UNIX for Dummies Questions & Answers

Oracle92 on solaris 8.

We have a Truncate Script that runs every night to cleanup certain tables , so new data gets loaded into. This Script is run in Unix Shell script where i set Environment varibles, and things like that..

Now, how do i create a log file of the script , to see weather the script really deleted the data ?

==========================
#!/bin/ksh
ORACLE_BASE=/u10/app/ORACLE
ORACLE_DOC=$ORACLE_BASE/doc
ORACLE_HOME=$ORACLE_BASE/product/9.2.0.1.0
ORACLE_SID=dss
PATH=/usr/bin:/usr/ucb:/usr/sbin:/etc:/usr/inform/PowerMart:/usr/inform/RepServer:/usr/inform/scripts:$ORACLE_HOME/bin:/usr/bin:/bin:/usr/ccs/bin:/usr/ucb:/etc:/usr/openwin/bin:/usr/local/bin:.
TNS_ADMIN=$ORACLE_HOME/network/admin
LD_LIBRARY_PATH=/usr/inform/PowerMart:/usr/inform/RepServer:$ORACLE_HOME/lib32
export PATH PM_HOME ORACLE_BASE ORACLE_HOME ORACLE_SID LD_LIBRARY_PATH TNS_ADMIN
export PARMS=/usr/inform/scripts/WorkFlow/dss_parms
ORADBUSER=`cat $PARMS |grep ORADBUSER|cut -d":" -f2`
ORADBPASSWD=`cat $PARMS |grep ORADBPASSWD|cut -d":" -f2`

$ORACLE_HOME/bin/sqlplus -s << EOF
$ORADBUSER/$ORADBPASSWD
set heading off;
set feedback off;
set echo off;
truncate table current_year;
commit;
=============================

The simplest way, assuming you are using cron to run the script is to redirect the cron job stdout and stderr to a file.

Dear

if you are runnning the script from crontab,then the output will be mailed to the owner user.

also you can put the script output in one file and the error in another one as below

your_script.sh > outfile 2> errfile

i see in your script that you do "set echo off", however it is related to oracle ,to see the truncate command output set echo on so you will findout weather it truncate the table or not
