Installer");
WindowName = "Welcome";
FindOracleWindow();
WindowName = "File Locations";
FindOracleWindow();
WindowName = "Available Product Components";
FindOracleWindow();
WindowName = "Summary";
FindOracleWindow();
WindowName = "Install";
FindOracleWindow();
WindowName = "End of Installation ";
FindOracleWindow();
hWnd=NULL;
Disable(HOURGLASS);
Disable(STATUS);
3. I followed knowledge base article w[i]Long postings are being truncated to ~1 kB at this time.

There is an Instant Client page on OTN http://otn.oracle.com/tech/oci/instantclient/instantclient.html as well as an Instant Client forum (Products | Database | Instant Client) where you may want to post any followup questions. I know you can use ODBC with the Instant Client, so you could use the OLE DB to ODBC provider. My hunch is that you cannot use the Oracle OLE DB provider with the Instant Client, but you're probably better off posting that question to the Instant Client forum for a definitive answer. If you can use OLE DB, the Instant Client documentation needs to be updated to mention that.

Installing Oracle OLE provider?

Dear All.
Is there a simple installer (MSI package or exe) that directly installs the Oracle OLE provider on Windows Systems?
I used the XEClient for 10g to do that but it installs too many things that I don't need, I only need my application to connect to Oracle database from another machine that doesn't have Oracle installed.
When I installed the XEClient, my application works fine for both 10g and 11g on Windows 2003, but when I tried my application on Windows 2008 using the same provider. I get an error citing that the Provider may not be installed properly.
I have searched the net and all I found directs me to install the Oracle Client which installs too much things, I am asking if there is a way to install only the required DLLs for the OLE DB provider without using the Oracle Universal Installer.

Unable to get 'InitialContext' using Java Client in Oracle App 10.0.2.0

Scenario & Problem Description: Unable to get 'Initial Context' using Simple Java Client in Oracle Application Server 10.0.2.0
I'm having an issue while I try to initialize the Initial Context for an EJB lookup from a simple Java Client [local lookup], but the same code snippet works fine when I try from Servlet. I have enclosed the Exception Stack Trace and the Code Snippet for your reference.

Note:
1. The user "ias_admin" & password "ias123" are the credential provided for the 'Admin' while installing the Oracle App Server and using these credentials I'm able to bring the Admin Console. Also, added new user 'guest/guest' - assigned this user to the 'admin' group ...
2. Since its a local lookup, there is no need to specify the credentials, but at runtime a dialog box pops up prompting to enter the 'userid/password' and when I enter the crendtials, I get the exception as stated. [In case of Servlet - EJB lookup, I'm not specifying any credentials]
Are there are any configuration parameters which I need to provide in any of the .xml? Could you please let me know the fix for the same.

Use of client dependent tables

Hi Gurus,
I have read many threads on difference between client dependent and independent data/objects etc.
But, someone tell me please, wheat exactly the 'Use or Advantage' of client dependent tables/data.
Thanks in advance.
V

HI,
The use of client dependent tables is that if data in one table of a particular client is updated then that data wont be seen in any other clent it provides a security to the data we retrict users with their authorizations in differen clients
When you log on to an SAP System, you log on to a particular client of this system. Any activities you carry out in the system are always carried out in one client. When you plan your SAP system landscape, you must consider which clients you need for which activities.
By assigning activities to be performed in a client, you give each client a particular role. This section describes the most important client roles.
Since you need to adapt the SAP software for your own business needs, each SAP system landscape requires a client where Customizing settings, and possibly ABAP Workbench developments, can be made. This client is known as the Customizing and development client, or Customizing client for short. The abbreviation CUST is used for this client.
Before you can use the Customizing settings and Workbench developments productively, you need to test them extensively for errors. Any faulty settings can seriously disrupt productive operations, and at worst, lead to the loss of productive data. The integrated nature of the various SAP applications means that there are many dependencies between the different Customizing settings. Even an experienced Customizing developer may not discover these dependencies immediately. The correctness of the settings can only be guaranteed with extensive testing. The client where these tests are made is the Quality Assurance Client, QTST for short.
A separate client is required for productive use of the SAP System. So that this client can be used without disruption, it is essential that no Customizing settings or Workbench developments are made here, and also that no tests are carried out. This client is known as the Production Client, PROD for short.
These three clients, CUST, QTST and PROD, are the central clients that exist in every system landscape. Standard system landscapes have precisely one client for each of these client roles.
We recommend that you make all your Customizing settings in a single Customizing client, and then use the CTS to transport them to the other clients.
We also recommend that you do not make any Customizing settings or Workbench developments in the quality assurance or production clients. You can make sure of this by making appropriate client settings.
In addition to the central clients, you can also set up other clients for other tasks. However, you must remember that each extra client takes up additional system resources (main memory and database space). They also need to be administrated. For example, you need to set up and administrate access authorization for the users, and also distribute any changes to other clients with the CTS. You must weigh up the advantages and disadvantages of setting up other clients.
Examples of other client roles are:
Development test client (TEST): Developers can use this client to test their Customizing settings and Workbench developments, before they release their change requests. In this client the developers can create test application data for realistic tests. If they discover errors, they can remove them in the Customizing client. A development test client is always set up in the same SAP System as the Customizing client. This means that any changes that are made to cross-client data in the Customizing client are also immediately visible in the development test client. Changes to client-specific data are copied from the Customizing client to the development test client using a special client copy function. The client copy function uses the unreleased change requests from the Customizing client to do this. The development test client is set so that you cannot make changes to Customizing data and Repository objects.
Prototype or sandbox client (SAND): You can use this client to test any client-specific Customizing settings if you are not sure whether you want to use them in this form. Any settings that you want to keep are then entered in the Customizing client. To prevent conflicts between the prototype client settings and real settings in the Customizing client, you cannot make changes to cross-client Customizing data and Repository objects in the prototype client. The CTS does not record changes made to client-specific Customizing data, and does not transport them from the prototype client. You can make sure of this by making appropriate client settings.
Training client (TRNG): To prepare end users for new functions that are to be transported into the production client, you can set up a training client. The users can use the new functions in this client with specially created application data. This client is set so that you cannot make changes to Customizing data and Repository objects.'''

Error connecting using JCO.Client: null in xRPM in EP

Hi Friends,
I am getting the following error in xRPM through EP
"Error connecting using JCO.Client: null"
I can't enter xRPM, but I can enter other Business packages iViews.
The problem is intermittant and user specific.
Can you pls provide any input on this ?
thanks in advance and warm regards
Purnendu

Hi Flavio,
Thanks for your reply.
The user is created both in the backend as well as in portal.
The roles are also ok.
The error I am getting only while accessing xRPM iViews.
If I restart the instance the error is removed. But it reappears again may be after few days.
This error is intermittant.
May be it is related to the Maximum Number of JCo connections in the WebDynpro configuration.
But I don't have much idea on that.
Can you pls provide any help on this.
Warm regards
Purnendu
