Standby database query

Hi All,
How do i find the standby databases that are available for a primary database?
Suppose i have 2 standby databases for the primary. How do i find out the standby databases from the primary database other than checking the log_archive_dest parameter?
For eg: I have a 2 node rac database and a 2 node rac standby database.
I want to find out the standby node names and instance names from the primary node
OS:AIX
DB:10.2.0.5

Why the limitation/restriction from doing the obvious? Is this another "interview" question?

Relocating datafiles on standby database after mount point on stanby is ful

Hi,
We have a physical standby database.
The location of datafiles on primary database are at /oracle/oradata/ and the location of datafiles on standby database are at /oracle/oradata/
Now we are facing a situation of mount mount getting full on standby database so we need to move some tablespaces to another location on standby.
Say old location is /oracle/oradata/ and new location is /oradata_new/ and the tablespaces to be relocated are say tab1 and tab2.
Can anybody tell me whether following steps are correct.
1. Stop managed recovery on standby database
alter database recover managed standby database cancel;
2. Shutdown standby database
shutdown immediate;
3. Open standby database in mount stage
startup mount;
4. Copy the datafiles to new location say /oradata_new/ using os level command
4. Rename the datafile
alter database rename file
'/oracle/oradata/tab1.123451.dbf', '/oracle/oradata/tab1.123452.dbf','/oracle/oradata/tab2.123451.dbf',''/oracle/oradata/tab2.123452.dbf'
to '/oradata_new/tab1.123451.dbf', '/oradata_new/tab1.123452.dbf','/oradata_new/tab2.123451.dbf',''/oradata_new/tab2.123452.dbf';
5. Edit the parameter db_file_name_convert
alter system set db_file_name_convert='/oracle/oradata/tab1','/oradata_new/tab1','/oracle/oradata/tab2','/oradata_new/tab2'
6. Start a managed recovery on standby database
alter database recover managed standby database disconnect from session;
I am littelbit confused in step 5 as we want to relocate only two tablespaces and not all tablespaces so we have used.
Can we use db_file_name_convert like this i.e. does this work for only two tablespaces tab1 and tab2.
Thanks & Regards

8.3.4 Renaming a Datafile in the Primary Database
When you rename one or more datafiles in the primary database, the change is not propagated to the standby database. Therefore, if you want to rename the same datafiles on the standby database, you must manually make the equivalent modifications on the standby database because the modifications are not performed automatically, even if the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO.
The following steps describe how to rename a datafile in the primary database and manually propagate the changes to the standby database.
To rename the datafile in the primary database, take the tablespace offline:
SQL> ALTER TABLESPACE tbs_4 OFFLINE;
Exit from the SQL prompt and issue an operating system command, such as the following UNIX mv command, to rename the datafile on the primary system:
% mv /disk1/oracle/oradata/payroll/tbs_4.dbf
/disk1/oracle/oradata/payroll/tbs_x.dbf
Rename the datafile in the primary database and bring the tablespace back online:
SQL> ALTER TABLESPACE tbs_4 RENAME DATAFILE 2> '/disk1/oracle/oradata/payroll/tbs_4.dbf'
3> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
SQL> ALTER TABLESPACE tbs_4 ONLINE;
Connect to the standby database, query the V$ARCHIVED_LOG view to verify all of the archived redo log files are applied, and then stop Redo Apply:
SQL> SELECT SEQUENCE#,APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;
SEQUENCE# APP
8 YES
9 YES
10 YES
11 YES
4 rows selected.
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
Shut down the standby database:
SQL> SHUTDOWN;
Rename the datafile at the standby site using an operating system command, such as the UNIX mv command:
% mv /disk1/oracle/oradata/payroll/tbs_4.dbf /disk1/oracle/oradata/payroll/tbs_x.dbf
Start and mount the standby database:
SQL> STARTUP MOUNT;
Rename the datafile in the standby control file. Note that the STANDBY_FILE_MANAGEMENT initialization parameter must be set to MANUAL.
SQL> ALTER DATABASE RENAME FILE '/disk1/oracle/oradata/payroll/tbs_4.dbf'
2> TO '/disk1/oracle/oradata/payroll/tbs_x.dbf';
On the standby database, restart Redo Apply:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> DISCONNECT FROM SESSION;
If you do not rename the corresponding datafile at the standby system, and then try to refresh the standby database control file, the standby database will attempt to use the renamed datafile, but it will not find it. Consequently, you will see error messages similar to the following in the alert log:
ORA-00283: recovery session canceled due to errors
ORA-01157: cannot identify/lock datafile 4 - see DBWR trace file
ORA-01110: datafile 4: '/Disk1/oracle/oradata/payroll/tbs_x.dbf'

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.

Standby database is not applying redo logs due to missing archive log

We use 9.2.0.7 Oracle Database. My goal is to create a physical standby database.
I have followed all the steps necessary to fulfill this in Oracle Data Guard Concepts and Administration manual. Archived redo logs are transmitted from primary to standby database regularly. But the logs are not applied due to archive log gap.
SQL> select process, status from v$managed_standby;
PROCESS STATUS
ARCH CONNECTED
ARCH CONNECTED
MRP0 WAIT_FOR_GAP
RFS RECEIVING
RFS ATTACHED
SQL> select * from v$archive_gap;
THREAD# LOW_SEQUENCE# HIGH_SEQUENCE#
1 503 677
I have tried to find the missing archives on the primary database, but was unable to. They have been deleted (somehow) regularly by the existing backup policy on the primary database. I have looked up the backups, but these archive logs are too old to be in the backup. Backup retention policy is 1 redundant backup of each file. I didn't save older backups as I didn't really need them from up to this point.
I have cross checked (using rman crosscheck) the archive log copies on the primary database and deleted the "obsolete" copies of archive logs. But, v$archived_log view on the primary database only marked those entries as "deleted". Unfortunately, the standby database is still waiting for those logs to "close the gap" and doesn't apply the redo logs at all. I am reluctant to recreate the control file on the primary database as I'm afraid this occurred through the regular database backup operations, due to current backup retention policy and it probably might happen again.
The standby creation procedure was done by using the data files from 3 days ago. The archive logs which are "producing the gap" are older than a month, and are probably unneeded for standby recovery.
What shall I do?
Kind regards and thanks in advance,
Milivoj

On a physical standby database
To determine if there is an archive gap on your physical standby database, query the V$ARCHIVE_GAP view as shown in the following example:
SQL> SELECT * FROM V$ARCHIVE_GAP;
THREAD# LOW_SEQUENCE# HIGH_SEQUENCE#
1 7 10
The output from the previous example indicates your physical standby database is currently missing log files from sequence 7 to sequence 10 for thread 1.
After you identify the gap, issue the following SQL statement on the primary database to locate the archived redo log files on your primary
database (assuming the local archive destination on the primary database is LOG_ARCHIVE_DEST_1):
SQL> SELECT NAME FROM V$ARCHIVED_LOG WHERE THREAD#=1 AND DEST_ID=1 AND 2> SEQUENCE# BETWEEN 7 AND 10;
NAME
/primary/thread1_dest/arcr_1_7.arc /primary/thread1_dest/arcr_1_8.arc /primary/thread1_dest/arcr_1_9.arc
Copy these log files to your physical standby database and register them using the ALTER DATABASE REGISTER LOGFILE statement on your physical standby database. For example:
SQL> ALTER DATABASE REGISTER LOGFILE
'/physical_standby1/thread1_dest/arcr_1_7.arc';
SQL> ALTER DATABASE REGISTER LOGFILE
'/physical_standby1/thread1_dest/arcr_1_8.arc';
After you register these log files on the physical standby database, you can restart Redo Apply.
Note:
The V$ARCHIVE_GAP fixed view on a physical standby database only returns the next gap that is currently blocking Redo Apply from continuing. After resolving the gap and starting Redo Apply, query the V$ARCHIVE_GAP fixed view again on the physical standby database to determine the next gap sequence, if there is one. Repeat this process until there are no more gaps.
Restoring the archived logs from the backup set
If the archived logs are not available in the archive destination then at that time we need to restore the required archived logs from the backup step. This task is accomplished in the following way.
To restore range specified archived logs:
Run {
Set archivelog destination to '/oracle/arch/arch_restore'
Restore archivelog from logseq=<xxxxx> until logseq=<xxxxxxx>
To restore all the archived logs:
Run {
Set archivelog destination to '/oracle/arch/arch_restore';
Restore archivelog all;
}

Query regarding standby database state when primary is down or un-reachable

Hi
I want to know if there is any reflection on the standby database states when it's primary is down or not reachable? I want to use this information from standby node to determine if I can programatically execute (dgmgrl) failover operation or not? This is considering that the broker configuration has no fast-startfailover and no observer enabled/configured.
Thanks,
Yojana

YojanaYou don't have exactly such option,
But you have alternate for it. Whenever standby is unreachable to primary then from standby alert log file you can see informational messages as RFS: Possible network disconnect with primary database , So you can write a script to grep those contents and to mail alert, so that you can sense whether any issue with primary database.

Standby database error

Hi Guys..
I am using oracle 10.2.0.4.0 on windows 2003 server. I created a physical standby database successfully.
On standby database, I fired the following query

Hello to all
I have created a physical standby database ,I want make backup of it by rman and when I lose it's datafile I can restore it ,making backup and restore is fine but in recovery I encounter some problem
scenarios is follow
1- In rman I create a backup of standby database by this command:
backup database plus archivelog delete all input;
2- I run this comman in rman for recover standby database
run{
2> set until scn 1392701;
3> restore database;
4> recover database;
5> }
(1392701 is extracted from this query "SELECT MAX(NEXT_CHANGE#)+1 UNTIL_SCN FROM V$LOG_HISTORY LH,

do you know what is problem

hi
I myself have found the solution , when I recover the standby database
it do recovery but at the end of recovery it raise the error(RMAN-06054: media recovery requesting unknown log: thread 1
seq 118 lowscn 1392700) but if I begain redo apply before open the database
and I wait till all redo apply process start and communication between the
standby database and the primary database start, then I can
open the standby database and no error will raise
but if befor restarting redo apply I open the database I'll recieve the
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/app/oracle/oradata/sari/system01.dbf' error
thanks

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:

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:

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 to find the timestamp and SCN in the standby database?

Hai,
I have Oracle 9.2.0.4 RAC with 2 nodes in the production. The logs generated at these servers will be manully moved to my standby database and will be applied. To know what isthe maximum log files applied in the standby database, i am using the below mentioned query in the standby database,
Select thread#,max(sequence#) from v$log_history group by thread#
In general i am using "recover standby database until cancel" command and then checking the database with the above mentioned query whether all the logs are applied or not.
If i use time based or scn based recovery in standby database i.e., "recover standby database until time <time>" or "recover standby database until change <scn number>" , after completion of the recovery, apart from the message "Media recovery complete" or by seeing the alert log, is there any way to query the standby database, so that i can identify the time or scn upto which the archived redo log files got applied.

Hi Sridhar,
There should be some view which will have applied_scn information. There is one more option i can suggest, you can create a heart beat table in production with 2 column like scn and timestamp. Update this table every minute. From standby db you can query this table and get fair idea on applied_scn and timestamp.
While exporting you can export using flashback_scn by taking the value from heartbeat table of standby.
This heartbeat table is used very common in streams environment. Just see if this helps you.

Problem Converting standby database from snapshot to physical

Any help willl be greatly appreciated...
I am trying to convert a standby database that is in "snapshot" mode back to "physical" standby and I am encountering problems in the process from the "DGMGRL" command line.
Both instances are on the same physical machine. Everything was working fine untill I tried to change the db from snapshot to physical. The DGMGRL starts the conversion process and is able to shutdown but when trying to restart the instance is fails and reports that the service is not defined.
Here is the issue I am facing:

Thanks for the response.
So, here is the status now....with a little background...
After my original post, I started to read the manuals and I found the sql command to convert the database back from snapshot to physical standby (sb).
That worked fine and I had my snapshot sb back to physical sb.
So when you posted the suggestion, I already had my db in physical sb mode. I said no problem, I will convert it back to snapshot and then back again using dgmgrl instead of sql+
Well here is how my listener is configured now.
SID_LIST_I11G1 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = I11G1.MHOST)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1)
(SID_DESC =
(GLOBAL_DBNAME = I11G1SB.MHOST)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1SB)
(SID_DESC =
(GLOBAL_DBNAME = I11G1SB_DGMGRL)
(ORACLE_HOME = c:\app\mmj\product\11.1.0\db_1)
(SID_NAME = I11G1SB)
Then using dgmgrl I tried to change the db from p-sb to s-sb and the results are not good....

Not sure if the following (notice the typo in the service name) in the parameter (log_archive_dest_2) definition on the standby d/b has anything to do with this. I did not get this error when I initially converted to s-sb.
also I checked all my session notes, I did not type the command to set this parameter on the standby d/b and so it was not a typo on my part. However, it seems to have come from the rman script supplied with the obe. This script is supposed to clone the primary d/b to a standby db and in the process replace the string /i11g1/ with /i11g1sb/.

I am tempted to start all over again, but I'd rather use this opportunity to debug this issue (as a learning exercise). I can always start from scratch. That brings up another Q: What do I need to do to blow away all traces of the stand by database (including all the archive logs etc...) keeping my primary intact. I'd also like to blow away all snapshot and archive logs for the primary as well.

Logical Standby Database Not Getting Sync With Primary Database

Hi All,
I am using a Primary DB and Logical Standby DB configuration in Oracle 10g:-
Version Name:-
SQL> select * from v$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
PL/SQL Release 10.2.0.5.0 - Production
CORE 10.2.0.5.0 Production
TNS for Solaris: Version 10.2.0.5.0 - Production
NLSRTL Version 10.2.0.5.0 - Production
We have build the logical standby last week and till date the Logical DB is not sync. I have checked the init parameters and I wont see any problems with it. Also archive log destinations are also fine enough.
We have a important table named "HPD_HELPDESK" where record count is growing gradually whereas in logical standby it's not growing. There are some 19K record difference in the both the tables.
I have checked the alert log but it is also not giving any error message. Please find the last few lines of the alert log in logical Database:-

I am not able to trace the issue that why the records are not growing in logical DB. Please provide your inputs.

How do you know that there's such a gap between the tables?
If your standby db is a physical standby, then it is not open and you can't query your table without cancelling the recovery of the managed standby database.
What does it say if you execute this sql?
SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS FROM V$MANAGED_STANDBY;The ARCH processes should be connected and MRP waiting for a file.
If you query for the archive_gaps, do you get any hits?
select * from gv$archive_gapIf you're not working in a RAC environment you need to query v$archive_gap, instead!
Did you check whether the archives generated from the primary instance are transferred and present in the file system of your standby database?
I believe your standby is not in recovery_mode anymore or has an archive_gap, which is the reason why it doesn't catch up anymore.
Hope it helps a little,

PS: I'm working on 11g, so unfortunately I'm not quite sure if the views are exist in 10gR2. It's worth a try though!

How to get the date of the last transaction in a mounted standby database?

Hello,
Could you tell me how to get the date of the last transaction recorded in a MOUNTED standby database?
The following query doesn't work...because the database is not open...
select scn_to_timestamp(current_scn) from v$database;
Thanks

Hi,
You should be able to run the following command in mounted mode on standby database.
select current_scn from v$database;
then run the following to convert it to timestamp.
select scn_to_timestamp(99999999) from dual; *<-- Replace here the SCN value you got above. This needs to be run on the primary database due to standby database in mount mode.*
Alternatively you can also check at the alert.log file to find the last scn which has been applied.
Regards

How to apply the changes in logical standby database

Hi,
I am new to Dataguard. I am now using 10.2.0.3 and followed the steps from Oracle Data Guard Concepts and Administration Guide to setup a logical standby database.
When I insert a record to a table from the primary database side, when i query the same table from the logical standby database, it doesn't show the new records.
Did I miss something? What I want to do is when I insert a record in the primary db, then the corresponding record will be inserted in the standby db.
Or I totally misunderstand what Oracle data guard is? Any help are appreciated.
Denis
