How to install and configure Oracle 10g Express Edition on Fedora 11?

Question

Hi everyone!
I have recently installed Oracle 10g XE on my Laptop Gateway T-1625, which has Fedora 11.
I followed the install instructions on [http://st-curriculum.oracle.com/tutorial/DBXETutorial/index.htm] , and configured the server as explained, but something is wrong... When I try to go to the database home page http://127.0.0.1:8080/apex, I get "Failed to Connect" on Firefox 3.5b4... I don't think it's because of the Firefox version because it's proved to be very stable (for a beta).
I've search for similar issues on GNU/Linux and I found this thread in these forums: [ http://forums.oracle.com/forums/thread.jspa?threadID=915218&tstart=0] , but the solution is for Ubuntu 9.04, and if it's possible I would like to know a specific solution for Fedora 11.
I also tried to see the oracle server status with:
# /etc/init.d/oracle-xe status
And I got this....
LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 25-JUN-2009 22:10:31

I hope someone can help me out and guide me on the right direction. Thanks a lot!

Hi again!
After your last post I realized that the dba group and the oracle user already existed.
#groupadd dba
groupadd: group dba exists
#useradd oracle -d /home/oracle -s /bin/bash -g dba
useradd: user oracle existsHowever, I finally assigned a password for that account and changed the ownership of the /usr/lib/oracle/xe
with the commands you suggested:
passwd oracle
chown -R oracle:dba /usr/lib/oracle/xeAfter this, I can log in as the oracle user but the SELinux showed a warning and the /usr/lib/oracle/xe
is treated as the oracle home, and no .bashrc file is located on this home. This is the SELinux warning:
SELinux is preventing gdm-session-wor (xdm_t) "write" to /usr/lib/oracle/xe (lib_t).
Details:
SELinux denied access requested by gdm-session-wor. /usr/lib/oracle/xe may
be a mislabeled. /usr/lib/oracle/xe default SELinux type is user_home_dir_t, but its
current type is lib_t. Changing this file back to the default type, may fix your problem.
File contexts can be assigned to a file in the following ways.
  * Files created in a directory receive the file context of the parent
    directory by default.
  * The SELinux policy might override the default label inherited from the parent directory
by specifying a process running in context A which creates a file in a directory
labeled B will instead create the file with label C.
    An example of this would be the dhcp client running with the dhclient_t type and
creates a file in the directory /etc. This file would normally receive the etc_t type due
to parental inheritance but instead the file is labeled with the net_conf_t type
because the SELinux policy specifies this.
  * Users can change the file context on a file using tools such as chcon, or restorecon.
This file could have been mislabeled either by user error, or if an normally confined
application was run under the wrong domain.
However, this might also indicate a bug in SELinux because the file should not have
been labeled with this type.
If you believe this is a bug, please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
Allowing Acces:
You can restore the default system context to this file by executing the restorecon command.
restorecon '/usr/lib/oracle/xe', if this file is a directory, you can recursively restore using
restorecon -R '/usr/lib/oracle/xe'.
Fix command:
restorecon '/usr/lib/oracle/xe'I suppose the command #useradd oracle -d /home/oracle -s /bin/bash -g dba is where I can define the user's home, but if this user already exists how can I modify its settings?
is SELinux preventing the .bashrc file to be created? or what could be causing this?.
I hope you know how much I appreciate your help and want to thank you for your time.
