Configuring Oracle for learning purpose in Laptop

Hi all,
I would like to configure Oracle11g in my laptop for learning purpose. Basically i would like to learn PL-SQL by creating some stored procedures and playing around that. Could you just tell me as to how to simulate a pl-sql development environment in home laptop?
Thanks in advance

Please clarify what you are referring to as OEM and Rapid Sql.
If by OEM you mean Oracle Enterprise Manager Database Control, a database management console, then you would need one of the "full" editions not XE. I believe you may install and use even Enterprise Edition with a for-free license, as long as it is for pure learning purposes/self-education. See what it says about the OTN license in the top of the [url http://www.oracle.com/technetwork/indexes/downloads/index.html]downloads index page.
For SQL development tools in general, XE should do fine as long as you build apps within its feature set.

Installing Apps for learning purpose

I want to install Oracle Apps for learning purpose and I have few questions:
1. What version is preferred 11i or 12?
2. What operating system should I use?
3. Where can I find the installation?
4. Could I install it for learning without purchasing a license?
Thank you.

1. What should I download for starting? I understand that all the rapid install disks, is it right?If you select "Oracle® Applications 11i Release 10.2 Media Pack for Microsoft Windows" then you need to download all the zip files belonging to the following parts:
- Rapid Install Start Here
- Rapid Install RDBMS
- Rapid Install Databases
- Rapid Install Tools
- Rapid Install APPL_TOP
In addition, if you wish to install any language other than American English, download the Rapid Install NLS Disks for the corresponding languages.
2. What is the use of each part? For example there are three Databases disks.You need to use all the disks mentioned above. Each set will be used to install a component like Oracle Database technology stack, APPL_TOP, Oracle Applications technology stack .. etc
3. Is the demo company (VISION) included in the files? Yes. At the time of the installation you can select to install either a production/test database or a vision demo database, all are included in the same media kit.

How different is Enterprise Linux compared to Fedora?To add Sergio's post, Fedora and Enterprise Linux are based on RedHat distribution. Fedora is non commercial distribution and is very popular. Enterprise Linux is quite new (name of distribution) in the Linux world (announced at the end of october) and it is clone (as Sergio said) of RH EL 4 U4.
All I need is an opportunity to learn Unix/Linux.Any of Linux distributions will give to you this opportunity. And for learning of Linux Fedora is good enough.
Is Enterprise Linux more popular?
Popular than what? Fedora? It is too soon... (IMHO). Enterprise Linux is ideal candidate for productions systems which needs official support and (of course) systems which where Oracle products will be running on. In this scope (commmercial sphere) Enterprise Linux will become popular than Fedora (which has support only from volunteers) but I don't think that Enterprise Linux will be more popular as Fedora at all...

Configure oracle for external procedures

Help configuring PulseAudio for 2.1 on laptop [SOLVED]

Hello
I've been trying to figure out how to properly configure PulseAudio for my laptop for the past couple of nights, but haven't had much luck. I'm may be misunderstanding my laptop's audo setup correctly. Seeing stuff like True 5.1, Dobly Home Theater, and Virtual SurroundSound confused me, but right now I think 5.1 is only for HDMI output (which I don't use). My laptop has a so-called subwoofer and in alsamixer I have controls for front and lfe.
By default, pulseaudio chooses stereo, which sounds fine for anything that stereo or mono, but if I play a DVD in VLC I can barely hear voices and but hear parts of music and background sounds.
Also, for some reason if I run speaker-test -c 2 -t wav. Front-left is loud and somewhat distorted while Front-right is really soft. Yet it still sounds fine (to me) when listening to non-surround content.
Everything worked perfectly before pulseaudio was pulled in.
I tried following this post on manually loading the alsa sources and sink modules, but it didn't work.
Running pulseaudio in verbose mode showed that hw:0 doesn't support 3 channels and then defaults to stereo.
default-sample-channels = 3
default-channel-map = front-left,front-right,lfe
I also just tried the above in daemon.conf just to see what would happen but, it ignored it...
What am I doing wrong? Am I going about this the wrong way?
Any help would be much appreciated.

Update.
I got vlc to work right. Yay!
I deleted my .vlc directory
Then, manually set the output to alsa (and set Device to Default) which then ungrayed the Audio > Audio Device menu to select Stereo
edit:
I noticed I loose audio in VLC if I pause or seek around too much... Work around for now is to disable and reenable the audio.
looking with pavucontol vlc is still there, it just doesn't do anything.
anyway, this new problem is probably for a different thread

Mini Project or case studies on oracle for practice purpose

Hi Experts,

Take any real time problem and try to create your own schema for that.
Start with your own requirements and then build it using Oracle.
Search engine for example.

Hope this helps:
The following link is incorrect:
http://bernal/stage/docs61/adminguide/utils.html#1143071
1st)
In the doc it says "The directory containing your WebLogic Server
installation. For example, d:\beaHome\wlserver6.1. Required only if using a
BEA-supplied JDBC driver."
it should say "The directory containing your WebLogic Server License. For
example, Z:\bea\610sp1 .... "
The key here is that if WL_HOME=Z:\bea\610sp1load8c\wlserver6.1 bea.home is
generally but not always one directory above WL_HOME. bea.home should point
to the the bea license file.
2nd)
java -Dbea.home=WebLogicHome utils.dbping DBMS user password DB
//* WebLogicHome is almost never correct(unless the license file lives
there
which it never does, especially out of the box install.. and with multiple
installation the license file could live in a different directory structure
all together) please come up with a new convention for defined bea.home.
3rd)
Please so a "real" sample with a successful result: like the following
Z:\bea\610sp1load8c\wlserver6.1\config\docDomain>java -Dbea.home=%WL_HOME%\.
-Djava.library.path=%WL_HOME%\bin\oci817_8
utils.dbping ORACLE pet112 pet112 pet112
Starting Loading jDriver/Oracle .....
**** Success!!! ****
You can connect to the database in your app using:
java.util.Properties props = new java.util.Properties();
props.put("user", "pet112");
props.put("password", "pet112");
java.sql.Driver d =
(java.sql.Driver)Class.forName("weblogic.jdbc.oci.Driver").newInstance();
java.sql.Connection conn = d.connect("jdbc:weblogic:oracle:pet112",
props);
// This mode is superior, especially in serverside classes because
// it avoids DriverManager calls are class synchronized, and will
// bottleneck any other JDBC in the server, even already-running
// connections, because all JDBC drivers use DriverManager.println()
// to log info and exceptions, and that call is also class synchronized.
// For repeated connecting, a single driver instance can be re-used.
**** or ****
Class.forName("weblogic.jdbc.oci.Driver").newInstance();
java.sql.Connection conn =
Driver.connect("jdbc:weblogic:oracle:pet112", "pet112", "pet112");
**** or ****
java.util.Properties props = new java.util.Properties();
props.put("user", "pet112");
props.put("password", "pet112");
props.put("server", "pet112");
Class.forName("weblogic.jdbc.oci.Driver").newInstance();
java.sql.Connection conn =
Driver.connect("jdbc:weblogic:oracle", props);
4th)
Please show a common mistake and how to correct it: like
Z:\bea\610sp1load8c\wlserver6.1\config\docDomain>java -Dbea.home=%WL_HOME%\.
utils.dbping ORACLE pet112 pet112 pet112

*In order to correct this add -Djava.library.path=%WL_HOME%\bin\oci817_8
or add %WL_HOME%\bin\oci817_8 to your path **THIS IS ONLY FOR WINDOWS**
For solaris -Djava.library.path=$WL_HOME\lib\solaris\oci817_8 or add that
directory to LD_LIBRARY_PATH Also we should documenent the requirement for
oracle libraries be available on the PATH or LD_LIBRARY_PATH otherwise it
won't work.
5th)
Please show what is expected when the user enters this information into the
console... The whole reason for this utility is to help the user with
problems that he/she is having with JDBC pools/datasources from the console.
Idealy a screen shot with the information as it would look from the console.
And tell what they need to do to there Weblogic startup scripts in order for
it work..
6th)
For Oracle Type 2 the following is not true. "DBNAME is the name of a
database on the DBMS." It is the name defined into tnsnames.ora file that
maps to particular DBMS. Also we should provide instructions on how to not
have to rely on the tnsnames.ora file like:
("jdbc:weblogic:oracle:(DESCRIPTION= (ADDRESS = (HOST = suncom) (PROTOCOL =
tcp) (PORT=1521)) (CONNECT_DATA = (SID = ORCL805)))","scott","tiger");
Please let me know if you have any questions...

Hi friends,
i have installed oracle db using Oracle Developer Day.ova for practicing on my lappie.
I want to connect to that DB which is inside oracle vm virtual box manager using PUTTY ( which is on my desktop). I dont want to use the in-built workspace or Terminal(whatever is its name).
Can you guys please suggest what should i do so that i can login to the DB using the PUTTY only (i love it )? i am not able to login to the host "localhost" using the putty.
Few years back when i had installed vmware(linux installed in it and db installed on linux) i could connect through putty.
I am using below entry in the hosts file.
# localhost name resolution is handled within DNS itself.
    127.0.0.1       localhost
#    ::1             localhost
'localhost' and its ip address of 127.0.0.1 are non-routeable. Any request to send a network message to localhost will never leave the machine from which the request originates. And for all intents and purposes, your virtual machine is a different machine.

I AM PRESENTLY WORKING IN WINDOWS OS, DUE TO GOOD DEMAND IN AIX OPERATING SYSTEM AS BACKGROUND FOR ORACLE. I WANT TO LEARN, AIX BUT I DON'T KNOW FROM WHER CAN I GET THIS OPERATING SYSTEM. IF ANY ONE KNOWS PLS REPLY ME ON [email protected]

Well, first you need to buy the hardware, a pseries/system p box, and afaik the os is included.
As an alternative, maybe you can look into getting remote access to AIX host.
Also, please in the future do not use all caps in forum messages.

Need help configuring Oracle for admission control&analysis(diploma thesis)

Hi, board team!
I encountered your site by searching for professional Oracle-Boards.
The threads I found on this site are all very helpful and very professional!
Sorry, for my bad english. I will try to explain everything in a very detailed way, so that you will hopefully know what i mean.
But let me explain what's my problem.
I am a student and now I am writing my diploma thesis (Analysis of Capacity mechanism in Oracle) and I have to set up an Oracle 10g Database. I managed to install Oracle using the Universal Installer. In my opinion it's a very helpful tool!
But I have difficulties configuring the Database.
The Database has to determine comparable results. I generate 3 different types of users. Each user has its own characterisations (IO and CPU consumption). The consumption for each user is always the same! (When a certain user connects to a databse the transactions/queries will be always the same).
To determine this Resource-Consumption I programmed an infinite loop (written in PL/SQL) -> infinite and equal queries.
Unfortunately the results are not comparable. The longer the loop is running the more different the results are. The results are not significant.
I think this is because of the Redo-Log-Buffers, which grow with every Transaction. (I'm sorry for wrong estimates, but I'm just a newbie with Oracle and database-systems).
After that I tried to shut down the databse after EACH measurement and finally restart the database. Now the results were all about the same.
Are there any solutions to make it more efficient?
What would you do?
After the measurements, I will write them into a Table (for each user: IO- and CPU-Consumption).
If one of the three users connects to the databse again, there will be an analysis algorithm, which queries this table and collects the measured values and the actual system-utilization (V_$-table). Therefore i will write a small program in PL/SQL. The analysis-Function is a "Black-box". I just use the functionality and submit User-consumptions and system-utilization. The function returns a value (0 or 1; 0=deny, 1=allow).
I thought to implement my small-program with the Trigger-functionality or VPD. The PL/SQL-procedure will be called after a user logged on to the database. The significant values will be queried and submitted to the "black-box" (programmed in java). The submission to this "black-box" should by implemented with Java RMI or Java Beans.
Are there any better possibilities?
Thanks for your support!
Now i will install Windows 2003 Server and Oracle 10g r2

Configure Oracle for ODBC

Hi @ everybody,
i have an application, that needs a connection to my Oracle 11gR2 (11.2.0.3.0) Enterprise Edition Instance at a Red Hat 6 Server via ODBC. Is there any HowTo, where it is shown, how i configure that at ORacle side? Or is it enabled as standard?
You have to know: before the application was connected to a MySQL database, that has been migrated to the Oracle instance and now we want to setup the configuration.
Thanks and best regards,
David

Edited by: David_Pasternak on 02.04.2013 03:14By its very nature, ODBC sits between the application and the db-specific client software. It provides a generic interface for the application.

Windows Server 2008 R2 evaluation for learning purposes.

Hi to all,
what is the less expensive (and fully legal) way to build a private lab with Windows Server 2008 R2 virtual machines to practicing me to take exams for MCSA certification ? I have already terminated the 180-days evaluation period for Windows Server 2008
R2.
Many thanks

I've downloaded and installed several different versions of Windows Server many times using the same account and information, if there were a problem with it, I'm sure Microsoft would have raised a concern with me. You can't really run a business by
tearing down and rebuilding your infrastructure every 6 months, and by installing, using, and learning from evaluation installations, I am just one more able-bodied individual with Windows skills to improve the supportability of their current and future install
base. My use of those eval products has no real commercial value to Microsoft because I wouldn't pay for it if I had to and I am not using them within a business infrastructure.
Nothing in the evaluation terms of use that I have seen says you can only install it one time, ever, in any environment, and nothing in the delivery and use of the evaluation versions has prevented me from reinstalling.
The bottom line I guess is you have to use your best judgement. I wouldn't recommend continuously reinstalling to support a real business infrastructure as a way to bypass licensing. I can't tell you 100% beyond a shadow of a doubt that Microsoft
fully approves of reinstalling an eval for your own personal development needs. I seriously doubt that Microsoft would spend the time and resources to chase you down for it, though.
And I agree with Milos - you would be better off pursuing a server 2012 certification, for which there are also evaluation versions available.
I hope this post has helped!
