Execute Oracle pl/sql commands in a scrit using nohup
Good afternoon:
I need your help please, Im new at Unix nd specially Unix applicationas like oracle and Ive got this problem:

I was asked to execute the next script using nohup in order to not hang up the session because it was supposed to connect to the database and then insert about 2 millions of rows to a table
and this process akes about 2 hours

I run this script with oracle user because of privilige issues previusly exporting some oracle vars

Code:
export ORACLE_SID=XYZ
export TWO_TASK=XYZ

SCEL:/oracle/oracle/PACKAGES/CXYZ/Install oracle@prosclbt00c # id
uid=1000(oracle) gid=26(dba)

nohup ./install_bd.ksh &

But after 12 hours or more this process continue writing both logs consuming so much space

Code:
-rw-------   1 oracle   dba         1.8G Dec  8 12:23 nohup.out
-rw-r-----   1 oracle   dba         1.8G Dec  8 12:23 install_1_0_SCEL.log

Sadly, we validate with our DBA if there was any session but he said there was neither session with OSUSER oracle nor any other sessions affecting the specified tables.

So it was likely the process was redirecting the output to both logs but it never connected to the DATABASE, dont know for sure:

This is the scriptinstall_bd.ksh

This is the scriptinstall_bd.ksh

Code:
 more install_bd.ksh
#!/bin/ksh
# Descripcion: ASB
# Cambio de:
#       


time sqlplus /<<EOF
set echo on verify on feedback 1 timing on time on pages 10000 lines 132 trimspool on tab off flush off
/
WHENEVER SQLERROR CONTINUE
set echo on verify on feedback 1 timing on time on pages 10000 lines 132 trimspool on tab off flush off

spool install_1_0$1_$ORACLE_SID.log

@install_1_0.sql

spool off
disconnect
EOF

resultado=$(egrep "ORA-|PLS-|SP2-" sclsql_$1_$ORACLE_SID.log |grep -v "ORA-00001" | grep -v "ORA-01430" |grep -v "ORA-01921" | grep -v "ORA-01920" |sort -u > final.log)

hay_error=`wc -l final.log | awk '{ print $1 }'` 

ls -ltr *.log
cat final.log
rm final.log
echo "ERRORES ENCONTRADOS "$hay_error
exit

The questions are:

1. I would like to know it was something wrong executing the scrpit install_bd.ksh & using nohup?

2 if so how to control the proceses can not hang up? wouldnt it better to modify inside the script install_bd.ksh this line:

Code:
nohup time sqlplus /<<EOF ?

I'd appreciate your help in advanced

nohup

NICE(1) 						      General Commands Manual							   NICE(1)

NAME

       nice, nohup - run a command at low priority (sh only)

SYNOPSIS

       nice [ -number ] command [ arguments ]

       nohup command [ arguments ]

DESCRIPTION

       Nice  executes  command	with low scheduling priority.  If the number argument is present, the priority is incremented (higher numbers mean
       lower priorities) by that amount up to a limit of 20.  The default number is 10.

       The super-user may run commands with priority higher than normal by using a negative priority, e.g. `--10'.

       Nohup executes command immune to hangup and terminate signals from the controlling terminal.  The priority  is  incremented  by	5.   Nohup
       should  be invoked from the shell with `&' in order to prevent it from responding to interrupts by or stealing the input from the next per-
       son who logs in on the same terminal.

FILES

       nohup.out standard output and standard error file under nohup

SEE ALSO

       csh(1), setpriority(2), renice(8)

DIAGNOSTICS

       Nice returns the exit status of the subject command.

BUGS

       Nice and nohup are particular to sh(1).	If you use csh(1), then commands executed with ``&'' are automatically immune  to  hangup  signals
       while  in  the  background.   There  is	a builtin command nohup which provides immunity from terminate, but it does not redirect output to
       nohup.out.

       Nice is built into csh(1) with a slightly different syntax than described here.	The form ``nice +10'' nices to positive nice,  and  ``nice
       -10'' can be used by the super-user to give a process more of the processor.
