also i need to know which one is better jxl or apache poi.
Hi Ricardo_Lorenzo,
Whether to go for Multiserver instances or Single server, is totally a user requirement based decison. If a user has Single website, or multiple websites (of the same nature, in terms of functionality), usually the part of same domain, then they would go for Single sever installation. One single instance will handle the requests from all the websites (if there are multiple). There would not be a clustering/failover setup within ColdFusion and can use the ColdFusion Standard or Enterprise version.
On the other hand, if a user has multiple websites, all with different functionality and have multiple applications (may or may not) running, then they can go for Multiserver installation. Each website can be configured with individual instances. Clustering can be done within ColdFusion if needed. One would need an Enterprise license of ColdFusion for the same.
Hope this helps.

Anit Kumar

Pros and Cons of Quadro 4500 and X1900
o ok - i just ran into a delima where my G5 quad's Quadro FX4500 i just found out i cant use it in the MP - so now i have to re config my MP - and weighing the pro's and cons of getting another 4500 or just going with the x1900
i do alot of HD editing /motion/live type/shake work and working with apeture and photoshop
so pls id luv to hear the pro's and cons of the 2 cards mentionedThen I would suggest you opt for either the ATI X1900XT or the Nvidia Quadro 4500FX. The Nvidia 7300GT won't make the bacon with your requirements.
For me the differences mostly comes down to money. While I would find it hugely difficult to go with the Quadro given there's not the difference in performance to match the difference in price (you have to bear in mind that you can get the ATI card and 4GB RAM for the same money as the Quadro), it will perform better for your needs.
On a strictly performance basis the Quadro does appear to be the better option for you requirements. If it's your day job then you should be able to amortize the costs of the Quadro into your expenses. -
Pros and Cons between BEx client and Web access
Dear all,
I am quite new to BI 7.0 and have some question about frontend tools.
I am looking for a comparison material describing pros and cons of BEx client application and Web access in BI 7.0.
There are many tools in BEx suite and I am a bit confused about what fuctionality each tool has or what to consider to choose the right tool.
Thanks a lot in advance and appreciate any input.
Regards,
KazuyaHello,
Shortly speaking there are 4 tools and you need at least 2 of them:
1. Query Designer: you need it always as this is a tool for defining queries
2. Web Application Designer: you need it if you want create web reports
3. Report Designer: only if you want create formatted reports in web
4. BEx Analyzer: if you want to run queries in Excel (Analyzer is an add-in)
Help on BEx:

Pros And Cons Of iPod Touch And iPod Clasic?
I am upgrading from an older model of the iPod Nano and I was wondering if someone could tell me some of the pros and cons of each(iPod Touch and the iPod Clasic). I am torn between the two and would like some help deciding from someone who actually has had one or both of them. Please and Thanks in advance!
And when it comes to Apple Lossless it isn't just the 2nd gen Touch that skips. It is a problem that has cropped up on all the iPods at one time or another. Sometimes the issue goes away simply by reinstalling the music. Sometimes it turns out to be the rip that's defective (but the iPod nearly always gets the blame since the user never thinks to play the songs on iTunes before complaining). I've seen it go away after the user reformats the iPod's drive and sometimes an iPod update solves the problem.
So it isn't just the 2nd gen Touch and you have a viable temporary work around. Deal with it, sell it, or return it. Whining about it won't make it better and I suspect you are like most Lossless users - wasting space because you think what you are hearing is better when you really can't tell the difference most of the time. -

To fetch data from Oracle store procedure, you can use a Script Component as source to call the Oracle stored procedure by using System.Data.OracleClient OracleDataReader, and get the rows and add them to the pipeline buffer. For more information, please

KM Cache and iView Cache - Pros and Cons
Hi All,
Can anyone tell me which Caching mechanism is better - KM Caching or iView Caching ?
What are the Pros and Cons of KM Caching and iView Caching ? Which type of caching is recommended ?
Any kind of help is appreciated.
Regards,
AdrenHi Adren,
As to my understanding, with Portal Cache, we can achieve the following:
1. Significant improvement in the interface response time
2. Unnecessary, additional page generation (re-rendering) is avoided when you call a portal page
3. Web browser-like caching for server-based, dynamic pages in the Web (such as the BW Application Web)
Cache monitor to monitor the current status of all active caches in your system landscape. The data displayed in the cache monitor can be used for evaluations
KM cache might eb better than Iview cache.
Please check the below links we might get soem info about the type of cache which is preferable.

I am interested to know the shortcomings of L73x. It's better to know before I buy than to shed tears later. I understood that not any phone can feature all functionalities still it's good to know the pros and cons.
senba wrote:
I will expect nothing short of the features which the predecessor / lower end variant was delivering.
The Nokia model-numbering scheme gives a false impression. For example, a 22€ Nokia 2730 classic had a better sound equalizer than the Nokia 808 PureView. For example, a Nokia Lumia 930 did not get Glance Screen although the Nokia Lumia 630 and Nokia Lumia 1520 do.
The numbers do not indicate lower/higher but again just these target audiences. I do not like comparisons because they go wrong easily but let us go for this: The first/front number is very much like grades in school. There is 5th grade, 6th grade and so on. As you expect from a class, not all pupils are perfect. Some pupils have a deficit in that feature, some are outstanding in that ability. That continues over the years, and as consequence a 9th grade pupil is still not perfect – not in every aspect. In some areas of knowledge and expertise, a 6th grade might be better, in same areas. Think about the numbering scheme as an academic year in school, I would not go for lower/higher in proficiencies just from the number.
Predecessor/successor – same here. Nokia never aimed to create predecessors. Neither in model numbers, nor in feature set, nor in price tags. The current naming Lumia x2x versus Lumia x3x looks like that, but is more about a ‘generation’. Although normal guys like you and me love to stick to the well-known, Nokia hates to accompany us on our journey with a successor every year – like others do quite well.
Nokia; no predecessor/lower here. Successor? Improvement in feature set? Nokia: ‘Please go for the one your network operator offers at that time; we have done it right for you, already.’ Hopefully, hopefully, Steven Elop as a Master of Computer Science – a software man – finds the vim to tell those hardware guys about the expectations of end-users, one day. Until then, do not expect too much from them.
senba wrote:
Can [Glance Screen] be introduced in a later stage through some OS updates[?]
I do not expect this to happen because the software is written, therefore my guess: hardware is missing. This is not like sound equalizer, Miracast, or FM radio – cases which Windows Phone had no software support when the hardware was finished. Anyway, just a guess. But again I would not expect Glance Screen for the Nokia Lumia 735. -
Hi All,
I have read that SAP Pi 7.3 has java based IDOC and HTTP adapters. I would like to know the pros and cons of IDOC AAE and also the cases or scenarios where the adapter cannot be used.
Please help me with this.
Regards,
meenakshiPI 7.3 can have either java only installation or both java and abap stack. I meant both local (JAVA) and classical engine (ABAP AND IE) processing
Pros: AAE processing is faster and certainly boost performance than traditional or classical IE engine processing. Same for both HTTP and Idoc adapter.
Cons: Monitoring capabilities are not great at Java only installation level. AAE monitoring capability is very limited at this time. Also BPM related scenarios cannot be seamlessly migrated to java stack (AAE) level. We need to wait for sometime on this. -

Is this the only approach to meet this requirement or is there any other way to crack it. sharepoint techies please help me.as you described the scenario of the event that it should happen when user upload excel to a document library. Event Receiver is your best bet. However if you would have a requirement that users can send excel files any time to a network file location and
you want to pick it, read it and create list items etc. You would write a sharepoint timer job that would run every 10 minute to check for file and if available on the network drive, perform the operation etc. so that users who send excel file does not need
to come to the sharepoint etc. You can see that you have Event Receivcer option or Timer job option OR you would write a console application to trigger the code at a scheduled time on sharepoint server etc. so you are using the event receiver in the correct
scenario.
