I have table a in database 1 . Now i have created the MV for table a in database 2.
then i am going to create a synonym in different schema in the database 2.
Now i want to update the synonym in database 2 the same as to refresh in table a database 1.
How to achieve this??
difference between the ways we create Reverse Key Index on the table.The two ways are as below:
1) CREATE INDEX <Index_Name> ON <Table_Name>(<Column_Name) REVERSE ;
2) CREATE INDEX <Index_Name> ON<Table_Name>(REVERSE(<Column_Name>)) ;
Which one is the appropraite one.
Are both going to act in the same way.
I created index in both ways one by one on the table.But when I fire the select statement against the same table, The explain plan doesn't show any cost and it shows the full table scan in both ways.The select statement used is as below...I want to compare the column with string RBO(i.e('RBO%') at the start.
SELECT *
FROM <Table_Name>
WHERE REVERSE (<Column_Name>) LIKE '%OBR' ;
The select statement is giving me the correct result. Only the explain plan is showing Full Table Scan.can we use this reverse with IN operator also in the same way by reversing the values.

I am trying to update of job_id column of employees table for employee number 205 two times one after another. First time job_id column of employees table for employee number 205 is updated with new job_id. But second time job_id column of employees for employee number 205 table can not be updated. Oracle returns the following errors
HR:orcl > update employees set JOB_ID='AC_MGR' where employee_id=205;
update employees set JOB_ID='AC_MGR' where employee_id=205
*
ERROR at line 1:
ORA-00001: unique constraint (HR.JHIST_EMP_ID_ST_DATE_PK) violated

ORA-06512: at "HR.UPDATE_JOB_HISTORY", line 2
ORA-04088: error during execution of trigger 'HR.UPDATE_JOB_HISTORY'
As there is composite primary key using employee_id and start_date column.how to update same employee job_id twice.AS we can see from job_history table, the record for employee 200 is as follow
EMPLOYEE_ID START_DATE END_DATE JOB_ID DEPARTMENT_ID
----------- ----------- ---------- ---------- -------------
200 17-SEP-1987 17-JUN-1993 AD_ASST 90
200 01-JUL-1994 31-DEC-1998 AC_ACCOUNT 90
So how can i do the same for employee 205 without changing hire_date after first job_id update. Since for every update of job_id fires trigger. To insert row in job_history table employee id and start_date must be unique each time. HERE hire_date of employees table is used as start_date of job_id table. how it was possible for employee id 200 to change job_id twice?
I've read some documentation about the reverse key indexes, but I haven't understood when really it can be useful use them. when it's smart to use them according to your experiences?

I know that this application is a problem but we have to install
I can do this by creating trigger on each table will restrict DML. As example: if the operating system user is XXX, the trigger restrict the action. But not logic at all to create more than 1000 triggers on schema (This will impact badly on DB performance).
So, i need to create one trigger to fire before doing any DML on all schema tables. As example: If "MMM" the administrator operating system user trying to do insert action, he can do the action. BUT If "DEV" the developer operating system user trying to do insert action, the trigger must fire here to restrict this action.
Be noted also, i need this trigger not depend on any specific tool like Toad as any user can simply rename the exe file for toad then he can pass the trigger. At least, trigger must depend on (Operating system user & Action_type)

On the database instance where you want to install Coeus, create a user who will be the owner of Coeus schema. This user should have at least the following privileges. CREATE TABLE, CREATE VIEW, CREATE PROCEDURE, CREATE PUBLIC SYNONYM, CREATE USER, CREATE ROLE, CREATE SEQUENCE, CREATE SESSION CREATE TRIGGER, AND CREATE TYPE. If you choose, you can grant DBA role to this user.
Note: Coeus Schema owner should have CREATE USER and ALTER USER right explicitly granted to it, not through a role like DBA.

This is a bit wierd. I am surprized that Oracle guys haven't done anything about this . This is like DB2 !
I would like to create a trigger that will fire whenever any user will access to a Schema of Oracle DB (for each and every login). regardless the access will be through an application or SQLPLUS and this trigger must insert the below information into a table.
1) IP address
2) Machine Name
3) login time
4) logout time
5) name of accessed schema
writing this trigger and creating the table that will hold the required data.
I want to create a block of code that would search in all tables in a schema for a column_name where its data_length is like 4000 let's say. This data_length is actually dedicated for a comment column. If found, all not null column with like 4000 data_length will be changed by string "Comment has been removed". I have the following script below but it seemed lacking.
begin
for rec in (select table_name, column_name from user_tab_columns where column_name like ?data_length? = 4000 order by 1,2) loop
begin
execute immediate 'update '||rec.table_name||' set '||rec.column_name||' = ''Comment has been removed'' where '||rec.column_name||' is not null';

Oracle Version: 11gR2: 11.2.0.1.0 - 64bit
OS: Linux Fedora Core 17 X86_64
Currently, I'm reading the online book Oracle Concepts, Chapter 3: 3 Indexes and Index-Organized Tables, section: Reverse Key Indexes in order to understand this topic.
As I understand for each pair of (key, rowid) in the index structure, the rowid for each row in the table obviously remains the same but the bytes of the key are reversed before the key is stored. So for example on a 32 bit machine (just an example) a key = 10 AB CD EF will be stored as FE DC BA 01 , am I right?
According to the documentation, this becomes interesting in RAC environments in order to remove a hot spot from the index (when multiple instances repeatedly modify the same block) with the disadvantage that in some cases there cannot be Index Range Scan any more as data in the index is not sorted by column key when it is stored.
I was just curious to see how bytes of each key are reversed and after a bit googling I found an article where Tom Kyte shows with an example by using dump function (which as I understand gives the internal representation of a given expression) the difference in the sequence of bytes. Here is the link
[URL]
So based on his instructions I tried to do my own test, yet I don't get the same result, that is, the bytes are not reversed for me once we rebuild the index by REVERSE key word.
I'm going to write down here the test that I did, where is/are my error(s)
Test Case:
(I use a copy of the employees table in hr sample schema)
SQL> CREATE TABLE emp_test AS SELECT * FROM hr.employees;
Table created.
SQL> CREATE INDEX emp_test_idx ON emp_test(first_name);
[code]...
Now, a test SQL Query using the index we've just defined (just for giving an example)
SQL> SELECT first_name,
2 dump(first_name, 16) as dump_result
3 FROM emp_test
4 WHERE first_name = 'Kelly';
FIRST_NAME DUMP_RESULT
-------------- ----------------------------------
Kelly Typ=1 Len=5: 4b,65,6c,6c,79
[code]...
So, according to the above Execution plan, Oracle does an Index Range Scan using the index that I defined on my table that is, emp_test_idx. According to the output of dump, the key (first_name) in that index is stored (in terms of bytes) as 4b,65,6c,6c,79
SQL> SELECT chr(to_number('4b', 'xx')) ||
2 chr(to_number('65', 'xx')) ||
3 chr(to_number('6c', 'xx')) ||
4 chr(to_number('6c', 'xx')) ||
5 chr(to_number('79', 'xx')) first_name
6 FROM DUAL;
FIRST_NAME
--------------------
Kelly
Which as we can see corresponds to the first name 'Kelly', the first name we specified in the above SQL query.
Now let's rebuild the index
SQL> ALTER INDEX emp_test_idx REBUILD REVERSE;
Index altered.
SQL>
Once the index keys have been reversed, I run the very same query in order to see the difference
SQL> SELECT first_name,
2 dump(first_name, 16) as dump_result
3 FROM emp_test
4 WHERE first_name = 'Kelly';
[code]...
So the second time after the index has been reversed, I still get the very same sequence of bytes, that is, 4b,65,6c,6c,79, whereas I expected to get 79,6c,6c,65,4b (that is, the reversed order of the initial bytes sequence)
I want to import a schema from one database schema to another schema b from db STBTST to STATST and from schema CMSSTAGINGB to CMSSTAGINGA

So i've created a dump from STBTST-CMSTAGINGB For importing im using this statement:
impdp mvanmannekes/password schemas=cmsstagingb remap_tablespace=cmsliveb_data:cmslivea_data
