Vaildation in UNIX script

Hi,
I have a UNIX script which has two parts:
1. It connects to a database and refreshes a materialized view
2. It then connects to another database and inserts refresh statistics to a table

The script works, but I'm not too good at UNIX validation. Currently, if the first part of the job fails - the entire script bombs out.
What I would like it to do is, if the first part fails, then continue with the second part of the script, but still record an overall failure in the log file.

Below is the code at present. I think I need some conditionsal 'flags' but do not know where to begin. Please can someone help? See below:

. /usr/opt/oracle/cron/set_oraenv
. ${SCRIPT_DIR}/set_connect_params
export TOP_SCHEMA=${TOP_LOG}
export WHSE_SCHEMA=${VIW_LOG}
LOG_DIR=${SCRIPT_DIR}/logs
SCHED_DATE=`date "+%y%m%d"`
JOBSET_LOG=${LOG_DIR}/RUN_ROT_TOP_OCRS_MV_LOG_"$ENV"_$SCHED_DATE
export JOBSET_LOG
export LOG_DIR

echo "`date`: Refresh of ROT_TOP_OCRS_MV started" >> ${JOBSET_LOG}
#################################################################################
#
# Run the refresh of the ROT_TOP_OCRS_MV materialized view and then gather stats.
# Finally, insert an entry to COM_TABLE_LOAD_HIST to log the MV refresh.
#

sqlplus -s ${TOP_LOG}/${TOP_PW}@${TOP_SID} <<END1>> ${JOBSET_LOG}

whenever sqlerror exit 2
whenever oserror exit 3
set heading off
set serveroutput on

select 'User ID: '||user||CHR(13)||CHR(10)||'Connected to: '||rtrim(global_name,'.US.ORACLE.COM.ATOSORIGIN') from dual,global_name;
select to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') from dual;

execute DBMS_OUTPUT.PUT_LINE('*** Now running the weekly ROT_TOP_OCRS_MV materialized view refresh ***');
execute DBMS_MVIEW.REFRESH('${TOP_SCHEMA}.ROT_TOP_OCRS_MV');

select to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') from dual;
execute DBMS_OUTPUT.PUT_LINE('*** Now gathering statistics ***');
exec DBMS_STATS.GATHER_TABLE_STATS(ownname => '${TOP_SCHEMA}',tabname => 'ROT_TOP_OCRS_MV',cascade => TRUE);

select to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') from dual;

exit
END1

if [ $? -ne 0 ]
then
echo "`date`: Refresh of ROT_TOP_OCRS_MV failed" >> ${JOBSET_LOG}
exit 3
else
echo "`date`: Refresh of ROT_TOP_OCRS_MV completed successfully" >> ${JOBSET_LOG}
fi

sqlplus -s ${VIW_LOG}/${VIW_PW} <<END1>> ${JOBSET_LOG}

whenever sqlerror exit 2
whenever oserror exit 3
set heading off
set serveroutput on

select 'User ID: '||user||CHR(13)||CHR(10)||'Connected to: '||rtrim(global_name,'.US.ORACLE.COM.ATOSORIGIN') from dual,global_name;

execute DBMS_OUTPUT.PUT_LINE('*** Now inserting record stats to COM_TABLE_LOAD_HIST ***');
insert into COM_TABLE_LOAD_HIST
select 'ROT_TOP_OCRS_MV',count(*),null,null,null,null,sysdate,'ROT_TOP_OCRS_MV last refreshed on '||to_char(sysdate,'DD-MON-RR') from ROT_TOP_OCRS_MV;
commit;

select to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') from dual;

exit
END1

if [ $? -ne 0 ]
then
echo "`date`: Refresh of ROT_TOP_OCRS_MV failed" >> ${JOBSET_LOG}
exit 3
else
echo "`date`: Refresh of ROT_TOP_OCRS_MV completed successfully" >> ${JOBSET_LOG}
exit 0
fi

Remove the exit 3 from both the following 'if' statements:

Code:

if [ $? -ne 0 ] 
then
  echo "`date`: Refresh of ...etc.. failed" >> ${JOBSET_LOG}
  #exit 3  <== comment out here
else
  echo "`date`: Refresh of ...etc.. completed successfully" >> ${JOBSET_LOG}
fi
