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...

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 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

Oracle Express and Forms

Hi
Does anyone know if u am able to user oracle forms fromt eh development suite to connect to a oracle express xe edition?
or do i need to download the full version of the DB.

Forms can be used with Oracle 10g XE or 11g XE....: http://oraclekit.wordpress.com/2011/02/02/connecting-oracle-forms-6i-to-oracle-xe-10g/

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.

Able to make dirty read using Oracle 9i and JDBC thin driver v 9.2.0

I've searched this forum and did not see anything to directly answer my question.
I checked the Oracle JDBC Frequently Asked Questions...
ditto (perhaps due to the fact that it was last updated: 22 June 2001).
So here is my question, and thank you in advance for any insight (apologies if I have missed finding an already answered question):
Section 19-15 of:
"JDBC Developerâs Guide and Reference"
(which is for Oracle 9i database)
downloadable from:
http://download-east.oracle.com/docs/cd/B10501_01/java.920/a96654.pdf
is entitled:
"Transaction Isolation Levels and Access Modes"
The section seems to indicate that
if JDBC connection A is setup with:
setAutoCommit(false)
setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED)
and then used to perform an update on a row (no commit(), rollback(), or close() yet) ...
then JDBC connection B (setup in the same way) will be prevented from
making a dirty read of that same row.
While this behavior (row-level locking) occurs correctly when using MS SQL Server 2000,
it is not occuring correctly with Oracle 9i and the Oracle Thin JDBC driver version 9.2.0.
The test case I have shows that with Oracle, connection B is able to make a dirty read
successfully in this case.
Am I doing something wrong here ?
Again, MS SQL Server correctly blocks connection B from making the Read until Connection A
has been either committed, rolled back, or closed, at which time connection B is able to
complete the read because the row is now unlocked.
Is there a switch I must throw here ?
Again, any help is greatly appreciated.

Thanks for the response.
I understand what you are saying...
that readers don't block writers in Oracle (the same is true in SQL Server 2000).
However, I don't see how my test case is working correctly with Oracle (the exact same code acting as I'm thinking it should with SQL Server, but I still think it is acting incorrectly with Oracle).
I have transaction A do this:
update <table> set <column2>=<value> where <column1>='1'
then I use Thread.sleep() to make that program hang around for a few minutes.
Meanwhile I sneak off and start another program which begins transaction B. I have transaction B do this:
select * from <table> where <column1>='1'
and the read works immediately (no blocking... just as you have said) however, transaction A is still sleeping, it has not called commit() or rollback() yet.
So what if transaction A were to call rollback(), the value read by transaction B would be incorrect wouldn't it ?
Both A and B use setAutoCommit(false) to start their transactions, and then call setTransactionIsolation(Connection.TRANSACTION_READ_COMMITTED).
Isn't that supposed to guarantee that a reader can only read what is committed ?
And if a row is in "flux"... in the process of having one or more values changed, then the database cannot say what the value will be ?
I can almost see what you are saying.
In letting the reader have what it wants without making it wait, I suppose it could be said that Oracle is holding true to the "only let committed data be read"
So if that's it, then what if I want the blocking ?
I want an entire row to be locked until whoever it in the middle of updating, adding, or removing it has finished.
Do you know if that can be done with Oracle ? And how ?
Thanks again for helping me.

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 CEP and JDBC Adapter

I am using Oracle CEP 10g on WIndows.
I wrote the following code on CEP:
OracleDataSource ods = new OracleDataSource();
ods.setURL("jdbc:oracle:thin:scott/[email protected]:1521/orcl");
Connection conn = ods.getConnection();
// Check for the existence of a previous customerID
String selectStmt     = "SELECT * from STEPS " +
     "WHERE (streamID='" +
     this.customerId +
     "') and (assetid='" +
     this.eventName +
Statement stmt = conn.createStatement();
//System.out.println("-- calling SELECT");
//System.out.println(selectStmt);
ResultSet rs    = stmt.executeQuery(selectStmt);This works great, except it is exceedingling slow. I am sending about 20,000 messages to this code.
I think the problem is that I open the connection everytime I perform a select (and later an insert statement).
The server instance goes away after the message has been processed, and I can not save the connection.
Would using an adapter in config.xml prevent this openig a new connection every time a message invokes this code ?
If so, I have never done JDBC with an adapter and I dont understand how to use an adapter to use a WHERE clause to select on variables, since in the example I have seen so far, it places "SELECT 1 from DUAL" into the config.xml and does not explain how to get mix have the SELECT statement interact with code variables or better yet how to get your code to get a connection handle.
Could someone please post an exaqmple of how to use an adapter with JDBC, and possibly how to get your code to access a connection handle from the config.xml ?
Thanks

Hi,
From note : 831162,
<i>Oracle JDBC Driver (classes12.zip / classes12.jar) Deadlocks
Q: I have deployed the Oracle classes12.zip / classes12.jar JDBC driver as per the instructions in the XI Configuration Guide.
Unfortunately, I frequently notice hanging database connections. A thread dump taken according to the instructions in note 710154 shows one or more blocking JDBC Sender/Reciver threads and optionally that the JVM has detected a deadlock.
A: <b>The Oracle classes12.zip / classes12.jar driver is compatible with JDK 1.2 and 1.3 only, but not with JDK 1.4. Upgrade to a current version of the driver (ojdbc14.jar). For details, refer to note 941317.</b>
Make sure that you remove classes12.zip / classes12.jar from aii_af_jmsproviderlib.sda prior to adding the new driver as per the instructions in the answer to question #1 above as you will get a class name collision otherwise (all JARs from aii_af_jmsproviderlib.sda are loaded into the same class loader and the driver class name of both driver versions is the same).

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
cheers,

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.
