SOA interfaces and https

Hi all,
I would like to know your feedback and experinces regarding secure communication between SOA-interfaces (2-Way Communication) and different layers for using http and/or https URLs. In one use case, we can define 3 variants for securing of communication:
1- Internet (https) --> Intranet (http): client uses https --> Hardware Loadbalancer is able to use the certifacte and then intranet OHS-SOA-Interface communicate with http
2- Intranet til OHS is using secure communication: client uses https -->Hardware Loadbalancer is able to use the certifacte the forward to OHS (https). Then intranet (OHS) has certifaction and use https but SOA-Interface communicate with http
3- all of layers using certifcation and communication till SOA-Interface is secured (https)
I want to compare approach 1 and 3:
A- What is the impact of Performance in solution 3? has secure communication more overhead?
B- I consider the 3. solution as a solution with highest security level. Is the solution 1 secure for critical transactions?
Thanks in advance,
Moh

Hi,
In general secure communication (https) has more overhead and this is expected .
Option 1 looks better since the client request comes as https (secured) and the rest of the communication between OHS and SOA is non secured.
But I agree with you that option 3 is highest security level and it totally depends upon your convenience as to which one to choose.
Thanks,
Sharmela

Firewire Interface and Microphone Choices?

Was looking to drop no more than 500 dollars on a firewire interface and less than 175 in a microphone to do some decent quality recording onto my MB (primarily trumpet, ukulele and acoustic guitar). For the interface I've been looking at the:
Apogee Duet
http://www.musiciansfriend.com/product/Apogee-Duet-Firewire-Interface?sku=234444
And for the mic, the:
MXL 992
http://www.musiciansfriend.com/product/MXL-MXL-992-LargeDiaphragm-Condenser-Micr ophone?sku=273162
Any feedback on these two products or have any other recommendations? Thanks for the help.

If you don't need a lot of inputs and outputs, but are looking for decent sound quality, the Apogee Duet seems like a good deal.
I'm not familiar with the mic.

Apple TV audio through interface and monitor speakers?

Hi all,
See following pic of my setup...
My question is as follows....
When Macbook is linked to tv via airplay, which is my normal setup as I produce music and use both screens, the sound output is set through Saffire audio interface and comes out the monitor speakers and all is good with the world, however, I want to be able to sit back and watch the apps on Apple TV as is shown on the big screen there ie. Netflix/NBA TV, but still using my computer soundcard and hence through the monitor speakers instead of it switching back to the TV sound.
IS THIS POSSIBLE???
Thanks in advance for any help.

Thanks for the response vazandrew. I've looked further into what you said and the solution is as follows;
http://www.amazon.co.uk/eSynic%C2%AE-Digital-Optical-Coaxial-Converter/dp/B009ZR 7IB8/ref=pd_sxp_grid_i_0_2
Ditial optical out to toslink audio converter, then out the converter to RCA/Jack etc.
Hope this helps anyone else with same question.

I have SOA suite and Jdeveloper, what do i need more for BAM ?

Hi
Thank you for reading my post
I have installed both soa suite and latest version of jdeveloper
I can see BAM node under connections node but i do not know how should i add the bam server connection.
so my questions are :
-should i install the bam server seperately or it come with ORACLE SOA suite?
-if i should install seperately, where is hould find it?
-if it is inside the SOA suite How i can activate it and add it to my Jdeveloper?
thanks

\BAM is part of SOA suite, but BAM should be installed separately, Go to http://www.oracle.com/technology/products/integration/bam/index.html for details.

How to use SOA Suite in conjunction with SOA Analysis and Design Tools

Hi everybody,
I am a novice in this field and I need some help regarding integrating analysis and design tools with SOA Suite.
We used to analyze and design with Oracle Designer and use its powerful form generator to develop a system. It almost covered all the software lifecycle and kept the traceability between anlaysis,design and implementation.
I have studied about the SOA concepts and read some papaer about SOA Suite. I have also installed the SOA demo based on SOA Suite and I found it absolutely amazing, but my problem is that It seems oracle does not have any tools for SOA Analysis and Design. am I right? if so, How can we analyze and design a system based on SOA concepts and implement it using soa suite in such a way that keeps traceability? What tools is used for this purpose?
It seems that IBM have some tools like Rational Software Architect and Rational Suite which enable people to design and analyze based on SOA concepts and then generates some pieces of code (like oracle designer in old days) but is it possible to design in these tools and then generating codes for SOA Suite ? (for example generating a bpel file from a design model)
As I told before I am a novice in this field and I would be so grateful if other users can share their expriences regarding this matter.
Any help would be highly appreciated.
Thanks in advance,
Navid

Here is my problem. I use soapui trigger a test msg to PI system. But in the sxmb_moni, only sender service is there.
The sender interface and sender namespace is missing. And the msg has error called: :INTERFACE_REGISTRATION_ERROR.
Which means I do not have a inbound interface to process the msg.
But I suppose to redirect the msg to business system.
Here is the configuration:
reciever determination: soap sender service, soap outbound interface, soap interface namespace --> reciever business sytem.
Interface ditermination: soap sender service, soap interface --> receiver interface, receiver namespace.
Sender agreement: soap service, soap itnerface --- soap communication channel
receiver agreement, soap service---> receiver sevice, receiver interface, reciever namespace and reciever cummunication channel
define of soap sender adapter:
soap sernder, with use encoded header and use query string checked and qos as exactly once.
Anyone has any idea here? Many thanks! And most strange thing is yesterday it works and today it failed.
Please kindly help here.
Thanks a lot,
Leon

Hi guys,
thanks for the input.
Hi Sven,
I have input default interface and namespace.
Hi sivasakthi,
Regarding mistype, it may happen, I will do it again right away.
And the URL is generated by the wsdl toolkit in the directory.
I marked use encoded header and query string in the communication channel.
I will generate the wsdl again and test it again.
Regarding URL(endpoint of web service):

Thanks for the response, but I do not have a midi interface. I am using a midi to usb connector cable, thus bypassing the need for a Midi interface.
The Mac reads the USB cable as a midi device, but not the keyboard that I am trying to use as a controller. I have tried it with my korg sp 300 and with my Nord Electro 2.
Thoughts?
Thanks,

Tristan...
This is what you have, correct?
http://www.alesis.com/usbmidicable
This from Alesis..
"The AudioLink Series USB cable receives and outputs MIDI signal thanks to its internal interface. The USB-MIDI Cable connects plug-and-play to your Mac or PC for an all-in-one USB-MIDI solution."
Notice, -internal interface-. What you have is a simple USB MIDI Interface. Most MIDI interfaces are USB.
My point is (was), MIDI OUT of the Korg goes to the connector marked MIDI IN on the Alesis, those new to MIDI often get this wrong.

BadRequest: Virtual machines with secondary network interfaces and virtual machines with no secondary network

I'm trying to create an "ExtraLarge" VM with multiple NICs. The New-AzureVM returns the following error:
BadRequest: Virtual machines with secondary network interfaces and virtual machines with no secondary network
interfaces are not supported in the same deployment, also a virtual machine having no secondary network interfaces
cannot be updated to have secondary network interfaces and vice-versa.
But I have no other VMs. Or at least I did and then deleted them and all their disks. The service has no deployments (either staging or production).
Why is New-AzureVM complaining about a mismatch of VMs with and without secondary network interfaces when no other VMs exist?
I have tried many things to fix this, including the deletion of ALL of my resources. I have deleted and created the service many times, both with an affinity group and without. I have a screen print of the -debug output if your interested.
Thanks for the outstanding help.

Include only interfaces and package-level comments -

hi jd forum -
forgive if this is covered elsewhere. i've found references to -include, -exclude, and 'docset', but i can't find these in the documentation at http://java.sun.com/j2se/1.3/docs/tooldocs/win32/javadoc.html (maybe it's for a different version).
i want to only include documentation for interfaces and exclude the classes -- and / or include documentation on a filename basis -- like 'document only IBI*.java.' also, i want to include ONLY package-level documentation (package.html) for some packages but not the javadocs for their associated classes...
are these things possible? i've looked into -package, -protected, and -public, but these don't seem to cover it.
thanks in advance;
-m

The -include and -exclude options and @docset tag were considered for 1.4 but then decided against by the Javadoc team as we look for other solutions.
You can document all public interfaces by passing their source filenames in to javadoc. Say, if the source files are in ./src, then:
javadoc -d docs ./src/com/package/Interface1.java /src/com/package/Interface2.java
You can use the wildcard asterisk here as well:
javadoc -d docs ./src/IBI*.java
There's no way to document the package-level documentation without the associated classes. Javadoc 1.4 has an -exclude option, but it works only to exclude packages from the -subpackages option, which is a shortcut for passing in package names.
A workaround could be to put the package.html file in a doc-files directory and then add a link to it in overview.html. It won't be processed, so won't have the navigation bars on the top and bottom, and cannot be automatically linked to from other places (index).

WCCP Configuration HTTP and HTTPS

Looking for anyone that might have a clue in on this, im attempting to configure a pair of routers to use WCCP to redirect HTTP and HTTPS traffic to two content keeper devices. The network im building is going to be used for a guest internet connection where defining proxies on end devices would be unusable.
I'll drop the configs in below but for now what i have are 2 cisco 3925 routers configured for HSRP. 2 content keeps running squid for the cache engine. with my current configurations, I have wccp web-cache and wccp service 70 configured (all 4 devices are available/usable in both services). this is a layer 2 setup. HTTP traffic is picked up and redirected to the content keepers without issue. https traffic does not appear to be detected by the routers. I have chosen not to use ACLS for WCCP and use the redirect in because we want to capture http(s) traffic from all hosts.
for HTTP, I see hits counters rise on the router under show ip wccp, i see hit counters for the content keepers increase, i see http traffic on the firewall from the content keepers and I get the web page on the device
For HTTPS I do not see hit counters under wccp increase, I do not see any traffic on the content keepers bridge, and i see traffic on the firewall from the hosts orginal ip address.

Show details and show service attached.

Hello Josh,
1. Yes, port-specific ACL is not supported. But it is not a big problem. Usually on WCCP server you can configure very specific bypass (Cisco WSA supports that - do not know about Sophos). For bypassed traffic WCCP server will reinject that packet in GRE and send back to ASA which will decapsulate it and send as normal packets.
It's a good design, because you can have very granural bypass policy on WCCP server.
2. Yes, configuration is correct, although it's better to be more specific (not send all traffic to WCCP if there is no need for that).
3. Yes, you can use deny in redirect-list to exclude traffic.
4. WCCP keepalives are being send by WCCP server by default every 10 seconds. If ASA does not see that replies for some time it marks server as dead and uses other ones.

HARDWARE interfacing and software routines

Hello there,
I am interested in finding out a really basic tutorial/note which will allow me to work with the basic communication protocols like SPI , RS 232, etherner, USB, etc. I am looking for tutorial with BOTH HARDWARE interfacing and software routines.
Multiple websites will be ok for me.
I have searched wikipedia and lot of power point presentations but was not successful in landing up with a COMPLETE tutorial which explains the hardware interfacing connections and software.
If you guys can suggest an evaluation kit where i can pracice the above interfacing and software routine..... by all means do let me know.
Looking forward to your reply.

Technically you can do everything you are talking about for free provided you have the internet tool kit installed (Full Development Suite) and depending on what level of detail you plan on going into.
If you want to play with RS232 you can start with just taking the existing Labview example, "Basic Serial Write and Read.vi" under Labview Help -> Find Examples. You can find a serial cable and connect it to your Comm port. On the other end of the Comm port you can insert a small wire to short pin 2 to pin 3 (TX to RX). You will then be able to send and recieve data on the same vi. I would look at wikipedia to learn more: http://en.wikipedia.org/wiki/RS-232
If you have the internet tool kit install then you can do all kinds of stuff with just a regular internet connection. For example any place where you can Telnet you could test using the "Telnet Line Client.vi" provided by Labview. Again I would start by consulting wikipedia if you have questions: http://en.wikipedia.org/wiki/Telnet
If you are trying to do everything down to the hardware level then this is a little more involved. Again break your post into smaller pieces and repost on the Labview forum and you will have better luck getting detailed responses.
You should not have to spend much money to play around. You can build a lot of this stuff yourself or you can purchase very cheep if you shop around. For example you can implement SPI using a parallel port but you need to know what your target SPI interface will be. Regards, SS

QoS - EOIO in RFC and http/SOAP adapters

Hi all,
I need to have the QoS as EOIO in my interface where I am using RFC Sender adapter and HTTP/SOAP receiver adapter and using BPM Integration process.
I have seen in the adapter attributes that these 2 adapters support the EOIO. I don't know how to specify this service in the adapters.
Is there any special way of specifying this?
Any help in this regard is highly appreciated.
My interface is async and we are at SP 14.
Thanks
