Logical standby setup

Hi,
i'm configuring logical standby database,after giving alter database start logical standby apply; database was altered.
but select name, value
from v$logstdby_stats
where name = 'coordinator state' 2 3 ;
is not showing the status applying .how much will it take to come to applying status.
SQL> alter database start logical standby apply;

Dataguard - logical standby - need help - not updating data at commit

Hi
Need help ?
We have logical standby setup where data is not updated at standby when committed at Primary. It only updates when alter system swith logfile.
On Primary:
log_archive_dest_2='service=xxStandby LGWR ASYNC valid_for=(online_logfiles,primary_role) db_unique_name=xxStandby'
On Standby:
we have already created standby redo logs ( 1+ # redo logs)
we used ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE NODELAY;
The data only ships when we do the ALTER SYSTEM SWITCH LOGFILE whereas it should so when data is commited on the primary.
Is there anything we are missing or need attention.
Please help
Thanks you so much

Yes, I have standby redo logs = ( 1 + # redo logs on the primary) and are of same size.
I also changed the log_archive_dest_2 setting for valid_for to ALL_LOGFILES, but the performance is still very slow... we are now overr 9 hrs behind the primary.
log_archive_dest_2='service=xxStandby LGWR ASYNC valid_for=(ALL_LOGFILES,primary_role) db_unique_name=xxStandby'
The Logical standby performance reallly not good at all. trying to increase sga/pga more ... hoping this will speed up some

Oracle DataGuard Logical Standby

Hi , I'd like to know what are the premisses to make a standby logical replication.
I have two environments (production and standby) with different number of processors and storage.
I'd like to know if it's possible to create data guard solution with these two environments and what are the premisses that I need aware to install the solution.
Thanks in advance.

Hello;
Yes the storage ( as long as you have enough space ) and cpu don't matter.
You can use hardware that's quite a bit different and it will work fine.
You can also create a Logical Standby fro a physical standby.
These notes may help :
NOTE 413484.1 - Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration
Mixed Oracle Version support with Data Guard Redo Transport Services [ID 785347.1]
Logical Standby's don't seem to be very popular and the support base suffers because of this. I would consider a physical standby with Active Data Guard if costs allow.
Active Data Guard makes an excellent "Reader" database plus I believe your switchover and failover options are much better than a Logical Standby.

Best Way to setup a disaster Recovery site for a logical standby database

I have a logical standby DB (L1DB) as a reporting db on the same machine as the primary (P1DB). We are planning on building a disaster recovery site with similar hardware and potentially have disk mirroring of atleast the redo log files.
The DR site can hold an additional physical standby (S1DB) for the primary (P1DB). I am trying to understand what would be the best way to setup the Disaster Recovery site for the L1DB logical stdby. Ideally, when the disaster happens, and I no longer have P1DB and L1DB, I should be able to switch to S1DB as the new primary. But how do I setup to have a L2DB that takes the place of L1DB and has its contents and can be setup as a logical standby of S1DB?

If you already setup one logical standby, then you know how it works, so not sure what question you are asking ?
Personally I would setup L2DB as a standby of the original primary P1DB. Having downstream standby databases complicates things, and adds additional lag between primary transaction time and L2DB 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.

Error while Creating a Logical Standby Database

Dears
I setup physical standby db. Now trying to convert it to logical standby db by following this link:
http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ls.htm#i92346
When i issue this statement:
ALTER DATABASE RECOVER TO LOGICAL STANDBY orcl2;
I am getting following error:
ORA-00905: missing keyword.
I do not find anything in ALERT.LOG file. The syntax seems to be correct as i carefully copied from the document itself.
Please reply.

Any ideas?

ORA-01403 - Logical Standby Apply ends on delete/update statement

- This thread is relocated to this forum; advice from Daniel Roy -
After implementing 2 logical standby databases and running pretty smooth for a while 'strange' errors occur which puzzle me. Sometimes I skip a transaction or exclude a schema from replication and hold my breath for what next roars its ugly head.
Despite fulfilling all logical standby prerequisites and maintaining primary keys on tables I now run into ORA-01403 errors. The updated table only contains 1 row and has a foreign key to another small table.
I could instantiate these tables, but I want to understand why these errors occur and prevent them form happing or learn how to resolve them best.
Anyone around who dealt with these matters and won?
I'm running this implementation with Oracle 9.2.0.7 on Tru64 51.b
I'm able to create the logical standby databases manually and with aid of the Data Guard Creation Wizard (EM10g 10.1).
Can anyone also help me out with refining the faulty transaction from e.g. V$LOGMNR_CONTENTS? (Without disrupting the data guard setup).
I've already retrieved redo info from archivelogs, but there must be an easy way.
Regards,
Erik

Any way for you to turn tracing on for the DB where you see this ORA-01403 error? We could then probably find out exactly what goes wrong. It's very hard for us to know exactly what might be wrong, since we don't know your exact setup (except for this table). Let me know if that's not possible, and I could construct a logical DB setup to test (even tho it would be on Windows, I don't have Tru64).

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

Logical standby DB with unsupported datatype

Hello,
Has anyone setup the following Data Guard Configuration, although it is not recommended by Oracle:-
Setup a logical standby DB from a Primary DB with unsupported Data Types. I'm need (and want) to save time and effort to configure a database for the purpose of Reporting and avoid Oracle Streams or Change Data Capture or even the new middleware Product Data Integrator
Data is sent from the Productive DB, and with logical standby DB, I (hope) can still get it to run even with unsupported data types using DBMS_LOGSTDBY.SKIP procedure, to skip unwanted and unsupported attributes in the primary DB.
I would appreciate any comments and experience using Logical Standby DB for Reporting Purposes.
regards
Sahba

Hello Anantha,
thanks for your reply.
unfortunately the Productive database uses dartatypes such as DMSYS.SDO_GEOMERTY.
these datatypes are not supported by the Logical standby DB.
I thought, i could skip those tables with such datatypes when applying redodata in the logical standby db, dbms_logstdby.skip procedure allow such mechanism.
the reason why i need logical stndby db ist due to READ/WRITE during apply process. as I mentioned, i need an up-to-date replica of the productive db for reporting purposes, without such tables with unsupported datatpes. because these are tables are not part of the reporting procedure, i thought of skipping them from appling in logical stndby db .
so, has anyone have had any complications with Logical stndby db even when using dbms_logstdby.skip procedure?
are there any other problems encountered with logical stndby db to share here?
thanks
regards
Sahba

Please any comments, help or suggestions would be great..
Thanks - HP

Appreciate your kind reply Robert..
Would it be the only option left for me to re instantiate the logical standby..? Or what if i enable flashback on logical standby and then try to flashback till "standby_became_primary_scn" and then try to start logical standby apply.. Will this work in my scenario?
Any suggestions or comments are most welcome.

NEED HELP!!!! Logical Standby and RMAN.

Hello,
I have a Data Guard env setup on win 2000 with 9.2.0.4.
I now have primary and standby. I was wondering if I create a logical standby to achieve transparent application failover. What I am saying is if the primary node dies, then in tnsnames I want to point to the logical standby, since it is an open database, the users can still perform without knowing the db went down. Then if we indeed need a failover we can failover to the physical standby. This would ensure availability without having to implement RAC or AQ, Right? Also, I read that you should create rman schema (recovery catalog) on standby db. Any thoughts?

Were you able to figure this one out?
I have a similar configuration as you - the same motherboard and an eVga Geforce 3 6600 fanless. With the latest BIOS (3.8) and this video card, the system will not go into Standby completely. I hear the HDD head park and the video goes black, but the LEDs on the front of the PC chassis and the case/PS fans do not stop. Pressing the button to bring the PC out of Standby, rather, whatever state it is in, works.

Configuration of the Physical & Logical standby servers on the same machine

I've encoutered a problem to connect to one of the standby servers .
I created a DataGuard in 10.2. Primary on 1 machine, 1 physical standby and 1 logical standby on another machine (both phy and logical in same machine)
I first created a primary then a physical standby. I've got no problem at all.
But when I created a logical standby server on the same machine with the physical then I could not connect to both phy and logical . I can connect to either one of them.
According to DataGuard setup, the db_name must be the same in primary and all standby servers. This is fine when each of the primary or the standby installed in a separate machine.
The db_name of the physical = rolex
The db_name of the logical = rolex
When we have more than one instance in the same machine, we just set the ORACLE_SID = db_name ( or instance), then connect to it.
If I connect to the physical, then I try to connect to the logical, it goes to the physical or vice versus.
Does anyone have the solution ?
QN

DB_UNIQUE_NAME parameter will be the seperator.
give DB_UNIQUE_NAME parameters different names and set ORACLE_SID with DB_UNIQUE_NAME name you gave
DB_NAME is the primary instances database name DB_UNIQUE_NAME is given for standby instances database name
