Pros and cons of EPM and Classic Application.

Hi All Experts,
can any one tell me what are the pros and cons if create EPM Application
and pros and cons if we create Classic Planning Application
this is really urgent we have to submit this to our client as soon as possible

Hi,
The main difference between using of classic and EPMA is I think hidden in the first letter of EPMA. EPMA is for Enterprises where multiple performance management applications are considered applicable. When you have an HFM application, a planning application, a performance scorecard application, a couple of essbase cubes around and lots of reports pulling data from all these, sharing data and metadata becomes crucially important. And no mistake, classic planning is as good as EPMA planning and easier to handle, however, if your company or client is thinking of having a total EPM solution in place, then EPMA is the right choice. However, since you can always convert your classic app to EPMA but you've got only one bullet to fire, it might be wise to stick with classic application until your client/company starts imagining that sort of ambitious goal.
Cheers,

Pros And Cons of Subforms and Groups?

Does anyone know of any pros and cons related to how things are grouped, either via an object group or a subform? Are there any specific reasons to use groups and not subforms - subforms and not groups?
For those who care to know a little more, not just questions...
In designing my forms I have taken this approach:
Groups (created by selecting Layout > Group) - I use groups for grouping simple objects (Text, Lines, Rectangles, etc.) which build the "static" portion of the form.
Subforms (created by drawing, or "wrapping" objects together) - I use Subforms for field objects (Text Fields, Numeric Fields, Decimal Fields, Check Boxes, Radio Buttons, Date/Time Fields, etc.) which act as the "live" or "dynamic" portion of the form.
I like this way of organizing the objects. It seems to make "sense" at least to me, and it also helps in terms of aligning objects, and so on. However, of course, it is not necessary to segregate the objects this much. So what is the preferred or recommended method? All opinions or suggestions are welcome!

Actually, there's a big difference between using groups and subforms to relate objects to each other although if you don't use any scripting and/or data binding, you probably wouldn't notice much difference.
Once you get into scripting and/or data binding, the use of groups and subforms makes a significant difference because groups (which are actually <area> XFA objects) are "invisible" when it comes to scripting and data binding.
This means that if, on a page, you had 4 text fields, each named TextField1/2/3/4, and TextField1/2 were grouped while TextField3/4 were wrapped in a subform (named "Subform") and you needed to access these text fields from the context of the page, you would do:
TextField1 OR TextField2
because they're grouped with an <area> tag which is transparent in the Object Model. If, on the other hand, you needed to access the 3rd and 4th text field, you would do:
Subform.TextField3 OR Subform.TextField4
because subforms are defined in the XFA Scripting Object Model.
The use of groups and subforms also affects data binding. That is, it affects the way XML data imported into your form is used to populate values of fields. For instance, if your data looked like this:
<data>
<TextField1>1</TextField1>
<TextField2>2</TextField2>
<TextField3>3</TextField3>
<TextField4>4</TextField4>
</data>
and your form had TextField1/2 grouped into a group named "Group", TextField3/4 wrapped into a subform named "Subform" and then another TextField3/4 which were siblings to the Subform and Group objects but placed
prior to the Subform object in the object hierarchy, importing the above data into the form would populate TextField1/2 in the Group object and TextField3/4 which are siblings to the Group and Subform objects -- not TextField3/4 which are wrapped in the Subform object.
Now let's say your data was as follows:
<data>
<TextField1>1</TextField1>
<TextField2>2</TextField2>
<Subform>
<TextField3>3</TextField3>
<TextField4>4</TextField4>
</Subform>
</data>
This would result in populating TextField1/2 in the Group and, as opposed to the first scenario, TextField3/4 which are wrapped in the Subform object.
This is a very simple example to prove a point. If you think about it a little, the implications -- especially concerning data binding -- are quite large. To help illustrate this further, I've attached a sample form with the hierarchy I described earlier as well as two data files: data1.xml is the first one I described in this post, while data2.xml is the second one. Try importing both into the form to see the differences in the results and then compare the object hierarchy in the Hierarchy palette with the nesting of the data nodes in the data files.
Finally, there's also the fact that subform instances can be created and deleted dynamically at runtime while groups cannot have instances. For dynamic forms, this is a big consideration.

Pros and Cons Between UNIX and Windows Servers

Hi,
Currently the business I work for runs SAP on UNIX, but there is talk of moving to Windows servers as there are more skills available in SQL.
It is our belief however, that UNIX servers are more 'stable' than Windows. We believe it would cost more in staff time if there was a transfer to Windows because of more system downtime, due to a larger amount of server updates.
I would like to know the experiences and opinions of' anyone who has made the switch from UNIX to Windows, or vice versa.
Has anyone considered moving to Windows and decided against it? What were the pros and cons?
II'm sure this is an issue that has been considered by many experts. I look forward to reading your responses.
Regards,
Luke

Thanks Michael, that thread is really useful and gives me some good information for my report.
I'm still interested in hearing more opinions on this. Is there anyone that has successfully fought off a proposed change to Windows from UNIX based on pros and cons, or vice versa? I want to hear both sides of the argument and have a really interesting, opinionated discussion in this thread.
Regards,
Luke

Anybody care to explain the pros and cons between chrome and safari?

Interested in knowing whether I need to put forth the effort to learn Chrome or just stay with Safari.

When I say taking it to the store I guess I need to share the entire story. When I bought this new system I transferred everything from my old computer to the new one but now I cannot bring up Adobe. Whenever something requires Adobe or Acrobat it says I must read and sign the user agreement. I contacted Apple Care and we worked the issed for quite some time and then as a last resort he said to download Chrome and we did and the Adobe came right up using this Chrome. Now whenever I'm working on something Chrome is trying to take over. Wile I don't do a lot of work in Adobe if I delete Chrome I won't be able to do any. That is why I am saying I guess I need to go to the store. Maybe they can correst my problem with the Adobe and get rid of Chrome. Like everbody seems to indicate it is best to be an Apple purest.

Pros and cons of personal messaging.

As learned from why users cannot send private messages to each other? personal messaging is currently disabled, but OTN staff apparently hopes to enable it in the next two weeks for users who are following each other (it probably means based on accepted Friend relationships).
For what it's worth, here is a list of Pro's and cons, including suggestions and alternatives collected from the mentioned discussion.
Unless there is anything wrong with my collection of cons, I cannot see or think of any pro.
Cons
Pros
A PM requires the prior acceptance of a Friend invitation to protect from spam and unsolicited messaging. It does not protect from unsolicited content.
OTN is as a safe and trusted environment and PM may attract or increase the risk of manipulation or fraudulent activity.
PM falls under the jurisdiction of OTN and can therefore be abused to challenge a victim to break the terms of use.
Rejecting or ignoring a Friend invitation could be considered personal and rude.
PM is not possible if someone does not qualify as a Friend, which can restrict personal messaging based on personal status and spoil the use of the feature.
PM may attract to solve technical problems on a private basis outside the public view and thereby defeat the purpose of the community.
Suggestions
Alternatives
Ability to enable or disable PM or Friend invitations on a general level in the user account preferences. A requester should receive a notice when such a feature has been disabled on a general basis.
Provide an optional email address field in the user profile, different from the login name, where people can find and expect personal contact information.

Dude, you list all those things as Cons, but many are purely subjective views of your own.
1.A PM requires the prior acceptance of a Friend invitation to protect from spam and unsolicited messaging. It does not protect from unsolicited content, though that is the same as any interaction on the internet. Whether you consider this a Con or a Pro is purely subjective. The need to be 'friended' first before being able to PM, provides a level of protection from unwanted PM's.
2.In rare cases the ability for people to PM may result in people manipulating others or using it for potentially fraudulent reason, however in most cases, like any other forum with PM features, it's just used by people who want to share something with a friend privately. The risk of manipulation and fraud is not proven to be greater through PM than through any other interactive media. The requirement to 'friend' before PMing allows people to only receive PM's from people they feel they are comfortable with, and if they don't like something they have the ability to 'unfriend' and prevent further contact.
3.If people feel they are being abused etc. via PM's they can raise their issue with the moderators/admin who will no doubt be able to look into the issue (or certainly admin should be able to)
4.Rejecting or ignoring a Friend invitation could be considered personal and rude by some people, but then anything people say on the forums can be taken by some to be rude. That's a personal subjective opinion, and the same anywhere on the ineternet. Just because a person believes it doesn't make it true. As taught in Buddhism, a person does not make you angry, the anger comes from within yourself.
5.Just as easily, the use of the forums could be 'spoiled' for people contantly receiving unsolicited PM's from people, if they didn't have to 'friend' them first. The restriction to just allow PM's for friends, allows individuals greater personal control over who they wish to be in contact with.
6.If people didn't have to 'friend' first then yes, some people would certainly try and use PM's to contact experts or others to try and get their technical issues solved off-forum, and even with the friend restriction, there's a possibility that some may still try that. The individual, however, has the choice to ignore such requests or reply to tell the person to post their issue on the forum, or maybe they're happy to provide free private support... that's a personal choice. I can't imagine most experts will be happy to just deal with people's issues off-forum (based on previous years on the forum where people have requested experts email addresses and be told to just post their issue on the forum). So, PM's could certainly 'attract' the idea that people can try and get private support, but those people are likely to be newbies and would most likely be told where to go.
However, I do agree that your suggestion would be a feasible option, allowing people to choose whether they wanted the friend and PM features enabled via a profile setting, though I do sense you are over-reacting (meant nicely) about people may consider it rude to have their friend request ignored/rejected. The ability to accept/reject/ignore friend requests does act as a kind of, more granular, method of enabling/disabling the PM feature... you get to choose who you want to have it enabled for.
As for the forum rules, that's a good point, and I hope moniquevdb-Oracle and her team will consider setting out the rules, not just for members, but also for the moderators, so that we can take on board any reports of abuse etc. and know whether they need raising. Certainly, a common rule on most forums in respect of PM's is that private messages are private and should not be posted on the public forum, and usually only the site administrators have access to look at such messages against individual profiles where a complaint has been raised.

What are the pros and cons of storing heavely used CFCs in the application scope?

I've been storing all the required CFCs for a site in the application scope. During onApplicationStart I do something like this application.objSomeCfc =CreateObject('component', 'com.someCfc').init().
Here is my reasoning.
Get the CFCs initialized once and stored in memory for better performance.
Using CreateObject several times on each page load can have a negative impact on performance.
Having one place to create application scoped CFCs makes it easier to manage code.
So is my thinking flawed? Are there any additional pros or cons for dealing with CFCs? Is there any docs, articles, blogs, videos, frameworks, ...... that I should check that may change my perspective on how I'm doing this?
Thanks

Your approach is fine, depending on how many and what type of CFCs you are talking about. If they are "singletons" - that is, only one instance of each CFC is needed to be in memory and can be reused/shared from multiple parts of your application - caching them in the application scope is common. Just make sure they are thread safe ("var" or local.* all your method variables).
You might consider taking advantage of a dependency injection framework, such as DI/1 (part of the FW/1 MVC framework), ColdSpring, or WireBox (a module of the ColdBox platform that can be used independently). They have mechanisms for handling and caching singletons. Then you wouldn't have to go to the application scope to get your CFC instances.

Pros and Cons of Application Isolation/Multiple server instances?

Hi. I'm setting a new server using ColdFusion Enterprise with Apache to migrate several web application from and old server with ColdFusion 7 server. I'm currently doing research regarding multiple server instances in order to have a separate server for production apps and another for development apps (see http://help.adobe.com/en_US/ColdFusion/10.0/Admin/WSc3ff6d0ea77859461172e0811cbf363c31-7ff 5.html and https://wikidocs.adobe.com/wiki/display/coldfusionen/Using+Multiple+Server+Instanceshttp:/ /). In addition, I'm also doing research regarding application isolation to have separate production application in separate servers. I'm trying to identify all pros and cons for both "Application Isolation" and "Multiple Server Instances" to make a decision on whether I will proceed in applying these techniques. I have found several links that talk about some of the advantages but have not been able to find anything regarding possible disadvantages. Have anyone in this forum has used any of the techniques, and can provide more information/experiences regarding the pros and cons?

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.

Boot Camp: Pro's and Con's? need some advice here

hey guys,
so im basicly quite newbish so ill try to keep things basic here and i advise you guys to do the same ;p
i have a few questions about the usage of bootcamp and ofcourse running windows with it.
i have wanted to buy office mac for a long time because i simply need the applications for my collage.
ive been thinking, because im kindoff a recriational gamer aswell and i just have a few somewhat classic windows games that id just like to play on the mac.
so prehaps it would be a wiser thing for me to just ignore the mac office package and just run xp or vista on bootcamp, it gives me the same applications and more. and ofcourse the possiblilty to run windows based games wich i kinda need aswell.
im just interested about hearing some pros and cons of the use of bootcamp and installing windows on my mac, will it increase the danger of attracting harmfull virusses, will it be heavy on my system memory? does it encouter errors alot? does it corrospond well with the existing hardware/software, will my system become somewhat instable? etc...
kindoff the basic pros and cons.
all of your feedback will be greatly appreciated.
thank you in advance,
greetings,
manuel

Manuel:
I am going to answer your question however please note that my answer is based on my experience and my experience only.
CONS
Takes up a portion of your primary HD of your laptop.
Requires a complete shutdown of OSx to get to Windows and vice versa.
Single tapping and double clicking does not work when using a trackpad on a laptop in Windows.
May have issues with running some windows based games.
Will attract viruses if user is not careful on the internet and opening attachments from unknown senders (I have never had a issue with this).
PROS
Runs windows natively and at near native speeds.
Has a wide range of Anti-Virus programs that do the job to keep viruses at bay.
Ability to run Windows based software just like one would on a windows PC.
With a 2GB system RAM, XP flies and Vista runs smoothly too.
Ability to boot back into OSx when needed or vice versa.
In short, boot camp has been a very pleasant experience for me. I use Windows daily as I need it for the type of work I am in and it has not let me down when running on a Boot Camp partition on an Intel Mac.

What are the pros and cons using Active Data Guard vs Data Guard?

My understanding is that Active Data Guard is an additional database option for Oracle 11gR2 Enterprise Edition. I need to know the pros and cons using Active Data Guard vs Data Guard in order to decide whether to get pay extra for the Active Data Guard.
Thanks for any help.

Hemant K Chitale wrote:
Before jumping in to Active Data Guard, one needs to evaluate :
a. Is there really a need to run queries on the Standby ? The Standby could / should be at a remote site so queries are "across the network". Depending on the nature of the queries and the volume of output, the "performance" of the queries may not seem to be the same.
b. If the database is not in Maximum Protection mode, the data "seen" at the standby may not be in "real-time" synch
c. Not all applications are truely read-only when querying. Some applications use "jobs" that write to tables when querying. Such would not work with Active DataGuard. (example : EBusiness Suite). There are very complicated ways of handling this -- and one needs to consider if the complications can be introduced and supported.
Over the network accessing standby read only is really not an good idea, I think no one will compare performance with primary and standby,
But some of them they want to validate data which are very critical, as it is matching with primary or not, Its an added advantage with ACTIVE DATAGUARD
Prior to that until unless stop MRP, open database and then we need to validate, So there is an interruption of recovery, I can say its also an advantage where there is no interruption of recovery.

What are the pros and cons re using an intel iMac vs MacPro with LP8?

I'm considering getting a new intel Mac in the near future (presuming a new MacPro will be released in the near future - maybe at the same time as Leopard). I compose largely for film and television and I am composing largely using a combination of loops, software instruments and some recorded live performance. I usually sync to a low res quicktime movie.
I do like the idea of a simple and uncluttered work environment with an iMac, added to which there's also a degree of portability with the iMac however the MacPro is obviously more powerful. I'm not sure how much the difference in power between the two computers would affect me.
Would I be compromising myself much if I went for the iMac over the MacPro? What are the pros and cons of the iMac vs the MacPro in relation to Logic Pro 8?

In the world large-scale music composition using samples, loops, etc (especially for film) your two biggest needs are RAM and HD speed/access. The imac looses big time in this department (as a single computer at least) as it can only be upgraded to 4gb ram, and only holds one internal HD, and also lacks any PCI expansion for DSP cards, audio interfaces, etc.
In generalyou want to separate your data vs applications as much as possible, to ensure both can be accessed quickly and easily by the computer. So its best to have your system software / applications on one internal HD, and your logic data (samples, audio recordings, loops) on another drive(s). You can do this with an iMac via USB, FW800, & FW400, but depending on how big your projects get, how many USB and FW drives / interfaces you use, and how much data you need to stream, you could overload the buss on the imac (not sure if it has multiple busses or not). Plus speed wise, internal SATA are much faster than external drives, and the mac pro with its 4 internal slots seems like a great choice for speed and flexibility.
However, if you dont find yourself doing large scale projects, then you might be better off going with an imac. We just purchased one for my father and it runs great! It blows the socks off of my Dual 2.5 G5 tower in terms of CPU speed! If you run into problems running things from the imac, you could always add a mac-mini down the road to stream sample libs, as a Logic node, etc, which seems to be a much more cost effective solution.
I hope this was helpful, but I probably just made the decision harder . In fact, if I were to start over today, I dont know if I'd go with a MacPro, or an iMac / mac mini combination. they both seem to have their advantages / disadvantages.
Best of luck!

Using CLOB data type - Pros and Cons

Dear Gurus,
We are designing a database that will be receiving comments from external data source. These comments are stored as CLOB in the external database. We found that only 1% of incoming data will be larger than 4000 characters and are now evaluating the Pros and Cons of storing only 4000 characters of incoming comments in VARCHAR2 data type or using CLOB data type.
Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;
- bind variables cannot be assigned CLOB value;
- dynamic SQL cannot use CLOBs;
- temp tables don't work very well with CLOBs;
- fuzzy logic search on CLOBs is ineffective;
- not all ODBC drivers support Oracle CLOBs
- UNION, MINUS, INTERSECT don't work with CLOBs
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?

Some of the concerns brought up during discussion were:
- having to store CLOBs in separate tablespace;They can be stored inline too. Depends on requirements.
- applications, such Toad require changing defaults settings to display CLOBs in the grid. Default value is not to display them;Toad is a developer tool so that shouldn't matter. What should matter is how you display the data to end users etc. but that will depend on the interface. Some can handle CLOBs and others not. Again, it depends on the requirements.
- applications that build web page with CLOBs will be struggling to fit 18 thousand chararcters of which 17 thousand are blank lines;Why would they struggle? 18,000 characters is only around 18k in file size, that's not that big to a web page.
- cashing CLOBs in memory will consume big chunk of data buffers which will affect performance;Who's caching them in memory? What are you planning on doing with these CLOBs? There's no real reason they should impact performance any more than anything else, but it depends on your requirements as to how you plan to use them.
- to manipulate CLOBs you need PL/SQL anonymous block or procedure;You can manipulate CLOBs in SQL too, using the DBMS_LOB package.
- bind variables cannot be assigned CLOB value;Are you sure?
- dynamic SQL cannot use CLOBs;Yes it can. 11g supports CLOBs for EXECUTE IMMEDIATE statements and pre 11g you can use the DBMS_SQL package with CLOB's split into a VARCHAR2S structure.
- temp tables don't work very well with CLOBs;What do you mean "don't work well"?
- fuzzy logic search on CLOBs is ineffective;Seems like you're pulling information from various sources without context. Again, it depends on your requirements as to how you are going to use the CLOB's
- not all ODBC drivers support Oracle CLOBs not all, but there are some. Again, it depends what you want to achieve.
- UNION, MINUS, INTERSECT don't work with CLOBsTrue.
I have not delt with CLOB data type in the past, so I am hoping to hear from you of any possible issues/hastles we may encounter?You may have more hassle if you "need" to accept more than 4000 characters and you are splitting it into seperate columns or rows, when a CLOB would do it easily.
It seems as though you are trying to find all the negative aspects of CLOBs and ignoring all the positive aspects, and also ignoring the negative aspects of not using CLOB's.
Without context you're assumptions are just that, assumptions, so nobody can tell you if it will be right or wrong to use them. CLOB's do have their uses, just as XMLTYPE's have their uses etc. If you're using them for the right reasons then great, but if you're ignoring them for the wrong reasons then you'll suffer.

Yes, you can package them together.
Now Cisco has a better way. Cisco UCS Manager provides two main advantages over past firmware provisioning:
• The capability to group multiple firmware components together in one package
• The capability to apply a firmware package to any compatible server in a single operation
Cisco UCS Manager provides an accurate, easier, faster, more flexible, and centralized solution for managing firmware across the entire hardware stack. Service profiles in Cisco UCS Manager abstract the physical hardware from its software properties. Service profiles allow administrators to associate any compatible firmware with any component of the hardware stack. Simply download the firmware versions needed from Cisco and then, within minutes, totally provision firmware on components within the server, fabric interconnect, and fabric extender based on required network, server, and storage policies per application and operating system.

Pro's and Con's if i run multiple host firmware packages in the single chassis

hi
i would like to know pro's and Con's if i run multiple host firmware packages in the single chassis.
Like if my UCS is running with firmware of 1.4.1m ( having backup of 1.3.1 and 1.1.1j) with 3 blades in one chassis
can i assign service-profiles having three different host firmware versions
Server1 - host firmware 1.1.1j-- win2k8
server2 -host firmware 1.4.1m -- RHEL 5.6 ( OS)
server -host firmware 1.3.1 -(esxi 4.0)
Thanks in advance ,please replay if can i go ahead with this . ASAP

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,
Adren

Hi 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.
