question: How to create a shell script to run export/import utilities?
Here is a sample script to run the import/export utilities of datapump. Modify the script to set environment variables like ORACLE_HOME, ORACLE_SID, DUMPDIR, etc according to your choice and environment.
The script:
# SCRIPT
# ---------
#
# Set environment variables for ORACLE_HOME, ORACLE_SID,
# and DUMPDIR -- in case of datapump --, as well as PATH if needed.
#
#
trap '' 1 # to use nohup in a shell script
# Set these to appropriate values if needed:
#
# ORACLE_HOME=
# ORACLE_SID=
# DUMPDIR=
# Customize PATH if needed
#
# PATH=/bin:/usr/bin:${ORACLE_HOME}/bin:/usr/local/bin:/usr/lbin
# export ORACLE_HOME ORACLE_SID PATH
echo "Exporting $ORACLE_SID database. start `date`"
#
expdp system/password dumpfile=scott.dmp directory=DUMPDIR schemas=scott logfile=scott.log
#
echo "Export of $ORACLE_SID database completed at `date`"
# End of Script
Running the script
If you save the script as exp_comp.sh, type the following command at the Unix prompt to run it:
# ./exp_comp.sh
Note: Edit the above script to use it for your specific exports or imports (like full, schema, table, TTS).
In case of traditional export/imp (exp/imp), the above command may be something like:
$ exp system/manager file=scott.dmp owner=scott log=scott.log
