I have oracle 11gr2 database on linux os. It's total sga size is 500mb only. Now, if uses wants read the 1gb of data from database, then there is no sufficient memory in buffer cache. so how it will works. the transaction will get successful or it will fail.And i have another doubt, does oracle can read the data from memory only or it can also read directly from disk.

How much amount of data transfer over the network? How to calculate this value?
extract a huge amount of data from a couple of views... the problem is that they want it in TXT files with fixed record length. There will be like 6 files, for a total amount of about 10GB.
export those tables in the fastest possible way? If I'm not mistaken exp and expdp can't create txt files, so do I really need to use utl_file or spool?
I'm using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production and TNS for Linux: Version 11.2.0.3.0 - Production.Requirement is to create a script to add a LIST partition to some selected tables in a schema (tables do not have data, they are not partitioned). There are about 300 such tables (can vary) and their names are maintained in a separate table. Example -Existing table
-CREATE TABLE test_part(id number (2),
name varchar2(20),
audit_userid number (9));
Expected table
-CREATE TABLE test_part(id number (2), name varchar2(20), audit_userid number (9))
PARTITION BY LIST (audit_userid) (PARTITION p1_audit_userid VALUES (1));
Ultimate goal is to add more partitions based on the amount of data to be populated.
I am considering all of the capabilities and benefits of using Data Pump for exporting and importing extremely large data files. Would like to know if importing to tape is possible? If so, would the data be accessible if needed later?

Since XML-files only contain character data, we could/should store it in a CLOB, rather than a BLOB.
But, One of my friend having a table where a column is defined as bloband came to know that XML data are being stored. I searched for some article with keyword 'How to insert large XML data in BLOB' But did not work.How to store the large xml content in a Blob and How to extract it?
I have encountered some problems in SQL I want to create a table with a bunch of prepared data. For ease of use, I choose to generate a SQL file which contains all the sql clauses used to create the table and insert the data. So all the data can only be inserted to a table using sql clause.
My questions:
1) If data of a column is large (for example, 1 M text), how to insert it using SQL, is there a piecewise method.
2) And how can I insert BLOB data using SQL clause.
What I what is to enclose all the operations in a single SQL file, and when the table is needed, just execute this SQL file.
I am facing a problem with utl_http.write_text in my pl/sql application. My requirement is to write data of size>32k. So I used a clob variable in write_text. But still it is showing numeric or value error when the data size is above 8k.
I have read that chunked transfer encoding will work. But I couldn't find out how this is done.
what could be effective data type to store large integer values like, 50,000; 10,000,000 etc.?

I just need to see some sample data from a large table ( to see what kind of data which is application related ).
My question is :
Select *

where rownum < 10
is this a Good way to view the sample data ?
I have understanidng that the rownum will be assigined to the rows once all the rows are reteived.
So what is the best way to view ?..I am not sure of any condition to put in the intial time of querying.
Scenario:
Our application is using a two instance, one for the live active data and the other for the reports data. We have a process which moves the data from the live instance to reports instance every night. In a single db environment the process is working without any issues. However when we move to the RAC environment the reports db's (insert) in large table get locked and we are unable to insert data to the reports db.
What we are performing is:
Insert into my_table_rpt select * from may_table_live@db_link_to_livedb;
Issues:
my_table_rpt get locked
We have found the workaround by disable locking in destination and subsequent to the insert enable locking
ALTER TABLE my_table_rpt DISABLE TABLE LOCK;
Insert the data to the reports database table
Then
ALTER TABLE my_table_rpt ENABLE TABLE LOCK
Question:
Why does the large destination table (my_table_rpt) get locked in the RAC environment?
We have data archive scripts, these scripts move data for a date range to a different table. so the script has two parts first copy data from original table to archive table; and second delete copied rows from the original table. The first part is executing very fast but the deletion is taking too long i.e. around 2-3 hours. The customer analysed the delete query and are saying the script is not using index and is going into full table scan. but the predicate itself is the primary key,More info below

I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.

If all users can connect to Orcl db, I can count real user connections.

Getting total sales dollar amount from two tables.
T1
Item_no(number)Total_Sales_Number(number)
160
250
35
420
T2
Item_no(number)Sales_Date(date)Sales_Number(number)Sale_Price(number)

22012-01-104016
22012-03-053018
32012-02-011020
Required to generate report to total sale dollar amount by combining information from T1 and T2 (matching with item_no). Rules are
a)Formula is Sales_Number*Sale_price
b)Choose the earliest sale record to latest by Sales_Date with the sum of Sales_Number is less or equal the Total_Sales_Number from T1.
c)If the sum of Sales_Number is less than the Total_Sales_Number from T1, then the use a fixed price for all items, say $10
d)If a item is not in T2 then use $10 for the price
For example,
item_no 1:
Total sale dollar amount = 20*$15+30*$15+(60-20-30)*$10
item_no 2:
Total sale dollar amount = 40*$16+(50-40)*$18
item_no 3:
Total sale dollar amount = 5*$20
item_no 4:
Total sale dollar amount = 20*$10

I'm working on a project and I can't figure out the procedure I will need to use. I've got a sysdate field in my "Calls" table which generates a call date + time, however I need to insert a severity level of the call after a certain amount of time, e.g. after 1 hour level turns from level 4 to level 3 and so forth until reaching level 1 after x amount of time. I know I'd need to put in an else if statement within this procedure I just can't work out how to do it with the sysdate field that has also been created.
A bit of info about the table, table name = calls, column 1 = date_time and column 2 is called severity_level

I can calculate the average sick days etc, but It wont see to allow me to find the difference between that and the amount of sick days that each person has had. I have tried this many ways and have not been able to come up with a solution.
