Oracle Express and regedit

Hi!
I installed Oracle Express on Windows XP and I want to use PL/SQL Developer (could be any other tool) to develop with pl/sql. But I realize that the Express installation does not creates the usual HOME0 or HOME1 nor ALL_HOMES Oracle entries in the regedit, and I need them so my tool can detect the instance.
Why the Oracle Express does not create these entries in regedit and how can I create them? I don't know which entries I need.
Regards

Hi,
Thank you for your fast response.
RPuttagunta, with the new PL/SQL Developer 7 trial it works fine and the database name XE is found, but with earlier versions like 5.0 (which is what we got in my project) it doesn't work. A workaround I found is to manually create the HOME1 and ALL_HOMES entries in the regedit, taking as a reference an Oracle 9i client installation. My question is if that regedit entries are present in the 10g and future versions, or we will have to patch all the installations.
Legatti, SQL Developer is fine and I liked, but PL/SQL Dev still has some additional features we are used to work with. Anyway I will suggest it to the manager as an alternative to get an upgrade of PL/SQL, since it is free to use.
Thanks & Regards

Deploying Oracle Express and Java Application in one installation

Is there a way to deploy a Java application using Oracle express as the back end in one installation? So in other words, rather than installing oracle express separately from the application, we are looking to install from one executable including both the java application and all the necessary components for oracle express to run.
Your help is greatly appreciated.
Thank you,
Mahmoud

Hello,
you can install the database using a response file. Depending on the installer of your Java application you could create a kind of meta-installer that creates a response file for the database as well as one response/parameter file for your application installer and hence run both in one step.
See the [url http://download.oracle.com/docs/cd/E17781_01/install.112/e18802/toc.htm#BABCCGCF]corresponding section of the Installation Guide for details on the response file.

Oracle Express and Displaying Better Error Output?

I recently installed Oracle Express 10g and I would like to make the DBMS app output better error codes (in this case, I guess the DBMS is "Application Express 2.1?"). Is there any way, for example, to output more precise error codes that will help me pinpoint where exactly a given problem arises?
A perfect example:
I just tried to run the following query against the database:
INSERT INTO ct_employee (ename, deptno, sal, mgr, job, hiredate, comm)
VALUES('Debbie Howe', 20, 30000, 122, 'Clerk', 17-Dec-80, '');
After clicking "Run", the following error message was displayed:
ORA-00984: column not allowed here
As you can see, there's no "arrows" pointing to where a given value might have been nosedived, nothing indicating where a column might be getting ignored or even anything explaining which value in general... Nothing. Only some obscure error code proceeded by Kafkaesque common sense (ironic).
So again, if anyone has an idea regarding how to somehow enable better error messages or the like, I would really appreciate it.

I wasn't using SQL*Plus...
What I was trying to do here out of all this was install Oracle to my actual computer so that I could start practicing SQL on my own without having to log into any development or production environments.
I installed SQL Express (completely free after registering to the Oracle website and logging into it with your provided e-mail address) for my main SQL / PL/SQL processing engine and after I did this, I then began using the "Application Express" to practice my SQL. Well, it turned out that it wasn't really doing what I needed it to (i.e. - various commands wouldn't output what I expected or multi-commands wouldn't work, etc.)
This made me eventually realize that what I had on my localhost, in terms of database, would suffice, but in terms of DBMS (in layman's, you're editor for SQL code, if you will) would not work. This led me to download SQL*Plus. The rest is history!
Steps to creating a basic localhost:
1.) Download Oracle Express (prepare for a big download). Install. If you get any error messages, chances are they're the same ones I had during installation. I never paid much heed to them and to this day, experience no problems. Just click through them...
2.) Download and install SQL*Plus. Again, expect a hefty download. The good thing about this, though, is that you only need to extract the main file and run the EXE in it. There's no installation involved.
3.) If you're using localhost for your database stuff, set everything up in your EXE first-run by entering the following:
Connection Name: "localhost"
Username: <username>
Password: <password>
(You can choose to save your password, too.)
I think everything else is already set, but in the event that it isn't, your hostname will be "localhost" and your port number will be "1521" (in most cases--this might be different in some office or work setting. In such an event, get with your systems geek.) Lastly, your SID will probably be "xe" and after you set all this up, you should press "Connect".
Then you're golden. :.)

Oracle Express and forms/reports

Hi there
If we install Oracle Express database on a remote site with single server can we run Oracle forms/reports on the same server that will connect to the Oracle Express database ?

Yes you can. Just create the required Oracle Net conntections and use it in your froms and reports. Ensure that the listener is running.

Inconsistence with oracle express and toad

I created two accounts(A and B) under system account under oracle express, then under system, A and B account, I created one table for each account (USER_TABLE) . I can see all three tables from oracle express. But I can't see the tables from toad. Even I can't see A andB schema from toad. Anyone knows what's the problem.
Thanks,
-- Allen --

I think I access to the correct db since there is only one db instance. Only system has the DBA privilege, A and B just regular account. The accounts I created from oracle express should reflect to toad, I can't see them, but I can see HR schema from toad.
Thanks,

Oracle express and jdbc

can i use oracle 10g express edition and jdbc connector to connect to it through java. i read on the comparison list that 10g express doesn't support java..what does it mean??

Thanks for your help.
I went through the features list comparing different versions of oracle ..express, standard etc from the following page :
http://www.oracle.com/database/product_editions.html
In the 'Application Development' section under, corresponding to 'Java Support' there is no tick mark....i guess i misunderstood the fine print which says :
"Grid-enable databases through Web Services"....
thanks anyway...

Oracle Express and Windows 2008 Server

I successfully installed the Oracle Database 10g Express Edition on our new Windows 2008 Server. However, after install I can not open the Database Home Page in IE 7.0? The problem description I get when I click on the Diagnose Connection is "127.0.0.1" is not set up to establish a connection on port "8080" on this computer.
The server is also a domain controller, DNS server and DHCP server.
Is this version compatible with Windows 2008 Server?
Is it a DNS problem or may be a security problem?
Heinrich

I have not tried it on Windows 2008. But the challenges with your configuration could be endless. Here are some common issues:
1) XE must be installed by a local machine administrator, not a domain administrator
2) XE requires several ports (1521, 8080)
3) Firewalls and antivirus are known to crash the install
4) Often 3) will block the installation of the database
Note that XE does not use any form of HTTP listener - the database listener does the bassic work and passes HTTP requests into the database. So no Apache or IIS requires with XE.

From MS Access One-to-Many Form to Oracle Express

Hello, hello,
Firstly, I am new at Oracle and interested to really getting into out, however, I am a little ancy to get going. I'm looking for some sharp direction that could direct me to exactly what I need to do right now and then I can do further study, etc.
I have a MS Access database with many tables, queries, etc. But I set up a fancy form whereby I could scroll to the name (let's say EMPLOYEE) and then I have about 10 different forms (a tabbed interface because there were so many) show up where I could input data about that employee specifically. Then when I scroll to the next person, all of the subforms would change accordingly.
Thus, ultimately, what I would like to do using Oracle Express and APEX is to set up a page where I have a region which will pull a list of employees and act as a menu, then when someone select an employee (i.e., not only me) then all information, from numerous different tables pulls up and is visible, editable and can be added to. There could be a region for addresses, a region for links, for notes, for photos, for a list of articles, or whatever.
I hope you track with what I am looking at. In Access I have numerous tables, then I create a monstrous one-many relationship thingamajiggy and ka-boom, things all fit together in a form, and subforms. All editable by me, but hardly available for anyone else. I know Oracle is the way to go, so...
Can you assist me by explaining what I need to implement in Oracle? I am not clear on JOINs and what's the right one to use, how to adequately connect all of the dots, etc. Do I need to set up fancy queries, create SQL statements or what?
Thanks.

Thanks. I don't think my question is strictly APEX related.
Rather, I am trying to determine how to create a "one-to-many" relationship (to use MS Access terminology) in Oracle Express. And then solve how to add data to them.
I can create a view which links two tables together where I can add data, but I want to be able to be adding data to several tables all linked together from the same primary key. One row per person (or employee) won't handle this, particularly if you want to add more than one row of data about the person in a table.
For example, if I had a restaurant with four employees (a cook, a waitress, a baker and a cleaner), my employees table would only have four rows. But now if I wanted to record the types of desserts the baker could make, that would take up more than one row. Therefore, from the baker, it would have to link to another table where I could input data about the different desserts. Typical one-to-many relationship. But the baker can also make different kinds of bread, thus another table with several rows. Perhaps the baker is so good, I may want to have yet another table for his different supremely delicious and famous pies (apple, pumpkin, pecan, etc.) which is now another table. The options are endless, but they all connect to the baker.
As a result, someone could come to my application and ask what can the baker do, and it will pull up a table of desserts, a table of pies and a table of breads.
Once I figure that out and can link many tables together using one primary key, then I presume I can easily move into the web application aspect. But for now, I am not quite there yet.
If someone can at least direct me as to what this is called in Oracle and give me a little direction, then I will feel more confident in moving forward. Thanks again!

Oracle Express. Right for us?

Hi All,
I am using Oracle 10g Express Edition. I explored Oracle Express and followed demonstartion/examples provided.
I am thinking of developing web-based small application involving following 2 modules as follows:
1) Timesheet for freelancers.
2) Invoice Processing.
My questions are as follows:
1) Is Oracle 10g Express Edition right choice for this?
2) I am now comfortable developing the application. But not sure how can I make this application accessible from outside.
Experts please let me help in this or send me some links which can help me.
Thanks in advance.

user7322857,
Firstly a name would be nice rather than user7322857 :-)
I have some experience very similar to what you are asking and can provide the following detail:
1. I have deployed Oracle XE onto a Windows 2003 Server box and it runs trouble free for a couple of years
2. The initial reason to use Apex was to build a Time Sheet application to replace a very clunky and non-scalable Access DB written system
3. We use the Apex user repository to provide authentication and user management although we are looking at integrating with AD
4. The Time Sheet app is used by over 200 users on a daily basis from several locations, including home workers using a VPN, the networking side of things was sorted out by our network admins
5. The success of this one app has led us to build a suite of other apps and we are converting a lot of Excel/Access based "systems" to Apex and getting a lot of excellent feedback from our business colleagues about our ability to deliver very useful apps very quickly.
So my personal opinion is that the combination of XE and Apex is probably right for you, and as Roel points out if your company cant host your DB there are plenty of hosting companies out there offering good value Apex hosting - or you could look at using Amazon EC2 http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1720&categoryID=205

How to install Oracle Spacial with Oracle Express Edition 10g?

Hello,
I'm new in Oracle Technology, I just wanted to try Oracle Spatial.
I don't know how to get it so I've installed Oracle Express and followed this tutorial :
http://oracledbas.blogspot.com/2009/06/manual-installation-of-spatial-10g.html
They say Jserver, Oracle interMedia and Oracle XML Database have to be installed, but only one of them seems to be set up (XML DB), I can't install the others.
If someone can help me to install Oracle Spatial, it would be nice. Bye.

If you want to use Oracle Express Edition, note that the 11.2 version is available on beta now:
http://www.oracle.com/technetwork/database/express-edition/overview/index.html
Its a while since I've used XE but from what I recall you get the Locator functionality, but not Spatial. That makes sense as XE is free, which Spatial needs to be licensed.
However, you can do an awful lot with Locator. To see if it is setup, just check if you have the MDSYS schema. Then describe the SDO_GEOMETRY type:
describe mdsys.sdo_geometry
If they are both there, then you're in business.

Oracle Express Edition And Windows Encrypted File System (EFS)

Hello,
I want to use oracle express edition with windows encrypted file system. I tried some possibilities like encrypting xe folder. But connection can not be established when efs is used. Is there a compatibility problem between oracle xe and windows efs? On Oracle's page, it is declared that oracle database is compatible with Windows EFS.
Thank you for help.

Pl identify which version of Win 7 - 32-bit or 64-bit ? Home version or something else ?
The 11g XE install is only available for 32-bit version of Win 7 Professional or higher - http://docs.oracle.com/cd/E17781_01/install.112/e18803/toc.htm#BABHICJH. If you are installing on 64-bit version or Home version of Windows, then you are on your own. What is the reason for enabling EFS on this database ?

Oracle Reports 6.x and Oracle Express Server

What are the benefits of using Oracle Reports in conjunction with Oracle Express Server? We are currently using OFA for planning and forecasting, and are evaluating Oracle Reports as a tool to produce and publish key financial reports for a large user community. Is there any benefit in using Oracle Reports rather than just creating and publishing the reports directly within OFA?
Thanks,
Bill

Bill,
we tried to use Reports 6i with Express server. There were many troubles.
1. It is very hard task to establish connection Reports/Express
2. It is not possible to enter parameters for the reports
3.There are limitation on the number of dimensions in the report
