Logical Standby Database Down

I am new to the Data Guard process and i wanted to know the following:
I have a 9i Primary DB that ships to a Logical Standby Database, however if the logical standby database goes down for whatever reason, (hardware failure) it is unreachable, what can I configure to alert me that the has occurred?
Is it something on the Primary DB that alerts me that the redo logs are perhaps not being processed? Does one use the Dead Connection Detection parameter SQLNET.EXPIRE? How do I identify the Primary to Standby connection is down amongst so many user connections?
Many Thanks

You will have an error for the archive log destiantion that is for your standby
For like 10g or 11g using a SYNC or ASYC the logwr reports the issue the archiver process will report same as well.
LGWR: Error 1041 disconnecting from destination LOG_ARCHIVE_DEST_2 standby host 'testsb'
so for your archive destination for you standby look for errors to the destination and then alert.

Logical Standby Database with 10g+ASM on both sides??

Hi out there,
is there a known way to establish a logical standby database on 10g, if both
sides are running with an ASM setup?
I've tried to create one out of a physical standby database (which is set up
and running w/o any problems), like a book suggested me to do.
The procedure was:
1. switch on supplemental logging
2. prepare initiation parameters (for archive logging etc.) on both sides for
logical stb.
3. shut down the phyiscal standby
4. alter database create logical standby controlfile as '<path>'; on the
primary, transfer the controlfile to the standby db. Here I had to use RMAN
to copy the controlfile into the ASM System, and modify the initfile/spfile
in order to use the controlfile. No problem so far.
5. mount the standby database, alter database recover managed standby database
disconnect; -> At this point, the alert log complained about non-available
datafiles.
6. alter database activate standby database; --> fails ("needs recovery") due
to last point.
The trouble is, the controlfile created at point 4 cointains wrong paths to
the datafiles. Since I can not have the same disk group name on the standby
system, and since ASM renames the stored datafiles by its own, the complaints
of point 5 are comprehensible, but nevertheless annoying.
I tried to backup a controlfile to trace and change the paths, but at after
mounting the standby with this controlfile and proceeding at point 5, the
system says "<path> is not a standby controlfile"
Is there a different way of creating a "Logical Standby Database with 10g+ASM
on both sides"? Metalink said nothing about LogStby and ASM.
Best regards and thanks in advance,
Martin

I'm not sure if this will work but try:
1. create trace control file (you did it)
2. change paths (you did it)
3. recrate control file (you did it)
... there was error occured during mount before
so mount database (not as standby)
4. create standby control file (from recreated control file)
5. shutdown instance, replace control file with new standby control file or replace the control filename in parameter file.
6. mount as standby
What happend?
Update: Tested on my side and it has worked fine... How about you?

ORA-01403: no data found on LOGICAL STANDBY database

Hi ,
Logical Standby issue :
Oracle 10.2.0.2 enterprise edition .
M Working on LOGICAL Standby since 1 yrs but still i havent got this ......................................
I m getting countinuously no data foud errror on logical standby database .
I found the table causing the proble(db_logstdby_events) and skipped that table and instanciated table using bwlow package:
exec dbms_logstdby.instantiate_table (.......................................
but when i start apply process on logical standby it again give no data found for new table :
Even i tried to instantiate the table using EXPORT/IMPORT during down time but the same facing same problem .
As much as i known abt the error that is :
table1
id
10
20
30
Now if sql apply process on logical standby tries to performe the update transaction(for example) as belows
update table1 set id=100 where id=50;
above query will not be completed cos it will never find the values 50 which is not in table .Thts why this error comming ..
Now my worry is ... no users dare to change/make such changes on Logical standby .So if there is no changes in tables then sqll apply should get all the values to be needded for an update ......
watingggg guyssss/......

Troubleshooting ORA-1403 errors with Flashback Transaction
In the event that the SQL Apply engine errors out with an ORA-1403, it may be possible to utilize flashback transaction on the standby database to reconstruct the missing data. This is reliant upon the undo_retention parameter specified on the standby database instance.
ORA-1403: No Data Found
Under normal circumstances the ORA-1403 error should not be seen in a Logical Standby environment. The error occurs when data in a SQL Apply managed table is modified directly on the standby database, and then the same data is modified on the primary database.
When the modified data is updated on the primary database and received by the SQL Apply engine, the SQL Apply engine verifies the original version of the data is present on the standby database before updating the record. When this verification fails, an ORA-1403: No Data Found error is thrown by Oracle Data Guard: SQL Apply.
The initial error
When the SQL Apply engine verification fails, the error thrown by the SQL Apply engine is reported in the alert log of the logical standby database as well as a record being inserted into the DBA_LOGSTDBY_EVENTS view. The information in the alert log is truncated, while the error is reported in it's entirety in the database view.
LOGSTDBY stmt: update "SCOTT"."MASTER"
set
"NAME" = 'john'
where
"PK" = 1 and
"NAME" = 'andrew' and
ROWID = 'AAAAAAAAEAAAAAPAAA'
LOGSTDBY status: ORA-01403: no data found
LOGSTDBY PID 1006, oracle@staco03 (P004)
LOGSTDBY XID 0x0006.00e.00000417, Thread 1, RBA 0x02dd.00002221.10
The Investigation
The first step is to analyze the historical data of the table that threw the error. This can be achieved using the VERSIONS clause of the SELECT statement.
SQL> select versions_xid
, versions_startscn
, versions_endscn
, versions_operation
, pk
, name
from scott.master
versions between scn minvalue and maxvalue
where pk = 1
order by nvl(versions_startscn,0);
VERSIONS_XID VERSIONS_STARTSCN VERSIONS_ENDSCN V PK NAME
03001900EE070000 3492279 3492290 I 1 andrew
02000D00E4070000 3492290 D 1 andrew
Depending upon the amount of undo retention that the database is configured to retain (undo_retention) and the activity on the table, the information returned might be extensive and the versions between syntax might need to be changed to restrict the amount of information returned.
From the information returned, it can be seen that the record was first inserted at scn 3492279 and then was deleted at scn 3492290 as part of transaction ID 02000D00E4070000. Using the transaction ID, the database should be queried to find the scope of the transaction. This is achieved by querying the flashback_transaction_query view.
SQL> select operation
, undo_sql
from flashback_transaction_query
where xid = hextoraw('02000D00E4070000');
OPERATION UNDO_SQL
DELETE insert into "SCOTT"."MASTER"("PK","NAME") values
('1','andrew');
BEGIN
Note that there is always one row returned representing the start of the transaction. In this transaction, only one row was deleted in the master table. The undo_sql column when executed will restore the original data into the table.
SQL> insert into "SCOTT"."MASTER"("PK","NAME") values ('1','andrew');
SQL> commit;
The SQL Apply engine may now be restarted and the transaction will be applied to the standby database.
SQL> alter database start logical standby apply;

Creating a new schema in a Logical Standby Database

Hi All,
I am experimenting with logical standby databases for the purpose of reporting, and have not been able to create a new schema in the logical standby database - one of the key features of logical standbys.
I have setup primary and logical standby databases, and they seem to be running just fine - changes are moved from the primary to the standby and queries on the standby seem to run ok.
However, If I try to create a new schema on the logical standby, that does not exist on the primary, I get "ORA-01031: insufficient privileges" errors when I try to create new objects.
Show below are the steps I have taken to create the new schema on the logical standby. Any help would be greatly appreciated.

Logical Standby Database in NOARCHIVE Mode

Hi,
I have configured a Logical Standby Database for Reporting purposes. A Physical Standby Database is running for MAA. i.e. in case of Role Transition (switch/Failover) the Physical Stdby Db will get the role of the Primary.
The logical standby database is creating a lot of Archive Redologs files, nearly every minute. Redolog files are 50MB and there is no work done in db during the time. I'm NOT using Standby Redolog files.
Is there a need for logical standby database to be in NOARCHIVELOG mode? The Primary is definatley in ARCHIVELOG mode.
Thanks for any responses.
regards
Sahba

hi,
well there are two things to the above:-
1. there was an archive file nearly every minute:
this is due to a db recovery. for some reason, the db was in inconsistent state, after a sudden shutdownof the OS. I was on a test environment, on windows vista, unfortunately. unimportant ... a reboot solved it.
2. Logical standby db in NOARCHIVE MODE when setup for the purpose of Reporting.
As long as the MAA configured for the primary db, such as physical standby db, and a second, the logical standby db setup purely for the purpose of reporting, which then can run with NOARCHIVELOG mode, after converting the physical standby db to logical.
logical standby db uses Streams architecture, so this method brings cost, time and performance advantages to the customer.

How to delete the foreign archivelogs in a Logical Standby database

How do I remove the foreign archive logs that are being sent to my logical standby database. I have files in the FRA of ASM going back weeks ago. I thought RMAN would delete them.
I am doing hot backups of the databases to FRA for both databases. Using ASM, FRA, in a Data Guard environment.
I am not backing up anything to tape yet.
The ASM FRA foreign_archivelog directory on the logical standby FRA keeps growing and nothing is get deleted when
I run the following command every day.
delete expired backup;
delete noprompt force obsolete;
Primary database RMAN settings (Not all of them)
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 9 DAYS;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE DB_UNIQUE_NAME 'WMRTPRD' CONNECT IDENTIFIER 'WMRTPRD_CWY';
CONFIGURE DB_UNIQUE_NAME 'WMRTPRD2' CONNECT IDENTIFIER 'WMRTPRD2_CWY';
CONFIGURE DB_UNIQUE_NAME 'WMRTPRD3' CONNECT IDENTIFIER 'WMRTPRD3_DG';
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
Logical standby database RMAN setting (not all of them)
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 9 DAYS;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
How do I cleanup/delete the old ASM foreign_archivelog files?

OK, the default is TRUE which is what it is now
from DBA_LOGSTDBY_PARAMETERS
LOG_AUTO_DELETE TRUE SYSTEM YES
I am not talking about deleting the Archive logs files for the Logical database that it is creating, but the Standby archive log files being sent to the Logical Database after they have been applied.
They are in the alert log as follows under RFS LogMiner: Registered logfile

Creating logical standby database

Hi all,
10.2.0.1
Following this link
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm
Where do i need to issue these statements:
SQL> EXECUTE DBMS_LOGSTDBY.BUILD;
SQL> ALTER DATABASE RECOVER TO LOGICAL STANDBY db_name;
on physical standby or primary database.
I issued the first stament on primary and second on physical standby .
IN the alert log of standby,i have the following entries.
Wed Jan 20 15:34:28 2010
Converting standby mount to primary mount.
Wed Jan 20 15:34:28 2010
ACTIVATE STANDBY: Complete - Database mounted as primary (treasury)
*** DBNEWID utility started ***
DBID will be changed from 306589979 to new DBID of 330710340 for database
.........................I am trying to create a logical standby database after creating a physical standby database.
It seems standby changed to primary which was not desired.
Thanks

Not tried myself, but you might want to have a look at this URL.
It appears to suggest that you need to change names of datafiles as well as value db_name explcitly on standby.

Creation of Logical Standby Database Using RMAN ACTIVE DATABASE COMMAND

Hi All,
I am in confusion how to create logical standby database from primary database using rman active database command.
What i did:-
Create primary database on machine 1 on RHEL 5 with Oracle 11gR2
Create standby database on machine 2 on RHEL 5 With Oracle 11gR2 from primary using RMAN active database command
Trying to create logical standby database on machine 3 on RHEL 5 with Oracle 11gR2 using RMAN active database command from primary.
The point which confuse me is to start the logical standby in nomount mode on machine 3 with which pfile like i create the pfile for standby database do i need to create the pfile for logical standby db.
I done the creation of logical standby database by converting physical standby to logical standby database
I am following the below mentioned doc for the same:
Creating a physical and a logical standby database in a DR environment | Chen Guang&#039;s Blog
Kindly guide me how to work over the same or please provide me the steps of the same.
Thanks in advance.

Thanks for your reply
I already started the logical standby database with pfile in nomount mode. And successfully completed the duplication of database. by mentioning the DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT parameter.
But i am not able to receive the logs on the above mentioned blog i run the sql command to check the logs but getting "no rows selected"
My primary database pfile is:

Logical Standby Database and XMLDB

I couldn't find a proper group to post this message and thought I would try here.
I want to set up a Logical Standby Database for our production database server 9.2.0.4.0 with XMLDB. I am having problem with some system tables that were created when I registered some XML schemas.
These tables are in the standby database but Oracle complains the object does not exist.
Any idea?

>
The "may be" is because I have tested flashback of a physical standby to before resetlogs, but not a logical standby.
>
A physical standby keeps the DBID of the primary - a logical standby does not. That is exactly the problem that restricts the reconversion into physical from logical, and you did not encounter that problem.
>
I haven't used "keep identity" but from what I read it relates to "convert to physical" not "flashback database".
>
Exactly. And that is what the OP wants to do: convert to physical (from logical).
You mentioned that this might be possible with flashback.
Problem: During the conversion from physical to logical, the DBID gets changed unless you specify (in 11g) KEEP IDENTITY. This would make it possible to reconvert into phyiscal from logical.
In short: If there is no solution for the changed DBID of the logical standby in order to flashback it into physical as you suggested, then it is not possible .
When I saw your first answer, I thought that you might have a solution in mind in order to solve that obvious problem. Sorry for having bothered you.
Kind regards

Logical Standby databases

Hi,
When we say "Logical Standby Databases are logically identical to primary databases although the physical organization and structure of the data can be different." what does it exactly means?
Does it mean that in logical standby tablespace name, schema name, table name, column names etc can be different and still has the same data as primary?
Does it mean that we can exclude indexes and constraints as present in primary?
Only the data should match with primary word by word, value by value?
I am asking this as i have never worked in a logical standby database but i seriously want to know.
Please answer.
Regards,
SID

Physical standby differs from logical standby:
Physical standby schema matches exactly the source database.
Archived redo logs and FTP'ed directly to the standby database which is always running in "recover" mode. Upon arrival, the archived redo logs are applied directly to the standby database.
Logical standby is different from physical standby:
Logical standby database does not have to match the schema structure of the source database.
Logical standby uses LogMiner techniques to transform the archived redo logs into native DML statements (insert, update, delete). This DML is transported and applied to the standby database.
Logical standby tables can be open for SQL queries (read only), and all other standby tables can be open for updates.
Logical standby database can have additional materialized views and indexes added for faster performance.
Installing Physical standbys offers these benefits:
An identical physical copy of the primary database
Disaster recovery and high availability
High Data protection
Reduction in primary database workload
Performance Faster
Installing Logical standbys offer:
Simultaneous use for reporting, summations and queries
Efficient use of standby hardware resources
Reduction in primary database workload
Some limitations on the use of certain datatypes

Logical standby database problem

i have setup logical standby database on my pc . Everything was working fine . Logs were applied.
But i tried testing few things on standby and issued few commands on that.
After that the logs were not applied. i tried to restart that also dint work.
what should i do so that things r back to normal or i need to create the standby again .
Thanks

The output is as follows .
SQL> SELECT APPLIED_SCN, NEWEST_SCN, READ_SCN, NEWEST_SCN-APPLIED_SCN FROM DBA_LOGSTDBY_PROGRESS;

Logical standby database

Guys,
Is it possible to create a logical standby database without installing Oracle Data Guard.And if yes how sync. is performed.
Thanks

Hi,
Is it possible to create a logical standby database without installing Oracle Data Guard.In a sense Oracle Streams and Quest Shareplex created a logical standby, but you can have them open too . . . Madhu Tumma explains this in his Oracle Streams book, but it's only conceptually similar to logical standby in Data Guard:
http://www.rampant-books.com/book_2004_2_streams.htm
Hope this helps. . .

Logical standby database SE

In the past we creating and maintaining physical standby database in SE (without DataGuard, via scripts).
Is possible create and maintain LOGICAL standby database in SE without DataGard (any example are welcome!)
Thanks in advance!
Diego.

According to Metalink Note:271886.1
"Message queuing and apply features of Oracle Streams are available in Standard Edition and Standard Edition One, but change capture is available only in Enterprise Edition."

Logical standby database to physical standby database

I already start my logical standby database and I want to return it again to physical standby database. So what should I do?
