Background:

Generally we use ctrl+c to quit any task in windows command prompt or ctrl+z in Unix flavors. For oracle data pump exports/imports this is not the case when you type any of them, ctrl+c or ctrl+z actually pause the job and closing the command or shell window doesn’t quit the oracle data pump job rather it is running at background. so how to quit the background export or import data pump job?

Workaround:

1. First we need to identify the export/import job we need to kill
2. Use the KILL_JOB command in export/import prompt to kill the specified job.

Operation:

1. Query the DBA_DATAPUMP_JOBS will let us know information about the export/import dumps jobs in the database. Select the job you want to kill from the running job/s.

   SELECT job_name, operation, state FROM DBA_DATAPUMP_JOBS;

2. Open the command/shell prompt and login to database data pump export/import session and ATTACH your current session to the specified job needs to kill. Suppose the job name is SYS_EXPORT_SCHEMA_01

EXPDP SYSTEM/password@Oracleinstance ATTACH=SYS_EXPORT_SCHEMA_01

Now type the KILL_JOB, will prompt you whether you are sure to kill the job, type Yes and then Enter.

Database will kill the job, after sometime re-execute the above query to see the job actually killed.

A typical session for example:
C:\Users\Administrator>expdp system/password attach=SYS_EXPORT_SCHEMA_04
