Hi,
Can anyone please help me how to create Physical Standby Database without dataguard. As i am using Oracle 10.2.0.1 Standard Edition for production databases.
Please find the specifications of my server :
Database : Oracle 10.2.0.1(Standard Edition)
Server : Linux 4.0(32 bit machine)
As we know that Dataguard cannot be created in Standard Edition as we dont have that option in this edition. So please help me how to create the physical standby database.
Thanks in advance.

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 Patel

Hello;
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.

Problem while creating Physical standby database on remote Server

Hi
I try to create a physical standby datbaase using OEM 10gr2, it is working when I create on same server. No issue but when I try to create same on remote server it is giving below warning and process failing. Please let me know what needs to be down in this senario...
It is showing redo log information in v$log and v$log_file but not creating physically on PHYSICAL Standby instance..
I appriciate your help and ur time too..
These messages are from PRIMARY database alert*.log file
There is space for up to 12 standby redo logfiles

Well, it is simply warning that "Creating a physical
standby controlfile, when OMF is enabled on the primary
database, requires manual RMAN intervention to resolve OMF
datafile pathnames.
NOTE: Please refer to the RMAN documentation for procedures
describing how to manually resolve OMF datafile pathnames"
For instance, the path for the logfile name in "ALTER DATABASE ADD STANDBY LOGFILE 'srl5.f' SIZE 52428800" may need to be changed manually. It is advisable to check the mentioned documentation.

Creating a Standby Database with the Same Directory Structure

Hello gurus,
I am self-learning the feature Oracle Data Guard, so I am testing it on Oracle 10g R2.
At Oracle documentation there is a section F.4.: Creating a Standby Database with the Same Directory Structure*, that explains how to create a standby database with RMAN but there is something that I don´t understand:
In the standby server, I created a database with the SID equal to production database* with the objetive to have the same directory structure, but when I try to startup nomount the standby database with pfile appear this expected error:
ORA-16187: LOG_ARCHIVE_CONFIG contains duplicate, conflicting or invalid attributes
So my question is: Is possible have the Same Directory Structure on both: Production and StandBy server?
Thanks in advanced.

Uwe and mseberg: thanks for your quick answers
I have a doubt: How can you have the same directory structure if you have differents SIDs?, for example if you follow the OFA suggestions you would must have:
On Production server: */u01/app/oracle/oradata/PRIMARY/system.dbf*
On StandBy server: */u01/app/oracle/oradata/STANDBY/system.dbf*
Or you created the directory structure manually on StandBy server? For example replacing the string STANDBY* to PRIMARY* before create the database using dbca.
Do you understand my doubt? Excuse me for my english.
Thanks.

Looking to use DG Broker to create new standby database

Hello,
I'm looking for a good document that can help me to create another standby database on a new server.
I'm running Oracle 11.2 EE on Solaris 10.
We already have one standby database, but now, I want to create another standby database on another server, which ultimately I will make primary and then replace and destroy our current primary/standby databases.
Also, just for the heck of it, I tried to look in our DB Console, and the "Add standby database" is grey'd out.
Is this because I am only using DB Console, and not Grid?
But if that were the case, why would the option even be in DB Console, or perhaps is there a lmiitation to the number of standby databases you can manage with DB Console?

1) Do not confuse Data Guard Broker and Enterprise Manager: DG Broker is mainly a background process (DMON) that can be controlled by EM or with DGMGRL on the command line
2) Only the Grid Control flavor of EM can manage Data Guard Configurations - regardless of the number of Primary or Standby Databases
3) DGMGRL cannot create a new Standby Database - Grid Control can
Kind regards

How to create tree by database table

hello sir ,
my table is as follows,
NAME LINK ID PID ROLLID
User mgt. f?p=131:1: 1 - 10 ////root node///
district 10 1 1 child
Roles 16 14 4 child
Users 11 10 1 child
ROLLID is given from another table whis is (ROLES). i making tree by the combinations of id , pid, & roll id. by the roll id i can manage the tree to do not display specific nodes to specific users.
ROLE table as :

but i think it is very complicated process . give me solution about it
also i have to give my images to each node. how can i do that?

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

Differences in creating a Standby database in RAC

Hi All
   SO...: Solaris 11 SPARC 64
   DB...: 11.2.0.3.6 (64 bits)
   My experience regarding creating Physical Standby Databases is restricted in only single instances to single instances. I am reading the book "Oracle Database 11g Release 2 High Availability", but, in parallel, i would like to hear from the experienced DBAs here some opinions and recomendations in how to implement a RAC to RAC solution. Below are my doubts:
   1) In single instance, using RMAN Backup to create the Physical Standby, i have to create manually a static Listener Entry. But in a RAC env, the listener is a resource, so, i have to create that resource in the Clusterware manually, or there is other approach?
   2) I have to create a pfile and start the instance in NOMOUNT mode, but in RAC, i have to start all the nodes in NOMOUNT, or just one node is sufficient?
   3) The archives will be replicated from FRA to FRA. Is this the best approach?
   My main concern is with the Listener and SCAN questions... If you have any considerations, they will be most welcome.
   Thanks in advance.

How to create a standby redolog from rac to non rac ??

Hi,
How to create a standby redolog from rac to non rac DR setup..???
in rac we can create with specifying thread number for each instances..... but this will be replicating to standby ....so how this will act/create on single DR??
pls help

Thanks Shivanandha,
(maximum number of logfiles for each thread + 1) * maximum number of threads
Using this equation reduces the likelihood that the primary instance's log writer (LGWR) process will be blocked because a standby redo log file cannot be allocated on the standby database. For example, if the primary database has 2 log files for each thread and 2 threads, then 6 standby redo log file groups are needed on the standby database.In maximum performance mode you can keep same number of redo logs but having one more redo log member for each thread is recommended and mandtory for other protection modes.

Yes, even your DR is RAC or non-RAC, you must have both threads, because each instance information exist on own thread, So to perform redo transition from both the instances, you must have both standby redo log threads even though if it is non an RAC DR.
Hope This helps.

If the production database i down, how to switch to standby database using the replication environment in ASsE

This question is in Business Continuity Plan (BCP)
if the production database is down, how to switch to standby database using the replication environment in ASE

Assuming you're referring to Sybase's Replication Server (repserver) product ...
Repserver moves data changes from one database to another.
Repserver can't 'switch' your application to use a different database; something outside of repserver has to do the actual switching.
If your application happens to be connecting to your ASE via Sybase's OpenSwitch (or similar) product, then OpenSwitch would be responsible for switching your application to use the standby database. Whether you have OpenSwitch perform the switch automatically, or via a manual command, is up to your BCP requirements.
If your application connects directly to ASE then you'll have to decide how/when to get your application to switch to the standby database. In the simplest form this would require shutting down the application, making sure replication is quiesced (ie, all in-flight transactions have been applied to the standby database), modify the interfaces/sql.ini file (used by your application) to point to the standby database, make any customized changes to the standby dataserver/database (eg, unlock application logins, take databases out of 'dbo use only' mode, etc), and startup the application (at this point it should connect to the standby database per the changes to the interfaces/sql.ini file).
