Physical standby is active
Hi,
I am implementing Data Guard on Oracle 10.2.0.1 database the OS is windows 2003 SP2.
the issue is:
when I shutdown the standby database and startup it back, the database open and active.
I am expecting that the database will be in a stand by mode after restarting it.
so, why the database is not started back in the standby mode?
thanks in advanace

Hi mseberg,
I wanna to take your attention to:
1- the primary and physical standby is working fine.
2- the logs are transfered to the standby server and applied correctly.
I startup the standby using the following:
startup mount
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;after that
shutdown immediate
startupthe standby database in the open mode.
*.FAL_SERVER=MSTRHQ
*.FAL_CLIENT=SLVHQ
*.standby_file_management='AUTO'
*.db_unique_name='SLVHQ'
db_file_name_convert(not defined)
*.log_file_name_convert='junk','junk'
*.LOG_ARCHIVE_DEST_1='LOCATION=E:\oracle\Archives
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
DB_UNIQUE_NAME=SLVHQ'
*.LOG_ARCHIVE_DEST_2='SERVICE=MSTRHQ LGWR ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=MSTRHQ'
*.LOG_ARCHIVE_DEST_STATE_1='ENABLE'
*.LOG_ARCHIVE_DEST_STATE_2=ENABLE
*.log_archive_max_processes=30
I have been used the same SID name for both primary and standby databases, also the same folder structure and drives on the two machines.
I have been created the standby controlfile using
ALTER DATABASE CREATE STANDBY CONTROLFILE AS 'c:\stdby01.ctl';
Thanks for ur cooperation.

Hi,
We have Oracle 11.2.0.4 and are currently using Active Data Guard on a physical standby. My boss wants me to use Goldengate
to replicate several schema from Oracle to SqlSserver. She doesn't want to touch the Primary, which is in production. Would it be better
to setup a Logical standby for Goldendate to use, in addition to the Physical standby? Or will it be sufficient to use the Physical standby?
The application tables don't all have primary keys. I'm trying to decide if the Logical standby adds another layer of complexity or would
introduce delays in getting the data from Oracle to Sqlserver.
Thanks in advance,Hi,
In this case I recommend you to use physical standby + Golden gate with ALO mode. You might have sligthly more trouble in logical standby. it means you might have more trouble at Goldengate's extract side.
You said
The application tables don't all have primary keys.
so you have to add keycols on replicat side.
I recommend you to add an index which should consist of keycols columns. it will be necessary for replicat performance.

Hi all,
11.2.0.1
Aix 6.1
I still am confused how do our DG physical standby be activated and up-to-date in case when disaster happens?
My boss tasked me a service-level-agreement, to check every hour that the archivelogs should be latest updated to the standby db.
Does this mean I have to check our database every hour, 24-hrs a day? What has this DG has done to my life then?
Is there a way to check if the arhivelogs are not applied within an hour? and send SMS to me if there is such a gap?
I only have this script:
SELECT PROCESS, CLIENT_PROCESS, SEQUENCE#, STATUS FROM V$MANAGED_STANDBY
PROCESS CLIENT_P SEQUENCE# STATUS
ARCH ARCH 530 CLOSING
ARCH ARCH 531 CLOSING
ARCH ARCH 0 CONNECTED
ARCH ARCH 529 CLOSING
MRP0 N/A 532 WAIT_FOR_LOG
RFS UNKNOWN 0 IDLE
RFS LGWR 532 IDLE
Can you share me how do you manage your standby DB? Does it disturb you during sleeping time, midnight, weekends, holidays?
I thought this dataguard is made to make dba's life easy? Why is it getting more complicated????
Thanks a lot,
zxyThanks Sunny & Sve,
I am just new to this company and they have the Oracle Partner consultants configured the DataGuard. Maybe the ASYNC you mentioned was already configured by them?
And we just do not use it? How can I check if it was already configured?
Does the script below showing "MRP0 WAIT_FOR_LOG" show that archivelogs are currently updated, hence it is waiting for logs?
SELECT PROCESS, CLIENT_PROCESS, SEQUENCE#, STATUS FROM V$MANAGED_STANDBY
PROCESS CLIENT_P SEQUENCE# STATUS
ARCH ARCH 530 CLOSING
ARCH ARCH 531 CLOSING

Active dataguard physical standby
Hi,
Is it possible to create additional tables and do DML operations on them ( these tables will not be present on primary db) in physical standby database created by active data guard.
Regards,
prasad.Is it possible to create additional tables and do DML operations on them ( these tables will not be present on primary db) in physical standby database created by active data guard.Prasad,
Here Active datagaurd feature is only for READ ONLY or reporting purpose, where you can perform only Select queries which is from 11gRx at the same time recovery also will be active.
If you want to open database in Read & Write , There there would be no consistent with Primary database, These behaves as different databases.
So Either you have to use flashback option after completing your REad & Write options,
Again you will lost all of the data, whatever you performed DML operations. So this is no use again.
You can use this note for that procedure *How To Open Physical Standby For Read Write Testing and Flashback [ID 805438.1]*
But i can say conclusion to make your standby high available your DML operations are not supported, ofcourse supported but its not High availability.
Hope this clears.

Creating physical standby database from another physical standby database
hi,
We have one production database and one physical standby of the production. Now we have situation where we need to create one database from either production or from standby. As production is loaded we can not do it using active database option. Now we have the only option to copy the database from standby.
As of now we open the standby and copy it using rman duplicate database and again we put it back to standby mode.
Is it possible to create standby database from standby database only?
Oracle version : 11.1.0.7.0
I have seen procedure allowing to do the same in version 11.2.0.3. I have tried searching for the difference but didn't find when this feature was introduced.
Thanks,
Ketul PatelHello;
Active duplicate should work when connected to Standby as source Database. However there's a bug 11715084 which is not fixed until version 11.2.0.4.
If patch 11715084 is available for your version it may work, but all the 11.1.0 are gone so I have no way to test.

Hello,
I am attempting to create a physical standby database, following this guide:
http://www.oracle.com/global/uk/education/downloads/uwe_data_guard.pdf
as well as the oracle documentation on Data Guard. Using Oracle 11gR2 patched at #7 running on Windows Server 2008.
I've set all the parameters, created password files and checked connectivity. Hopefully correctly. I will post pfile exports at the end.
Here is where I hit a dead end.
RMAN> connect target system/password@HPROD89
connected to target database : HPROD89 (DBID)
RMAN> connect auxiliary sys/password@HPROD89STND
connected to auxiliary database: HPROD89STND (not mounted)
RMAN> duplicate target database for standby from active database;Error from spool. I need to spool the file to get the error code, otherwise the only thing rman provides is a "error message stack follows" message with nothing after that.
RMAN-03002: failure of Duplicate Db command at 11/19/2010 21:24:04
RMAN-06136: ORACLE error from auxiliary database: ORA-03114: not connected to ORACLEI'm running rman on the standby server with the database in NOMOUNT as the guide linked above suggests. This raises a simple question to start with: what server do I run rman on? The one with the primary database, or on the standby?
I hope it's just because it's getting late, but this issue has me confused .. rman clearly connects the auxiliary, but when trying to perform the actual duplication, it's not connected.
Thanks for input.

Create ONLINE logfile in physical standby database
We have created a physical standby database with rman duplicate command on a remote server
"duplicate target database for standby dorecover nofilenamecheck"
When I see the standby server...Online logfiles are not created however its relevant entries are there in V$LOG and V$LOGFILE views.
I guess it is the default behaviour of duplicate command in RMAN and we can not specify LOGFILE clause when we create standby database.
Now the problem is we could not drop the online logfile on standby database since it's status is "CURRENT", "ACTIVE".
Since the ONLINE LOGFILE are not actually created , "ALTER DATABASE CLEAR LOGFILE GROUP " command returns with error as it could not find the file in the server.
So How we can drop the current/active online logfile and add new ones in standby db?I'm assuming you have physical standby. Here are step I did in the past.
1) create a backup control file
2) bring the database back using the "recreate control file" it the trace file BUT you need to remove or comment out the line that has the corrupt or missing redo log file. And don't forget to add the tempfile after you recreate the controlfile
example:
alter database backup controlfile to trace;
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS FORCE LOGGING ARCHIVELOG

Logical and Physical Standby Practice
Hello Gurus
I am now attempting to practice Oracle Data Guard and in this direction I understand since 10g we have logical standby server as well as a physical standby server. While I am gathering information and knowledge about the data guard as is and varisous modes and types possible with oracle 10g and 11g in specific, an attempt to upgrade my self and learn these set-ups and understand them in detail.. I come to you for some guidence..
I am referring to Oracle Documentation for these details. At the same time I also approach you to share your experiences .. may be a link apart from the documentation of oracle which you might want to refer me to use as a quick reference.. some thing that a person like me .. fairly new to this set-up understand it and then attempt to come up with one..
This is for my practise and learning purpose.
Sarat.Logical Standby was already introduced in 9i. It differs from physical standby in the way, the redo protocol, transmitted from the primary, gets used to actualize the standby. With logical standby, you have SQL APPLY - basically, we try to generate the same SQL that was done on the primary from the redo protocol that was written on behalf of that SQL on the primary. That SQL then is done on the OPEN instance at the logical standby.
In case of a physical standby, the redo protocol from the primary is used to do RECOVERY - called REDO APPLY - to actualize the standby.
Since 10g, the sames protection levels can be achieved with logical or physical standby.
Drawback of logical standby: Not all kinds of SQL and all datatypes are supported
Drawback of physical standby: It is mounted (versions before 11g) while being recoverd - or in 11g, REDO APPLY in READ ONLY status is possible but comes with an extra charge (ACTIVE DATA GUARD feature).
If you look on my Blog, I have some examples about creating physical & logical standby DBs
Kind regards
Uwe

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,
SujitDear 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.

if I disable the system triggers using
ALTER SYSTEM SET "_system_trig_enabled"=FALSE scope=both;
The error doesn't appear but when trying to switch to active dataguard the open_mode goes from READ ONLY to MOUNTED rather than READ ONLY WITH APPLY
Any help much appreciated
Edited by: phil74 on 12-Aug-2011 07:22Have you checked what your guard status is set to?
SQL> SELECT guard_status from v$database;I've had a similar issue before but with a standby, whereby the status was set to ALL. This means all users apart from SYS are unable to make changes on the database.
My resolution was to set the status to standby:
SQL> ALTER DATABASE GUARD STANDBY;You may wish to set the guard status to NONE however.
I took some notes:

Hi, all, I have a Dataguard, the primary db is a RAC with three nodes, the standby db is a physical standby. the dataguard are all oracle 10.2.0.3 on solaris 9 sparc system
Now, my standby db did not apply the archivelogs,there are some errors in standby alert log :

then ,how to fix the dataguard and apply the archivelog on standby db ?
why I can found 2984028173 with 22648,but can not found 2984013192 ??
and why there have three 22648 with different applied status and deleted status on standby db ???

Physical standby database standby redo log problem
Hello
We have a physical standby database , I've created some standby redo log files but my problem is that they aren't used,
their status in v$stanby_log view is UNASSIGNED
and I see this message (ORA-16086: standby database does not contain available standby log files) in primary database alert_log file
while when I run "alter system switch logfile" in the primary database it transfer redo logs to the physsical standby database
and archive log file will be created in standby database
I've even recreated the standby redo log files and I added new ones to them but the problem wasn't solved
Do you know what is problem ?

No space in recovery area for active standby redo logs
The primary database is operating in MAXIMUM PROTECTION
or MAXIMUM AVAILABILITY mode, and the standby database
does not contain adequate disk space in the recovery area
to safely archive the contents of the standby redo logfiles.
ORA-16086: standby database does not contain available standby log files
when I saw this line "No space in recovery area for active standby redo logs" I thought that STANDBY_ARCHIVE_DEST parameter points where that there is no enough space , but when I consider I found out that points a directory on disk a "sda" that has enough space , I don't know what that means

DB link for physical standby database
Hi All ,
I'm facing the below error on primary while trying to create a db link pointing to the 10g standby database which is in mount stage.
SQL> create database link synct connect to system identified by 123 using 'stdby';
Database link created.
SQL> select max(sequence#) from v$archived_log@synct where applied='YES';

My requirement is i need to get max(sequence#) of standby database from primary database using db link.
what i was trying to do is
on primary get max(sequence#) & get max(sequence#) of standby using db link and compare both if the gap differene is more than 10 send a mail.
Any suggestions will be really helpful976422 wrote:

Post Standby/DataGuard/ADG all questions further in Oracle Discussion Forums » High Availability » Data Guard
If you try to connect any users other than SYS in standby the error is very much expected. Of course you can connect with other users if you open database in OPEN READ ONLY mode, from 11gRx you can connect with other users even MRP is running if you are using ADG(active Data Guard licensed) .
I like to know, what you want to achieve by creating DB Link on physical standby database? Which is not allowed.
Database version is 10.2 standard edition
My requirement is i need to get max(sequence#) of standby database from primary database using db link.
what i was trying to do is
on primary get max(sequence#) & get max(sequence#) of standby using db link and compare both if the gap differene is more than 10 send a mail.
Any suggestions will be really helpfulNote:- Standard edition, Data Guard not enabled.
To use this you should use Oracle Net Service, you no need of DB Links.
Ex:- sqlplus sys/****@standby as sysdba
Here standby refers to Oracle net service, Where you will have entries in $ORACLE_HOME/network/admin/tnsnames.ora file.
