Launching SQL*Loader from within PL/SQL procedures

[DavidLeGallez]

We have a requirement to automate a data load process that is currently being launched manually. I have been looking into several options including using the OCI to make a call to SQL*Loader. We are using Oracle 8i (8.1.7) on a SUN box (Solaris 5.8).

We are looking at having a process (possibly PL/SQL) check for the existance of the raw data file (a fixed length text file). If the file exists then the process would call SQL*Loader, with associated arguments, to load the file into the database. Upon success the process would then execute additional data validation and data manipulation batch processes that are written
in PL/SQL packages.

We are still investigating options but I was hoping someone else out there has done this. Any comments are welcome. How did you do it? What did you have to do to DB parameters and OS config to get it to work? What challenges did you have? etc.

Thanks

If there is no other option (like using ext proc) u can use the host command to invoke sql loader to populate.

The easiest way to do such things is creating a shell-script in Unix,
that will check if a file exists and then start sql-loader.
The script can be scheduled in the CRONTAB.
Something like this:
#!/bin/sh
function LoadFile
{
# Start SQL loader

sqlldr userid=user/passwd \
control=$CNTL_FILE \
data=$DATA_DIR/$1 \
log=$LOG_DIR/$1.log \
bad=$BAD_DIR/$1.bad \
discard=$DSC_DIR/$1.dis \
rows=100000 >> $vLogFile
trc=$?


return 0;
}
########### Here it starts ###########
filetypes=`cat $FILE_DIR/cmafiles.lis`

for currtype in $filetypes
do
LoadFile $currtype
rm $FILE_DIR/$currtype
done

Success
