HTMLDB from a DBA's point of view - any docs available ?

Hi,
I'm looking for some documentation for an experienced Oracle DBA who, not being a HTMLDB developer, will soon have to manage HTMLDB workspaces, users, developers, etc. while continuing to manage the larger Oracle database environment.
Apart from the installation guide, most of what I've found so far is pretty much developer-oriented (which is understandable given the product focus). Maybe I'm missing some documentation that someone can point me too?
Any tips, pointers, etc. are very welcome.
All the best.
Niall.

We're also looking at a best practices approach... Our organization does have an architecture defined for our Java/Oracle applications... we have separate servers for each phase: integration, systest, uat, perftest and production. We have a rigorous, somewhat problematic and lengthy release process for Java applications... APEX being what it is (a RAD tool for web)... will redefine this process a little, and circumvent the existing process shortcomings.
Problem is getting it adopted by various stakeholders (operations, DBAs and architects, IT security)
My vision is that each server (application and database) in each vertical would have an identical APEX set-up... The only exception would be that all environments, except "integration" would be a runnable environment only.. ie developers would not be able to make any changes to applications. Only import a packaged application, developed on the integration vertical.
Where we run into problems, is how do we manage static assets, such as images, scripts and stylesheets etc... the AEPX best practices guide suggests two ways: load them in the database using APEX, or FTP them to the servers. Option 1 is not recommended for high traffic sites, as this will put too much of a burden on the database (every graphic, script and CSS reference in the page would cause a hit to the db)... So option 2 is really our only option in our case. Problem is we do not have direct FTP access to the servers. This is why we have our release process, files are packaged and sent to other groups (QA, operations etc) who then install the files based on the release documentation. This process usually takes about 6 weeks (regardless if it's a full application release, or a simple change to a graphic)...
If we are to use APEX to its full potential, we'll have to address this limitation internally.

From a Technical Architect point of view, how to design a web application?

Hi to all,
I am writing this issue here because I this question is not related on how to program, but on how to design a web application. That is, this question is not related to how to program with the technologies in J2EE, but how to use them correctly to achieve a desired outcome.
Basically I know how to develop a simple web application. I like to use SpringFramework with AcegiSecurity and Hibernate Framework to persist my data. I usually use JBoss to deploy my web applications, however I could easily use Tomcat or Jetty (Since I am not using EJB�s).
However I have no idea on how to develop (or a better word would be �design�) a website which is divided into different modules.
Usually when you develop a website, you have certain areas that are public, and other areas that are not. For example, a company would want anyone on the Internet to download information about the products they are selling, however they would only want their employees to download certain restricted information.
Personally I try to categorise this scenario in to common words; Extranet and Intranet.
But � (and here starts the confusion in my mind) should I treat these two as two projects, or as one project? The content to be displayed on the Extranet is much different then the content to be displayed on the Intranet and definitely clients should not be allowed to the Intranet.
First approach would be to treat them as the same project. This would be perfect, since if the company (one day) decides to change the layout of the website, then the design would change for both the Intranet and the Extranet version. Also the system has a common login screen, that is I would only need to have employees to have a certain Role so that they have access to the intranet, while clients would not have a certain Role and thus they would not be allowed in. But what about performance and scalability? What if the Intranet and Extranet have to be deployed on the different Hardware!?
The second approach is to threat them as two separate projects. To keep the same layout you just copy & paste the layout from one project to another. However we would not want to have two different databases to store our users, one for the employees and the other one for the clients. Therefore we would build a CAS server for authentication purposes. Both the Intranet and the Extranet would use the same CAS server to login however they could be deployed on different hardware. However what if we want to change the design. Do we really want to have to just copy and paste elements from one project to another? We all know how these things finish! �We do not have time for that � just change the Extranet and leave the Intranet as it is!�
The third approach (and this is the one I like most) is to have a single project built into different WAR files. The common elements would be placed in all WAR files. However in development you would only need to change once and the effects would show in the different war files. The problem with this approach is that the project will be very big. Also, you will still need to define configuration files for each one of them (2 Web.config, 2 Spring-Servlet.config, 2 acegi-security.config, etc).
Basically I would like something in the middle of approach 2 and approach 3! However I can identify what this approach is. Also I can not understand if there is even a better approach then these three! I always keep in mind that there can always be more then two modules (that is not only Intranet and Extranet).
Anyways, it is already too long this post. Any comments are more then welcome and appreciated.
Thanks & Regards,

Hi to all,
First of all thanks for the interest shown and for the replies. I do know what MVC or Multi-layered design is and I develop all my websites in that way.
Basically I have read a lot of books about Domain-Driven Design. I divide my web applications into 4 layers. The first layer is the presentation layer. Then I have the Facade layer and after that I have a Service layer (Sometimes I join these two together if the web application is small enough). Finally I have the Data Access layer where lately I use Hibernate to persist my object in the database.
I do not have problems to understand how layering a web application works and why it is required. My problem is how to design and develop web applications with different concerns that use same resources. Let me give an example:
Imagine a Supermarket. The owner of the Supermarket want to sell products from the website, however he wants to also be able to insert new products from the website itself. This means that we have two different websites that make use of the same resources.
The first website is for the Supermarket clients. The clients can create an account. Then they can view products and order them. From the above description we can see that in our domain model we will have definitely an object Account and an object Product (I am not mentioning all of them). In the Data Access layer we will have repository objects that will be used to persist the Account and Products.
The second website is for the Supermarket employees. The employees still need to have an account. Also there is still a product object. This means that Account and Product objects are common to the two websites.
Also important to mention is the style (CSS). The Supermarket owner would like to have the same style for both websites.
Now I would not like to just copy & paste the objects and elements that are common to both websites into the two different projects since this would mean that I have to always repeat the changes I make in one website, inside the other one.
Having a single WAR file with both websites is not an option either because I would not like to have to deploy both websites on the same server because of performance and scalability issues.
Basically so far I have tought of putting the common elements in a Jar File which would be found on the two different servers. However I am not sure if this is the best approach.
As you can see my problem is not about layering. I know what layering is and agree with both of you on its importance.
My question is: What is the best approach to have the same resources available for different websites? This includes Class Files, CSS Files, JavaScript Files, etc.
Thanks & Regards,

From Google Maps user point of view

Hi,
I come from Android and Google 's services.
I'm really impressed by Windows Phone 8 (and really happy too for my migration).
I have bought a Nokia Lumia 620.
One of more important services in Nokia is Nokia HERE Maps, for sure. Because it can replace a central Google service as Google Maps.
By the way some things are missing and I wonder if they are going to be in Nokia Maps or I will never be a 100% satisfied user and will have to deal with it.
My suggestions are:
1. A lot of POI are missing from maps. In the future can a single user add or correct POI simply from his smartphone?
Communities work well usually. It could be also that every place has a number for its actions, so you can trust for a POI with an higher number of interactions despite of a POI with only one random action.
2. Can I save POI to create a personal map and then view it as a layer on the main map?
For example "restaurants in Milan".
3. Nokia Maps still lack of calendar and contacts integration but, probably, it's more on Microsoft.
Thanks!

And a "save to contacts" function too.

From a consumer's point of view (a recent purchaser of an iMac G5)

I understand that new models come out all the time.
Nevertheless, the iMac G5s basically just came out. People, like me, who just bought one did not feel they were buying it at the end of a life cycle, but rather at the beginning of one. Up until yesterday Apple was touting the iMac G5 machine and urging its purchase.
Has there ever been such a major change in an Apple model (Jobs claims a speed improvement factor of up to three times) so soon after release of the previous model?
It is natural to expect some sort of upgrade program. I call it just good consumer sense.
But from previous experience, I doubt Apple will be so considerate of its customers. I would love to be proved wrong!
doug

I bought mine in November and thought that I would have at least a year before we would see Intel iMacs. I am still very happy with my "old" iMac, but there is that little twinge of chip envy. I guess I will just console myself by purchasing a MacBook Pro to replace the G3 iBook.

From the End User Point of view

Hi,
Suppose i have scenario like file to idoc, the file should run every day night,when any errors occur at idoc side how can end user know whether it is successfully updated at R/3 side or not. In this scenario exactly what is role of end user what will he do.
Thanks in advance.
Regards,
Prem.S

Hi Prem,
In this case the end user/basis team/ ie basically who ever is responsible for monitoring has to go to transaction WE02/WE05 to monitor if any error has occured in posting the application document.
if any error is there in WE02 then he can go to transaction BD87 and repost the idocs.
Cheers,
Sumit
ps : reward points if that helped u.

From a Gentooer's point of view...

http://forums.gentoo.org/viewtopic-t-577784.html
Interesting read

Threads in 'gentoo chat' and 'off the wall' often degenerate in virtual cat fights ....
I was a Gentoo user for 4 years (and still have a gentoo system) and switched recently to arch, the atmosphere there was simply no longer the same, and new problems on a daily basis made the mainteinance impossible. I wonder how such problems are (or will be) handled in arch, recently for example the new ABI incompatible libexpat 2.x went stable in Gentoo (after a long delay) and without warning the update removed the old version and told the user to revdep-rebuild their systems. This means scan all executables to find those linked to the old libexpat (and most modern sotware is) and recompile them, leaving scores of users with a crippled system recompiling most application, a daunting task on old systems.
Arch still uses libexpat 1.x how will it be updated in a 'rolling release' fashion without breaking most users systems?
I found about Arch on the gentoo forums since many switched to this fine distro from gentoo and this possibly has upset some there. The only thing I think is better in Gentoo is the USE system but is not that essential in building a system. I mean I may disable completely KDE or Gnome support in all my apps and get (maybe) smaller executables but usually it allows only to remove features from a package and most of the time users simply activate all USE flags defeating their purpose.
Since I switched to arch I have a lot more time to dedicate to actually use my computer (play games, program, whatever) while with Gentoo most of the time was used to recompile things.
The only trick I use is that I have a boot partition not default mounted and I copy manually there new kernel26 updates few days after pacman -Syu installs them, after checking the forums first:-)
The install script for new kernels should really move the old working kernel to vmlinux.old so that users can still boot the old one.

From a designer's point of view...

This hasn't seemed to be talked about much so I thought I would
see if I could get some dialogue generated on the subject.
When it comes to my graphic designers in the Flex workflow:
1. should I keep them in the Flash environment or move them to
the Flex environment?
2. where is the delineation between Flex & Flash (from a
design standpoint)?
3. to what level should things be designed/developed in Flash
vs. Flex?
a. does it make any sense to have my Flash designers doing
anything with the Flash drawing API (or other programmatic design
elements) or is there a Flex equivalent?
4. if I make the assumption to have Flash be used as a designer
for "interactive" elements and Flex for UI and other elements am I
on the right track?

Hi there -
There aren't really any cut and dry answers, but there have
been some posts
and blogs in the past that offer some opinions and can help
get you thinking
about the topic in more detail. Folks like Jesse Warden and
Mike Chambers
have talked about the division of labor between Flash and
Flex and the
designer/developer workflow that can add more color to this
topic. Some of
these postings apply to Flex 1.5, but I don't see too much of
a difference
with Flex 2.
Jesse Wardens' thoughts from over a year ago which might give
some guidance:
http://www.jessewarden.com/archives/2005/01/why_flash_devel.html
Mike Chambers wrote something when we released the alpha of
Flex 2 that
provides some ideas:

Suggestion of a topic for masters project from the Comp sci point of view

I want to decide a topic for my masters project. Preferably dont want to use any hardware. Can i simulate an engine simulator without any hardware.

Simulating a simulator. Yes, that sounds like a very theoretical topic ;-)
But seriously, LabVIEW is a great environment for simulation. NI even has a simulation toolkit for simulating control systems.

TS2771 only getting sound from one side of the headset. Any fixes available?

I have an used Ipod touch. When i connect a headset, i only sound from one channel. Any fixes out there?

- Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
Try the following to rule out a software problem
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for this price. They do not fix yours.
Apple - iPod Repair price
A third-party place like the following will replace the jack for less. Google for more.
iPhone Repair, Service & Parts: iPod Touch, iPad, MacBook Pro Screens
Replace the jack yourself
iPod Touch Repair – iFixit

Lost message from server's point of view

Hi All
Following situation:
The JMS-Provider sends a JMS-Message. The message is entirely in the wire and is still flying to the consumer. Before the message arrives to the consumer, the network connection fails, so the client does nothing know about the send message.
From the server’s point of view the message was successfully sent but not acknowledged yet. The server waits for an acknowledge and doesn’t undertake redelivery, because the consumer session on the server is still living.
From the consumer point of view the message was not sent so the client has nothing to ack, so we have some “deadlock”.
The question is – how does server recognize such situation (short connection fail, deadlock) and what does it undertake to guarantee the delivery?
Thank you.

The question is – how does server recognize such situation (short connection fail, deadlock) and what does it undertake to guarantee the delivery?If the "network connection fails" whilst sending a message then the server (and probably the client) will almost certainly receive a SocketException. A message is unlikely to simply disappear on the wire without at least one end of the socket getting an exception of some kind, and if the socket is simply hanging for some reason then most JMS providers would have a means to detect this (e.g. by sending periodic packets down the wire to check it is still alive).
But ultimately, if a persistent message is sent to a consuming client and the message is not acknowledged (or the transaction committed) then the server will eventually redeliver it. JMS doesn't define exactly when an unacknowledged message is redelivered, but it typically wouldn't happen until the consumer in question has closed.

OIF-What's the diff. from user's point of view of SP/IdP initiated SSO

I'm using OIF for federated single sign on. I got both the SP and IdP initiated SSO works. When I provide both URL to customer, how should I suggest which one to use? from end user's point of view, both of them works in the similar work flow: type(click) URL -> redirect to IdP's login page -> login -> return back to application. only diff. seems the URL. most of user even did not notice the diffrence between 2 URLs.
Could some give some suggestion when and which one is preferred.
Thanks

Probabaly. however, in our case, the application url, e.g. http://appurl is used for non-federate sign on. so that the applicaiton can be run independent of IdP, e.g. IdP down.
To allow federate sign on, we use one of following (as documented in OIF admin guide):
SP initiated:
http://SP host:port/ fed/sp/initiatesso?providerid=<SP provider Id>& returnurl=<http://appurl>
IdP initiated:
http://IdP host:port/fed/idp/initiatesso?providerid =<IdP provider Id>& returnurl=<http://appurl>
So, you can see these does not support bookmark of federate sso since they would return back to http://appurl after federate sign on.
Any suggestion? we couldn't tell good diffrence about above urls to our customer. is there anyway to allow us enable bookmark the federated sso?
Thanks

Client Merge! precautions to be taken from BW point of view

Hi,
We are in a process of merging two clients in R/3 which are typical source systems for BW!
What are the steps that we should take care of while the client merge is on from R/3 side.
these two clients are ofcourse very important for BW system as almost all for everydata load the extraction logic in FM to the ABAP routine in selection of infopacakge is different!
in a scenario such as this, what are the things that should i make a note from BW point of view?

Hi,
1.Internal table with header line will not support in ECC 6.0 for that u need to create internal table and work area using TYPES.
2.Mostly u need to do some PATCH WORK for the STANDARD programmes.
Patch work in the sense for SPAU objects in Mysap is there any code written by client(INSERT {....END INSERT....}) this type of code u need to add in ECC 6.0 code....
3.Mostly u have to resolve EPC(Extended program check) errors.
In that u will find so many type of errors...Field attribute errors,Perform interface errors,Obsolete stetement errors,....etc.
4.First thing u need to what r the SCOPE and OUT OF SCOPE in your upgradation.
5.If u find any Fmodules obsolete...U just press F1 on that Fmodule it will show which function module can useful instead of that obsolete one...
6.If they want UNI CODE compatiable .....
EX Report...
Go to the attributes of the report...
There u can c a check box to check UNI CODE Errors...
U have to resolve these errors also...
After doing all these things u have to show 0 errors on CODE INSPECTOR fro each n every object...
Thats t as per my knowledge...
