Taking perriodical backup of the database server

Hi,
I am new to DBA activities.
I am working on 11.2.0.1.0 version in Oracle.
My database keeps on growing so as a security measure, I am asked to take backup of the databse periodically without shuttingdown this databse. Since this task has to be done periodically, I have to schedule the job for this task.? I know how to take export of the database.. but not sure about the periodical backups... Now sure how to proceed on the activity, so please guide me on the same.
Thanks

ThanksWhy you close the database while taking backups? Use RMAN and take online backups. Schedule it using either DB or scheduler
Check http://tahiti.oracle.com for more information
You can also check my Backup and Recovery video tutorials and see how RMAN works

Which job is taking log Backup of specific database using command?

In my SQL Server there are around 200 jobs of different databases for backup.
Which job is taking log Backup of specific database using command?
Kindly help.
Thanks

Hi,
Its generally a bad design to create different jobs for different databases expecially backup and restore if you create you give specific names to the jobs otherwise it would be difficult for you to track. below query will give you littlt help but if you
are running a proc to backup log files and that proc is situated in master database it wont help. If you are running SSIS package it wont help
The column database name will help you in locating the DB name for which job is running
use msdbgoselect sj.name,
sj.description,
jst.database_name,
sj.date_created,
sj.date_modified,
jst.step_name,
jst.command

Hi all,
I had the exact same problem
the backup menu item runs :
C:\oraclexe\app\oracle\product\10.2.0\server\BIN\backup.bat
when you look at this batchfile you will see the following :
The script assumes that user can connect using "/ as sysdba"when you have OS authentication disabled the batchfile will give the formentioned error
turn OS authentication back on by changing C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN\sqlnet.ora
(you could turn it back off after your backup succeeded)

MDM adapter : what is meant by the database server ?

Hi all,
we are testing MDM adapter on PI 7.1 (no eHp). The adapter config requires an MDM server but separately a database server entry as well.
Does anybody have a working MDM adapter ? if so, what did you fill in in the "database server"
parameter of the adapter ? is it a URL ? JDBC name ? JNDI name ? IP address ? and to which database ? Í'm assuming the database of the MDM server, but that one is installed on the MDM server
(for which we configured an IP address in the "mdm server" field).
additionally, can somebody explain the reason for that separate Database config parameter ?
I have found no explanations in the documentation so far.
Regards,
Ronald van Aalst

Hi,
MDM uses internally Data base Server, MDM is like one Data Base where we can store master Data.
when you are trying to connect to MDM using MDM-PI Adapter, you have to Give all details like port number,server details,
please read don about MDM Documetation about MDM-PI Adapter.

Conflict resolution manager having which spid at the database server.

Folks,
I've come across a situation where in one of the
1.SID was generating high redo SID - 1098 .
2.when i checked what this sid was doing - i figure out that it belongs to a report set, still having the sid at the database server.
3.The client process id(12041) of thie SID(1098) is shown as the spid shown in the system column at system administrator --> concurrent manager --> Administer --> Highlight conflict resolution manager --> click processes.
4. I understand that we need to grep for the osporcess "ps" using spid and not using "client process id" (process from v$session). Please clarify.
5.when I grep for 10241 it is indeed pointing to CRM process. but when I query for spid (12055) associated with sid (1098) it points to a Reports set which completed error and generating some kind of redo ( which triggered all the above questions).
6.Now the question is should we be checking for SPID (120550) associated with SID(1098) which says (LOCAL=NO) and safe to kill. as the status of the SID says inactive, though the last_call_et is just showing 1.
Thanks in advance.

Can't connect to the database server from localhost

Hi,
I'm having a problem I hope you can help with please!
I recently installed mysql and phpmyadmin... I can access mysql perfectly from the command line, and can access it partially through phpmyadmin although there are some restrictions that I haven't figured out how to change yet (despite editing php.ini, configure.inc.php and others), but on the whole inside phpmyadmin I can see all the databases I've uploaded with the command line and all the users are there and can be edited. Unfortunately whenever I try to connect to a mysql database using a username and password that was created in phpmyadmin (or anywhere!), I get a 'cannot connect to the database server error'. I've checked and rechecked the username, the passwords, the database names and the host names a thousand times but nothing I change is working.
Is there a special prefix my mac could be adding to the database, usernames or host names?
Thanks!

Okay, don't worry!
I finally figured it out...
it needed to be 127.0.0.1 rather than localhost!

Sending Mail Notification From the database server

Hi All,
I want to send the mail notification to any email id from the database server.
I used the in built Package UTL_SMTP(pp_to,pp_from,pp_subject,pp_hostname) but i didn't got the success. Actually i dont know how and what parameters has to pass to this package .
It will great help if some body helps with the an example.
Thanks in Advance

The easiest is to use UTL_MAIL - available from 10g onwards. If you're on 11g, you also need an ACL (Access Control List) entry to allow PL/SQL code to step outside the database and connect to an external server.
UTL_MAIL uses UTL_SMTP. You can use UTL_SMTP directly, but then you need to understand the SMTP protocol and how to correctly construct Multipurpose Internet Mail Extensions (MIME) e-mail bodies. Not difficult - but something that many developers seem insistent to remain ignorant about.

Solving "COMMIT business rules" on the database server

Headstart Oracle Designer related white paper
"CDM RuleFrame Overview: 6 Reasons to get Framed"
(at //otn.oracle.com/products/headstart/content.html) says:
"For a number of business rules it is not possible to implement these in the server
using traditional check constraints and database triggers. Below you can find two examples:
Example rule 1: An Order must have at least one Order Line ..."
But, one method exists that allows solving "COMMIT rules" completely on the database level.
That method consists of the possibility of delaying the checking of the declarative constraints (NOT NULL, Primary Key, Unique Key, Foreign Key, Check Constraints) until the commit
(that method was introduced first in the version 8.0.).
E.g. we add the field "num_emps" to the DEPT table, which always has the value of the number
of the belonging EMP rows and add DEFERRED CK which uses the values from that field:
ALTER TABLE dept ADD num_emps NUMBER DEFAULT 0 NOT NULL
UPDATE dept
SET num_emps = (SELECT COUNT (*) FROM emp WHERE emp.deptno = dept.deptno)
DELETE dept WHERE num_emps = 0
ALTER TABLE dept ADD CONSTRAINT dept_num_emps_ck CHECK (num_emps > 0) INITIALLY DEFERRED
Triggers that insure the solving of the server side "COMMIT rules" are fairly simple.
We need a packed variable that is set and reset in the EMP triggers and those value
is read in the bur_dept trigger (of course, we could have place the variable in the package
specification and change/read it directly, thus not needing the package body,
but this is a "cleaner" way to do it):
CREATE OR REPLACE PACKAGE pack IS
PROCEDURE set_flag;
PROCEDURE reset_flag;
FUNCTION dml_from_emp RETURN BOOLEAN;
END;
CREATE OR REPLACE PACKAGE BODY pack IS
m_dml_from_emp BOOLEAN := FALSE;
PROCEDURE set_flag IS
BEGIN
m_dml_from_emp := TRUE;
END;
PROCEDURE reset_flag IS
BEGIN
m_dml_from_emp := FALSE;
END;
FUNCTION dml_from_emp RETURN BOOLEAN IS
BEGIN
RETURN m_dml_from_emp;
END;
END;
CREATE OR REPLACE TRIGGER bir_dept
BEFORE INSERT ON dept
FOR EACH ROW
BEGIN
:NEW.num_emps := 0;
END;
CREATE OR REPLACE TRIGGER bur_dept
BEFORE UPDATE ON dept
FOR EACH ROW
BEGIN
IF :OLD.deptno <> :NEW.deptno THEN
RAISE_APPLICATION_ERROR (-20001, 'Can''t change deptno in DEPT!');
END IF;
-- only EMP trigger can change "num_emps" column
IF NOT pack.dml_from_emp THEN
:NEW.num_emps := :OLD.num_emps;
END IF;
END;
CREATE OR REPLACE TRIGGER air_emp
AFTER INSERT ON emp
FOR EACH ROW
BEGIN
pack.set_flag;
UPDATE dept
SET num_emps = num_emps + 1
WHERE deptno = :NEW.deptno;
pack.reset_flag;
END;
CREATE OR REPLACE TRIGGER aur_emp
AFTER UPDATE ON emp
FOR EACH ROW
BEGIN
IF NVL (:OLD.deptno, 0) <> NVL (:NEW.deptno, 0) THEN
pack.set_flag;
UPDATE dept
SET num_emps = num_emps - 1
WHERE deptno = :OLD.deptno;
UPDATE dept
SET num_emps = num_emps + 1
WHERE deptno = :NEW.deptno;
pack.reset_flag;
END IF;
END;
CREATE OR REPLACE TRIGGER adr_emp
AFTER DELETE ON emp
FOR EACH ROW
BEGIN
pack.set_flag;
UPDATE dept
SET num_emps = num_emps - 1
WHERE deptno = :OLD.deptno;
pack.reset_flag;
END;
If we insert a new DEPT without the belonging EMP, or delete all EMPs belonging to a certain DEPT, or move all EMPs of a certain DEPT, when the COMMIT is issued we get the following error:
ORA-02091: transaction rolled back
ORA-02290: check constraint (SCOTT.DEPT_NUM_EMPS_CK) violated
Disvantage is that one "auxiliary" column is (mostly) needed for each "COMMIT rule".
If we'd like to add another "COMMIT rule" to the DEPT table, like:
"SUM (sal) FROM emp WHERE deptno = p_deptno must be <= p_max_dept_sal"
we would have to add another column, like "dept_sal".
CDM RuleFrame advantage is that it does not force us to add "auxiliary" columns.
We must emphasize that in real life we would not write PL/SQL code directly in the database triggers, but in packages, nor would we directly use RAISE_APPLICATION_ERROR.
It is written this way in this sample only for the code clarity purpose.
Regards
Zlatko Sirotic

Zlatko,
You are right, your method is a way to implement "COMMIT rules" completely on the database level.
As you said yourself, disadvantage is that you need an extra column for each such rule,
while with CDM RuleFrame this is not necessary.
A few remarks:
- By adding an auxiliary column (like NUM_EMPS in the DEPT table) for each "COMMIT rule",
you effectively change the type of the rule from Dynamic (depending on the type of operation)
to a combination of Change Event (for updating NUM_EMPS) and Static (deferred check constraint on NUM_EMPS).
- Deferred database constraints have the following disadvantages:
When something goes wrong within the transaction, then the complete transaction is rolled back, not just the piece that went
wrong. Therefore, it becomes more important to use appropriate commit units.
There is no report of the exact row responsible for the violation nor are further violations either by other rows or of other
constraints reported.
If you use Oracle Forms as a front end application, the errors raised from deferred constraints are not handled very well.
- CDM discourages the use of check constraints. One of the reasons is, that when all tuple rules are placed in the CAPI,
any violations can be reported at the end of the transaction level together with all other rule violations.
A violated check constraint would abort the transaction right away, without the possibility of reporting back other rule violations.
So I think your tip is a good alternative if for some reason you cannot use CDM RuleFrame,
but you'd miss out on all the other advantages of RuleFrame that are mentioned in the paper!
kind regards, Sandra

HOW DO I KNOW IF THE DATABASE SERVER IS RUNNING?

Hi guys,
How do i write a java code to determine if my database server(s) (eg : Oracle or mySQL or postGRESQL, msSQL etc) are (is) running.
I want to know how to code in java to determine if a certain database server is running when i start the java application .
Thanks for your help

Acquire a connection. If it doesn't throw a SQLException, then you can be certain that the database is up and running.

Save a report 6i PDF file onto the database server

Hello Experts,
I have a requirement, whereby I need to generate a PDF report and then send that report via Email. The problem I have is my email procedure is looking for the file which is in the directory on the server where the database is stored, While the PDF is generated on the local machine. Im using reports 6i.
I know in reports 10g the file is generated on the report server itself but Im afraid same is not the case with reports 6i.
The other problem is the local machine does not have the access to the directories on the server. I tried to change the directory path in the database to look at the C:\ but it doesn't work, it says invalid directory, I think the PDF report file needs to be on the server where the database is installed. Is there a way I can pick the PDF file from the local machine instead of the server where the database is installed?
Im not too sure what is the way forward, All I need is to generate a PDF file and mail it.
The procedure that I'm using to send the email attachment is :-
CREATE OR REPLACE PROCEDURE email_attachment(
xfilename VARCHAR2,
xloc VARCHAR2) IS
conn utl_smtp.connection;
BEGIN
conn := Send_Mail.begin_mail(
sender => '[email protected]',
recipients => '[email protected]',
subject => 'Attachment Test',
mime_type => Send_Mail.MULTIPART_MIME_TYPE);
Send_Mail.attach_text(
conn => conn,
DATA => '<b>This is a test Email.<b>',
mime_type => 'text/html');
send_mail.attach_base64_fromfile(
conn => conn,
filename => xfilename,--'test.pdf',
floc => xloc,--'File directory',
mime_type => 'application/octet',
inline => TRUE);
Send_Mail.end_attachment( conn => conn );
Send_Mail.end_mail( conn => conn );
Thanks any help would be appreciated.

Hi,
in the forms 6i email with attachment can be sent only through database folder/file. From the client it can not be.
Here is one alternate solution.
1. Share the folder from db server which is used for email directory and keep changeable for everyone.
2. After generate the report like RUN_PRODUCT keep the below command.
HOST('XCOPY CLIENT_PATH\FILE_NAME SERVER_PATH');
3. This command will transfer file from client to db server. After this execute your procedure which is sending email.
Hope it will work.

Connection not closed in the database server end

Hi,
Our database server (sql server 2000) and java application are running in two different boxes. Because the java application sent to the db server quite a few queries that can not be completed (applications hangs there) due to huge amount of data (18 million records in one table and 1 million records in another table and there are joins among the three tables), we stopped the java program. However, in the db server end, the connections associated with these problem queries were not closed although the java app end already closed these connections by calling connection.close(). When this happened, we have to manually close the connection from sql server enterprise manager.
Here are the questions.
1)what could be the reason why db server does not close the connection?
2)Is there any solution in the java end that could close the connection in the db server end when this situation happens? I say this situation happens, I mean in most cases when java application closes connection, db server closes connections in its end too.
Thanks
Mark

Thanks for your answers and questions.
Here are the answers to your questions
1)The jdbc driver is jturboJTurbo? Never heard of it. You mean this?
http://www.newatlanta.com/products/jturbo/index.jsp
Why pay for something when you have two options available that are free? One of them is from Microsoft itself. Whose idea was this?
2)It's a desk top application.
It seems to me that it should not be driver issue. I was this happened the Microsoft's own jdbc driver. By jdbc specification, although you don't close the connection explicitly in the program, the connection will be automatically closed in the java app end during garbage collection. Very bad - never depend on this. Always close your ResultSet, Statement, and Connection in reverse order of opening in a finally block, each one wrapped in individual try/catch blocks.
One should never, ever depend on the GC to take care of resources like database connections or resource handles. Those should be cleaned up by your code.
I tested this by intentionally not closing a connection. When I stops the application, the connection in the sql server end was also closed.
But if you don't close the application and fail to close connections, you can see where eventually you'll exhaust the pool.
It seems to me this is a sql server issue rather than a jdbc driver issue. I need way to prove this.
Like I suggested, it's easy to swap in the jTDS driver and try it again. What do you have to lose?
Or call Microsoft support and ask them. Or maybe JTurbo. You're paying for it - might as well use the support.
