I have a .sh file which contains


. $SVEN_HOME/config/configurator.cfg



sqlplus $leninlogin  @$general_weekly/ACE2_HISTORY/ACE2_History.sql



I want to add a log file to track the log of job completion?

This .sql file simply truncates a table and it will be automated in control M tool.

But please advice how to write the script for log creation and with proper message.

Thanks

Just try it (">>").

Better use "sqlplus -s" to avoid SQL*Plus banner.

When you run the command interactively, do you get the output you want on the screen? If not, you may need to modify the sql script to stop it from suppressing the output.

Try something like this:

-- set termout off
set echo off
set time on
select user, global_name from global_name;
prompt Truncating table 1 now...
truncate table xyz;

It tells that the value of "filename" column in next queries will be put inside a SQL*Plus substitution variable named "filename" (which is used using "&filename").

How to put this for my unix script??

this is my .sh file
. $SVEN_HOME/config/configurator.cfg



sqlplus $leninlogin  @$general_weekly/ACE2_HISTORY/ACE2_History.sql


Quote:
sqlplus $leninlogin
here it connects to data base
and the .sql file goes like this

PROMPT '**************************************************'
PROMPT 'cleaning the deleted lists from ACE2_DELETED_LIST '
PROMPT '**************************************************'


truncate table ACE2_DELETED_LIST;

exit;


Now where to write the select query and then the spool one??


Please advice??

Thanks Michel

Quote:
The clean up job is complete


and if error then as usual the error message??


Please advice

there is only one statement

truncate table ACE2_DELETED_LIST;



PROMPT '**************************************************'
PROMPT 'Generating Log File
PROMPT '**************************************************'

col filename new_value filename
SELECT 'ACE2_DELETED_LIST_'||TO_CHAR(SYSDATE,'YYYYMMDDHH24MISS')||'.log' filename
FROM DUAL;




PROMPT '**************************************************'
PROMPT 'cleaning the deleted lists from ACE2_DELETED_LIST '
PROMPT '**************************************************'


Begin

spool &filename

truncate table ACE2_DELETED_LIST;


spool off

exit;

This is the current code where the table truncated message is comming to the log file in case of success and in case of failure the error message

hence it should have the user defined message in case of success and error message in case of error

First remove "Begin" line, then:

PROMPT '**************************************************'
PROMPT 'Generating Log File
PROMPT '**************************************************'

col filename new_value filename
SELECT 'ACE2_DELETED_LIST_'||TO_CHAR(SYSDATE,'YYYYMMDDHH24MISS')||'.log' filename
FROM DUAL;

whenever sqlerror exit 1
set feedback off

PROMPT '**************************************************'
PROMPT 'cleaning the deleted lists from ACE2_DELETED_LIST '
PROMPT '**************************************************'

spool &filename

truncate table ACE2_DELETED_LIST;

prompt Success!

spool off

exit;

This is what i face

Say in case of any error,Then this prompt is comming always
even if error is there

Now for testing i dropped the table and ran the
.sh file below

. $SVEN_HOME/config/configurator.cfg



sqlplus $leninlogin  @$general_weekly/ACE2_HISTORY/run_delete_list.sql


This is the sql script below

PROMPT '**************************************************'
PROMPT 'Generating Log File
PROMPT '**************************************************'

col filename new_value filename
SELECT 'ACE2_DELETED_LIST_'||TO_CHAR(SYSDATE,'YYYYMMDDHH24MISS')||'.log' filename
FROM DUAL;




PROMPT '**************************************************'
PROMPT 'cleaning the deleted lists from ACE2_DELETED_LIST '
PROMPT '**************************************************'

set feedback off


#spool &filename



truncate table ACE2_DELETED_LIST;



prompt 'success!!'


spool off



The log file created goes below


cat ACE2_DELETED_LIST_20080530042741.log
truncate table ACE2_DELETED_LIST
               *
ERROR at line 1:
ORA-00942: table or view does not exist


'success!!'


The success should only come in case of success?

PLease advice?

Thanks

Apologise for the mistake


but here are a few questions please advice

Quote:
whenever sqlerror exit 1


what will this do?

secondly when i execute the .sh file,if it is success then it shows the success prompt and the file creation as well but when it is a failure then
this error message should only reflect in the log file and just a message to us that it failed and please check the log file for details


the currect senario below??

sh deletelist.sh

Yes this was what i wanted,Thanks
but if you can see my previous mail carefully,i wanted the additional thing which actually makes better redeability of the code


Quote:

this error message should only reflect in the log file(the user executing the .sh script should get just a message that it failed and please check the log file for details,and as it is happening now the error is there in the log file but the same thing is also appearing in the shell while executing the .sh file)

Ok i will try

if any one can understand what i mean please let me know

I don't want that oracle error message in the unix shell to be displayed while executing the .sh file,in case of failure it should only redirect it to the log file and for the user it should only display "process failed and check log"

something like this

being new to unix i am not sure how to implement this in the existing file of mine and hence need some assistance

Thanks

Lastly one major problem in the solution provided by Michel

The error can also be in the oracle connection also in case of wrong username and pwd,so in that case how will this work,as this generates the log only after proper connection in oracle.

Thank god it strike me,otherwise it would have been problem in production..

One trick is to put a final spool at the end of the sql to act as a flag file. If the sql script gets to the end, it didn't exit prematurely. You obviously remove old flag files before the next run...
whenever sqlerror exit 1
spool my_main_log.log
...
...
spool end_was_reached_ok.flg


Try this though, works fine for
1)sqlplus not found,
2)wrong user/pass,
3)oracle error in sql statement etc...
#!/usr/bin/ksh
user=scott
pass=tiger
db=devdb

t_name=xyz
log=my_log`date '+%Y%m%di'`.log

##sqlplus -s /nolog <<EOF >$log
sqlplus -s /nolog <<EOF >/dev/null
  whenever sqlerror exit 1
  connect $user/$pass@$db
  truncate table $t_name;
EOF
rv=$?

echo Retval is $rv

if [ $rv -eq 0 ]; then
  echo "Successfully truncated $t_name"
else
  echo "ERROR. Failed to truncate $t_name"
fi

exit $rv

Hi Andrew.

This is superb,many thanks

Here is my current code,but i am getting error.Please also advice on the doubts,thanks


. $SVEN_HOME/config/configurator.cfg

LOG_FILE=$general_weekly/ACE2_HISTORY/ACE2_DELETED_LIST_`date '+%Y%m%di'`.log

sqlplus -s  <<EOF >$LOG_FILE
#sqlplus -s /nolog <<EOF >/dev/null
whenever sqlerror exit 1
connect  $leninlogin

#sqlplus sven_lenin_prod/sven_lenin_prod@edw2

truncate table ACE2_DELETED_LIST;

EOF
rv=$?

echo Retval is $rv

if [ $rv -eq 0 ]; then
echo "Successfully Truncated"
else
echo "ERROR. Failed to complete the process"
fi

exit $rv


Quote:
$SVEN_HOME/config/configurator.cfg


Here i have the connection settings in the .cfg file

Quote:
sqlplus -s <<EOF >$LOG_FILE


Is this correct and then touch log file

because i want the error or success also in the log file??

secondly in this code this is what i get as error in log file

sh  new_createwithlog.sh
Retval is 1

what will these statements do

Hi Andrew

This is my current code.It is working fine.I suppose i am doing it rightly

But this is the only error i am getting in log file

cat ACE2_DELETED_LIST_20080531.log
SP2-0734: unknown command beginning "sqlplus -s..." - rest of line ignored.
'Successfully Truncated'


Why is this the case?
and what will sqlplus -s do here?

There are two "EOF" tags (you can use just about any string you want). They form a "here document" structure in shell scripting. Take care not to indent the second one in KSH it must be in the first colum. Everything between the tags is basically what you'd normally have in a separate sql script.

The commented out line (#sqlplus...) falls withing the here document, so SQLplus gets it and doesn't know what to do with it. You can comment something in sql using "--" rather than "#".

/dev/null is a null sink. You redirect output that you aren't intrested in seeing to it.

No need to touch the file first - that just creates an empty file if it doesn't already exist.

If you really want a SQL log, then use all the propmts, etc that you're interested in and redirect to your log, then just cat the log when error is detected.

rv=return value. $? always contains the return code of the last statement you ran in KSH. You capture it into a variable to ensure that you don't accidentally look at $? for the wrong statement, like say an echo (that you put in for debugging)before checking the return code.

Try something like this (untested)
. $SVEN_HOME/config/configurator.cfg

LOG_FILE=$general_weekly/ACE2_HISTORY/ACE2_DELETED_LIST_`date '+%Y%m%d'`.log
touch $LOG_FILE
sqlplus -s /nolog<<EOF >$LOG_FILE
whenever sqlerror exit 1
connect  $leninlogin

set echo off
prompt Trying to truncate ACE2_DELETED_LIST now...
truncate table ACE2_DELETED_LIST;

EOF
rv=$?

#echo Retval is $rv

if [ $rv -eq 0 ]; then
  echo "Successfully Truncated"
else
  echo "ERROR. Failed to complete the process"
  cat $LOG_FILE
fi

# exit with return code, so that your scheduler knows
# if this script failed (1-255) or succeeded (0)
exit $rv


Unix return code is limited to 1 byte
Oracle return codes are almost always negative numbers (e.g. ORA-01012 value is -1012, so don't try returning "whenever sqlerror exit SQL.SQLCODE"
