Failure to connect JDeveloper 10g to Oracle Database Expres Edition.

Hi, i working with Oracle JDeveloper 10.1.3 and Oracle Database 10g Express Edition. CONNECT to Oracle Database XE from Jdeveloper Wizards using JDBC/Thin, generate the next error messge:
ORA-0064: error ocurred at recursive SQL level 1.
ORA-12705:Cannot access NLS datafile or invalid environmment specified.
Vendor code: 604.
, but connect to using ODBC work Ok.
If run the application display:
17002:Exception of E/S: SO: Exception was generated.
Roberto.

Hi Roberto,
this issue can be caused by language incompatibility between JDeveloper language (client language) and database language.
To check the language of the database, execute the following SQL statement from the DB:
select * from nls_database_parameters;To check the JDeveloper language:
Select menu Help --> About in JDev, and see the values for:
user.language, user.region.
Are they the same ?
If not,
1. Edit <JDev_Home>/jdev/bin/jdev.conf file.
2. Add the following parameters:
AddVMOption -Duser.language=...
AddVMOption -Duser.region=...
with the values for language and region, f.ex. en and US respectively
3. Restart JDeveloper and re-test the connection.
Hope this helps,
Didier.

Connecting form 6i to oracle database 10G express edition

I am unable to connect forms 6i to oracle database 10G express edition.
form builder closes without any message.

Hi, i was try that solution, but have some problem.
1) I have stopped other database (Oracle 8i, OracleService + Listener), none Oracle service was running.
2) I was install Oracle XE Univ.
3) Run sqlplus from XE
"D:\oraclexe\app\oracle\product\10.2.0\server\BIN>sqlplus system/PASSWORD@xe as sysdba"
4) Shutdown immediate - OK
5) Startup mount - failed
SQL> startup mount
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
6) I was check registry "hkey_local_machine\software\oracle" and delete key "local" (walue was set to connection to 8i database).
7) I was checking status of Listener from XE (after shutdown).
"Listening Endpoints Summary...

Have anyone suggestion how to connect "directly" to XE (without @CONNECTION string) ?
If source of problem can be having DB 8i installed on same machine ?
BBye.

Oracle Database Express Edition 10g Download Issue

Hi everyone. I just downloaded the freeware Oracle Database Express Edition without any apparent problems. However, when I attempt to go to the Express Edition Homepage, which is location http://127.0.0.1:8080/apex,
I get the message that my Internet Explorer cannot display the webpage. (It can, however, display other pages.) I cannot understand why this is the case since I successfully added Web site 127.0.0.1 in my Control Panel (as specified in the instructions.) Also, the instructions stated that HTTP port 8080 was the default port, unless my system said that this was not available (which it did not.) I also tried rebooting, which did not make a difference. Help!
Thanks,
Jason

Also, the instructions stated that HTTP port 8080 was the default port, unless my system said that this was not available (which it did not.) I also tried rebooting, which did not make a difference. Help!There is a forum dedicated to Express Edition, in which we have discussed a lot of the variants in failure that causes this problem. At the top of the page you are reading, there should be links like "Forum Home » Database » Database - General". The middle one will get you to a list of all Oracle forums and after the first 5, the rest are alphabetical - XE is pretty far down that page.
(You might also note that there is an Installation forum next to this one. That might be better suited to the task than the 'catch-all' general forum.)
The most common issues are related to not preparing the operating system properly. For example, if you use a laptop you probably use DHCP to get a different address from the various sites you connect to. However, Oracle works as a server and depends on having a well known address. In fact, it tends to bind the IP address at install into it's configuration files. Therefore it is critical to use the loopback adapter in such situations.
Other issues are dependent on the actual OS into which you install. For example, Ubuntu (Linux) has very differnet install philosophy as Red Hat / Fedora, and requires a different install technique. Then again, on Windows, it is nearly impossible to install anything Oracle on a Windows 'Home' OS, and XE generally has not even been tested against Windows 7.
Other common reasons include anti-virus; firewall; not having appropriate operating system level permissions; in Windows - using a Domain-based userid instead of a local administrator; and just general finger issues.
Express is considerably different in the install behaviour and runtime behaviour. For example. it uses RPM and MSI instead of Oracle Universal Installer. It does not include Java in the database, which limits a lot of functionality. And it uses the built-in PL/SQL Web Gateway instead of any external HTTP server. As a result, it can be quite a shock to mmany of the regular inhabitants in this forum.
I strongly encourage reading the documentation for XE. In particular, reading the install doc. Start at http://tahiti.oracle.com and look for the Oracle Database 10g Release 2 Express Edition documentation. (Just below the Oracle Database 10g Release 2 documentation.)

Connect Problems with Oracle Database Express Edition 11g Release 2

Hello,
I am a student trying to install Oracle Database Express Edition 11g Release 2 and SQL Developer on my home system, Win7 64Bit, in order to practice some things I've learned from me DBA class and Developer classes.
Anyway, I have everything installed, but I am having difficulty connecting as SYS or SYSDBA in the 'Run SQL Command Line', I keep getting the ORA-01017: invalid username/password: logon denied.
However, If i select the 'Start Database' I get this:
C:\oraclexe\app\oracle\product\11.2.0\server\bin>
and I can type sqlplus / as sysdba and it starts up just fine and show user lists me as "SYS".
but if I go back to 'Run SQL Command Line' I still cannot connect as SYS or SYSDBA...I find this both confusing and frustrating. I don't know if I am in different instances or something like that, but I seem to be limited to connecting only as "SYSTEM". I need SYS because I want to practice creating datafiles, instances and things like that, but I seem to be lost.
Also, I am trying to create a new DB connection with SQL Developer and I can only us SYSTEM for my login which, if I understand correctly, will limit my privileges. Again When I try to sign in with SYS or SYSDBA I get error'd out. When I installed Ora11gDBExpress I was prompted in input a single password that was supposed to grant me access as SYS or SYSTEM, but I am limited to only SYSTEM for some reason.
So, I am looking for help/guidance as to what to do.
Thanks in advance for any and all help,
Warren

General rule of thumb, don't use sysdba unless you want to shut down the database, or grant a database user privileges on a sys object.
A SYSTEM connection is not "limiting", it has the DBA role which means a user with a system connection can do most anything needed, including select/update/delete/drop any user's objects as well as change parameters in the instance.
The system user can indeed add datafiles, tablespaces, etc. The instance and database should already be created as long as the installer completed all its chores correctly. For XE, per the license agreement only one instance can run on one host. If you want to try creating a database, it will require shutting down the XE instance and creating a new database service, creating the database, and installing the system catalog and any other optional components desired. Good practice indeed, but a bit advanced for the new user.
Do create users for schemas ... connect system; create user <username> identified by <password> and connect <username> for the schemas (a collection of objects) within the database. Grant the resource and create session privilege to <username> to allow the database user the ability to create tables, indexes, stored procedures, etc.
There is no "or" in a sys as sysdba connection, from 10g onwards a sys connection requires using the sysdba privilege. To enable a sysdba connection, add your host user to the ORA_DBA group on the host. To verify the OS users in the ORA_DBA group, this might work for win7, in a cmd box ...
$ net localgroup ora_dba
...If your OS user is in the ora_dba group the sys as sysdba password is not relevant, you can in fact type anything for a password. If you wish to connect with the sysdba privilege from a remote client, that is a bit different and requires knowing the password set in the instance password file. Which should be set the same as the system password defined in the installer, but you can change that by creating a new password file. Another slightly advanced topic.
In Windows IMHO its better to leave the listener and database set to Manual start (in the services applet, Start/Run/services.msc) and start the listener, then the database, when its needed. At least for an XE instance, as its intended for practice and learning RDBMS management.

Oracle Database Express Edition 10g; Designer, PL/SQL; Download

Hi,
I am new to this forum, I hope that I am posting in the right one :)
I am refreshing my SQL knowledge an installed the "Oracle Database Express Edition 10g Release 2 (10.2)" which works fine. I now would like to learn PL/SQL and Oracle Designer.
Are these 2 also offered as a free download for personal use? Since the Oracle website is pretty complex I am not sure what I should download.
Can I run these programs on one WinXP Home machine?
Thanks for your help!

Designer is not free like Express Edition. You cannot use it for any commericial purpose without a licence.
Designer is a big tool. I don't know why it shouldn't run against XE but it is a tough blighter to configure and install. It is also a moribund product, so the answer to this question:
Is there a newer Designer version available?is likely to be "No" whenever you ask it.
Cheers, APC

Connecting to a non-oracle database (jdbc) from a java stored procedure

Does anyone know to configure the database to allow a connection to a non-oracle database from a Java Stored procedured, using JDBC?
Thank you in advance,
Chris

Hi Chris,
I haven't tried it, and these are just some of my thoughts, but I
think you would need to load the JDBC driver for the other database
into the Oracle database (using the "loadjava" tool, of-course).
Then your java stored procedure should be able to instantiate the
third party JDBC driver and obtain a connection to the other database.
Hope this helps.
Good Luck,
Avi.

Oracle Database Express Edition 2 Day Plus Java Developer Guide??

I posted in the JDeveloper forum, as well as sending email via your feedback link found on the tutorial but I am a little disappointed by this:
The Oracle® Database Express Edition 2 Day Plus Java Developer Guide has some errors in it.
in Windows, I simply chose, start
-> programs -> Oracle Database Express Edition -> Go To Database Home Page -> click documentation from the link -> and run the Oracle® Database Express Edition 2 Day Plus Java Developer Guide tutorial.
the problem is there are mistake(s) in the tutorial, for example: section 4-19 is this:
"The complete code for the method should now be as follows:
public boolean authenticateUser(String userid, String password,
HttpSession session) throws SQLException { "
it needs to be this:
public boolean authenticateUser(String jdbcURL, String userid, String password,
HttpSession session) throws SQLException {
Also:
there is no mention that :
the port and SID must also be passed in the
ds.setURL(jdbcUrl) found in the authenticateUser() method, or an exception is thrown. This differs from value of the jdbcUrl string found in the getDBConnection() , which makes it hard to figure out
The tutorial is great even if it doesn't work out of the box, but I am disappointed that errata or completed code for this project is not available, especially when you explicitely point to it via the steps mentioned above.
Thanks,
Patrick

The tutorial seems to be using the old JDeveloper 10.1.2.
If you are aiming to learn JDeveloper then just use the tutorials linked from the JDeveloper home page.

Oracle Database Express Edition SQL Developer

Hi all,
I did download the Oracle Database Express Edition from Oracle's website and am trying to create a new connection with the following info
Connection Name: myconnection
Username: ora21
Password: ora21
Hostname: localhost
Port: 1521
SID: orcl
Note: I even tried to use xe as the SID since it's a express edition but it keeps telling me test failed: ORA-01017: invalid/password; logon denied.
Could it be because it's an Express edition? Please advice as am a new DBA and am practising on my own

@Jim: thanks for the reply! I just created the user ora21 but when I try to creat the connection again it gives error ORA 01045 : user ORA21 lacks create session privilege; logon denied.

Oracle Database Standard Edition One's Cost

Dear all
I am very interest on the Oracle Database Standard Edition One, (US$149 per user (minimum five users)) includes the functionality and the cost (only US$ 149*5). However, I would like to know that is there any hidden cost for it? (e.g. maintaince fee etc.) Meanwhile, is there any backward compatible for the such license (i.e. I buy 10g version but use 8/8i version in production)
Anyone can has such experience and share for it?
Thanks in advance
Regards

There is generally a lot of confusion around Standard Editoin One. Here is my understanding, along with rationale and links supporting my understanding.
1) Standard Edition One was NOT part of Oracle8i, and NOT part of Oracle9i release 1.
Oracle's "Oracle9i Family of products" document, released shortly after 9iR1, does not mention SE1. http://www.oracle.com/technology/products/oracle9i/pdf/o9i_family_features.pdf
2) Standard Edition One MAY be part of Oracle9i Release 2 family, but it's not likely.
On metalink, there are a few 'forum' documents that discuss SE1 and Oracle9i. However, document #530049.994 from forum thread "Is Standard Edition One available in 9i/9ir2", dated 05-OCT-2004 says SE1 is a 10g new thing. (This post should be available in these forums.)
3) No-one purchasing a new license should be installing a fresh copy of Oracle8i and probably not Oracle9i
You purchase the license primarily to obtain (be able to purchase) support. Oracle8i is no longer under support (except through an exorbitantly priced extended support contract) and Oracle9i is abount to be mved to extended support. The question is ... why?
4) Personal Edition is NOT being replaced by SE1.
The Standard Edition One is a subset of Standard Edition - mainly missing RAC, so it is limited to one machine only. From the Oracle Database 10g Licensing document we note that the Personal Edition provides ALL FEATURES AND OPTIONS of the Enterprise Edition, except RAC.
It is fairly obvious from this that Personal Edition is targetted at developers who need metalink access, whereas Standard Edition One is targetted at workgroups that would consider using SQL Server STabdard/Workgroup Edition.
