How to Run Expdp Impdp Jobs in Background

Step 1: Create export or import parameter file

$ cat exp.par

userid=sthomas/tiger

job_name=tab_export

directory=EXP_DIR

dumpfile=TST_table_exp.dmp

logfile=TST_tab_exp.log

REUSE_DUMPFILES=y

tables=sox.PROFILE,sox.PROFIL_ACC_TYPE,sox.PURCHASE_STEP,sox.RULE,sox.SUB,sox.SUB_TABLE,sox.TIME_PERIOD

Step 2: Create a shell script which calls the expdp in nohup and change the permission to executable.

$ cat export.sh

nohup expdp parfile=/home/oracle/st/exp.par &

 

$ chmod 744 export.sh

 

Step 3: run the shell script in nohup. This will release the prompt immediately and there will not be any running job in the prompt. You can see the datapump job running in DBA_DATAPUMP_JOBS view.
