Duplicate sequence# in standby

Hi all,
10.2.0.1
With this query in the standby database,I am finding duplicate sequence#s.
SQL> select sequence#,first_time,next_time from v$archived_log;
12473 21-JAN-10 21-JAN-10 NO
12473 21-JAN-10 21-JAN-10 YESIt seems its a bug otherwise what could be the reason for this anomaly?
Thanks

Does the refrence guide mean that when log arrived,its applied status is no so one entry for that and when applied its status is yes so another entry for that. Then why not the same for sequence# 12474 and below?
Thanks

Stop duplicate sequence with exception

I created a table that uses two sequences. I recently discovered that some of these sequence values being generated were either skipped or duplicated when added to the table.
At first I did not know why the sequence values in the table were being skipped or duplicated luckily I found an article, http://www.arikaplan.com/oracle/ari82599.html. I have now made the correct changes to diminish this effect.
So my goal right now is to figure out how to insert the skipped sequence back into my table whenever a new row is created without adding duplicate sequence for the "id" column.
This is what I have so far:
create sequence global_key INCREMENT BY 1 START WITH 1 MINVALUE 0
NOCYCLE nocache;
create sequence global_ids INCREMENT BY 1 START WITH 1 MINVALUE 0
NOCYCLE nocache;
create table ids (
key varchar2(100) primary key,
id number(20)
CREATE OR REPLACE TRIGGER global_key_trigger
BEFORE INSERT
ON ids
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
begin
select global_key.NEXTVAL into :new.key from dual;
end;
declare
res number(20);
begin
select global_ids.nextval into res from dual;
     select id into res
from ids
where id = res ;
end;
     exception
     when no_data_found then return res -- ??;
     when DUP_VAL_ON_INDEX then -- continue loop ??
end;
Thank you

Error while duplicate database for standby

Hello Guys,
Both of my database are 10gR2 and Linux is the operating system.
I am trying to create a standby database for my production database.
I have matched the directory structure of primary and standby database and there is no conflict. Directory permissions are also set.
After taking the rman backup from production database when i connect auxiliary database from production. I run this command to duplicate database and create standby database.
rman

Hi,
Permissions Issue on STANDBY machine?First problem I see is the sysdba password must be the same on both sides (target and auxiliary dbs).
From the documentation.
The source database and auxiliary instances must use the same SYSDBA password, which means that both instances must have password files. You can
create the password file with a single password so you can start the auxiliary instance and enable the source database to connect to it.Check all prereqs for the standby db duplicate here.

Duplicate database FOR STANDBY DORECOVER which point of time

Hi,
please clarify to which point of time option DORECOVER will recover standby database 10.2.0.3
- to start of duplicate command time
- as far as archivelog are provided ?
- some other option :)
Regards.
Greg

The name logged in the controlfile when the ArchiveLog was created !
(Thus, even if you keep changing the log_archive_dest for a database -- e.g. to switch between two different filesystems -- Oracle maintains the fully qualified path name).
OT :
However : not related to your DUPLICATE FOR STANDBY ..... but, for example, when doing a RECOVER USING BACKUP CONTROLFILE : if the archivelog filename is not in the controlfile (as the archivelog is "future" to the controlfile backup), Oracle generates the file name from log_archive_dest and log_archive_format, although here, too, you can override the generated name with a SET ARCHIVELOG DESTINATION in RMAN and LOGFILE clause in SQLPlus RECOVER.

Duplicate database for standby from active database

I'm running 11.1.0.7. Has anybody ever duplicated a standby database from active database and the active database being a physical standby open for read only with active dataguard instead of a primary dataguard database?
The key here is location. The primary is located at a remote site where network bandwidth is inadequate for fast copy of database. The active standby database is at same site where I would like to build the new physical standby.

I don't think you can, because "You cannot CONNECT RMAN to the standby database and then use DUPLICATE ... FOR STANDBY to create an additional standby database " and you can't fake it out by getting a controlfile from the primary because the controlfile has to match up with the backup and can't be a standby.
But I'm wondering if you could failover to the standby, duplicate, fail back, then... oh well, that will never work either, incarnation problem.
Snapshot standby? Could one back it up, then flashback restored new standby, change dbid? I would guess there would be an SCN problem, but don't know enough about it.

A new way to track changes of a project? (old way: duplicate sequences)?

Howdy there; continuing my quest to become familiarized with Final Cut Pro X (amazed at the learning curve, coming as a professional from Legacy, really).
A big part of my FCP Legacy workflow was duplicating sequences as I made progress on my sequences so that at any given time, if I felt the direction I'd been taking a few hours prior was preferable, I could go back to one of those old edits/sequences, and re-start from there.
With FCPX's doing away with sequences, how is one to pull-off a similar "never-lose-your-changes" workflow?
I want to be able to experiment like crazy, quickly. And if I find that I took certain things the wrong direction, I could revert back to a slightly older version and take it from there. I'm looking to recreate the same idea in FCPX.
Gracias amigos.
Blake

@bobby:
that's an interesting idea: to create auditions of entire sequences.... but all-in-all that is probably better suited for small clusters of things rather than complex timelines.

Duplicate vs Standby -- What To Do Without Data Guard

WHAT WE HAVE
Three 10.2.0.3.0 databases in production on the same Linux x86 server (Red Hat OS). An identical Linux x86 server (with same OS) is available for housing a corresponding backup instance (either duplicate or physical standby).
THE ASSIGNMENT
Develop a plan that, in the event of a loss of our prod server, provides the shortest time before substitute databases are up and running on the backup server. WE CANNOT USE DATA GUARD (due to server licensing issues). It isn't necessarily a high priority to apply archive logs to duplicates or standbys on a regular basis, but I realize the more up-to-date a backup database is, the less recovery time would be needed if and when it's pressed into service. (BTW: We take weekly incremental level 0 and daily incremental level 1 backups of our prod databases with RMAN and keep them for 28 days.)
QUESTIONS
1. Does our 'no Data Guard' rule eliminate using standbys - even if I could use OS processes to transfer archive logs between servers and manually apply redo? (I'm not quite sure what exactly constitutes Data Guard.)
2. If I'm allowed to create standbys, I'll create them using RMAN. Since the scenario being planned for is a loss of the production server, I figure I'm worried about failover and not switchover. Thus, once standbys are created, in addition to manually transferring and applying archives and creating redo files for them, what other action(s) would I need to take before they could be activated, if that's ever needed? Would the redo files I would have to create be of type STANDBY or ONLINE?
3. Can a standby be opened in read/write mode without being activated?
4. If I can only use duplicates and if the production server were to go down one day, could the most recent valid RMAN backup(s) for the prod databases be used in recovering the duplicates?
I'd prefer the backup instances have the SAME SID (db_name) as the corresponding one in prod, if possible.
Thanks.

Hi
1. Does our 'no Data Guard' rule eliminate using standbys - even if I could use OS processes to transfer archive logs between servers and manually apply redo? (I'm not quite sure what exactly constitutes Data Guard.)
Ans:- yes if you are able to transfer archivelog to standby destination ,you also have to register archivelogs in controlfile manually,then only you can recover standby with archivelogs.
2. If I'm allowed to create standbys, I'll create them using RMAN. Since the scenario being planned for is a loss of the production server, I figure I'm worried about failover and not switchover. Thus, once standbys are created, in addition to manually transferring and applying archives and creating redo files for them, what other action(s) would I need to take before they could be activated, if that's ever needed? Would the redo files I would have to create be of type STANDBY or ONLINE?
Ans:- Yes you can use RMAN to create standby database.you need to activate standby only with the case of failover.Standby logfile is needed if you use Real Time redo apply .In your case you are not enabling Data Guard to transport logs ,so it is not possible to Real Time apply.
3. Can a standby be opened in read/write mode without being activated ?
Ans:- Yes,If you do switchover/failover to open for read/write.Without switchover/failover you can open only in read only mode.
4. If I can only use duplicates and if the production server were to go down one day, could the most recent valid RMAN backup(s) for the prod databases be used in recovering the duplicates?
Ans:- IF you make duplicate database then it will not accept any log from primary database.
Hope this will help you.

ORA-16191: Primary log shipping client not logged on standby.

Hi,
Please help me in the following scenario. I have two nodes ASM1 & ASM2 with RHEL4 U5 OS. On node ASM1 there is database ORCL using ASM diskgroups DATA & RECOVER and archive location is on '+RECOVER/orcl/'. On ASM2 node, I have to configure STDBYORCL (standby) database using ASM. I have taken the copy of database ORCL via RMAN, as per maximum availability architecture.
Then I have ftp'd all to ASM2 and put them on FS /u01/oradata. Have made all necessary changes in primary and standby database pfile and then perform the duplicate database for standby using RMAN in order to put the db files in desired diskgroups. I have mounted the standby database but unfortunately, log transport service is not working and archives are not getting shipped to standby host.
Here are all configuration details.

Sequence Error During Golden Gate Replication!

Dear All,
I am replicating 2 databases one way, from production to standby using golden gate.
Both databases are 11gR2 and on Linux.
Replication runs smooth for couple of days and then ends up with this error:
ERROR OGG-01296 Error mapping from ETISLBILLING.PAR_TBLPARNODEIDENTI to ETISLBILLING.PAR_TBLPARNODEIDENTI.
Parent Ket Not Found ETISLBILLING.FK_PARTNERNODE_IDENT
Trigger : ETISLBILLING.TRG_PAR_TBLPARTNERNODE Sequence : SEQ_PAR_TblPartnerIdenti
ORA-20000: Sequence value cannot be changed.
Main error is that value of sequence that is executed during the after insert trigger, does not change and trigger raise error hence the replication process is stopped.
I am just worried that the same triggers and sequences are executed successfully on production database and standby database has is exactly the same as production.
Is there some special treatment for sequences?
Kindly help on this.
Regards, Imran

Best practice on using Flashback and Logical Standby

Hello,
I'm testing a fail-back scenario where I first need to activate a logical standby, then do some dummy transactions before I flashback this db and resme the redo apply. Here is what the steps look like:
1)     Ensure logical standby is in-sync with primary
2)     Enable flashback on standby
3)     Create a flashback guaranteed restore point
4)     Defer log shipping from primary
5)     Activate the logical standby so it’s fully open to read-write
6)     Dummy activities against the standby (which is now fully open)
7)     Flashback the database to the guaranteed checkpoint
8)     Resume log shipping on primary
9)     Resume redo apply on secondary
In the end, i can see the log shipping is happening but the logical standby does not apply any of these..and there is no error in the alert log on Standby side. But the following query could explains why the standby is idle:
SELECT TYPE, HIGH_SCN, STATUS FROM V$LOGSTDBY;
TYPE HIGH_SCN STATUS
COORDINATOR ORA-16240: Waiting for log file (thread# 2, sequence# 0)
ORA-16240: Waiting for log file (thread# string, sequence# string)
Cause: Process is idle waiting for additional log file to be available.
Action: No action necessary. This informational statement is provided to record the event for diagnostic purposes.
I dont understand why it's looking for sequence #0 after the flashback.
Thanks for the help.

Do you really have a thread 2? ( Redo thread number )
Quick check

Error while trying to open physical standby database - (DATA GUARD)

Hi Everyone,
I have problems in opening the database of the physical standby in read- write mode/ read only mode. I have a primary server which is running on 2 node RAC and the standby on a seperate single server being used as DR. I recently got this server and my aim was to isolate the standby server from primary server and perform few test. As it has never been tested even once.
Primary Database spec: (2 Node Rac on ASM)
Oracle Version : 10.2.0.3.0
O/s : HP-UX B.11.23
Standby Database spec: (Single Node)

alter database mount standby database;
alter database recover managed standby database disconnect;
alter database recover managed standby database cancel;
alter database open/readonly (tried both)

There is a delay of 20 minutes before the logs get applied. which has been intentional set by team.

I tried log switch multiple times in primary database i saw that its getting highlighted in standby database.

Is that possible to convert logical standby to physical standby ?

Hi guys,
My 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 enabled
Managed Standby Recovery starting Real Time Apply
MRP0: Background Media Recovery waiting for new incarnation during transient logical upgrade procedure
Errors in file /home/ora/app/oracle/diag/rdbms/ora11gr1dg/ora11gr1dg/trace/ora11gr1dg_mrp0_10120.trc:

Hello;
Because of limitations for specific data types and objects with a logical database I going to say no.

Onlilne HDCAM edit - what sequence/capture settings?

Good Afternoon,
We have completed the offline edit of a 3 minute video that was shot on HDCAM,then edited using low-res Photo JPEG.
Using Media Manager we are planning to create a duplicate sequence to use to capture and connect the clips to the HDCAM footage.
What sequence settings do we use and what capture preset do we use? The manual isn't very clear on this.
Thanks!

That's the card...not the drives. What DRIVES do you have? What DRIVE ARRAY? The card will be fast enough...if the raid array attached to it is fast enough.
How fast is it? I don't know...you need to test that out. Use the AJA Kona System Test application found here:
