Difference between capture schema and import/register schema

As far as versioning control, what are the differences, if any, between 1.) capturing a schema's objects thru design editor and 2.) importing and registering a schema?

Capturing a schema will create instances of the TABLE type in the Designer model.
Registration creates a new model with new types in the Repository.

How to export a schema and import the schema to a different schema name

I am using Oracle9i Oracle Enterprise Manager Console.
I can export the HR to a dmp file.
I have created another user call MYHR and I would like to import hr.dmp to the new user.
1. How can I add a schema using OEM?
I can do it by creating a table in MYHR and refresh OEM.
2. How can I import HR.dmp to MYHR using OEM.
I can import it using command line:
imp user/password@connectstring file='c:\hr.dmp' full='Y'
Any hints are appreciated

Hi,
1.
You don't have to create a schema explictly.
Say you create a user u1. Now this user u1 create some object s, then the schema u1 is automatically created.
Schema is actually a logical collection of objects.
2.
Why using OEM for importing. Using the command is much more easier.
Your command is bit incorrect. Don't use full=y to import a schema.
Use ; imp userid=user/password@connect_string file=filename fromuser=HR touser=MYHR
Better add "log=some text file". Then use can see the log also.

JSP - difference between extending class and importing class

In the following scenario
class A
private static String con;
Case 1
==========
class B extends A
Case 2
===========
import A;
class C
A objA = new A;
What will be the difference in Case 1 and Case 2 on accessing the variable con.
thanx
Venki

>
If i am not wrong, the above line should be private
static variables are not inherited.
NO, AFAIK, static variables, private or otherwise arent inherited. Please note that doesnt mean, its not available in the sub-class. Infact it is. However you cannot override or hide them ie polymorphism isnt applicable to static members which is what , IMO, inheritance is all about. Its logical, when you think about it, polymorphism is applicable for objects and static is a class thinggy, has nothing to do with objects.

Difference Between Capture invoice and Only part1 in Migo

Hi All,
I am doing GRN posting in MIGO, its a excise material, in which i am selecting ONLY PART1 option in excise invoice tab.
After posting the document if i go and look into this GRN no in display mode it is not at showing this Excise Invoice tab.
Can any one tell how the scenario will work if i select --
1. ONLY PART1,
2. Capture Excise Invoice.
3. and other option like Capture excise invoice and post excise invoice.
4. No excise entry.
Also let me know is there any link between this and Accounting ie., J1IEX & MIRO....,
Please help me out in this.
Regards,
Nagaraj S

Dear Nagaraj,
RG23A register have 2 components, one is quantity part (part I)& other one is value part(part II). While doing GR you have the option of updating the Part 1 only, capturing excise invoice & posting excise inv.
Normally "only Part1" option will be used when the goods recd from vendor with no excise invoice enclosed (expected later)& you want to make Qty receipt. In this case you will update qty part in RG23A register & later capture & post excise invoice in J1ieX.
Second option is Capturing excise invoice in GR. In this case you will capture excise invoice at the time GR (here Part1 will get updated) & later post the excise invoice in J1iex t-code. This procedure will be used by most of the companies since qty part will be done by stores person & excise value part by excise officer separtely. This procedure will have a good control over the value part as it be double confirmed by the excise officer befor posting.
Third option where you can post the excise invoice directly at the GR level iteself & this process no need of J1iEX t-code.
However the selection of second & third option is controled by the CIN config setting.
For non excisable material select no excise entry.
Hope you understand.

Difference between capture rendering and video file rendering

Hello,
I am using JMF to process a video coming from a camera or from a video file, but I noticed some differences in the screen output between these two cases.
I created a Processor and attached an Effect plug-in to its codec chain. On every frame, some processing is done in the process() method of the Effect. Every automatic update of the processor's visual component fires automatic update of my transparent custom drawing pane positioned on top of it (because they overlap). This way I can easily draw some lines over the video layer.
This works fine on capture. When the video comes from a file, however, the JMF visual component always shows the previous frame (not the one just processed), so my drawings are out of sync (they are a step ahead from the frame displayed).
Why is that? The processing code is the same for the capture and the files, only the dataSource is created differently.
Thanks in advance!

Difference between database design and schema design

Hi i have visited so many database websites and i found so many people saying we can design a data base for you. Is schema designing and database designing is the same. so many palces i find people saying we have to design data base first in order to create a physical databse. so i am little bit confused. are they same? and also what is the difference between data model and schema?

> the definition i found for logical data model, physical data model and the definition you
gave for logical database design, physical database design are the same.
Not correct. The physical design is the implemetation of the logical design. These two designs are at different levels. Also, the logical design will be the same. irrespective of the RDBMS product use.
What is incorrect is a designer/architect designing a logical design specifically for Oracle.. or specifically for SQL-Server. A logical design has nothing to do with the RDBMS product (or h/w platforms. app servers, web severs and operating systems used).
So the logical design will always be the same - it is RDBMS independent.
The physical design is fully dependent on the RDBMS product used. The same logical design will be implemented as different physical designs for Oracle and for SQL-Server.

Difference between Database, instance and schema

Hi
I don't know the clear difference between database, instance and schema.. In the broad sense, everything seems to be the same. If anyone can differentiate between them with some example, that will be of great help.
Thank you.

Hi,
In Oracle, people often do use "database" and "instance" interchangeably, or together as one term: "database instance".
A "schema" is quite different. A schema is a collection of objects (such as tables, indexes or procedures). Every object belongs to exactly one schema, and every schema is a part of exactly one database. (Names may not be unique, however. For example, your database may have one schema named SCOTT, and another schema named USER1. Each of those schemas may have a table named EMP. The EMP table in the SCOTT schema, or SCOTT.EMP, is not the same as the EMP table in the USER1 schema, or USER1.EMP. A different database, my database for example, may also have schemas called SCOTT and USER1, which are completely independent of the SCOTT and USER1 in your database.)

Exporting and Importing of Schema

The Export and Import of Schema is not working consistently in SP4.
When I create a new repository from the schema, all the subtables get created. The main table is has only one field in it. It reads Category.
The other fields in the main table are missing and are not imported during the Import Schema operation.
Has anyone encountered the same issue?
If so, please let me know how you overcame this errorneous behaviour?

Hi Adhappan
I have tried importing without success. The import is not consistent. The same schema creates different sets of tables & fields each time. Sometimes if you reimport some more tables which were not set up the first time gets selected for import.
I did a simple exercise to test the import / export functionality.
1. I unarchived a repository from standard content provided by SAP
2. I exported the schema
3. I tried importing the schema without any modifications to schema
4. The results were highly inconsistent.

Important differences between oracle 10g and 11g

Hi friends, can anyone tell me (pointwise) what are the major (and minor) differences between Oracle 10g and 11g.
Please point me to some documents if possible.
Thanks in advance

The name of the link says it all: "top_features."
In short it is Oracle's list of what they have for marketing and sales reasons designated "top features."
It is not intended to be, and is not, a complete list of features. Often the features Oracle does not
talk about are the most important.
Let me give you some examples. I have never seen Oracle announce DBMS_XPLAN as a new feature
yet you should not run an explain plan without it. Neither have I ever seen Oracle announce the new
NO_DATA_NEEDED predefined exception. I have listed literally hundreds of new features you will not
find in Oracle's new features docs.
I did a presentation at OpenWorld this year as part of the unconference titled "New Features in
Database 11gR2 that Oracle will not announce." It was easy to prepare a one hour presentation with
little fear of being proved incorrect. As I turned out only one of the features I presented was mentioned
by Oracle.
You can find the presentation slides here:

Exporting and Importing the schema with AQ capability

Hi,
We have a production DB which is using Advance queuing and this whole queuing is working fine in Prod but now we have a problem in test Env and it seems that somebody has already tampered the test DB. (the queue reads and sends the messages to DB2)
So i wanted to export the prod schema and import it to the test schema that we have.
i wanted to make sure that if i import it to test db , it doesn't send the messages to the prod DB2 database!!
now it should send the messages to the test DB2 database.
How can i see where it sends the messages after i imported it ? how can i change it?
i'm not sure if i have explained my problem in a correct way and if you have understood my question. Please send me messages and i can explain more about it.

Sequences incorrect after exporting and importing a scheme

Hi all,
Can anyone tell me why when we export a scheme and import it again, all our sequences are not correct anymore? Everything else is exactly the same, just the sequences aren't correct anymore.
The last export was done in Oracle 10 and the import was done in Oracle 11. But we had this problem also when we were exporting on the same server.
If you need more information just ask.
Thanks,
Pieter

Lookout Datatable object can only read worksheet file, but unfortunately Excel 2007 can not save as worksheet any more.
I have not found a way to use datatable with excel 2007 yet.
One workaround is to use ODBC. Refer to this article.

Relational schema and difference berween relational schame and data base schema ?

Hi ,
Am new to Database
Can u help me to understand relational schema and data base schema ?
thanks

Hi Neil,
I'm not good with the relational schema, which is being deprecated. Given your results though, you might try
doing a count of distinct GIDs in the index table and compare it with the number of distinct geometries to make sure
your index is complete.
Also, if you have quadtree indexes at the same level in both Object-relational and relational then you can compare the
number of index entries in both models.
Hope this helps,
Dan

Importing voice - is there a difference between MPEG 1 and 2?

Hello,
I just bought a Digital Voice Recorder from Diasonic and want to upload a voice recording to Garage Band. It works on itunes and plays in the mediachooser in GarageBand, but cannot be placed as a new podcast track. When I look at the info, the only difference between my new voice recording and other podcasting I have downloaded from the Internet is that there is a difference between MPEG 1 and 2 (and my Diasonic uses MPEG 2). Can this be the problem? If so, what should I do?
Very grateful for a response.

Difference between extent management and segment space management

Hello,
Could you tell me the difference between extent management and segment space management interms of datablocks?

After 10g, default tablespace is locally managed and with this creation, your segment's spaces are managed "automatically".
Automatic segment space management is onlyt avaliable to locally managed tablespaces.
The logic of the automatic segment space management is;
For instance, we have a rectangle cube which is totally empty (1 extent - 8 segments - 64 block in default). If we enter a new data to our table, data is stored inside this cube with it's information. (default 8k). If our data must be splitted, check row chaining for further information.
At this point, oracle decides which block is filled with the entered data. It automatically fills the emty blocks. You can use this only if your tablespace is locally managed and your segment space managemet is auto.
On the other hand,
If we create dictionary managed tablespace,
Data is stored in "dictionary" (tables in SYS schema). This is a bit slower than locally managed tablespaces. So filling the extents, segments and blocks will be slow too. You need to specify the PCTUSED, FREELISTS, FREELISTS GROUPS for the storage of the data. If segment space managent is auto, you don't need to define those values.
In summary, locally managed tablespaces with automatic segment space management is Oracle's maybe the most important feature. I am not using dictionary managed tablespaces and i advice don't use it either. In the end, this is an upgrade of using segment spaces much more faster, easier and reliable, trustable.
PS: You will need to check "High Water Mark" for automatic segment space management.
