Proxy to JMS Scenario: switch from sync to async proxy,does it makes sense?

Hi @all,
i've implemented a sync proxy to JMS scenario that works well. Backend is ECC 6.0 and Middleware is PI 7.1.
Business Case: Run a request with a number and get a response back with a corresponding entry for the number. That means, there is always a response expected.
Now the following thing appears: the receiver system could not handle many calls at one time (200 calls are planned at each run), the calls reduces the performance. Now gys at receiver system likes to develope a buffer of 10 seconds between the requests to handle some kind of load balancing with that. That means for the request that it the response takes +10 seconds back to backend. It is also possible to handle that in SAP backend with a waiting-statement in coding, so there is no need to go from sync to async - but the customer requested us to implement this scenario in async.
JMS is always async, I know. But the Service Interfaces for Inbound and Outbound are of mode sync - so I can call my outbound Interface class in backend with Importing Output and Exporting Input.
My question is: makes it sense to go from sync to an async scenario?
And how looks the coding in backend for the response? I guess that it only makes sense to switch to async when no response entry is needed (example: for write operations).
Thanks in Advance,
Stefan

I don't think you need 2 scenarios for this. Just one is enough with different RDs.
Over all in this case you have to re-create/modify the service interfaces and also you have to create 2 interface mappings. You have to also create the new inbound and outbound proxies since service interface mode will be changed. For outbound proxy the code can be reused and for inbound proxy also logic and code can be taken from your old code.

Upgrade from G5, dual2.7, PowerPC, does it makes sense??

Hi,
I wonder if somebody can give me some advice.
We have two G5, dual 2.7, PowerPC, 4 GB ram, running 10.5.4.
Beside the normal office stuff we run Aperture and Lightroom with large image RAW files (Canon 1DsMark3).
We have been on the road for two years and I wonder if it makes sense to upgrade our computers?
1. Is there a big speed difference between the Intel and PowerPC?
2. Are there any CPU upgrades available?
3. Would be our PowerBook Pro, 2.33 Intel 2Duo, 2GBram, faster then the "old G5's?
Would be great if somebody could give me some advise.
Thanks
Rolf

At this point probably worth waiting for '09. Are there differences? yes. And all indications are that Snow Leopard will be Intel-only. And wait for quad-core to come to laptop and desktop.
A MacBook Pro is fine for on the road maybe but not where you need more storage and memory options. Or better GPU performance.

Proxy-2-JMS Scenario: more than 10 additional JMS properties possible

Hi @all,
we're implementing a Proxy-2-JMS-Scenario. The JMS reciever side needs unfortunalety more than 10 additional JMS properties. In XI/PI the maximum number of additional JMS properties is 10.
Do somebody know a good workaround in PI how to deal with it?
Thanks and best regards,
Stefan

Hi @all,
there is no way to handle with more than 10 additional jms properties for jms header.

Needs steps in ID(configaration) for Proxy to JMS scenario

Hi All,
Please can anybody give steps for Proxy to JMS scenario in Integration Directory .
Thanks in advance.
Regards,
Kalpana

kalpana,
Create two communication channels in ID. One for Proxy(XI adapter) and another for JMS(JMS adapter). Then sender agreement, receiver agreement, receiver determination and interface determination.
For JMS adapter please see this weblogs:

How can I restore a single image from an aperture time machine backup, do I have to restore the entire library? that does not make sense

I hope there has been found a more efficiant solution for this, how can I restore a single image from an aperture time machine backup, I really hope I don't have to restore the entire library? that does not make sense
any suggestions?

Did you try browsing your backups in the Finder ? That is, do not go and "Enter Time Machine". Instead, navigate to your Time Machine backup via Finder and then manually go to the time period (by folder name) you are looking for ... when you find your Aperture library you can then "Show Package Contents" and find the Master you are looking for.

Currently my internal drive is full due to Aperture. I want to work with Aperture from a external drive verses my internal drive. In addition, I want to back-up my work to another external drive. Is this easily done? Does this make sense? Pros / Cons...

Currently my internal drive is out of space due to my Aperture files. I want to place Aperture on a external drive to work from verses in intnal drive. In addition, I want to back-up all my work to another external for safe keeping. Once I move aperture to the external, I want to delete it off my internal drive. Does this make sense to do? Pros / Cons....

It is common for people to move their Aperture, iPhoto, iTunes etc. files to an external drive when those files become too large to conveniently keep on the internal drive.
The best approach is probably to keep the applications (iPhoto, Aperture etc.) where they are now, but move the files (photos, music, videos etc.) to the external drive.
You should set up a process to regularly backup all the files from both the internal drive as well as the external drive you'll be using. Here are two approaches:
(1) Use Time Machine. You can configure Time Machine so that it backs up both the internal drive as well as the external drive, all to a third separate backup drive. This is done via the Options button in the Time Machine preference pane.
(2) You can use a "cloning" program, such as SuperDuper, Carbon Copy Cloner, to make complete copies of files on your internal drive and that external drive. One way to do this is to use a very large disk for the backups, and to partition it into two backup drives, making one dedicated to the internal, the other dedicated to the external.
Two separate types of backups are recommended. I use both (1) and (2) above, and I disconnect and shut down the clone type backups when not being used. That way a power failure or surge that might destroy the original disk(s) plus the Time Machine backup(s) would still not damage the backups made under (2).
Don't delete your original Aperture files until you have verified that they are working properly from the external drive AND you have made a backup of them.

Technical Scenario Switch: From Standalone To Extended Classic

Hello,
Currently we are preparing the system to change the technical scenario from standalone to extended classic (SRM 4.0)
While the Customizing steps are clear, it isn´t so clear how the data that already exist in the system will behave after the scenario switch.
Before the scenario switch, the purchasing department is closing all open SRM local purchase orders.
Someone has already done this kind of scenario switch?
What were the problems you encounter?
Regards.

Hi
Before talking about de-activating ECS or not in this BADI, this scenario must first be activated.
This is done via the customizing point "Activate ECS": just flag the check-box, and all you classic items (i.e. those for which a backend has been determined) become extended classic.
Here is the SRM - IMG path:
SRM Server --> Cross-Application Basic Settings --> Activate Extended Classic Scenario.
You can then fine-tune the scenario by using the BADI BBP_EXTLOCALPO_BADI.
Note- The BADI BBP_EXTLOCAL_PO_BADI can be used to activate the classic scenario based on the proguct categories .
You can choose to have the 3 scenarios working on the same SRM system depending on product category (standard) or any other business rule through the BADI BBP_EXTLOCALPO_BADI. The BADI is mandatory if you want the Classic and the Extended Classic to work together
Exactly, this BADI allow you to implement your own business rule for backend determination in a multiple Backends environment (Standard customizing is only based on Product categories)
As soon as you use BADI BBP_EXTLOCALPO_BADI , you don't have to use the ECS scenario activation customizing point (the rule is overwritten with the BADI result). The BADI BBP_DETERMINE_LOGSYS will only help in your case, if you have several Backend where to create PO documents.
PS: be aware that in ECS scenario you will no longer be able to create PR or reservations in R/3.

When trying to sync my I Phone 4 to I tunes I am getting a message: Unable to Data class information from Sync Services. What does this mean?

When I-tunes is trying to sync my phone, I get a message regarding Data Class Information from Sync Services saying they were unable to do this. I have no idea what this means. I have not been having any problems with syncing info from my computer to phone until just now. I am trying to install new alert tones from an app that I purchased. The alert ones are now in my library on I-tunes and they play but they are not syncing to my phone. The snycing options is not available in my library and when I try to manually sync these tones, nothing is happening. I recently purhcased ringtones from the I-tunes store and from my phone and they downloaded with no problems and are synced onto my computer and are showing up in the same library list as the tone alerts which I cannot seem to sync. I have no idea why this is. Please help!

In the course of your troubleshooting to date, have you worked through the following document?
iTunes for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert

Switch from syncing with palm to outlook -- not all calendar entries appear in outlook

I've been syncing (usb/cradle) my treo 700p with palm desk on a vista laptop with no problems, but want to switch back to using outlook 2003. Everything EXCEPT calendar syncs fine. When I sync calendar nothing later that 2004 appears -- these were items that were in outlook when I switched to palm. I've tried deleting them in outlook and resyncing with 'handheld overwrites desktop', but still only the old ones appear! Please help!
Post relates to: Treo 700p (Verizon)

Hello saltiel,
Welcome to the BlackBerry Support Community Forums.
I would recommend going through the following knowledge base article about how to merge multiple calendars into one calendar on the BlackBerry smartphone.

How do I switch from syncing with iTunes to syncing using iCloud without getting duplicate Ono

Hi
I have been syncing my IPad to my mac using iTunes. I would like to start using the cloud to sync my
Contacts, calendar and a small amount of documents. I'm not so concerned with my pictures, video's or
music. they not as time sensitive and can stay with iTunes.
   Do I need to do anything besides disabling those sync functions in iTunes and enable themin iCloud?
I don't want to get a duplicate contact list or calendar. Which are the two main things I need to keep more
Current.
        Would I be better off staying with iTunes? I'm on the same wifi network most of the time. My
reasoning behind changing sync methods is the fact that iTunes only syncs when I charge my IPad
and I need A more current sync than once every day or so. (Especially for my calendar.)
   I'm sure the info is buried out here somewhere but I have vision problems which make combing
through the vast amount of info out here a little difficult for me.
     Any thoughts, advise or input would be appreciated.
   Ron

No help? I can't be the only one that backs up to iCloud and buys right from the iPad that then wants to sych with their desktop.
BTW, it's not jailbroken.

Acknowldegement in asynchronous scenario: is it sync or async

Dear community,
in an asynchronous scenario with a fault message type defined for the inbound interface, the handover of a message from XI to receiver consists of two steps:
Step 1: XI will send a message to the receiver
Step 2: The receiver will acknowledge positively or negatively.
Will Step 1 and Step 2 be handeled synchronously or will it be handeled asynchronously for async scenarios ?
The background of this question is resource-related. If the processing of a message is synchronous, processing of these two steps would block resources, which would be problematic for higher volumes.
Logically it seems as if this would all be async but I could not find a detailled spec and I need to know for sure.
Thanks a lot in advance !
Jochen

Hi Jochen,
if you want to have the result of a message at the receiver you have 2 alternatives:
Synchronous:
+You get the errors at once
+You know very soon, what happend
-Bad performance, bcoz processing time may be for minutes stopped
-no connection (receiver offline) leads to an error
Asynchronous with acknowledgement:
-You get only sometimes an error acknowledgement
-The calling programm has no direct information
+Much better performance
+Queing mechanism allows automaticly and manually restart
Usually you try to build, if possible, asynchronous scenarios. But it depends on requirements.

Udo

With ios 7 switch from photo to video camera does not work neither on iphone 4 nor on ipad 3rd generation retina what can be the problem ?

With ios 7 installed 2 days ago on my iphone 4 and on my ipad 3rd generatiion it is not possible to switch the photo camera to video camera . What is the problem ? Did someone meet the same problem ?

Did you try swipe up and down to change?

The flash on my camera is not working. Even when I switch from auto to on it does not work.

I have witches from auto to on and the flash for my camera still doesn't work. I have not dropped it and the flash was working just 2 days ago.

Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
