Database administration.
I dont have any database experience and I would like to start with a possible out come to become a database administrator not necessarily a programmer. As you can imagine what I would appreciate is any information on where to start with Oracle databases administrator since they are considered a stable and reliable products. Books either online or by purchasing them, opinions etc. are most welcomed. I have a background in programming with Java and system administrator but not with databases. To that end, any help on how to proceed to my database learning venture even as to suggest that I could get the OCA certification, after seeing the cert paths of Oracle would be appreciated.
First step was the right step, forum participation. You can post here all your requests, questions, setup, configuration, references, and answer are at a very high level.
I would suggest you this:
. Download Oracle RDBMS software, you can start easy with the Oracle XE edition, it is lightweight and very easy to setup and use. For advanced features you may want to use the Enterprise Edition.
. Download de SQLDeveloper, it will provide you a very good tool to access, database.
. Download the manual to have it handy in case you require it and you are offline.
. Start with the two-days dba manual http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14196/toc.htm and start practicing from here
. Once you are involved with this dba topic you can proceed to specific points, as described at the Certification Exam Guide. This way you'll start getting involved with very specific aspects of database administration and you'll be preparing for the OCA exam at the same time.
. Practice - practice - practice ... and ah! keep practicing.
. Questions, issues, and so on, we all here will be gladly to answer.

Hi Gurus,

After to make changes effective, i stopsap & startsap.
But unfortunately db is not coming up. I checked startdb.log it showing
error as " ASE instance not available
*** ERROR:ASE instance possibly left running when system
went down(system crash?).
Notify Database Administrator."
Please help us to resolve this issue, i have also added startdb.log for
your reference.

How to apply row level security against the database administrator
I would like an advice in applying row level security against the database administrator. We need to prevent DBA from editing data in some table rows or have any indication that data was corrupted.
There is no problem in viewing the data so we considered one way hash function or digital signature which will be stored in the same table, but we see following disadvantages:
HASH - DBA may use the same hash function to update the stored data after he changes the sensitive row.
Digital signature - the is a need to manage and keep the private key in a safe place outside of DB
Is there additional ways to achieve the aim?Does VPD helps to prevent from DBA to edit/view a data in specific rows?Yes.
If I correctly understand, DBA has full access to security policy used by VPD to control the access and can grant himself privileges that I don't want.You can to define which users can be exempt of the politics, for the context or by Grant EXEMPT.
This includes DBAs.
The simple fact of being DBA doesn't guarantee the exemption.
Everything goes to depend of the VPD config. -
Career from Systems to Database Administrator
Hi all,
I need some career advice. I want to persue my career as an Oracle Database Administrator and I have underwent a basic level of training on Oracle Database administration.However, I have been recently moved to a team which is into -- systems. And my work is mainly related to Active Directory,Exchange and managing servers.
I searched a lot about -- 'starting the career as an Oracle DBA' and found out that people generally start as Systems Admin/Unix Admin/Developer and then switch to DBA Admin. My work experience is less than 1 year. I would like to know-- should I continue with this Systems work and get some experience in System Admin to get into Oracle DBA Admin?
If so,then for how long should I continue with Systems before actually switching over to Database Administration? Moreover, should I do some certifications like MCSE while I am working in Systems? And when and how should I start my preparation for Oracle certifications?
Hope to get inputs from you all.
Thanks in advanceyou have to have some earnings, if you are already at another area, you can take adavantage of being already hired somewhere, and you can start studing in parallel so you get acquinted with oracle. First kind of job you may find is a DBA at entry level, which lets you in a pretty difficult position, but there is no other way to start.
Download software and manuals and start practicing as much as you can. A lot of peaple I have seen here at entry level have taken this strategy:
- continue with current job
- start self-studing oracle from manuals
- installed oracle at a local pc/laptop (XE or EE)
- a lot of questions, lack of concepts, problems, bad configuration appear
- they take advantage of this forum to start troubleshooting and continue learning
- when they feel more comfortable with knowledge the make the OCA exam and later on OCP.
- either way, keep studying

Warning in DB13 Check DB "BR0970W Database administration alert"
Hi
We have an alert message in DB13 when we check the checkdb log. Log details are as below
BR0970W Database administration alert - level: WARNING, type: CRITICAL_FILE, object: /oracle/EPR/sapdata10/btabd_11/btabd.data11, value: (max_size) 30466040 KB (> 29439485 KB)
This warning is for all the datafiles; I did just give the sample log above.
Can you please suggest and help resolving this issue?
Thanks in advance.Hi,
The issue here is that there is no enough disk space for the datafiles to extend. In this case you can turn off the auto extend or Increase the disk space of sapdata10 or decrease the max_size or you can move some of the datafiles to other directory or filesystem.
You can turn off the auto extend while the database is online. After turning off the auto extend, you need to monitor the datafile/tablespace size periodically.

I checked in SE14, the table VCSMONITOR is Transparent table and the Status is "Not Actve" (Exists in the database).
List of all indexes (constraints) of the table
Index name Unique Short description
0 X Primary index
There are no secondary indexes
Checked for this table/objec in ECC/SRM/BW systems, in SE14 it reports as "object does not exist".
Could you guide me further please.

Oracle 10g Database Administration Workshop I
Dears !
How i may get a soft copy of the Oracle 10g Database Administration Workshop I from the net for downloading in free.
Thanks.Ashraf,
Besides the fact that the soft copy is and only is to be used by Oracle University trainers and is a properity of Oracle and that's make the use of it outside oracle illegal if you are not a part of OU, I would say one more thing.If you are really on the level to start with oracle database administration learning which seems to be true from the request you made,you wont be able to clear ANY doubt from the book alone. You need some one to have a talk/discussion to clear them and thats why its called ILT,instructor lead training. There is no use at all of the book if you don't get the doubts clear and I can gurantee that by juse reading the book,soft/hard whatever copy,you wont get anything.So it better to come in OU and do a proper course.If you think price is the issue than you can do the same from a partener too where price would be less as well.

Before anything thanks to everybody that contribute on this forum.
May you introduce me book or document for start on Oracle database administration?
Thanks in advanceBesides the 2-Day dba guide, you should have a read of the Concepts and Administrator guide from the docs at http://tahiti.oracle.com . In addition, read these following books as well,

Java certification & oracle database administrator certification
Hello,
On this page i can see all certification paths. But when i logged into my account, on pearsonvue.com, i issued 'Schedule an exam'. But there i can't find any java certification or oracle database administration certifications. So where can i find all the certifications for scheduling, shown on that page?

Thanks1) You need to drill down from that link to find individual exams ... eg 1z0-051, 1z0-052, etc ... for instance via:
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=198&p_org_id=&lang=
http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_exam_id=1Z0_052
2) You may need to register on Pearson VUE particularly for Oracle.
(Prometric works much on on a one registration does all, Pearson VUe requires registration for each vendor, in general as far as I remember). But I was able to use my LPIC registered Pearson VUE for Oracle
To begin with ensure you go via http://www.pearsonvue.com/oracle/
3) Java exams, having come from Sun stewardship, are currently via Prometric.
See the Sun Transition FAQ (which is now VERY hard to locate unless you know what you are looking for!)

Few basic questions about database administration
Hello,
I have a few basic questions about database administration.
1. I switched one of my oracle instances to archivelog mode. I just cannot locate the archive log files on my windows system. The %ora_home%/ora92/database/archive directory is desperately empty...
2.What is the tools01.dbf datafile used for?
3.What is the undotbso1.dbf datafile used for?
Thanks in advance,
Julien.1. The archive log location needs to be specified in your init.ora file. By default, Oracle will place the archive files in either ORACLE_HOME/dbs or ORACLE_HOME/database.
2. The tools01.dbf file belongs to the tools tablespace which should be set as the default tablespace for system. It primary purpose is to hold Oracle Forms and Reports database objects, however, it should also be used for holding other non sys database objects such as the perfstat (statspack) or other third party database schemas e.g. quests sqllab.
3. undotbs01.dbf file belongs to the undo tablespace. -

Message was edited by: Antonio
user514311Have you read the Oracle documentation? That is the always the best place to start. The Concepts guide first, then either the SQL ref or the the Admin guide. But don't succumb to the temptation to skip the Concepts. we all need to understand the basics.
