Performing Oracle DBA task on Linux OS

Hi,
I an Oracle 9i OCP DBA fresher. I've been performing DBA tasks on windows XP. But, now I wish to switch to linux as dual OS.
Please tell me which distribution of linux would be suitable for me ( I've never used Linux before.). I also wish to upgrade to Oracle 11g OCP.
I think for that up-gradation, I'd have to take 1zo-055 exam. Could anyone help me getting the right material for the preparation of this exam.
Thanks .

Hello Aman,
If you have OCP already and go take teh oca and ocp exam you dont need any further courses or the sql exam as far as i know.i upgraded from ocp 10 g to ocp 11g doing it this way.Mohamed,
The reason that I mentioned your answer as wrong that you suggested the same for a fresh OCA and OCP. The person is exempted from training only if he is going for an upgrade exam not for the complete track which you mentioned in your reply.
Please see the complete track and upgrade path pages which mentions it clearly,

Additional training is not required to upgrade your certification from one version to the next.

Tips required to practice oracle dba tasks on home comp.

hi Guys,
i want to practice oracle dba tasks at home. I am guy just graduated in MS. I want to practice oracle dba tasks on my personal comp. I have oracle on linux installed.
Can some tell me in detail as to what tasks i can do on my personal comp.
it will be great if anyone lists out the tasks in detail that i can do.
there are not a lot of companies who want to hire a junior dba. I guess i am of the view that I will practice what ever i can on personal comp.
detailed answer will be highly appreciated.
Thanks a lot in advance

It's tough to practice at home because you don't really have a dynamic database that changes or experiences abuse like a real one does. Probably the best things to do are to make sure you know the syntax of parameters and views. For example, when you use log_archive_dest do you need yo include the word "location" in your setting? Or is you need to kill a session, what view will you query and what information do you need from that view? IT's always good to know about non-Oracle things too, like how to construct a .cmd file in NT or a shell script in Unix. How do you set up an ODBC driver for a non-Oracle db connection? Make sure you know how to do exports and imports (easy once you've done them a few times but intimidating the first time). Know how to check your database only using DOS commands in NT. Learn vi or another Unix text editor. Have knowledge of how a three and four tier set up works.
When you're first hired as a Jr. DBA you'll probably be doing grunt work that the senior doesn't want - like writing scripts, checking the backups and exports each morning, doing installs, etc. Make sure you know where to look for these things, how to tell if an online backup is successful or if it is stuck in online backup mode. Know OFA compliant locations. Know what and where the OFA ORACLE_HOME is. Know where the tnsnames file is, how to troubleshoot it.
Keep a sense of humor and be humble. Keep an open mind and always keep the attaitude that you can learn something everyday from someone else.
Hope this helps,
EC

DBA Tasks - Industry standard guidelines

Hey :
As a DBA what are the recommended tasks that we should be doing regularly?
- Daily tasks
- Weekly tasks
- Sanitary checks frequency
- Must have documented reports
- What else??
I am looking at putting a system in place for the team. Any industry standard reference and guidelines would be good starting point for me.

Hi,
Any industry standard reference and guidelines would be good starting point for me. Everybody has a differing idea of the DBA job role. I've been a DBA for 25 years, and I would say the main duties include:
Install, patch and maintain all Oracle software
Tune all Oracle instance components including SQL and PL/SQL
Approve all production schema changes
Approve changes to database design
Control all migrations of Oracle schema objects
Design and implement a backup & recovery system
Implement Oracle failover technology
In addition, in some shops the DBA's take-on responsibility for a whole new set of Oracle DBA tasks:
Data modeling and Oracle database design
Data interface protocols
Managing data security
Managing development projects
Predicting future Oracle trends for hardware usage and user load
I have more notes here:

What are all the duies that have to be performed by an oracle dba

hi
i am new to oracle and i want to know the duties that have to be performed by an oracle apps dba?
how many years of exp is required to become an dba?
is it compulsory that i should know plsql to become an oracle dba?
Thank you

There duties of a DBA will vary depending on the job role and to some degree the organization in which you work. There are some core duties that you should be to handle no matter the role. Some of those duties would be:
Backup and Recovery
Backup and Recovery
Backup and Recovery
Database creation
User/schema Management
Database and application (sql) tuning
Knowledgeable of the Oracle process and memory structures
Knowledgeable of the OS being used
Good people skills.
and Backup and Recovery
The above is by no means an exhaustive list, but areas that I look when I am interviewing a DBA. Being an Apps DBA, you will also no doubt need have duties that are centered around the support of the Apps.
The multiple listings of backup and recovery are subtle hint that you should be very familiar with the concept as it applies to Oracle no matter your role.

weblogic server installation is perfect no errors at all.
i also got the errors i got during installation ( im_emagent.mk and while running command gcc) . but thanks to OTN Forums i had managed to find out a fix. but on this error only solution i got is
TRY WINDOWS . but what about linux then? is there any solution on this error?
i am not much used to front-end ( java i mean). i am Oracle DBA Actually n want to install n try Weblogic
Kindly Help...

You can just copy the relevant parts (the ones marked with error). You can also look at the timing
when it happened the reports environment did not start.
From what i remember this could be a memory issue, standard every managed server (WLS_FORMS and WLS_REPORTS) instance
is configured with 1024m bytes of memory.
What we did is first install a forms instance and after that a reports instance. After the forms installation we adjusted the
memory parameters in setWLSEnv (<middleware-home>/user_projects/domains/<domain-name>/bin). Look in this file
for references to WLS_FORMS (something similar to: if [ "${SERVER_NAME}" = "WLS_FORMS" ] ; then).
Another thing which springs to my mind is, which products did you select. If you just want Forms and Reports
you can select just the following:
- Oracle Forms
- Oracle Reports
- Developer Tools aan.
- Management Components
- Oracle HTTP Server
and deselect the other options:
- Oracle Portal
- Oracle Discoverer
- Oracle WebCache
- Clustered (if you are not using clustering)
We also had to fix the following files (i do not think that you have to do this since your Forms did not show any problems):
- (On Windows) Copy the file msvcr71.dll (FMW/windows/extra) to WINDOWS/system32.
- Copy the file mod_wl_ohs.so (FMW/<operating-system>/extra) to <middleware-home>/as_1/ohs/modules.

DBAShell - New Open Source Project for Oracle DBA's

I'd like to have this project included in the Open Source Oracle tools list at: http://www.oracle.com/technology/community/opensource_projects.html
I've been an Oracle DBA for quite some time (since 7.0.13) and a developer for many years. One of the things I've always wished for was an easier way to set up environment variables for different Oracle Homes and a way to provide passwords to scripts without embedding them in plain-view.
About 3 years ago, I started a set of functions and scripts at my company that did exactly just that and provided many more functions for things like checking database status, running scripts quietly unless errors are detected, running actions in parallel (like fast shutdowns at once, or multiple analyzes), restarting databases in a guaranteed fashion, aliases to common folder locations, etc..
About a month ago, after putting all this time and effort into these scripts and using them in production all this time, I realized I wanted more out of the scripts like support for other databases and thought that it would be best if I gave it new life as an Open Source project.
So that is how http://sourceforge.net/projects/dbashell/ was started. Now its in a second release (DBAShell 0.85) that is more modular and would allow other people to easily add support for other OSs, other Shells, and other Databases.
Here is a description of the project from the latest news item:
DBAShell is a project based around Shell functions and scripts designed to make it easy for DBA's to use Databases in a command line environment. Currently supported is Oracle with ksh and bash on AIX, Solaris, Linux. The code base itself is 3 years old and has been in use in Production environments all of that time.
Features include:
* Automatic setting of all environment variables based on SID requested.
* Manage PATH's and other path like variables for each ORACLE_HOME needed.
* Run scripts with stored passwords (no more hard-coding of passwords!!)
* Automatically set SID based on Script location (makes it easier to share scripts between SID's)
* manage temporary script output and check for oracle errors in output
* check database status and versions from scripts
* stop/start databases in parallel (faster startup)
* compile all database objects
* analyze objects in parallel (Faster analyzes)
* set aliases and variables for common SID areas, etc..
* many helpful commands for common Oracle tasks
Over a thousand people have already downloaded the prior release and more are downloading every hour.
I'm seeking feedback from anybody that would be willing to take a look at the project, trying it out, give me any feedback you have on it, and perhaps even direct me to where I could best promote this project.
I wrote a tutorial that shows at a glance some of the more useful features of DBAShell:

Always glad to have people thinking about the poor DBA's. Usually, the developers get most of the attention in open source.

Are the oracle DBa's seeing an end to their career

It's been 2-3 years i am working as an oracle dba in a mid range shop and i was pretty happy with it. After having the satisfaction , I was always worried about the future of an oracle dba. I always heard sql server and db2 are much much better than oracle as they are less complex to administration and their cost is less. Though the oracle people would talk about performance and scalability but with the recent releases , those db have overcome those problems. The problems for oracle dba are coming from several ways:
1.Companies are shifting for sql server or db2 as for low cost and low required of man power.
2.Oracle itself becoming automated.
3. Company like IBM offering main frame solution with free db2 database for the entire data center.
4.With the concept of Cloud computing storage would be third party location , where few employee can take the responsibility.
And..many moreeee...
It gives me a COLD feelings what would i be doing in 3-5 years from now and how could a dba would evolve himself with the change??? I hope this time i am not right.. all the points that i showed is wrong...

This is a common trend and Oracle is leading flagship in it.
Ultimate goal, as I see, is to eliminate DBA, minimizing cost of ownership.
This will attract business to such products - self-managed software.
I do not see it to happen tomorrow, though. But it is going there.
Yeah, well 30 years ago the experts were predicting the end of the need for programmers (the old term for 'developers'). "End User Computing" would put the power in the hands of the business users and eliminate the entire IT department. No I'm not exaggerating. That was the prediction. And people like you were insisting it would come to pass.
You don't even have to go that far. Look at the predictions for the 'paperless office' . . .
Many here will argue with me, but look of the definition of DBA

Implement and maintain database security (create and maintain users and roles, assign privileges).
Database tuning and performance monitoring.
Application tuning and performance monitoring.
Setup and maintain documentation and standards.

Interface with MSSQL/MySQL/Oracle for technical support.
ITIL Skill set requirement (Problem Management/Incident Management/Chain Management etc)
>
Well, that's ONE "definition" of a DBA. It's far from "the" definition.
I'll tell you what. I've actually sat on committees that drew up lists like that. I can tell you first hand that while a lot of things on the list may look legit, there is also a lot of pressure just to fill up the list with as many things as possible in order to justify head count to the bean counters. You could just as well add 'weekly cleaning of the left-hand smoke shifter.'
Then lets look at them one by one:
Installation, configuration and upgrading of Microsoft SQL Server/MySQL/Oracle server software and related products.How often Installation happens? Once for one new app. Usually app vendors have recommendations that DBA should follow. So, what is DBA's role here? Start installer and to follow.
Configuration and upgrading will be more and more automated.
Except the app vendor left out critical details they didn't think were critical because they don't understand the database. Or have bogus 'requirements' because they don't understand the database. Or their recommendations were based on how they did it in their pristine development lab and they never even knew about critical dependencies that might not exist outside of their lab.
Week before last I spent 50 hours working on installing a new database based on the app vendor's specifications ....
Evaluate MSSQL/MySQL/Oracle features and MSSQL/MySQL/Oracle related products.Again, how often? When new App is about to be created and designers need to choose which DB they will need.
And then they proceed to develop on rdbms-A using best practices they learned from rdbms-B -- which turn out to be worst practices on rdbms-A. And only when they go live do they discover that their design doesn't scale because they tried to re-invent (poorly) functionality built into the database.
Establish and maintain sound backup and recovery policies and procedures.Again, how often yo need to establish policies and procedures? Every time you put in a new app with a different SLA.
Backup itself is 100% automated already today. Only if you buy off on the lowest common denominator.
Recovery is close to 100%.Oh? Go spend some time in the RMAN forum ...
And even if it were close to 100%, 'close' only counts "when playing horseshoes or hand grenades."
Most of enterprise backup software support backup and recovery of major RDBMSs.
Just specify a date "from" and click Go.
A little bit complex with RMAN. You have to type(!) RESTORE DATABASE; RECOVER...
Until the cause of failure was something the automation didn't anticipate. Or you then discover that your 100% automated-out-of-the-box backup didn't work the way thought it did. Oh, it 'worked' all right. Just not the way you thought it did.
Take care of the Database design and implementation.Where? Only in development shops.
Depends on what you mean by 'database design and implementation'. And most companies have some sort of development, even if they don't recognize it or call it that.
Implement and maintain database security (create and maintain users and roles, assign privileges).Centralized enterprise security (Domain etc) are in use. Many apps have their security and use basic RDMS security to login App running user.
Until such time as "nothing changed" but "I can't connect to my database".
Database tuning and performance monitoring.Greatly automated. Ultimately will be 100% automated.
Until it's not. See my comment above about developers.
Application tuning and performance monitoring.There are enterprise solutions for monitoring. Also Oracle has Grid Control.
Application tuning can be done by app vendors.I've NEVER met an app vendor that knew **** about how their app impacted performance. 100% of them throw it back on the DBA. I had an app vendor tell me that Oracle was incapable of sustaining more than five concurrent connections.
DBA cannot tune App itself. It may only modify some things in DB that will perform better. And this will be automated.
No, because the database cannot anticipate what stupid things the vendor may do. And it can only work with what it is given.
Setup and maintain documentation and standards.How often?
As often as anything that is documented, changes. As often as it is discovered that something that should be documented, isnt'
Plan growth and changes (capacity planning).Well, DBA should do it. But, again, how often?Should be almost constantly. Given budget cycles, you can't wait until your disk is 98% full before asking to buy more.
>
Work as part of a team and provide 7×24 supports when required.Where such 7×24 support policy exists.Look at my comments above about how these lists get created in the first place.
I can tell you from experience that such 24x7 policies are more common than you seem to think. Just about any financial processing business, logistics and transportation business, telecom business ...
And what from above should be supported during a night by a human?
I see just a restore/recover DB, because a human should make a decision "From which Date".
Do general technical trouble shooting and give consultation to development teams.Yes, in Dev shops. Most of shops are not development shops, though may do custom and ad-hoc reporting and small app development. Do they need a dedicated DBA for this? I doubt. Either a developer will be (self)trained to do some DBA's tasks or DBA will become a SQL developer in that team.
Interface with MSSQL/MySQL/Oracle for technical support.Oh yeah... :)
ITIL Skill set requirement (Problem Management/Incident Management/Chain Sure, two days of training to know basics of ITIL to understand what manager of Helpdesk (Support and Incident Management Team) is talking about.
So, I see DBA should go in of 3 directions:
1. Very deep technical expert that can help in some rear and difficult cases. How many of them will be needed?
2. SQL/ETL/etc Developer. There is not much automation in software development yet.
3. DB Design and Architecture. How many of them will be needed? May be more that #1.You seem to think that automation will solve everything. Take that to it's logical conclusion and it will put all of IT out of work. See my comment above regarding "End User Computing'. What you forget is the human element. Not the human DBA trying to do things you think are or soon will be automated. No I'm talking about the humans that create the kinds of problems that automation is *always* trying to catch up with. Pointy Hair Bosses dreaming up new requirements. Bean counters refusing to by an additional 10 gb of disk. Developers that refuse to learn and/or follow best practice. Developers that can't think beyond clicking an icon to create a table. Developers that treat an rdbms as a data dump and try to use Java to re-invent every bit of functionality the db already provides. Systems administrators that delete all of your online redo logs because he needed disk space and 'log files are expendable'. End users that forget their password *EVERY F****** DAY!*
No, I don't spend my time managing extent distribution like I had to do with 8i. Yes, a lot of things I had to do manually in 8i are now successfully automated to the point I don't have to do them .. or have simply been engineered out of the system. But no amount of automation will overcome the ways humans (Executives, managers, supervisors, other IT team members, and users) figure out how to bring a system to its knees.
This whole discussion reminds me of Dippin' Dots. "The Ice Cream of the Future". Well, it's been "The Ice Cream of the Future" for almost 30 years ....

Oracle 9i client for linux & PHP

I'm looking to connect PHP on my linux server to a remote oracle server running 9i. I have been unsuccessful in finding good documentation on this process, as most people are either using windows or connecting to a local server.
As far as I can tell, you must install the oracle client for linux, then recompile PHP with oracle support. So:
1) Is this the best method to do this, and if so where can I get an oracle client for linux?
2) Is there a location where I can get the oracle extension for PHP without having to recompile PHP?

I believe the extensions are refered to in the php.ini
and need to be setup.
;Windows Extensions
;Note that MySQL and ODBC support is now built in, so no dll is needed for it.
extension=php_oracle.dll
;Don't know if this is needed and whether there is a
;php_oci9.dll
;extension=php_oci8.dll
which can be found by this:
extension_dir = "C:\WINDOWS"
I am trying to perform a similar task, well, sort of. I am running Oracle 9i (9.2.0.1.0) on a Win2003Server machine and do not want to build PHP either.
Please let me know if you find your answer.
Thanks

Oracle DBA with UNIX

Hello,
I am learning oracle DBA,
Is it necessary DBA should know UNIX?
If it's DBA need to know UNIX shell scripting level or UNIX ADMIN level?
Thanks,Kannan.K

Hello,
I am learning oracle DBA,
Is it necessary DBA should know UNIX?r.- Yessssssss. More that 80% Oracle Production Databases are on Unix/Linux
If it's DBA need to know UNIX shell scripting level
or UNIX ADMIN level?r.- Not a lot but whether you have that kind of knwoledege you could automatize more the daily tasks.

Differences between Oracle 8i for a UNIX Platform and Oracle 8i for a Linux Platform

Hello,
J would like to know if there are some differences between Oracle 8i for a UNIX Platform and Oracle 8i for a Linux Platform.
I know that there are some differences on Oracle 8i Parallel Server and i know that some products are not include like precompiler (Mod*Ada, Pro*FORTRAN) on a Linux Platform.
Thank you.

We have installed Oracle 8i on Solaris 8 and it had a great performance, of course that the hardware and licence invested here was costed my the office where i work. Personaly i'd installed linux reh hat 8 and oracle 8i, imagine that, it could be implemented by any individual that has the time to do so.
By buyinng from a company that has a good background you could be sure that you will have support.
Bottom line, if you have the $ to buy great hardware go for a unix platform. But if you don't a Red Hat Linux Server Licence with a 1 year sopport and Oracle data base is about 3500Dls.

Thank you

Hi,
Are you installing from Software CD?
If you have downloaded it from the OTN, check the size of Software. This error is thrown when the downloaded software is not proper or corrupted.
Try downloading the compatiable OS specific software again. Check the size of the software and install it again.
