pscbo_stats question regarding error message in pscbo_log

We are upgrading HR Peoplesoft to 9.1 PT 8.54. We had pscbo_stats v1, in the database originally from the earlier HR Peoplesoft 9.0 database.

We ran the new v3 pscbo.sql. When we run the pscbo stats command to generate stats ( exec pscbo_stats.gather_schema_stats ) we get error message in the pscbo_log:

  The error is: Please execute: EXEC DBMS_AUTO_TASK_ADMIN.DISABLE('auto optimizer stats collection', NULL, NULL);'

I do not see the above command in the documentation!

We have done the following step in the implementation guide:

SET SERVEROUT ON TRIMS ON LINES 1000;
