Oracle 10g Express Edition problem

[Migrated From Jforum.net]

I hope someone can help me on this.

I've installed Oracle 10g Express Edition on a Linux box, for development and testing purposes, but still cannot make jForum work with it.

It seems Oracle 10g EE uses a single database, and you must use one schema for each application. The thing is I haven't been able to install jForum using this approach.

The installer shows this:

java.sql.SQLException: Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=169869568)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))

Obviously Im doing something wrong. I created the username/passwd jforum/jforum, but Im not sure what to put in the dbname, because of the schema approach.

Any ideas?

The dbname is "xe"

Thanks for your comment. That is true, but actually my problem was that the "XE" instance was no properly set. For those with the same problem, look at this link:
http://www.davidpashley.com/articles/oracle-install.html

If still not working, check if the lsnrctl (utility that manages the Oracle listener processes) is up:

su - oracle
lsnrctl status

if doesn't find lsnrctl, or you get permission problems, or any other issue, you have to set up your oracle env:

su - oracle
export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server
export ORACLE_SID=XE
export NLS_LANG=$ORACLE_HOME/bin/nls_lang.sh
PATH=$ORACLE_HOME/bin:$PATH
export PATH
if [ $?LD_LIBRARY_PATH ]
then
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
else
LD_LIBRARY_PATH=$ORACLE_HOME/lib
fi
export LD_LIBRARY_PATH

And now check it

lsnrctl stop
lsnrctl start
lsnrctl status

You should see now your Oracle instances, and connect easily with the resource USER/PASSWD@INSTANCE

sqlplus myuser/mypasswd@xe

Hope it saves someone time...
