Listener cannot start in RHEL3U7

Question

I installed yesterday Oracle 10.2 and it workerd fine. Then I rebooted the machine and now Oracle does not start.
The problem is related to listener. lnsrctl start shows these messages:
Message 1070 not found; No message file for product=network, facility=TNSTNS-12545: Message 12545 not found; No message file for product=network, facility=TNS TNS-12560: Message 12560 not found; no message for oproduct=network, facility=TNS TNS-00515; No message for product=network, facility=TNS
Linux error 2: No such file or directory
Thanks in advance

Very simply ...
nearly all of the Oracle components look for their eror message language files from the $ORACLE_HOME/component/mesg directory. If the files are not in the expected directory, tyhen you get a 'message file not found' error.
The check is very, very simple - do the following at command line (do NOT replace $ORAZCLE_ORACLE_HOME - cut and paste)
cd ~
ls $ORACLE_HOME/network/mesgif that results in something like the following, we need to look at other possible problems. But in general, 99.9999% of the time, I have found that a) the $ORACLE_HOME is not set right and b) arguing about it doesn't help
pop2@fuzzy:~> ls $ORACLE_HOME/network

pop2@fuzzy:~>The easiest trick to get this set is:
1) make sure the /etc/oratab file contains a line lile
XE:/usr/lib/oracle/xe/app/oracle/product/10.2.0/server:N
for each instance you want to start. The fields are:
SID:path-to-Oracle-Home:start/stop-using-dbstart/dbshut{Y/N}
2) include the following in some profile (/etc/profile, ~/.profile, ~/.bash_profile)
export ORACLE_SID=orcl
ORAENV_ASK=NO
. /usr/local/bin/oraenv.sh
(teh oraenv shell must be sources, not executed. It is located in the directory you specified using the root.sh command at the end of the install - default = /usr/local./bin. The file name may be oraenv.sh, oracle_env .sh, or some similar one. Those ending in .csh are for the C-shell
