Unable to connect remote databse via windows XP(using Instant Client)

I have downlaod instant Client and the PATH env variable automatically is set when I install Instant Client. Then I try to connect using the following(from the path C:/XEClient/bin):
sqlplus username/passwd@//host:[port][service name]
I get the following error:
ORA-12170: TNS: Connect timeout occurred
When I ping the host I get reply.
Also I am able to connect to that same database thru perl( so I presume there is no problem with the database not avaiable or port not open etc), where additionally ORACLE_HOME and ORACLE_SID env variable are set to the path in the remote machine. The databse version is Oracle 9.2
Below is the sqlnet.log:
Fatal NI connect error 12170.

Am I missing some set up.
Can anybody help please...I have been trying since last 3 days.
Thanks

Hi Laurenz,
Sorry to say...but it still does not connect(incorporated your suggestions), nor is the trace generated. sqlnet.log looks no different. As about any other oracle clients...I did not have any until yesterday evening when we installed the entire 10g oracle...client and database.
Anyways now too after having installed oracle 10g on D drive, no succes in connecting to remote databse.
Two questions:
1. Is XE client compatible with 10g database? As I am trying to connect to 9.2 version as mentioned in my initial query.
2. When I ping the host I do get reply. BUT when I telnet i.e.
telnet host port
....it says "could not open connection to the host, on port XXX: connect failed"
Does it mean there is a firewall at the remote end which is preventing the successfull connection? But then how do I connect thru' Perl with no extra info...
Any other suggestion please let me know...and also do you suggest I uninstall all oracle clients other than XE...or is there any way out ...having multiple clients?
Another query...hope I can use toad after having set up the XE client?
Thanks in advance...

I am unable to connect to my RackSpace Windows Server via ARD. I have added a computer entering the ip address, username, and password but I can't establish a connection. I am missing a setting or to step that is different in ARD?

I am unable to connect to my RackSpace Windows Server via ARD. I have added a computer entering the ip address, username, and password but I can't establish a connection. I am missing a setting or to step that is different in ARD?

ARD only works with Windows computers if the Windows computer is running VNC server software. Even then it can only control and observe. Do you have this installed?

Please check the following section in
http://docs.oracle.com/cd/E24628_01/install.121/e24089/firewalls.htm#EMADV626
Enabling Oracle Management Service to Access My Oracle Support
Unless online access to the Internet is strictly forbidden in your environment, Oracle Management Service should be enabled to access My Oracle Support. This access is necessary to enable updates and patches to be downloaded, for example.
At minimum, the following URLs should be made available through the firewall:
aru-akam.oracle.com
ccr.oracle.com
login.oracle.com
support.oracle.com
updates.oracle.com
About the dontProxyfor Property
When you configure the Oracle Management Service or a Management Agent to use a proxy server, it is important to understand the purpose of the dontProxyFor property, which identifies specific URL domains for which the proxy will not be used.
For example, suppose the following were true:
You have installed the Oracle Management Service and several Management Agents on hosts that are inside the company firewall. These hosts are in the internal .example.com and .example.us.com domains.
You have installed several additional Management Agents on hosts that are outside the firewall. These hosts are installed in the .example.uk domain.
You have configured Enterprise Manager to automatically check for critical software patches on My Oracle Support.
In this scenario, you want the Oracle Management Service to connect directly to the Management Agents inside the firewall without using the proxy server. On the other hand, you want the Oracle Management Service to use the proxy server to contact the Management Agents outside the firewall, as well as the My Oracle Support site, which resides at the following URL:
http://support.oracle.com
The following properties will prevent the Oracle Management Service from using the proxy server for connections to the Management Agents inside the firewall. Connections to My Oracle Support and to Management Agents outside the firewall will be routed through the proxy server:
proxyHost=proxy42.example.com
proxyHost=80
dontProxyFor=.example.com, .example.us.com
PS: Cygwin has nothing to do with My Oracle Support connection. Cygwin is ONLY required for agent deployment using agent push from OMS.

Hi, i am having a problem in my ipad 2 , it is not showing main screen just showing a black blank screen in which downloading icon is only shwn which is continously and when i connect to itunes via windows 7 it showing this error (0xE8000065) can any one

hi, i am having a problem in my ipad 2 , it is not showing main screen just showing a black blank screen in which downloading icon is only shwn which is continously and when i connect to itunes via windows 7 it showing this error (0xE8000065) can any one

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

HT4623 After ios update on my ipad mini i am unable to connect to internet via cellular connection

i Have update ios 7.0.2 on my ipad mini. But after update of ios 7.0.2 i am unable to connect to internet via cellulau connection. Cellular connection appears on my screen but i get error as "Could not activate cellular data network you are not subscribed to a cellular data service". Cellular connection was working prior to ios 7.0.2 update. Please help.

GOT MINE FIXED -
THE 7.0.3 update reported my iPhone as LOST or STOLEN to Verizon.
They suspended my iPhone service immediately (as I would expect them to) and THAT is why I couldn't get on.
Called Verizon wireless - they restored me in 30 seconds - EVERYTHING WORKS AGAIN.
They said "we've been doing this ALL MORNING."
Hope this works for others, too!
You blow bright orange chunks, Microsoft, er, I mean, Apple.

#1 Check the level of WEP. Two examples: 64 Bit, 128 Bit.
#2 And check to be sure, if you use a WEP password of Hex or Ascii.

OCIEnvCreate fails with -1 using Instant Client 10.2.0.1 on Windows XP

I have a working application (using the full Oracle install) and I'm trying to see if I can get it to work using the instant client. I installed the client, changed my path and rebooted. According to the instant client how to install - it should just work but then if everything worked like it was documented then lots of support folks wouldn't have jobs. The only parameter I'm setting is the OCI_THREADED flag. The database is on a different server - but that shouldn't matter I'm not getting that far. I am logged into an administrator account on the client box - so I'm not sure what else could be wrong. Also if anyone knows why we always seam to need administrator accounts that would be a great piece of info too.

It should work if you follow the instructions on the instant client page on OTN:
http://www.oracle.com/technology/tech/oci/instantclient/index.html
Are you able to connect to SQL Plus after setting up instant client ?

Unable to Connect to my organization's EAS using MS Mail app since upgrade to Windows 8.1 -- certificate error

Last November, my ASUS laptop forced me to update to Windows 8.1. Since then, I cannot connect to my organization's mobile EAS using the Mail/Calendar/People app. The Mail app says "We could not connect to .... because of problems with its
digital certificates. Contact your system administrator for info." I also tried to delete the account and recreate it. At the account info screen, it gave a related error message, stating "To connect to this account, you need a
valid certificate on the PC. Contact your system administrator for more info."
In trying to recreate the account, I note that the 8.1 Mail app appears to have combined all EAS connections -- I seem to recall different options for connecting previously, including one that was more specific to mobile EAS connections. My organization
only supports connection to mobile devices, and I continue to be able to connect via Windows phone, Android (iOS devices also supported).
I have done some digging and see that in my Windows Certificate Manager, there is a Personal Certificate with an error message. It's a "Token Signing Public Key" for "Client Authentication" using an RSA Public Key, but under the Certification
Path tab, the status states "The issuer of the certificate could not be found." I suspect this is the certificate that my organization's server is sending but is no longer being recognized by Windows 8.1.
My organization has been unwilling to support me on this. They point to the fact that all other devices work, my connection worked with Windows 8.0, and they don't have enough users that connect via Windows 8.1 laptops/tablets to troubleshoot on their
end. They also don't want to change setting that then cause other users to lose connectivity on the more commonly used mobile devices.
So, to trouble shoot myself, I have looked up posts on related issues and I have done all of the following to no avail:
- Make sure my Windows is up to date, including that latest Certificate/Credential update;
- Uninstalled the Mail/Calender/People App, restarted, and reinstalled it;
- Had MS Online support try to trouble shoot. They created a test account and tried to connect using that to no avail.
Notably, I have two Windows 8.1 machines -- my wife and I got matching ASUS laptops that both upgraded to 8.1 from 8.0 -- and I am unable to connect to my organization's mobile EAS using either machine.
To me, this is clearly a Windows 8.1 issue. The Mail/Calendar/People app should interface with mobile EAS exactly the same way that other mobile OSes do. Apparently this was the case with Windows 8.0, but no longer.
The last thing I'll add is that my organization requires password and remote wiping when connecting to the mobile EAS. But, this wasn't an issue when I had Windows 8.0 -- it connected fine and mandated password and remote wipe features.
NOTE: I originally posted this question on the Windows 8.1 Tehchnet forum and was told by an MS Engineer Soumya Sunda Debroy to repost in this forum.
PLEASE ADVISE. YOUR HELP IS APPRECIATED.

Unable to connect to Internet via Airport Express - 'cannot contact server'

I'm unable to connect to the internet via my Airport Express. I'm using OS 10.3.9, and had the same setup with no problems at a previous address, but with a different modem from the same ISP.
My AE is connected - the light is green - and my mac is connected to the network in Internet Connect. But when I open Safari I get an 'unable to contact server' message.
I've tried rebooting everything (modem, AE, Mac), and leaving modem/AE off for several minutes. Also reset the AE, but to no avail.
The connection works fine via Ethernet cable.
Any ideas?

Thanks, I checked out that advice doc (106798), but could not connect to the address (http://17.149.160.49) which is given to test if it's a DNS issue. My ISP says I shouldn't need DNS settings.
The service is PPPoE, and I went into Airport Admin Utility to check if the Airport was configured for this. Under Configure/Internet, I found it was set to 'Ethernet', so changed it to PPPoE. Then when I restarted I got connection status in the bar (and good Airport signal), but status flipped between 'looking for PPPoE host' and 'negotiating PPPoE host', sometimes sticking on one or the other each time I tried rebooting all gear.
Any other ideas?

I think I got a resolution of the problem. I had to do the following steps to get the installer successfully connect to my repository schemas in Windows 7.
steps:
1- Change my home router setting to reserve specifc IP adresses to all MAC addresses on my home network. If your router does not have this "reserve" feature , you need to disable DHCP and assign static IP to all machines in the lome LAN.
1- Disable firewall in the Linux guest where I am installing OBIEE.
2- Change Windows firewall rule to allow all port and all protocol connection from range of IP in the home LAN. If you have time you may be able to trim this setting to allow specifc ports and IPs.
I also installed oracle instant client and sqlplus in the Linux guest to help me troublesoot the connection problem. It does not require a permanent oracle home to be set. So it won't interfere on obiee home etc.
Thanks all for your help.

Hi Hector M.Devarie,
Would you please check if can ping the server successfully by using server name and IP address? Please temporarily
disable firewall and then connect to server again. And monitor the result.
You descript “I'm able to download the connector software”. Would you please let me know the complete error
message when can’t download. Or provide a screenshot, it will help me to understand this issue clearly.
By the way, please check if IIS run as normal in the server.
Hope this helps.
Best regards,
Justin Gu

I am trying to connect to the server, but the connector method shows the message "unable to connect to server"
While debugging i found the iResult to be -1 which makes the socket INVALID_SOCKET
Kindly help resolve this

Hi askatral,
connect function can return invalid_socket for many reasons, what does the function WSAGetLastError return?
There are some Variables that I cannot find how it is declared, like "socket_" and "ptr". So I cannot check if there is anything wrong in your code.
Maybe this sample in the document of connect function is helpful for this issue:
