Logical Standby / Streams?
Feb 3, 2012Source DB is logical standby 10.2.0.5
Destination DB is 11.2.0.3
Is it possible to set up streams on the logical DB to replicate some schemas to the 11gR2 DB?

Data Guard :: Possible To Convert Logical Standby To Physical Standby
Aug 30, 2013My steps for testing as below:
1.create a primary database
2.duplicate a physical standby database;
3.turn on flashback on both databases.
4.record SCN xxx on physical standby database.
5.convert physical standby to logical standby (using keep identity statement)
6.flashback to logical standby to xxx
7.convert logical standby to physical standby
8.using real time apply I got errors: Fast Parallel Media Recovery enabledManaged Standby Recovery starting Real Time ApplyMRP0:

Creating MV Logs In Logical Standby DB?
Dec 10, 2010I am trying to create materialized views based on a few tables in a logical standby database.
The target database (11g R2) where the MVs will be created is a stand-alone database.
The DB where the base tables reside is a logical standby database (11g R2).
The requirement is to do a "FAST REFRESH" of the Materialized Views.
My questions are :
1. Can I create MV logs in the logical standby DB?
2. If the answer to question no. 1 is "Yes", do I need to do anything different or configure the logical standby DB in a specific manner in order to create MV logs. From what I understand, the objects in the logical standby database are in a locked state.

Real Time Apply For Logical Standby
Nov 15, 2012Oracle 11.2.0.3.0
I have a primary database orcl and logical standby database orcl_std.
Real time apply is enabled. I have standby redologs in both primary and standby sides and I`ve started recovery with below command:
ALTER DATABASE START LOGICAL STANDBY APPLY IMMEDIATE;
When I create a new table in primary database, I am unable to see it on standby database (Although real time apply is enabled) However, when I switch log in primary, I can see the new table in standby database.
My question is, why realtime apply is not working in my scenerio ? I was expecting to see the new table immediately in standby database once it is created in primary database. Why am I supposed to wait for log switch in real time apply ?
Recovery Manager (RMAN) :: Physical And Logical Standby?
Aug 29, 2013,I have a test environment with Primary DB Server, Physical Standby and Logical Standby.The Logical Standby DB (cur_log_stdb) is backed up every evening by RMAN and I have a question:If I recover my Logical Standby DB from backup and switch replication to new Logical Standby DB (new_log_stdb) it will work or not?My steps e.g.:1. Make a new server for my new_log_stdb and repair structure of catalogs;2. Repair listener.ora and tnsnames.ora files from cur_log_stdb to new_log_stdb;3.
Restore DB with RMAN from backup to new_log_stdb;4. On cur_log_stdb execute "alter database stop logical standby apply";5. Change a DNS name from cur_log_stdb to new_log_stdb;6. On new_log_stdb execute "alter database start logical standby apply immediate";I'm not sure that archivelogs will apply to the new_log_stdb for period since rman backup was created.

Data Guard :: Apply Patches On Oracle Database With Logical Standby Database?
Apr 22, 2011I 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

Data Guard :: Apply Standby Redo Log To Physical Standby Database
May 26, 2013I have dataguard configuration operating in maximum availability mode with a local standby db (A - lgwr sync not using real time apply) and a remote standby db (B - lgwr async). I then simualted a crash of my primary database with batch jobs running. Since the stby db A is in lgwr sync option ,all the commited data in the current online redo log has been transmitted to stby A and is present in its stby redo log (Group 2).How do I apply this stby redo log to the remote stby db.
Tried the following methods.
1.ftp the stby redo log to the remote db and tried to regiter it, got an error that it is not completely archived.
2.issued the recover standby database command and supplied the stby redo log when it asked for the sequence in the stby redo, got an error saying there is corruption in a block(tried this option multiple times ended up with the same result.)

Oracle Streams 11g (11.1.0.7) - Getting Error?
Oct 4, 2010Platform: Windows 2003
Streams Set up: One way Streaming at table level
The error: ORA-26786: A row with key ("REPT_NUM", "STATE_CODE", "SURVEY_ID") = (067305669, 49, J) exists but has conflicting column(s) "DATE_TIME", "PREV_PARENT_ID" in table TOPCATI_JOLTS.UNIT ORA-01403: no data found
We are consistently getting this error every other day and some weeks more often, different records of course. On the capture site the application does a process called split cases. In this process the application will take an old PK case num insert a new PK case number with all of the data of the old case (Parent level). At the unit (Child level) the application will change all of the units to this new FK case number. This means the old case (parent) is left with no child units. This is all one transaction.
Is it possible that streams may be applying the LCR's out of order? especially since that whole process is one transaction.
Oracle Streams 11g Not Working?
Mar 26, 2013I am trying to setup a one way queue that will be consumed by an inhouse ESB.We currently are able to create a multi-consumer queue using:
CODEBEGIN
DBMS_STREAMS_ADM.SET_UP_QUEUE(queue_table => 'strmadmin.streams_queue_table',
queue_name => 'strmadmin.streams_queue');
END;
but unfortunatly the ESB that we are using uses a jms component which seems to only be able to take mono-consumer queue.So we have created our queue usuing the following
CODEBEGIN
DBMS_AQADM.CREATE_QUEUE_TABLE( Queue_table => '"STRMADMIN"."STREAMS_QUEUE_TABLE"',
Queue_payload_type => 'SYS.ANYDATA',
storage_clause => 'PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 TABLESPACE
[code]...
This therefore permits us to have a queue/queuetable which pushes data to a single consumer.The probleme comes when we try to add a table rule using the following command:
CODEBEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES( table_name => 'source.t1',
streams_type => 'apply',
streams_name => 'streams_apply',
queue_name => 'strmadmin.streams_queue',
[code]...
We then get the following error:
CODEORA-06512: on line 2 24039. 00000 - "Queue %s not created in queue table for multiple consumers"
*Cause: Either an ADD_SUBSCRIBER, ALTER_SUBSCRIBER, or REMOVE_SUBSCRIBER procedure, or an ENQUEUE with a non-empty recipient list, was issued on a queue that was not created for multiple consumers.
*Action: Create the queue in a queue table that was created for multiple consumers and retry the call.
We are able to create the capture rule without any problem but without the apply rule, nothing seems to end up into the queue table.AQ is not a viable solution since it is troublesome when it comes to deletes and mass updates.
Streams :: Synchronizing Tables In Two Different DB

Finding Missing Archived Log For Streams
Mar 2, 2012i'm trying to write a pl/sql to find all missing archived logs that are need for streams replication.
There is already a oracle metalink note for this. But yet it would give only the archive log name that contains my dba_capture.start_scn and we need to check if the files exist in disk or not!
The problem here is, when using ASM, dba_registered_archived_log view is truncation the file name and it is really difficult to pin point the logs. So is it fine to join this view with V$archived_log? is deleted and status column would do the trick? I modified the plsql as below. Is this fine/accurate?
CODEdbms_output.put_line('Capture will restart from SCN ' || lScn ||' in the following file:');
for cr in
(select decode (a.name, NULL, 'NOT FOUND', a.name) name, to_char(a.completion_time, 'hh42:mi:ss') completion_time from v$archived_log a,dba_registered_archived_log b where lscn between b.first_scn and b.next_scn
and a.deleted = 'YES' and a.status != 'A')
loop
f_rec :=1;

ORA-26713 Streams Apply Error And Gateway
Mar 27, 2013My setup is following:
CODEhost22 (Oracle Linux 5.9) | host30 (Windows XP) with SQL Server Express 2008
DB22 | Gateway to MSSQL | DB30
Local Local | |
Capture --> Apply ------> Gateway -----------------> DUMMYUSR.DUMMYTBL
Process Process | |
Capture process on DB22 captures changes made to local DUMMYUSR.DUMMYTBL table, enqueues it to capture queue and propagates to apply queue for local apply process, which, using database link DB30 supposed to apply these changes to table DUMMYUSR.DUMMYTBL on remote SQL Server database DB30.
The problem is that when apply process is executing transaction, it aborts with error:
QUOTE ORA-26713: remote object does not exists or is inaccessible.
ORA-26712: remote object is "DUMMYUSR"."DUMMYTBL"@"DB30".
In trace log I can see the following message:
QUOTE kniNoPrimaryKeyError: ORA-26713, remote obj doesn't exist,
DUMMYUSR.DUMMYTBL@DB30
[code]...
what can cause ORA-26713 error of apply process applying changes to SQL Server database through Oracle Database Gateway, if object to be modifyed exists and accessible from Oracle database for strmadmin user?
By the way, database link and tables were created with following commands: CODEDB22(Oracle): (connected as strmadmin) create database link DB30 connect to "dummyusr" identified by "dummypwd" using 'DB30';
DB22(Oracle): (connected as dummyusr)

Using Total Recall With Streams - Reporting Database?
Jun 2, 2010this Topic was already discussed in "Physical standby on oracle 11g - Reporting needs" but without finishing.
View 5 Replies View RelatedReplication :: Oracle Streams Or MVs Or Database Triggers
May 27, 2011We have three unix servers with four databases (10gR2) containing "HP Operation Management Unix" (OMU) server messages for monitoring purpose, and we now want to transfer these data to one new database on a new server for reporting purpose.
The message table in each OMU database keeps the message row until it is "Acknowledged" or for maximum fourteen days, then it is moved to an historic table where it stays for another three days. Keeping data for only seventeen days are a performance issue.The new "Reporting database" is intended to hold messages data for the last 90 days.
I wonder which method to use to move/replicate data against the databases? Materialized view using database link, with view on top of the MVs. How to keep rows longer than the master (source) table, avoiding deletion when master row is deleted
Oracle Streams, with local capture and remote apply. How will this influence on the master database performance. There are about 10000 new messages in each OMU database every day. Is it possible having four streams connections against the reporting database ?
Or should I simply use database triggers which fires after insert and update and applies changes to the reporting database using database links ?
