Hello Upendra,
I understand. But you missed to provide the first query i.e.
set line 120 pages 100
col severity for a15
col message for a70
col timestamp for a20
select severity,error_code,to_char(timestamp,'DD-MON-YYYY HH24:MI:SS')
"timestamp" , message from v$dataguard_status where dest_id=3;
Thanks.

Hi Nassyam,
I believe the configuration is correct, otherwise I wouldn't be receiving
any archivelogs at the destination. The DB_unique_name is set to "SID_DR"
in the data guard site and there is a corresponding TNS entry in the PROD
site (with the same name) pointing to the data guard site.
The issue is I am receiving SOME logs but not ALL the archivelogs at the
data guard site.
As I pasted the output of the archivelogs in my earlier message, see the
sequence numbers are all over the place..
This is from ASM:

When the logapply hits the point where the archivelog is missing it is
copying from Prod, which is slowing the log apply significantly.
From alert.log at data guard:
Media Recovery Waiting for thread 1 sequence 434987 (in transit)
Here is the output of the query you sent (taken from Prod):
ID STATUS DB_MODE TYPE RECOVERY_MODE

Hello Upendra,
If the configuration is perfect then the redo/archive should receive on
remote destinations.
If you see below, you have mentioned service=SID_DR, can you confirm you
have used the Oracle net service which points to the related standby
database? and what about db_unique_name also you have mentioned SID_DR, it
should be the unique name but not SID, so it depends on configuration
however what the db_unique_name,sid, service configured.
"*service="SID_DR", LGWR ASYNC NOAFFIRM delay=0 optional
compression=disable max_failure=0 max_connections=1 reopen=15*
* db_unique_name="SID_DR"
net_timeout=30, valid_for=(all_logfiles,primary_role)*"
Can you send output of this below query? Run them from primary.
set line 120 pages 100
col severity for a15
col message for a70
col timestamp for a20
select severity,error_code,to_char(timestamp,'DD-MON-YYYY HH24:MI:SS')
"timestamp" , message from v$dataguard_status where dest_id=3;
select ds.dest_id id
, ad.status
, ds.database_mode db_mode
, ad.archiver type
, ds.recovery_mode
, ds.protection_mode
, ds.standby_logfile_count "SRLs"
, ds.standby_logfile_active active
, ds.archived_seq#
from v$archive_dest_status ds
, v$archive_dest ad
where ds.dest_id = ad.dest_id
and ad.status != 'INACTIVE'
order by
ds.dest_id;
Thanks.

Hello everyone -
Happy new year!
Oracle RAC 11.2.0.3
OEL 5.x
I have an environment in which the primary is shipping logs to a local
standby and a remote dataguard database.
What I am seeing is that, somehow not all the archivelogs are being
shipped to the remote site. At the time of log apply these logs are being
transmitted over.
Here is an example on how the redologs appear in the remote site:
512 1860501 952576512 954204160
thread_1_seq_434986.5778.900455621

512 1438234 736375808 738197504
thread_1_seq_435024.11250.900460605
Similar gaps for thread_2 as well..
Here is the configuration of the log_archive_dest_3 on primary for the
remote site:
*service="SID_DR", LGWR ASYNC NOAFFIRM delay=0 optional
compression=disable max_failure=0 max_connections=1
reopen=15
db_unique_name="SID_DR" net_timeout=30,
valid_for=(all_logfiles,primary_role)*
I do not see any errors for the redo transport in the alert log on the
primary site or on the remote DG site.
Any thoughts on how should I troubleshoot this? Are there any known bugs
around this?
Your help is appreciated.
Thanks
-Upendra
