[Reddy, Madhusudana]

Hello All, I have a need to purge the old statistics accumulated by statspack and I am manually using the 'SPPURGE" ( I pass 'losnapid' and 'hisnapid' ) utility , instead I would like have a PL/SQL program which can be automated  through DBMS_JOB . Would somebody help me in this .   Thanks in advance, Madhu
