Question : OEM Job

Hi,
How would i Create OEM job to shrink data files?

Answer : OEM Job

using OEM, of course and writing a procedure in the SYS schema that does the job.

The experience shows that it is easier to schedule the JOB using DBMS_JOB package or the new DBMS_SCHEDULER (10g) package. OEM do not works reliable, but you can give a try.
