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.

Can 11g client connect to 10g server?

I am very new to Oracle, so hope this isn't too basic of a question. I thought I saw something through my searches where the clients were backward compatible to older versions of the server. Will this work, 11g client connecting to a 10g server?
I have a custom windows app that uses the Oracle client to pull data from an Oracle server at another location and pushed the data into a MS-SQLExpress database for a local cache to be used during th day. I do not have the source for this custom app or the time to re-create this custom app. We just installed a new Windows 2008 R2 (64bit) server and I just need to get the client back on the new server so the custom app will work again. The old server was running 8.1.7 client, but going to 64bit OS I want to use a more current client to avoid issues with 32bit/64bit compatibility problems.
I am downloading the 11g 64bit client now, but want to make sure I'm not wasting my time and need to get a different client. Please advise.
Thanks!

In general, yes, you can use a later version of the client to connect to an earlier version of the database and vice versa. But that only generally works for a few major releases. Unfortunately "10g" and "11g" are somewhat ambiguous-- both could be referring to one of two major releases.
Metalink 207303.1 is the client/server interoperability matrix. If by 11g you mean 11.2 and by 10g you mean 10.1, the 11.2 client will not work with a 10.1 database. If the client is 11.2 and the database is 10.2, it should be at least 10.2.0.2. If the client is 11.1, the database should be 10.1.0.5 or 10.2.0.2 or higher.

TNS-12518: TNS:listener could not hand off client connection, XE 10g/WinXP

I've installed Oracle XE 10 on Windows XP. When I browse to the database homepage, I get this in listener.log:
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=8080))(Presentation=HTTP)(Session=RAW))

I don't think it is shortage of resources (just rebooted). I put "DIRECT_HANDOFF_TTC_LISTENER=OFF" in listener.ora .. no luck. I removed the listener.ora file altogether ... ditto.
What else could cause this?

How to track IP's of clients connecting to DB server through Apps Server

My Application server address is like http://192.220.0.75:7779/forms90/f90servlet form=TEST.fmx&userid=@abc
I can connect to Apps server from any computer using explorer with this address .
for auditing when I connect to db server through Apps server then my audit table detect only server IP- 192.220.0.75 each time but when I connect by oracle DS or toad then my audit table detect each computers defferent IP address.
how can I detect different users and IP addresses connecting to database server using apps server instead of apps server IP?

You can try to use WebCache event_log, this one will show your clients IP or you can uncomment UseWebCacheIP ON in httpd.conf file, so you ensure that the access_log show the ip of the user and not of the server.
Greetings.

New to Oracle SQL : Cannot connect to the server

I am familiar with MySql and find that some of the syntax are different. I would like to get certified in Oracle DB and would like to know whats the best approach to take. Where do I start? I downloaded 10g on my mac os and not sure what to do next. How do i run the Oracle DB now that it is installed?
Also, It recommends trying Oracle Enterprise Manager Database Control via http://host.domain:5500/em/. I used my ip address for the host but but what is the domain? I typed for eg http://0.0.0.0:5500/em/ but i get the following error message
Safari can’t connect to the server.
Safari can’t open the page “http://0.0.0.0:5500/em” because Safari can’t connect to the server “0.0.0.0”.
Thanks for any help you guys.

...If you have installed Oracle Server in your computer then you should see the menu item added in the Start -> Programs path. Look for "Database Control - <db_name>" or something similar. When you click on it, it opens up the browser with the correct URL. If the browser doesn't show up anything still, then check if the service is up. Start -> Settings -> Control Panel -> Administrative Tools -> Services. Ensure that the service "OracleDBConsole<db_name>" has "Started" status.
Try using your full computer name for "host.domain". Right click "My Computer" on the desktop -> Properties -> "Computer Name" tab -> Full computer name. The Start menu item mentioned in the earlier paragraph does this for you.

How to make the client connect to the server at the command prompt?

I found this code on IBM's website, it was a training session on servers and clients using java.
The code compiles fine and the server seems to start up properly when I use java Server 5000. I think whats happening is the server is running and listening for a connection on port 5000.
When I try to run the client I get the following error.
Exception in thread "main" java.lang.NoSuchMethodError: main
I see a start() method but no main. As far as I know, applications should all have main, it seems as if the person who wrote this kinda confused applets with application. Not that I would really know what happened.
If you have time, could you tell me if there's an easy fix for this? I would love to have this client/server working if it isn't too much trouble. As I have looked all over the net for a free client/server applet that will actually let me see the java code and none of the free ones do allow getting to their source.
Most of them allow you to customize them somewhat but also have built in advertising that can't be removed.
This is the closest I have come to finding one that lets me look under the hood. But alas it doesn't work out of the box and I don't know what to do to fix it.
Heres the code: Server:

Oracle AS and Oracle 9i Client on the same server

Hello,
We have a Window 2000 server with Oracle 9i Client. A number of applications running on this server relies on Oracle 9i Client. Could I install Oracle AS on the same machine without causing any problems to the applications using Oracle 9i client?
Thanks
Slava

Oracle software is multi home aware - which means you can install 10 different Oracle products and versions, each in its own unique Oracle Home directory, and switch between and run all 10 different products - even at the same time (assuming sufficient resources on the platform).
You cannot "+consolidate+" different Oracle Homes - it is an unwise thing to do. The Oracle Universal Installer (OUI) has the means to determine when installing a new product, whether or not you have the option to install into an existing Oracle Home.
And with OUI you also have the means to uninstall products in which case you can remove the corresponding Oracle Home from your platform.
Note though that despite multiple homes, certain configuration files will be shared (e.g. +/etc/oratab+ on Unix systems). In such a case you may need to manually update such a configuration file after removing an Oracle Home from your system.
Oracle XE sports its own installer (setup.exe on Windows) - so it does not use OUI. But it is multi-home aware - and can co-exists with other Oracle products in their specific Oracle Homes.

Do you have all of your parameter files set up correctly?
You need to have a hsora file in the hs/admin directory for ioi for instance, initioiDB.ora. In this file you need to set up your hs init parameters. This is an example of what's in one of mine:
HS_FDS_CONNECT_INFO = Mapics
HS_DB_NAME = MAPICS
HS_DB_DOMAIN = WORLD
HS_FDS_TRACE_LEVEL = ON
The you need to have an entry in the tnsnames.ora file in the network/admin directory for hsodbcxtrad. The sid should be set to ioiDB.
You can find documentation on how to manage heterogenous services in the online documentation.
Managing Heterogenous Services Using Generic Connectivity
Hope this helps

I have been trying to set up a database link between Oracle and SQL Server, currently both on the same Windows NT machine.
I managed to create the link as follows:
CREATE PUBLIC DATABASE LINK ioi
CONNECT TO IOItest IDENTIFIED BY mba

The link is created successfully.
I then try to run a query and get the following error :

Can we restore oracle 11g RMAN backups to 10g server

Hi,
I have RMAN backups (full backup)of oracle 11g database. My server was suddenly crashed due to hardware failure.
We have another Oracle 10g server. Is it possible to restore RMAN backups of 11g database to Oracle 10g server???
Thanks

I don't have 11g server ready with me. The other server running oracle 10g and I dont have rights to install oracle 11g on the 10g server. So I can not test the RESTORE/RECOVER commands.
If anyone had experience in the past, please let me know whether we can RESTORE RMAN backups of 11g database to oracle 10g server...
Thanks

I don't think tomcat supports the ejb-ref portion of web.xml. If you're using ejbs your best bet is to use a web container within a J2EE implementation.

Finding the clients connected to a server

Hai Friends,
I am doing a project in grid computing. I have developed a socket program for the client and server side using java and multithreading.
I want to know the number of clirnts connected at a particular period of time and also the IP addresses of the client.
Can anyone please suggest us the code for doing that.

Create an object that describes each client. Something like:
public class Client
    private Socket socket;
    private WhatEver whatEverDataYouNeed;
    ...whatever methods you need...
}When a client connects create one of those objects and store it in a suitable data structure, e.g. LinkedList. When a client disconnects remove from list.
There should be a method in Socket that gives you the IP address, see the javadoc for Socket.

Echo to all clients connected to NIO server

I am writing a NIO xml socket server that uses NIO.
My model implemensts a producer / consumer system where client connections are accepted and processed by a specified number of worker threads.
I would like to be able to broadcast a message to all clients that are connected to the server.
Opinions / suggestions I am sure that this is quite a common type of functionality.
Kind Regards

Accendia server is implementing a callback mechanism that allows the server to notify the client.
This is not broadcast, you would have to call each client (www.accendia.com). For real broadcasting use datagram or multicast sockets (depends on different factors) on both client and server in addition to the sockets used as part of the NIO server.

Accendia server allows the server side to invoke callback objects on the client. You can't do real broadcasting, though, you would have to iterate through all client connections. See if it helps:

If you need real broadcasting you can use datagram or multicast sockets on both the server and client side.

Lion clients connectivity to lion server 10.7.4

i have been having issues connecting Lion clients running 10.7.4 to the mac mini running lion server 10.7.4
The issue started after i did a clean install of lion server. I configured everything correctly by downloading server admin tools, turning on the open directory, and creating a master open directory for the server. i then created both a test account and a generic account to see if the accounts will work when a client trys to connect. The lion clients had no issue connecting to the server but when the Mac would restart, a red dot would come on the side saying all network accounts are unavailable. I am not sure what is happening and yes i have checked the DNS portion and everything is in working order.

Can you boot into the Recovery HD? If so, run both
Disk Repair and Repair permissions on the OSX volume.
Also, if you have a bootable clone of your previous install,
try booting into it and see if the problem persists.
If you have a Time Machine backup, try to restore to
a point before the upgrade.
