i want to create a cron job for export.
the command runs properly when executed on shell prompt.
but cron gives exp:0056 and ora:12154 error( tns)
"could not resolve service name"
why should it need tns for local access?
i even created a tns entry just to check but still didn't work.

what does your cron do ???
if you do not do something like :
sqlplus login/password@instance << EOF
...
EOF
then it will try to connect using SQL*Net ...

my cron calls a batch file that sets
some vaiable like sid,oracle_home
then uses export cmd
exp parfile=<> file=<>
parfile is in my backup directory.
with userid=name/pwd
the same batchfile executes properly from cmd line.

ok, ok, ok ... so here are some ideas :
1st and most important) CHECK YOUR ENV !!
be VERY careful because when using cron, you rarely have the environment you think you have. if you're using root crontab, what I usually do is, in the crontab, call a shell like :
10 12,14 * * 1-6 /home/dir1/dir2/launch my_script.sql >/dev/null 2>&1
that way you call a script called launch, which just does :
-----
FILE=$1
export ORACLE_HOME; ORACLE_HOME=...
su oracle -c "$ORACLE_HOME/bin/sqlplus -s user/pwd @$FILE"
-----
that way I am sure that my env is correct.
I guess you can do exactly the same using exp instead of sqlplus, the idea is just to be sure that the env is correct
2) check you have enough space left on device to create dump file
3) check that listener.ora file does not contain GLOBAL_DBNAME parameter

thanks pipo!
when i added oracle_owner env to my batch file it worked out.
earlier i was using only oracle_home and oracle_sid
i also added shlib_path
