Difference between Zfs volume and filesystem ?

Hi,
Does any one know the difference between Zfs volume and Zfs filesystem?
On one of the existing nodes i saw the following enries for two times....

For most users, a volume isn't normally necessary except for 'dump'.

Disk Utilty - what is difference between single volume and single partition

In Disk Utility I can, should I wish, format a drive by using Erase to create a single volume. Also in Disk Utility, I have the option to use Partition to create one (or more) partition.
What is the difference between a volume and a single partition?
What are their relative merits?
In what circumstances would I want to create a single partition instead of a volume?
Disk Utility also prompts me to name the volume or partition. From experience, what would you suggest as a suitable name and where is this information subsequently used?

A "volume" or "partition" are the same thing. The subject of using partitions has been covered many times on the forums. Do some searching and you'll find quite a lot of information. Also try doing some Google searching.

What is the difference between audio volume and audio loudness?

Hi to all,
While trying to pep up sound levels to my audio clip, I found these two parameters which could enhance the sound levels...volume and loudness. Can anyone please tell me the difference between these two?

I clicked on the triangle at the left edge of the audio clip and went into the audio enhancement window where loudness parameter can be adjusted. Clicking the 'go back' button at the top left edge of this panel gets you to the audio panel where you can adjust the volume, pan etc. [dunno what panning means]!
Yea, I too thought that these two meant the same before I observed these two options.

Hi I have the old photo shop elements 10 on my computer and want to update and was wondering what the differences between photoshop, lightroom and photoshop elements are?
Also when I upgrade does it have to be with a monthly membership or can I just purchase the product out right like you use to be able?

You cannot "update" from what you have to any of the applications you mention. It will have to be a straight purchase or subscription at full price.
Photoshop is a professional level application that makes no apologies for its very long and steep learning curve.
Lightroom is all about volume, and very light editing.

What's the difference between "tar" command and ufsdump?

what's the difference between "tar" command and ufsdump?

Conceptually they do much the same thing.
Except ufsdump is only for ufs filesystems and since it is able to use deeper knowledge of the internals gains some performance.
ufsdump is multithreaded for example.

Difference between UUID: DocumentID AND UUID:InstanceID

Hi All,
         This is my first query in this forum. Hope I am into the right location.
          Can anyone please tell me what is the difference between UUID: DocumentID and UUID:InstanceID? AND
           Based on what properties these ID's will be created?
   Your immediate reply is highly appreciated.
Thanks in advance and Regards,
Adobe User.

It appears FAT's and NTFS's UUIDs are not true UUIDs, whatever it means :)
All Linux filesystems support filesystem UUIDs; FAT and NTFS filesystems don't support true UUIDs, but are still listed in /dev/disk/by-uuid with a unique identifier
http://wiki.debian.org/Part-UUID#Via_UUIDs
Also, I'm trying to comprehend how LVM and LUKS fit into the picture... As far as I can tell, they are not filesystems, like ext4 or ntfs. They are transparent containers. The data itself are stored inside these containers. Containers are basically responsible for knowing how to get the data. Therefore, how come LUKS can support LABELs? I thought LABELs are part of a filesystem, aren't they?

Difference between ZFS checksum algorithms

Hello all.
Where i can find information about differences between fletcher2, fletcher4, and sha256 algorithms for ZFS checksums?
Thank you.

You should learn to use google. First hit on "zfs checksum algorithms" gave me:
http://www.opensolaris.org/os/community/zfs/source/;jsessionid=2686F92391554A5B939B93197A2B443C
In short: at the moment only 1 algorithm can be used, it wouldn't surprise me if the others haven't been fully implemented yet and that would mean that there are not much differences since you only have 1 option to use right now.

Difference between Simple maintanence and Export mode and Organisation plan

Hi all,
Can any one please explain the difference between Simple maintanence and Export mode and organisational plan in SAP easy access.
Thanks & Regards,
Naga

Expert Mode Infotype Maintenance: This interfaces allows you to edit individually selected objects in OM (Org Units, Positions, Jobs) via infotypes.
Expert Mode: Simple Maintenance Interface (PPOM_OLD) is used to quickly create a new Organizational Plan. As a user, you can pretty much maintain large volumes of data very easily ( i.e create several objects simultaneously), without having to go through the more "Performance Intensive" Org and Staffing interface.
In accessing the Simple Maintenance interface to create your org structure, the initial screen requires you to specify which evaluation path you want to create your org structure.
Organizational Plan: This is what provides you with a complete picture of an enterprise's environment. It comprises elements (objects like Org Units, Positions, Jobs etc) which are used as building blocks for creating an Organizational structure.
Need more information? Let me know.

Difference between Session method and call transaction

Hi,
please give me the differences between session method and call transaction,
briefly explaining synchronus , asynchronus, process, update.
Thanks in advance

Hi Vijay Kumar
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.
http://www.sap-img.com/abap/difference-between-batch-input-and-call-transaction-in-bdc.htm
Among the two methods call transaction is better compared to session bcoz data transfer is faster in it.
Differences between call transaction and session.
Session Method:
1) Data is not updated in the database table until the session is processed.
2) No sy-subrc is returned.
3) Error log is created for error records.
4) Updation is always synchronous.
Call Transaction Method:
1) Immediate updation in the database table.
2) sy-subrc is returned.
3)Error need to be handled explicitly.
4) updation can be synchronous as well as asynchronous.
2) ya u can use using the N mode no screen.
3)u can't handle multiple transaction in call transaction.
4) u can handle multiple transaction in session using the BDC_INSERT fm.
5)When u go to SM35 u can able to see the error records.
Which is best?
That depends on your requirement. Both of them have there advantages.
According to the situation u can choose any one of these.
difference between batch input and call transaction in BDC Session method.
1) synchronous processing.
2) can tranfer large amount of data.
3) processing is slower.
4) error log is created
5) data is not updated until session is processed.
Call transaction.
1) asynchronous processing
2) can transfer small amount of data
3) processing is faster.
4) errors need to be handled explicitly
5) data is updated automatically
For session method,these are the function modules to b used.
BDC_OPEN_GROUP
BDC_INSERT
BDC_CLOSE_GROUP
For call transaction,this is the syntax.
CALL TRANSACTION TCODE USING BDCDATA
MODE A or E or N
UPDATE A or S
MESSAGES INTO MESSTAB.
Take a scenario where we need to post documents in FB01 and the input file has say 2000 records (2000 documents, not line items in FB01 but 2000 records)
In the BDC call transaction method
We call the transaction FB01 2000 times (once for each record posting) and if the processing fails in record no 3 it can be captured and start with reocord 4.
Eg: Loop at itab.
call transaction FB01
capture errors
endloop.
In the session method.
We do not explicity call the transaction 2000 times, but all the records are appeneded into a session and this session is stored. The processinf of the session is done wwhenever the user wants it to be done. Hence the errors cannot be captured in the program itself
Check these link:
http://www.sap-img.com/abap/difference-between-batch-input-and-call-transaction-in-bdc.htm
http://www.sap-img.com/abap/question-about-bdc-program.htm
http://www.itcserver.com/blog/2006/06/30/batch-input-vs-call-transaction/
http://www.planetsap.com/bdc_main_page.htm
Batch Input Session method is asynchronous as told by others here. But the advantage of this is that you have all the error messages and the data for each transaction held persistantly. You don't have to code anything for processing them or writing the logs.
But at the same time, the same feature can be disadvantageous if you need to react to an error or if there are too many errors to manually correct in a session. Since the session are created in the program and its execution is done seperately, you loose the trackability of such transactions.
With a call transaction, what was a disadvantage above will become an advantage. Call transaction immediately gives you messages back and you can react to it in your program. But the disadvantage is that, if you have several hundreds of transactions to run, running them from within the program can be resource crunching affair. It will hamper the system performance and you cannot really distribute the load. Of course, you have some mechanisms with which you can overcome this, but you will have to code for it. Also, storing the messages and storing the errored transaction data etc will have to be handled by you in the program. Whereas, in batch input session, your program's job is to just create the session, after that everything is standard SAP system's responsibility.
Ideally, you should do a call transaction if the resources are not a problem and if it fails, put the errored transaction into a session.
You can decide based on the data volume that your BDC is processing. If data volume is high go for session else call transaction will do.The call transaction updates will be instantaneous where as session needs to be processed explictly after creation.
Session Method
1) Session method supports both small amount of data aswell as large amount of data
2) data processing is asynchronus and data updation is synchronus.
3) it process multiple apllication while perfomaning validations.
4) in session method data will be updated in data base only after processing session only.
5) system provide by default logfile for handling error records.
6) it supports both foreground aswell as background process
in bdc we use FM ...
bdc_open_group " for creating Session
bdc_insert " adding transaction and bdcdata table for updating database
bdc_close_group " for closing Session
Call Transaction
1) Call transaction exclusively for small amout of data
2) it supports only one apllication while perfoming validations
3) there is no default logfile, We can explicitly provide logic for creating logfile for handling error records.
we can create logfile by using structure....BDCMSGCOLL
4) it doesn't support background processing.
5) data processing is synchronous and Data updation is Synchronous( default), in
this method also supports daya updation in asynchronus process also.
syntax:
Call transaction <transaction-name> using BDCDATA
mode <A/N/E>
update <L/A/S>
messages into BDCMSGCOLL.
BDC:
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

Difference between Mac Pro and Mac XServer

Hi,
I wanted to know if there is any difference between Mac Pro and the Mac XServer - at the OS level? Meaning, if I design an application on Mac Pro would it run seamlessly on XServer or do I need to care about a few things.
Please advise.
Thanks,
Abhishek

Both Mac OS X and Mac OS X Server are presently at the Tiger 10.4.10 release, with Mac OS X Server having various added pieces and features, and having a few structural and configuration differences.
* Do both of them support the ipv6 protocol
Yes; both Mac OS X and Mac OS X Server both offer IPv6.
* do both of them support LDAP and PAM based authentication
Mac OS X and Mac OS X Server have LDAP support, yes. Mac OS X Server has LDAP authentication, DNS and a variety of other servers built in. Mac OS X is configured as a client, though there is the Apache web server.
Haven't looked for PAM for either platform.
* Do both of them support the same level of Java ( I understand we need 1.5 or higher for Tiger / Leapord)
Java itself is the same on both Mac OS X and Mac OS X Server, though Mac OS X Server has server-oriented pieces of Java present. And it's still write once, debug everywhere.
No Leopard questions are permissible here at this time; Leopard details are NDA.
* Do the compilers (gcc) have different compilation options - maybe xServer uses some better optimized flags that handle large volumes of data and network traffic.
AFAIK, there are no differences in gcc defaults. Nor would I expect any. Handling volumes of data is left to the programmer. (I'm not even sure how a compiler author would even implement that sort of difference.)
* Is there any difference in the behavior of the way the libraries ...
I'd expect the exact same behavior the programmer requested would occur with both platforms.
Now as for what I expect is the root of your question, yes, you'll likely want to test your application on both Mac OS X and Mac OS X Server software platforms. There can exist very hard to predict details such as cases where dual NICs or the aforementioned directory differences that have tossed a few applications off the rails and into the weeds; have caused applications to fail.
You can choose to install Mac OS X Server on a Mac Pro. Probably the 10-client, because you probably aren't planning to serve piles of clients from the Mac Pro.
An overview of Mac OS X Server is here:
http://www.apple.com/server/macosx/specs.html
Now as to whether or not I would expect run-time differences, no. But I've been at this way too long and have chased way to many weird bugs to make any promises here.

Difference between Rebate rate and accrual rate

Dear Experts,
Can you explain the difference between Rebate rate and accrual rate in rebate processing ?
If possible, give any example so that it would be easier to understand.
Thnx in advance
regards,
Sagar

Hi Sagar,
I also agree that rebate is an amount which is derived from either sales order or billing doc.
No it's not; only billing documents update rebate agreements.
... two terms i.e. Rebate rate and Accrual Rate maintained in condition records for rebate agreement.
Accrual Rate = The rate used to accrue the value (provision) before settlement takes place.
Rebate rate = The rate used to generate the real credit amount to the customer when settlement takes place.
Usually both rates are set the same but, because if scales are used in the rebate rate, then it is usual to manually set the accrual rate at the expected rebate rate based on the planned sales volume.
If I am not wrong, the condition technique it it the accrual rate which determined not the rebate rate.
Not correct; the condition technique is used to determine both rates in the rebate condition.
Also i tried to create scales for rebate, this can be done with rebate rate and not with accrual rate. Then what is its use.
Scales are used when the amount is paid on a variable rate depending on the total customer consumption. The idea is that the more the customer is purchasing, the more rebate he will receive, also on its previous purchases.
Accrual rate is fixed (no scale).
Hope it helps.

What is the basic difference between Hyperion Planning and HFM

Hi GURU'S,
what is the basic difference between Hyperion Planning and HFM and when do we choose them.

On a high level the difference is this:
1. HFM is best for global collection (collecting data from scattered entities), group consolidation and for easily structuring financial reporting (mainly consisting of financial data)
2. Planning is best for modeling your business, starting from a demand forecast and arriving to capacity planning and finally to financial statements, by utilizing business drivers (non-financial data like volumes, prices, productivity rates etc)
Of course, differences may be analyzed at several levels down to technical, but the discussion may turn out to be too long, yet adding little value to the question: "when do we choose the one over the other". Bear in mind that your requirements may turn out that you need both.

Difference between maximum concurrency and batch mode in JDBC

Hi All,
Could som one tell me the difference between maximum concurrency and batch mode in receiver JDBC adapter?
Regards,
XIer

Hi,
The Max Concurrancy and Batch mode are used for performance tunning for JDBC adapter.
Max Concurrancy is possible upto 5 only. so even if you will be taking up 10 it will by-default take 5.
The number of records being processed depend on the size of each record. for e.g Per minit XI Is Processing 50 Records,It will Take lot of time to process all Records.
So if you set Max concurrancy as 5 then at time 5 messages will be processed simultaneously.
In Batch mode it will, collect the multiple SQL statements that will be created for records to be processed and processed at a time. It will improve performance considerably.
But Batch Mode is possible with only INSERT, UPDATE, DELETE etc.
The Stored procedures can be executed with max concurrency
Thus it completely depends that on the no of records to be processed at a time and volume of Mesasges.
Thanks
Swarup

Difference Between PI7.0 and PI7.1

Hi
Any one give me Differences between PI7.0 and PI7.1.
What are the major features Included in PI7.1
Thanks

Hey,
In specific there are lotz of new features adn goodies to be bundled with PI 7.1 scheduled for september release.
Levarage will be on SOA, performance enhancements, and addressing current problem that many of us face thatz high-volume message processing. is supported by message packaging.
Untill now we are only dealing with Integration Repository. PI 7.1 introduces Two components the concept of Enterprise Services Registry, Enterprise services Repository.
ES- Repository is based on Integration Repository but remember concept of messgae interfaces will be replaced by Service Interfaces.
SAP NW PI 7.1 the Enterprise Services Repository will offer multiple operations per service.
Significant enhancements in CCBPM like Driving WS-BPEL 2.0 standard,User Decisions,Extended conditions and expressions,BPEL4WS 1.1 standard adoption.
Additional Functions provided for mapping most imp one Synchronous DB/RFC look-ups.
Additional support for standards.
Even quite a few changes in Integration Directory:
XML PAYLOAD VALIDATION in Sender Agreement Validate incoming/outgoing .messages against XML schema.
As other have suggested https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/706005a3-3bd6-2910-91ae-a2016239bdcf wil give you a good insight to PI 7.1.

Don't know what it means.
Are you listening to the iphones speaker or through earbuds?
Is something blocking your speaker?
Is the volume turned up?
Have you tried a restart?
