Connecting an Oracle 8i client to an Oracle 9 DB

Hey, my company just upgraded an Oracle8i instance to an Oracle9 installation. At first I was given link errors pertaining to an oci9 issue. I resolved that by patching my JDBC driver(classes12.zip).
Now I am told:
java.lang.UnsatisfiedLinkError: get_env_handle
at oracle.jdbc.oci8.OCIEnv.getEnvHandle(OCIEnv.java:70)
at oracle.jdbc.oci8.OCIDBAccess.logon(OCIDBAccess.java:359)
at oracle.jdbc.driver.OracleConnection.<init>(OracleConnection.java:252)
When I attempt to execute my java code. I patched classes12_g.zip with no change in behavior. Any suggestions?

Hello,
I am having much the same prolem. Am working with ColdFusion and IIS on an NT Server (that is the Oracle client) and an Oracle 8.1.7 database on a database server (Oracle server). Communication between these two machines worked fine with Oracle 7.3 client software loaded on the client machine and Oracle 8.1.7 on the server. Now I need to use the Oracle 8.1.7 client with Net8 and I can't get anything to verify. Here's what I've done.
I installed the Oracle 8.1.7 Client on the NT Server. I copied the tnsnames.ora and sqlnet.ora files over from the other client that is running on 7.3 client drivers. I would think that everything should work properly this way since 8.1.7 is supposed to be reverse compatible. What have I not done or done wrong?
I am aware that for Oracle 8i clients you can get away without using the SID in the tnsnames.ora file of the client. Is is a requirement that it is not used or can it still be used? If I choose not to use the SID where else must I change configuration files? any on the server?
I am kind of stuck so any light on the situation would be a big help. Thanks.

Connect Oracle 10g client to the Oracle 10g database behind a firewall

I need to connect an Oracle 10g client to the Oracle 10g database (windows server 2003 box) behind a firewall. I ran into this problem: Port redirection. Port redirection requires the Oracle client to connect to the database using a different port (usually a randomly selected TCP port) than the default or originally configured one. If there is no firewall between the server and the client, port redirection will not affect the actual connection. However, if port redirection does occur with the server behind a firewall, the client will be likely to suffer from a connectivity failure. The reason is simple: the newly assigned port based on port redirection is often blocked by the firewall. Such failures are not uncommon on Windows platforms.
I don't know how to stablished an unique TCP port.
I Enabled USE_SHARED_SOCKET on the Oracle database server, windows registry. Acording to what I read,that will force the server machine to share its port 1521 and thus all clients will stay on that port when connecting to the database. Noticeably, port redirection will not occur with USE_SHARED_SOCKET enabled, but that's true in oracle 8 or oracle 9. In oracle 10g this solution doesn't work.
I will apreciate any help about this. Please!
Thanks in advanced.

Three solutions in order of preference
1 Use Connection Manager on the server (only installed using a Custom Install). This will tunnel all traffic through a single port. It will also allow you to configure allowable nodes
2 Set up shared server to use a fixed port. Disadvantage: shared server has overhead and the number of connections is limited
3 Use shared_sockets. Disadvantage: when you stop the listener everyone is disconnected.

Oracle 8i Client install over Oracle 9i

I am trying to install Oracle 8i Client over top my Oracle 9i installation to support 8i EXP processess. It is appearing that it works (i.e. Universal Installer runs through everything like it is installing) but afterward if I run the Univ Installer to look at installed programs it is all still version 9.2 items and my migration of 8i to 9i still does not work. How do I force an overwrite?
Pretty sure I am not a P4 so that should not be the issue. Am I missing something on how to get 8i over top 9i?????
Thanks for any help,
Miller

If you want to install that software you have to do it in a different Oracle Home. If you want to export a database or part of it with the export uitility of Oracle8i client you will be able to do it without installing Oracle8i Client on Oracle9i.

Windows 7 64 bit, Access 2010 32 bit, Oracle 10G client 32 bit, Oracle database 10.2.0.4 64 bit

I am trying to connect to an Oracle 10.2.0.4 database from Windows 7 OS - 64 bit using
Access 2010 32 bit and Oracle 32 bit client version 10.2.0.1 installed on PC.
My user requires a 64 bit Windows 7 OS for other needs.
Oracle ODBC driver is 32 bit from Oracle 32 bit client.
In Windows 7 OS 64 bit, ODBC DSN setup software is located in:
C:\Windows\system32\odbcad32.exe for 64 bit drivers - all DSN types setup and
C:\Windows\syswow64\odbcad32.exe for 32 bit drivers - USER DSN setup
When I run the ODBC Data Source Administrator, I see the Version number is 6.1.7601.17632
I setup a User DSN using the 32 bit odbcad32.exe with a 32 bit ODBC driver.
Our Oracle TNSnames.ora file has our standard entries which have worked for years
(Windows 7 OS 32 bit and everything 32 bit has connected for years too)
So when I configure an ODBC User DSN and leave all the default settings and press the TEST Connection button, it says it works.
But when I open the existng Access 2010 database (which does connect to Oracle in a Windows 7 32 bit PC environment),
1. I go to Access External Data ribbon tab / Link to the Data Source by creating a linked table / press OK
2. I select the Machine Data source = to the USER DSN name / press OK
3. The Oracle ODBC Driver Connect Window opens with Service Name = USER DSN and User Name and it wants a Password
4. I enter the correct password and I get the following error message:
ODBC call failed
[Oracle][ODBC]{Ora]ORA-12154: TNS: could not resolve the connect identifier specified
(#12154) [Microsoft][ODBC Driver manager] Driver's SQLSetConnectAttr failed IM006 0
[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed (#0)
I have tried a quite a number of fixes:
I have gone into the PC registry and cleaned out most or all off the Oracle client keys and
reinstalled the Oracle 32 bit 10g client. It didn't fix the error.
I read about the Oracle instantclient-basic-win32-10.2.0.4.zip with ODBC modules but I have Windows 7 64 bit.
Anyone experienced a problem like this and have a fix?

Thank you for your reply.
I did not get to try it because after I entered my question, I did a lot more internet Googling.
I found this small comment:
“There's a known issue where you get a 12154 error message running 32 bit software on a 64 bit OS using client 10201, and
It should be resolved by patching the client to 10204, which you do by applying the 10204 database patch to it.”
I searched around for the 10.2.0.4 patch for 10.2.0.1 Oracle 32 bit client.
When I contacted my Oracle DBA to ask if he had that patch, he said that I should try the 11g 32 bit client on the Win 7 64 bit PC.
We have a 10.2.0.4 Oracle database but he said the 11g client should work fine.
I tried it and it solved the problem!
With so many settings, configurations and permissions involved in ODBC, I am inclined to think that I missed a setting but
it was a bug in the 32 bit client 10.2.0.1.
Solved.

Oracle 9 client connecting to 10g server

Hello,
Is it possible to connect an Oracle 9i client to an Oracle 10g server? Is there any known issues/problems with that?
Because I'm facing the issue that with the same application connecting to different oaracle versions, when I connect to the 10g I get some connection errors, I'm wondering if going back to client 9i and connect to a 10g server would be a good test.
Thanks in advance,
Lucas.

If Oracle knows little about connection pools it is true. If by changing the Oracle version some issues arise I wouldn't immediately discard the interoperability version issue.
In this case the OP faces probably a big issue. The application has to be upgraded and all the compatibility matrix revisited. The main problem when working with unsuported versions is that in case it has to do with a bug from 9i Oracle has limited support by means of the Extended Support option.
Does it have to actually do with interoperability, bugs or application configuration is something that cannot be accurately established after the partial information provided by the OP.

Executing an Oracle 9i Client Process from OAS 10g Java Application

Sorry in advance for the long post:
We have a piece of legacy software (Uniface.exe) that contains a good chunk of business rules for an existing system. Uniface client connects to an Oracle 10g database but requires Oracle 9i client libraries. Therefore the default Oracle home for a local machine running Uniface is set to the Oracle 9i client software location.
On the same machine we have OAS 10g (10.1.3.1) running a Java-based middleware product (J2EE). The Java code invokes the Uniface.exe client to run specific business functions. We have in our Java code Runtime.getRuntime().exec(cmd); where cmd is the Uniface.exe.
It appears that when the OAS Java program executes the Uniface.exe it is using the Oracle 10g client libraries from OAS instead of the Oracle 9i client libraries from the local machine's default Oracle home. When we run Uniface.exe from a Windows command prompt it works fine.
We have noticed that when running Uniface.exe from Java OAS uses its own Windows path and environment variables and does not honor the system path. We wrote a Windows bat script to explicitly set the Oracle home and system path to the 9i location and then run Uniface.exe but this doesn't seem to work.
Any ideas?

OAS sets the ORA_NLS33 environment variable to the OAS 10g home location (F:\Oracle\10.1.3.1\OracleAS_1\ocommon\nls\admin\dat). Setting it to my Oracle 9i client location (C:\Oracle\product\9i\ocommon\nls\ADMIN\DATA) appears to have solved the problem.

Hi,
Thanks for your reply, but your assumption is incorrect that I did not read the error message in the documentation. I read it many times, but could not correlate it with any wrongdoing.
solaris64:102b$ oerr TNS 12533
12533, 00000, "TNS:illegal ADDRESS parameters"
// *Cause: An illegal set of protocol adapter parameters was specified. In
// some cases, this error is returned when a connection cannot be made to the

// *Action: Verify that the destination can be reached using the specified

The above says that, illegal set of protocol adapters was specified...., I am using 'Local Naming (tnsnames.ora)' connection method and using TCP/IP protocol.

will i be able to connect oracle 8i clients on to oracle 9i server? is there any procedure for getting this connection.?
Please help

Look up the documentation for questions like this, under 'backwards compatibility'
You can't configure a client to work with a higher release, it works or it doesn't work.
This one will work.

Oracle 9 client / Oracle 12 Apps

Hi,
I launched the Enterprise Manager Console from the Oracle 9 client. While tried to connect to the Oracle 12 Apps using user SYSTEM/Manager, I got the following error even though I checked that the user SYSTEM has the SELECT ANY DICTIONARY privilege:
This application requires you have been granted the SELECT ANY DICTIONARY privilege. Contact your DBA to grant you this privilige.
Is this a know problem? Doesn't Oracle 9 client talk to Oracle 12 Apps.
Thanks,

Oracle E-Business Suite R12 comes with 10g. It is not possible to monitor a 10g database via 9i OEM console.
You can use Grid control, database control or the 10g java console for monitoring a 10g database.

PC session hangs when launch a query from Oracle 9i client to 10g database

I have a pc with Oracle 9.2.0.1.0 client installed. The database server level is 10.1.0.5.
When I launch a query from a client session the pc sesssion locks up and doesn't return any results. When I launch the same query from the database server , or from other pcs with Oracle client 10 installed , I get results almost immediately from the query.
The pc in question is running Windows XP Service pack 2. Other queries run fine from the pc.
Are there are any known issues with Oracle 9 clients querying an Oracle 10 database ?

Thank you for your reply. No, I must admit I didn't think of looking at the wait events. I will look at this as soon as I get a chance.
Thanks again for your suggestion.

Creating Oracle service in Oracle 8i Client for Oracle 10g XE

Hi all
We tried Oracle 10g XE on one Machine X - OS Windows XP Professional SP2 , It had earlier Oracle 8i Client. It installed fine. It is wonderful and easy to install.
Services started automatic for listner as well as OracleXE. We are able to create fresh Oracle Service in Oracle 8i client as well from the same machine X.
Problem
We are not able to create Oracle Service from another machine say Y which also has Oracle 8i client with the Oracle 10g XE service. We get TNS Problem error.
Kindly guide as to how to make oracle service with OracleXE from some other machine. OracleXE does not install networking tools.
Suresh Bansal

Oracle XE doesn't install assistants such as dbca or netca, don't expect to find them, XE is a compact and limited oracle edition.
>> We get TNS Problem error.
Could you please further detail the tns error you got?

Oracle.DataAccess.Client.OracleDataAdapter.Update not working

Hi
I am using the Oracle.DataAccess.Client.OracleDataAdapter from Oracle.DataAccess runtime version v4.0.30319. I set the SelectCommand and retrieve data from Oracle without any problems using the adapter to fill a datatable. I then use the DataTable.Clear method to remove all rows and fill it again from a different source using a different adapter. I use the Oracle.DataAccess.Client.OracleCommandBuilder to create the Insert and Update commands and finally I call the update command of the using the original adapter in order to update the Oracle database but nothing is updated.
I examine the table row count at each stage and also display the table using a DataGridView on a form and all appears to be fine. No exception is thrown so I am stumped.
I would be grateful for any suggestions as to what I am doing wrong.
My environment is VS2010 Express
Edited by: user1947494 on 04-Feb-2011 05:46

Hi,
Pretty tough without seeing any code. I really do not believe it has anything to do with the DataAdapter. What changed the specific row/rows after the second fill?
But, as a guess, take a look at the DataTable - Rows - RowState. Run the below(or some variant) method just prior to your update.
r,
dennis
       public static DataTable GetDataTableChanges_Modified(DataSet dataSet, string dataTableName)
            if (dataSet.Tables[dataTableName].Rows.Count > 0)
