Problem solved
Hi,
Thanks for the info.
The problem got solved as follows.
the script was as follows
-------------------------------------------------------------
..
..
..
spout=`sqlplus -s $UP <<EOJ
SET HEAD OFF
SET AUTOTRACE OFF
WHENEVER SQLERROR EXIT 255
ALTER TRIGGER schema.trg DISABLE;
DECLARE
v_alter_statement VARCHAR2(255);
CURSOR c_constraint_name IS
SELECT constraint_name
FROM dba_constraints
WHERE table_name = 'XXXX';
BEGIN
FOR REC IN c_constraint_name
LOOP
v_alter_statement := 'ALTER TABLE XXXX';
v_alter_statement := v_alter_statement || ' ENABLE CONSTRAINT ';
v_alter_statement := v_alter_statement || REC.constraint_name;
DBMS_UTILITY.EXEC_DDL_STATEMENT(v_alter_statement);
END LOOP;
Exception
when OTHERS then
Rollback;
dbms_output.put_line ('Script failed : Sqlcode: ' || SQLCODE || ' Error message :' || SQLERRM);
return;
END;
/
EOJ`
ret_code=$?
echo "$spout" >>${logfile} 2>&1
if [ $ret_code -ne $SUCCESS ]
then
cat ${logfile}
exit $FATAL
fi
..
..
..
----------------------------------------------------------------
now what was happening was that if there is a pl/sql block in a script then whole of it is executed in one go (that's what a pl/sql block is supposed to mean , poor me didn't remember). now i had by mistake given an extra quote(') in the dbms_output.put_line of exception block. this raised an error. now if u give dbms_output.put_line b4 and after declare the one b4 declare gets printed but not the one after. so i was inferring that the control never reached inside the declare statement. whereas it did reach inside but the pl/sql block failed at the dbms_output.put_line in exception block!!!!
also i was getting directory listing of the directory in which i ran this script in the log file if the script failed. this was happening becaue i had the following statemnt
echo $spout >>${logfile} 2>&1
now the var spout had * in it since al the output of sql is directed into it and the procedure failed or in case some pl/sql error occured.
makin this statement as
echo "$spout" >>${logfile} 2>&1
made it fine.
Thanks n Regards
Manish

SCRIPT(1) BSD General Commands Manual SCRIPT(1)
NAME
script -- make typescript of terminal session
SYNOPSIS
script [-akq] [-t time] [file [command ...]]
DESCRIPTION
The script utility makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an
interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
If the argument file is given, script saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
If the argument command is given, script will run the specified command with an optional argument vector instead of an interactive shell.
The following options are available:
-a Append the output to file or typescript, retaining the prior contents.
-k Log keys sent to program as well as output.
-q Run in quiet mode, omit the start and stop status messages.
-t time
Specify time interval between flushing script output file. A value of 0 causes script to flush for every character I/O event. The
default interval is 30 seconds.
The script ends when the forked shell (or command) exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-D (if
ignoreeof is not set) for the C-shell, csh(1)).
Certain interactive commands, such as vi(1), create garbage in the typescript file. The script utility works best with commands that do not
manipulate the screen. The results are meant to emulate a hardcopy terminal, not an addressable one.
ENVIRONMENT
The following environment variable is utilized by script:
SHELL If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not set, the Bourne shell is assumed. (Most
shells set this variable automatically).
SEE ALSO
csh(1) (for the history mechanism).
HISTORY
The script command appeared in 3.0BSD.
BUGS
The script utility places everything in the log file, including linefeeds and backspaces. This is not what the naive user expects.
It is not possible to specify a command without also naming the script file because of argument parsing compatibility issues.
When running in -k mode, echo cancelling is far from ideal. The slave terminal mode is checked for ECHO mode to check when to avoid manual
echo logging. This does not work when in a raw mode where the program being run is doing manual echo.
