3) Verify the database post steps

set pagesize 1000;
set linesize 1000;
col STATUS for a10;
col ACTION_TIME format a30;
col DESCRIPTION format a55;
select PATCH_ID,status,ACTION_TIME,DESCRIPTION from dba_registry_sqlpatch;

Here on node2 auto patch command is used so database patch is done automatically
