Need best practice: one application or many?

We have a database and are going to build GUI using ApEx
The question is:
should we create many applications - one for every task (or group of tasks / user roles)
or create one large application (hundreds of pages)
Why?

Greetings,
I don't know much about the subject.
But i can tell you two things.
First you can create groups inside an applications so even having hundreds of pages you can still have them seperated by groups.
Second in a large applications composed by several applications you can make a common login for all so you only need to login once. I have seen a thread about thsi recently.
My opinion?
One application is best...
Because in a GUI you probably will have a lot of Javascript to make things smooth in the client side.
Also Javascript code can and SHOULD be kept apart from the application, you should just link the file to the application template. I recomend prototype/scriptaculous for this because they are already used by APEX and are excelent with many examples in the web.
Don't forget to assign points to those who help you! (Mark the thread Helpful/Correct)

Best Regards

Which version are you setting up and what are the requirements? IF you are discussing the use of NIC bonding for high availability beginning in 11.2.0.2 there is a concept of "High Availability IP" of HAIP as discussed in the pre-installation chapters,
http://docs.oracle.com/cd/E11882_01/install.112/e22489/prelinux.htm, section 2.7.1 Network Hardware Requirements.
In essence, using HAIP eliminates the need to use NIC bonding to provide for redundancy.

Swing best practice - private modifier vs. many parameters

Dear Experts,
I have a comboBox that has a customized editor and has KeyListener that responds to several keyPressed and keyTyped. The comboBox is used in two different JFrame, say JFrame frmA and JFrame frmB.
Since the KeyListener changes the state of 8 other components in frmA, I have two options:
Option 1:
- Coding the comboBox in separate class and pass all components as parameters. I will have around 10 parameters, but the components can be made private to frmA or frmB.
Option 2:
- Coding the comboBox in separate class and pass the instance of the caller (frmA or frmB), so that the comboBox can change the state of the other components in frmA or frmB according to its caller. However, the components must not be private and should be able to be accessed by the comboBox class.
My questions:
1. I have not implemented option 2, so that I have not proved that it will work. Will it work?
2. Which option will be more efficient and require less cpu time? If it is the same, which option is the best practice?
3. Is there any other option that is better than these two options?
Thanks for your advice,
Patrick

Option 2:
- Coding the comboBox in separate class and pass the instance of the caller (frmA or frmB), so that the comboBox can change the state of the other components in frmA or frmB according to its caller. However, the components must not be private and should be able to be accessed by the comboBox class.
My questions:
1. I have not implemented option 2, so that I have not proved that it will work. Will it work?It doesn't stand in the long run. Doing so couples your specific ComboBox classes to all widgets that react to the ComboBox changes. If you happen to add a new button is either JFrame that should also be affected by the combo-box selection, you'll have to modify, and re-test, the ComboBox code. Moreover, if a new button was needed in one the JFrame but not the other, you'd have to introduce a special case in your combobox code.
Instead of the ComboBox's listeners invoke methods on each piloted widget, have them invoke one method (+selectionChanged(...)+) on these widget's common parent (not necessarily a graphical container, but an object that has (maybe indirect) references to each of the dependant widgets).
2. Which option will be more efficient and require less cpu time?I wouldn't mind.
In the graphical layer of an application, and unless the graphcial representation performs computations on the bitmap, any action is normally much quicker than business logic computation. Any counter-example is likely to be a bug in the UI implementation (such as, not observing Swing's threading rules), or a severe flaw in the design 'such as, having a hierrachy of several hunderd JComponents,...). Swing widgets are pretty reactive to genuine calls such as setEnabled(), setBackground(), setText(),...
If it is the same, which option is the best practice?Neither. Hardcoding relationships between widgets may be OK within a single, and single-purpose, form.
But if you want to code a reusable component thoug, design it for reuse (that is, the less it knows about how which context it is used in, the more contexts it can be used in).
In general, widgets that know each-other involve a quadratic number of references that accordingly impacts the code readability (and bug rate). This is the primary reason for introducing a Mediator pattern (of which my reply to 1 above is a degenerate form).
3. Is there any other option that is better than these two options?Yes. Look into the [+Mediator+|http://en.wikipedia.org/wiki/Mediator_pattern] pattern (the Wikipedia page is not compelling, but you'll easily find lots of resources on the Web).

Best practices for subcriptions of many servers

Thinking of monitoring free space on my servers. Servers are 2003,2008,2012 (plus R2). Basing on
http://fehse.ca/2013/07/disk-space-monitoringcommon-practices/ - need to make three monitors for each version of server. So, the best practice is to create there groups based on version
condition. But we have many specialized servers (BizTalk, CRM, different application servers etc.) and want alert send to application admins. How can I implement such taks without creating a buch of groups based on application and override each monitor to
each group?

If you have multiple different teams, you will most likely need multiple different SCOM groups to organize your notifications and configure overrides against. You could limit the number of groups you have to create by using the same group for both
the override and the notification to the app team. For example, if you are looking to customize thresholds for the Biztalk servers, you would create a SCOM group and add the various logical disk objects to that group. When you create your threshold
override, you will target that group of disk objects. When you create your notification, you will scope the notification to the logical disk space monitor and this group of disk objects. Beyond this there isn't much you can do to keep from creating
a bunch of groups. You may actually have multiple groups for the Biztalk team even, if they are utilizing multiple os'es for their servers because you should not combine disks from different os versions into the same group as your overrides will not
work properly.

Best practice for application module for scalability

if i compare application module with forms 6i runtime session.(correct me if i wrong)
In forms 6i, we create for single form for purchase entry. in which we select table like po , po_item, item_master, customer master
also single form for sales entry. in which we select table like sales , sales_item, item_master, customer master, po , po_item
So my question is. in jdeveloper , we planning to make separate jsp page and applicaiton module for purchase entry,
separare jsp page and application module for sales.
is it ok.
or
what is the best practice in this senario.?? ( or in scalability senario)
if i made one single application module for whole application (let say 300 entity's(tables)) will performance of my app server degrade.

Looking for best practice on application scope beans

Hey â€“ a portal newbie here. Iâ€™ve got some application scope beans that need to be initialized on startup. First thought was to create a servlet that would set the bean. Then I saw the GlobalApp setting, but I think that looks like it is more session scope than applicationâ€¦ Looking to be corrected here if I am wrong.
Is there a place where these type of things traditionally happen? Read only, so no cluster worries (I think) Using WLP 8.1 SP4 and looking for best practices. Thanks for the help!

To support "code sharing" you need an integrated source code control system. Several options are out there but CVS (https://www.cvshome.org/) is a nice choice, and it's completely free and it runs on Windows, Linux, and most UNIX variants.
Your next decision is on IDE and application server. These are usually from a single "source". For instance, you can choose Oracle's JDeveloper and Deploy to Oracle Application Server; or go with free NetBeans IDE and Jakarta Tomcat; or IBM's WebSphere and their application server. Selection of IDE and AppServer will likely result in heated debates.

Captivate 4.0 - Need best practice tips on panning, templates, resolution, etc.

Hi all,
Been searching all over in case someone has already published Best Practices for Captivate 4.0 (particularly the new/enhanced features), but coming up empty. My client's in house graphics person has been tasked with creating a template for us to use for a number of software simulations. He's running in to these challenges:
- Our SWF needs to be 800 x 600 and he created the template for this size, but the app won't fit.
- He's found the panning feature to produce very choppy, disappointing results. Tips?
- His suggestion is we capture at 1024 x 768, then resize to 800 x 600, then copy/paste the slides into his 800 x 600 template. Would we be better off recreating the template at 1024 x 768 and not resizing until the final output is generated for each tutorial? His concern is that our template will then become larger, making it harder for us to send back and forth as changes are made, etc.
Any other suggestions for how to deal with the resolution issue, how best to take advantage of templates, etc.?
Thanks,

Hi there
In my own opinion, Panning is a nice attempt, but just doesn't cut the mustard. It's nowhere near as good as the panning one sees with Camtasia Studio.
I might suggest combining Camtasia with Captivate for the ultimate development set. There are aspects Captivate shines in when compared with Camtasia, and there are aspects Camtasia shines in when compared with Captivate. So I say if you can afford it, go for it!
Now I know that both packages are sort of pricey and not everyone can afford both. In that case you might want to try Jing, which is free to use. I've not looked very deeply at it, but it may offer some of what Camtasia does. You could then use that for your panning and enhance Captivate that way.
Cheers... Rick

Best practice for application help for a custom screen?

Hi,
The system is Netweaver 7.0 SP 15 with e-recruiting .
We have some custom SAP GUI transactions and have written Word documents with screen prints and explanations. I would like to make the procedure document accessible from the custom transaction or at least provide custom help text that includes a link to the full documents.
Can anyone help me out with options and best practices for providing customized application help for custom SAP GUI transactions?
Thanks,
Margaret

Hello Margaret,
sorry I though you might be still in a design or proof of concept phase where the decision for the technology is still adjustable.
If the implementation is already done things change of course. The standard in-system documentation is surely not fitting your needs as including screenshots won't work well.
I would solve the task the following way:
I'd make a web or pdf document out of the word document and put it on a web ressource - as you run e-recruiting you have probably the possibility for that.
I would then just put a button into the transaction an open a web container to show the document.
I am not sure if this solution really qualifies as "best practise" but SAP does the same if you call the Help for application in the help menue. This is implemented in function module SAPGUIHC_OPEN_HELP_CENTER. I'd just copy it, throw out what I do not need and hard code the url to call.
Perhaps someone could offer a better solution but I think this works a t least without exxagerated costs.
Kind Regards
Roman

Building a best practice web application using ColdFusion and Jave EE

I've been tasked with rewriting a software using ColdFusion. I cannot seem to find a lot of information on best practice development in ColdFusion. I am an experience Java developer who has never used ColdFusion before. I want to build this application using a synergy of ColdFusion and Java EE technologies. Can someone recommend me a book that outlines how to developer in ColdFusion? Ideally this book assumes the reader is an experienced developer with no exposure to ColdFusion. Ideally the methods outlined in the book are still "best practice" methods.

I am a building a new web application using JSF and AJAX.
Requirement is I need to use IBM version of DOJO and JSF but I need to develop the whole application using Eclipse 3.3,2 and Tomcat 5.5.
With IBM version of DOJO and JSF, will Eclipse and Tomcat help to speed up the development or do you suggest me to go for Rational Application Developer and WebSphere Application Server.
If I need to go with RAD and WAS, then I am new to RAD and WAS, is it easy to use RAD and WAS for this kind of application and implement web applicaiton fast.
Any feedback will be great help.Those don't sound like requirements of the system to me. They sound more like someone wants to improve their CV/resume
From what I've read recently, if it's just fast you want, look at Ruby on Rails

Need best practice when accessing an ucm content after being transferred.

Hi All,
I have a business requirement where I need to auto-transfer the content to another UCM when this content expires in the source UCM.
This content needs to be deleted after it spends a certain duration in the target UCM.
Can anybody advise me the best practice to do this in the Oracle UCM?
I have set up an expiration date and trying to auto Replicate the content to the target UCM once the content reaches the expiration date.
I am not aware of the best practice to access the content when it is in the target UCM?
Any help in this case would be greatly appreciated.

SR,
Unfortunately temp tables are the way to go. In Apex we call them collections (not the same as PL/SQL collections) and there's an API for working with them. In other words, the majority of the leg work has already been done for you. You don't have to create the tables or worry about tying data to different sessions. Start you learning here:

Need Best Practice - Apex, multiple schemas, security model

We have an oracle database which contains
a) named database users with no objects
b) several schemas with data tables:
sales
marketing
accounting
We need to build GUI for tables in these schemas,
every database users should belong to a group, each user group should have access to several (not all) GUI pages.
1) Is it possible and is it recommended (if not - why?) to create ONE workspace and ONE application inside it to have access to ALL tables in ALL schemas listed with user groups level security?
How to do it properly?
Some link to documentation?
2) Which security model (apex users, database users,..) to choose and why? please recommend some links to comparison...

Hi Marcus,
Our developers like to see all the tables for a single custom application in its own diagram no matter where they come from and the DBA's don't want to wade through several thousand tables to find the handful we need nor have to duplicate table definitions in multiple models. In >Designer we have been doing that with Application Folders.There are no application folders in data Modeler. You can use subviews to define your subject areas. Subview is crated for each application (folder) during import form Designer repository.

Expert opinion needed: Best practices to handle huge rowsets on UI

Hi All,
I need to know what are the best practices from Oracle to handle huge rowsets on the UI.
My ADF 11g app is a custom monitoring cum reporting tool for a highly active integration solution.
The user can give me a selection criteria say show transactions between yesterday and tomorrow and our highly active transactional system may return upto 5000 records.
I am showing these records in a tabular format and since pagination is not there we are depending on auto scrolling which is kind of slow.
So please advice me what options come to your minds for showing/informing users of such rowsets.
I am aware ideally UI should not have more that a couple hundred records but our use case does not adhere to that.
Thanks

since pagination is not there I'm not sure what you mean by this, the ADF Faces table does pagination when you scroll - so if your business service has 5000 records but the rows property of your table is set to 25 - you'll just fetch 25 records to the client.
When you scroll down you'll fetch another 25.
This type of thing is automated for ADF BC data controls - and you can control the range set.
We also generate the code needed for EJB Facades to do this with JPAs.
If you have your own Java class as a data source you'll need to implement this pagination on the business service side see exapmle 37 here: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html
