Resolved - getting error when connecting to the remote database to the host
Hello
I try to connect to the remote form of database host and get error. Can someone please help.
I've seen a few threads about similar issues, but I am not able to solve this problem.
I use Oracle Apps 12.2.0, Linux 5.1, Oracle Database 11 g Enterprise Edition Release 11.2.0.3.0 - 64 bit, using SQL Developer to connect.
I am able to connect using SQL Developer in distance and using the same credentials in SQL Developer host, but in error
Status: Failure-Test failed: IO Error: Connection reset
The host
I am able to ping remote, but cannot tnsping
The tnsping error-
Use settings files:
C:\app\oracle\product\12.1.0\dbhome_2\NETWORK\ADMIN\sqlnet.ora
EZCONNECT adapter used to resolve the alias
Try to contact (DESCRIPTION = (CONNECT_DATA = (SERVICE_NAME =)) (ADDRESS = (PROTO
(COL = TCP)(HOST=192.168.1.102) (PORT = 1521)))
AMT-12547: TNS: lost contact
Here are more details
I have added the following in the TNSNAMES file. ORA file
SCREW =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.1.102)(Port= 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SCREW)
)
)
I have added the following in the listener
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.1.102)(PORT = 1521))
)
)
Finally - the firewall is disabled in Linux Machine
Can you ping the server IP (or nomhote.nomdomaine) address of the client machine?
What is the error you get when you issue "tnsping SCREWS" of the client machine?
You have added the following entry to your client's tnsnames.ora file?
+++++++++++++++++++++
SCREW =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 192.168.1.102)(Port= 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SCREW)
)
)
+++++++++++++++++++++
Can you reproduce the problem with sqlplus? If so, please see (11.5.10 news: run SQL * Net access for guests (Doc ID 291897.1)).
If the problem with SQL Developer only, please see (SQLDeveloper receives ' java.sql.SQLRecoverableException: IO Error: Connection reset "and ORA - 609 database alert (Doc ID 1483287.1)).
Thank you

When I try to connect to a database as user SYS I get the error as

But it is the registration of the local system where the oracle is installed.
I created the password file and check the content in v$ pwfile_users.
The result is "no selected lines.
then, when I try to grant sysdba to user sys
grant sysdba to sys.
I get the error message like,

I am currently submitting work for P2V conversion from a c# application. I tried to run the application remotely and on-site, but I get this error message (here is the full error):
"< detail > < InvalidArgumentFault xmlns =" urn: Converter ' xsi: type = "vim25:InvalidArgument" xmlns:vim25 = "urn: vim25" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" > < vim25:faultCause > < vim25:fault xsi: type = "ConverterNotSupportedConnection" > < hostName > RSMITH < / hostName > < / vim25:fault > < vim25:localizedMessage > impossible to recognize the type of server or the version when connecting to the host "RSMITH".

RSMITH is the name of the machine with the VCenter Converter Standalone (5.0) and where I wan the VM to go. It's a Windows 7 SP1. I'm under .net 4.0 winform.
Any suggestions? I'm pretty much run the sample out of the box, except for wrapping a winform around it instead of an application console.
Cannot you telnet from your Converter machine on the source IDE oucederomsurlesecondport 9089 machine?

My problem is in "connect to remote server". I manage two sites in Dreamweaver CS6, and they are hosted by the same guy. A site still connects fine, but it stopped connecting. With the second site when I click the button I get a delay then "an ftp error occurred - cannot establish a connection to the host".
However, I can still access the second server in the remote site through an FTP program and support host confirms that my connection works very well from his computer.
I tried to do with the old stuff (1) Site > Manage Sites > export to create an .ste file (2) completely, restart the management of Sites (3) > import the .ste file (4) click on connect to the remote server - But that made no difference
The two sites are hosted by the same company does not mean that they are on the same physical server. Your connection problem may be due to many things.
- Username and password may have changed or been reset.
- Server permissions problems (GoDaddy is known for this).
- IP blocking.
- Server is down.
- etc...
Are you able to connect with an FTP 3rd party like FileZilla client? If this isn't the case, I guess it's a server problem & you will need to contact your host.

Error when connecting with the Remote Console
We get the attached error when you click on a paralytic to vCloud Director. The inner coating IP address is the ip address of the proxy console. Any ideas what might be causing this error? I thought, it might be something with my SSL certificate, but I'm not sure.
1. it's a Windows 7 view Client using IE 9
See the installation and configuration (https://www.vmware.com/support/vcd/doc/rel_notes_vcloud_director_10.html) guide, IE 9 is not supported, and only browsers supported on Windows 7 are Windows and Firefox 3.* 8.*.
2. it takes about 1 minute and 45 seconds, but the error pops up 2 seconds after the Remote Console window opens.
Certainly, that's the problem here. It shouldn't take 1 minute and 45 seconds for the remote console to pop up window, in fact, I would say that it should begin in a few seconds (certainly less than 10 seconds). You are not sure if it's because of IE 9?
4 see attachment log of error messages when trying to access the virtual machine
The error message looks like it tries to connect to my server vCenter. Do the users who are connected to vCloud Director must be able to connect on the server vCenter Server? I thought it would just use the user that configure you when you connect on the vcenter Server.
The console proxy (a component of the cell of vCloud Director) acts as a proxy for users connected to vCloud Director. It is the latter that connects to your vCenter Server server, and that's what you read in the papers.
Try this on any other OS/browser support matrix. In addition, if you can dig why it takes more than 10 seconds for the remote console to the pop-up window, you would have found yourself a solution. If this does not work, contact the Support of VMware.

Hello
I installed Oracle Workflow Builder 2.6.3 recently on my system and after installation, when I'm trying to connect the generator of workflow (using the name of this particular instance database username/password), it throws me the following error message:
220: cannot set NLS_LANGUAGE.
210: oracle error: ORA-01403: no data found
. SQL text: SELECT FROM WF_LANGUAGES WHERE NLS_LANGUAGE: l IN (NLS_LANGUAGE, CODE)
In previous discussions when I searched for the same problem, I found that if
Select the value from v$ nls_parameters
where parameter = "NLS_CHARACTERSET";
Returns the value of other WE8ISO8859P1 then, then that is what I should change my Builder NLS_LANG entry - i.e. AMERICAN_AMERICA. < character set >.
But I don't get where should I change the NLS_LANG, located where... a file any? I'm new to workflow.
Please help me. I tried a lot of things. Any help will be much appreciated.
Thank you
KhadiKhadi,
It is windows server? You can try this
Set NLS_LANG as an operating system environment variable: 1. Select Start - Control Panel - System 2. Select Environment 3. Set NLS_LANG parameter to AMERICAN_AMERICA.UTF8.
Or try this
1. define NLS_LANG Environment Variable on your PC, following below navigation : For Windows Start / Settings / Control Panel / System / Advanced / Environment Variables Define new "System Variable" NLS_LANG and assign it the value AMERICAN_AMERICA.WE8MSWIN1252 Save 2. Bounce the PC 3. Try again database connection from Workflow Builder

Get rid of Web page errors when connecting to the webvpn
It's on an ASA5505
I have a question about the resolution of errors in the web browser when you try to access my vpn ssl interface to download Anyconnect.
I use self-signed certificates.
The webvpn page that will allow users to connect to get the anyconnect client.
For webvpn page I do not use a domain name FULL only her public IP address of the external interface.
For example, I want the clients to connect to https://x.x.x.x/AnyConnectVPN and get the anyconnect client. They will receive the webbrowser error, noting that the certificate is not approved. After that install the cert to the root that goes now, I'm trying to keep from getting the error "The URL that you use to access the site does not match the name in the certificate."
Can I specify the exact page I want vpn users to enter the name of the object CN?
Crypto ca trustpoint Identity_Certificate
LOCAL-CA-SERVER key pair
ID-use ssl-ipsec
no name FQDN
name of the CN=x.x.x.x/AnyConnectVPNobject, OR IT_Dept, O is is BUSINESS of TEST, C = US, St = FL, L = Daytona[email protected] / * /
Thanks for the help.
Triton
The trustpoint you created needs to have the subject name of "CN = x.x.x.x", you do not need to include the "/ AnyConnectVPN".
Hope that helps.
