How to change COMPATIBLE with a physical standby database?

Hello.
The obvious answer is do it on both the primary and the standby at the same time... since the reference manual says : "When using a standby database, this parameter must have the same value on both the primary and standby databases.".
However, I was wondering, I have a 10.2.0.3 DB with compatible=9.2.0.5. What will happen if I leave the parameter to 9.2.0.5 on the standby and just make the change to 10.2.0.3 on the primary? Would I be able to continue to apply the logs on the physical standby? Would I be able to open it ? (I understand that the transport won't probably work anymore and that I won't be able to switchover)
I guess those 2 questions are stupid but I haven't found any clear statement yet.
Please stay tolerant. Thank you.
Gregory
PS: I know what are the alternatives.

So the answer is obviously: We cannot do that. That completely makes sense btw. I tried with 10.2.0.1 to 10.2.0.4 and I got:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 10/22/2008 18:35:55

ORA-00334: archived log: '/u01/app/oracle/oradata/WHITE/redo02.log'
I should have think about it before I asked. That would have meant we could revert the database from 10g to 9i any time... And the bootstrap changes are not stored in the redo log...

Upgrading with a physical standby database in place

Hi all
I am planning to upgrade my database which is 11.2.0.1 (Windows 32 platform) to 11.2.0.3. It has a primary standby database. I only have 1 server for testing the primary database, so I am looking for some help.
I was reading http://docs.oracle.com/cd/B28359_01/server.111/b28294/upgrades.htm#CHDBJAGG and I confuse about step 4 and 5
+4. Install the new release of the Oracle software into a new Oracle home on the physical standby database system, as described in the Oracle Database Upgrade Guide.+
+5. Mount the physical standby database.+
My question is in step 5, when I mount the physical standby database, does it mounted using new Oracle binary or still using the old version? From my understanding what is step 4 doing is to copying files to new home only. Changing the service to use the new oracle binary is done by dbua. I know this when I test upgrading the primary database.
Regards
Stanley.

Hello;
new Oracle binary or the new Oracle home if you will.
So you install the new software on the standby only, all the upgrade SQL gets done on the Primary and then you ENABLE and startup mount on the new oracle home and the standby gets upgraded from the Primary redo.
Its pretty simple ( My exact plan )
1. Disable log shipping from the Primary
2. Shutdown Standby
3. Install 11.2.0.3 on Standby - Just the software
4. Startup Standby in recovery mode - do NOT run r any SQL at the standby
5. Shutdown Primary
6. Install 11.2.0.3 on Primary
7. Run Upgrade SQL or DBUA at Primary
8. Re-enable log shipping
9. Monitor the redo apply from Primary to Standby - this will also upgrade the Standby data dictionary
Make sure your tnsnames and listener files move to the new Oracle home and edit as needed.
Another oracle note is 278641.1

How to apply Oracle patch when physical standby database in place

Dear All,
I want to apply Oracle patchset 8 on 10.2.0.5 when physical standby database in place. What are the steps for Primary site and for standby site.
Thanks in advance
Kamran Laeeq

Hi Kamran,
You will not upgrade or patch the standby database by importing offline redologs. On the contrary, there is a procedure to do this. Please note that you will not transitiate the role from standby to primary or startup the database. You will just startup the database by executing "startup mount" and "startup upgrade", during the upgrade. It means that you will not change database role standby to primary and you will be able to continue to the log shipment after the respective upgrade.
But, it is very important that you should stop the log shipment and apply all the offline redologs, before the upgrade. Technically, you can import offline redologs after the upgrade, by changing "compatibility" parameter in oracle, but regarding to my experiences it may cause some problems after you transitiate the role from standby to primary.
In short;
In order to stop log shipment, at the primary site;
alter system set log_archive_dest_state_2=defer;
In order to import all the offline redologs without a delay, at the standby site;
alter database recover managed standby database cancel;
alter database recover managed standby database nodelay disconnect from session;
I hope that I clarified the issue,
Best regards,
Orkun Gedik

How to apply archivelog with gap on standby database

Please note that I don't have those missing archive on Primary server as well. So How can I apply the remaining archive log which I do have from 20672 onwards.
I hope I am not creating any confusion.
Thx in advance.

Hi Aijaz,
Thx for your answer. But my scenario is bit complex. I have checked my standby database status which is not running in recovery mode. I have tried to find archive_gap which is 0 on standby server. I am copying all archived log from primary to standby thru the script every 2 hour and appying them on standby. After applying, the script is removing all applied log files from primary as well as standby. So it is something like I have archivelog from 1,2,3,7,8,9,10. So 4,5 and 6 archivelog are missing which is required when I am trying to recover standby database. Also note that I want to apply 7,8,9,10. I will loose some data from those missing archive but I have cold back any way. I don't have those missing archivelog files(4,5 and 6) anywhere at all. So how can I recover standby database. I am using standby just for the backup purpose.
I hope my question is clear now.
Thx in advance

How to change the database character set on physical standby database?

Hi,
We have a database with character set WE8ISO8859P1 and migrated the character set to WE8MSWIN1252 using csscan/csalter scripts. This database has a physical standby database setup also and after the migration, the physical standby database is still showing the character set as WE8ISO8859P1. How can I change the characterset on the physical standby? I raised a Service Request with Oracle, and they said that recreating the standby database is the only supported way of changing the char set on the standby database. Is this true?
Thanks,
Sreekanth

Thank you, Robert, for your reply.
The standby is in sync with the primary.

Problem creating physical Standby database with RMAN

Hi All
I am trying to learn oracle dataguard and as part of the process learning creating standby database.
Platform : Sun-Fire-V250 Sparc, Solaris 10
Database Version - Oracle 11R2
I am creating standby database on same server, so directory structure is different.
Following the instructions on Oracle site I managed to create a functional physical standby database. But I am not able to create standby database using RMAN. These are the steps that I followed-
1.Set up all necessary parameters on primary database as done while creating physical standby database manually, eg setting force logging, creating standby logs etc.
2.Edited parameter file on primary database as done while creating manual pysical standby database creation. Some of the changes done are-
On Primary Database:
*.FAL_CLIENT='orcl11020' #Primary database unique name
*.FAL_SERVER='stdby_11' #Standby database unique name
db_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020'
log_file_name_convert='/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11/redo_mem','/<dir>/oradata/orcl11020/redo_mem'
standby_file_management=auto
*.log_archive_config='DG_CONFIG=(orcl11020,stdby_11)'
*.log_archive_dest_1='LOCATION=/<dir>/flash_recovery_area/ORCL11020/archivelog
VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=orcl11020'
*.log_archive_dest_2='SERVICE=stdby_11 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) db_unique_name=stdby_11'
*.LOG_ARCHIVE_DEST_STATE_1='ENABLE'
*.LOG_ARCHIVE_DEST_STATE_2='ENABLE'
*.LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'
*.LOG_ARCHIVE_MAX_PROCESSES=30
Copied same pfile for standby database and modified following-
*.control_files='/<dir>/oradata/stdby_11/stdby_11.ctl','/<dir>/fra_stdby/stdby_11/stdby_11.ctl'
*.db_name='orcl1102'
*.db_unique_name='stdby_11'
*.FAL_CLIENT='stdby_11'
*.FAL_SERVER='orcl11020'
db_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11'
log_file_name_convert='/<dir>/oradata/orcl11020','/<dir>/oradata/stdby_11','/<dir>/oradata/orcl11020/redo_mem','/<dir>/oradata/stdby_11/redo_mem'
standby_file_management=auto
*.log_archive_dest_1='LOCATION=/<dir>/fra_stdby/STDBY_11/archivelog
VALID_FOR=(ALL_LOGFILES,ALL_ROLES) db_unique_name=stdby_11'
*.log_archive_dest_2='SERVICE=orcl11020 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
db_unique_name=orcl11020'
3. Add relevant information in tnsnames.ora and listener.ora files and then restart listener.
3. Created password file with same credential as primary database.
4.Up-to-date RMAN backup of primary database available.
5.Create standby controlfile with rman
While primary database s open (I tried with primary database in mount mode as well)-
$>rman catalog rman/paswd@rman target /
RMAN> BACKUP CURRENT CONTROLFILE FOR STANDBY;
6. Open a new terminal and startup standby database in nomount mode using parameter file created -
$>ORACLE_SID=stdby_11
$>export ORACLE_SID
$>sqlplus / as sysdba
SQL>STARTUP NOMOUNT pfile='<location/initfilename.ora'
SQL>quit
$> rman AUXILIARY / target sys/passwd@orcl11020 catalog rman/passwd@rman
RMAN>DUPLICATE TARGET DATABASE FOR STANDBY DORECOVER;
RMAN finishes without error but archive logs are not being tranported. Looking at the log, following caught my eye-
Error 1017 received logging on to the standby
Check that the primary and standby are using a password file
and remote_login_passwordfile is set to SHARED or EXCLUSIVE,
and that the SYS password is same in the password files.
returning error ORA-16191
FAL[client, ARC2]: Error 16191 connecting to orcl11020 for fetching gap sequence
Errors in file /<>dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
ORA-16191: Primary log shipping client not logged on standby
Errors in file /<dir>/diag/rdbms/stdby_11/stdby_11/trace/stdby_11_arc2_24321.trc:
ORA-16191: Primary log shipping client not logged on standby
So on both primary and standby I confirmed
SQL> show parameter remote_login_passwordfile
NAME TYPE VALUE
remote_login_passwordfile string EXCLUSIVE
To make double sure that password files are same, I shutdown both databases, delete password files and recreated with same credentials.
Password files are called - orapworcl11020 and orapwstdby_11
Can someone guide me where thisngs are going wrong here please.

Not sure if I understood it clearly.
SELECT * FROM V$ARCHIVE_GAP;
returns no rows so there is no gap.
But could you please explain me the result of the previous query. To catch up again, on standby when I check
SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
SEQUENCE# APPLIED
75 NO
74 NO
76 NO
77 NO
I understand that though archive files have been copied across but they are not applied yet.
On primary when I give your query -
SELECT name as STANDBY,SEQUENCE#,applied, completion_time
2 FROM v$archived_log
3 where dest_id=2
4 and sequence# BETWEEN 74 and 80;
I get -
STANDBY SEQUENCE# APPLIED COMPLETIO
stdby_11 74 YES 28-JUN-11
stdby_11 75 YES 28-JUN-11
stdby_11 76 YES 29-JUN-11
stdby_11 77 YES 29-JUN-11
stdby_11 78 YES 29-JUN-11
stdby_11 79 YES 29-JUN-11
stdby_11 80 YES 29-JUN-11
stdby_11 75 NO 07-JUL-11
stdby_11 74 NO 07-JUL-11
stdby_11 76 NO 07-JUL-11
stdby_11 77 NO 07-JUL-11
stdby_11 78 NO 07-JUL-11
I have intentionally given
sequence# BETWEEN 74 and 80
because I know in the current incarnaion of the database, max sequence is 78.
So my understanding is, the rows between 28-29 June are from previous incarnation, correct me if I am wrong
Archive files of the current incarnation, since I successfully created standby database are shipped but yet to be applied - am I right?
Then my final question is, when will these archives be applied to standby database?
I am sorry to ask too many questions but I am just trying to understand how it all works.
Thanks for your help again

How Real Time Apply works while physical standby is open in Read Only mode

Hi,
With Active data guard option, we can open physical standby DB in read only mode, while redo log are being applied. (Real Time Query)
Standby Redo log (SRL) enables Real Time Apply (with "USING CURRENT LOGFILE" clause in recover database command on standby DB)
I am interested to know, how Real Time Query works ?
What is the mechanism with allows us to open physical standby DB in read only mode while redo logs are being applied continuously ?
Regards,
Sujit

Dear user7419391,
That is a new feature in Oracle Database 11g. MRP can use the real time apply in 10g but the concept here is different.
Taken from the following document;
http://www.ascent.co.za/documents/oracle/Oracle%20databse%2011g%20Active-Data-Guard%20datasheet.pdf
*Unique Advantages of Oracle Active Data Guard*
+Active Data Guard is an evolution of Data Guard technology, providing unique+
+performance advantages while leveraging all other enhancements included in Oracle+
+Data Guard 11g. For example, any Data Guard 11g physical standby database can+
+be easily converted to a Snapshot Standby. A Snapshot Standby is open read-write+
+and is ideally suited as a test system, able to process transactions independent of the+
+primary database. A Snapshot Standby maintains protection by continuing to receive+
+data from the production database, archiving it for later use. When tests are+
+complete, a single command discards changes made while open read-write and+
+quickly resynchronizes the standby database with the primary.+
The other link in the previous post is excellent and you really have to read it to understand the active data guard aspects.
Regards.

Creating physical standby database on same machine with dataguard

hi every one
i m new in oracle databases,
i read documentation to create physical standby databases,

i install windows xp on this vm and oracle 9i
now i want to create standby database on the same machine in some other drive configured with datagurd
virtual machine
OS windows xp
database oracle 9i
plz reply me how i do this
explain clearly step by step.
plz reply me in detail

When you need to have the standby database on the same server as the master, use lock_name_space in the init.ora.
This parameter permits this to occur without having to worry about changing the db_name.

What are the differences of creating a physical standby database with ASM?

I want to create a physical standby database for my 10g(10.2.0.1) database. But it is using ASM. Is it possible to create a standby database for a database using ASM?
What are the differences of creating a physical standby database with ASM?

tell us what your research shows and we'll try to
validate it. I am simulating Oracle ASM on a PC and I want to try
DataGuard on it now. So I am trying to create DataGuard
on an ASM system. The purpose is only learning and test.That's telling us how you are researching, not what you have observed.
Your research could have included looking at the documetation, and you might have found http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/scenarios.htm#sthref1642
which discusses exactly what you are looking for.

How to convert logical standby database to Physical Standby Database

Hi,
Does anyone know how to convert logical standby database(10.2.0.3) to Physical Standby Database(10.2.0.3)? Is this possible? If so,please give me steps for it.
Thanks.
Regards,
RJ.

I don't believe this to be possible. One of the steps invloved in the creation of a logical standby is the following:
ALTER DATABASE OPEN RESETLOGS;
This makes the logical standby a different incarnation of the db from the primary.
A physical standby is a binary copy of a primary db, a logical standby is a completely seperate db that just happens to get sql statements applied to it that are generated from a primary db, but is open read/write.
One avenue, though would be if you had flashback database enabled and you flashed back all the way to when the db was a physical standby and then rolled forward with the archived redo logs.
It's somewhat unlikely you are in that situation, but that is a possibility.
Indeed the 11g snapshot standby does this sort of thing:

How to check data in physical standby database?

Hi!
I'm maintaining physical standby database system. everyday, i must check tranfer and apply progress. I known, it operate very good. No archive gap is found.
But i want to check data in physical standby database that there is consistant with primary database, there isn't? What method do I use? How to do?
thankS

I hope the following will help
Verifying the Physical Standby Database
==========================================
Once you create the physical standby database and set up log transport services, you may want verify that database modifications are being successfully shipped from the primary database to the standby database.
To see the new archived redo logs that were received on the standby database, you should first identify the existing archived redo logs on the standby database, archive a few logs on the primary database, and then check the standby database again. The following steps show how to perform these tasks.
Step 1 Identify the existing archived redo logs.
On the standby database, query the V$ARCHIVED_LOG view to identify existing archived redo logs. For example:
SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME
2 FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
SEQUENCE# FIRST_TIME NEXT_TIME
8 11-JUL-02 17:50:45 11-JUL-02 17:50:53
9 11-JUL-02 17:50:53 11-JUL-02 17:50:58
10 11-JUL-02 17:50:58 11-JUL-02 17:51:03
3 rows selected.
Step 2 Archiving the current log.
On the primary database, archive the current log using the following SQL statement:
SQL> ALTER SYSTEM ARCHIVE LOG CURRENT;
Step 3 Verify that the new archived redo log was received.
On the standby database, query the V$ARCHIVED_LOG view to verify the redo log was received:
SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME
2> FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
SEQUENCE# FIRST_TIME NEXT_TIME
8 11-JUL-02 17:50:45 11-JUL-02 17:50:53
9 11-JUL-02 17:50:53 11-JUL-02 17:50:58
10 11-JUL-02 17:50:58 11-JUL-02 17:51:03
11 11-JUL-02 17:51:03 11-JUL-02 18:34:11
4 rows selected.
The logs are now available for log apply services to apply redo data to the standby database.
Step 4 Verify that the new archived redo log was applied.
On the standby database, query the V$ARCHIVED_LOG view to verify the archived redo log was applied.
SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG
2 ORDER BY SEQUENCE#;
SEQUENCE# APP
8 YES
9 YES
10 YES
11 YES
4 rows selected.
