TNS Timed out error when connecting from internet

All,
Apologies if I am missing something simple...
I have set up a test 9i database on a Win 2003 Server, and I can connect to it fine from within my LAN. I am trying to connect to the same database from the internet, but am getting a TNS:Operation timed out error.
I believe I have set everything up correctly:
-Port Forwarding port 1521 on my simple Linksys router/firewall
-TNSPing gives me a sub-second OK (from the internet)
-I can get a TNS:listener could not resolve SERVICE_NAME error if I purposely screw up the service name in the tnsnames.ora file (proving, I think, that I can connect to the Listener from the outside internet)
Am I missing something simple? Why can I ping the listener but not get a response when trying to connect to the database (database is working, I can connect from within my LAN)?
Do I need to download and install the latest release for Win Server 2003?
Thanks,
Chris

Thanks for your response, Michael..
Is this something new in 9i? The reason I ask is that I swear that while working on another project last year I was able to set up a development 8i database in my home office and was able to allow my client hit this database from their own location (in Peru, via the internet) using a vb.net app that I had built. The only thing I did on my home router was to forward port 1521.
If my memory is wrong or things have changed since then, then what other ports other than 1521 are used to connect? Security is not really an issue, as I am just trying to set up a test database in order to Q/A an application I'm building.
Thanks in Advance,
Chris

I get a connection timed out error when trying to connect to the itunes store, if I have pending downloads they show up and I can download, also I was able to access my account, yet I can't access other parts of the store, I am in greece on a macbook pro

I am from the states and am in Greece on vacation. I have a good wifi connection yet keep getting a connection timed out error when I try to access the itunes store. It is funny because pending downloads show up in the cue, and they download no problem. I can also open my account. When I try to go the the movies or music section of the stor though it just times out. I tried updating to the latest itunes software and restarting, also I checked all the proxy boxes in the network section of the settings then unchecked them all and restarted and it keeps doing the same thing. Any help would be appreciated.
Thanks

Welcome to AD!
There's been plenty of posts about Norton & the removal tool here. Unfortunately many folks seem to not even know it comes pre-installed on most PCs! Even a trial version, never used or long since expired can cause problems - and not just with iTunes.
Anyone with a Dell, HP, Gateway EEE PC, Asus ..... what Windows PC manufacturer does NOT have this junk software pre-installed?
Almost all of them have made deals with Symantec to pre-install it.
Horrible, horrible software.
Anyway, glad you finally solved your problem.

Experiencing "timed out" error when uploading podcast

I am experiencing a "timed out" error when uploading a podcast to iTunes. Using PC. I've updated iTunes...

- You really need to ask the Basis team to extend the maximum run time for background processes (30 mins is too short).
- You can also try to reduce the run time by setting up BOM Buffering in configuration so if the same BOM is used again and again (in your case of delete and recreate planned order, yes), it will read from memory.
- You should set the planning horizon and use NETPL (net change in planning horizon) in daily run. So that the run will only find the relevant changes in order proposal up to certain days, thus reduce run time.
- You should discuss with your BASIS team about the list of background job in the batch windows. Specify time in such a way that the performance-critical job (i.e., MRP, reschedule sales order, certain customized report, etc.) doesn't run at the same time.
- You can increase the number of parallel processes to issue several jobs to run MRP at the same time.

Connection Timed Out error when I try to access Alert Inbox

Hi experts,
I have not been looking at my alert inbox for a while and I suspect it's very full.
When I tried to open the alert inbox from RWB, I encountered the following error:
<b>500 Connection timed out
Error: -5
Version: 7000
Component: ICM
Date/Time: Mon May 07 11:08:51 2007
Module: icxxthr.c
Line: 2646
Server: ootspdbs02_PI1_01
Error Tag: {-}
Detail: Connection to partner timed out after 60s
</b>
All other functions of the RWB is working fine, including Alert Configurations.
I tried restarting the J2EE instance, but it did not help.
I've checked the SICF services, and they are fine.
I suspect the alert inbox is trying to load a huge amount of data, so it is timing out.
How can I adjust the keep_alive_timeout setting in this case?
When I look into RZ11, I am unable to edit this entry.
Please help.
Thanks.
Ron

Hi Ron,
Follow these steps:
1. Try restarting the JAVA Stack.
2. ST22 check out any Dump.
3. In RWB --> Component Monotring --> check the Cache connectivity test...is all are Green ( Glowing )
Check these SAP Notes 750287,900896,768456
If that doesnt work out, check this SAP Note 840849

TNS timed out error while testing REST service

4.2
11g
Hi There,
We had a new application which was to get and post data using REST API which connects to an internal server. This works fine when we use the Google Chrome Advance REST application through the browser, but get a TNS timed out when trying through Apex
Even a simple sql in the SQL workarea in Apex throws the same error
select utl_http.request( 'http://ourserver.com/api/subscriptions') test
from dual;
ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-12535: TNS:operation timed out
Any idea, what the issue could be? Works fine from the browser though using a REST client
Trying this for the first time.
thanks,
Ryan

Hi Ryan,
During your installation, did you follow the steps to enable Network Services, which is one of the requirements when using web services in APEX. You'll find the necessary information in the installation guide. Also in your utl_http.request call, have you tried specifying a proxy, if one is required? You might also want to take a look at at apex_web_service API, specifically the make_rest_request function, which might be useful if you're looking to invoke a RESTful Service via PL/SQL in your application.

Hilary

4215 Java error: When connecting from IPS event viewer

Hello-
I received a java error when trying to connect to my 4215 with Cisco IPS event viewer. It is as follows:
IOException in open Subscription(): java.security.cert.CertificateExpiredException: NotAfter: Sunday March 29
Is the web server running on 10.x.x.x:443? Please check the communication parameters of the device.
I can set the date on my pc back to last week and all works fine like b4. I have tried updating my java to the latest version and created a new certificate from the IPS.
Any help would greatly be appreciated:
Thanks

Hi,
The issue can be resolved by following the steps as below
1.Login to the sensor.
2.Run the tls generate-key command.
3.Make sure the certificate is generated.
4.Add the device again. It should work now.

Invalid security certificate error when connecting from office for iPad

Hi,
I have Alfresco Community running on my NAS including the SharePoint protocol support and can access it from any desktop Microsoft Office application but when I try to "Add a Place" in any of the Microsoft Office for iPad apps I get the following
error message: "Cannot Connect to Site - The site doesn't have a valid security certificate." followed by "Cannot connect to Server - The server may be unavailable. Check your internet connection and try again".
I have the following configuration
- Qnap NAS with QTS 4.1.3
- JRE 8.6.0
- Tomcat 7.0.50
- Alfresco 5.0.c with Share and SPP installed
- Tomcat, Alfresco and Share configured for SSL on 8443 using a self-signed certificate
- SPP configured for SSL on 7070
- iPad Air 2, iOS 8.2 and latest office apps
- CA and server certificate installed on the desktop computers and the iPad
Share and SPP can be reached on the respective ports and I get the websites as expected. And as mentioned desktop MS office applications can access Alfresco via SPP. But I cannot get it to work with the iPad office apps.
Can anybody help with this, please? I know I am not running SharePoint but I assume the problem with the iPad office app is the same?
Thanks
Peter

1. I can't say if it is sequential or not, I have never seen a message like that myself when doing add-on update checks - but I have seen other messages, like the update server not using a secure HTTPS address after that became a requirement for updates. <br />
Plus, I have never used anything from Conduit - ''the founder of that company has a shady past with different internet companies puling all dorts of "stuff", IMO. And all Conduit add-ons were removed and banned from the official add-ons website a few years ago because of their "antics" and major user uproar at the time - just recently have we seen a few return''.
2. Right-click individual addons and use ''Visit Homepage''' to see if that feature is being used as intended and where it takes you. Or use '''Find Update''' and see if that triggers that message, to discover which extensions are fro Conduit.
3. IMO, you are better off updating each extension one at a time with '''Find Update''', as I mentioned above.

"Shared storage client timed out' error when starting a batch

I'm getting this error on every node in the cluster. What am I doing wrong?

I also administer a managed cluster with 6 machines, and have been using it successfully for almost a year now. But the only encoding that is submitted is directly through Compressor, never via FCP.
With QMaster, it sees a Quickcluster and a managed cluster the same way. While they are set up differently, the principle is the same, QMaster only sees services.
Exporting out of FCP to any cluster has always been slow. If you want to harness the power of distributed encoding, you could export a Quicktime reference file and take that into Compressor to be submitted to the cluster for encoding.
