What is a use case?

Could someone tell me what a use case is? Is it some short of diagram?

No it is not a diagram. A Use Case Diagram is a diagram, but it is not a Use Case.

What are the use cases of Oracle SOA Coherence?

Hi All,
I would like to understand the actual use cases of Oracle SOA Coherence? Also, Coherence is bundled with SOA Suite or we need a separate License for it?

Hi,
Just check below link..would be helpful..

and
Each release of Oracle has many differences, and Oracle 10g is a major re-write of the Oracle kernel from Oracle 9i. While there are several hundred new features and other differences between 9i and 10g, here are the major differences between Oracle9i and Oracle10g:
Major changes to SQL optimizer internals
Oracle Grid computing
AWR and ASH tables incorporated into Oracle Performance Pack and Diagnostic Pack options
Automated Session History (ASH) materializes the Oracle Wait Interface over time
Data Pump replaces imp utility with impdp
Automatic Database Diagnostic Monitor (ADDM)
SQLTuning Advisor
SQLAccess Advisor
Rolling database upgrades (using Oracle10g RAC)
dbms_scheduler package replaces dbms_job for scheduling
and you need to refer oracle documentation for sql, plsql references where you will know particular enhancements made...
thanks

What is WAN compression on AOS 6.4.3.0 and it`s use case?

Q: What is WAN compression on AOS 6.4.3.0 and it`s use case?
A: This feature is supported from AOS 6.4.3.0 and above.
The 7000 Series Controllers contain the Compression/Decompression Engine (CDE) that compresses the raw IP payload data and also decompresses the compressed payload data
Deflation & Inflation
The CDE compression process is called Deflation; the decompression process is called Inflation.
XLP 4xx and XLP2xx Packet Processor Card is a high-performance network processor PCI Express card designed for use in PCI Express compliant systems.
It features the latest Broadcom XLP 4xx series processor with up to 2.5 Gbps per CDE.
This processor is ideally suited to both data-plane applications, which are inherently sensitive to memory latencies, and control-plane applications, which will help best-in-class processing performance.
Advantages
Four CDE channels on the XLP4XX processor and one CDE channel on the XLP2XX processor.
2.5 GBps per CDE (Deflation process, Inflation process, or combination of both)
Deflation context save and restore (at block boundaries)
Inflation context save and restore (at arbitrary file position)
Load balancing the input messages to all CDEs
The Compression/Decompression Engine feature is enabled by default. However, the packets are compressed only if the IP Payload Compression Protocol (IPComp) is successfully negotiated via the Internet Key Exchange (IKE) protocol.
Use-case
Data compression reduces the size of data frames that are transmitted over a network link, thereby reducing the time required to transmit the frame across the network. IP payload compression is one of the key features of the WAN bandwidth optimization solution, which is comprised of the following elements:
You can split a file or data into blocks, and each block can use the mode of compression that suits it best. In this case, it is packet data and there will be only one block.
IP Payload Compression
Traffic Management and QoS
Caching
Recommendation
Boc (Branch office controller)can have traffic to destinations other than HQ on the same link, the preferred method is to enable payload compression on the IPsec tunnel between the branch controller and the master controller.
IP Payload needs to be enabled only between Aruba devices.
Notes
When this hardware-based compression feature is enabled, the quality of unencrypted traffic (such as Lync or Voice traffic) is not compromised through increased latency or decreased throughput.

They didn't do the NVIDIA test on it? At this point I guess it really doesn't matter. It sounds like it needs a new logic board, which has the GPU soldered on it. Price-wise, it's not worth having Apple put a new LB in it, given its age. If you're handy inside a laptop, you might consider installing a used LB yourself if you can find one on eBay, etc. Not good news, I know.

What are the essential cases where we must have use update module F.M.

Dear sap Friends ,
I want to update or insert bill no. in a ztable when creating bill through VF01 .
I have done it through insert sql query as well as by update module enabled functin module .
what are the essential cases where we must have to use update module enabled functin module and why we use IN UPDATE TASK .
mainly i want to know in which case i must have to use update module enabled functin module and not by insert or modify query used smply .
Thanks ,
Amit Ranjan .

Hi Amit,
I sincerly advice you to search SCN or any anywherelse as big theory is behind this
few related info.
If you are using more than one screen to collect the data to update a perticular table and corresponding underlying table Child table in that case , after every screen change an implicit data base commit takes place and you are still collecting the data from other screens , in such cases you use IN UPDATE TASK
Please go through SAP LUW

What's the business case for using adobe forms for handling print forms

Hi
We are just starting our SAP project and are looking at the possibility to use Adobe forms for generating and printing our forms, like purchase orders, invoices etc.
My Question is:
1. Is this possible / adviseable ?
2. if so - what's the business case in using Adobe forms - <i> We have been looking on the SAP Pricing for adobe interactive form, and in our point of view it's grotesque high</i>
3. What other options do we have - do we need to settle with SAP Script / Smartforms ?
Regards
Morten Nielsen

Hi Morten,
1. Is this possible / adviseable ?
As far I know SAP is going to stop support for SAPScript in coming years (I don't know exact dates). It is pretty much advisable to use Adobe Print Forms.
2. if so - what's the business case in using Adobe forms - We have been looking on the
SAP Pricing for adobe interactive form, and in our point of view it's grotesque high
We can use Adobe Print Forms where ever we can able to use SApscripts/PDF print Forms.
3. What other options do we have - do we need to settle with SAP Script / Smartforms ?
It is better to settle with Adobe forms rather than using SAPscript/Smart forms. One of the main reason for this is maintainance is much easier than SAPscript/Smart forms.
But remember that Java Stack need to be installed in order to use Adobe Forms.
Please visit the below SDN area on Adobe forms for more details.

at the moment it is all i've got.
i am going overseas in 3 days and don't have time to order a case from the internet, and the shops don't carry them yet.
i'll try and pick one up when I am travelling, but for now this is all I can use.
How do I clean it?

What tools does Microsoft use to mock UI interfaces, flowchart, use cases, and UML diagrams?

I have searched google, but was not able to find article or blogs to answer this question. The questions asked here are very old. So I think this is a very relevant question today.
We are a .NET group and we to update how we storyboard our application development. What tools does Microsoft use to mock UI interfaces, flowcharts, and use cases? Specifically for projects that are either C# .NET MVC 5 and above (looking forward to
vNext).
In the past, power point was able to do some of these things, but it seems it has been deprecated? Does Visio use these things? Also, is Visual Studio's 2013 UML diagram any good or is there another tool in Microsoft's bag of goodies that has more options?
I have read about blend, but it does not seem to be .NET MVC specific.
Again, this is asking about what tools Microsoft teams usually use to storyboard as our team would like to mimic the more contemporary processes. We are in the process of upgrading our .NET applications and feel it is time to update our workflow process
as well.
Any book recommendations on TFS 2013 and agile are welcomed as well.

What is the use of Data packet dim with Virtual cube with services

Hi Friends,
Could anybody tell me what is the use of Packet dimension in Virtual cube with services , It cannot contain data persistently ,Just fetch at runtime,Then there is no Physical load happening,Then why it should be automatically created for this??
Message was edited by: Pradeep choudhari

Hi Maik,
Unit dimension will not be created automatically until and unless you have keyfigure referning units..
But my question is : Why should we have data pack dimension , which is useless in this case of Virtual cube with services.It should not be created automatically!! What do you say??

Kisight:- If I Don't Have or Want to Use My iSight What Can I Use ?

kisight:- If I Don't Have or Want to Use My iSight What Can I Use ?
Or What Cameras are available for Macs ?
This question used to come up for Macs that did not have Internal Cameras and the User did not have an External iSight.
Since the advent of Intel Mac and the Internal iSight and OS 10.4.9 (late Tiger) the question has broadened from "What can I use with iChat ?" to "What cameras can I use with My Mac ?" and from there into the current Question this User Tip plans to answer.
On the whole it is a case of matching a camera for the type of application you are going to use it most with.
A web cam can be used in iMovie to create Email or Video Blogs although Camcorders do a better job. Camcorders can be used as web cams.
Camera Types
These fall into three main categories that themselves have subsets.
Your choice is going to be influenced by the Applications you want to use it with.
1) Firewire Cameras (Plug an Play)
a) The iSight (External) made by Apple and several other similar cameras have mostly disappeared off the market. (Although iSights seem to be still doing well on Ebay - See Version and Mounts).
b) Firewire Camcorders. These vary as to which apps that work with dues to the different Signal outputs they can do.
Apple Article TA26556 Highlights some that have issues due to their proprietary DV Format.
2) USB 1.1 able Cameras. (Not Plug and Play)
This includes most cameras pre Vista (more on that later)
Most of these will need a suitable Mac Driver either from the Manufacturer or from one of two Generic sources (macam and IOXeperts). Some manufacturers will include a Mac Driver on the CD that comes with the camera some will supply it as a download from their Site.
It is worth while saying at this point that iChat will also need this reasonably cheap iUSBCam Utility as well.
This Utility was originally designed for getting the External iSight to work on computers less than the G3/600Mghz spec for iChat. Then it included the ability to get USB cameras to work with iChat.
You will need one of these three options listed so far if you are OS 10.4.8 or below or have only USB 1.1 ports/sockets on your Mac.
3) USB 2.0 Cameras. (Plug and Play in most cases)
a) Those that are UVC (USB Video Class) Compliant (Also listed as Vista Certified)
Apple added a UVC driver to the OS at 10.4.9 but your Mac also has to have an USB 2.0 port that you can plug such a camera into (Some keyboard ports are not USB 2.0). This means that the camera is Plug and Play although it may not have all the features it has on a PC
b) Those that are USB 2.0 but are not Vista Certified/UVC compliant. (You are going to need Mac Drivers again)
This site about Apple Compatible cameras may be of some help.
A Note on quality of Pictures.
Firewire cameras of either sort are best with Camcorders being the best of all. (Generally more pixels delivered faster to your Computer)
The Newer USB 2.0 cameras are tending to exceed the 640 X 480 pixels that earlier USB1.1 cameras use with some currently giving 1.3Mp resolutions. It should be noted though that not all applications will use this format.
Look closely at the maximum Frame rate (fps) a camera can produce. You may not get it is every applications but something that starts with a max of 15fps is going to give you no leeway.
Applications
You may get some more insight into what to go for by asking in one of these forums:-
iSight Discussions,
iChat AV Discussions for iChat 3 and iChat 2 and Earlier,
iChat and iChat Sharing (in Leopard)
and iMovie Discussions
Please Note:- some of these are Category Links and you have to select a forum within the list at the top of the linked page.

Versions and Mounts Which Version Am I Buying ?
First off I will not say so much on Buying a second hand External iSight other than making sure you use a reputable Selling site or an Individual Seller so that you have recourse if the device turns out to be faulty. Try and get to see the camera working if you can, preferably seeing it plugged in and working or by iChat and seeing the Pic it produces (Get the person to show you live Screen shots (or Screen Share in Leopard/iChat 4) of System Preferences > Sound > Input as the iSight will be listed)
What I will list here is info about the different versions.
There were three versions before the External iSight was discontinued. There is little outward differences as the main change is the mounts that are included with each version. They all function the same way.
The versions are distinguished by letters (Revision A, B or C) in addition to the base part number and an added slash (M8817LL/).The Last model included different mounts for Laptops, Desktop Stand, Magnetic mount and one for a Flat Panel iMac (the Lampshade one). See pictures in this PDF on page 6.
Apple no Longer sell the External iSight or the Apple M9314G/B iSight Accessory Kit either but you may find it at other places as well if the mount you want/need does not come with the camera. Pics of Box and Contents
It appears that individual iSight mounts and other items can be purchased though this iSight Service FAQ page
Remember the youngest External iSight is likely to be at least 4 years old. Current anecdotal information suggests the cost of an Apple Repair to a faulty External iSight exceeds the cost of a USB Replacement (Or the value in real terms, of the camera itself - although higher prices seem to be quoted on Ebay and Amazon)

Thanks Nubz
I will review further an correct myself.
The last reads the way I meant as in physically getting to see it.
I am not sure you are reading it the same way.
As a consequence your suggestion seems a bit ambiguous to my mind.
Thanks for the input. I will read a digest context a bit more and see if I can rephrase.

What is best use of 1400 gb SGA (2 rac nodes 768gb each)

currently using 11.2.0.3.0 on unix sun sever with 2 RAC nodes each 8 UltraSPARC-T1 cpus (came out in 2005) four threads each so oracle sees 32 CPUS very slow(1.2 gb). Database is 4TB in size on regular SAN (10k speed).
8gb SGA.
New boss wants to update system to the max to get best performance possible Money is a concern of course but budget is pretty high, Our use case is 12-16 users at same time, running reports some small others very large (return single row or 10000s or rows). reports take 5 sec to 5 minutes, Our job is get the fastest system possible, We have total of 8 licenses available so we can have 16 cores. We are also getting a 6tb all flash SSD array for database. we can get any CPU we want but we cant use parallel query server due to all kinds of issues we have experienced (too many slaves, RAC interconnect saturation etc, whack-a-mole). sparc has too many threads and without PS oracle runs query in single thread.
we have speced out the following system for each RAC node
HP ProLiant DL380p Gen8 8 SFF server
2 Intel Xeon E5-2637v2 3.5GHz/4-core cpus
768 gb ram
2 HP 300GB 6G SAS 15K drives for database software
this will give us total of 4 Xeon E5-2637v2 cpus 16 cores total (,5 factor for 8 licenses) and 1536 ram (leaving ~1400 for sga). this will guarantee an available core for each user. we intend to create very very large keep pool around 300 gb for each node that will hold all our dimension tables. this we hope will reduce reads from the SSD to just data from fact tables.,
Are we doing a massive overkill here? the budget for this was way less than what our boss expected. will that big an sga be wasted will say a 256gb be fine. or will oracle take advantage of it and be able to keep most blocks in there.
will an sga that big cause oracle problems due to overhead of handling that much ram?

Current System:
===========
a. Version : 11.2.0.3
b. Unix Sun
c. CPU - 8 cpus with 4 threads => 32 logical cpus or cores
d. database 4TB
e. SAN - 10k speed disk drives
f. 8gb SGA
g. 1.2 gb ??
h. Users --> 12-16 concurrent and run reports varying size
i. reports elasped time 5 sec to 5 mins
j. cpu license -->8
Target System
===========
a. Version: 11.2.0.3
b. HP ProLiant DL380p Gen8 8 SFF server
c. RAM --> 768 GB
d. 2 HP 300GB 6G SAS 15K drives for database software
e. large keep pool -->90 gb to hold all dimension tables.
f. SSD to just data from fact tables
g. SGA -->256gb
Reassessment of the performance issues of current system appears to be required.Good performance tuning expert is required to look into tuning issues of current application by analyzing awr performance metrics . If 8GB SGA is not enough,then reason behind so is that queries running in the system are not having good access path to select lesser data to avoid flushing out of recent buffers from different tables involved in the query. Until those issues are identified , wherever you go, performance issue wont be going away as table size increase in future , problem will reappear.Even if the queries are running with more FULL Scan , then re-platforming to Exadata might be right decision as Exadata has smart scan , cell offloading feature which works faster and might be right direction for best performance and best investment for future.Compression (compress for OLTP) could be one of the other feature to exploit to improve further efficiency while reading the lesser block in lesser read time.
Investment in infrastructure will solve a few issue in short term but long term issue will again arise.
Investment in identifying the performance issues of current system would be best investment in current scenario.

What is the use of Storage loc.ref.in LE-WM Interface to Inventory Managemt

Hi Guys
What is the use of below fields
Special movement indicator for warehouse management and Storage loc. ref.
In the WM configaration LE-WM Interface to Inventory Management
How we can do the below scenario with this configaration
I have 3 scenarios all scenarios have MIGO and placing stock to WM
2 scenarios requres Immediate TO creation after MIGO 101 mvt type
But last scenario does not want Immediate TO ,it is having another Z transaction to create TO
But problem is for the last scenario also creating Immdiate TO after MIGI 101
How to avoid this Immdiate TO for this scenario
And How to allow it for first 2 scenarios
How we can to with that configaration

Hello ,
It is not possible directly in customising as all three cases are using the same Mvt Type.
Alternate Solution :
You may try an by creating a new Mvt Type 901 i.e making a copy of 101.
Thereafter try to link a new Ref Mvt Type to the same .You should use this case for the third scenario.
This may resolve your problem.

i am waiting for u r replies.
Thanks & Regards,
Kishore.

Hi,
'The provision account is only required if there are conditions that are relevant for accrual, for example, rebate conditions. If this is the case, account determination takes place in the billing document with the field'
In other words it will be used to store the valuue of a( for eg.,Rebate) condition type in a different GL a/c for the periodic calculation of the total value of the same cond.type...

What is the use for CREATING VIEW WITH CHECK OPTION?

Dear Legends,
I have a doubt
What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.
A: Enforcing constraints at DB level.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???
Please clear my doubt's Legends
Lots of Thanks....

Karthik

Hi, Karthick,
karthiksingh_dba wrote:
... What is the use for creating view?
A: First Data Integrity, Selecting Particular Columns..Most views are created and used for convenience. A view is a saved query. If the same operations are often done, then it can be very convenient to code those operations once, in a view, and refer to the view rather than explicitly doing those operations.
Sometimes, views are created and used for security reasons. For example, you many want to allow some users to see only certain rows or certain columns of a table.
Views are necessary for INSTEAD OF triggers.
What is the use for creating a view with check option?
A: As per oracle manual I read that its a referential integrity check through views.The reason is integrity, not necessarily referential integrity. The CHECK option applies only when DML is done through the view. It prohibits certain changes. For example, if a user can't see certain rows through a view, the CHECK option keeps the user from creating such rows.
A: Enforcing constraints at DB level.I'm not sure what you mean. Please give an example.
A: using CHECK OPTION we can do INSERTS UPDATES for a view for those columns who have no constraints... is it right??No. Using CHECK OPTION, you can do some inserts and updates, but not others. The columns involved may or may not have constraints in either case.
A: If we do a INSERT OR UPDATE for columns who have constraints it will show error... is it right???If you try to violate a constraint, you'll get an error. That happens in views with or without the CHECK OPTION, and also in tables.

What is a use case?
