Seeking advice on best technology for application

We are in the process of evaluating the best technology to use to bring over some of our applications that were written in Lotus Domino to the SAP Enterprise Portal.
From what I've personally seen and heard (and worked with) it sounds like Web Dynpro is the way to go but I wanted to see what others' experiences may have been if they were in a similar situation.
To give an idea of application #1 to be converted it is an online approval system- mainly used for Purchase Requisitions but can be any sort of lineitem(s) that need approval from a list of approvers. This will NOT initially integrate with our R/3 system as we do not do Purchase reqs in there- the buyer manually creates a PO in R/3 and that will remain at least for a time after the new process goes live.
The application is made up of ~40 forms and needs to be able to do the following:
1. Display a users' list of their requisitions on the home page
2. Allow a user to create a new requisition (link to req needs to be emailed to approver #1 on the list). User will input data via drop downs for ship to address and will enter supplier info, requisitioner info, and info on what is being purchased. We want to get the user information from the UME and pre-populate some requisitioner info but allow the user to then change it if doing a req for another person. We want to be able, at some point, to allow the part number to do a lookup in R/3 to obtain a part description.
3. Allow an approver, once they receive the email to approve or deny the req then move it on to next approver.
4. Eventually a buyer will get the req in email and will have to approve or deny the req.
So- at a minimum we are looking at a good number of forms, a fairly extensive data dictionary, and the implementation of workflow. I want to try to determine what technology- web dynpro, J2EE, or some other would be the best way to approach this in the portal. As of now there is a single developer (myself) assigned to this task. An idea of how long a project like this would take in each technology (even a very rough one) would be helpful as well. If you need more information from me to provide me some information feel free to request it- just trying to get my management an idea of what direction we should go in and how long to expect the project to take as this would be portal programming project #1 for me.
Thanks!

Hello Dana,
taking a look at Lotus Domino and the description of your application I see that you need a persistence layer (to store the information that you formerly use Notes documents for), screens (Notes Forms) as well as workflow functionality (Notes document routing and document state processing). The business logic can be transferred to Java classes (equivalent to Notes Agents) or EJBs. To me it looks like a perfect case for a composite application.
With SAP NetWeaver, you may use the following technology:
- CAF Guided Procedures for workflow (e.g. based on the Java Workflow Engine http://help.sap.com/saphelp_nw04s/helpdata/en/94/064e7a2f8a4f10a488f098febd84c4/frameset.htm)
- Java dictionary project for persistence and business logic
- Screen design can be done with Visual Composer (free-style) or more extensible with WebDynpro.
When doing so, the guided procedures keep control of the screen flow and multi-user guidance (workflow). The screens designed by VC or WD are then linked to guided procedures as callable objects.
Don't forget to use NWDI

Michael

Seeking advice on Best Practices for XML Storage Options - XMLTYPE

Sparc64
11.2.0.2
During OOW12 I tried to attend every xml session I could. There was one where a Mr. Drake was explaining something about not using clob
as an attribute to storing the xml and that "it will break your application."
We're moving forward with storing the industry standard invoice in an xmltype column, but Im not concerned that our table definition is not what was advised:

Hi,
I suggest you read this paper : Oracle XML DB : Choosing the Best XMLType Storage Option for Your Use Case
It is available on the XML DB home page along with other documents you may be interested in.
To sum up, the storage method you need depends on the requirement, i.e. how XML data is accessed.
There was one where a Mr. Drake was explaining something about not using clob as an attribute to storing the xml and that "it will break your application."I think the message Mark Drake wanted to convey is that CLOB storage is now deprecated and shouldn't be used anymore (though still supported for backward compatibility).
The default XMLType storage starting with version 11.2.0.2 is now Binary XML, a posted-parsed binary format that optimizes both storage size and data access (via XQuery), so you should at least use it instead of the BASICFILE CLOB.
Schema-based Binary XML is also available, it adds another layer of "awareness" for Oracle to manage instance documents.
To use this feature, the XML schema must be registered with "options => dbms_xmlschema.REGISTER_BINARYXML".
The other common approach for schema-based XML is Object-Relational storage.
BTW... you may want to post here next time, in the dedicated forum : {forum:id=34}
Mark Drake is one of the regular user, along with Marco Gralike you've probably seen too at OOW.

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

Need advice about best characterset for XMLDB

Hi,
Oracle 9.2.0.5 Windows 2000
Please, give me an advice about best character set
configuration for XML DB.
During installation Oracle istallator suggests
charset =AL32UTF8 for multilingual data and ncharset=
AL16UTF16.
Is it good settings for database, which will be
used for usual multilingual data and XML DB ?

Yes, we strongly recommend the use of AL32UTF8 for XML DB.

Best practice for application debug logging?

I am building a webcenter portal using Oracle Webcenter 11.1.1.1.5 and deploying on Oracle Weblogic Server 11g. Please suggest what is the best practice to use for application debug logs. Should I use log4j or Apache commons library? Is it possible to manage the logs (enable/ disable/ change severity) of the logs using WLS admin console?

Need advice on best setup for Extreme and Express w/ (n only) network

I'd like to get some advice on the best setup for my situation. I've read a number of posts on WDS, Extending a Network, etc. and, unfortunately, I'm now more confused than ever.
We have an Airport Extreme 802.11n using WPA2 Personal, 2.4Ghz (n only connection) which I've found to give us the best range/connection speeds for the following devices (all computers running 10.5.5, Apple TV's using most current update):
(2) MacBooks
iMac
(2) AppleTVs
The good news we have a large house, the bad news we have a large house. Meaning of course that I don't get the range in parts of the house I'd like to. I also have an older Mini (G4) connected to the AEBS thru ethernet (the Mini acts as the iTunes server for the ATVs).
I just bought a new Airport Express with the desire to place it on the other side of the house to both enhance the range of the wireless network and to provide another wired to wireless connection to the network.
I initially merely chose to "Extend a wireless network" but that seems to have a MAJOR adverse impact on the speeds of the wireless network. dropping the streaming to one of the ATV by like 90%. I would like to maintain the security settings I have as well as the 2.4Ghz (n only) since these provide the best speed/connection range on the AEBS.
My question then is what is the best way to use the AX (WDS? Bridge?).

The best way to use it is the option you chose "Extend a wireless network".
WDS forces you to the much slower 802.11g and even cuts that bandwidth in half.
Operating as a bridge has nothing to do with wirelessly extending a network. Changing this option won't have any effect on wireless bandwidth.

Advice on best app for tracking iphone

I want to be able to track my kids iphone behind the scenes, what is the best app for this. I do not want my child to know the app is running.

Yes, I kind of guessed that. What I mean to say is that the service must not depend upon an App running upon the phone but uses the towers themselves and the inbuilt GPS providing the location.
The alternative would be a hacked phone with the hacking done by AT&T instead ?

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.

Advice re best practice for managing the scan listener logs and list logs

Hi friends,
I've just started a job as a RAC dba administrator for some big 24*7 systems, I've never worked with clusterware and RAC.
2 Space problems
1) Very large listener_scan2.log in /u01/11.2.0/grid/log/diag/tnslsnr/<server name>/listener_scan2/trace folder
2) Heaps of log_nnn.xml files in /u01/11.2.0/grid/log/diag/tnslsnr/<server name>/listener_scan2/alert folder (4Gb used up)
Welcome advice on the best way to manage these in the short term (i.e. delete manually) and the recommended practice and safest way (adri maybe not sure how it works with scan listeners)
Welcome advice and commands that could be used to safely clean these up and put a robust mechanism in place for logfile management in RAC and CLusterware systems.
Finally should I be checking the log files in /u01/11.2.0/grid/log/diag/tnslsnr/<server name>/listener_scan2/alert regulalrly ?
My experience with listener logs is that they are only looked at when there are major connectivity issues and on the whole are ignored.
Thanks for your help,
Cheers, Rob

Have you had any issues that require them for investigative purposes? If not, just remove them. Are the logs required for some sort of audit process? If yes, gzip them to a location where you can use your OS tape backup policies to retain them for n-days. Once you remove an active file, it should recreate the file and continue without interruption.

Advice on best workflow for large Motion project

I am a part-time video editor/designer/motion graphics creator/etc. Normally, I work on projects with pieces no longer than 5 minutes, even if the projects themselves might be 30-40 minutes of total material--mostly video support for conferences and awards shows.
Right now I am embarking upon a mark larger project--10 30-minute segments, each of which is 100% motion graphics. They all involve a speaker against a green screen for the entire segment with the motion graphics keyed in front of and behind him.
We recorded this directly to hard drive in a studio that had a VT4 (Video Toaster) system, so the best Mac-compatible codec they could provide me for clean green-screening was full-resolution component video. This is giving me great keys, but I also have about 500 GB of raw footage.
In this project, I need to first edit all the takes from each episode into a clean 30-minute piece, and then add the motion graphics. And this is where my question comes in. It seems to me FCP is much better for editing the raw video, but that Motion is where I want to do just about everything else. I need to somehow bring the video into Motion, because I want to create "real" shadows against my background from my keyed footage.
When working with a long project, and with a full-resolution codec, what is my smartest workflow? I am trying to spend the least time possible rendering back and forth, and also avoid generating huge in-between files each step of the way. It seems that any way to approach it has plusses and minuses, so I want to hear from people who have been there which path gets me to my goal with the least hassle.

I need to somehow bring the video into Motion, because I want to create "real" shadows against my
background from my keyed footage.
"Real shadows are only faked in Motion. You have many options including a simple drop shadow or a copy of your matte layer filled with a gradient and a gradient blur applied with a distortion filter so it appears to be projected onto the wall. Be sure to take the time to make this a template effect and to keyframe the shadow angle if the foreground subject moves.

Well, you've got two conflicting interests. One, you have to sync the Motion work with the video of the keyed speaker and, two, you have to edit. But it seems to me that your planning must include lots of design work up front, media you can re-use or modify slightly, text formatting that can be precomped, a large stock of effects you will apply over and over again. Do all of this stuff first.
You also want to explore working at lower rez through your planning and roughing stages. for instance, there's no reason to pull a full rez copy of your foreground into Motion if all you need to do is sync to his audio and get rough positioning. You can put him over black and export all of his clips using any medium to low rez codec at reduced frame rates and just use the Screen Blend Mode to drop him roughly onto your Motion projects.
You'll get lots of advice over the next few days. If you're posting to other Motion or motion graphics forums, please do us all a favor and return someday to all of your threads and tell us what you did and what you learned.

Advice on best arrangement for home network

This is my first post so go easy on me....please?!
I have moved into a new apartment and am trying to set my network is the best way, but am struggling slightly.
I have a WRT150N and WRVS4400N (Don't ask why I have both) both of which are brand new, 3 wireless-G enabled laptops an wireless Xbox 360 and soon a LinkTheater or Helios media player, and this is my problem;
My apartment is over 2200 sqft and long with two rooms at one end and the lounge and main bedroom at the other. One room acts as my home office and this is where I want all of my network mess and cables to be hidden, but my wireless doesn't seem to like that.
If I have either router in the office I have no little or no signal in the lounge and no signal in the master bedroom, however if I put the router in the lounge then I have a good signal everywhere, including the office. So it seems that the office room is the issue simply for broadcasting. I have tried all of the normal checklists for improving router signals, but nothing has worked well from the office.
Well you'd think I'd have my solution then....not exactly!
I also have a Buffalo Terastation Live NAS which is part of my network and acts as my print server and main network storage for music etc. and as I really don't want it and the laser printer in the lounge having the main wireless router in the lounge is not the solution.
The apartment building is rigged with fibre optics so I have two internet access points, and I can connect the routers to these and have the same IP address SSID, pass keys etc, and tehrefore when one signal drops out teh other is picked up, but that only gives me internet and doesn't give me access to the NAS and printer which is what I ultimately want.
On version 1.0 of the WRT150N I see 3rd-party firmware can be used to provide a wireless bridge mode amongst other things, but I don't see any other options out there.
Any suggestions?
Am I overlooking something or do I need to simply decide on an expander or one of the WAP products to add in?
I don't want to swap to Wireless-N as that means I'd need something for all of the laptops.
The internet access points in the house don't seem to be linked to one another directly, but getting a straight answer out of someone here is more trouble than it's worth, so is it something I can check easily, and if so could I link through these do you think? (I don't think so, but I am new to network stuff).
Sorry for the long story....hope someone managed to read it all the way to here!
Message Edited by Gambba on 03-26-2008 04:37 PM

The WRT150N has no brdging capability and if your planning to use a 3rd party firmware it will void the warranty of the router. I believe your your only option here is to place the WRVS4400N in the lounge since other location is a dead spot.

Best technology for creation of a web portal

hello everybody,
i want to create a 3-tier web portal and am confused about the implementation in either ASP or JSP. Can somebody please guide me which is the appropriate technology and the flexible one regarding future changes.

your in a java forum, so the answer is: use java/jsp.
For a developer point of view I would say: use the technique you are most familiar with.

Need advice on best approach for Time Machine on Macbook

I have several external disks attached to my iMac, one of which is the Time Machine disk for that computer. I just got a Macbook for my wife and I am trying to figure out the best way to use Time Machine with it. I am thinking the easiest would be to add another external hard disk to my iMac, make it sharable and have the Macbook Time Machine backup over the wireless network to that disk. That way it can back up no matter where it is in the house.
But I am new enough to the Mac that I don't know if that is 1) possible 2) the easiest. I got the sense that I could buy an Airport and attach a hard disk to that but it seemed like a kind of expensive solution.
Any comments/ideas? I am trying to do this as simply as possible without it costing a bunch.

bobmcgraw
Yes, in theory. This is exactly how i have been using time machine... however I have just come up against a major issue with this.
I was backing up my Macbook Air, by using a drive attached to my iMac, and the iMac was sharing the drive. I could happily connect, and configure time machine on the Macbook to use the drive, and away it went.....
Looking at the drive itself, I had a folder for my imac backups... and for the Macbook there was a 'sparsebundle' image.
All seemed well, and Time Machine functioned as expected on the Macbook Air.
The problem occurred when I decided to replace my Macbook Air with a new macbook. Once I had set up the new machine, I thought I could use the time machine backup to restore the new macbook with the old macbook Air's details (in much the same way as I would assume that I could restore back to a new unit if the old machine had failed).
Even with the time machine volume mounted on the new Macbook, the 'sparsebundle' Macbook air was simply not recognised as a backed up machine. Whenever I tried to use the migration assistant to restore back my data, the ONLY time machine backup that it would find on my Time Machine drive was the iMac's one... not the Macbook Air's.
So.... in short... If you chose this option, It is fine for backing up, and restoring as far as it goes... but beware if you ever need to restore the machine in its entirety using migration assistant or the like - as it doesn't seem to work.
Now I have discovered this, I really need to re-think my setup - perhaps share the volume by plugging it into my Airport Extreme Base Station.
The unfortunate situation is that the current backup is absolutely useless in its present form, as one of the things I need to protect myself against is machine failure,and I need to be able to restore a new machine to look like the old one. In this situation I was able to connect BOTH old and new macbooks to the network, and use migration assistant to migrate from one to the other. All was well there, but this would not have been an option if I did not have access to both machines.

Advice on Best practice for inter-countries Active Directory

We want to merge three active directories with on as parent in Dubai, then child in Dubai, Bahrain and Kuwait. The time zones are different and sites are connected using VPN/leased line. With my studies i have explored two options. One way is to have parent
domain/forest in Dubai and Child domain in respective countries/offices; second way is to have parent and all child domains in Dubai Data center as it is bigger, while respective countries have DCs connected to their respective child domains in Dubai. (Personally
i find it safer in second option)
Kindly advise which approach comes under best practice.
Thanks in advance.

Hi Richard
Mueller,
You perfectly got my point. We have three difference forests/domain in three different countries. I asked this question becuase I am worried for problems in replications.
And yes there are political reasons due to which we want to have multiple domains under one single forest. I have these following points:
1. With multiple domains you introduce complications with trusts
(Yes we will face complications that is why I will have a VM where there will be three child domains for 3 countries in HQ sitting right next to my main AD server which have forest/domain - which i hope will help in fixing replication problems)
2. and
accessing resources in remote domains. (To address this issue i will implement two additional DCs in respective countries to make the resources available, these RODCs will be pointed toward their respective main domains in HQ)
As an example:-
HQ data center=============
Company.com (forest/domain)
3 child domain to company.com
example uae.company.com
=======================
UAE regional office=====================
2 RODCs pointed towards uae.company.com in HQ
==================================
Please tell me if i make sense here.

Best location for application files

In our current WebLogic environment (WLS 4.51), we have seperate document roots
for each of te 12 seperate applications being served up in seperate WebLogic instances.
We are migrating to WLS6.1, and I am not sure if I should continue this practice.
All applications will be under the same domain, and some common utility .jar and
.war files may be targeted to several servers in the domain (email servelts, search
servlets, etc.). However, I am no tsure I want all these directories or .jar/.war
files to beunder the same "applications" folder. If I put them under /apps/Java/$app_name/
I can deploy them fine from the console. If I do this, will I lose the auto_deploy
feature? Is there any inherent dangers to doing this? Mostly, I want to keep app1's
files in a different location than app2's.

Please see my inline replies:

be auto-deployed. It is necessary to keep the applications in the
/config/domain_name/applications directory, if you want to have the auto-deploy feature to
work. Also, we recommend to use auto-deployment only during development and turn off the
feature in the prod environment.
Is there any inherent dangers to doing this? Mostly, I want to keep app1's
files in a different location than app2's.Maybe this strategy helps you:
You can have all the applications in the applications directory in the exploded dir format. In
this case, they will be auto-deployed on the Admin server. Using the console, you can target
them to different servers in the domain (analogous to different WLS 451 server instances).
Now, if you change a particular file (jsp) in the webApp, then you will need to just touch the
REDEPLOY file. The Admin server will check that the timestamp for this file has changed and
redeploy the application to the concerned target servers.
So, by maintaining an exploded directory structure for each webApp in the applications
directory, you will be able to keep the files separate and still achieve redeployment.
More details can be found at:
http://e-docs.bea.com/wls/docs61////adminguide/appman.html#1029683
Also, as everything is a webApp now, each webApp has its own documentRoot. So if you have 12
webApps, each has a different docRoot automatically.
hope this helps.
