for hours now I am struggling with this. I am complete newbie to Oracle DB 11g and its really to complicated for me :).
I have installed it and it's working properly. With SQL Developer I can connect on localhost, but its not working on other machines.
I HAVE TO USE NORMAL HOST - user/password access.
I am trying to use EM for editing, since i don't want to mess up. I have set it up to work remotely. Now... I was trying to configure listener to listen on my (even) internal network IP. But its not working. I have heard about editing TNSNAMES.ORA but I can't find them in EM.
Any help please? What should I do, I am completely confused and all the time I get
The Network Adapter could not establish the connection
In the listner.ora file under your network/admin folder, change
HOST = localhost to HOST = ComputerName.
It worked for me.
Use the netca tool to configure your listener.ora and tnsnames.ora files.
Make sure listener is up. Use tnsping tool to test connectivity.
Make sure to bounce listener after you make any changes to listener.ora. Go to windows services to restart listener.
Finally found easier solution.
Use Oracle Net Manager and add Listener on IP (of the machine) on the same port.
Restart, and it works.
Its the same as Venu's solution, but easier.

Hey this is my first question on here, so go easy.
I set up a Nextcloud server on my homelab in an ubuntu server 20.04 vm using the snap install. I have a seperate vm running nginx as a reverse proxy to my Nextcloud instance. Everything works flawlessly as intended, except that when I try and install apps on Nextcloud, I get a curl error #7. I've tried using my lan ip through the web ui, my public domain name through the web ui, and the commandline using the nextcloud.occ app:install command. I always get the same error. I tried to find the appropriate log file to get more information but looking in /var/snap/nextcloud/current/log/ I couldn't find any relevant info in any of the logs. Running php -m comes up with php not installed, I guess because php is installed via the Nextcloud snap? Obviously php is installed somewhere because Nextcloud is running, but I don't know how to look and see what modules are enabled, or how to install new ones using the snap. Any help on what to do is much appreciated!

Update: I fixed it. I think I had improperly configured my firewall, and turning it off (in proxmox)/making some changes to my /etc/netplan/*.yaml file to properly configure the static IP fixed it. GL
Another reason can be a wrongliy configured network. I forgot to set the gateway/proxy for IPv4, so github.com was unreachable. Most other services I use seem to resolve IPv6 first, so I did not have any other problems besides updating nextcloud apps.
I downloaded the Teradata express VM today. But I don't use vmware... i use virtual box instead. I created a new VM and added all the vmdk disk files to virtual box.
but it is throwing error could not find /dev/disk/by-label/ROOT-BE1. Want me to fall back to /dev/disk/by-path/pci-0000:00
does anyone know how to boot the vm image with virtual box?
I have the same problem, with the same message. The same mistake.
The solution is simple. Just change the Storage Controler to SCSI. After this, restart the VM and it will start normally, but in command line.
I try, but i can't run the startx command...
Try adding IDE controller and then add the disk as existing hard disk device. This should let you boot into the OS.
I saw this exact error when trying to load the VM in KVM. What seemed to fix it was selecting 'single user mode' in the grub menu. After booting like this once, selecting the default grub option subsequently allowed the VM to boot further than this error.
Note that I haven't been able to successfully bring up the actual database yet - the service doesn't start automatically, and when I start it manually, it reboots the VM, bringing me back to the same state as before. Maybe you'll have more luck with VirtualBox?
I have a question hopefully someone could explain it to me. I have an Oracle 11g installed properly on the server. From a workstation, I have installed the oracle client which tnsname.ora pointed to the Oracle database. I can ping to the server where oracle db was installed. I can sqlplus connect to the database and I can even connect to the database programmatically using C#. However, I can not tnsping to it. I got error Message 3511 not found when trying to do so. So my question is: in what scenario tnsping is used and how do I make tnsping works? In other word, if my tnsping does not work but I still can connect to the database programmatically using C#, what are the concerns that I should be worrying about? I am new to Oracle.. Thanks!
I have tried to do the following actions without success although they are the most popular answers to similar scenario similar to mine.
1) Set Oracle_Sid to my oracle sid
2) Set Oracle_Home to my oracle home directory
What I did to solve the issue:
1) Uninstall oracle client
2) Reinstall the oracle client with the newest version 11.2.xx.
I believe, re-installing the oracle client of earlier version would just work as well.
However, since I have to re-install the client, I might want to get the newest version.
The cause is probably improper installation at the first time as we have an disk image of pre-installed application to automatically prep a new computer.
Not able tnsping does not seem to impede with other Oracle operations (at least not that I know of).
If someone knows what is the limitation of not able to tnsping but can sqlplus connect, ping... , I would appreciate if you could share.
Either your $Oracle_Home value is not set or your default sid is not set in $ORACLE_SID
Try this :
set ORACLE_SID=mysid
export ORACLE_SID
tnsping mysid
and see what it comes back with.
I am having difficulty connecting to a existing Informix database. I am attempting to mimic the configuration that is present on another machine which currently works. By the way, that other machine is on the same network and it is accessing the DB through a tunnel, so I am pretty sure the issue isn't related to the network configuration.
Regardless, here are the steps that I took to try and make the connection
Downloaded clientsdk.3.50.TC9DE and installed this. The working machine uses 3.50.TC2DE, but I couldn't find the installer for that version. (Note that at first I tried using 3.50TC9, not sure if that makes a difference)
Matched the ODBC config in the new machine to the working machine
The working machine has a host name in the Host Name field. I assume this was allowed because the host was set to an IP in the hosts file. Regardless, I am using the IP.
Also I am using C:\Windows\SysWOW64\odbcad32.exe to create the DSN
Made sure that the INFORMIXDIR and PATH directory were correct. as per http://www.dbforums.com/informix/694408-odbc-test-connection-not-successful.html#post2633932 I don't think the locales are the issue because they aren't set in the working machine's Setnet32. Also, I made sure that the locales matched in the ODBC environment settings.
Also, since my INFORMIXDIR is in C:\Program Files (x86)\IBM\Informix\Client-SDK\bin I tried replacing Program Files (x86) with PROGRAM~2 and Client-SDK with CLIENT~1 to no avail.
Tried setting INFORMIXDIR directly in my system environment variables (outside of Setnet32)
Set DBPATH to match the working system in both the user and system environment variables.
Set INFORMIXSERVER to the server in both Setnet and the system environment variables.
Completely lowered the firewall on my machine.
I can ping and telnet into the server.
I have also tried..
Tried this on Windows XP
Tested the ILogin demo. The result was a popup that stated Customer Records Found in the title bar with an empty text area field.
Reinstalled into C:\informix instead of C:\Program Files(x86)...
Rebooted after various steps.
At this point I am at a loss. Has anyone run into this? The only other things I can think of is that I am using Win7 64-bit (with 32 bit drivers) and that the driver is 9DE not 2DE.
Alright so half of the battle is over. I was able to get a "Test connection was successful" on my Win7 machine. We had a copy of the 2.90.TC6 driver available in our file server from way back. I installed it and it worked. So my guess is that the database I am working with isn't compatible with 3.50.TC9DE.
I guess my next course of action is to try and find an installer for 3.50.TC2DE so that I can match the production system.
I'm trying to setup automated GUI tests in ESXi Virtual Machines using TestComplete. The problem, as I understand it, is that when no remote desktop connection is made to the ESXi virtual machine, then it is impossible for TestComplete to perform screen captures and therefore automate the GUI testing. As far as I understand it, this is due to the fact that Windows does not generate any user interface when nobody is viewing it.
I'm sure other have experienced this problem. How did you solve it ? Are you using a third party computer which automatically launch remote desktop connections prior to running the tests ?
Would it be possible to launch a remote desktop from a head-less virtual machine to another to fake somebody viewing ?
Any other smarter solutions I haven't thought about ?
You should be able to log in to Windows on the VM's console using the vSphere client, then close vSphere, and Windows will still believe the user is viewing the console. Simple as that. :)
So there shouldn't be a need to involve remote desktop in the mix.
As long as your tests then run as that logged-in Windows user, you should be fine.
This technique has always worked like a charm for me with certain Watir, Selenium, and MS UI Automation tests that depend on having an interactive desktop.
If you need to reboot the VM automatically before/during the test, instead of logging in manually in the vSphere client, you can make Windows log in as an arbitrary user automatically - check the "control userpasswords2" command, or you can use the Sysinternals app "Autologin":
http://technet.microsoft.com/en-us/sysinternals/bb963905
Only catch with this technique is that you need to be able to launch your tests while not viewing the console on the VM, but it sounds like you've already taken care of that?
If you need a solution for launching your tests remotely, I highly recommend using Jenkins or Hudson to kick off tests/collect results from the VM. Jenkins has changed my life in this regard.
You may consider using the Network Suites functionality of TestComplete:
http://smartbear.com/support/viewarticle/16849/
It can open Remote Desktop connections on its own, control tests on remote PCs, and pull the logs back to the "master" project. This feature is designed to be used for distributed tests, and looks like it's just what you need.
As for opening RDP to a head-less VM, it should not be a problem - it's up to Windows to "think" about this. You just open RDP and it works even if there is no monitor attached to the remote PC/VM.
I hope this helps,
Alex
You can always use VNC with checking the option "Do nothing" when disconnecting viewer. This way you'll trick windows to generate the image.
