Oracle... Script: Redo log

Shell scripting... Script: Debug shell program

A User Agent, like a web browser, uses HTTP to request a HTML document

In programming the danger of exploring the small details of coding is that you get obsessed with every line of code you write, thereby greatly reducing productivity.
In general, is not worth obsessing over code.
On the other hand you should code with deliberation and intent. Steven Feurstein Oracle Magazine July /August 2004

Shell scripting

Home >Shell scripting > Shell script automating oracle data pump schema export

Stampa  Stampa

Oracle 10g Data Pump utility is revolutionary. It allows write and scheduling parallel export server side quickly and handy.
Sometimes, in my test environment I still use shell scripts as this one to execute export routines even with Data Pump. Sometimes, I use a slight different script that takes advantage of parallel export and compress files on backgrounds.

  • export using data pump schemas defined in array in single files
  • name file "schema" + "yyyy-dd-mm".dmp
  • compress the dump file
  • makes the compressed files readable and executable
  • system account
  • privilege to execute shell program
# file
# tested on SunOS 5.10
declare -a vschema
# set the array with the name of schemas to export

export vdpdir=replat_dump
read -s psw
while [ "$i" -lt "${#vschema[*]}" ]
export vdumpfile=${vschema[$i]}_`date +%Y_%m_%d`.dmp
export vlogfile=${vschema[$i]}_`date +%Y_%m_%d`.log
echo "... EXPORT SCHEMA: ${vschema[$i]} IN FILE $vdumpfile"
expdp system/$psw PARALLEL=4 dumpfile=$vdumpfile schemas=${vschema[$i]} logfile=$vlogfile directory=$vdpdir
echo "... FILE COMPRESSION $vdumpfile"
compress $vdumpfile
echo "... FILE POLICIES $vdumpfile"
echo $vdumpfile
chmod a=xr $vdumpfile
let i+=1
