Data Guard Related Problem

We are using oracle 9.2, i am facing a problem in the dataguard is that i want to know whether the log have been applied or not.....below are the outputs....
we are using manual data guard......
SELECT THREAD#, SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG;
no rows selectedwhen i fire the above query it is not showing any result......
pls suggest me ..
SQL> show parameter stand
NAME                                 TYPE        VALUE
standby_archive_dest                 string      /arch/log
standby_file_management              string      MANUAL
SQL> SELECT THREAD#, MAX(SEQUENCE#) AS "LAST_APPLIED_LOG"
2 FROM V$LOG_HISTORY

   THREAD# LAST_APPLIED_LOG
         1             1724
         2             1537
SELECT THREAD#, SEQUENCE#, APPLIED FROM V$ARCHIVED_LOG;
no rows selected

we are using a manual standby database.......
SQL> select DATABASE_ROLE, SWITCHOVER_STATUS,DATAGUARD_BROKER from v$database;
DATABASE_ROLE    SWITCHOVER_STATUS DATAGUAR
PHYSICAL STANDBY SESSIONS ACTIVE    DISABLED
SQL> show parameter stand
NAME                                 TYPE        VALUE
standby_file_management              string      MANUALso pls suggest me how would i know whether the archives have been applied or not.....
although i have posted the query which i was using for the same
and one more thing i am getting an error in alert log file also...

Data guard related OS processes in Primary and Standby servers

Database version : 11.2.0.3
Operating System : RHEL 5.8
Type: Physical Standby
++++++++++++++++++++++++++++In a typical Linux server hosting a Physical standby DB, the data guard related OS processes that appear in ps output
are like below. One mrp for each standby DB.
ps -ef |grep mrp
oracle 9380     1   0   May 21 ?          57:33 ora_mrp0_STRYKER_DG
oracle 18874     1   0   May 23 ?          33:45 ora_mrp0_FLPSA
oracle 18992 18837   0 23:39:39 pts/3       0:00 grep mrpSimilarly ,In a typical Linux server hosting a Primary DB what are the data guard related OS processes that appear in ps output ? Will LNS process appear in ps output ? Any other processes ?

Similarly ,In a typical Linux server hosting a Primary DB what are the data guard related OS processes that appear in ps output ? Will LNS process appear in ps output ? Not exactly but it appears has different name, on your primary try below commands
SQL> select pid from v$managed_standby where process='LNS';
$ps -ef|grep <pid value>
hope this helps, on standby you can use same procedure to find the RFS OS process

Data Guard Summary problem using Grid Control.

I setup data guard using Grid Control and after completion, the console of the standby database shows: "Unable to determine Data Guard information." under the Data Guard Summary section. The primary database is not showing the standby. I'm using Red Hat Linux Server 5.7 (64bit) and Oracle 10.2.0.5. This is a standalone (no RAC or ASM involved). When I run show configuration, the following comes up:
DGMGRL> SHOW CONFIGURATION;
Configuration
Name: PRODDB_ghph@ora01
Enabled: YES
Protection Mode: MaxPerformance
Fast-Start Failover: DISABLED
Databases:
ghph - Primary database
gsbh - Physical standby database (disabled)
Current status for "PRODDB_ghph@ora01":
SUCCESS
I tried searching online and metalink but nothing. Any help in solving this problem would be appreciated. TIA

Can you confirm that only archive sequence * 58673* is missing or any more? If you have less number of archives are missing then see how the parameters you configured. like FAL_SERVER, LOG_ARCHIVE_CONFIG, LOG_ARCHIVE_DEST_n so on.
Check below command and see any errors with remote destinations

If the archives are missing so many and you do not have backup, then certainly you have to choose incremental roll forward to synchronize the primary database, then only you can see the configuration status of Broker as valid. You can refer this article to perform incremental roll forward http://www.oracle-ckpt.com/rman-incremental-backups-to-roll-forward-a-physical-standby-database-2/

Data guard performance problem (rac to single instance)

i have a table it has GPS data, and gps table has too many data, 5 millions,
iam using RAC (2 nodes 11gr2). standby database is single instance data guard,
single instance database (standby)'s hardware cpu is lower than RAC machines. rac nodes have (15k) disks, standby has (7200rpm),
so i dont want to use GPS tables on data guard system, i dont want to run GPS table's DML commands (delete, insert), i think it may increase performance,
is it posible? what is your advise?
any feedback makes me happy,
best regards

it's not possible with data guard, but you can use streams or golgengate for this purpose. Have a look at dataguard performance tuning guide. Maybe there is something you can fix on the configuration to be faster.

Data Guard and FLASHBACK

RDBMS Version : 11.2
Platform : Solaris 10
I've joined this new company. On Data guard related design documents I keep seeing FLASHBACK related stuff. Things like extra disk space requirements for setting up FLASHBACK DATABASE. What is this all about ?
What has Flashback got to do with Data guard setups ? I just need a high level overview.
Regarding extra disk space requirements for setting up FLASHBACK DATABASE : Is this at Primary of Standby site ?

Hello;
Flashback is not required for Data Guard. However if you ever need to do a failover it may play an important role.
During a failover it is common to use flashback to recover the old primary to a point where it can become the new standby.
Flashback may also be used with DELAY on a Standby, and with Snapshot database.
I would enable it on both the primary and standby databases.
For additional information see :
Oracle® Data Guard Concepts and Administration 11g Release 2 (11.2) E10700-02
And these sections
7.2.2.1 Using Flashback Database as an Alternative to Setting a Time Delay
8.4 Using Flashback Database After a Role Transition
8.4.2 Using Flashback Database After a Failover
13.2 Converting a Failed Primary Into a Standby Database Using Flashback Database

Exadata to non Exadata Data Guard

I was wondering if I can make a configuration of an Exadata RAC to non Exadata single node Data Guard.
I made some RAC to single node data guards without problem, but I wonder if it is posible with exadata since
exadata is intel based, maybe I can save some thousands with a DR site with a non exadata hardware.
FJA

In theory, it should work. However, I suggest that you ask your Exadata Support. Or raise a query in the Exadata forum space.
Just realised that if you use Exadata specific features (EHCC -- Hybrid Columnar Compression), you'd have difficulties.

Problem with logminer in Data Guard configuration

Hi all,
I experience strange problem with applying of the logs in DataGuard configuration on the logical standby database side.
I've set up the configuration step by step as it is described in documentation (Oracle Data Guard Concepts and Administration, chapter 4).
Everything went fine until I issued
ALTER DATABASE START LOGICAL STANDBY APPLY;
I saw that log applying process was started by checking the output of
SELECT NAME, VALUE FROM V$LOGSTDBY_STATS WHERE NAME = 'coordinator state';
and
SELECT TYPE, HIGH_SCN, STATUS FROM V$LOGSTDBY;
but in few minutes it stoped and quering DBA_LOGSTDBY_EVENTS I saw the following records:
ORA-16111: log mining and apply setting up
ORA-01332: internal Logminer Dictionary error
Alert log says the following:
LOGSTDBY event: ORA-01332: internal Logminer Dictionary error
Wed Jan 21 16:57:57 2004
Errors in file /opt/oracle/admin/whouse/bdump/whouse_lsp0_5817.trc:
ORA-01332: internal Logminer Dictionary error
Here is the end of the whouse_lsp0_5817.trc
error 1332 detected in background process
OPIRIP: Uncaught error 447. Error stack:
ORA-00447: fatal error in background process
ORA-01332: internal Logminer Dictionary error
But the most useful info I found in one more trace file (whouse_p001_5821.trc):
krvxmrs: Leaving by exception: 604
ORA-00604: error occurred at recursive SQL level 1
ORA-01031: insufficient privileges
ORA-06512: at "SYS.LOGMNR_KRVRDREPDICT3", line 68
ORA-06512: at line 1
Seems that somewhere the correct privileges were not given or smth like this. By the way I was doing all the operations under SYS account (as SYSDBA).
Could smb give me a clue where could be my mistake or what was done in the wrong way?
Thank you in advance.

I have one problem with Data Guard. My archive log files are not applied.

I have one problem with Data Guard. My archive log files are not applied. However I have received all archive log files to my physical Standby db
I have created a Physical Standby database on Oracle 10gR2 (Windows XP professional). Primary database is on another computer.
In Enterprise Manager on Primary database it looks ok. I get the following message Data Guard status Normal
But as I wrote above the archive log files are not applied
After I created the Physical Standby database, I have also done:
1. I connected to the Physical Standby database instance.
CONNECT SYS/SYS@luda AS SYSDBA
2. I started the Oracle instance at the Physical Standby database without mounting the database.
STARTUP NOMOUNT PFILE=C:\oracle\product\10.2.0\db_1\database\initluda.ora
3. I mounted the Physical Standby database:
ALTER DATABASE MOUNT STANDBY DATABASE
4. I started redo apply on Physical Standby database
alter database recover managed standby database disconnect from session
5. I switched the log files on Physical Standby database
alter system switch logfile
6. I verified the redo data was received and archived on Physical Standby database

Hi,
After several tries my redo logs are applied now. I think in my case it had to do with the tnsnames.ora. At this moment I have both database in both tnsnames.ora files using the SID and not the SERVICE_NAME.
Now I want to use DGMGRL. Adding a configuration and a stand-by database is working fine, but when I try to enable the configuration DGMGRL gives no feedback and it looks like it is hanging. The log, although says that it succeeded.
In another session 'show configuration' results in the following, confirming that the enable succeeded.
DGMGRL> show configuration
Configuration
Name: avhtest
Enabled: YES
Protection Mode: MaxPerformance
Fast-Start Failover: DISABLED
Databases:
avhtest - Primary database
avhtestls53 - Physical standby database
Current status for "avhtest":
Warning: ORA-16610: command 'ENABLE CONFIGURATION' in progress
It there anybody that experienced the same problem and/or knows the solution to this?
With kind regards,
Martin Schaap

DB link problem between active Data Guard and report application database

My database version in 11.2.0.2.0 and OS is Oracle Solaris 10 9/10.
I am facing a problem in my Active data guard Database for reporting purpose. Active Data guard information is as below.
SQL> select name, database_role, open_mode from v$database;
NAME DATABASE_ROLE OPEN_MODE
ORCL PHYSICAL STANDBY READ ONLY WITH APPLY
Problem detail is below
I have created a db link (Name: DATADB_LINK) between active data guard and report application database for reporting purpose.
SQL> create database link DATADB_LINK connect to HR identified by hr using 'DRFUNPD';
Database link created.
But when I run a query using db link from my report application database I got this below error.
ORA-01555: snapshot too old: rollback segment number 10 with name "_SYSSMU10_4261549777$" too small
ORA-02063: preceding line from DATADB_LINK
Then I check Active Data Guard database alart log file and get below error
ORA-01555 caused by SQL statement below (SQL ID: 11yj3pucjguc8, Query Duration=1 sec, SCN: 0x0000.07c708c3):SELECT "A2"."BUSINESS_TRANSACTION_REFERENCE","A2"."BUSINESS_TRANSACTION_CODE",MAX(CASE "A1"."TRANS_DATA_KEY" WHEN 'feature' THEN "A1"."TRANS_DATA_VALUE" END ),MAX(CASE "A1"."TRANS_DATA_KEY" WHEN 'otherFeature' THEN "A1"."TRANS_DATA_VALUE" END )
But the interesting point if I run the report query directly in Active Data Guard database, I never got error.
So is it a problem of DB link between active Data Guard and other database?

Oracle RAC / Logical Data Guard causing network problems on VMware

We have VMWare 5.0 cluster across the 12 blades (6 per chassis) running a mixture of Red Hat and Windows 2008 R2 vms. The Red Hat boxes are two times two node Oracle RAC (primary and secondary), also apache web servers and jboss application servers. The Windows servers are for AV/DC/Management/Monitoring.
The problem is that intermittent network connectivity to random Windows and Red Hat boxes occur when the Oracle RAC builds up archive logs and then ships / applies them to the secondary nodes, between ESX nodes either on different blades in the same chassis or across the chassis and even when all RAC nodes are on the same ESX host.
We are using NFS, Oracle 11g and Red Hat 6.2.
Sorry if this info is a bit vague, im not an Oracle expert! :-)
thanks,
Dave

Hi,
1.) The calculation for Standby RedoLogs is:
(Max Number of Logfiles per thread (Instance) +1) * Max Number of Threads (Instances))
So if you have 4 Redo Log Groups on your primary (which is 2 Redo Log Groups per Instance), then it ends up:
(2 +1) * 2 = 6
So actually you will only need 6 standby redo logs, not 8. But 2 more don't harm.
Your primary will need exactly the same number (6 or in your case 8). Which will be 3 per thread/instance or in your case 4.
2.) The SID List in the listener.ora is a listing of SIDs the Listener is listening on. It is not the listener name.
Hence it is not "lsnrctl guard_dgmgrl start" but only "lsnrctl LISTENER start", whereas the LISTENER is the default and "lsnrctl start" would be sufficient.
However since this is grid infrastructure with the listener running out of ASM home, be sure to have set your environment to GI Home not to DB_HOME for the listener.ora entries, but to DB_HOME for the tnsnames.ora entries necessary for data guard.
And since listener is running under clusterware you should use "srvctl stop listener" and start.
Last but not least the SID entries for dataguard have to use DGMGRL not dgmgrl.
3.) Here is the whitepaper you are looking for:
www.oracle.com/goto/maa
Also for client failover best practices.
(Here the direct link to the RAC whitepaper):
http://www.oracle.com/technetwork/database/features/availability/maa-wp-10g-racprimarysingleinstance-131970.pdf
However since this is 10g you should combine this with the 11g RAC standy paper (e.g. SCAN Listener setup).

The answer depends on the protection level are you using, If you are using maximum performance or maximum availability you can use 6 groups with 1 member in each group, in case of redo corruption the primary database will continue to function properly and you will have time to fix the corrupted redo. If you are planning to use maximum protection I would recommend at least 2 members in each group, to avoid primary crush in case of standby redo corruption.

Problem with data guard Creating a Physical Standby Database turorial

There is a tutorial of Creating a data guard Physical Standby Database:
http://www.oracle.com/technology/obe/11gr1_db/ha/dataguard/physstby/physstdby.htm
I tried to install it on two servers. One for primary database second for physical standby.
I have error on C. Creating the standby database over the network, action #6:
"On the standby system, set the ORACLE_SID environment variable to your <physical standby SID> (i.e. orclsby1) and start the instance in NOMOUNT mode with the text initialization parameter file."
When I try to connect to idle instance there is an error pops up:
C:\>sqlplus / as sysdba
SQL*Plus: Release 11.1.0.7.0 - Production on Thu May 21 16:28:10 2009

ERROR:
ORA-12560: TNS:protocol adapter error
I'v checked listener and it is runned. There is no service for database because there is no database yet.
The question is did some one installed data guard configuration using this tutorial? Is there any errors in it? What should I do to finish this installation?

On Windhose for every instance a service must have been created using the oradim command.
Oracle tutorials are usually Unix-centric, as Windhose is an odd man out, so they don't discuss that bit.
'Kindly do the needful' and create the service prior to starting the instance in nomount mode
Hint: oradim is documented and has a help=y clause.
IIRC there is an option in database control (in the maintenance part) which automates everything.

Data guard role transition problem

Hi,
I am trying to do a switchover using the data guard broker cli and get the following error:
DGMGRL> switchover to "TGDRDB01"
Performing switchover NOW. Please wait...
Error: ORA-16775: Target standby in switchover operation has missing redo logs.
Failed.
Can not proceed to switchover. Primary is still "TGDB01".
The drc log file shows a bit more info:
DG 2005-12-01-17:17:43 2000000 3 574466141 DMON: chief lock convert for switchover

DG 2005-12-01-17:18:17 2000000 3 574466141 Operation CTL_SWITCH cancelled during phase 0, error = ORA-16775
What i don't understand is the bit about 338 redo logs missing becuase the output from "archive log list" on both databases is as follows:
Primary
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /home/oracle/admin/TGPROD/archive
Oldest online log sequence 3091
Next log sequence to archive 3093
Current log sequence 3093
Standby
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /home/oracle/admin/TGPROD/archive
Oldest online log sequence 3091
Next log sequence to archive 0
Current log sequence 3093
Any help will be gratefully recieved as I'm stumped! Found a note for the original oracle error on here that said try switching logfiles a couple of times then trying again - which suffices to say didn't work. I don't understand where it gets 338 missing redo logs from!?!?
Oh and oracle version is 10.1.0.3....
thanks in advance.
regards,
Mark

Yes, it'll be waiting for these archive till he gets them.
If you see the files at system level, then cancel the MRP and apply them manually. If those files are missiong, then stop MRP and propagate hot backups from your primary db to the standby db, then reactivate the MRP. This will resync the databases.
Regards,
Yoann.
