Notification callback via proxy failed

I access database through a proxy, because my PC and database PC stay in different network, we can't see each other directly.
I tried to write a 'notification call back' application through Subscription class, it failed to get notified. Could the network condition be the problem?
p.s. I wrote the code according to a post which is claimed by the owner running successfully.

thanks A Non. I'm using a client side function.code as below:
m_sub->setSubscriptionNamespace(Subscription::NS_AQ);
m_sub->setProtocol(Subscription::PROTO_CBK);
m_sub->setPayload(*m_bytes);
m_sub->setCallbackContext((void *)this);
m_sub->setSubscriptionName(queue_name);
m_sub->setPresentation(Subscription::PRES_DEFAULT);
m_sub->setNotifyCallback(&notifyClient::eventHandler);
m_env->enableSubscription(*m_sub);
m_subs.push_back(*m_sub);
m_con->registerSubscriptions(m_subs);
notifyClient is a class, eventHandler is a static member function of notifyClient. All the objects used are members of the class.

java.net.ProtocolException: unrecognized response from proxy: 'HTTP/1.1 403 ForbiddenThis looks like that the proxy is expecting an username from soa server for authentication and you have not configured soa server to send the username/password to authenticate at the proxy server. I am not sure if soa server has a way to specify username/password for proxy authentication, but a workaround we used to do in an earlier version of OSB ( ALSB 2.5, where there was no provision to specify proxy authentication crdentials) was to add the URL's you want to access via proxy, to the 'proxy-free-list' of the proxy server. A proxy wont prompt for username/password for accessing an URL which is in its 'proxy-free-list'.

Hi Chaitanya,
Looks like the ABAP code failed during a call to DB. You would have to sit with ABAPer fot this to debug and see where exactly the exception is being raised. Set a debug point in Proxy code and debug the message. You can use sproxy to test this.

XI to BI via Proxy

I am pulling an .xml from a ready folder into XI then sending it to BI via proxy. Once it is in the BI box it shows that the message is successful however i do not receive any data in the PSA. Is there some kind of config on the BI side that has to be in place first? The data sources are there but it seems like something is missing.

HI
Check with the BI person Delta queue in BI can have issue while pushing the data from Proxy.
for your understanding you can refer this

Send a notification to the proxy when he is removed as proxy

We have a requirement to send a notification to the proxy when he is removed as proxy.
There is one out of box notification to the proxy when assigned. But could not figure out an option to send a notification when proxy is removed.
Is there a way?
Thnx
Sid
Edited by: Sidharath on Jun 4, 2012 2:23 PM

yes, there is a OOTB system property called XL.ProxyNotificationTemplate to tell user that he is a proxy. But as far as I know there is no notification to 'proxy removed' .
1-You can create a system property and add SQL's into it. Please check this link I replied before: Re: Exception while setting security question
2-You can create a trigger into database (proxy table=PXD) that start some procedures(including e-mail notification) if proxy user is removed.
I hope this helps.

Issue with AQ notification callback.

Hi,
I'm using OCCI API to subscribe for event notification.
I was able to open subscription and the callback is triggered when the messages are enqueued from DB.
I'm having issues with extracting the data in the callback.
From the oracle doc, I see that only RAW payload is supported if the queue is non-persistent. Different payloads are supported if the queue is persistent and that the user is supposed to explicitly dequeue messages since the messages are not provided as part of NotifyResult argument of the callback.
My question is how do I dequeue messages when the callback is triggered.
I tried to use the consumer with in the callback as below:
Consumer consumer(_connection);
consumer.setConsumerName("fbe_ac1_usr");
consumer.setDequeueMode(oracle::occi::aq::Consumer::DEQ_REMOVE);
consumer.setQueueName("xrfdbo.fbe_ac1_queue");
Message mes = consumer.receive(Message::OBJECT, "CONSOLIDATED_UPDT_MSG_T", "XRFDBO");
PObject* obj = mes.getObject();
I'm getting the exception "21301ORA-21301: not initialized in object mode"
I believe this is due to Environment being created in EVENTS mode to register for subscription.
If I change the mode to OBJECT when I create Environment, I'm getting exception "ORA-01010: invalid OCI operation" while registering for subscription.
Is there any other way to dequeue DB type messages when callback is triggered ?
In order to create a consumer within the callback, I changed my Connection object pointer as static. Is this the right way ?
Thanks

Environment modes are cumulative. You need to define both object and events mode at the same time, which you can do with a bitwise OR of EVENTS and OBJECT.
You are spot on about non-persistent queues. They are deprecated (and slightly buggy, you get the raw payload as an XML document if you dereference the payload pointer in the notification callback function, but I find things go missing, like timestamps for instance), it's replaced by a new kind of persistent queue that behaves similarly to NP queues. I forget the marketing name now, let me go look it up and update the thread.
EDIT: buffered queues.
http://docs.oracle.com/cd/B19306_01/server.102/b14257/aq_intro.htm#sthref76
It's a persistent queuing but the messages live in shared memory until the streams_pool_size is reached. I could be wrong, but I think Oracle built on this to provide continuous query notification.

Java URLConnection via proxy

Hi all, I need help!
i have web server in our network, but i need get pages ONLY via proxy, not directly!
I try next(and others):
class SimpleAuthenticator extends Authenticator {
private String username, password;
public SimpleAuthenticator(String username, String password) {
this.username = username;
this.password = password;
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(
username, password.toCharArray());
Authenticator.setDefault(new SimpleAuthenticator(
"username","WRONG_PASSWORD"));
System.getProperties().put("proxySet", "true");
System.getProperties().put("proxyHost", "proxy");
System.getProperties().put("proxyPort", "3148");
URL url = new URL(urlstr);
URLConnection conn = url.openConnection();
BufferedReader in = new BufferedReader(
new InputStreamReader(
conn.getInputStream(), "windows-1251"));
but everytime i get url correctly(but in this example i should get proxy exception)! :(
I must be sure that my connection via proxy!!!!
How i can do it?

I changed my code on:
class SimpleAuthenticator extends Authenticator {
private String username, password;
public SimpleAuthenticator(String username, String password) {
this.username = username;
this.password = password;
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(
username, password.toCharArray());
Authenticator.setDefault(new SimpleAuthenticator(
"username","WRONG_PASSWORD"));
System.getProperties().put("http.proxyHost", "proxy");
System.getProperties().put("http.proxyPort", "3148");
URL url = new URL(urlstr);
URLConnection conn = url.openConnection();
BufferedReader in = new BufferedReader(
new InputStreamReader(
conn.getInputStream(), "windows-1251"));
and nothings happened, i get page correctly(no 401 Unauthorized response) :(

Kerberos via Bonjour fails (Mac OSX Server 10.6.2)

we setup an test-environment with server and clients (all running 10.6.2).
we had added also "non apple" server-machines (debian linux, windows) successfully.
the desired setup is to have SSO via Kerberos and managing users in the open directoy on a mac-server. A sync with "mobile accounts", timemachine etc. works.
anyway I am stucked with the Bonjour advertisements under "shares" in Finder. It seems that Bonjour does not advertise the "FQDN" of the mac-server but only the hostname. So connecting to the server in Finder via browsing fails although a Kerberos ticket availiable.
Using cmd+K and connect to "afp://server.domain.com" (so using the FQDN) works, the connection is established via the Kerberos ticket.
I had a similar problem when integrating the linux boxes. Here "Avahi" is used to broadcast the FQDN so the connection can be done (aka the Kerberos ticket is used).
How can I have the same thing in Bonjour, mostly just changing the advertised hostname for an entry ?

Reco,
In thread http://discussions.apple.com/thread.jspa?messageID=647522&#647522 , Nemesis talks about "Inherit permissions from parent" requiring restarting the server. I don't know if you have tried that.
You have probably seen this in your searches, http://kb2.adobe.com/cps/322/322391.html, where Adobe states,
"If you use Photoshop CS without Adobe Creative Suite or Photoshop 7 or earlier, Adobe Technical Support strongly recommends working in Photoshop directly on the local hard disk to prevent data loss. Save files to your hard disk first and then transfer them to the network or removable drive in the Finder or in the Windows Explorer. To retrieve files, copy them in the Finder or in the Windows Explorer from the network or removable drive to your hard disk then open the files in Photoshop. This will also avoid problems that may come from differing network system setups (for example, Windows NT Server, Netware, or AppleTalk) and removable media device drivers not being completely compatible with the operating system or Photoshop."
If you are just supporting Apple boxes what about this as a work-around?
1) Attach an action to a local folder. That action would copy any aded file to a network folder of your liking.
2) Set up an Applescript to copy the file from the network to the local directory set up in step 1. You could go further and even have the Applescript open the file in the appropriate application.
Additionally, if you are supporting just 10.6 clients, you could set up a File Service using Automator so that the client could just control-click on the network file and trigger the Applescript.
I imagine a similar type work-around could be setup for Windows boxes also.

Time Capsule as Router via Proxy

Hi all,
Thank you in advance. I recently moved to a new apartment complex that connects each room via proxy.
There is an ethernet cable in each room. IT takes our computers Ethernet ID, puts it in his machine, and then we put the proxy server and port in Firefox to connect to the internet.
I want to use TC as a router in the apartment. I set it up correctly (green light), and I gave the TC Ethernet ID to the IT department. But in Airport Utility I cannot find where I should enter the proxy server for TC.
So, while I can connect to Time Capsule and can backup with Time Machine, I cannot connect to the internet because the proxy server does not go through.
I hope this was clear. Please let me know what else I should tell you.
Thanks,

Hi,
I'm facing exactly the same problem. Could you please tell me where you entered the proxy server for the Time Capsule ?
Thanks,

Consuming utl_dbws webservice via proxy gives error (sometimes)

Hi all,
We provide a webservice for our clients, and some of them have reported they have issues calling a specific operation. Only clients who connect through a proxy have this problem. Others can call the service without issues.
When I browse to the wsdl (both from my local machine, and via an RDP-session to our customer's network) I get result, so I know the service itself works and that we can connect to it.
The service has 4 operations, each returning an xmltype.
When I call the first operation (from my machine aswell as the customer's machine), I get the correct result.
When I call the second operation from my machine, I get the expected result, but hen I call it from the customer's machine however (which connects via a proxy), the service errors out with following message:

I'm actually considering rewriting my code to use utl_http (as I've done before) but that would be my last resort.
Anyone have any ideas as to why this sometimes fails?
TIA!

Some extra info: the webservice is hosted in an OC4J container on a 10g application server (judging from the Help pages I'm guessing the full version number is 10.1.3).
I can access the Enterprise Manager and I found a Logs section in there.
The "Last modified" column for the webservices' Audit and Trace logs show June 30, with a size of 0B (even though I tried again a couple of times today).
The diagnostic logs (found in the Components -> OC4J -> webservices (this is the container's name) -> Diagnostic Logs section) show a couple of warnings in there on July 16, at about the same time I tried executing the webservice, with a Message Text saying "Unable to determine operation id from SOAP Message.", but there's no log for today, so not really sure if that's the correct file.
The server.log (Components -> OC4J -> webservices -> server.log) keeps updating, but shows only "oracle.ons.Notification@1b4fd6a" messages, so that's probably not it either.
I can also see the response/load graph updating as I execute the webservice, so I'm pretty sure connectivity is not the issue here.
Any advice as to which log file I'm looking for?
