HTTP Queue

Hi All,
I have Http to JDBC scenario in which I need to send the messages EOIO.
For this I need a queue.In Http client I set the QoS : EOIO .But I need to give a 'queueid' to make use it.
Plz any one knows how to create,Register and Acitvate the Queues.
Thanks
Praveen Kumar

I updated the HTTP client on the sender side, added the parameter queueid to the URL string and assign it with some name.
Queue has created with the respective name assigned to the queueid.The corresponding XML schema will be passed through the same queue.
But am getting the following error while sending through HTTP client:
Result:
<SAP:Error><SAP:Category>XIServer</SAP:Category><SAP:Code>INTERNAL.ATTRIBUTE_INITIAL</SAP:Code><SAP:P1>QUEUE_NAME</SAP:P1><SAP:Stack>Attribute QUEUE_NAME is initial</SAP:Stack></SAP:Error>
Any clue on this error?
Thanks

HTTP Queue for EOIO

Hi All:
Few days back I raise a request (forum) regarding HTTP queue creation for QoS = EOIO. I spent much time on SDN just to find any hint how to create a Queue from HTTP url(Sender).
Error I was getting "INTERNAL.ATTRIBUTE_INITIAL" for "QUEUE_NAME".
At last I come to know that it was a bugg in XI and due to which queue was not created. Please
refer a SAP Note: 1073448(it is created just 4 days back) - Plain HTTP adapter: Queue ID is not accepted.
This is just to share little information from my side.
Thanks
Farooq.

This issue has ben solved. SA Provided a patch for NetWeaver 2004s SP11....

HTTP Sender with EOIO leads to HTTP Response 500

Hello everybody,
since we are using SP12 we have problems with the HTTP sender when using EOIO. If I use the two parameters ....qos=EOIO&queueid=myQueue... I got a HTTP Reponse Code 500: Internal Server Error in the sender system (for the test I use a Java Program). When I use the qos EO (without a queue ID) it works.
Does anybody now this problem?
Regards,
Thomas

Have u seen this
HTTP Queue for EOIO
Also have a look here SAP Notes 804124, 807000

High number of threads and high CPU usage on a single instance

Without any apparent reason, in some moments of day the website reports an increment of the HTTP Queue Length from an average of 10/20 queued requests to 100/200 and more.
In that period of time the Average Response Time increases but the number of the requests on the website don't. Even increasing the instances it doesn't help to resolve the problem (maybe it just reduced it).
It seems that the problem is not related to the traffic on the site. This issue happens either when the traffic is high or low.
The autoscaling works well, we don't have peak of traffic but always a slow increasing of requests and the CPU is always below the 50% (memory too). The issue is resolved by the swap of the site and sometimes it's resolve by itself after a while.
What I discovered when the issue happens, is that there's an instance (just an instance only), that has an high number of threads and CPU usage on the W3WP.exe process and these values are above the mean than the other instances. Eg, instances are around
50/60 threads and 10/20% of CPU, the instance with the problem has 200 threads and 50/60% of CPU. If I kill the W3WP process on that instance the issue is resolved.
I monitored the HTTP requests, I tried the website extension "Diagnostics as service" but I can't discover anything that can help me to understand the problem. Of course, there are many requests that go in timeout but it is a consequences of a
unresponsive instance.
On the web hosting plan there are only two sites: the production site and its staging which is used for update of the production only and it's always sleeping. Plus, no webjobs are running on this site.
What can I do to gather useful information that can help me to understand the reason of this problem?
Thank you!

"Does the instance with the high counts receive more traffic than the other instances? Is it possible that the load balancer not
working the way it should be?"
How can I get that information? I can't see metrics for a specific instance
"Does it always happen to the first instance?"
I will check it better, but in the order given by the Processes panel it's the second instance which has the issue. The scaling is at 2 instances for the most part of the time (it's the minimum).
Maybe one time it was the 3th instance but I'm not sure, I'll give it more attention.
" How long do these moment last?"
The time can be 10 to 30 minutes, but I fix it as soon as I see the problem. It's not the down-scaling to resolve it because in these situations the CPU as well is high so the scaling holds or increases the number of instances.
"- How often do these moments occurs?"
It occurs quite often, 2/4 times a week.

Questions on CBWFQ

Hi every body
CBWFQ uses both custom based ( with a little enhancement i.e we used percentage of interface bandwidth rather than byte counts) and weighted fair queuing using class map and policy maps
Here is my confusion.
In Custom based queuing we have queues with bytes counts and scheduler uses round robin method to empty them, for example :
http traffic assigns to q1 byte count 2000
ftp traffic assigns to 2 byte count 200
q1 will be serviced first until byte count reaches zero then scheduler moves to q2 and services it until q 2 byte count reaches zero.
Here we have control as to which traffic goes toq 1 and thereby we can control which traffic get serviced first before others.
Now if we compare this with CBWFQ,specifically custom-based portion of CBWQ we do not have this control.
for example.
Class HTTP
match http
Class FTP
match ftp
policy-map NEE
class Http
bandwidth 10
class-map Ftp
bandwidth 20
int s0/0
service-policy Nee output
Above , we are saying http traffic will get upto 10 percent bandwidth of s0/0 ,ftp will get 20 percent.
But which queue will be served first? http queue? or ftp? queue? ( because my understanding is in CBWFQ, we still follow round robin algorithm to empty our queues, that means the q1 will be service first than q2. When we use CBWFQ we do not know which queue will be mapped to http or ftp in my example)
thanks.
have a great weekend

Yea, the policy says that, but that's only true if CBWFQ is active, all the classes are active, all the class allocations add to 100%, and all the classes are trying to exceed their allocations.
But which queue will be served first? http queue? or ftp? queue? ( because my understanding is in CBWFQ, we still follow round robin algorithm to empty our queues, that means the q1 will be service first than q2. When we use CBWFQ we do not know which queue will be mapped to http or ftp in my example)
Actually, CBWFQ for non-LLQs is very similar to custom-queuing. Queues are serviced to try to maintain the ratios between them. In your example, FTP will be dequeued such that it transmits twice as much data as HTTP; because of the 20 and 10 percentages or 2:1 ratio between the two classes.
If you wanted to know, from an "even start", which class would transmit first, I don't know, and as it isn't documented, I wouldn't count on it always being the same between platforms and/or IOS versions.
As it's packets that are transmitted, during short time intevals, if there a large size difference between the packet sizes for HTTP vs. FTP, the 2:1 ratio won't be exact, but it should average out over a longer time interval.

May i know how can i consume this service with transport level security. I got the certificate and private key from Amazon.

The error message says "java.lang.NoClassDefFoundError: oracle/j2ee/ws/common/jaxws/ServiceDelegateImpl" which means that you don't have this class in the classpath. If you're using JDev 11g you can search for this class to find out which library has it:
1. Double click your project. It can be any project
2. Select "Libraries and Classpath"
3. Click on the "Add Library..." button
4. Enter the class you're looking for in the search field. JDev will show which Libraries have this class.
You can find the related jar file that has this class on {JDEV_HOME}\jdeveloper\modules\oracle.webservices_11.1.1\wsclient.jar .
AFAIK, there's no direct Web Service access to Human Task Flow. You need to go through the client API which is responsible for abstracting which protocol is used (co-located, remote ejb, or soap).

Setting bits question

I have a bunch of bytes of data I want to build in a byte array.
I looked at BitSet but I dont' think does what I want.
I'd like to be able to specify a start byte/bit, end byte/bit, along with the data I want to add.
Ex.
I'd like to be able to set the first 4 bits of the first byte or
specify stariting at byte 2, for the next 24 bits write this integer.
I know I could do a bunch of fanagling with and/ors,etc. but I was wondering if there is another way.
Thanks

A few weeks ago, I was playing around with something similar after reading this ACM article (http://queue.acm.org/detail.cfm?id=1563874).
To illustrate his point, the author created a bit-based record format used to hold U.S. Census data. Each record held information on one person. So, the first bit was the sex, the next 7 bits was the person's age, the next 32 bits was the person's income, etc. For fun, I created a Java program which could read and write these records. It was tricky doing this, but I got it to work.
One thing to remember that bothered me was that Java doesn't support the concept of "unsigned" like C does. So, when you read all your bytes into a byte array, you must deal with the fact that if the "left-most" bit of the byte is 1, the byte integer value will be negative. And you'll have to know a lot about bit shifting and AND. I looked into BitSet as well, but it didn't help me either.

Http to Abap Proxy communication with multiple queues generation in Recevr

Dear SDNs,
I need some help in the following scenario, appreciate your suggestions and help .
I am receiving the messages from sender to PI on http posting, from PI I am sending the message to SAP system using receiver xi communication channel ( receiver is abap proxy).
Sender will send the messages in QOS=EOIO, QUEueID=XXXt_100 etc parameters, when large volumes cases, it is getting delayed to process it using a single queue.
We are thinking to dynamically generate multiple queues in PI and send the same queue ids to receiver SAP system to process all the messages quickly in SAP System also.
Help /Clarifications needed:
1. XI receiver communication channel in pi does not provide any options to generate dynamic queue id based on payload content (using dynamic configuration) and sent it to SAP.
2. Module Tab in receiver communication channel also got disabled to add custom adapter modules, can we add custome adapter module on xi receiver channel to generate dynamic queue id ?
Really appreciate your immediate help and suggestions.
Thanks.
Suraj.

Dear Praveen,
Thanks lot for the immediate reply, we need to use EOIO, as the messages need to be processed in the same order we send and receive, there is no flexibility in QOS=EOIO, Appreciate if there is any other thoughts?
Thanks In Advance.
Suraj.

Http- XI-Proxy. Message stays in queue.

http->XI-Proxy async scenario. Message stays in queue in targret system.
(see screenshort at http://wapman.ru/screen.png).
When i click the name of queue and start processing manually, then everything works. Why message is not process automaticaly?

also you can register the Q's thru SMQR in XI box

PI to ECC via ABAP Proxy - Outbound Queue for HTTP

Dear Experts,
Is there any Outbound Queue for HTTP?
I've a interface scenario where the receiver is SAP ECC and the receiver adapter XI ABAP proxy. As I see in the communication channel the transport protocol used is HTTP. So I think could there be an outbound queue to manage HTTP connection when PI send the data to SAP ECC?
Just like when we are sending IDocs to ECC via tRFC, we could check if the IDoc has really been sent to ECC by checking in tcode SM58 (Outbound tRFC).
In case for ABAP Proxy via HTTP, is there any similar connection to SM58 (IDoc via tRFC)?
Thank you,
Suwandi C.

Hi Kandasami,
Thank you for the reply. I will check for it.
Hi Jens,
Yes, I mean somewhere after the SXMB_MONI in PI and before SXMB_MONI in ECC, is there any queue in between those two?
Thank you,
Suwandi C.

HTTP transport and Sun ONE Message Queue

How do I get the HTTP transport to work? The docs don't seem to be correct.

There are a couple of errors in the Sun ONE Message Queue docs that shipped with
the product.
The following are corrections for those errors.
Servlet configuration
Please note the following correction in the Sun ONE Message Queue 2.0
Administration Guide, Appendix B -
The class name of the HTTP Servlet in Step 4 of the "Configuring the Tunnel Servlet"
section is given as:
com.sun.messging.jmq.transport.httptunnel.servlet.HTTPTunnelServlet
The correct class name is :
com.sun.messaging.jmq.transport.httptunnel.servlet.HttpTunnelServlet
Client setup for HTTP support
1.The following connection factory attributes must be specified to use the HTTP
tunnel connection support.
JMQConnectionType :
Set this attribute to "HTTP".
JMQConnectionURL :
Set this attribute to the URL that will be used to connect to the Sun ONE
Message Queue message service (i.e. the URL for the HTTP tunnel servlet).
Note that there is no need to specify the JMQConnectionHandler attribute as
mentioned in the Sun ONE Message Queue 2.0 Administration Guide -
Appendix B.
2.Before running the client application, set the CLASSPATH variable to include
jmqutil.jar in addition to the standard Sun ONE Message Queue jar files.
This file is located at "/opt/SUNWjmq/lib/jmqutil.jar".
If the "jmqutil.jar" file is not included in the CLASSPATH, the client will get a
"java.lang.NoClassDefFoundError" exception for the class
"com/sun/messaging/jmq/util/JMQTimerTask".
3.If you are using an HTTP proxy, set "http.proxyHost" to the proxy server host
name, and "http.proxyPort" to the proxy server port number using the -D
command line option.
An example command line would look like this:
java -classpath
/opt/SUNWjmq/lib/jms.jar:/opt/SUNWjmq/lib/jmq.jar:
/opt/SUNWjmq/lib/jndi.jar:.:/opt/SUNWjmq/lib/jmqutil.jar
-DJMQConnectionType=HTTP
-DJMQConnectionURL=http://webserver:80/imq/servlet ClientApplicaiton

Queue error in HTTP receiver

I have a HTTPS receiver set up to send a file to the targer HTTP URL (external), file has been picked up but it's in queue with SYSFAIL status and message

Do I need to create a service in SICF for the web address?
Thanks,

Hi, tahnks every one for your answers but I am still not able to get to it.
Checked with the customer and they didn't receive it, the same works with webmethods fine. I changed the communication channel with RFC destination type G instead providing the URL direct. I am gettign the below error.
Do I need any thing specific for HTTPS communicaiton in PI or doest the HTTP adapter handles HTTPS? I think receiver doesnt want a soap envelope. I am sending a text file which has ras edi data and that's what the receiver needs.
