Advantages of PI against MQ

Hi All,
I need to build of list of pros and cons of PI against MQ. Following are the items I can think of now. Can you please add more to it?
Thanks for your input.
Pros of MQ
u2022     Ensure delivery of messages
u2022     Enables process to be attached to message received and sent
Pros of PI
u2022     Seamlessly system integration
u2022     Integrate system in many possible ways (adapters)
u2022     Enable integration of processes of different systems
u2022     SOA enabled
u2022     Synchronous communication (MQ only for asynchronous)
u2022     Message mapping
u2022     Flexible condition-based message routing
u2022     Flexible configuration to meet special requirements (like CC availability config, event-driven messaging, etc.)
u2022     Secure communication (SSL, message-level security, FTPS, etc.)
u2022     Better monitoring tools
u2022     Better audit tools

XI is well suited for connecting SAP systems with each other and with non-SAP. SAP XI provides an integrated workflow engine that allows defining adapters to non-XML protocols and mappings to convert data content from source to target format.
XI comes handy particularly incase of SAP - Non SAP interfaces where you can import standard integration content. Also XI has got sophisticated open standard adapter framework which is very easy to implement and custom logic can be implemented using Adapter module programming.
Advantages
u2022Monitoring is better than any other middleware product. It offers exhaustive monitoring features like message, performance, component monitoring etc, all of which can be used to track and rectify the errors. It follows a hub and spoke model.
u2022When you need to integrate with an SAP system XI has an advantage in supporting various SAP components and so on.
u2022Process functionalities inside XI to modify content in the communication channel on own defined rules for business purposes.
u2022Mappings and adapters are good as comparable with any other middleware product.
u2022Synchronous & Asynchronous communication is possible.
Dis-Advantages
u2022Web methods are particularly good if u have B2B kind of communication with their Trading Partners product.
u2022XI is lacking full-fledged Message Queue compared to other established Middleware products.
u2022It lacks in ability to process huge messages but SAP is working on that.
u2022It does not have a messaging layer exposed by APIs like IBM MQ-Series.
u2022It is not comparable to Tibco in terms of speed.
u2022SAP relies on other vendors except for a few adapters.
IBM MQ proven middleware in Market from long period of time .
The WebSphere MQSeries allows you to integrate back-end and external systems with WebSphere Commerce using WebSphere MQ as middleware. The supported software is MQSeries Version 5.2 or higher, with the MA88 product extension.
Advantages
u2022WebSphere MQ enables you to reliably and consistently integrate your applications, allowing you to fully leverage your existing software and hardware assets.
u2022WebSphere MQ eliminates the need to write complex communications code and offers a choice of simple APIs (Message Queue Interface (MQI) and JMS) that are consistent across the range of more than 80 supported operating environments, provided both by IBM and business partners.
u2022WebSphere MQ can reduce the risk of data being lost when applications, Web services, or networks fail. It also helps ensure that data is not duplicated and completes as a single unit of work or transaction.
u2022WebSphere MQ has Powerful development facilities that simplify integration tasks by providing a functionally rich and consistent application programming interface (MQI) across all its supported platforms. It helps make integrated programs portable.
u2022WebSphere MQ supports Secure Sockets Layer (SSL) for authentication, message integrity checking, and encryption for data sent across the Internet.
u2022WebSphere MQ reduces the time and skills required to be productive with a new File Transfer application that provides a simple GUI tool to move files across the MQ network with reliability.
u2022WebSphere MQ supports clustering for dynamically distributing messaging workload across available MQ resources.
Dis-Advantages
u2022The disadvantage of WebSphere/MQ is its awkward way to program and customize. MQ was originally designed as an application-programming interface (API) that was meant to be used as a program library for another programming environment, e.g., C++. Now MQ is mainly marketed together with IBM's WebSphere Application Server (WAS) for one main programming environment.

What's the cost of Labwindows run time engine

Dear Sir,
I have some questions about CVI and hope you can help me figure it out as usual.
1st, what's the advantage of labwindows against Labview? I know one is C programing environment and the other graphical environment. But the Labview seems more user-friendly.
2nd, What is run-time engine according to your definition? I know Matlab has similar component and is free of charge. Does the run time engine in Labwindows charge? If so, how much?
3rd, Previously, I thought labwindows is used to convert Labview program into C source code which is faster (how fast, compared with labview) and very popular in the industries, so companies do not have to buy labview and run it for just simple application in the field. But if the run time engine costs a lot, I can find no reason to use labwindows.
Thank you very much!

1) LabVIEW is a graphical based programming environment and
LabWindows/CVI is a C based programming environment. Both can be used
for similar tasks. Users familiar with C may prefer CVI. LabVIEW is
typically easier to learn if you are unfamiliar with both.
2)
The Run-Time Engine is a separate component that can be installed to
execute LabWindows/CVI programs and LabVIEW programs. It is free of
charge for both LabVIEW and LabWindows/CVI.
3)
LabWindows/CVI does not convert any LabVIEW programs into C code.
LabVIEW programs are already compiled as you write them, so you won't
need to convert them to C to use them. You should see similar
performance in similar LabVIEW and CVI code.

File naming on Russian and limitation on length of file names

Hi.
I post this message as a note for any users for whom English is not native language and in everyday practice they use native language on Linux systems.
Torrents and Linux
System:
OS: Archlinux x86_64
FS: Reiserfs
Locale: UTF-8
Client: rtorrent
torrent: http://torrents.ru/forum/viewtopic.php?t=1445641
Problem:
if one try to download this torrent with the help of rtorrent he see message
Hashing: Storage error: [Hash checker was unable to map chunk: Слишком длинное имя файла]
(this in on Russian, on English this is: 'File name too long')
Namely rtorrent couldn't handle this file
Белов А. В. - Микроконтроллеры AVR в радиолюбительской практике. Автоматика. Радиоэлектроника. Связь. Радио. Радиосвязь. Любительская радиосвязь.(2007)(336).djvu
(on Russian again).
The same message prints Transmission when one try to download this particular file.
Reason:
the name is exceeded the limitation on length of file name: 255 bytes. See, e.g.
$ echo 'Белов А. В. - Микроконтроллеры AVR в радиолюбительской практике. Автоматика. Радиоэлектроника. Связь. Радио. Радиосвязь. Любительская радиосвязь.(2007)(336).djvu' | wc -c
279
The problem doesn't depend on type of FS, it is in Linux kernel (Linux VFS). Reiserfs has limit in 4032 bytes on length of file name, Reiser4 has limit in 3976 bytes.
In this case NTFS is more advanced FS:
the limitation on length of file name is 255 UTF-16 code units (255*2 bytes).
Of course if one use 8-bit locale (e.g. cp1251, koi8-r and etc) then this problem for THIS file is not appeared:
echo 'Белов А. В. - Микроконтроллеры AVR в радиолюбительской практике. Автоматика. Радиоэлектроника. Связь. Радио. Радиосвязь. Любительская радиосвязь.(2007)(336).djvu' | iconv -f utf-8 -t koi8-r | wc -c
162
Nevertheless there is no guarantee that someone won't face with longer named files and in that situation the advantage of NTFS against any Linux FS is evident.
Info about FS limitation is taken from wikipedia.
I would glad to hear comments and suggestions about this particular problem (because I don't know how to download files of this torrent and store them on my Linux box).
P.S. As I understand FreeBSD has the same problem in this case.
P.P.S. I think that this problem could appear for example on Linux which serves as samba server (file server) when windows user want to place file with native alphabet letters in name on server.

This is a reported bug.

Experience in programming LabVIEW with HP E1432A

Can someone share his/her experience in controlling HP/Agilent E1432A VXI module?
The last posting on the forum about HP E1432A was dated in 2001. I know NI has a LabVIEW plug&lay instrument driver (wrapper) now for the E1432A module.
How easy is it to synchronize multiple E1432A modules in a VXI chassis? and what is maximum numbers of channel and sampling rate you used successfully via an NI VXI-1394 (FireWire).
You help is most appreciated.
Regards
Ian Ren

Hi, Chris
I used the Agilent E8491B, IEEE1394 Firewire interface. With MS Windows 2000 & LabView
I think i had 4 E1432A cards (64 chns)
The COM measurement engine software was a free down load from VXI Technologies who have taken on production of the 1432 type of cards from Hewlett Packard / Agilent it enables you to use active x to control the cards it originally was also provided free from Agilent. But looking at their (VXI Tech) site today I do not see it, suggest you ask them they may have changed the name.
I add here the text supplied with the software help file to give you some more idea of what it does.
"ME4X library is created on top of the E1432 Plug and Play driver. One question is whether you should use ME4X or the Plug and Play driver when you create an application. ME4X has both advantages and weaknesses against using the Plug and Play driver.   The biggest advantage is the ease of use. It is possible to build an application with less than 1/10 of development time.   There are some drawbacks. To make the library easy to use, many functions are hard coded in the library. This will cause some compromise in the feature set and performance overhead. Although ME4X covers most applications, there may be a case where a feature you want to use is only available in the Plug and Play library.   If the measurement speed is more critical than flexibility, you may want to write a simple but not flexible program using Plug and Play.   Here are some general guidelines to determine which library should be used.
· If you want to build an application quickly without learning the hardware detail.     Use ME4X
· If you want to spend more time for data analysis and testing than application development.   Use ME4X
· If you are not comfortable programming in C or other low-level languages.    Use ME4X
· If you already have a working program using Plug and Play, there is no reason to use ME4X.
· Your application must run on HP-UX operating system.     Use the Plug and Play library
· You are a professional programmer, time for program development is not critical, and you want to build an application to get the most out of the hardware in terms of speed and features.   Use Plug and Play library
If you have never written an application for E1432/33/34 VXI modules and are still not sure whether to use ME4X or the Plug and Play library, I highly recommend to start with ME4X."
Hope that helps.

X6 vs C6. which is better

I Want to know does both x6 and c6 have same firmware and similer bugs or c6 has different firmware or less bugs?
On this forum I have seen numerious problems in x6.

Not in a way that wouldn't void the warranty.
The main advantage of X6 against C6-00 is the capacitive screen, which is far better than any resistive.
Apart from that, C6-00 has widgets and a phisical keyboard which can be useful.
But, if money is not a problem, I would suggest, like Psychomania said, a new Symbian^3, like C6-01 which is the less expensive of the new devices but has everything a mobile can have, and updates are coming shortly.

Best Practices on OWB/ODI when using Asynchronous Distributed HotLog Mode

Hello OWB/ODI:
I want to get some advice on best practices when implementing OWB/ODI mappings to handle Oracle Asynchronous Distributed HotLog CDC (change data capture), specifically for “updates”.
Under Asynchronous Distributed HotLog mode, if a record is changed in a given source table, only the column that has been changed is populated in the CDC table with the old and new value, and all other columns with the exception of the keys are populated with NULL values.
In order to process this update with an OWB or ODI mapping, I need to compare the old value (UO) against the new value (UN) in the CDC table. If both the old and the new value are NOT the same, then this is the updated column. If both the old and the new value are NULL, then this column was not updated.
Before I apply a row-update to my destination table, I need to figure out the current value of those columns that have not been changed, and replace the NULL values with its current value. Otherwise, my row-update will replace with nulls those columns that its value has not been changed. This is where I am looking for an advise on best practices. Here are the possible 2 solutions I can come up with, unless you guys have a better suggestion on how to handle “updates”:
About My Environment: My destination table(s) are part of a dimensional DW database. My only access to the source database is via Asynchronous Distributed HotLog mode. To build the datawarehouse, I will create initial mappings in OWB or ODI that will replicate the source tables into staging tables. Then, I will create another set of mappings to transform and load the data from the staging tables into the dimension tables.
Solution #1: Use the staging tables as lookup tables when working with “updates”:
1.     Create an exact copy of the source tables into a staging environment. This is going to be done with the initial mappings.
2.     Once the initial DW database is built, keep the staging tables.
3.     Create mappings to maintain the staging tables using as source the CDC tables.
4.     The staging tables will always be in sync with the source tables.
5.     In the dimension load mapping, “join” the staging tables, and identify “inserts”, “updates”, and “deletes”.
6.     For “updates”, use the staging tables as lookup tables to get the current value of the column(s) that have not been changed.
7.     Apply the updates in the dimension tables.
Solution #2: Use the dimension tables as lookup tables when working with “updates”:
1.     Delete the content of the staging tables once the initial datawarehouse database has been built.
2.     Use the empty staging tables as a place to process the CDC records
3.     Create mappings to insert CDC records into the staging tables.
4.     The staging tables will only contain CDC records (i.e. new records, updated records, and deleted records)
8.     In the dimension load mapping, “outer join” the staging tables, and identify “inserts”, “updates”, and “deletes”.
5.     For “updates”, use the dimension tables as lookup tables to get the current value of a column(s) that has not been changed.
6.     Apply the updates in the dimension tables.
Solution #1 uses staging tables as lookup tables. It requires extra space to store copies of source tables in a staging environment, and the dimension load mappings may take longer to run because the staging tables may contain many records that may never change.
Solution #2 uses the dimension tables as both the lookup tables as well as the destination tables for the “updates”. Notice that the dimension tables will be updated with the “updates” AFTER they are used as lookup tables.
Any other approach that you guys may suggest? Do you see any other advantage or disadvantage against any of the above solutions?
Any comments will be appreciated.
Thanks.

hi,
can you please tell me how to make the JDBC call. I triedit as:
1. TopicConnectionFactory tc_fact = AQjmsFactory.getTopicConnectionFactory(host, SID, Integer.parseInt(port), "jdbc:oracle:thin");

Installing Mac OS X Leopard on non-Apple hardware

Is it legal?
I'd like to play a little with Mac OS X for the first time and don't want to buy expensive Apple Macbook. I could buy legal Mac OS X for my laptop and need to know is it possible to be ok with that?

I had your doubts until April 2007. Than I changed. I will not go back to windows at any price. -believe me. I am 61 near 62. Started to use PC with Dos - Turbo Basic and Assembler. I installed several Windows verisions over Dos from Win 2.0 to Win4 Workgroups , 95 98 ... XP. XP was not bad after you got all the drivers and it is still on my 2 Macs into Parallel but I will never NEVER let windows surf the internet.
Apple software is planned to work with its hardware. Strange mix can be less expensive but I am sure you will not get the full improvement. I will not here explain all the advantage of Apple against Windows, you will find or have already found the explanation on magazines. I am not member of Apple and I am not 100% happy with Apple: if you go to see my posts about battery you will see I have also point to complain but I wish to be honest. The only thing I do notnlike from Apple is the suite iWork, I prefer to remain with MS Office, but that is my opinion.
Come on board with us, you will like it as we do. And about the price.. yes Apple is expensive expecially if you compare it with low end PC but you will understand why...

Where does WebLogic search the compiled JSP files?

Hi,
          I have done several tests with WebLogic and JSP files.
          I have observed that when the JSP is requested the first time it is
          compiled and saved in c:\weblogic\myserver\classfiles\jsp_servlet
          If I request the same JSP again, it won't be compiled again. I
          suppoussed it was because the compiled JSP (*.class) was created. Then I
          deleted the compiled JSP and when I call the JSP again it run perfectly
          without a new compilation.
          Where are really those JSPs?
          Thanks in advance,
          Chemi.

          No clue. But as somebody else has said, touching the jsp files WILL
          force recompilation if you gor your JSP engine setting correct (check
          seconds set to zero).
          My guess is that all AppSrv would have this feature, because it comes
          for free with usual classloaders, i.e. it would be MORE trouble to not
          have this feature than to have it.

What is the advantage of an apple mac laptop against a windows laptop

Very soon, I will be ready to change my present laptop with xp.
Baring in mind, I am told that cd/dvd's will be phased out shortly, at present, I use my cd rom drive for copying dvd films, so how possible is it to buy modern laptops with a cd rom drive.
But more important, why/how, is a mac better than a windows pc.

New Macs do not come with install discs. If you need to restore, repair, or reformat the startup disk, you would need to use OS X Recovery
Re optical drive > Does the new 13" Macbook Pro have a CD drive?
Macs are not as vulnerable to malware and viruses as Windows.
OS X: About Gatekeeper
Apple - OS X Mountain Lion - It's built to keep your Mac safe.
Currently, Mountain Lion v10.8 comes pre installed on all Macs.

Advantages of using BO over tools provided in BEx

Hi,
I am wanting to know if there is any documentation enlisting the advantages of using BO over the tools provided in BEx.
Also, what is the advantage of using BO analysing data from cubes in BI 7.0 than accessing data from SAP R/3 directly.
Thank you.

Hi
Advantages of BO (as well as other Query/Reporting) are that they provide robust end users interfaces
in terms of designing queries, reports and also run on a standalone desktop client. Their user interface is
easy to use and much easier environment to design manus, drop-down boxes/lists and buttons and also provide wizards to help users guide. These tools can also work against several heterogenous data sources.
There are several factors one needs to keep in mind when selecting 3rd Party tools for SAP BW. A few are listed below:
BO uses OLEDB for OLAP API via BEX query. This causes extra overhead because here you have BEX resources and then you add up BO resources to manage infrmation to/from BEX query over the OLEDB interface. Some vendors, like arcplan, use OLAP BAPI to access BW data. This API has somewhat lower overhead because it bypasses the OLEDB for OLAP layer.
As you know that BEX is MSExcel based. It is not easy to build sophisticatecd user interfaces without doing extensive VBA or Macro programming.
Thanks & Regards

Advantages of using proprietary driver

If I am not using compiz effects, is there any advantage to running the nvidia proprietary driver vs the free one? I'm guessing the most graphically intensive stuff I do is running photoshop in VMware and some elaborate screensavers?
Incidentally I wouldn't mind a desktop cube with dwm, but I guess that goes against the project's philosophy, and I'm fine with that.
Thanks in advance for any responses.

The only reason you should choose the Open-Source vs the propietary is for: Software Philosophy or Lack of support from the Propietary. The main reason people use the open source drivers is due to old hardware still being supported.
Performance wise the propietary is ussually alot better (ATI ones not so much). If you are using nvidia use the propietary since its 10X better. Otherwise I invite you to see what the opensource has to offer, youll be surprised of the progress these modules have made over the years.

Differences & advantages/disadvantages using OCFS & OMF

Differences & advantages/disadvantages using “OCFS & OMF” against “ServiceGuard & Veritas CFS” in a RAC implementation

>
Differences & advantages/disadvantages using “OCFS & OMF” against “ServiceGuard & Veritas CFS” in a RAC implementationYou need to read a book on RAC for this kind of question - Julian Dyke would
be my recommendation.
Paul...
When asking database related questions, please give other posters
some clues, like OS (with version), version of Oracle being used and DDL.
Other trivia such as CPU, RAM + Disk configuration might also be useful.
The exact text and/or number of error messages is useful (!= "it didn't work!"). Thanks.
Furthermore, as a courtesy to those who spend time analysing and attempting to help,
please do not top post and do try to trim your replies!

What to include to promote TFS against other similar tools?

Some of our TFS users are switching to different tools (Jira, GitHub, etc.) due to various reasons, such as better branch & merge functionality, remote dev advantage, open source and more current tools, and such.
As a TFS admin, I would like to communicate with the current users with something written, kind of like a promote of TFS against the other equivalent tools. But I would like it to be brief, clear, and making sense in an enterprise environment, I know
I can dig tons of info from internet, but I don't like to make it a long argument with tedious comparisons.
Can anybody throw some your thoughts if you are facint the same situation?
Our TFS users are mainly engineers from different teams, the teams work on very different products.
Thanks,

Hi Peter,
Thanks for your post.
This post is more relate to a discussion thread, not a question thread.
What or which features you or your team want to get from TFS? TFS is a powerful tools which could help through the list circle of project, you can refer to this official document:
