Net config troubles...

We just set up a RHEL5 (Linux x86) server with Oracle 10GR2 (10.2.0.4). New database woriking fine.
Everything had been working fine until this morning when our SA made some network config changes on the server and bounced the server. It's also possible he may have made some changes in the dns.
Now, I can not get my listener to start or work since the server rebooted.
I get errors such as:
$ lsnrctl start
LSNRCTL for Linux: Version 10.2.0.4.0 - Production on 22-MAY-2008 13:47:30

TNS-12560: TNS:protocol adapter error
TNS-00507: Connection closed
Linux Error: 29: Illegal seek
Then, I check the HOSTNAME and can not ping it as the FQDN, but I can ping it by using just the abbreviated name.
Next, I checked the /etc/hosts file and it is nearly empty. Our SA has taken everything out of it except one line:
::1 localhost.localdomain localhost <ourservername>
Next, suddenly when I attempt to use GUI tools such as netca or even dbca, I am getting what look like java related errors.
$ netca &

Does anyone have any ideas? I think the first place that needs to be fixed is the /etc/hosts file, especially to include a line such as:
127.0.0.1 <ourserver.domain.com> <ourservername> localhost.localdomain localhost
Thanks in advance...

Seems as though the problem was with the /etc/hosts file.
Everything is working now after I asked my SA to put the basic information back into the /etc/hosts file. But strange thing is that he said he never took anything out of it. He used some kind of GUI tool that apaprently comes with our Redhat Linux.
I would give a lot of appreciation to have a good network and sys admin... but I guess that's not something our company values enough. Of course, maybe that's why our IT department has the highest turnover I've ever seen in my entire working career.

[b]Listener problem while configuring host string through NET config[/b]

Hi,
I am unable to create host string through Net config. While testing with userid/password, the test does not succeed.
The host string configured is known as PROCESS.
Net config error message while testing the connection is as follows:
"Connecting...ORA-12541: TNS:no listener

Did you check that the DB is up ? If not, then check it and, eventually, start it up.
If yes, then open a DOS window, set your ORACLE_SID, connect to Sqlplus as sysdba and type :

what is the result ?

Oracle Net config assistant not opening on windows.

Hi,
I installed Oracle 9i server on a windows XP machine on Friday, 2nd December. I configured the listener service, netconfig name and my application was up and running.
Today I wanted to make some changes in the listener service; but the net config assistant window is not coming up. New processes launch.exe and jrew.exe are starting in the background with each attempt to launch.
I made sure I am logged in as the same user which installed Oracle on the machine(having ORA_DBA privilages), gave the full control privilages to this user. But the net config assistant is still not opening up.
Could anyone help in this regard.
Thanks
Puneet

Has anyone of you seen this problem before??
Kindly reply asap.
Thanks

Hi,
Which service did you want to stop in "Services"? Actually, as I know, there's no such a "net config server" service in "Services".
Or did you mean this?

Net connection trouble: "No Ethernet cable connected or the device is not responding"

Hello
I have been plagued by a dropping Net connection for a couple of months, and as it has been getting worse lately I have tried to sort out the problem.
I have simplyfied my connection between the computers and the VSDL fiber modem by bypassing my AirPort Express and Ethernet hub and connecting the three computers directly to the built in ports on the modem.
Since I did that a new error message has started appearing on my Mac Mini, saying that I have no Ethernet cable connected to the modem, or the device is not responding. At the moment I have two of the machines connected, and the Mac Book Air seems to work without problems. There are lights on the Ethernet ports on the modem, and they are lighting up for the iBook even when the Mac Mini connection drops. When the Mac Mini connection drops the lights go off on its Ethernet port on the modem.
This seems to point to some sort of trouble with the Mac Mini. Is there a way to monitor what's going on? Can I use Terminal, for instace? It can't be the settings, and it cant' be the cable, so it must be related to the hardware I suppose. I am using DHCP to connect to the modem.
The connection drops arbitrarily, sometimes for long periods of time, and then comes back up again by itself.
Any ideas for trouble shooting etc?
Best
Hans Karlsson

Thanks again. Unfortunately, the problems are back again. Had a stable connection and connected the AirPort again. Everything was working fine. Then all of a sudden the connection dropped again today.h
Connected a LAN cable directly to my MacBook Air and got the connection to work immediately.
Took that cable and connected to my MacMini, again, connection came back immediately.
The AirPort (in Brigde Mode) is also connected, but gives me a blinking orange light, and the same "no cable or (modem) is not responding" message again.
I guess this must rule out hardware problems in the computers.
Ligth for the LAN cable port on the modem connected to AirPort is dead. Moved the cable to another port, light still dead.
Shut down AirPort Express, still same orange blinking light when I switched it on.
I now suspect there is something going on with the AirPort Express. Just bought it, and I had the same problem with it's predecessor, but...
Is there any way to trouble shoot the AirPort Express?
I can connect to it Wirelessly, But AirPort Utility says it has been removed from the Network. In the Network Preferences it says it has a self-assigned IP. For Network Settings I get green lights for everything except Network Settings, which gives me a yellow light. It also says the Internet connetcion is working correctly.
Indeed, when I made the direct Ethernet connection inactive I still get a working connection over WiFi, in spite of the blinking orange light on the AirPort and a yellow light for Network settings in Prefereces....
In the console things look normal:

WRT54GS- Browser Config Trouble

Hello all, this is my first foray into wireless networking, and it's been a real time. I've had all types of trouble. Possibly the most troublesome is how messed up the browser config/setup pages are. First, a screenshot:
http://img232.imageshack.us/my.php?image=browserconfig1oz0.gif
^Go Here for Pic^
As you can see, the navigation links are all missing, as well as most other text that explains what things on the page do. I have used the page before by connecting to the router with other computers succesfully, just not my main computer. I only have this one on the network. The other one of mine isn't used often, and is very old anyway. I do however, use the wireless network for my PS3. Obviously, what i'm saying is that i need to be able to use the config on my main computer, and i don't have room (or $$$!) to set up another. Thanks!

Thanks for the quick reply! I have reset the router, I have turned it off for 20 seconds, then turned it back on, I have even taken it back to the store for a new one. I forgot to mention that, and that the only page that I can access that works in the Port Forwarding Page, which is the main page that i needed to use the router. I have set up port forwarding for my PS3 (which, i'm not sure worked, because i'm getting all kinds of errors...i'll work on that after i fix THIS!)
Thanks!

Net Config Assistant won't save data?

Hi everyone! I'm not sure if anyone else had this problem, but whenever I run Net Configuration Assistant (10G), I can add a service name and test it sucessfully, but it never saves it to the tns_names.ora file. I have tried deleting this file and recreating it from the sample, but it still won't read. If anyone has any suggestions, I would greatly appreciate it.
Best Regards,
Brett Rosenblatt
F-Line Technologies

You have to hit "Finish" (or whatever the button is labled at the moment) once you've tested the service name before it will be saved. 99% of the time people have this problem, it's because they just exit once the test is successful.

Linux 9i install hangs at Net Config Assistant

I am installing 9i on Red Had 7.3 and the install program just stops when it gets to the Net Configuration Assistant. No err, but the process using up > 90% of the CPU. All the buttons on the install GUI are greyed out, so there is no way to go with the install of the rest of the tools.
In the install I also had an make err with OraHome1/ctx/lib/ins_ctx.mk.
Can you help me out with this?
Regards, Cary

I found the solution to the ins_ctx.mk issue at http://www.puschitz.com/OracleOnLinux.shtml. To cut to the issue, here is what worked:
Edit $ORACLE_HOME/ctx/lib/env_ctx.mk and go to "INSO_LINK =", add a "$(LDLIBFLAG)dl" to the line and save it.
Here is the full line with the added "$(LDLIBFLAG)dl" flag:
INSO_LINK = -L$(CTXLIB) $(LDLIBFLAG)m $(LDLIBFLAG)dl $(LDLIBFLAG)sc_ca $(LDLIBFLAG)sc_fa $(LDLIBFLAG)sc_ex $(LDLIBFLAG)sc_da $(LDLIBFLAG)sc_ut $(LDLIBFLAG)sc_ch $(LDLIBFLAG)sc_fi $(LLIBCTXHX) $(LDLIBFLAG)c -Wl,-rpath,$(CTXHOME)lib $(CORELIBS) $(COMPEOBJS)
After that hit retry in the error popup.
If you go to the page, the requied entry is bolded in the section where it has been added (its the third entry), making it much easier to see.
The page is an excellent guide to installing Oracle. However, it did not offer guidance to the Net Configuration problem, which I am also encountering. Anyone else have any info?

Pkg-config troubles

I need to install Mono, but I can't without pkg-config. The problem is, I can't install pkg-config. It configures well, but the 'make' is messy with all sorts of warnings about null pointers, and 'make install' doesn't do a thing.
What might be the problem?

ac3raven wrote:I need to install Mono, but I can't without pkg-config.
I guess you're trying to build it manually, but why? You can just use pacman -S mono to get mono.
ac3raven wrote:The problem is, I can't install pkg-config. It configures well, but the 'make' is messy with all sorts of warnings about null pointers, and 'make install' doesn't do a thing.
You don't even need it if you just use pacman to install mono, but you just use pacman -S pkgconfig or pacman -S base-devel if you plan to build things manually.

Midtier Installation Problem - Net config assistant hangs

Hi,
During installation of midtier 9.0.2 on Linux AS, Oracle Net Configuration assistant alone hangs. Retried it many times but the problem is persistant. Could someone please give me directions. My installer is still running.
The system has 1GB RAM and more than 10GB disk space. All my RAM except 6MB are used up.
File sysctl.conf has the following lines:
kernel.shmmin=1
kernel.sem = 100 32000 100 100
kernel.shmmax = 607483648
kernel.shmmni = 100
net.ipv4.ip_local_port_range = 1024 65000
fs.file-max = 65536
At the beginning of installation the system had 1GB+ swap space. Now it has .6GB swap space.
I tried the manual configuraion. Directory schema gets created fine but the net listener port conflicts with the existing listener of infrastructure. Should I assign a different port? Can I perform the configuration after the installation process?
Thanks,
Karthik

It doesn't hang anymore. Just make sure you use fully qualified domain names, for the host (Get a ping reply to make sure). Alternatively, set it up in /etc/hosts.
I recommend using neat for all this. I've tried tu edit the files manually with vi, which didn't work too.
The only problem now is, when I configure the listener, the whole Universal Installer crashes. I re-installed several times, and yet the same thing happens. I even used the recommended JDK, and uninstalled the IBM-Java which was included with Redhat AS 2.1 I can't believe how unstable the whole thing is. All this is really frustrating.

Installation of NET Config hangs on 9i

Hallo everybody,
I tried to install the enterprise edition of the DB on a Windows 2003 machine. When the NET configuration starts it says just "processing" but nothing else happens. Where can I start to search for the error? Thanks a lot!!!

Did you follow all requirements? 2003 Release 2 requires at least patchset 9.2.0.7 and 2003 Release 1 at least patchset 9.2.0.3 .

Dynamic Config Troubles in 2:1 Message Mapping

I am using PI 7.1, and I have a 2:1 mapping that takes two input messages and combines them. The mapping itself is very simple: it takes message A, adds two values from message B and creates message C.
This mapping is in a transformation step in a BPM. Message A has several values stored in its dynamic configuration, but after the transformation step, the dynamic configuration values are no longer available (message C has no DynamicConfiguration object in the SOAP Header).
I tried adding a UDF to the mapping that attempts to read and print one of the dc values contained in message A, but I get a null value. It's as if the dc values that came in with message A are destroyed once the 2:1 mapping begins. How can I pass on these original dc values?
I would appreciate any help you could offer!
Thanks,
David

Hi Abhishek,
Thanks for the response. I don't understand when you say that DC does not work in a BPM. I tried removing the second input message (just making it a 1:1 mapping inside the BPM as a test), and the DC values were read and passed successfully. I also have a mapping in the exception branch in the BPM that reads a value in from DC without problems. It would appear that the problem is the fact that the problem mapping is 2:1 rather than that it's in a BPM, right?
Thanks!
David

Photosmart Plus B209a-m | Wireless Config Trouble

For some reason i can not get my printer to connect to my AP, but i was able to connect to the wireless router. Is there any particular reason why? The only difference between the two access points is the fact that the AP does not have DHCP enabled.. but i dont recall it ever being enabled, and it previously was able to make a connection via the AP.

Check to make sure your AP is in bridge mode (DHCP off) and that it is broadcasting the same SSID and security.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Oracle net config files

hello to everyone,
Which oracle networking configuration files are optional and which are compulsory on the client side, and the same thing, which files are optional or compulsory on the server side?
For example, is sqlnet.ora optional on the server side?
If this makes difference regarding the Oracle version, then it's about 9i and 10g.
Many thnx for any input.
Cheers,
Hiruya

listener.ora is must in server
tnsnames.ora is must in client and in server (if multiple servers are integrated through database by application)
sqlnet.ora is optional in both client and server (is must if domain naming is used)
