DDL or DML changes in RAC

Hi,
I have a question about DDL or DML changes in RAC? Assume we have 2 node RAC and If I issue an update stmt in one instance and issues same update stmt in another instance, which will take effect?

Hi,
It means first commit won't take effect?It will, but only until you issue the second update/commit. RAC is more than instance accessing the same database (same tables).

DDL and DML separators in sql file

Hi,
I have sql files with database changes in them. DDL:s and DML:s mixed. Unfortunately I cannot run them without doing some 'cleaning up' witch is very time consuming.
I would like to write a VB (or similar) program that replaces the ';' with '/' at the end of a statement and puts in '/' after packages e.t.c so I can run the file in one go.
The problem is to know where a trigger, package, insert, modify and what not, ENDS. What code belongs to object x and y so I know where to put in the '/'.
Is there a way to find out what is a DDL or DML and where they start and ends?
Cheers,
Magnus

You can remove GO or batch separator if you don't have:
1. same variables declared in more than 1 batch
2. CREATE/ALTER VIEW/PROCEDURE statements, they should be first statement in the batch otherwise will fail. (otherwise it will give you following error: CREATE/ALTER VIEW/PROCEDURE' must be the first statement in a query batch.)
3. there could be more things, just check based upon my above 2 points.

SQL Server 2000 auditing on DML changes on user tables to user databases

Please let me know if you know if there is any procedure or steps to determine DML changes on user tables in database.

Hello,
You can use triggers as shown in the following article:
http://sqlserver2000.databases.aspfaq.com/how-do-i-audit-changes-to-sql-server-data.html
You may also consider third party tools that may still support SQL Server 2000. The following tool supported SQL Server 2000 a few years
ago, not sure about today:
http://www.apexsql.com/sql_tools_comply.aspx
Server side traces may be another option:

Pipelined function ignores DML changes on subqueries

Hello all,
I have a really specific issue when using a pipelined function used in a complex subquery where the function ignores the changes made on the current transaction. The problem is the hidden hint materialize sometimes used by the Oracle optimizer. I say sometimes because it depends mostly on the execution plan and the complexity of the query.
I can repeat the problem with a dummy scenario.
Let's say we have a dummy table with a simple record :
CREATE TABLE DUMMY ("NAME" VARCHAR2(50 BYTE));
INSERT INTO DUMMY VALUES('Original name');
We then create a package which will contain our pipelined function and its record object and collection:
CREATE OR REPLACE PACKAGE PKG_DUMMY AS
TYPE DUMMY_RECORD IS RECORD (NAME VARCHAR2(50 BYTE));
TYPE DUMMY_RECORDS IS TABLE OF DUMMY_RECORD;
FUNCTION FUNC_GET_DUMMY_NAME RETURN DUMMY_RECORDS PIPELINED;
END PKG_DUMMY;
CREATE OR REPLACE
PACKAGE BODY PKG_DUMMY AS
FUNCTION FUNC_GET_DUMMY_NAME RETURN DUMMY_RECORDS PIPELINED AS
BEGIN
FOR CUR IN ( SELECT * FROM DUMMY )
LOOP
PIPE ROW (CUR);
END LOOP;
END FUNC_GET_DUMMY_NAME;
END PKG_DUMMY;
With this SQL query, we can return the value of the table by the pipelined function :
WITH DUMMY_NAME AS
SELECT "NAME"
FROM TABLE(PKG_DUMMY.FUNC_GET_DUMMY_NAME())
SELECT "NAME"
FROM DUMMY_NAME
Result
Original name
If we modify the DUMMY table with a new name without a commit, and re-execute the query, we got the same result :
UPDATE DUMMY SET "NAME" = 'New name';
Result
New name
But if we add the materialize hint in the subquery (without doing a commit or rollback), we have the original value hence my issue :
WITH DUMMY_NAME AS
SELECT /*+ materialize */ "NAME"
FROM TABLE(PKG_DUMMY.FUNC_GET_DUMMY_NAME())
SELECT "NAME"
FROM DUMMY_NAME
Result
Original name
I know I can force my subquery to use an inline hint instead of the "materialize" hint chose by the optimizer but then the query lose a lot of performance. Is there a way to force Oracle to use current DML changes with the materialize hint on a pipelined funtion in a subquery?
This thread is also for this issue : http://stackoverflow.com/questions/1597467/is-using-a-select-inside-a-pipelined-pl-sql-table-function-allowed

16 rows selected.I can point out that the TABLE ACCESS FULL of the global temporary SYS_TEMP_0FD9D780C_BD7649E3 table created by Oracle in response to the -materialize hint is returning *0 rows* in operation 5.
Why?
It seems for me that the reason for that comes from the fact that the creation of this SYS_TEMP_0FD9D780C_BD7649E3 table is done via direct path read/direct path write and as far as
the insert of *'Original name'* has not been pushed yet into the disc then materializing the query will generate an empty temporary table (empty in this case).
This is why if I had committed I will not have seen such a kind of discrepancy between those two queries
What do you think?

How to Split ddl or dml statement

Hi guys,
i'm using oracle 11.2
i've the following question.
i've a string that can contains multiple ddl or dml statement and i need to split them in more statement.
i.e. i can have a string like the below and i need 2 string each one with a statement:
insert into TEST_KIT_USER1.table1 values (1,'a');
insert into TEST_KIT_USER1.table1 values (2,'b');
otherwise i can have a string like the below and i need 2 string each one with a statement:
create table TEST_KIT_USER1.table2
name char(10),
surname CHAR(10 BYTE)
create table TEST_KIT_USER1.table3
id number,
description CHAR(10 BYTE)
is there a simple way to do this?

Have you tried using iMovie?
I know that iMovie HD '06 can do this, I'm not sure if '08 can.
If you have iLife '08, you can download iMovie HD '06 from apple's site here.
Good luck!

How to Track DDL and DML Operations happening in Backend into Log Files....

Hi I have one requirement for Tracking the DDL And DML Operation happening in Backend once the user Inserts or Updates any Table.How to Implement the same can anyone proviode the code for the same.
Ex: I have multiple tables in my database if any user fires the DDL or DML it should make entry in the Log file as
Name of the Table Operation Timestamp
X Insert DD-MM-YYYY HH24:MM:SS
Y Update DD-MM-YYYY HH24:MM:SS
Z Delete DD-MM-YYYY HH24:MM:SS
L Select DD-MM-YYYY HH24:MM:SS
Is it Possible to Develop it through Procedure,Function or Package,please give me Idea,,,,,

Please do not post same question in multiple forum. How to Track DDL and DML Operations happening in Backend into Log Files....
What's wrong with the answers posted in the above forum ? Do you go through the "AUDIT" option as suggested in the above post by various members ?

Auditing DDL and DML statements of selective IP addresses....

Hi all,
DB : 11.2.0.2 64 bit
OS : RHEL 5.7 64bit
Hi all,
I want to audit all DDL and DML statements for some selective IP Addresses or hostnames.
I read about Fine Grained Audit. I got the following code to enable auditing of nondatabase user's actions(Application users).
created policy for client identifier.......
BEGIN
DBMS_FGA.ADD_POLICY(OBJECT_SCHEMA => 'OE',
OBJECT_NAME => 'ORDERS',
POLICY_NAME => 'ORDERS_FGA_POL',
AUDIT_CONDITION => 'SYS_CONTEXT(''USERENV'', ''CLIENT_IDENTIFIER'') = ''Robert''',
HANDLER_SCHEMA => NULL,
HANDLER_MODULE => NULL,
ENABLE => True,
STATEMENT_TYPES => 'INSERT,UPDATE,DELETE,SELECT',
AUDIT_TRAIL => DBMS_FGA.DB + DBMS_FGA.EXTENDED,
AUDIT_COLUMN_OPTS => DBMS_FGA.ANY_COLUMNS);
END;
But I want to audit all DDL and DML statements for a particular schema say ABC from selective IP addresses or hostnames so how can I do this?
Pl suggest.....
Regards,
Andy.

Hi,
You could :
1. create a function, say myfunction, returning 1 if you want to audit, 0 otherwise
This function would test sys_context('userenv','ip_address') within the desired IP address to be audited
2. create your fga on the objects you want to audit adding the clause audit_condition=>'myfunction=1'

HR Schema DDL and DML Statements

Dear all,
I want all tables and datas for practicing purpose.(HR Schema)
In Oracle site where can I get these DDL and DML Statements.
Can Any one post all statements..
Thanks in advance.

Unlocking the Sample Tables
The Human Resources (HR) Sample Schema is installed as part of the default Oracle Database installation. The HR account is locked by default.
You need to unlock the HR account before you can use the HR sample schema. To unlock the HR account, log in as the SYSTEM user and enter the following command, where your_password is the password you want to define for the user HR:
ALTER USER HR IDENTIFIED BY your_password ACCOUNT UNLOCK;
For further information about unlocking the HR account, see the Oracle Database Sample Schemas guide. The HR user is primarily to enable you to access the HR sample schema and is necessary to enable you to run the examples in this guide.
Each table in the database is "owned" by a particular user. You may wish to have your own copies of the sample tables to use as you try the examples in this guide. To get your own copies of the HR tables, see your DBA or see the Oracle Database Sample Schemas guide, or you can create the HR tables with the script HR_MAIN.SQL which is located in the following directory on UNIX:
$ORACLE_HOME/DEMO/SCHEMA/HUMAN_RESOURCES/HR_MAIN.SQL
And on the following directory on Windows:
%ORACLE_HOME%\DEMO\SCHEMA\HUMAN_RESOURCES\HR_MAIN.SQL
To create the HR tables from command-line SQL*Plus, do the following:
1.
Ask your DBA for your Oracle Database account username and password.
2.
Login to SQL*Plus.
3.
On UNIX, enter the following command at the SQL*Plus prompt:
SQL> @?/DEMO/SCHEMA/HUMAN_RESOURCES/HR_MAIN.SQL
On Windows, enter the following command at the SQL*Plus prompt:
SQL> @?\DEMO\SCHEMA\HUMAN_RESOURCES\HR_MAIN.SQL
To remove the sample tables, perform the same steps but substitute HR_DROP.SQL for HR_MAIN.SQL.

DDL and DML tool for unicode

Which tool is able to maninupalate UTF-8 encoded data saved in Oracle database?
(execute DDL and DML commands with non latin text)

Hi,
You can easily create your own scripts for creation (and even deletion/drop) of tables and inserts made to those tables. You just need to put the statements in a notepad and save it with a .sql extension. Then run this file from a SQL prompt with @ sign. For example
SQL >@"c:myscript.sql" .
Hope this helps

Trigger for logging changes(DML changes) for All tables in Schema

Hi ,
Is there a way to create a schema level trigger to audit the DML changes that affect all the tables.I need the output in my log table as
1) the table name on which the DML occurred
2) type of DML
3) column names affected.
I know this can be achieved through enabling AUDIT or by creating dynamically, triggers for each tables...
Is there a way to create a single trigger to achieve this??

It's not possible to create DML trigger on schema level
I think the only way is to create the triggers dynamically for each table..

So much debate what is SELECT DDL or DML ??

Hello,
I am very much confused. So many resources available on the net about the SELECT statement. Most of them say it is a DML.
But my Consultant said that it is a simle query language neither DDL nor DML.
And I am very much convinced with this.
Can anyone please suggest.

SQL defines two sorts of statements: Data Definition Language and Data Manipulation Language. We use DDL to specify the objects to hold our data. We use DML to manage the data. In this context manipulation includes displaying our data. If you don't believe me trying read the Oracle Concepts doc. Quote:
Data Manipulation Language (DML) Statements
These statements manipulate data. For example, querying, inserting, updating, and deleting rows of a table are all DML operations. The most common SQL statement is the SELECT statement, which retrieves data from the database. Locking a table or view and examining the execution plan of an SQL statement are also DML operations.
Your consultant loses 10 culture points.

How do I setup RMAN not to delete archive log files on the source database so GoldenGate can process DDL/DML changes?

I want to setup RMAN not to delete any archive log files that will be used by GoldenGate.   Once GoldenGate is completed with the archive log file, the archive log file can be backup and deleted by RMAN.   It's my understanding that I can issue the following command "REGISTER EXTRACT <ext_name>, LOGRETENTION" to enable to functionally.   Is this the only thing I need to do to execute to enable this functionally?

Hello,
Yes this is the rigth way using clasic capture.
Using the command : REGISTER EXTRACT Extract_name LOGRETENTION.
Create a Oracle Streams Group Capture (Artificial) that prevent RMAN archive deletion if these are pending to process for Golden Gate capture process.
You can see this integration doing a SELECT * FROM DBA_CAPTURE; after execute the register command.
Then, when RMAN try to delete a archive file pending to process for GG this warning appear AT RMAN logs:
Error:     RMAN 8317 (RMAN-08317 RMAN-8317)
Text:     WARNING: archived log not deleted, needed for standby or upstream capture process.
Then , this is a good manageability feature. I think is a 11.1 GG new feature.
Tip. To avoid RMAN backup multiples times a archive pending to process, there is a option called BACKUP archivelog not backed 1 times.
If you remove a Capture process that is registered with the database you need to use this comand to remove the streams capture group:
unREGISTER EXTRACT extract_name LOGRETENTION;
Then if you query dba_capture, the artificial Streams group is deleted.
I hope help.

IP based restriction on DDL and DML statement

Hi
I am working oracle 10g daabase.I want to restrict a specific IP for all DML and DDL and the that particular IP should have only select only rights.Kindly let me know if its possible?
Regards
Vijay

Dear friends,
To be more clear on my requirement,i will explain you entire scenerio.
Example
There is person called John,and in a database BANK,there is are
3 schemas called
1) ABC (This schema has full privileges on its own schemas)
2) DEF (This schema has full privileges on its own schemas)
3) XEF (This schema has full privileges on its own schemas)
The priveleges of ABC,DEF and XEF cannot be reduced as they are related to application functiaonality,and any
change in the same will affect the application modules.Neither can we change the passwords for the above schemas,because this needs a bigger activity by incorporating the new password in all applications files.
Mr John has login creditanals for all there schemas i.e ABC,DEF and XEF.And thus he has full privileges on this schemas.
So we want John's IP with restriction of only select on this schemas.
In this example Mr john is the application vendor,and we would give him access to single IP for just one day.
Regards
Vijay

Application changes for RAC

We are having 8 different applications supported by a single instance database with 8 different schema for each of these applications. We are planning to move these schema to a oracle RAC environment for high-availability reasons. While I am very conformable with setting up the RAC environment( 2 node) , I have questions about how well the applications can function as soon as I migrate all
the schema to the 2 node RAC. My questions are :
a >> Do I need to have the developer change anything in the application code in order to support the RAC.
b >> How can I ensure the load balancing of the application happen after migration
c >> Is there anything I have to do to make sure the application really works well in this environment so as to make the investment in time /money/effort is worthwhile ?
Appreciate your response

You may want to look at any sequences. By default, they will have been created with NOORDER which can cause unexpected results in a clustered database.
And for your other question, are you sure you want load balancing? You said that the purpose of the RAC was high availability, so i would think that you need to look at service and session failover, not load balancing.

SQL Server 2000 auditing/tracking DML changes on specific tables.

Hello,
We would like to audit/track all DML activities on couple of tables which reside on SQL Server 2000. Triggers are an option we think but thought that would impact performance because of activity on those tables. Could someone please suggest any other best
options that are possible with SQL Server 2000 to capture these changes.
Thanks,
