Logical Standby working issues Oracle 9i, Windows

Hi,
Set up Oracle 9i Logical Standby on Windows. (instructions as per Oracle Documentation)
Did not have any issues setting up.
While setting up the Logical Standby, Recovered the Primary Database until Oct 10/09 8:16 pm
Registered the archive log in the logical standby generated hence and the FAL took care of copying/registering the rest of the archivelogs.
Created and inserted some records in Primary database and could see them in Standby.
So far so good.
On Oct11 data was entered into Primary database. Archivelogs were shipped to Standby, I could see them registered in DBA_LOGSTDBY_LOG.
The APPLIED_SCN,NEWEST_SCN were in sync as per DBA_LOGSTDBY_PROGRESS.
Today, we had some issues with data and when we queried the user tables: (no skip settings)
Couldn't see any data in standby past the recovery...
No errors reported in DBA_LOGSTDBY_EVENTS. No errors in Alert log also.
What could be happening?
Thanks,
Madhuri

I figured it out...
Today, we had some issues with data and when we queried the user tables: (no skip settings)
Couldn't see any data in standby past the recovery...I was using two tables as random spot check and both did not get updated. So, I was under the impression SQL APPLY did not do anything.
But, it did apply the redo on the rest of the tables.
These 2 tables in question were skipped because both of them had Function Based indexes.
They are very huge individual tables .
So, exporting them from Primary database and Importing them into Standby Database. Skipping DML in DataGuard.
That solved the problem.

Create an Object in Logical standby database in Oracle 10G

Hi,
I have logical standby database in oracle 10g R2 for reporting purpose.Now i want to create procedure in logical standby which is use to create new temp table in logical standby and contained data generated from select operation on existing table.
Can i create a new user in logical standby database,add new tablespace in logical standby which can insert,update and delete data in standby database base table?
kindly provide me the steps to implement all this.What will be effect if i set guard_Status in v$database is NONE in logical standby?
Thanks,
Shital Patel

Hi Shital,
Guard_status protects the data from being changed.
ALL- By default it is not possible for a non-privileged user to modify data on a data guard SQL apply database. This is because the database guard is automatically set to ALL.
With this level of security, only SYS user can modify the data.
STANDBY- When you set this level of security, users are able to modify data that is not maintained by the Logical apply engine.
NONE permits any users to access the standby database as long as they have correct privileges. This is the normal security for all data in the database.
You can change the guard status value from ALL to NONE in order to allow non-privileged users to modify data and Yes you can create user and extra tablespace in logical standby database..this is what the one of advantage of using Logical standby database.
SQL> ALTER DATABASE GUARD NONE;
Thanks

Logical standby database issue?

Hi,
I created a logical standby database on the same server as primary database.
then I transited the old primary DB to standby DB,
old standby DB to primary DB.
and "alter system switch logfile" in new Primary DB.
execute sql in new standby DB:
SQL> SELECT APPLIED_SCN, NEWEST_SCN FROM DBA_LOGSTDBY_PROGRESS;
APPLIED_SCN NEWEST_SCN
0
question:
the redo logs can not be applied to new standby DB,
How to solve it?
thanks
DB release:9i

Hi,
Can you upload the output of:
sqlplus> show parameter arc
from both instances, or post the init.ora parameters from both. I would like to verify your arc related parameters.
Also, did you check the alert log in the primary and standby for errors?
Thanks,
Idan.

We have tried to apply note 1442501 but we still get the error. We have upgrade all our landscape without any issue, of course this issue is in our production system. If you have any suggestions, that would be great.
Thanks
Jean Seguin

Hi Jean,
Did you delete the table KMC_WF_SUBSTITUTE from the database directly and retry the update?
Also try updating only the UWLJWF first after dropping the table, as suggested in the blog:

Apply Patches on Oracle Database with Logical Standby Database

Here I am:
I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.
I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?
1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site
Thanks in advance.

Plz rply ASAP

Here are the steps to identify the object in question:
1) Start the replication on logical standby
2) Once the replication starts it will show you the same error in the alert log file as you mentioned above.
3) Query DBA_LOGSTDBY_EVENTS order by EVENT_TIMESTAMP. The last event will capture the name of the object that is creating the problem.
4) Based on your knowledge of database /application objects, you can skip that table using DBMS_LOGSTADBY.SKIP and start the replication again without any issue.
5) If you dont need that object in the logical DB to be replicated then let it be skipped, otherwise reinstate the object again in logical standby.

Logical Standby Problem

My environment is Primary database is 11.1.0.7 64bit on Windows 2003 Enterprise 64bit. Logical is on the same platform and oracle version but a different server. I created a physical standby first and it applied the logs quickly without any issues. I received no errors when I changed it over to a Logical standby database. The problem that is happening is as soon as I issue the command "alter database start logical standby apply;" the CPU usage goes to 100% and the SQL apply takes a long time to apply a log. When I was doing this on 10G I never ran into this, as soon as the log was received, it was applied within a couple of minutes. I don't think it could be a memory issue since there is plenty on the Logical standby server. I just can't figure out why the SQL apply is so slow and the CPU usage skyrockets. I went through all of the steps in the guide "Managing a Logical Standby Database" from Oracle and I don't see anything wrong. The only difference between the two databases is that on the Primary I have Large Page support enabled, I don't on the Logical. Any help would be greatly appreciated, I need to use this Logical to report off of.

Thanks for the responses. I have found what is causing the problem. I kept noticing that the statements it was slowing down on were the ones where data was being written to the SYS.AUD$ table in the System tablespace on the Logical Standby database. A quick count of the records showed that I had almost 6 million records in that table. After I decided to truncate SYS.AUD$ on the Logical, the archive logs started to apply normally. I wonder why the Logical has a problem with this table and the Primary doesn't. I didn't even know auditing was turned on on the Primary database, it must be enabled by default. Now I know why my System table space has grown from 1gb to 2gb since November.
Now that I fixed it for now, I am unsure what to do to keep this from happening. Can I turn off Auditing on the Logical and keep it on for the Primary? Would this stop data from being written to the SYS.AUD$ table on the Logical? It doesn't appear that there is any kind of cleanup on this table that is offered by Oracle, I guess I can just clean out this table occasionally but that is just another thing to add to the list of maintenance tasks. I notice that you can also write this audit data to a file on the OS. Has anyone here done that?

Logical standby stops deleting archives automatically

We are ruining 11.1.0.7 on windows 2008 64 bit
The issue I am facing is we have these settings implemented
log_auto_delete = true
log_auto_delete_retention_target = 5
Logical standby works fine and deletes the archive logs coming from primary but after some day it stops working. I have to stop and start the database in order to make it work. Does anybody has this kind of situation? Please help.

Hello;
This might be worth a look:

Logical Standby SQL Apply Using Incorrect Decode Statement

We are seeing statements erroring out on our logical standby that have been rewritten (presumably by sql apply) with decode statements that don't appear to be correct. For example, here is one of the rewritten statements.
update /*+ streams restrict_all_ref_cons */ "CADPROD"."OMS_SQL_STATEMENT" p
set *"APPLICATION"=decode(:1,'N',"APPLICATION",:2)*,
"STATEMENT"=dbms_reputil2.get_final_lob(:3,"STATEMENT",:4)
where (:5='N' or(1=1 and (:6='N' or(dbms_lob.compare(:7,"STATEMENT")=0)or(:7 is null and "STATEMENT" is null)))) and(:8="APPLICATION")
The problem comes in, we believe, with the attempt to write the value "APPLICATION" to the application column which is only a 10 character field. the value for the :1 bind variable is "N" and the value for :2 is null.
We see the following error on the logical standby:
ORA-00600: internal error code, arguments: [kgh_heap_sizes:ds], [0x01FCDBE60], [], [], [], [], [], []
ORA-07445: exception encountered: core dump [ACCESS_VIOLATION] [kxtoedu+54] [PC:0x2542308] [ADDR:0xFFFFFFFFFFFFFFFF] [UNABLE_TO_READ] []
ORA-12899: value too large for column "CADPROD"."OMS_SQL_STATEMENT"."APPLICATION" (actual: 19576, maximum: 10)
Is this a configuration issue or is it normal for SQL Apply to convert statements from logminer into decode statements?
We have an Oracle 10.2.0.4 database running on windows 2003 R2 64-bit os. We have 3 physical and 2 logical standby's, no problems on the physical standbys.

Hello;
I noticed some of your parameters seem to be wrong.
fal_client - This is Obsolete in 11.2
You have db_name='test' on the Standby, it should be 'asadmin'
fal_server=test is set like this on the standby, it should be 'asadmin'
I might consider changing VALID_FOR to this :
VALID_FOR=(ONLINE_LOGFILES,ALL_ROLES)Would review 4.2 Step-by-Step Instructions for Creating a Logical Standby Database of Oracle Document E10700-02
Document 278371.1 is showing its age in my humble opinion.
-----Wait on this until you fix your parameters----------------------
Try restarting the SQL Apply
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATEI don't see the parameter MAX_SERVERS, try setting it to 8 times the number of cores.
Use these statements to trouble shoot :
SELECT NAME, VALUE, UNIT FROM V$DATAGUARD_STATS;
SELECT NAME, VALUE FROM V$LOGSTDBY_STATS WHERE NAME LIKE ;TRANSACTIONS%';
SELECT COUNT(1) AS IDLE_PREPARERS FROM V$LOGSTDBY_PROCESS WHERE

Real-time apply cascaded logical standby database

Hi
I have a primary database orcl
Pysical standby database orcl_std
Cascaded logical standby database orcl_tri which receives archivelogs from orcl_std
Real time apply is enabled both in orcl_std (physical standby) and orcl_tri (logical standby)
When I create a table in primary orcl, I am unable to see it on orcl_tri (Although real time apply is enabled)
However, when I switch log in primary, I can see the new table on orcl_tri.
My question is, why realtime apply is not working in my scenerio ?

Hi mseberg,
Thanks for your reply.
There is no load or network issue as I`ve just created these databases for the experiement.
I have the same output from standby and primary databases.

Logical standby stuck at initializing SQL apply only coordinator process up

Hi
OS: solaris 5.10
Hardware: sun sparc
Oracle database: 11.2.0.1.0
Primary database name: asadmin
Standby database name: test
I had been trying to convert a physical standby to logical standby database. Both the primary and standby reside on the same machine.
The physical standby was created with a hot backup of primary.
I had been following document id 278371.1 to convert the physical to logical standby and used the following steps:
Relevant init parameters on primary:
*.db_name='asadmin'
*.db_unique_name='asadmin'
*.log_archive_config='dg_config=(asadmin,test)'
*.log_archive_dest_1='location=/u01/asadmin/archive valid_for=(all_logfiles,all_roles) db_unique_name=asadmin'
*.log_archive_dest_2='SERVICE=test async valid_for=(online_logfiles,primary_role) db_unique_name=test'
*.log_archive_dest_state_1='enable'
*.log_archive_dest_state_2='enable'
*.fal_client='asadmin'
*.fal_server='test'
*.remote_login_passwordfile='EXCLUSIVE'
Relevant init parameters on standby database:
*.db_name='test' -- Was asadmin before I renamed the DB during conversion to logical standby
*.db_unique_name='test'
*.log_archive_dest_1='location=/u01/test/archive valid_for=(all_logfiles,all_roles) db_unique_name=test'
*.log_archive_dest_2='service=asadmin async valid_for=(online_logfiles,primary_role) db_unique_name=asadmin'
*.log_archive_dest_state_1=enable
*.log_archive_dest_state_2=defer
*.remote_login_passwordfile='EXCLUSIVE'*.fal_server=test
*.fal_client=asadmin
Steps on primary:
1) alter system set log_archive_dest_state_2=defer;
2) shutdown immediate;
3) Made sure that the physical standby has applied all of the redo sent to it following the shutdown.
4) startup mount;
5) ALTER DATABASE BACKUP CONTROLFILE to '/home/oracle/control01.ctl';
6) ALTER SYSTEM ENABLE RESTRICTED SESSION;
7) ALTER DATABASE OPEN;
8) Verified that the supplemental logging is on.
9) ALTER SYSTEM ARCHIVE LOG CURRENT;
10) Checked for the checkpoint change no. at this point which is 72403818 and is present in archive log file 1_62_775102253.dbf
11) EXECUTE DBMS_LOGSTDBY.BUILD;
12) ALTER SYSTEM ARCHIVE LOG CURRENT;
13) Checked for the archive log containing dictionary build which is 1_64_775102253.dbf
14) ALTER SYSTEM DISABLE RESTRICTED SESSION;
Details of archive logs and related checkpoint change nos:
NAME FIRST_CHANGE# NEXT_CHANGE#
/u01/asadmin/archive/1_61_775102253.dbf 72402901 72403817
/u01/asadmin/archive/1_62_775102253.dbf 72403817 72404069
/u01/asadmin/archive/1_63_775102253.dbf 72404069 72404211
/u01/asadmin/archive/1_64_775102253.dbf 72404211 72405700
Steps on standby:
1) shutdown immediate;
2) Copy the archivelog file 61(was created at primary after apply stopped at standby), 62(contains checkpoint no. 72403818), 63 and 64(contains dictionary build). Copy the backup controlfile from step 5 above to the controlfile location in standby init.
3) startup mount;
4) Rename all datafiles and redo log files (including standby redo log files) to the correct path on standby.
5) alter database recover automatic from '/u01/test/archive' until change 72405700 using backup controlfile; -- This completed error-free

I also greped for lsp and lcr processes and found that lsp is up but do not see any lcr.
The logs are getting transported to the archive destination on standby whenever they are archived on primary but are not getting applied to standby.
Also in case the standby is down while a log is generated on primary it is not automatically transported to standby once the standby is up, means gap resolution is also not working.
I see the following in alert log every time I try to restart the log apply, everything seems to be stuck at initialization.

Hello;
I noticed some of your parameters seem to be wrong.
fal_client - This is Obsolete in 11.2
You have db_name='test' on the Standby, it should be 'asadmin'
fal_server=test is set like this on the standby, it should be 'asadmin'
I might consider changing VALID_FOR to this :
VALID_FOR=(ONLINE_LOGFILES,ALL_ROLES)Would review 4.2 Step-by-Step Instructions for Creating a Logical Standby Database of Oracle Document E10700-02
Document 278371.1 is showing its age in my humble opinion.
-----Wait on this until you fix your parameters----------------------
Try restarting the SQL Apply
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATEI don't see the parameter MAX_SERVERS, try setting it to 8 times the number of cores.
Use these statements to trouble shoot :
SELECT NAME, VALUE, UNIT FROM V$DATAGUARD_STATS;
SELECT NAME, VALUE FROM V$LOGSTDBY_STATS WHERE NAME LIKE ;TRANSACTIONS%';
SELECT COUNT(1) AS IDLE_PREPARERS FROM V$LOGSTDBY_PROCESS WHERE
TYPE = 'PREPERER' AND STATUS_CODE = 16166;Best Regards

Procedure for creating logical standyby database for oracle 11g?

Hi all,
can anybody provide me docs /procedure for creating logical standby databse for oracle 11g standard edition.
Aravind

Aravind,
1. The Oracle Standard Edition does not have standby mechanism, you should do it manually or go for Enterprise Edition.
2. It's rather a question for General Database Discussions instead of Peoplesoft.
Any further question regarding that point, please post out there.
Nicolas.

Physical Standby database Vs. Logical Standby database

I have few questions regarding capability of Logical Standby Database against Physical Standby database.
1. How efficient is Logical Standby database in terms of Physical Standby Database?? How both differ from each other and can I use Logical Standby Database for disaster Recovery?? Can It be use for recovering the failed Primary Instance?? If yes how efficient and reliable it is??
2. What are the known bugs and roadblocks for logical standby database on Oracle 10.2.0.1 on Soalris X86-64?
3.As logical standby database not going to replicate each and every schema of Primary database?? how is the change management effects to the logical standby from primary?? I mean there are some parameters and job that we create on primary how can it be transferred over to the logical standby??

1. How efficient is Logical Standby database in terms
of Physical Standby Database?? How both differ from
each other and can I use Logical Standby Database for
disaster Recovery?? Can It be use for recovering the
failed Primary Instance?? If yes how efficient and
reliable it is??I'm not sure what sort of "efficiency" you're talking about here...
Physical standby is just the old, tried and true application of archived logs to recover a database. Very solid, very old school.
Logical standby, on the other hand, is parsing the redo log, extracting logical change records, and applying them to the standby database. This obviously takes a bit more processing effort, it's newer technology, it doesn't have quite the level of support that physical standby does (i.e. certain data types are excluded), etc. You certainly can use it for failover, but it isn't quite as robust as a physical standby. Of course, this is getting better and better all the time and is definitely a focus of Oracle's development efforts.
On the other hand, logical standby systems can do things other than act as a warm standby. They can be open serving reports, for example. You can create additional structures (i.e. new materialized views) to support reporting. A physical standby is pretty much always going to be in managed recovery mode, so it cannot be queried.
2. What are the known bugs and roadblocks for logical
standby database on Oracle 10.2.0.1 on Soalris
X86-64?a) You'll want to do a Metalink search
b) If you're talking about a high-availability solution, why are you looking at a base release of the database? Why wouldn't you apply the latest patchset?
3.As logical standby database not going to replicate
each and every schema of Primary database?? how is
the change management effects to the logical standby
from primary?? I mean there are some parameters and
job that we create on primary how can it be
transferred over to the logical standby??I'm not sure I understand... Changes made to the primary generate redo. Oracle parses that redo, generates a LCR, and sends that to the standby database where that change record gets applied.

Error when logical standby database

Hii all,
First time i am creating logical standby database on oracle 10gR2 by oracle doc.
