Table data size in oracle 11g

Hi All,
how to find the data size in particular Table?
Ex:I need find out the sh.sales table how much data size is loaded
Thanks,

USER_SEGMENTS (or DBA_SEGMENTS)
And if it's a partitioned table, don't forget to sum the sizes.
You may also want to include any indexes on the table.

Writing a stored procedure to import SQL Server table data into a Oracle table

Hello,
As a new DBA I have been tasked with writing a stored procedure to import SQL Server table data into an Oracle table. I have been given many suggestions on how to do it from SQL Server but I I just need to write a stored procedure to run it from the Oracle side. Suggestions/guidance on where to start would be greatly appreciated! Thank you!
I started to write it based on what I have but I know this is not correct :/
# Here is the select statement for the data source in SQL Server...
SELECT COMPANY
,CUSTOMER
,TRANS_TYPE
,INVOICE
,TRANS_DATE
,STATUS
,TRAN_AMT
,CREDIT_AMT
,APPLD_AMT
,ADJ_AMT
,TRANS_USER1
,PROCESS_LEVEL
,DESCRIPTION
,DUE_DATE
,OUR_DATE
,OUR_TIME
,PROCESS_FLAG
,ERROR_DESCRIPTION
FROM data_source_table_name
#It loads data into the table in Oracle....
Insert into oracle_destination_table_name (
COMPANY,
CUSTOMER,
TRANS_TYPE,
INVOICE,
TRANS_DATE,
STATUS,
TRANS_AMT,
CREDIT_AMT,
APPLD_AMT,
ADJ_AMT,
TRANS_USER1,
PROCESS_LEVEL,
DESCRIPTION,
DUE_DATE,
OUR_DATE,
OUR_TIME,
PROCESS_FLAG,
ERROR_DESCRIPTION)
END;

CREATE TABLE statements would have been better as MS-SQL and Oracle don't have the same data types.
OUR_DATE, OUR_TIME will (most likely) be ONE column in Oracle.
DATABASE LINK
Personally, I'd just load the data over a database link:
insert into oracle_destination_table_name ( <column list> )
select ... <transform data here>
from data_source_table@mssql_db_link
As far as creating the database link from Oracle to MS-SQL ... that is for somebody else to answer.
(most likely you'll need to use an ODBC driver)
EXTERNAL TABLE
If the data from MS-SQL is in a CSV file, just use and external table.
same concept:
insert into oracle_destination_table_name ( <column list> )
select ... <transform data here>
from data_source_external_table

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

Optimal NTFS block size for Oracle 11G on Windows 2008 R2 (OLTP)

Hi All,
We are currently setting up an Oracle 11G instance on a Windows 2008 R2 server and were looking to see if there was an optimal NTFS block size. I've read the following: http://docs.oracle.com/cd/E11882_01/win.112/e10845/specs.htm
But it only mentioned the block sizes that can be used (2k - 16k). And basically what i got out of it, was the different block szes affect the max # of database files possible for each database.
Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?
Thanks in advance

Is there an optimal NTFS block size for Oracle 11G OLTP system on Windows?ideally FS block size should be equal to Oracle tablespace block size.
or at least be N times less than Oracle block size.
For example - if Oracle BS=8K then NTFS BS better to be 8K but also can be 4K or 2K.
Also both must be 1 to N times of Disk sector size. Older disks had sectors 512 bytes.
Contemporary HDDs have internal sector size 4K. Usually.

Hi there
you have date data type in Date_Of_Birth you have to use to_date function
try this
select case((Date_Of_Birth)when to_date('01/01/1900', 'DD/MM/YYYY')
then ''
ELSE TO_CHAR(Patient.Date_Of_Birth, 'DD/MM/YYYY')
END Date_Of_Birth

How to generate TPC-E schema/data sets in Oracle 11g

Hi,
I want to use TPC-E schema in my Oracle 11g database (Standard) and also want to use DATA SETS from this benchmark for some kind of testing.
I've download EGen v1.8.0 from this TPC website:
http://www.tpc.org/tpce/default.asp
but don't know who to implement this benchmark database into my computer's database. I'll appreciate if someone please suggest me how to do this...
Thanks alot.

I want to find Optimal size of a data block size as this is the one parameter which can increase the performance of a database or decrease it.If there is a single optimal size, that would surely be the default Oracle block size - as Oracle should know perhaps better than any of us, just what block size differences do as it is their code that uses it?
Can I ask why you said that you would not have chosen this topic as a thesis?My leaning has always been to expert systems and A.I. Even designed and written my own expert system language years ago. One thing that is critical in such systems is how you structure data - and that has a nice database angle to it. One that I believe can still be exploited for research purposes.
Don't you think that it'll benefit DBA's or database developer after I reach a successful conclusion?To be honest, in the real world of database systems, the least of my concerns are data block sizes. For example, we're busy putting together a storage array that should have a maximum I/O pipe size of 40Gb. In comparison, we currently use dual 2Gb fibre channels on most of our servers for our I/O.
Technology moves fast. And perhaps there is an ideal block size for the standard storage array and Oracle instance today - but that could invalidated by new technology next year. Would I want to spend time and effort studying and analysing and researching a very specific technical subject, that perhaps is not considered as of that critical importance by DBAs and perhaps can be outdated with new technology and techniques?
I honestly do not want to put you off studying db block sizes. Perhaps there's still some critical issues to uncover in that respect. But personally.. there are many other subject areas in database technology that peak my interest a lot more. But then you have your personal preferences and likes and dislikes - and data blocks could be your muse. :-)

Anyone inserted data directly from Oracle 11g to MySQL?

Hi There,
We work mainly on Oracle 11g. However, there is a requirement to now connect to an external MySQL database from our company's Oracle Database. Would be trying to do this for the first time. The process would be to download the data using PL/SQL from the ORacle 11g DB and then insert the data into the MySQL DB table. Had a few questions,
1. Are there any known issues with connections between ORacle as source and MySQL as target. Anything that needs to be kept in mind?
2. How do we send the data to MySQL, I mean in PL/SQL we can have the procedure create the insert statements. But can we directly fire the insert on MySQL ? If yes, any suggestions on what the commands would be?
3.Any way to figure out if the insert was successful?
4. We might also have to do other operations like update/delete etc.
5. Any possible reference or sample code on this would also help.
Thanks

Well, the simplest and most direct approach would be to create a java function in the database to perform the operation and call it from pl/sql. I've done it before and there are examples out there and its a pretty straight-forward process.
A quick example from [this website|http://w2.syronex.com/jmr/edu/db/oracle-and-java]
import java.io.*;
import java.sql.*;
public class OraThin {
public static void main(String[] args) {
    try {
      Connection con=null;
      Class.forName("oracle.jdbc.driver.OracleDriver");
      con=DriverManager.getConnection(
        "jdbc:oracle:thin:@machine_name:1521:database_name",
        "scott",
        "tiger");
      Statement s=con.createStatement();
      s.execute("
        INSERT INTO BOOKS VALUES
        'A Tale of Two Cities',
        'William Shakespeare',
        4567891231,
        '5-JAN-1962'
      s.close();
      con.close();
   } catch(Exception e){e.printStackTrace();}
}Check out Oracle's Java tutorial at http://docs.oracle.com/javase/tutorial/jdbc/basics/storedprocedures.html for more in-depth information.
If you're going to be doing this for more than a handful of tables under very controlled circumstances keeping it synchronized is going to be a mess, however.

Failed to get Column's data type in Oracle 11g

Hi,
I made an ADO connection(Oracle provider) to Oracle 11g, and use ADO API: OpenSchema(adSchemaColumns) to fetch the columns' info. But I found I couldn't get the column's data type if it's type is timestamp or timestampwithtimezone in database. What I got is 'adIUnknown' whose number is 13.
I test with another column whose data type is 'date', and everything is ok. I get the data type 'adDBTimeStamp'.
This issue occurs on Oracle 10g, too.
Can anyone offer some help? Thanks a lot!

How to change archivelog file size in oracle 11g

Hello,
In my oracle 11g database inside flash recovery area how to increase each files size , now it 41 Mb per file iits name is o1_mf_1_161_8mfpwtbj_.arc how to change it to
the understandable name.
Thanks and regards

Hi,
As you know archived log is create when online log is switch. Archived log size might be maximum equal to online redo log size.
Because archived log size is copied from online redo log file, if you want change archived redo log size, then you must change online redo log size.
But you must think, what is advantages and disadvantages of change of online redo log size, it depends direct task LGWR process.
You can change archived redo log name with change LOG_ARCHIVE_FORMAT parameter.

Enforce date datatype in oracle 11g

Can I restrict database so that application can not enter date data in certain format.
E.g. If I want that date enter should be registered in [year to minute] 'MM-DD-YYYY' hh:mm' only format and not in [year to second format]'MM-DD-YYYY' hh:mm:ss' then how I can do it in Oracle 11g.
Currently I am using oracle sql developer to create data model and then I want to generate DDL from that to generate database. Is there is any facility in Oracle SQL developer to enforce format specification.
thanks!

This is not really related to SQLDeveloper, so you may find better answers in another forum but I'll try to give you an idea anyway.
Actually the DATE datatype has no format, you use a format when you convert it to a string or vice versa, but the DATE itself is just a DATE.
You could probably create a trigger to truncate your data as you see fit, but IMHO your best option would be to remove the seconds from your output queries using something like
TO_CHAR(YOUR_DATE_FIELD,'MM-DD-YYYY HH24:MI')you can also set this output format for SQLDeveloper in
Tools -> Preferences -> Database -> NLSbut this will work only for SQLDeveloper, it's up to you to determine the best way of setting the output/input date format in your specific application.

How to migrate 'table' data type into oracle solution?

Say, I have following sample code in Sql Server:
Declare @v1 table(old_value int, new_value int)
insert into @v1 select old_value, new_value from aTable where....
declare cur cursor for
select new_value from @v1 where old_value=...
what should I use in oracle to convert above code? I was thinking about nested table, but it seems not very suitable here. Any better solutions out there?

It's been a while since I've done any SQL Server development, but if I recall correctly, a table data type in Transact SQL is used for storing temporary result sets.
In your example, you seem to be temporaily storing the results of a query in a Transact SQL table, and then opening a cursor to iterate over the results.
In Oracle PL/SQL, there is usually no need to do this, just open a cursor:
create or replace procedure test_proc as
begin
for curs_rec in (select old_value, new_value from myTable) loop
... process each row ...
end loop;
end test_proc;
If you really want your results in an array which your code can iterate over, look into the BULK COLLECT clause of the SELECT statement:
create or replace procedure test_proc as
TYPE array_type IS TABLE of myTable%ROWTYPE INDEX BY BINARY_INTEGER;
my_array array_type;
begin
SELECT * BULK COLLECT INTO my_array FROM myTable;
for idx in my_array.FIRST..my_array.LAST loop
dbms_output.put_line(my_array(idx).col1);
end loop;
end test_proc;
Note that I have not actually compiled the above code, so there may be syntax errors :)
Also, prior to 9i you can not BULK COLLECT into a table based on a rowtype (you need to created an array for each attribute).
SQL Server also allows function which return table types. This is similar to PL/SQL pipelined table functions (available in 9i and higher - see the PL/SQL guide), which can be used to materialize rows which can be processed like any other result set.
SQL Server also has a concept of temporary tables which is totally different than Oracle's temporary tables. SQL Server developers must often resort to using temporary tables in their stored procedures; in Oracle, this is rarely necessary.

Table move after data deletion in oracle 11g

Hi,
Our previous system was in oracle 9i, And we used to archive our data in every 1 year which caused a huged number of DML operation our database. After that,we used to move our table and rebuild indexes to releases spaces. After Upgradation ,our presence system is running on oracle version 11.2.0.2. Now my question do we need to move table in 11g to release space?? Or it automatically done in 11.2.0.2???
Thanks and Regards,

Now my question do we need to move table in 11g to release space?? Or it automatically done in 11.2.0.2???If you move that space will be released from those extents but you wont gain any space at OS level until unless you shrink datafile. Move command will do the job.
did you see what is the free space in tablespace after moving objects?
