Dataguard logs not applied

Question

Hi,
We have dataguard on Oracle 10g. The logs are shipped from primary to physical stand by but when I look at "Last Applied Log" under EM on the primary db, I see 0. The logs are shipping but not applied to physical stand by.
I restarted the standby to mount stage.
I can tnsping both the database from other servers
***** on primary *****
SELECT name, value FROM gv$parameter WHERE name = 'log_archive_dest_state_1';
NAME

log_archive_dest_state_1
enable
SELECT name, value FROM gv$parameter WHERE name = 'log_archive_dest_state_2';
NAME
VALUE
log_archive_dest_state_2
ENABLE
SELECT name, value FROM gv$parameter WHERE name = 'standby_archive_dest';

select status, error from v$archive_dest where dest_id=2;

SELECT dest_id, valid_type, valid_role, valid_now FROM gv$archive_dest;
DEST_ID VALID_TYPE VALID_ROLE VALID_NOW

***** on physical stand by *****

PROTECTION_MODE PROTECTION_LEVEL DATABASE_ROLE
MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE PHYSICAL STANDBY
SELECT MAX(SEQUENCE#), THREAD# FROM V$ARCHIVED_LOG GROUP BY THREAD#;
MAX(SEQUENCE#) THREAD#

Can anyone advise what can I check and how can I get the logs to apply on the standy by. The stand by is in mount stage. Thanks

The alert log for primary does not show any errors:
LNS: Standby redo logfile selected for thread 1 sequence 4520 for destination LOG_ARCHIVE_DEST_2
This is in the alert log for standby
Primary database is in MAXIMUM PERFORMANCE mode
RFS[11]: Successfully opened standby log 5: '/u02/oradata/prd1/stby_redo_g5_m1.dbf'
On standby I have the MRP process running:
$ ps -ef|grep mrp
oracle 10957 1 0 15:26:48 ? 0:01 ora_mrp0_prd1
SELECT RECOVERY_MODE FROM V$ARCHIVE_DEST_STATUS WHERE DEST_ID=2 ;
RECOVERY_MODE
MANAGED REAL TIME APPLY
This is from v$dataguard_status
Remote File Server Warning 0 167 0 NO 20-DEC-07
RFS[11]: Successfully opened standby log 5: '/u02/oradata/prd1/stby_redo_g5_m1.dbf'
should I try this as first suggested ?
