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.
Regards,
Hilary

Request timed out.- Error while opening a item in Blog

Hi,
   We have a blog in our share point portal which was running properly before few days.
We get Request Timed out error while opening an item in the blog. The list contains about
   3500 items
[HttpException (0x80004005): Request timed out.]
We were able to create a new item but not able to view the item.
When we check the server SQLSERVR.EXE takes more than 90% of the CPU Usage.
Please let me know how to resolve this issue.
Thanks,
Vanitha

Hi,
According to your description, Please check the RAM allocated to your SQL server. MOSS server needs 2GB RAM
to preform well. SQL requires 2GB RAM for optimum performance.
Messages like this are mainly due to lack of RAM Allocation.

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

HI kishore
   This is the problem with ur RFC/data inside table. in webdynpro we r using adaptive RFC model, if RFC is giving output while executing, webdynpro will also do the same. but in VC it will parse each field according to the meta data definition, If it is not matching it will give error.

Hi Babu,
you might try the following on the server where the problem occurred: call transaction SMICM -> Goto Services -> Select the service you are working with ->
Service Change -> increase value for "Max. Processing Time"
In case your application still times out you should see the changed value displayed.
Sometimes just executing the application again 2-4 times might help, because compiling might happen and is taking some time in the system.
With regards to parameters see also SAP Note [824554|https://service.sap.com/sap/support/notes/824554].

Timed Out Error while waiting for response from DB Procedure

Hi Gurus,
We are encountering a problem in our production environment. The system is implemented using AIA foundation pack 2.5 on SOA suite 10.1.3.4.
We have a BPEL process A which calls an ESB Service which inturn calls BPEL Process B. In process B, we have a DB procedure call which waits for a response from
a DB procedure. The procedure doesn't reply on time and Process B remains in waiting state to get the response from DB Procedure wherein Process A errors out by showing as "Timed Out Error".
This issue is intermittent and we have already increased transaction-time outs in transaction-manager.xml to 7200 and ejb-orion-jar.xml to 3600.
When we encountered this problem, we found out that there are too many connections open and when we bounced the server, everything was restored to nornal but as it is a production env. we can't do it over and over again.
We have 2 nodes each having max connections as 100 and min. as 0.
Is there a limit to max no. of connections or can we do something in DB side to ensure that it doesn't happen again ?
Please suggest.
Thanks,
Vikas Manchanda

When we are trying to execute a BI report which returns over 9 lac records, it is taking lot of time to get executed and then its throwing the timed out error.

Is this a problem with the performance of Portal server or its just due to the huge amount of records that are being retrieved?
Thank You.

"timed out" error while transferring music and videos

Hi,
I use iTunes 8.1.0.52. When i connect iPhone and start transferring music or videos it simply throws out "device timed out" error. What do i do? do i have a solution for this problem? My iPhone is updated with latest software 2.2. Any suggestions?

try using a different USB port on your computer. i've seen this before in the forum, and the problem was a bad USB port.
are you plugging in directly to your computer, or through a USB hub? from what i've seen, you can not use a USB hub.

Require help to solve Connection timed out error while reload initial data

Dear Developers,
I have installed SAP NetWeaver and SAP ME SDK 2.0 on my laptop and working from offshore, the SAP ME WIP and ODS database is situated at onsite. The installation is working fine, however, after developing Activity Hooks, at the step where I need to Reload Initial Data for the Site where I want the Activity to be used I get the below error message:
500 Connection timed out
Error: -5
Version: 7011
Component: ICM

Server: <laptop_hostname>_<SID>_00
Error Tag: {-}
Detail: Connection to partner timed out after 600s

How to find out what is causing this error? When I use the hostname of the onsite SAP ME application pointing to the same database, Reload Initial Data works fine. I need to reload initial data from laptop SAP ME application only, beacause the activity hook classes reside on my laptop, before I send the SAPME.sca files for common server build.

Hello,
Please try to increase PROCTIMEOUT ICM parameter for the corresponding server\port. If it does not help, please, check NW default traces for ME errors and share your results with us.

TNS:Operation Timed Out error while trying to invoke BPEL Process from sql

Hi,
I am trying to invoke a BPEL Process from PL/sql code. When i try to invoke the process, I am getting the following error message
ORA-29273 HTTP Request Failed

Any idea what could be wrong..following is the code piece

dbms_output.put_line('after Begin Request' );
utl_http.set_header(http_req, 'Content-Type', 'text/xml') ;
Please advise

you are right the file adapter doesnt invoke any bpel
process, instead it is polling the file from
directory location?If it is polling for new files, shouldn't it create a new instance of the BPEL process automatically the moment it finds a new file? In other words, should a new file trigger an instance of the BPEL process rather than being started from PL/SQL?
Can this file adapter not be invoked as bpel process
in that case?The file adapter is part of a BPEL process. The BPEL process can be invoked from e.g. PL/SQL.
In this case this file adapeter return to an RECEIVE
activity...I think this receive cannot be invoked as
a BPEL process rite?Can you explain what you mean with this?
Also , will all synchronous request return "TIMEOUT"
error, if tried to invoke from pl/sql?Only if the synchronous process instance takes more time to complete (and thus to return) than the value specified for a time-out to occur. If the instance completes in for example 10 ms and the time-out time is specified as 30 seconds, no time-out will occur.

Read timed out error while executing a web service

hi,
i have a remote funtion module which takes around 31 seconds in AAD (developing enviroment) server which has around 4 select queries,the same RFC is taking around 25 mins in AAT (testing environment) due to more data.
Now when i am releasing the respective web service in AAT it is giving read time out error.
Can anybody please tell me if i can increase the Limit of the execution time at ERP end?
or anyother solution?
Edited by: tatavarthi sai lakshmi divya on Mar 28, 2008 11:19 AM

Hi,
if you execute in foreground ( dialog ) then it's gives you the time out error.
check the value of following parameter using tcode RZ11
rdisp/max_wprun_time
if you want to change the value run tcode RZ10 select instance profile and change the value of parameter then save and activate instance profile.
Restart the sap application server.

Error while testing SAML service in PI7.1

Hello all,
I am creating a SAML secured service in PI 7.1
I have used WS adapter in sender communication channel and reciever as RFC adapter to extract data from the system.
I have done the necessary config in sender and receiver agreement and created the wsdl manually.
Now to test that service i have created another component as the client.
The sender is the SOAP channel and in the receiver, WS adapter is used.
With these basic configurations, i have created another wsdl file which invokes my previous service.
When i tested the new wsdl i get an error.
<SAP:Code area="INTERNAL">WS_LOGICAL_PORT</SAP:Code>
<SAP:P1 />
<SAP:P2 />
<SAP:P3 />
<SAP:P4 />

Kindly guide me as to what is to be done for creation of logical port in *NWA as this tool is available for PI7.1 for me.
Regards,
Kevin

Hi Kevin,
What I meant to say is that there are multiple levels of settings required to enable SAML based communication. I wanted to ask you if you have already done those configurations.
See the image given at following URL.
http://help.sap.com/saphelp_nwpi71/helpdata/en/94/695b3ebd564644e10000000a114084/content.htm
As you can see there is multiple parties involved in the overall SAML authentication process.
May be following blog will be helpful.
