Archived log missed in standby database

Hi,
OS; Windows 2003 server
Oracle: 10.2.0.4
Data Guard: Max Performance
Dataguard missed some of the archivelog files and but latest log files are applying. standby database is not in sync with primary.
SELECT LOCAL.THREAD#, LOCAL.SEQUENCE# FROM (SELECT THREAD#, SEQUENCE# FROM V$ARCHIVED_LOG WHERE DEST_ID=1) LOCAL WHERE LOCAL.SEQUENCE# NOT IN (SELECT SEQUENCE# FROM V$ARCHIVED_LOG WHERE DEST_ID=2 AND THREAD# = LOCAL.THREAD#);
I queried above command and I found some files are missed in standby.
select status, type, database_mode, recovery_mode,protection_mode, srl, synchronization_status,synchronized from V$ARCHIVE_DEST_STATUS where dest_id=2;
STATUS TYPE DATABASE_MODE RECOVERY_MODE PROTECTION_MODE SRL SYNCHRONIZATION_STATUS SYN
VALID PHYSICAL MOUNTED-STANDBY MANAGED MAXIMUM PERFORMANCE NO CHECK CONFIGURATION NO
Anyone can tell me how to apply those missed archive log files.
Thanks in advacne

ERROR at line 1:
ORA-01153: an incompatible media recovery is activeYou need to essentially do the following.
1) Stop managed recovery on the standby.
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;2) Resolve the archive log gap - if you have configured FAL_SERVER and FAL_CLIENT Oracle should do this when you follow step 3 below, as you've manually copied the missed logs you should be OK
3) restart managed recovery using the command shown above.
You can monitor archive log catchup using the alert.log or your original query.

Archive log missing on standby: FAL[client]: Failed to request gap sequence

My current environment is Oracle 10.2.0.4 with ASM 10.2.0.4 on a 2 node RAC in production and a standby that is the same setup. I'm also running on Oracle Linux 5. Almost daily now an archivelog doesnt make it to the standby and oracle doesnt seem to resolve the gap sequence from the primary. If I stop and restart recovery it gets the logfile and continues recovery just fine. I have checked my fal_client and fal_server settings and they look good. The logs after this error do continue to get written to the standby but the standby wont continue recovery until I stop and restart recovery and it fetches this missing log.
The only thing I know thats happening is that the firewall people are disconnecting any connections that are inactive for 60 minutes and recently did an upgrade that they are claiming didnt change anything:) I dont know if this is causing this problem or not. Any thoughts on what might be happening?

It's the network that's messing up; unlikely due to firewall timeout as it waits for 60 minutes and you are switching every 15 minutes. There may be some other network glitch that needs rectified.
In any case - arch file missing/ corrupt / halfway through - FAL setting should have refetched the problematic archive log automatically.
As many had suggested already, the best way to resolve RFS issues I believe is to use real-time apply by configuring standby redo logs. It's very easy to configure it and you can opt for real-time apply even in max-performance mode that you are using right now.
Even though you are maintaining (I guess) 1-1 between primary & standby instances, you can provide both primary instances in fal_server (like fal_server=string1,string2). See if that helps.
lastly, check if you are having simiar issue at other times as well that might be getting rectified automatically as expected.

select message, to_char(timestamp,'dd-mon-rr hh24:mi:ss') time

How to delete archive logs on the standby database....in 9i

Hello,
We are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.
The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.
Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.
thanks,
C.

Check this note.
*Configure RMAN to purge archivelogs after applied on standby [ID 728053.1]*
Still it is on 9i, So you need to schedule RMAN job or Shell script file to delete archives.
Before deleting archives
1) you need to check is all the archives are applied or not
2) then you can remove all the archives completed before 'sysdate-2';
RMAN> delete archvielog all completed before 'sysdate-2';
As per your requirement.

What is default mode? I think you want ask in what mode standby database is apply redo logs.
Standby database can apply received redo only MOUNT mode, (your version is 10g, after 11g can apply open mode with READ ONLY WITH APPLY)
2. Should we Always Start Physical Standby Database to Recover Missing Redo Archive Log?
If Standby database opened mount mode, then database can receive redo.
If you are start Redo Apply then MPR can request from primary for missing redo logs.

Log 8, 9, 10, 11, 12, 13, 14, 15 are missing.It is no missing, you are created standby database, after sequence 15.
As you know , if a sequence redo is not applied, then after is sequenced redo log is cannot apply to standby database.
It means GAP.
There have 43 archived redo log, and your last sequenced archive log received by standby database
and applied.
You can check with following scripts, too
select max(Sequence#) from v$archived_log; -- on primary
select max(Sequence#) from v$archived_log where applied = 'YES'; - on standby Regards

Apply missing log on physical standby database

I already registered the missing log and started the recovery process.
Still...having log on standby that has status ..not applied.

Not much experience doing this, but according to the 9i doc (http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96653/log_apply.htm#1017352), all you need is properly-configured FAL_CLIENT and FAL_SERVER initialization parameters, and things should take care of themselves automatically. Let us know if that doesn't work for you, we might be able to think of something else.

*HOW TO DELETE THE ARCHIVE LOGS ON THE STANDBY*

HOW TO DELETE THE ARCHIVE LOGS ON THE STANDBY
I have set the RMAN CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY; on my physical standby server.
My archivelog files are not deleted on standby.
I have set the CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default on the Primary server.
I've checked the archivelogs with the FRA and they are not beign deleted on the STANDBY. Do I have to do something for the configuation to take effect? Like run a RMAN backup?
I've done a lot ofresearch and i'm getting mixed answers. Please help. Thanks in advanced.

Setting the Policy will not delete the Archive logs on the Standby. ( I found a thread where the Data Guard product manager says "The deletion policy on both sides will do what you want" ). However I still
like to clean them off with RMAN.
I would use RMAN to delete them so that it can use that Policy are you are protected in case of Gap, transport issue etc.
There are many ways to do this. You can simply run RMAN and have it clean out the Archive.
Example :
#!/bin/bash
# Name: db_rman_arch_standby.sh
# Purpose: Database rman backup
# Usage : db_rman_arch_standby <DBNAME>
if [ "$1" ]
then DBNAME=$1
else
echo "basename $0 : Syntax error : use . db_rman_full <DBNAME> "
exit 1
fi
. /u01/app/oracle/dba_tool/env/${DBNAME}.env
echo ${DBNAME}
MAILHEADER="Archive_cleanup_on_STANDBY_${DBNAME}"
echo "Starting RMAN..."
$ORACLE_HOME/bin/rman target / catalog <user>/<password>@<catalog> << EOF
delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-8';
exit
EOF
echo `date`
echo
echo 'End of archive cleanup on STANDBY'
mailx -s ${MAILHEADER} $MAILTO < /tmp/rmandbarchstandby.out

How: Script archive log transfer to standby db

Hi,
I’m implementing disaster recovery right now. For some special reason, the only option for me is to implement non-managed standby (manual recovery) database.
The following is what I’m trying to do using shell script:
1.     Compress archive logs and copy them from Primary site to Standby site every hour. ( I have a very low network )
2.     Decompress archive logs at standby site
3.     Check if there are missed archive logs. If no, then do the manual recovery
Did I miss something above? And I’m not skill in to build shell scripts, is there any sample scripts I can follow? Thanks.

Hi,
Take a look at data guard packages. There is a package just for this purpose: Bipul Kumar notes:
http://www.dba-oracle.com/t_oracledataguard_174_unskip_table_.htm
"the time lag between the log transfer and the log apply service can be built using the DELAY attribute of the log_archive_dest_n initialization parameter on the primary database. This delay timer starts when the archived log is completely transferred to the standby site. The default value of the DELAY attribute is 30 minutes, but this value can be overridden as shown in the following example:
LOG_ARCHIVE_DEST_3=’SERVICE=logdbstdby DELAY=60’;"
1. Compress archive logs and copy them from Primary site to Standby site every hour.Me, I use tar (or compress) and rcp, but I don't know the details of your environment. Jon Emmons has some good notes:
http://www.lifeaftercoffee.com/2006/12/05/archiving-directories-and-files-with-tar/
2. Decompress archive logs at standby siteSee the man pages for uncompress. I do it through a named pipe to simplify the process:
http://www.dba-oracle.com/linux/conditional_statements.htm
3. Check if there are missed archive logs.I keep my standby data in recovery mode, and as soon as the incoming logs are uncompressed, they are applied automatically.
Again, if you don't feel comfortable writing your own, consider using the data guard packages.
Hope this helps. . .

BRARCHIVE backup for high volume offline redo log files on Standby Database

Hi All,
We are through with all of Standby database activity, also started applying the offline redo log files on the Standby site.
The throughput is not utilizing the actual available bandwith.
So we are not able to copy the offline redo files on time, as the offline redo files are piling up on the Production side.
My query is how we can parallely copy the offline redo log files on the DR site (ie. 4-5 redo files at a time).
Kindly guide for the same.
Regards,
Shaibaz

hi,
I have one doubt.
On other server (r3qas) the Umask settings are as followed
User     UMASK value
<sid>adm          077
ora<SID>           077
root                   077
Running SAP System :   SAP R3 4.6C
Running DBMS          : Oracle 9.0
Operating System      :- HP_UX
On this system The new offline redo log files are created with 600 permissions. There is not a problem here, while taking the backup. I checked last "r3qas-archive" backups. There, i have not found any single error related to permissions, or any others (something like, Cannot open /oracle/RQ1/../.........dbf).
If everything is working fine, with this umask setting on this server, then, what's going wrong with the BW Quality server, which have the same umask settings (also others) for all the concerned users, as mentioned above.

Archive log miss : How to restart capture

Hi Gurus,
I configured hotlog CDC distributed on 10.2.0.4 Databases.
I make a mistake: in my source Db I have deleted an Archive log,
and now the state of Capture process in V_$STREAM_CAPTURE is "WAITING FOR REDO: LAST SCN MINED 930696".
Now I'd like to restart the capture process from the next archive (just after the missed archive)
How is it possible?
tnk Fabio

I'm sorry to tell you that, but it's not possible. (Just as it's not possible to recover database with missing logs...)
You will have to recreate the capture process and to re-instantiate the replicated tables.
Regards,

Archive apply issue for standby database in Standard Edition.

We have setup standby database in Oracle standard edition. the archive log cannot be send by oracle automatically. So we manually send the archive over. But do not see the database apply the archive log file. What could be wrong and where should we check on it?
We also used following when finishing the standby DB after running "recover standby database;" for a few archive log file:
alter database recover managed standby database disconnect from session;
======================================================================================
This is the status:

MOUNTED 495550636 ENABLED 1.2201E+13 SESSIONS ACTIVE PHYSICAL STANDBY

The DB version is 10.2.0.5
I can do this to apply at standby DB:
SQL> set autorecovery on
SQL> recover standby database;
Then I tried to run this to leave the session:
alter database recover managed standby database disconnect from session;
Do not seen any apply.

Archive log generation in standby

Dear all,
DB: 11.1.0.7
We are configuring physical standby for our production system.we have the same file
system and configuration for both the servers.. now primary archive
destination is d:/arch and the standby server also have d:/arch .Now
archive logs are properly logged into the standby and the data is
intact . the problem we have archive log generation proper in the
primary arch destionation. but no archive logs are getting
generated in the standby archive location. but archive logs are being
applied to the standby database ?
is this normal ?..in standby archive logs will not be generated ?
Please guide
Kai

There are no standby logs should be generated on standby side. Why do you think it should. If you are talking about parameter standby_archive_dest then, if you set this parameter oracle will copy applied log to this directory, not create new one.
in 11g oracle recomended to not use this parameter. Instead oracle recomended to set log_archive_dest_1 and log_archive_dest_3 similar to this:
ALTER SYSTEM SET log_archive_dest_1 = 'location="USE_DB_RECOVERY_FILE_DEST", valid_for=(ALL_LOGFILES,ALL_ROLES)'
ALTER SYSTEM SET log_archive_dest_3 = 'SERVICE=<primary_tns> LGWR ASYNC db_unique_name=<prim_db_unique_name> valid_for=(online_logfile,primary_role)'

Check actual apply log time on standby database after synchronization

Hi All,
I want to check the date and time stamp of applied archived logs on stanby database. How should I check that??
My dataguard link was broken for sometime and meanwhile lot of transactions happened on primary database. Now When the link came up the synchronisation happened within few hours and ultimatly transport and appliy lag became 0. But now I want to check actual time taken for tranporting the logs and applying them on standby database. Is there any way I could do that easily..
Thanks

This script written by Yousef Rifai I found here http://www.dba-village.com/village/dvp_forum.OpenThread?ThreadIdA=34772&DestinationA=RSS might be just what you need (run on standby database):
set ver off
alter session set nls_date_format='dd-mon-yy hh24:mi:ss'
select app_thread, seq_app, tm_applied,
nvl(seq_rcvd,seq_app) seq_rcvd, nvl(tm_rcvd,tm_applied) tm_rcvd
from
(select sequence# seq_app, FIRST_TIME tm_applied, thread# app_thread
from v$archived_log where applied = 'YES'
and (first_time, thread#) in (
select max(FIRST_TIME ), thread#
from v$archived_log where applied = 'YES'
group by thread# )
(select sequence# seq_rcvd, FIRST_TIME tm_rcvd, thread# rcvd_thread
from v$archived_log where applied = 'NO'
and (first_time, thread#) in (
select max(FIRST_TIME ), thread#
from v$archived_log where applied = 'NO'
group by thread# )
where rcvd_thread(+)= app_thread

Manually Apply Archived log to stand by database

Hi all,
I'm using Oracle 10g. So, we need to apply the archived logs of Primary database to stand by database, but this process must be manually.
A "robot" copy the archived logs to destination. I need to get these archived logs from destination and manually apply to stand by database.
How can I do this?
thank you very much!!!!

How can I do this?First stop current recover process as
alter database recover managed standby database cancel;Then transfer all need archive logs from primary to standby side and apply these manually using below command.
recover standby database until cancel
/*this command will ask full path of archive logs
and give these then finally enter "CANCEL" word*/Finally you can continue normal/automatic state using
alter database recover managed standby database ;

Dropping log file in standby database

Please,
I need a help for the following issue:
I'm making a technical documentation on various event that occur on dataguard configuraation, right now I drop a redo log group file on primary database, and when I try to drop the equivalent log group file on standby database I got the following error:
SQL> alter database drop logfile group 3;
alter database drop logfile group 3
ERROR at line 1:
ORA-01156: recovery in progress may need access to files
this is the current state of the redolog file on standby database.
SQL> select group#,members,status from v$log;
GROUP# MEMBERS STATUS
1 3 CLEARING_CURRENT
3 3 CLEARING
2 3 CLEARING
Eventhough I do the following command on standby I also get an error.
SQL> ALTER DATABASE CLEAR LOGFILE GROUP 3;
ALTER DATABASE CLEAR LOGFILE GROUP 3
ERROR at line 1:
ORA-01156: recovery in progress may need access to files
Can someone tell me how to drop on dataguard configuration the redolog file on primary database and their corresponding on standby database
I'm working on 10 release 2, on Windows
Thanks you

Oracle Dataguard Concept and administration release 2,ref b14239: is my source but it doesn't work when trying to drop stanby group or logile member.
For example, if the primary database has 10 online redo log files and the standby
database has 2, and then you switch over to the standby database so that it functions
as the new primary database, the new primary database is forced to archive more
frequently than the original primary database.
Consequently, when you add or drop an online redo log file at the primary site, it is
important that you synchronize the changes in the standby database by following
these steps:
1. If Redo Apply is running, you must cancel Redo Apply before you can change the
log files.
2. If the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO,
change the value to MANUAL.
3. Add or drop an online redo log file:
■ To add an online redo log file, use a SQL statement such as this:
SQL> ALTER DATABASE ADD LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log'
SIZE 100M;
■ To drop an online redo log file, use a SQL statement such as this:
SQL> ALTER DATABASE DROP LOGFILE '/disk1/oracle/oradata/payroll/prmy3.log';
4. Repeat the statement you used in Step 3 on each standby database.
5. Restore the STANDBY_FILE_MANAGEMENT initialization parameter and the Redo Apply options to their original states.
Thank

Capture process issue...archive log missing!!!!!

Hi,
Oracle Streams capture process is alternating between INITIALIZING and DICTIONARY INITIALIZATION state and not proceeding after this state to capture updates made on table.
we have accidentally missing archivelogs and no backup archive logs.
Now I am going to recreate the capture process again.
How I can start the the capture process from new SCN ?
And Waht is the batter way to remove the archive log files from central server, because
SCN used by capture processes?
Thanks,
Faziarain
Edited by: [email protected] on Aug 12, 2009 12:27 AM

Using dbms_Streams_Adm to add a capture, perform also a dbms_capture_adm.build. You will see in v$archived_log at the column dictionary_begin a 'yes', which means that the first_change# of this archivelog is first suitable SCN for starting capture.
'rman' is the prefered way in 10g+ to remove the archives as it is aware of streams constraints. If you can't use rman to purge the archives, then you need to check the min required SCN in your system by script and act accordingly.
Since 10g, I recommend to use rman, but nevertheless, here is the script I made in 9i in the old time were rman was eating the archives needed by Streams with appetite.

        How to use this prg :
                run this file from the crontab, say, each hour.
     example
     1) Delete archive that is sharing common arch disk, when you are at 85% of 2500 mega perform delete half of the files
     whose extention is 'arc' using default affected file (default is -r 2)
     0,30 * * * * /usr/local/bin/watch_arc.sh -e arc -t /arc/POLDEV -s 2500 -p 85 -d -v /var/tmp/watch_arc.POLDEV.log
     2) Delete archive that is sharing common disk with oother DB in /archive, act when 90% of 140G, affect by deleting
     a quater of all files (-r 4) whose extention is 'dbf' but connect before as sysdba in POLDEV db (-i) if they are
     applied (-f is a dataguard option)
     watch_arc.sh -e dbf -t /archive/standby/CITSPRD -s 140000 -p 90 -d -f -i POLDEV -r 4 -v /tmp/watch_arc.POLDEV.log
     3) Delete archive of DB POLDEV when it reaches 75% affect 1/3 third of files, but connect in DB to check if
     logminer do not need this archive (-z). this is usefull in 9iR2 when using Rman as rman do not support delete input
     in connection to Logminer.
