Built in support for MapReduce in SAP Hana and SQLSCRIPT

Is it possible to define Pure functions in SQLSCRIPT explicitly as a Mapper or a Reducer?
In Monday, April 20th I was reading this document : http://help.sap.com/hana/sap_hana_sql_script_reference_en.pdf and it was mentionning this feature with code examples.(In chapter 3 "What is SQLSCRIPT ?")
But starting from Tuesday, April 21st it is no longer mentionned as it seems that the document as been updated.
This is very confusing.
Does this mean that the feature is dropped?

Checking the version of the file I saved to my hard drive (V1.1 from 2015-02-16) I cannot find anything in the "What is SQLScript" chapter that even talks about MAP/REDUCE.
In fact, there is nothing about this in the whole document.
From a programmer point of view, you actually don't have to do that yourself.
While SAP HANA internally uses concepts similar to MAP/REDUCE in order to parallelise and distribute data processing, this is not something you can or should build in SQLSCRIPT.

How to - Extract data from Cloud For Customer into SAP HANA system

Hello Community,
I have a requirement for extracting the existing data from Cloud for Customer into separate SAP HANA Box.
Is it possible to achieve the same ? If yes, Please guide me for the same.
Awaiting quick response.
Regards
Kumar

Hi Kumar,
In addition to what Thierry mentioned you could also use the C4C integration via standard Operational Data Provisioning (ODP) interfaces. This integration was acutally built for SAP BW and allows you to access any C4C data sources. From my perspective you can also build upon that for a native SAP HANA integration. Please also have a look at this guide: How To... load SAP Business Suite data into SAP... | SAP HANA.
Besides that question let me also add the following: SAP Cloud for Customer already runs on SAP HANA since Nov. 2013. You may also use the powerful built-in analytics within C4C for analyzing data and any of your reporting demands. If your report should consider external data as well, you can combined the existing C4C data source with an external, so-called Cloud Data Source. More infomation is published in the C4C Analytics Guide: http://help.sap.com/saphelp_sapcloudforcustomer/en/PDF/EN-3.pdf.
I hope this helps...
Best regards,
Sven

Does OS 9 have built in support for external Iomega Zip drives?

Hi,
Does OS 9.x have built-in support for external SCSI Iomega Zip drives?

Yeah, you are correct, but Iomega's drivers & APPs were one really destabilizing factor for OS9, as well as ruining a few ZIP Disks with that Death Head crash, and being a nuisance. Intech's drivers gave twice the R&W speed, never failed, never crashed, could Format & Partition them... also worked for MOs, JAZZ, SyJets, other Syquests from 44MB to 550MB, and any other drive regardless of IDE, SCSI, FW, USB.

What technical components are needed for integration of SAP BI and BO?

Hello,
What technical components are needed for integration of SAP BI and BO?

Hi,
you need to setup a BOBJ server (eg. BusinessObjects Enterprise XI 3.1 or BO Edge 3.1) and then install the BusinessObjects integration Kit for SAP on the same machine your BOBJ server runs.
In order to build reports you can either use Crystal Reports (eg Install Crystal Report Designer 2008 V1 if you have an XI 3.1 server installed), WebIntelligence (Install the Business Objects XI 3.1 Client Tools in order to be able to build universes), BusinessObjects Voyager or XCelsius. Please note that you have to always install the BOBJ integration Kit for SAP (should be the same version as your server and client installation) on your clients AFTER you installed one or more of the above client tools.
Please take again a look at the following link for more detailed information (from Ingo) on this:

BDB support for Windows Vista, WIndows 7 and Windows Server?

Hello,
I examine to use BDB on Windows, and I have a question.
There's a description about supported OSs on the BDB reference guide as follows;
Where does Berkeley DB run?
The Berkeley DB distribution includes support for Windows/95, Windows/98, Windows/NT, Windows/2000 and Windows/XP, via the Microsoft Visual C++ 6.0 and .NET development environments.
Does BDB distribution supports for Windows Vista and Windows Server 2003?
And it will support Windows Server 2008 and Windows 7?
I believe that BDB does not depend on specific function of Windows, thus there's no problem to support them...
Regards,
Akira

Yes, we have a plan about BDB support for Windows Vista, Windows 7 and Windows Server. Once we are ready, we'll let you know here.
Hi Vit,
For Berkeley DB XML questions, please go to the Berkeley DB XML forum at: Berkeley DB XML
By the way, I learnt there's a XP-compatible mode in Windows 7. You may want to try DB-XML with that.

Hi Denish,
You have 2 ways of loading data from R/3 to APO.
1. R/3 to BW cube to APO-BW cube to APO planning area
or
2. R/3 to APO-BW cube to APO planning area
BW can be a enterprise BW system ( independent) or you can use the BW inbuilt in APO also referred to as APO-BW.
The only difference between the 2 BW systems is APO-BW can not take the load of reporting where as the enterprise BW can.
Unless your company policy requires the enterprie BW system, I suggest using 2nd way.
You can load the data from R/3 to APO-BW cube using extractors either generic or standard depending on your data. You need to have a RFC connection setup between APO-BW and R/3. ( This is not CIF).
When you load the data into the APO-BW cube, you just have to load the data from the cube to APO planning area using the transaction /sapapo/tscube.
Refer to [DP Data Mart|http://help.sap.com/saphelp_scm50/helpdata/en/13/5ada58309111d398250000e8a49608/frameset.htm] for more information about the data transfer between APO-BW and APO.

IWeb protocol support for anything OTHER than http and https

I am extremely disappointed in iWeb. It doesn't even seem to be able to do very simple things.
All I want to do is to create HTML links to external pages with protocols other than "http" and "https" and it always prepends "http" to the beginning of the URL. This is really really really annoying.
Apple I hope you are paying attention. iWeb is poorly designed. You are trying to anticipate what end users want...this is a development practice right from the Microsoft Windows Developer book. I sure how the next update to iWeb works properly. I'm so upset about all this...I can't publish podcasts to the web because of all the foolishness with how you handle that, and the confusing directory name issues.
My podcast URL looks like this:
http://itpc://www.mysite.com/podcast/News/rss.xml
I tried (unsuccesfully) to manually create the podcast since the automated version created this:
itpc://www.bradyconsult.com/podcast/podcast/News/rss.xml
I'm sure I could fiddle with iWEb and get this to work, but why should I? I've already fiddled with it and simple changes to my site structure totally screw this up. Not to mention, that when it did work, it didn' t even post all my podcasts!!! It skipped the first one and the last one.
And, for those wondering, i'm not technically clueless. I have a podcast working just fine on two other sites. The appeal to iLife with iWeb and the new podcast feature of GarageBand was to bring all this together in one easy to use, nice package. But it's not nice. Garageband's update is awesome! But iWeb and it's attempts to work with the other iApps is gruesome.
I expect this garbage from Microsoft...not Apple.
Can anyone recommend a workaround (and yes, I understand I can manually edit HTML...but I was hoping for a workaround within iWeb) to create html links with support for protocols (aside from http and https) ??
It's bad enough I have to publish to a folder and then FTP to my site since apple makes that exceedingly difficult to do (I'm sure to increase .mac sales) but all this other foolishness is just bunk. I feel ripped off on my iLife '06 purchase.
Grrrrrrr......
G5 Dual 2.3 GHz Mac OS X (10.4.5)

I don't know if this helps you any, but in my humble
opinion Drake is absolutely correct. iWeb really
wasn't designed for the pro site builder; it's just
an entry level site builder. Moreover, it isn't
really geared for the professional world of internet
marketing; I think it is really more for the home
and family group who have at least one thing in
common: Macs.
I don't think it was even designed for them. I mean, you can't create an ftp: link, you can't manage multiple site files, there's no way to add "aim:" or "yahoo:" links, etc. It's not mac's they're supporting. It's .mac in particular, maybe, if that.
The art is kinda nice, but really, the grief in trying to do simple things like a basic href is just absurd. I can do these things easily in Pages. iWeb should certainly be no more difficult.
Btw, I'm here because I have the same problem - overly restrictive URL's on hyperlinks. I'll probably solve my with a trivial sed script. But even that's tough because they mangle the url. It's not easy to find an encoding suitable for automatic post processing.
Automator anyone?

Best Approach for Reporting on SAP HANA Views

Hi,
Kindly provide information w.r.t the best approach for the reporting on HANA views for the architecture displayed below:
We are on a lookout for information mainly around the following points:
There are two reporting options which are known to us and listed below namely:
Reporting on HANA views through SAP BW (View > VirtualProvider > BEx > BI 4.1)
Reporting on HANA views in ECC using BI 4.1 tools
Which is the best option for reporting (please provide supportive reasons : as in advantages and limitations)?
In case a better approach exists, please let us know of the same.
Best approach for reporting option on a mixed scenario wherein data of BW and HANA views is to be utilized together.

Hi Alston,
To be honest I did not understand the architecture that you have figured out in your message.
Do you have HANA instance as far as I understood and one ERP and BW is running on HANA. Or there might be 2 HANA instance and ERP and BW are running independently.
Anyway If you have HANA you have many options to present data by using analytic views. Also you have BW on HANA as EDW. So for both you can use BO and Lumira as well for presenting data.

Built-in support for web streaming camera?

Hi,
I have a Sony MiniDV camcorder that supports web streaming.
Is there any built-in software support for web streaming?
If not, could someone please recommend software that will allow me to setup my camera in my house and view the streamed data over the internet?
Thanks!!

You can download Quicktime broadcaster for free to do this. See http://www.apple.com/quicktime/broadcaster/
We've used it to stream a live event from an art gallery and then to a Quicktime Streaming Server (available free in the Darwin version) to broadcast to the world.

SAP HANA and UI5 documentations

Hello Experts,
I am looking for the right blog, sites or documents where i can download and setup SAP HANA trail edition into the personal system.
Also wandering for the appropriate sites, blogs or documents where we can learn the integration of SAPUI5, JPA eclipselink, SAP HANA using either netweaver gateway or apache tomcat via different services like AJAX, ODATA, and JSON.
I would really appreciate if you help me on these topics.
Thanks and Regards,
Vicky.

Is AIX7.1 and MS Windows 2012 supported for JavaCAPS5.1.3 R4 and JavaCAPS 6.3?

Does AIX 7.1 and MS-WIndows 2012(and cluster) supported for JavaCAPS5.1.3 R4 or JavaCAPS 6.3?

John provides another possible workaround for your issues :
http://www.metavero.com/index.php?option=com_content&view=article&id=44:making-ie8-work-on-hyperion-11x&catid=1:latest-news&Itemid=50
My situation is slightly different. We are upgrading to most recent version of Hyperion in 2012 and are not looking to apply service packs/updates to 9.3.1 in the mean time; however, we needed IE 8. We performed the javascript fixes and our users are able to perform their work just fine.
I would also agree that XP mode is not that answer.
Another option would be to install IETester as it lets you 'convert' your IE browser to be compatible with previous versions.... http://www.my-debugbar.com/wiki/IETester/HomePage
Finally, you could have users use Firefox browser as that seems to work; however, it does SOME things differently than IE so you might get some complaints about that.

BlackBerry Enterprise Cloud Services - MS Exchange Online Plan 2 - Support for Legacy 7.1 Devices and Costs?

Hello.
All questions below relate to the MS Exchange Online Plan 2, and BlackBerry Enterprise Cloud Services (BBCS).
- How much does it cost to install the BBCS service?
- Is there support for legacy 7.1 BlackBerry devices?
I have searched online for these answers but I've been unsuccessful answering these two questions. I'm aware that BBCS is available
for the Exchange Online Plan 2 but I cannot confirm if there is a fee. Likewise, I've been unable to find out if legacy 7.1 OS BlackBerry devices are support on BBCS.
Many thanks.

I recommend that you post this in the Exchange Online (Office 365) Forum:

Question on Support for XML in Oracle 9i and XDK 9.0.1

Hi All,
I just went through the Oracle 9i's features for XML. I have been working with Oracle's XDK too. I noticed that there are some new packages in Oracle 9i like SYS_XMLGEN and DBMS_XMLGEN that produce a XML file when presented a query to it. This feature is there in the XDK (XML SQL Utility) too. So, my question is as follows:
1. Are there any differences in the XML File produced by XDK and these database packages?
2. What are the scenerios when I should go for these packages and when should I go for the XSQL Utility.
Cos I found out that both are doing effectively the same things. Is there any difference between them? Please explain the second question.
Thanks in advance,
Rajat

The sys_xmlagg and sys_xmlgen are native implementations of functionality tied into the database code line. They replicate some of the functionality that was previously provided in a 'plugin' form by the XDK. DBMS_XMLGEN is a PLSQL Package that also provides access to native implimentations of some of this functionalitu. You should find that as a result of being native implimentation they are much more performant.
SYS_XMLGEN and SYS_XMLAGG allow XML to be generated directly from a SQL Query. DBMS_XMLGEN is designed for use in procedural processing and provides a finer grain of control over the generated output.
There are still some features, such as DTD and Schema generation that are not (yet) available with the native implementation, and for this reason, and backwards compatability the XDK functionality is still available
As a rules of thumb, if you can use the native implimentations do so, as performance should be much better.
