Best Practice for Portal Patches and effort estimation

Hi ,
One of our client is applying the following patches
1. ECC 6.0 SP15(currently SP14)
2. ESS MSS SP15(currently SP14 with some level of functional customization )
3. EP 7 SP18(currently SP14)
We would like to kwow the best practice for applying portal patches and the effort estimation for redoing the portal devt on the new patch.
o   What is the overall level of effort with applying Portal patches?
o   How are all the changes to SAP objects handle? Do they have to be
     manually re-entered?
o What is the impact of having a single NWDI instance across the
    Portal Landscape during the Patch process?
Regards,
Revathi Raju.

Hi Revathi,
o What is the overall level of effort with applying Portal patches?
overall effort to apply the patch is apprx 1/2-1 days for NW7 system. This is exclude the patch files download because it's based on your download speed.
o How are all the changes to SAP objects handle? Do they have to be
manually re-entered?
Depending on your customization. Normally it wont effect if you created the customzation application apart from SAP standard application
o What is the impact of having a single NWDI instance across the
Portal Landscape during the Patch process?
Any change that related to NWDI, you might be need to re-deployed from NWDI itself.
Thanks

Best Practices for BI, ADF and Oracle Forms installations on Weblogic

Hi, I'm researching options on upgrading to Oracle 11g Middleware. My company currently has Oracle Forms 10g running on Oracle Application Server.
We are interested in using Oracle Forms 11g, ADF and Jdeveloper, and Business Intelligence with Oracle's Weblogic 10.3.5.
Is there any whitepapers or documentation on best practices for installing alll of these components together?
For instance, can ADF ( with JSF 2.x ) be installed in the same domain as Oracle Forms 11g but use different managed servers?
Will Business Intelligence need to be in a seperate Oracle Home with it's own weblogic installation? I spend a lot of time trying to get the JSF upgraded to 2.x in the Business Intelligence installation and could not get it to work.
I know it's a pretty broad question but thank you for any direction on this.

Thanx for the reply! I read through the documents and they are very good at explaining how to install the different components individually. I still can't find much on installing them together. I hope it's not just going to be a trial and error thing.
So far I've installed done the following successfully:
Installed 10.3.5 weblogic
Forms and Reports 11g on top of 10.3.5
I've created an additional managed server for our ADF applications.
My next step is upgrading the JSF to 2.x. I would have to stage patches 12917525 and 12979653. I'm afraid it will break the forms and reports though. Any ideas?

Best Practices for Using Photoshop (and Computing in General)

I've been seeing some threads that lead me to realize that not everyone knows the best practices for doing Photoshop on a computer, and in doing conscientious computing in general. I thought it might be a good idea for those of us with some exprience to contribute and discuss best practices for making the Photoshop and computing experience more reliable and enjoyable.
It'd be great if everyone would contribute their ideas, and especially their personal experience.
Here are some of my thoughts on data integrity (this shouldn't be the only subject of this thread):
Consider paying more for good hardware. Computers have almost become commodities, and price shopping abounds, but there are some areas where spending a few dollars more can be beneficial. For example, the difference in price between a top-of-the-line high performance enterprise class hard drive and the cheapest model around with, say, a 1 TB capacity is less than a hundred bucks! Disk drives do fail! They're not all created equal. What would it cost you in aggravation and time to lose your data? Imagine it happening at the worst possible time, because that's exactly when failures occur.
Use an Uninterruptable Power Supply (UPS). Unexpected power outages are TERRIBLE for both computer software and hardware. Lost files and burned out hardware are a possibility. A UPS that will power the computer and monitor can be found at the local high tech store and doesn't cost much. The modern ones will even communicate with the computer via USB to perform an orderly shutdown if the power failure goes on too long for the batteries to keep going. Again, how much is it worth to you to have a computer outage and loss of data?
Work locally, copy files elsewhere. Photoshop likes to be run on files on the local hard drive(s). If you are working in an environment where you have networking, rather than opening a file right off the network, then saving it back there, consider copying the file to your local hard drive then working on it there. This way an unexpected network outage or error won't cause you to lose work.
Never save over your original files. You may have a library of original images you have captured with your camera or created. Sometimes these are in formats that can be re-saved. If you're going to work on one of those files (e.g., to prepare it for some use, such as printing), and it's a file type that can be overwritten (e.g., JPEG), as soon as you open the file save the document in another location, e.g., in Photoshop .psd format.
Save your master files in several places. While you are working in Photoshop, especially if you've done a lot of work on one document, remember to save your work regularly, and you may want to save it in several different places (or copy the file after you have saved it to a backup folder, or save it in a version management system). Things can go wrong and it's nice to be able to go back to a prior saved version without losing too much work.
Make Backups. Back up your computer files, including your Photoshop work, ideally to external media. Windows now ships with a quite good backup system, and external USB drives with surprisingly high capacity (e.g., Western Digital MyBook) are very inexpensive. The external drives aren't that fast, but a backup you've set up to run late at night can finish by morning, and if/when you have a failure or loss of data. And if you're really concerned with backup integrity, you can unplug an external drive and take it to another location.
This stuff is kind of "motherhood and apple pie" but it's worth getting the word out I think.
Your ideas?

Our power outages here are usually only a few seconds; this should give my server about 20 or 25 minutes run-time.
I'm setting up the PowerChute software now to shut down the computer when 5 minutes of power is left. The load with the monitor sleeping is 171 watts.
This has surge protection and other nice features as well.

Best practice for OSB, OER and OSR

Hi,
I would like to know what are the best practices for using OSB, OER and OSR together in a run-time environment for a simple WSDL service.
From how I see it:
1) Create service-definition in OER
2) Create proxy and business service in OSB
3) Use harvester to harvest the proxy and business services in OER
4) Use Exchange Utility to publish the proxy service to OSR
Then the client and discover the proxy service and use OSB for invoking the operations from service.
Kindly correct me where I am wrong.
Some questions:
1) Do we ever publish business service to OSR? Or is it only meant for proxy services?
2) Is synching of OSB and OSR only meant when we are not using OER?
Looking forward...

Hi Anuj,
Thanks for the links, they have been helpful.
I understand now that OSR is only meant to contain only Proxy services. The synch facility is between OSR and OSB so that in case when you are not using OER, you can publish Proxy services to OSR from OSB. What I didn't understand was why there was a option to publish a Proxy service back to OSB and why it ended up as a Business service. From the link you provided, it mentioned that this case is for multi-domain OSBs, where one OSB wants to use the other OSB's service. It is clear now.
Some more questions:
1) In the design-time, in OER no Endpoints are generated for Proxy services. Then how do we publish our design-time services to OSR for testing purposes? What is the correct way of doing this?
Thanks,
Umar

Best practice for Error logging and alert emails

I have SQL Server 2012 SSIS. I have Excel files that are imported with Exel Source and OLE DB Destination. Scheduled Jobs runs every night SSIS packages.
I'm looking for advice that what is best practice for production environment.Requirements are followings:
1) If error occurs with tasks, email is sent to admin
2) If error occurs with tasks, we have log in flat file or DB
Kenny_I

Are you asking about difference b/w using standard logging and event handlers? I prefer latter as using standard logging will not always data in the way in which we desire. So we've developed a framework to add necessary functionalities inside event handlers
and log required data in the required format to a set of tables that we maintain internally.

Best Practice for Multiple iTunes and One Account?

My wife and I share our account for our iPhone Applications and Songs in iTunes.
Can someone point me to a topic that covers a best practice for multiple iTunes syncing?
I travel a lot and keep my iPhone synced to my Macbook Pro while she uses the workstation at home to sync to. We keep the addresses and contacts and calendars synced through MobileMe, however, I'm trying to find the best way of pushing applications and songs I've bought over to the other PC so they're still around while I'm traveling for her to sync with.
Thoughts?

Hi Steve,
Might be trying for solution for a long time, If i understood your question clear let me clarify you few points.
You are trying to access the bex query which is designed with the exit's in the background based on the logic and trying to call the entire dimensions and key-figures in a single connection. Then you are trying to map those data in the charts.
Steve, try to make more connections based upon the logic and split them. use the same query but split them by sales per customer group, sales per day, sales per week by making three different connections and try. You can merge the prompts from all connections.
Hope this Helps!!!
Sorry if i misunderstood your question.

Best practices for handling elements and symbols (including preloading)

I am trying to learn Edge Animate and I have not seen enough animations to know how this is typically handled and I searched the forum and have not found an answer either.
If you have many different elements and symbols for a project, what is the best practice for having them appear, disappear, etc. on the timeline? I ask this question not only from a performance based perspective, but also keeping in mind the idea of preloading. This is a 2 part question:
Part 1: Using elements and symbols later in the timeline:
Since artwork is always imported directly to the stage in an "always on" status, should we place a visibility OFF on every item until we need it?
or should they be opacity 0 until I need them?
or should they be set to visibility hidden until I need them?
Which of these is the best option if you don't want the element / symbol visible until later in the timeline? Does it matter?
Part 2: Impact on page loading
Does the above question have any impact upon page loading speed
or is this something handled in preloading?
or do you need to make a special preloader?
Thanks for the help.

Hi, escargo-
Good questions!
Part 1: Using elements and symbols later in the timeline:
Since artwork is always imported directly to the stage in an "always on" status, should we place a visibility OFF on every item until we need it?
or should they be opacity 0 until I need them?
or should they be set to visibility hidden until I need them?
Which of these is the best option if you don't want the element / symbol visible until later in the timeline? Does it matter?
I would recommend that you set your visibility to "off" instead of simply changing the opacity. The reason I suggest this is that when your visibility is set to off, your object's hit points also disappear. If you have any type of interactivity, having the object still visible but with 0 opacity will interfere with anything you have underneath it in the display order.
Part 2: Impact on page loading
Does the above question have any impact upon page loading speed
or is this something handled in preloading?
or do you need to make a special preloader?
Thanks for the help.
No, none of this has any impact on page load. As you already noticed, all of the assets of your project will load before it displays. If you want only part of your composition to load, you may want to do what we call a multi-composition project. There's a sample of that in the Edge Animate API in the Advanced section, and plenty of posts in the forums (and one in the team's blog) explaining how to do that.

Best practices for graphic divs and classes

Nice day webmates, I am looking for good and simple tutorials
on creating divs with attractive looks, such as rounded corners,
own-customized (made in FW), displaying shadows... so I can type
content inside them... what are the best practices for this ?
thanks a lot in advance...

Bad example. When you increase text size that site becomes
unusable.
Best practice, don't use absolutely positioned divisions (aka
layers).

What are the best practices for Database management and performance tuning?

Hello,
I want to ensure that I am using the best practices for managing and maintaining our Database.
Is there any documentation out there that outlines how to maintain and ensure top performance out of our database?
Thank you!
John Sefton

I appreciate the responses, however this is not the information I am looking for.
I am specificaly looking for best practices invloving the managment and performance tuning.
Example: are their tools that I can install that will monitor the size and response time of the database and alert me if there is degradation in performance?
Are there specific periodic activities I should be doing to garuntee that my database will continue to function that way it is supposed to?
Or is this a fire and forget solution that does not need this attention?

Best practice for backing up and restoring forms

Greetings, I would like to pose a question to the forum and understand how many of you, if at all, "backup" your interactive forms so that in the event one or multple become corrupt, you have a method to recover the forms.
We recently experienced such a scenario in which the forms we developed in ABAP, and access through our portal, had become corrupt. What would happen to us when we attempted to access the form via the portal would be a SOAP error. SOAP errors, I understand, can happen for various reasons but prior to the incident, our forms were working just fine. We attempted to retrace our steps to identify the cause of the problem but found we could not replicate the issue. Through analysis of the forms, we identified the corruption in the master page and found that if we copied the sections of the form that were not corrupt to a new master page, the form would work properly again. Our thought is that this can not be the only method to recover from an incident like this and would like to know if others have experienced or have practices in place that would minimize the impact.
We asked SAP support whether or not there was a method to back up Interactive forms and the simple answer we received was to download the XML file from txn SFP. Can others relate to this strategy as a proper "backup" method or do other best practices exist that would be more ideal??
Thank you in advance!

I had many difficulties with this kind of errors like 2 years ago. Of course it was getting better with every patch level, and with LCD 8, LCD 8.1 etc.I don´t have any problems with the newest solution, but remember the feelings. I had to throw away a three days work once because of this "errors". But the solution is easy:
- use the versioning like you do in your ABAP development, that works ok
- if you would like to have an extra backup, copy the form into a backup, I mean with name like Z_YOURNAME_BCK_1
- if you still feel that is not enough, you can always set your forms to be dynamic, what makes the ADS webservice to change the way the forms are constructed (now it will have a internal structure, you can check this out, if you open a dynamic form in LCD outside SAP, it works like a charm, if you open just a printform, it asks for an import, which does not have anything in common with the template earlier). And you can backup every form you generate with these settings. If a problem appears, you can always open this outside SAP in LCD, copy the hierarchy and paste it into your SAP window with LCD development.
Hope that helps.

Wireless Design - Best Practices for Data, Voice, and LBS

Hi,
I am currently in the process of designing a WLAN for a new hospital and I am getting some push back from my sales team. The requirements of the WLAN are data, voice, and location based services (RFID for medical equipment) ... needs to be 2.4 GHz for Guest and some apps/clients but primarily 5 GHz for most of the clients ... lastly needs to be N compatible for future use.
So, I did a predictive design with 1252's on the perimeter with 2.4 and 5 GHz patch antennas and 1142's in the middle to fill gaps ... I also scoped out 2 5508 for redundancy .... total design with -65 at my edges was 169. However, this is getting push back because of several cost issues ....
1. The bundle that Cisco offers for 5 100 AP license 5508 WLC is cheaper than buying 2 250 AP licenses WLC's ... which doesn't make any sense to me because I think 5 devices is over kill
2. The sales engineer is concerned about the power issues with the 1252's ... customer would rather not use power injectors ... and although they would have 6500's at there core ... they would only have basic switches in their IDF's so I wasn't sure which POE Switches would be able to handle 1252 but cost was an issue there as well
So, for my understanding when you are doing a WLAN design for LBS it's always best to have APs or antennas on the perimeter for better triangulation ... it makes more sense to me to do that with patch instead of Omni's ... however my sales engineer wants to use all 1142's ... so my question is what are the pro and cons behind using all Omni's or using Patch and Omni's?
Furthermore, if anyone has any documentation supporting why I would not use all Omni's that would be great because all the articles I have read on LBS just state that placement of APs is critical but doesn't give no specifics on whether it's a good practice to place them on the perimeter using a specific type of antenna or what.
Thanks in advance for you help and any ideas about this design!!!

1. The 5508 is expensive because it's alot faster than the 4400 plus there are some features exclusive to the 5508 such as OfficeExtend. As the old network design adage goes: Your design can be done correctly, cheap or fast. Choose two.
2. The 1250 requires 19.5w of power to enable FULL MCS rates to both radios. Only the 3560E, 3750E or the Sup720 is capable of supporting that. Upgrading the IOS of the 1250 to 12.4(10b)JDA3 will allow the AP to operate both radios at 15.4w BUT at a lower MCS rates. Correct placement of the AP and the correct use of the antennaes will also help in the signal distribution.
3. Patch antennaes are mostly directional. The 1140 is onmi-directional BUT the signal strength is not as powrful as the 1250 at full power. The AIR-ANT2451NV is an omni-directional patch designed for the 1250.

Best practices for JavaFX architecture and patterns?

Hi,
I want to write reusable, easy to maintain JavaFX code for a larger UI project and wonder what are the best practices doing so.
1) Are there preferred UI patterns? MVC, MVP, Presentation Model, ...?
2) Does it make sense to use FXML to separate View from Logic? Or should I use 2-3 Java classes instead (one for View, one for Logic, one for Domain Model, depending on the pattern)
3) How to organize all the views? Should I use Dependency Injection? Or Singletons for each view? Spring or Guice framework, if at all?
Currently I use singletons for most views, so that I can use them from anywhere in my application. If a window is closed and opened again, I use the same instance for that, which still resists in memory.
For patterns, I try to lean on Presentation Model, since this is what I know from Flex development: Having a View layer, which contains all the UI stuff and an abstract view layer, which holds properties, that describe the View, e.g. submitButtonDisabledProperty. The View knows the abstract layer (Presentation Model), but not vice versa and the UI elements are bound to its properties.
I am unsure if this is appropriate for JavaFX, too (for Flex or Silverlight it is).
What are your recommendations / experiences for large UI projects?

You are correct that in 'pure' MVP the View should know as little about it's presenter implementation as possible. The view should just notify one or more 'listeners' that something has happened.
You can use event listeners for this, but I would highly recommend not exposing your Control-specific GUI events and instead create your own. So for example, don't expose ActionEvent or MouseEvent as these expose too much detail about your View's implementation, instead create 'semantic' events, so you might have something like 'sayHelloRequested' or 'printOptionSelected' (whatever naming system you want). This hides how the option is implemented, so you might have a 'print' button, a 'print' menu option, a CTRL+P print shortcut, or a double tap anywhere on your screen to print. The listener knows only that the view thinks 'print was requested by the user' - decoupling achieved.
Once you start doing this however you end up with an explosion of event listener interfaces. So say a view has 10 callbacks it wants to notify about, then you end up with 10 interfaces, and if you're being really pure you also end up with 10 'Event' beans (or DTOs) to encapsulate the details of that event. It starts to get ungainly even for a semi-purist like me. So the logical progression from there is usually just to define all 10 callbacks in one interface and call it something like MyViewListener.
There are two common ways to implement listeners, the traditional way is to allow an arbitrary number of listeners to be added. Whereas another option is to allow only a single listener to be added. In JFX you will notice that Button for example has a setOnAction() method not a addOnAction() method - it allows a single event handler only and let's face it this is generally fine in 95% of cases. For the remaining 5% you can just write your own aggregate event handler that dispatches the event to multiple listeners.
So if we go down the road of single event listeners, using an interface for all of the callbacks and not bothering with full 'Event' objects, you end up with something like this:
public interface MyViewListener {
    void printRequested();
    void doSomething(int someParam);
    void doSomethingElse(String someOtherParam);
}And if you look closely at the 'Purist' option in my MVP pattern where I define interfaces for everything, then you will see that this is pretty much the exact interface I've created for the 'Presenter'. You could just as easily rename this interface to MyViewListener in this pattern and have the same outcome.
So to wrap all that up, yes, the Presenter should be decoupled and I highly favour the 'purist' option in my blog and would definitely use it if FXML didn't dictate a impure design pattern (there are some ongoing discussions about this on the OpenJFX discussion group). And, yes, my 'purist' option could be even more pure if you went for the full-blown event callback model and if you go down that road you will have an extremely clean architecture but also an extremely large code-base - totally your call whether it's worth it.
It's also worth remembering in all this, that there are a lot of people from a lot of different backgrounds using JFX and some people hate (passionately) even my semi-pure option - especially those coming from other, less heavy-weight languages. They just don't get why you wouldn't build it all into one class and reduce the overheads. So what you have in my blog is my thoughts on it, other people will most definitely differ. I'm a big fan of developer's choice, and that's why I did the smorgasboard approach even though I personally would never use some of those implementations.
Also this video on GWT is an awesome reference on GUI design patterns: http://www.youtube.com/watch?v=PDuhR18-EdM
JFX Flow draws a lot from GWT as I think it is a very clean architecture (just such a shame that they put all that effort into hiding the horrid, sordid mess that is the web+html+css, instead of making something proper, like JFX).
Hope that helps,
