We don't know what your procedure mv_refresh_job is doing.
Why you don't simply call dbms_mview.refresh directly ?
BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
    JOB_NAME        => 't1_MV_REFRESH',
    JOB_TYPE        => 'PLSQL_BLOCK',
    JOB_ACTION        => 'BEGIN DBMS_MVIEW.REFRESH(''T1MV'', ''F''); END;',
    START_DATE      => SYSTIMESTAMP,
    REPEAT_INTERVAL => 'freq=minutely; bysecond=0;',
    END_DATE        => NULL,
    ENABLED         => TRUE,
    COMMENTS        => 'Refreshes Materialized Views on a Scheduled Basis');
END;
or you can use refresh clause when creating MV.
When you call dbms_mview.refresh('T1MV','F'); from SQL*Plus what's the result ?
