What is the difference between relational database and NoSql DB

HI,
i never work with any nosql db. so i like to know What is the difference between relational database and NoSql DB ?
in relational db sql server we can create relation between table by PK and FK. so is it possible in NoSql db like Mongo db ?
sql server db use to in big data for any organization. does Mongo db like nosql db use for same purpose ?
i like to know in what kind of situation people use Mongo db or any NoSql db. please tell me few sample scenario where people like to use Mongo db or any NoSql. thanks

Here are some good links that describe the differences:

What is the difference between alter database and alter tablespace?

Hi
I was searching for the difference between these 2 commands and have gotten not much conclusive result. Can anyone enlighten me on what is the difference if I were to use ALTER DATABASE OPEN READ ONLY compared to ALTER TABLESPACE x READ ONLY?
My objective to is control, such that sometimes users can edit the database, and other times, not possible to do so.
Thanks in advance.
wy

Hi,
A database can be made with more than one tablespace.
You can have a table called A into a tablespace TSA and a table called B into a tablespace TSB, then if you use ALTER DATABASE OPEN READ ONLY any tablespace can be writen, but if you use ALTER TABLESPACE A READ ONLY, you can't write, insert into table A because it is read only, but you can write, insert rows into the table called B because the tablespace B isn't read only.
You need to do ALTER TABLESPACE B READ ONLY to deny the inserts into table B.
You should do this for all tablespace that make the database.

What is the difference between standard,sorted and hash table

<b>can anyone say what is the difference between standard,sorted and hash tabl</b>

Hi,
Standard Tables:
Standard tables have a linear index. You can access them using either the index or the key. If you use the key, the response time is in linear relationship to the number of table entries. The key of a standard table is always non-unique, and you may not include any specification for the uniqueness in the table definition.
This table type is particularly appropriate if you want to address individual table entries using the index. This is the quickest way to access table entries. To fill a standard table, append lines using the (APPEND) statement. You should read, modify and delete lines by referring to the index (INDEX option with the relevant ABAP command). The response time for accessing a standard table is in linear relation to the number of table entries. If you need to use key access, standard tables are appropriate if you can fill and process the table in separate steps. For example, you can fill a standard table by appending records and then sort it. If you then use key access with the binary search option (BINARY), the response time is in logarithmic relation to
the number of table entries.
Sorted Tables:
Sorted tables are always saved correctly sorted by key. They also have a linear key, and, like standard tables, you can access them using either the table index or the key. When you use the key, the response time is in logarithmic relationship to the number of table entries, since the system uses a binary search. The key of a sorted table can be either unique, or non-unique, and you must specify either UNIQUE or NON-UNIQUE in the table definition. Standard tables and sorted tables both belong to the generic group index tables.
This table type is particularly suitable if you want the table to be sorted while you are still adding entries to it. You fill the table using the (INSERT) statement, according to the sort sequence defined in the table key. Table entries that do not fit are recognised before they are inserted. The response time for access using the key is in logarithmic relation to the number of
table entries, since the system automatically uses a binary search. Sorted tables are appropriate for partially sequential processing in a LOOP, as long as the WHERE condition contains the beginning of the table key.
Hashed Tables:
Hashes tables have no internal linear index. You can only access hashed tables by specifying the key. The response time is constant, regardless of the number of table entries, since the search uses a hash algorithm. The key of a hashed table must be unique, and you must specify UNIQUE in the table definition.
This table type is particularly suitable if you want mainly to use key access for table entries. You cannot access hashed tables using the index. When you use key access, the response time remains constant, regardless of the number of table entries. As with database tables, the key of a hashed table is always unique. Hashed tables are therefore a useful way of constructing and
using internal tables that are similar to database tables.

What's the difference between segment filtering and reduced message type

Hi gurus,
What's the difference between segment filtering and reduced message type? It seems they have the same functionality: Reduce the segment while idoc is generated.
Thanks in advance.

Hi,
BD53 is for IDoc Reduction.
this allows you to create a reduced message based upon a standard message type.If you want see mandatory fields. go to T-coe BD53 and give one standard messege type name and eg: matmas
there mandatory fields will be in Green color..
And BD56- This transaction is used to filter out segments of IDocs for combination of sender and receiver. This is usefull in scenarios where a standard IDoc with many segments is used but the receiving partner is only interested in some of the segments
the table related to this transation is TBD20
please go through below blog you have an idea abt that,

What's the difference between "controlfile autobackup" and "snapshot contro

Hi All,
What's the difference between "controlfile autobackup" and "snapshot controlfile" in RMAN configure ? Both are controlfile backups, what the difference between the controlfiles they backup ? Why there are two of these options ?
thanks

RMAN creates a control file snapshot to perform catalog resync operations. Control file autobackup will automatically create a backup of the control file whenever there are database structure changes.

What's the difference between reguler KDE and KDEmod?

Hello all,
In two weeks I get my new laptop, which will be capable of running Arch and KDE ( as my current computer isn't, somehow it only runs Fedora w/ Gnome)
Since I really like Arch and already got it working on Virtualbox, I want to install it on my new laptop. I'd like to get it working with KDE, but I noticed Arch also has KDEmod. I already searched the forums but couldn't really find an answer to my question: What is the difference between regular KDE and KDEmod and which one is better for me to use?
Thanks in advance!

Allan, i forgive you for your poor paragraph construction and sorry for me being a bit peeved
However, i know you have read more from the IRC log than just that one sentence by me...
Allan wrote:
From the IRC log, I do not think that conclusion is too far off, especially if you are considering Arch-Stable as your base... So saying "plain wrong" seems... well... plain wrong. Especially given the irc log:
<funkyou> in one sentence: to do what we really want to do, we need a stable platform.
So why not showing the whole picture and clear this up:
<funkyou> ok, to start: i think at least some of you have noticed that arch linux is a fine platform for what we want to deliver, but there are some little "annoyances"
<funkyou> mainly:
<funkyou> -.so bumps every few weeks
<funkyou> -the general "freshness"
<funkyou> -a lot of manual interaction needed (sometimes)
<funkyou> everyone can see these problems when looking at the forums, _most_ of them are related to updates
<funkyou> in one sentence: to do what we really want to do, we need a stable platform.
Makes more sense now? Its not that Arch is too unstable, its just that we cant keep up will all the changes... And this is not Archs "fault" nor anyone elses fault, its just going too fast for us. Most annoying or severe bugs in our tools are there due to upstream updates. And the reasons are not really the .so bumps (which are mostly solved by a simple rebuild) but also constantly changing apis and stuff. This is not a big problem in KDE (they keep their apis clean), but a big one when it comes to other stuff like parted, to give an example. And this is our main problem, we need to constantly adapt our code to upstream changes.
This even resulted in a repo with modified or "frozen" Arch packages just to keep our liveCD going, and now we are looking for solutions for this problem, and "stable" snapshots seem to be one way... Oh, and if we would do this (there is nothing announced yet), we would do our own snapshot every X months because ArchStable seems to be a dead project. We also considered cooperating with the ArchServer guys, but their stuff is really made for servers, so even while their project is really nice its not really an option for us.
Well, we'll see what we will do during the next months, now we are still testing and evaluating some solutions... Oh, and people, please stop any "we dont need another ubuntu" complaints...

What is the difference between undo tablespace and online redo log files.

what is the difference between undo tablespace and online redo log files. I am confused
as per my knowledge undo tablespace is used to store the undo information when a table is being updated so that, just incase we need to rollback a transaction we know what was present in the table earlier.
when a transaction fails the SMON performs the rollback of the data.
This undo data is stored in the undo tablespace and read consistency if any is enforced.
is my understanding till here correct?
Now, can this undo data/before image not be stored in the redo log buffer and online redolog files?
can redo-log files not store this information?
in fact, is it that when undo tablespaces exist in a database, the undo data/before image is stored in both the undo tablespace and also the redo log files?
kindly clarify my doubt.
thank you.

This question has been asked many times before. The answer is always the same.
Yes, redo contains the before image of data (and the after-image). Therefore, it **COULD** be used to roll back a transaction.
BUT... Redo is written sequentially. Using it to rollback your transaction would involve reading through all the redo written by maybe thousands of other people. It would be painfully slow.
Your transaction is, however, directly linked to just the UNDO that it generates (which is JUST the before image of the data). So, your undo is your undo and doesn't share space with anyone else's undo. Therefore, using it to roll back YOUR transaction is fast.
The fact that undo is only the before image of the data also makes it faster than wading through a sea of before and AFTER images as you'd find in redo. About twice as fast, in fact, since there's half the data. Roughly.
Redo also gets written and flushed to disk whenever there's a commit, 3 seconds are up or too much (1MB, actually) redo gets generated between flushes caused by other factors. Your redo gets flushed when those things happen, even if you haven't actually committed your transaction. And redo logs recycle themselves, meaning that your redo -even if your transaction hasn't been committed yet- can be over-written by later transactions. Try rolling back when that's happened, if redo was the source of your rollback data!
Undo, however, cannot be over-written if the transaction has not been committed. Ever. If you don't commit for three years, there will be three years' undo stored in your database (assuming you had the space, of course!).
I could go on, but that will do. Redo is there fore RECOVERY, after catastrophe. Undo is there for read-consistency (and the occasional change of mind). Two different functions. Two different mechanisms. Each one highly tuned to doing what it does, why it does it, most efficiently and effectively.

What is the difference between FND_CONC_CLONE.setup_clean and target_clean

What is the difference between fnd_conc_clone.setup_clean and fnd_conc_clone.target_clean?
I always run setup_clean to wipe out all the information carried from source, and then run adautocfg.sh on dbTier followed by appsTeir. This will give me the clean newly cloned ebs system. But what is target_clean for? What is the difference between setup_clean and target_clean;
James

I finally go through the code and actually run the target_clean in our test system. Here is general rule, if you clone the ebs system, you only need to run setup_clean, it will clean out topology information or ebs connection information from the system. Then you run adautocfg.sh on db tier first following by adautocfg.sh on apps tier. All the topology or connection information will be populated again inside the database.
Once you have cloned the system, you do not want any printer setup info, log/out info or profile info carried from source, then you can run target_clean. For me, I do need preserve printer and profile info, so I need to export following 4 tables before running target_clean.

FND_PRINTER,
FND_PRINTER_TL,

(261680070) Q WWO-13 What are the difference between WLS6.1 and WLS7.0 web services?

Q<WWO-13> What are the difference between WLS6.1 and WLS7.0 web services?
A<WWO-13> The differences are huge, so different in fact that 6.1 web services cannot
be deployed in 7.0. WLS7.0 and Workshop have much greater functionality than the
limited stateless session (RPC-style) and JMS destination (MSG-style) approach of
6.1. Workshop web services can interact with any type of EJB, any JMS destination
as well as other web services and directly accessing databases. The framework for
building the web service is better and more adaptable and Workshop provides a fully
integrated develop, deploy, test and debug environment. Additionally, WLS7.0 have
the capacity to be much better at performance since due to XML parser enhancements
and the addition of XML maps.

If you want to take existing WLS6.1 web services and convert them to WLS7.0 you can
do so quite easily. The WLS7.0 Ant still supports wsgen so you do not need to even
change your build.xml file. The generated web service however will be implemented
is a manner compliant with the WLS7.0 environment. More details are at:

What is the difference between physical topology and network topology ,

HI
what is the difference between physical topology and network topology ,
adil

They are tightly linked. The network topology is only interested in the networking links between servers or other actors. A physical topology contains the servers as well as the networking components between them. You might use the term in a different
manner which related to various site's physical attributes such as location but I doubt that's what the document you're working from means.

What is the difference between full checkpoint and incremental checkpoint?

What is the difference between full checkpoint and incremental checkpoint?
And what is checkpoint queue?
Can someone clarify these concepts?
Thanks!

Hi,
there are different types of checkpoints:
- Full checkpoint:
=> DBWR writes all dirty buffers from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- can be triggered by different events, like a logswitch, a manual checkpoint (alter system ..), a shutdown and so on
This is the setup point for SMON for a crash recovery.
- Partial checkpoint:
=> DBWR writes all dirty buffers of a singel tablespace from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- can e triggered by an ALTER TABLESPACE OFFLINE, ALTER TABLESPACE READ ONLY, ALTER TABLESPACE BEGIN BACKUP statement.
Incremental checkpoint:
number to all file headers and the controlfile.
-- can be triggered by different events, like a logswitch, a manual checkpoint (alter system ..), a shutdown and so on
- Partial checkpoint:
=> DBWR writes all dirty buffers of a single tablespace from the Buffer cache to the datafiles and CKPT retrieves a new Checkpoint Change Number from a sys owned sequence and writes this number to all file headers and the controlfile.
-- frequency is determined by FAST_START_MTTR_TARGET parameter (new feature to Oracle 9i), with wich you can specify a time in seconds which SMON is allowed to take maximal for a Crash Recovery until the database must be open again.
Dapending on the system you have SMON must calculate the maximum number of Redolog-blocks which it can manage to recover in the specified number of seconds. It will then create so called incremental checkpoints which will be tracked in the so called checkpoint queue in memory.
FAST_START_MTTR_TARGET is auto-tuned in Oracle 10g and Oracle tries to manage (incremental) checkpoint in a fashion that a minimum of I/Os are caused and a minimum time for crash recovery is needed.
If you set LOG_CHECKPOINTS_TO_ALERT to TRUE you will find checkpoint information in the alertSID.log file. You will see FULL and INCREMENTAL checkpoints then.
Hope this clarifies your question,
Lutz Hartmann

What is the difference between Grid computing and Cluster ?

Heh Friends
What is the difference between Grid computing and Cluster ?
/sumit

You
can't easily switch a server from being a database
server into an application server when the load on
your system changes.
That's only because you didn't architect your grid that way. :P
(Mine doesn't do that either)
>
I guess people use the bits of the definitions that
support their marketing claims :)
Isn't that the truth!
Oracle marketing speaks of grid as a concept with their technologies enabling the grid. Other companys offer products that turn computers into (their defintion of) a grid - Sun's Grid Engine, Avaki's Grid, and Platform's LSF come to mind.
Gotta love the marketing folks; especially at Oracle. It seems to me that when a product doesn't succeed, they tend to rebrand and reintroduce.

Hi,
Upgrade SAP or Installation of SAP R/3 and ECC
What is ECC? Where to find the installation steps of ECC 5/6.0 with SQL as database and on windows platform with the steps including Solution Manager installation?
http://service.sap.com/instguides
ECC means Enterprise Central Component.
There are all the relevant installation guides. You NEED SAPNet access because without a registered and licensed SolMan installation number you will not be able to generate the SolMan key for the ECC installation.
Upgrade to 4.7
Have you gone through an upgrade to 4.7?
What are the difference or changes associated with 4.7.
If you are currently on 4.6C and are inching forward to upgrading to 4.7 then this information might be useful to you.
There is very little difference between 4.6 and 4.7, the only "steps" you should need are steps in SU25 ( skip step 1) Then go through all your role and perform a merge old new to bring in the new authorization objects
Just to forewarn you of a potential problem which have been encounter at the point of writing.
After updating/ modifying roles in step 2C, when going back into 2C to make sure all roles are now green, 70% have gone back to red!
The maintenance done is ok, but there seems to be a problem while trying to go back into the roles again to re-generate.
SAP recognizes them as needing "adjustment", so you cannot pick them up in mass generate in PFCG as they do not come in, even though the authorizations tab is red.
This problem is currently with SAP and it is confirmed that nothing have been done wrongly.
Generally, the work is quite manageable in the upgrade, but don't be surprised at how big the upgrade is when compared to upgrading from 46b to 46c.
If we have full software of 46c and 47E is it possible to upgrade 46c to 47E or there is a seperate 47E upgrade software need to be requested from SAP?
Where I can get the document with upgrade steps on the service market place?
It is of course possible and supported:
http://service.sap.com/inguides
--> SAP Components
--> SAP R/3 Enterprise
--> (choose your version)
at the bottom there is an "Upgrade guide" for Windows and Unix.
For Upgrades it is recommended to read ALL the notes mentioned in the
upgrade guide and to make sure one is using
- the correct version of the "tp" program
- the correct version of the "R3trans" program
- the correct version of the "R3up" program
All that is explained in the upgrade guide and in the corresponding notes.
If this is your first upgrade you should take a person, that has some experience on doing that for the first time.
Installation of SAP R/3
Currently we are going to install SAP on a new IBM server from the existing COMPAQ server. Where can I get the steps for that.
Configuration is :
   OS - windows 2003 server
   DB - Oracle 9i
   SAP 4.7
http://service.sap.com/instguides
--> SAP Components
--> SAP R/3 Enterprise
--> SAP R/3 Enterprise Core 4.70 / Ext. Set 2.00 (SR1)
--> Inst. Guide - R/3 Enterprise 4.7 x 2.00 SR1 on Win: Oracle
The above url is the SAP Service Marketplace with all the information you need to install, configure and run system. You need to be a valid licensed customer with a user ID and PASSWORD to use that.
Without access you won't be able to successfully run any SAP systems because it has notes, patches etc.
