Oracle BI general Question

Hi guys,
I am a certified and experienced PL/SQL developer and I want to switch to Oracle BI. Starting to look over the Internet for the documentation, I was quickly overwelmed by the multitude of tools Oracle provides. Basically what I identified as being the top packages are OBIEE, OBISE and Oracle Business Objects. As I am part of a firm that is also quite new at this, but can addres both types of customers (big and small), could you please tell me which one of these packages is better to start with (taking into consideration the market trend and what you`ve experienced)? Can you also please summarise the basic difference between these packages, or provide me with a relevant link, where these products are presented in comparison?
Any help you can provide will be greatly appreciated,
Thanks a lot,
Marius.

The future of Oracle Business Intelligence is moving away from Oracle Discoverer to OBIEE. There are many different tools that you can see in the Oracle Business Intelligence section of edelivery.oracle.com including BI Publisher, OBIEE, OBIA, Hyperion, etc.
You are asking this question in the Oracle Business Intelligence Applications (OBIA) forum, which is a subset of Oracle's total BI offering. You may get a different response posting in the OBIEE forum (http://www.rittmanmead.com/category/bi/).
You can start by reading the data sheets for BI at:
http://www.oracle.com/solutions/business_intelligence/index.html
Also, Mark Rittman is an Oracle ACE Director with an extensive BI blog.
http://www.rittmanmead.com/category/bi/
In the end, what you work on is what the customers are deploying. If you used to work with Oracle Reports, I would get started with learning how to design and customize reports and dashboards in OBIEE and Bi Publisher. If you work in the ERP space, then look into customizing and extending OBIA.

Business Logic in Oracle Applications (General Question)

Hello everyone!
I am relatively new to Oracle Apps and interested in learning and joining this community.
I was trying to figure out how is the Business Logic programmed in E-Business Suite. Is it just PL/SQL or is it BC4J? Is there anyone who could help me answer this question or point me in the right direction (I went through the documentation very quickly (it is rather large so it was only "briefly") and could not find anything that would answer my question exactly)
By Business Logic I mean business-related tasks such as "enter a journal entry" or "issue sales order" (with a higher or lower level of granularity of course)
Any help is much appreciated !

Just to expand on Bala's answer, it depends on how your application is architected.
If you have a Forms based application, then your Business Logic (BL) resides in PLSQL. The forms tier performs the basic validation and partial BL execution and passes the data to the handlers in the database to perform the DMLs and initiate required Business Process.
If you have a OA Fwk based application, then your BL could reside either in BC4J or PLSQL. There are OA Fwk applications that are written that performs some business logic execution within the middle tier and passes the rest to underlying PLSQL code. Take for example an application that was originally written in Forms but later on extended or migrated to OA Fwk. Since most of the BL was already written in PLSQL and some of the forms would still be using the same PLSQL APIs, it essential that the OA Fwk based application too uses those APIs to be in synch.
If you are designing a new application to be based on OA Fwk, it is strongly recommended that you go with your BL as much as on the middle tier.
So it all depends... :)
Thanks

Oracle Grid general questions

Our applications are running on their own application and database servers. We have a mix of hardware including Sun 4800, Sun 450, Sun 280, Sunfire 280, Dell Intel, etc. The OS on Sun boxes is Solaris 8 and on Dell Intel is Windows NT and 2000. To migrate to the grid infrastructure, are we able to make use of our existing hardware or do we need to upgrade them to make them grid ready or do we need to purchase new hardware all together leaving our current hardware investment behind?
When building either database or application cluster, is it possible to have a mix of hardware in the same cluster? For instance, can we have a cluster setup with a Sun box running one instance while a NT box running another?
How is oracle version upgrade handled in a cluster? Do we need to take all of the instances down to upgrade them at the same time or can we do the upgrade one at a time? If the latter option is doable, does that mean oracle cluster can support multi-version instances?
What happens if the upgrade involves upgrading the database as well?
In Oracle 10g, is it possible to run dataguard on two oracle versions at the same time? You run into this situation during oracle upgrade where you are upgrading the standby database while the primary database is running in production. After the upgrade, the standby database will be in a newer version than primary.

Q. Our applications are running on their own application and database servers. We have a mix of hardware including Sun 4800, Sun 450, Sun 280, Sunfire 280, Dell Intel, etc. The OS on Sun boxes is Solaris 8 and on Dell Intel is Windows NT and 2000. To migrate to the grid infrastructure, are we able to make use of our existing hardware or do we need to upgrade them to make them grid ready or do we need to purchase new hardware all together leaving our current hardware investment behind?
A. Oracle Database 10g offers a variety of features for CPU provisioning and Data provisioning that you can use to utilize your resources efficiently. Of course, you get the best resource utilization if you can cluster homogeneous resources and run all your databases on the same cluster. This is not always possible � you may have heterogeneous resources or you may have geographically distributed data centers. For such cases, you can use our data provisioning features to offload processing across these resources.
Our suggestion will be that you start off with the resources you have got now. You use our features that best fit your current IT infrastructure. Later when you want to acquire more hardware resources, you have more choices � you can acquire cheaper low-cost commodity hardware and run your databases on them.
Q. When building either database or application cluster, is it possible to have a mix of hardware in the same cluster? For instance, can we have a cluster setup with a Sun box running one instance while a NT box running another?
A. While building a cluster, you need homogeneous cluster � all the nodes need to have the same OS. Do you really want to have a heterogeneous cluster to run your databases? What about the complexities of troubleshooting o/s or Oracle issues, fail-over, possible port-specific Oracle bugs, the differences in compiled PL/SQL or Java or external procedures? Does any of this make the possible benefits worth it?
Q. How is oracle version upgrade handled in a cluster? Do we need to take all of the instances down to upgrade them at the same time or can we do the upgrade one at a time? If the latter option is doable, does that mean oracle cluster can support multi-version instances?
A. The Oracle Database 10g supports the application of patches to the nodes of a Real Application Cluster system in a rolling fashion. You can apply these patches one instance at a time. You quiesce one instance, apply patch to that instance, and reactivate and rejoin the patched instance to the cluster. While you are doing these, your applications on the RAC database are still running.
You can run system in the mixed mode for an arbitrary period to ensure that the patch corrects the original problem and has not introduced some other problem.
Q. What happens if the upgrade involves upgrading the database as well? In Oracle 10g, is it possible to run dataguard on two oracle versions at the same time? You run into this situation during oracle upgrade where you are upgrading the standby database while the primary database is running in production. After the upgrade, the standby database will be in a newer version than primary.
A. The Oracle Database 10g supports the installation of database software upgrades, and the application of patchsets, in a rolling fashion � with near zero database downtime � by using Data Guard SQL Apply. You establish the standby database using Data Guard. You upgrade the standby database. You can then continue running in this configuration for an arbitrary period of time. Later you can do a database role reversal and switchover of standby to the production database.

Oracle HTMLDB general question

I am currently evaluating HTMLDB as a potential Business Intelligence Portal platform for my company. After playing with it for couple of weeks, I felt that it is far from being a BI platform. It is not a portal either. (I know HTMLDB is not designed for both BI and Portal).
Also, I am not really sure what is the maket positioning of HTMLDB in Oracle's whole suite of products and tools. Anybody have any opinion/comments?

Thanks Scott.
In many cases, all of those requirements can be met
by HTML DB.
1. "real" drill down/up/though data; (not just a
link from a master page to detail page like HTMLDB 2
Days developer demonstrated);
You'd have to be a bit more specific here. You can
pass any parameter to any query, thus re-creating
"drill-down" behavior quite easily.for example, I am looking at some aggregate data at the year level for year 2000-2005, and I expand year 2005, I see 4 quarters, then I expand the 1st quarter, then I see 3 months. And I want all the details data is shown in the original 2005 place instead of linking to another page whichs shows the detail data. To a certain extent, I want to have OLAP cube type of capability. Don't know if this is possible without much effort.
>
2. asynchrnous update(refresh at set interval) of
the chart and report data(in tabular format, eg.).
The chart is pretty easy with HTMLDB, I am still not
sure about the report(another post of me);
With Release 2.0 of HTML DB, you can automatically
refresh report regions. You can also use the META
tag and simply refresh the entire page at a
predetermined interval.Can you point me to a good example?
>
3. certain event management capability(for
example, if inventory level drops below a set
threshhold, then an email is sent to alert
people);
All very possible and quite straightforward with
PL/SQL.
4. personlization UI for each user easily(HTMLDB
has customization for the page, only show/hide a
region - not enough);
Again, all very possible, depending on what you want
to do. Portal does have the upper hand on moving
content around each page on a personal basis, but you
can do similar things with HTML DB - it will just
take a bit more work.
Thanks,

General question on SQL Server 2000 to Oracle 10g

Hello all,
I just have a general question on migration from SQL Server 2000 to Oracle 10g using SQL Developer.
How does it migrate Users with proper privileges from SQL Server to Oracle? Follow the interface steps? Or should the users be created on destination Oracle side?
Thank you.

Hi,
It depends which type of migration you are making.
For a 'Standard' migration when you migrate data a 'create user' statement is created as part of the migration and you will see this in the generated code.
If you are using the 'Quick' migration option then you need to create the Oracle user or use an existing user to receive the data.
Your best option is to review the documentation available from -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
or directly from -
http://download.oracle.com/docs/cd/E12151_01/index.htm
and then get back with specific questions if this does not give you the information you need.
Review the chapter -
2. Migrating Third-Party Databases

Mike

General questions about using webservices and xml as opposed to an oracle driver

Dear Experts; I have a general question which I have yet to test. Is it faster to use an ODBC driver to connect and retrieve data from an Oracle database than creating a .net webservices and using an XML to get the data for your web application. THank you

At some point in the architecture stack some component will need to access the database in order to get the information from the database. That component will need to use an Oracle client driver.

Report Builder Question - OA AR Aging - and a general question

I'm sure this is the wrong forum for this question, but I thought there might be someone here who might be using Oracle Applications and Report Builder who'd be kind enough to help me out.
We've recently implemented Oracle Applications 11.5.10 and I have to use report builder to change the Accounts Receiveable Aging (7 bucket) to a 5 bucket report. I've already made some changes to the seeded "ARXAGMW.rdf" report, but I'm not a big Oracle Reports guy. I've stumbled through making some changes in various other reports. But this one is just plain nasty! :)
I was thinking that I could simply add buckets 6 & 7 to bucket 5, then just hide or delete the 6 & 7 buckets. But I'm not sure where to even start. Any help with this would GUARANTEE a Christmas or other holiday card this year! :)
I really want to keep this simple as possible, so any help would be very....helpful. :)
Oh, my general question is: Are there any resouces/books for Oracle Reports (Report Builder)? I feel so lost trying to modify existing reports, let alone creating new ones.
Thanks again!

Hi Steve,
I am working on the 7-bucket aging report and i want to add a new field in data model.

General question about iTunes Match and multiple libraries

Hello to everyone,
I have a general question about the iTunes Match service, which is available since yesterday in my country (Italy). Currently my library situation is the following:
Computer A (desktop, Windows 7): "big" iTunes library (about 20 GB), at the moment not associated with my Apple ID
Computer B (MacBook Air 2011): "small" iTunes library (about 5 GB), associated with my Apple ID
At the moment, both my iOS devices (iPhone 4 and iPad 2) are synchronized with the smaller library on the MacBook Air.
Question is as follows: should I subscribe to iTunes Match, would it be possible to upload the "big" library (provided I associate it with my Apple ID) to iCloud while keeping my devices synchronized with the "small" one?
Ideally, at the end of the day, the situation should be the following: both iOS devices with music from the small library + possibility of downloading songs from iCloud (coming from the big one). Is this possible?
Maybe the question sounds stupid, but I want to be sure about this before paying for the service.
Thanks a lot.

Yes, you could also associate your larger library with iTunes match if you associated your Apple ID with it. However any purchases in the library made from another Apple ID will not be matched with iTunes much.
If both libraries are part of iTunes match, then all your devices will see all of the content from both libraries, which content you choose to have on those devices and which you have accessible via iTunes match is entirely up to you.

Where to direct a general questions about foreign films subtitles?

I recently purchased a foreign film "Break Ke Badd" from the iTunes store. Although, it didn't specify that it had English subtitles, I assumed it did. After the full download, I tried to watch it and there weren't any English subs. I contacted iTunes and they more than happy to refund the money back to my account. Now after a few weeks, the iTunes store DOES list Eng subs for this film. I don't want to purchase it again and have to contact iTunes for another refund...Therefore my question is, is there a general question contact one could use to find an answer to my question. Basically, to verify that this movie, indeed has English subs before I re-purchase.
Any info is appreciated!

Yes I know as the [https://support.mozilla.org/en-US/questions/ Questions] section is more for desktop Firefox support and the place I linked to is for "Firefox OS" support in English where some who are involved with it do post in it occasionally.
I would have moved that [https://support.mozilla.org/en-US/questions/962783 thread] to the "Firefox OS" English section, however I cannot as the [https://support.mozilla.org//questions/ Questions] and [https://support.mozilla.org/forums Contributor Forums] are not the same.

Camileo charging problem (solved) and a general question!

Hi all!
First of all, I was going to ask for help as to why the Camileo S10 was not charging (the orange light wasn't flashing), and I'd seen a few people with similar problems.
The solution?
Give the contacts on the battery a clean.
The insulation sticker that comes on it must leave some kind of residue on it, and it's enough to prevent charging. Now it's flashing away happily :]
So my general question was, is it possible/advisable to use the camera on the mains?
Rather than constantly draining and charging the battery during long shoots, I'd prefer to just leave it plugged in!
Thanks very much in advance!
Paul

Hi
I think the battery handling is always the same no matter what product it is
From time to time the battery should be recalibrated.
This means that the battery should be discharged fully and after then you should charge it again until the battery would reach 100%
I do this with all my batteries; mobile phone battery, digi cam battery and notebook battery.

Update on Bioinformatics WIKI, scripting challenges, and a general question

I am waiting for my site to go on-line at Oak Ridge National Labs (USA, Tennessee). Should be another week or so, maybe less.
When that happens, you will see a veritable explosion of scripting challenges in my wiki (Emerging Technologies->Bioinformatics.)
One general question in preparation for these challenges.
There are a number of standard bioinformatic programs that can be run interactively via the web at various sites, e.g. "BLAST" and "STRIDE".
Although these can also be run locally, this requires that you download large databases and keep them updated.
So here's my question to the scripting experts:
Are scripting languages powerful enough to submit queries to web pages and then use regex's to parse the html that is returned?
Bill Mann has used PERL to do some of the required regex parsing, but there is a lot left to do, and, his stuff only works when a perl program is invoking a bioinformatic program locally, not interactively.
If so, we all can do some beautiful stuff together , if anyone is interested ...

...my wiki on...
There is by it's very nature no such thing as MY WIKI, except you run your own wiki project in an exclusive mode. Which were...well ... unusual.
Are scripting languages powerful enough to submit queries to web pages and then use regex's to parse the html that is returned?
Yes.

Delete scriptcode - General question: capacity limit of Acrobat Windows

Hello everybody,
I've got a general question to the capacity limit of Acrobat Windows.
I often make forms with
for instance the current one has 18 pages. Eleven pages have fields on it. (But some pages have only one field on it) The fields of one page to another are sometimes linked with script code. The file needs nearly 1 MB.
Usual I write the script code by a double-click on the field/ calculate/ custom calculation script. (Is this the right way?) Today it happens again that a field with script code lost the script code.
That's why I wonder whether there is a capacity limit of Acrobat Windows or whether I make mistakes. (This is only one instance of several where the form has his own life.)
Thanks in advance for helping me!

SAP GRC Process Control - General Questions

Hi all,
We have the following general questions regarding SAP GRC Process Control:
1) Assume that we have set up 5 different SAP Connectors in Process Control. When you configured a specific rule and control and then, schedule the job for such control, how does the system (SAP Process Control) knows which back-end system needs to be accesed for such control?
2) In which language are the out-of-the box rule steps's script coded? In which different languages can those scripts be coded, what is to say, in which language can we code our own scripts?
3) How is the detailed flow between SAP Process Control and SAP Back-end system?
