Oracle 10g express: trouble with control file

Hallo,
I have just installed Oracle 10g for Linux; my distro is Fedora core 4. After configuring the environment variables, I try to startup the XE database by invoking sqlplus as oraclexe user. The command fails with this error message:
ORA-00205: error in identifying control file, check alert log for more info
The alert log says that the control file control.dbf is missing, and actually it is, along with every data file and log.
Could anyone give me one hint?
Thanks
Franco Pingiori

Oracle 10g express Edition Database

We are using oracle 10g express edition with a temporary storage space for a class using SQL. When creating and using the database, the data is being deleted after 1 or 2 days and students are having to start over, creating tables and inserting data. Any suggestions?

suggestions?Backups?
Or, as long as the DDLs and DMLs don't take long, rerunning table create and insert SQLs would probably be much faster than setting up the database(s) in archivelog mode and copying datafile/archivelog files or rman backup files someplace that won't get reimaged every other day.

Connecting oracle 10g express edition to jdeveloper

I am having all kinds of problems connecting oracle 10g express edition with my jdeveloper 10.1.3.3. I can query the database from my command line so I know it is set up, but for whatever reason jdeveloper will not connect with it. When I try to connect with the database through jdeveloper here is the error I keep getting:
Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
localhost:1521:ORCL
I have been all through the google results looking for an answer and have come to the conclusion that it is something with either the listerner file or the tns file, but as of yet have been unable to locate them. here are both of those files too.

Please any help would be appreciated I have been at this for days, thanks.

This has to be some kind of bug with 10g express because I see lots of people having similar problems. I'm in the process of uninstalling 10g, and I will re-install it see if that makes a difference. Again if anyone has any other ideas please keep them coming because this is utter BS it shouldn't be this hard.

Number of available records in Oracle 10g express database

Hi,
I am facing problems in getting the number of available records in Oracle 10g express database with the following query.
string filename = dbObject.FILENAME;
string vendorID = dbObject.VENDOR_ID;
OracleCommand myCommand = _connection.CreateCommand();
myCommand.CommandText = "SELECT COUNT(*) FROM ASSET_PROCESSING_OUTPUT WHERE *FILENAME = :filename AND VENDOR_ID = :vendorID*";
myCommand.CommandType = CommandType.Text;
myCommand.Parameters.AddWithValue("filename", filename);
myCommand.Parameters.AddWithValue("vendorID", vendorID);
OracleDataReader reader = myCommand.ExecuteReader();
Using this command how can I get if the record exists in the database with the given value.
Thanks in advance.

It appears you're only executing the statement. You need to fetch the result to see the value returned by the SELECT statement.

I have a problem with oracle 10g express edition

Hello,
I have just installed oracle 10g express edition and I have a problem with the script editor. I can write anything in the window that appears below buttons undo,redo and find, It is like disabled. I use windows XP, Firefox 2.0 ( I have also tried with Iexplorer and It does not work either). I have javascript enabled.
anyone knows what is the problem?
Later,I have installed it in a virtual machine of Windows 2003 Server and It works well but I`d rather use it in my Microsoft XP
Thank you very much
Fernando Martínez

It looks like you can fix this if you replace the codearea.xbl.xml and codearea.iframe.html files in the
/i/editor folder with files from an Apex 2.2.1 installation - such as the one on apex.oracle.com.
Since I don't know what the licensing implications are, I will let you figure out the details.

Java Connection Pooling issue with Oracle 10g Express Edition

Hello
I have a Java based web application that uses the Oracle 10g Express Edition database. I am using a connection pool to get connections to the database.
I use the NetBeans IDE and run my web application on the bundled Tomcat server(5.5.7) that comes with the IDE. Though when I initially run the application from the IDE, the connection pool is set up fine, when I recompile my java code and try to run the application again, I get the following error each time:
Listener refused the connection with the following error:
ORA-12516, TNS:listener could not find available handler with the
matching protocol stack.
The logs before the error shows up, indicate that the connection pool object is fine and gives me the number of available connections and the number of active connections and so on, which I have printed from the constructor of the Connection Pool class:
For e.g.:
Cache size = 17
Available Connections = 17
Cache Limit = 1000
Active size = 0
However, if I kill my Tomcat server process and run the application again, it works fine with no error.
I looked around for possible causes and solutions and all I could find
was increasing the processes parameter value in the init.ora file. I have increased the parameter value to from 100 to 20000 now, in increments of 500/1000 each time but it hasnt worked so far.
Someone else suggested that I increase the size of my connection pool; I initially had it set to a minimum limit of 5, an initial limit of 10 and a maximum limit of 1000. However if I set the Initial Limit to anything above 17 connections, I see the following log on the Bundled Tomcat log and my application doesn't run at all:
Log: Loading JDBC Driver : class=oracle.jdbc.driver.OracleDriver ...
Log: Loaded JDBC Driver
Log: Connection with URL=jdbc:oracle:thin:@localhost:1521:xe as username/password
Error code not handled : 0
Exception Message :java.sql.SQLException: Listener refused the connection with the following error:
ORA-12519, TNS: no appropriate service handler found
The Connection descriptor used by the client was:
localhost:1521:xe
// End of log
And the Bundled Tomcat server automatically shuts down.
Again the System.out statements from the Connection Pool class constructor show that the cache has been initialized and that currently there are free connections available in the pool.
E.g.
Cache size = 18
Available Connections = 18
Cache Limit = 1000
Active size = 0
Has anyone faced anything similar? Could someone please suggest what I'm doing wrong here and what I should do to set right this problem?

Probably not... Oracle does not generally allow you to take data files from one machine and mount them on another machine.
If you have a small dump file (generally .DMP) and a handful of data files, you might have some transportable tablespaces, but it doesn't sound like that is the case.
If you have control files, you might have a closed database backup. If that were the case, you could do a database restore, but you would only be able to use the express edition if that was the original database version you took the backup from. It doesn't sound like you have control files, though, so I don't expect that you could do a recovery.
If the original database is still around, the easiest option would probably be to do an export from that system and an import into your new database (using the exp/imp or expdp/impdp tools depending on the source Oracle version).

what is the actual use of express edition???

Hi,
10g express edition (XE) is free database version of 10g. Application Express (Apex) is already installed to it.
Apex version that comes with XE is 2.1.
You can upgrade it to version 3.2.1 witch is latest one. New version of Apex comes with some nice features like interactive reports.
If you have installed XE you are ready to go developer Apex applications and practice Oracle database

Installing Discoverer with Database Version Oracle 10g Express Edition

Hello,
Is it possilbe to install Discoverer with database version Oracle 10g Express Edition? I have Oracle Fusion Middleware 11.1.1.1.0 on my Windows XP machine as well. If so, can someone please provide me a link to the Discoverer download.
Regards,
Kelly

Note that the Personal Edition of the database is 'the most powerful' version, in that it contains all features and options of the Enterprise Edition (expect RAC and Enterprise Manager packs)
As such, the Personal Edition, at a mere USD$400-500 is one of the most cost effective for-fee products that Oracle has in it's inventory. It is targeted at the developer. And it comes with the complete set of Sample Data, whereas XE has a very limited subset (since it does not support all functionality).
Express Edition is indeed free, but it is not supported, and can not be patched. OTOH it does have a lighter footprint.
Again, I am not sure whether Disco 11g is compatible with Express Edition. (It's on my schedule for December ...)

Initial Login Problems with Oracle 10g Express

Hi,
Can anybody help, im a student trying to use oracle 10g Express for a project, my problem is the express will not allow me to login as an administrator from the word go. I'm using the right user name and password and every time I login the page just refreshes itself with no other prompts. If i type the wrong credentials i get a message saying so and if using the Hr user name and password it says its locked as it should. Ive used the sql prompt to login and this works so i no the password and user name are correct, but id like to use the GUI if i could. Ive unistalled and reinstalled twice still no joy. Any suggestions?

Hey again, thanks for your replies, Yes i have been using SYSTEM and SYS with a password of oracle in the GUI interface. When i use the SQL prompt i use the following to login:
SQL> conn system/oracle
connected.
SQL> Show User
USER is "SYSTEM"
This says to me that i have logged into the database but still i have no luck in doing the same through the GUI interface using the same credentials.
