shell scripts do not exit once completed
Hi Gurus,

I have to perform some oracle database task so i have written a test scripts which open the database connection and perform a select . once it is done i want it to come out from data base to unix prompt which is not happening. the below command will be a part of shell scripts and once it is done shell will perform other task which are written after these lines of codes.

Code:
sqlplus -S ERS_SRC/ERS_SRC@ERS11G
select sysdate from dual;
EXIT;

Please suggect what to do

I wonder why this runs at all.

You should post the shell script you have troubles with, not some (eventually irrelevant) part of it.

Even in the part you posted there are some errors (hence the initial remark):

Code:
sqlplus -S ERS_SRC/ERS_SRC@ERS11G
select sysdate from dual;
EXIT;

The first line is directed to the shell, because it calls a program ("sqlplus") with some options. The second and third line are not directed against the shell, but against this called program - from where should the shell know that it has to redirect the text to this?

Here is what i suppose to happen: you start the script, it runs up to the line with "sqlplus", "sqlplus" starts and simply stands at the input prompt and the rest of the script is waiting for "sqlplus" to terminate - which never happens.

Do it the following way (it is called a "here-document"):

Code:
sqlplus -S ERS_SRC/ERS_SRC@ERS11G <<EOF
select sysdate from dual;
EXIT;
EOF

I hope this helps.

Hi I have put the code in my scripts but it gives me error
./load_rio.sh[58]: syntax error at line 59 : `<<' unmatched

Code:
dbpart () { 
sqlplus -S ERS_SRC/ERS_SRC@ERS11G << EOF
exec PROC_PARTITION_MGMNT;
EOF
}
dbpart;

my actual scripts is
Code:
cd /ersdg3/ERS/ERS_INPUT_LOGS/RIO/LOGS/$NEWDIR
#test -e *.LOG $1
#       if [$? ne 0]; then
        if [ -f *.LOG ]
        then
        for i in *.LOG
        do
                flnm=$i
                #echo "file name is $flnm"
        #sed  "s:e:$flnm{i}:g" /ersdg3/ERS/ERS_INPUT_LOGS/RIO/control/control.ctl > /ersdg3/ERS/ERS_INPUT_LOGS/RIO/control/controlnew.ctl

                echo " ...............Connecting......................"

        sqlldr ERS_SRC/ERS_SRC@ERS11G control = /ersdg3/ERS/ERS_INPUT_LOGS/RIO/control/rionew.ctl data = $flnm

                mv $flnm /ersdg3/ERS/ERS_INPUT_LOGS/RIO/rio_archive/$NEWDIR
                echo "files have been loaded .... $flnm"
        done
                echo ".....Please wait ..Zipping the logs file..."
##zip -r /ersdg3/ERS/ERS_INPUT_LOGS/RIO/rio_archive/$NEWDIR . -i *.LOG
        else
                echo "Files doesnt exist"
        fi
        if [ -f *.TXT ]
        then
                sqlldr ERS_SRC/ERS_SRC@ERS11G control = /ersdg3/ERS/ERS_INPUT_LOGS/RIO/control/rio_rec_cnt.ctl data = RIO_AUDIT_REC.TXT

# Create oracle partiton for every data once loader load the data
        dbpart () {
                sqlplus -S ERS_SRC/ERS_SRC@ERS11G << EOF
                exec PROC_PARTITION_MGMNT;
                EOF
        }
        dbpart;

please let me know what is the issue

Okay, I have just edited the script. I apologise.
Please see the full script:

The first thing is you have written

Code:
command .... << EOF

instead of

Code:
command .... <<EOF

notice the space character, which may be a problem.

further, you have indented the code, which is not entirely possible with here-documents: the closing "EOF" must be at the beginning of the line:

Code:
# this will work:
command .... <<EOF
text to send to command
EOF

# but this will not, because of the last line:
command .... <<EOF
    text to send to command
    EOF

You can use indented closing clauses if you prepend the opening clause with a minus sign:

Code:
# this will work:
command .... <<-WORKSTOO
   text to send to command
   WORKSTOO

but don't know if this is the case in ksh too, i only know for sure it works in bash.

I suggest you go over this script (which has some other design deficits too)
with someone knowledgeable to make it better written.

I hope this helps.
