How to reconfigure Oracle-xe (Oracle 10g for linux)?

Question

Hello!
I found this article (seems useful since I use Mandriva 2010.2):
[http://www.e-angel.net/index.php?tg=articles&idx=Print&topics=195&article=912|http://www.e-angel.net/index.php?tg=articles&idx=Print&topics=195&article=912]
I installed Oracle 10g from the file "oracle-xe-univ-10.2.0.1-1.0.i386.rpm".
Then, when run ./oracle-xe start and then ./oracle-xe status I get:
LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 29-JUL-2011 23:39:49
Copyright (c) 1991, 2005, Oracle.  All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC_FOR_XE)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 2: No such file or directory
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=%hostname%)(PORT=%port%)))
TNS-12545: Connect failed because target host or object does not exist
TNS-12560: TNS:protocol adapter error
TNS-00515: Connect failed because target host or object does not exist
It does not seem ok to me.
I would love to truy to reconfigure it but if I try the command:
./oracle-xe configure
...I get:
Oracle Database 10g Express Edition is already configured
Does any body know how to reset and reconfigure Oracle 10g for Linux?
Best regards
Fredrik

Answer 1

it seems to be "PLSExtProc" bu default.Nope, the ORACLE_SID is taken from the environment variable when the database is started on a *nix host, windows its set up in the database service. If you want to change the ORACLE_SID, set it. See the environment setup script in OH/bin appropriate for your shell. (OH short for $ORACLE_HOME)
