How to create a database for sample code from Tutorial/Book?

I want to try out the sample code from [http://shop.oreilly.com/product/0636920013471.do] for the book SQL Pocket Guide 3rd Ed.
I have downloaded the oracle vm/appliance for oracle 11g2 and I have started sqlplus as sysdba.
I'm feeling overwhelmed with these links describing how to create a database:
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
[http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html]
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
(1) What is the command to list the existing databases?
(2) What is the command to delete an existing database?
(3) When creating a new database with the create database command, is it necessary to specify the logfile, character set, national character set, datafile, sysaux datafile, undo tablespace, temp table space? Do these have reasonable defaults? I'm not sure what proper directories are to specify for Linux and the examples are for windows.
Can someone give me a simplified create database command to create a database called 3rdEdPocketGuide? Should I follow the example at [http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html] and instead of orcl use 3rdEdPocketGuide?
(4) What command do I use to execute the script that comes with the book SQL Pocket Guide 3rd Ed? This is the script that has all the drop table, create table and insert commands in it.
(5) What command do I use in sqlplus to set the current default database prior to running this script? Perhaps this is the connect command? I don't want my script to create tables in the system database.
(6) I tried the command "connect 3rdEdPocketGuide" and it prompted for a password! Yikes! What password? Do I need to specify a password when I create a database? I cannot tell if I have successfully created such a database or it is just prompting me for a password to thwart malicious users. Is it is possible to create databases which don't require a password or maybe a zero length password?
Thanks
Siegfried

Paul,
Thanks! I tried changing my profile name to siegfried but I'm not seeing the change...
Anyway, I'm trying your suggestion to use SQL Developer which was already installed in the virtual box appliance and I cannot figure out how to get a connection.
When I use the defaults of sid=xe, port=1521, hostname=localhost and specify
username=sysdba
password=
I get status: failure - test failed: listener refursed connection with the following error: ORA 12505, TNS: listener does not current know of sid given.
So I try sid=orcl and that works better: status: failure - test failed: ORA-01017: invalid username/passowrd; login denied
OK, sqlplus let me in with out a password, why does not this work?
So I try checking the box for "OS Authentication" and I get the same error!
Hoek: I tried searching the documentation and found "3 Exploring Oracle Database with SQL Developer" at http://docs.oracle.com/cd/E11882_01/appdev.112/e10766/toc.htm but following those directions did not help. Can you be more specific? The directions were for a tutorial and I need to know what the passwords are for the database set up with [http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html|http://www.oracle.com/technetwork/database/enterprise-edition/databaseappdev-vm-161299.html] . I also found [http://docs.oracle.com/cd/E11882_01/appdev.112/e10766/tdddg_connecting.htm#CEGHFHIG|http://docs.oracle.com/cd/E11882_01/appdev.112/e10766/tdddg_connecting.htm#CEGHFHIG] but that did not help either.
Everyone:
Do I need to create a user using SQL*Plus first so I can login with "Oracle SQL Developer" so I create my database called? What would be the "create user" command I would execute?
OK, so I run sqlplus and issue these commands
create user siegfried identified by abc ;
grant connect to siegfried ;
connect siegfried/abc;
Now, how do I create a database? In Microsoft SQL Server one has to create a database first and if you just start creating tables without creating a database first, the tables will be created in the system database and this is usually undesirable.
Sometimes a database is known in the java connection string as the catalog. Is there any such analog in oracle SQL plus?
So now what do I do? I want to create a bunch of tables using my script I downloaded from 3rd Ed SQL Pocket Guide. Does my new user "siegfried" have the right to create tables? I guess I could try but I don't want to create tables in the system database.
I noticed I can also use "Oracle SQL Developer" to connect with my new "siegfried" account. It seems that I should have been able to connect with sysdba... strange.
So now I am connected in the "Oracle SQL Developer" and I see no list of databases.
Thanks!

  • How to create Transaction Variant for T code F-30

    Hi
    I want to create a Transaction variant for T code F-30, so that user can't change the currency field and put any value in rate. Currency should be always in USD.
    Any input will be heighly appriciated.
    Regards
    Shiv

    Hi,
    In that case you can use transaction SHD0 to create a transaction variant for F-30 with its screen variant for screen# 122. And you also want to creat a so called Variant Transaction Z-something for F-30 using the mentioned transaction variant. You restrict users to use that Z-something. For other unrestricted process, the system will still cal F-30. Here is the documentation:

  • How to create a material for company code ??

    hii

    If not , explain me the reason ??
    Only plant wise is possible in standard SAP??
    Thanks

    Basic data 1 and Basic data 2 views-----General data --Client level data
    Purchasing , MRP Veiws and ---Plant level data
    General plant/Stor 1 and Stor 2---Storage location level.
    SO you are having the only one company code then, you can say Client level data is company code data.

  • How to create a database for keeping track or similar topics

    I have been using Macs for years. Only to do what I needed. Not a geek. In Appleworks years ago I could create a data base where I could organize categories i.e. I am a yoga teacher and could list the various poses that were good for headaches. Some of these were also good for something else. With the data base I could parse through for what I was looking for. I want to do that again and cannot figure out how to do it.
    Help appreciated.

    You could probably use something like [Bento|http://www.filemaker.com/products/bento/features.html] for the job, or even do something basic with a Spreadsheet in Numbers or Excel.

  • How to create business operation for starting workflows

    How to create business operation for starting workflows from worklist?
    When I call methods that implements business operation from java class everything
    works fine(wlpi-ejb.jar is required), but when I call business operation from
    Studio I can't use classes from wlpi-ejb.jar.

    Business operation is called by WLIS. So, I include wlpi-ejb.jar into WLIS classpath.
    Studio uses deployed EJB from wlpi-*.jar, I don't know why Studio doesn't see
    methods from deployed EJBs when WLIS classpath contains wlpi-ejb.jar.

  • How to create a object for IPageItemControlData?

    how to create a object for IPageItemControlData?

    From the header comment you'll see that IPageItemControlData is an Interface of PageItemWidget. That must've been an InDesign 1.0 or 1.5 feature predating kPageItemBoss, because except for the same comment even in InDesign 2.0 SDK the only further reference is a copy in the comment of its sibbling IFrameControlData which was removed with InDesign CS.
    The IID and kPageItemControlDataImpl are probably only around because deep under the hood there must be some kind of conversion provider waiting to do its job on a very old document.
    I guess the closest in today's functionality will be IHierarchy.

  • Looking for sample code to create my own pub/sub!

    I am a new bee in JMS. So I would really appreciate if
    some one could give me some hint to start up with my school project. I am looking for a sample Java code that will:
    For the Publisher:
    1. Connect to a broker [create it, if it does not exist]
    2. Create a publisher/destination.
    3. Create a pub-sub queue
    4. Publish a message
    5. Ack or Nak depending on if the subscriber got or did not get the message.
    For the Subscriber:
    1. Connect to a broker [create it, if it does not exist]
    2. Subscribe to the broker
    3. Subscribe to the Queue
    4. Show an received messages on the console.
    Here are the command line params for both the Publisher and subscriber:
    runPub 127.0.0.1:7676 myTestBroker myQueue "this is my message"
    runSub 127.0.0.1:7676 myTestBroker myQueue
    Please tell me if there are similar java code that will do all this and work with ANY JMS compatible client. i.e. I should not have to use the Admin tool of any JMS Server (MQSeries, iPlanet, SonicMQ etc etc). The code should follow the JMS spec and do this programmatically.
    Thank you very very much in advance for doing this great favor.
    With regards,
    Amir.

    Thanks a lot for that hint. I think that's a great tutorial for a beginner. I could compile those sample codes from chapter 4 with out any problem, but could not run it. I also installed j2sdkee1.3.1 and updated my classpath according to the spec. But when I tried to run the "j2ee -verbose" command it was giving me the following error message:
    ERROR: Set J2EE_HOME before running this script.
    Any advise for me that I should follow next. Thanks again.

  • How to create Activex object for my Visual C++ object

    Hi,
    I am working on development on Acrobat 9.0 SDK. I am facing problem is that I can compiled Visual C++ source code to an api. I can test functions on this api on Acrobat 9.0 windows, but I could not test it on IE web browser, because I don't know how to create Activex object from my Visual C++ source code or its api.
    I read Acrobat 9 SDK document and found under C:\Acrobat 9 SDK\Version 1\PluginSupport\Tools\Visual Studio App Wizard has two files: Acro9PIWizInstaller.msi and setup.exe. I am not very sure those file are the key to help me to create Activex objects for my api.  Are they the one I need to create Activex object? If not, could you please advise me how to create Activex object for my api or C++ codes.
    Thanks a lot for any of your comments or advices.

    Hi lrosenth,
    Thanks a lot for your information.
    My question is, on Javascript how do I call a function from .api. Below is my very simple test.
    I got a function on BasicPlugin.cpp under C:\Acrobat 9 SDK\Version 1\PluginSupport\Samples\BasicPlugin. See below.
    I added BasicPlugin.api on C:\Program Files\Adobe\Acrobat 9.0\Acrobat\plug_ins
         ACCB1 int ACCB2 MyPluginCommand() {
              int num = 5;
              return num;
    On my HTML file, I create an <Object> below:
        <OBJECT id="acrobatapp"
                classid="clsid:85DE1C45-2C66-101B-B02E-04021C009402">
        </OBJECT>
        <OBJECT id="acrobatpdf"
                classid="clsid:CA8A9780-280D-11CF-A24D-444553540000"   >
            <Param name="SRC" value="http://www.adobe.com/devnet/acrobat/pdfs/acrobat_digital_signature_appearances_v9.pdf">
       </OBJECT>
    On my Javascript. I call function MyPluginCommand() as below, but it is not working. How do I call function MyPluginCommand() on Javascript?
         var acrobatapp= document.getElementById("acrobatapp");
         var num= acrobatapp.MyPluginCommand();
         alert(num);
    Thanks for your support,

  • How to create first database

    Hi there,
    This is my first post on this forum. I am totaly new to Oracle as I am working on one project which require Oracle as db.
    I have installed Oracle Database 10g Express Edition. I can login by system user or as hr. Now when I am trying to create database instance for my project.net application, I am not finding the option to create the db. Its manual (even here in forum someone) pointed about Configuration and Migration Tool menu under Start/Oracle. But I don't have that option under my oracle. What I have is Start > Oracle Database 10g Express Edition > 1) Help 2) Backup Database 3) Get Started 4) Go to Homepage 5) Start SQL command line 6) Start Db etc...
    Can anyone guide me how to create first database? Thanks in adv and your answer will really be appreciated.
    Regards,
    Yatrik

    I think I didn't explain properly. I can connect. I have got two database users as well. The one is default hr and second I just created as yatrik.
    By saying how to create database, I want to accomplish this below procedure.
    Run the Oracle Database Configuration Assistant located in the Windows Start/Oracle/Configuration and Migration Tools menu to create a database instance for the Project.net application. 1. Select Create a Database the click Next.
    2. Choose the General Purpose database template.
    3. Note the Global Database Name and SID that you use.
    4. Choose your preferred management method. If unsure, chose the default.
    5. Note the password(s) you use for the various accounts.
    6. Select the appropriate storage mechanism for your installation. Again, if unsure, chose the default.
    7. Specify the storage location.
    8. And Recovery Configuration.
    9. Do not install the Sample Schemas.
    10. Select the remaining options, as appropriate to your installation, and create the database. Here when I go to Start > Oracle Database 10g Express Edition, I don't get Configuration and Migration Tools Menu anywhere. The above steps says how to create it but I can't find that tool menu.
    I know how to create tables and all such but I am looking for that particular option where I can complete the above steps.
    I hope I have explained more briefly to understand what I am trying to do.

  • Looking for sample code using "first_tab" and "next_tab"

    Looking for sample code using "first_tab" and "next_tab". How is it used with ItemID within a dialog box? I've read the reference books - don't understand it.

    Hi Ray,
    There are several ways to do this, and in the example I created, I actually did not end up using shift registers. I've attached some example code that basically multiplies the period by the duty cycle percentage to achieve the number of milliseconds to be high and low.
    You would just need to insert your DIO code in each frame of the sequence structure.
    Hope that helps. Kind regards,
