What are the Pros and Cons while joining tables at DF and Universe level

Hi Experts,
I am new to Data federator designer. I need help on the below.
Could you please let me know the Pros and Cons while joining the source tables in data federator
And While joining the DF target tables in universe designer.
Regards,
Gana

Hi,
1. I have created target tables based on source tables with one to one mapping and then join all target tables in universe.
Ex: Source tables: Infocube text tables, fact tables and 3rd party data base table
Target tables:Target tables are same as source tables
--- Yes this is the way to create target Tables and join them in the universe.These target Tables gives you the flexibility like in future your requirement is to add one more object based on some calculation which is not possible in the universe so that time you can create one more column in the target table and do the calculation. at the same time if you are using source table you can not do anything.
2. Created single target table with all objects of source tables and merged all sources tables data.
Ex: Source tables: Infocube text tables, fact tables and 3rd party data base table
Target table: Single table.
--- This is bit complex structure to merge all tables data in the one target table.in this situation you have to put more efforts and it is more complex.basically this type of target table is useful when you are merging data by multiple source into single or creating one target table based on the union of tables by adding two mapping rules or more and you can not join tables in universe.
Better approach is first 1. create target tables based on the source tables and join them in the universe.
Thanks,
Amit

What are the pro's/cons of the iphone

hi there you lucky Americans, can u tell me what are the good and bad points of the iphone
thanks

Cons:
Have to have the phone activated before you can use ipod and wireless features. No AT&T contract = iBrick.
No custom ringtones.
No "`" (the accent grave) on the keyboard. Probably only the French will care, and Apple probably doesn't care about the French.
Sub-par browser with no Java/Flash support. No choice for real browsers (Opera or Firefox) is allowed.
No video mode/zoom on camera.
No 3rd party applications.
No stereo bluetooth support. You have to use the wired headphones to listen to music in stereo.
Things that are cute the 1st time (the slider you use to open the phone) are annoying by the 10th time.
Pros:
Cost of phone keeps Apple employees off the street.

What are the pros and cons of installing java+abap stack for portal?

Hi all,
1.What are the pros and cons of installing java+abap stack for portal?
2.what effect it does on the ume options to be choosen??
3.for the purpose of integration of r3,bw and crm on portal and crm 4.0 60.2.3 business package which option of stack(java or abap or both)will be good option and which ume option while installation should be choosen?
regards
Rajendra

Hi Rajendra,
The NetWeaver Installation Master Guide offers some good scenarios on the pros and cons:
https://websmp201.sapag.de/~sapidb/011000358700005412792005E.pdf
In a nutshell:
ABAP+JAVA
Pros
- Decrease # of servers required to administer the portal
- Less costly
Cons
- Upgrades could be dependent on ABAP and Java release level
- Additional load on the server due to ABAP stack
- Limited scalability
JAVA and ABAP on separate server
Pros
- Improved performance
- Allows each system to be single-use purpose therefore downtime does not affect other components
- More scalable
Cons
- Adds complexity to landscape
- Additional costs

HT204053 What are the pros and cons of 1) choosing to use the SAME Apple ID for iCloud services on one side, and purchases on the iTunes Store, App Store, and iBookstore, on the other side; or 2) to have and use two separate Apple Ids for these "two sides

All is in the title, so I repeat it below with a better identation.
What are the pros and cons of
1) choosing to use the SAME
Apple ID for iCloud services on one side, and
purchases on the iTunes Store, App Store, and iBookstore, on the other side; or
2) to have and use two separate Apple Ids for these "two sides"?
P.S.
I have loads and loads of free podcasts in iTunes in my iMac, that are certainly more thant the 5 gigas the iCloud provides for free, so I don't want those to go to the cloud. But this is perhaps a different question...
Also need to mention that I have itunes on a mac, a pc and an iphone.
Sorry to look so silly with this question, but I don't get the "big picture".

You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

Samplers do alot of things, what do you need a sampler for?
Korgs remind me of alot of presets and alot of verb and chorus. I guess if you're posting here you already have EXS and want more sounds or more functionality and if the korg thing is true you lean more to sampling/synthesis than instrument recreation (as in you probably aren't going for VSL if the korg caught your ear). Independence looks really cool, it's quite new. Kontakt is demanding and very flexible, both include huge libraries and I know kontakt has tons of great filters, FX, modulation. It also needs a pretty strong update-which is being dealt with after a year or so.

What are the pros and cons re using an intel iMac vs MacPro with LP8?

I'm considering getting a new intel Mac in the near future (presuming a new MacPro will be released in the near future - maybe at the same time as Leopard). I compose largely for film and television and I am composing largely using a combination of loops, software instruments and some recorded live performance. I usually sync to a low res quicktime movie.
I do like the idea of a simple and uncluttered work environment with an iMac, added to which there's also a degree of portability with the iMac however the MacPro is obviously more powerful. I'm not sure how much the difference in power between the two computers would affect me.
Would I be compromising myself much if I went for the iMac over the MacPro? What are the pros and cons of the iMac vs the MacPro in relation to Logic Pro 8?

In the world large-scale music composition using samples, loops, etc (especially for film) your two biggest needs are RAM and HD speed/access. The imac looses big time in this department (as a single computer at least) as it can only be upgraded to 4gb ram, and only holds one internal HD, and also lacks any PCI expansion for DSP cards, audio interfaces, etc.
In generalyou want to separate your data vs applications as much as possible, to ensure both can be accessed quickly and easily by the computer. So its best to have your system software / applications on one internal HD, and your logic data (samples, audio recordings, loops) on another drive(s). You can do this with an iMac via USB, FW800, & FW400, but depending on how big your projects get, how many USB and FW drives / interfaces you use, and how much data you need to stream, you could overload the buss on the imac (not sure if it has multiple busses or not). Plus speed wise, internal SATA are much faster than external drives, and the mac pro with its 4 internal slots seems like a great choice for speed and flexibility.
However, if you dont find yourself doing large scale projects, then you might be better off going with an imac. We just purchased one for my father and it runs great! It blows the socks off of my Dual 2.5 G5 tower in terms of CPU speed! If you run into problems running things from the imac, you could always add a mac-mini down the road to stream sample libs, as a Logic node, etc, which seems to be a much more cost effective solution.
I hope this was helpful, but I probably just made the decision harder . In fact, if I were to start over today, I dont know if I'd go with a MacPro, or an iMac / mac mini combination. they both seem to have their advantages / disadvantages.
Best of luck!

What are the pros/cons of having 1 large BI system versus 2 medium systems?

What are the pros/cons of having 1 large BI system versus 2 medium systems? Are there any known limits as to how large a BI system can be until it experiences performance problems?
Thanks!

Hi,
I dont think there is any limit as long as your DB and Apps servers support it.
There are case studies on systems from 20 TB to 60 TB.
Regarding having two meduim installations it may not be a right choice if you consider facts like routine maintenance, DB upgrades and reorganization, number of resources required, number of DEV and QUAL servers required (this will increase as each PROD requires one DEV and one QUAL atleast).
If you have a single PROD you can do away with this.
One DEV , one QUAL and a single team of dedicated resources are required to maintain the system.

What are the things taken care while using multiple suites?

Hi all,
I have created a plugin which sends the current file path to an url,
its working fine with debugging in Visual studio 2005 and while it is added to the Adobe Illustrator its works only once.
That is its sending the file path only for one file. While i tried for the second time its not working
I am using following suits in my plugin
AIDocumentSuite
AIFilePathSuite
AIActionManagerSuite
AIUnicodeStringSuite
AIURLSuite
I am using the "AIURLSuite" for calling the url and it is calling the url multiple times while its used alone, and its only working once with the multiple suites.
What are the things taken care while using multiple suites? , is it neccessary to release all variables and the suites after completing the task?
Should they released in the same order in which they are acquired?
Thanks in advance
Sreejesh K V

Hi,
The problem was with the "sAIDocument->GetDocumentModified(mod);"
The "GetDocumentModified" is crashing after executing once, i just removed that statement , and now
i am forcefully saving the document with out checking the modification status!
Its working fine now!
Could you please tell me how can we lock a plugin , or a particular function in a plugin.
There is any specific standard to use the GetDocumentModified function?
Thanks and Best Regards

Hi,
To Configure UD Connect on the J2EE Server for JDBC Access to External Databases;

Configuring the BI Java Connectors
http://help.sap.com/saphelp_nw70/helpdata/en/43/e35b3315bb2d57e10000000a422035/frameset.htm
Then to extract data use this...
Before you can transfer data from UD Connect sources into BI, you have to generate the metadata (the information about the source object and source object elements) in BI, in the form of a DataSource with a function module for extraction.
If your dataflow is modeled with objects based on the old concept (InfoSource 3.x, transfer rules 3.x, update rules 3.x), you can generate a DataSource 3.x for transferring data into BI from a database source system.
Prerequisites
You have modeled the InfoObjects that you want to use in the InfoSource and the data target or InfoProvider according to the UD Connect source object elements.
Note the following background information:
Using InfoObjects with UD Connect
Data Types and Their Conversion
Using the SAP Namespace for Generated Objects
Procedure
You are in the Modeling InfoSource tree of the Administrator Workbench. First create in InfoSource and activate the communication structure. Then generate the generic DataSource using the wizard in the InfoSource maintenance.
1. Choose InfoSources ® Your Application Component ® Context Menu (right mouse click) ® Create InfoSource.
2. Select the type of the InfoSource.
3. Under InfoSource, enter the technical name of the InfoSource, and assign a description and choose Continue.
The system creates an InfoSource and shows it in the InfoSource tree under your application components.
4. In the context menu of the InfoSource, choose Change .
The communication structure maintenance screen appears.
5. Using the previously modeled InfoObjects, create the communication structure (see Communication Structure).
6. Save and activate your communication structure
7. In the dialog box that follows you will be asked whether you wish to activate the dependent transfer program. Choose No.
8. In the InfoSource menu, choose Extras ® Create BW DataSource with UD Connect.
You get to the dialog box where you can assign a UD Connect source object to a DataSource and then generate the DataSource with the extractor. The fields for the DataSource are already being displayed in the table on the left side of the screen. The fields have the same name as the InfoObjects that you have used in the InfoSource.
9. Select the RFC Destination for the J2EE Engine.
Make sure that the local server is running. If the local server is running and you cannot open the table for RFC destinations, start the local server again.
10. Choose the UD Connect Source in which the data that you wish to access is located.
All available sources that are connected to the J2EE Engine are provided for selection in the input help. n instances are available per adapter.
11. Select the UD Connect Source Object.
All available source objects that are available in the selected UD Connect source are provided for selection in the input help. Source objects can be multi-dimensional storage or relational objects.
The system generates the name of the DataSource in the namespace 6B.
The DataSource is then replicated in BI.
The myself system is assigned to the InfoSource as source system as well as the DataSource.
The system generates a proposal for the transfer rules.
Since the DDIC structure and the function module are located in the SAP namespace, the following entries can be requested during generation:
Developer and object key or
Developer key or
Object key and
Transport request
If you do not make the requested entries, the generated infrastructure is not usable.
14. Change or complete the transfer rules as needed. For example, if a source object element is not assigned to a unit InfoObject, you can determine a constant for the unit, such as EUR for 0LOC_CURRCY (local currency).
15. Save and activate your transfer rules.
Recognizing Manual Entries
You can enter and change the RFC Destination, UD Connect Source and UD Connect Source Object manually. In order to validate these entries and the ones that depend on them, choose Recognize Manual Entries. For example, if you change the selected RFC destination, all of the field contents (US Connect Source, UD Connect Source Object, list of the source object elements) are invalid. If you choose Recognize Manual Entries, the dependent field contents are initialized and have to be maintained again.
Result
You have created the InfoSource and DataSource for data transfer with UD Connect. In the DataSource overview for the myself system, you can display the DataSource under the application components Non-Assigned Nodes.
When modeling InfoObjects in BI, note that the InfoObjects have to correspond to the source object elements with regard to the type description and length description. For more information about data type compatibility, see Data Types and Their Conversion.
The following restrictions apply when using InfoObjects:
Alpha conversion is not supported
The use of conversion routines is not supported
Upper and lower case must be enabled
These InfoObject settings are checked when they are generated.
Based on the large number of possible UD Connect sources, the most diverse data types are possible in the output system. For this reason, a compatibility check is made at the time of generation of the UD Connect DataSource that is based on the type information supplied by the source systems. This attempts to decrease the probability of errors during the extraction process.
(Refernce:SAP Notes)
Hope this helps,

What are the endpoints attributes collected by NAC Profiler through SNMP and DHCP?

Hi Everyone,
Please help on this.
I want to know what are the endpoints attributes collected by NAC Profiler to discover and profile the endpoints.through SNMP protocol and DHCP protocol.
Also if anybody can explain a simple used case on this.
Please guide me on this.
Thanks in advance.
Thanks,
Abuzar.

Hi,
SNMP
=====
NetMap queries network devices via SNMP for:
System information
Interface information
Bridge information
802.1X information (PAE MIB)
Routing/IP information
CDP MIB Information
This information is used to Build and maintain a model of the network topology and endpoint discovery.
NetMap uses SNMP Get, GetNext and GetBulk (when available) requests to query the SNMP agents running on the network infrastructure devices to gather specific Management Information Base (MIB) objects about their status based on device type (Layer 2 or Layer 3).
In addition to polling each network device for all MIB data at a regular interval, NetMap may also be commanded to poll port-specific information when the NAC Profiler system is notified that an endpoint has joined or left the network via SNMP traps sent by devices at the network edge, switches typically.
Upon receipt and verification of a link state (link up, link down) or MAC notification trap, NetTrap will notify the NAC Profiler Server that a change has occurred on the network edge (endpoint joined or left a network port). If the trapping device is in the NAC Profiler configuration, the NetMap component module assigned to poll the device that sent the trap will be commanded by the Server module to initiate a poll of the device's port information to determine the change to the endpoint topology that resulted in the trap being sent by the network device.
The information gathered by NetMap is processed by the Server accordingly to update the network topology, noting the endpoint joining or leaving a port. Note that NetMap SNMP polling of network devices resulting from a trap is localized to the port specified in the trap. This is unlike the regular polling that occurs at the frequency specified for each device type (L2 and L3) which gathers all SNMP information from the device used by the NAC Profiler system.
DHCP:
=====
The NetWatch module listens for traffic including DHCP traffic.
The module will collect all the DHCP information on the traffic collected, like mac address, ip address, DHCP Vendor Class Identifier in DHCP request, host name in DHCP request, requested specified options in DHCP request (option 55) and full list of DHCP options supported by the DHCP client as specified in the DHCP request.
All the endpointe data can then be used to map endpoints with profiles.
HTH,
Tiago
