Problem with Oracle database Express Edition (Linux)

I installed oracle-xe on my machine (ArchLinux x64), and all worked fine before a reboot. After it, I still can connnect to the db with sqlplus, but can't connect to apex (http://localhost:8080/apex/f?p=4950) and can't get a connection using ojdbc:
Exception in thread "main" java.sql.SQLRecoverableException: IO Error: The Network Adapter could not establish the connection.
I tried to reinstall the db several times, but the result was always the same: all is ok only before rebooting. I'm a newer with Oracle database and can't find a solution. Could you give me some tip about it?

The problem was solved by changing permissions for log directory :
sudo chmod -R 777 /usr/lib/oracle/product/11.2.0/xe/log

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.

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.

Login problem with Oracle 10g Express Edition as system user

I have installed Oracle Database 10g Express Edition, but I can not login inside. I use the following:
user: system
password: ****** the password witch I put during the installation.
As I click Login, the page returns to the same state and wants username and password again. As I write wrong user and pass it yields an error, as I write the right user and pass it returns to the same page again. I used uppercase for system and lower case, but the problem goes on. I read the documentation, but I didn't find a solution.
Eventully I may be miss something. Can anyone help me?

Installing SQLDeveloper with Oracle Database Express Edition 11g Release 2

Hello,
I have a problem with sqldeveloper in connecting to the database with the following message:
*"java.lang.unsatisfiedlinkerror oracle.jdbc.driver.t2cconnection.t2csetsessiontimezone"*
I can connect to the database via SQL / SQLPLUS. I cannot select from the dual table.
My machine is windows 7 - 64 -bit. I downloaded SQLDEVELOPER for 32-bit.
Thanks.
Jaffee

I downloaded the version without the JDK, because I already had Java on my machine. I will try with the JDK included.
New update: I download the version with the JDK. I recevied the same message. Do I need to delete the first version of Java?
Thanks.

How Users Interact with Oracle Database Express Edition in a Network?

Please i just want to know how users can relate or access the Oracle DB xpress on a network. Coming from an oracle enterprise edition background i know when you install oracle on a network, isqlplus for example is centrally loaded meaning you dont need to install oracle on each machine in the network, so users can access the DB from their nodes. I am presently working in a big estate management firm and i want to create a structured database for them, they use excel to store records and want to introduce Oracle.

You can access XE remotely through the browser after following the instructions here:
http://download.oracle.com/docs/cd/B25329_01/doc/admin.102/b25107/network.htm#BHCBCFBA
If you are using APEX as the application, you'd need to do that. There may be other firewall consideration though (ie opening the relevant server ports).
[There's no isqlplus anymore, but there is a similar sql worksheet in the Apex development environment).
If you are just using the database as a data store behind, for example, a Java application, then connections will probably be through ODBC/JDBC/OCI and probably need some client installation too.

Problem with Oracle 10g Express Edition

Hi,
Install OracleXE.exe in Windows 2000, but on having tried to enter the following mistake goes out: http://127.0.0.1:8080/apex
It is not possible to show the page
That is what happens
Thank you

You mention the default installation uses port 7777, then you mention that Apache is not used.
Minor correction to your posts:
1) The default installation for APEX uses Apache and defaults to port 7777;
2) The default installation of XE does not include Apache, and the built-in environment defaults to port 8080
Reference is the XE documentation, which supercedes the APEX documentation. That is found at http://www.oracle.com/pls/xe102/homepage
And for clarification, the HTTP service in XE is composed of 2 parts:
- the HTTP listener is handled by the Oracle listener, on the port registered using the "dbms_xdb.sethttpport();" procedure and reported using the "dbms_xpg.gethttpport()" function.
- the HTTP server is primarily in the dbms_epg package.

Upgrade oracle database express edition

good morning
i've a question i'm working with oracle database express edition but now the memory is full and i want to upgrade it to oracle enterprise edition but i don't know the steps please can you help me in this
best regards

I've a question i'm working with oracle database express edition but now the memory is full and i want to upgrade it to oracle enterprise edition Hi,
Not to dissuade you from that, but that's quite a leap from XE to EE, are you sure that SE One or SE would not be a 'better option' for you?
Also, by 'memory is full', I assume you mean you've reached the 4Gb data limit?

Creating a Database with Oracle 10 Express Edition

Is the Oracle Database Express Edition 11g Release 2 enough for preparing for the 1Z0-051 and 1Z0-144 Exams?

I am planning on getting certified as an OCA PL\SQL developer. I will be teaching myself and I have all the material needed to prepare.
Except, I don't have a database that I can solve exercises on and practice commands.
The two exams I will be taking are the :
1Z0-051 exam: Oracle Database 11g: SQL Fundamentals I
1Z0-144 exam: Oracle Database 11g: Program with PL/SQL
So is the Oracle Database Express Edition 11g Release 2 is enough ?
If it is not what other options do I have (I am running Windows 8.1) ?

Yes -- 11gXE should be sufficient for practicing the vast majority of the skills required for those two exams. I *think* that PARALLEL is not enabled in XE, so you could not test the functionality referred to in the "Use NOCOPY hint, PARALLEL ENABLE hint and DETERMINISTIC clause" topic of 1Z0-144. I don't consider that to be a significant problem, however. The material from the manual should suffice for the questions you'll see.
As for what other options you have, you could download and install VirtualBox (free from Oracle). You could then make a virtual machine on your Windows 8.1 machine and install Oracle Linux (free from Oracle). You could then download and install Oracle Enterprise for Linux and install it on your virtual machine (allowable under the licensing when used for learning purposes only). I have a similar setup on my Windows 7 laptop that I use when I absolutely have to test some feature that requires Oracle Enterprise. Mind you, when I have the VM running on my system... it is ssssslllllloooooowwwwww because of the memory requirements. I talk about using virtual machines as a certification aid in the following article:

Does Oracle Database Express Edition 11g support CLOB datatype?

I am having problems in displaying CLOB data type columns when I query my tables in Oracle Database Express Edition 11g. I am getting garbage values. However when I do the exact same thing in the Enterprise Edition I do not have any problems. So I am thinking that the Express Edition does not support CLOB data types due to its size limitations. Am I missing something here?

Hi, and welcome to the OTN forums!
I download a year ago oracle 10g and installed in windows7/64bit.
Now 11g is available. But it says does not work in x64.Well, in fact, 10.2 XE wasn't certified for x64 either, not even for Linux x64...
11.2 XE has a Linux x86_64 release, and there has been an announcement that there'll be a x64 release for Windows as well, but it's not available (yet).
There have been a lot of reports that people got 11.2 XE work on x64 Windows machines as well, with a few tweaks at installation time and/or afterwards...
You'll find tons of posts on that topic when using forum search...
oracle 10g seems to be not available anymore.Right, the official downloads have been removed after all database 10.2 releases fell out of (regular) support.

Installing Oracle Database Express Edition 11g on UBUNTU

Hello everyone,
I want to install Oracle Database Express Edition 11g on UBUNTU. I followed the steps from this link created by Dude:

Downloading Oracle Database Express Edition

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,

hi again. first a have to apologize. i have oracle
database express edition 10g from school,so i dont
have registered version.When I said 'register' I didn't mean have it licensed, Oracle XE doesn't require any kind of license registration, it is free. By registering it I meant a technical issue. Once the database is started it tries to contact the listener at 1521 port, once contacted the oracle instance registers itself against it, and if it is successful you will have the administrator's page initialized and ready to access at the default 8080 port.
when i type SQL commands, command line wrote me
SP2-0734:unknown command beginning ENTERED COMMAND
Could you please specify which command did you try to enter?
>
and when i open RUN DATABASE, command line wrote
C:\OracleDatabase\app\oracle\product\10.2.0\server\BIN
net started OracleServiceXE - system error 5, accessdenied
What do you mean with 'RUN DATABASE'?
