Second copy of redo log with scp.

Hello,
As I had asked in brarchive configuration for a scp second copy,
I would like to use brarchive to do a first copy on our tape robot with backint and and second copy with scp.
When I test:
brarchive -s -c -u / -p initTST.brarchive.sap -> works fine
brarchive -sc -c -u / -p initTST.scp.sap -> does not work
BR0002I BRARCHIVE 7.10 (27)
BR0181E Option '-sc' not supported for 'stage'
initTST.scp.sap contains the following:
backup_dev_type    = stage
stage_copy_cmd     = scp
archive_stage_dir = /xxx/yyy
remote_host        = host.unige.ch
remote_user        = username
Is there something that I would have missed in the config or there is no way to get a second copy with scp?
Thanks in advance for your answer.

Hello,
I have tested brarchive -s with stage option.
As you said it works.
#STAGE.... 51 /oracle/TST/saparch/TSTarch1_51_729768278.dbf 2010-09-24 11.37.54 29248000         364646402 1
#STAGESAV. aeeeripp sve xxx/TSTarch1_51_729768278.dbf 2010-09-24 11.38.51 ........... ............
#STAGEDEL. ........ ... .......... ........
If run a second brarchive -scd, with util_file, it does not find any "saved" redo.
There are only "archived" redo.
Therefore it does not save it.
If I run brarchive -sd with util_file, it finds the redo, saves it and deletes it.
#ARCHIVE.. 51 /oracle/TST/saparch/TSTarch1_51_729768278.dbf 2010-09-24 11.37.54 29248000         364646402 1
#SAVED.... aeeerjgt svd *1285321566       2010-09-24 11.46.58 ........... ............
#COPIED... ........ ... ................. .......... ........ ........... ............
#DELETED.. aeeerjgt svd 2010-09-24 11.46.58
TST util_file aeeerjgt svd 2010-09-24 11.46.03 2010-09-24 11.46.58 9 ...........        51       51        0        0 ------- 7.10 (27) @0729768278
Therefore the brarchive with util_file consider that the redo has never been saved (by the brarchive with stage options).
Now I have a pseudo solution.
By pseudo, I mean that the redo is deleted after a successfull copy to my tape robot even if the stage did not completed
successfully.
Do I have a way to tell brarchive that it should delete only if it has been STAGESAV AND SAVED?
Thanks in advance for your answer.

Adding online redo logs with standby database in place

Hi group,
I have decided to add one new member to my existing redo log groups and an additional redo log group to my primary database.
That change went ok without problems. I assumed that with standby_file_management=auto the equivalent online redo logs are created on the standby database. But this is not the case.
The documentation is unclear about this point and I did not find anything suitable on metalink. The docs suggest to cancel managed recovery on the standy, setting standby_file_management to MANUAL and then adding online logs, quote:
"To add an online redo log, use a SQL statement such as this:
SQL> ALTER DATABASE ADD STANDBY LOGFILE 'prmy3.log' SIZE 100K;"
This however - IMO - adds a new STANDBY redo log to the standby database, what I need is an ONLINE redo log.
Does anybody have some experience to share here?
Facts:
Solaris 8
Oracle 9.2.0.6
Thanks!
Martin

OK, for those who come across the same problem.
You need to create a new standby controlfile, copy it as well as any new online redo log from production to the standby environment.
Once the files are in place, start the standby as normal and open it read only to see if everything is ok:
startup nomount
alter database mount standby database;
alter database open read only
Only when there are no errors in your alert.log you are safe.

GoldenGate Extract Process will not read from redo log with manual help

Here is my issue.
I have GoldenGate replication successfully setup one-way from 1 Source to Many Targets. There is 1 source extract on the DB and many pumps that push the trail file data to the Targets. Replication does work but after manual help with starting up the Source Extract process.
If I execute the command:
GGSCI> alter extract <source extract name> begin now
GGSCI> view report <source extract name>
The extract starts and reads the source trail file but will not process data, I continually see in the ggserr.log file "OGG-01515: Positioning to begin time MMM DD, YYYY, HH:MM:SS" The date and time are irrevelant for this problem.
When I see this, I SQ*Plus into the database and look in the v$log table for the current log and sequence #.
I return to GGSCI and issue the following command:
GGSCI> alter extract <source extract name> thread 1 extseqno <sequence # from v$log query>
GGSCI> start <source extract name>
It then works as expected. Why is this so? I thought the alter extract <source extract name> begin now would do the same output.
We do use ASM but like I said when I issue the:
GGSCI> alter extract <source extract name> thread 1 extseqno <sequence # from v$log query>
It works like it should.
Very weird.
- Jason

Yes, supplemental logging is enabled on both the source and the targets, but why would supplemental logging on the targets have any affect on why the Source Extract on the source can't read from the source redo log?
This is not a RAC database, rather single-instance with one thread. Also, we are using DBLOGREADER functionality as it is an 11.2.0.3 database.
My issue is simply, when I start the source extract from being down, meaning it isn't running, I issue this command:
alter <source extract> begin now
start <source extract>
view report <source extract>
OGG-01515 Positioning to begin time <today's date and time> ie Mar 4, 2013, 3:26:39 PM. (this is repeated over and over and over)
If I perform a
info <source extract> detail---> I see the following:
Log Read Checkpoint Oracle Redo Logs 2013-03-04 15:26:39 Thread 1, Seqno 0, RBA 0 (why is it showing 0, becuase it can't read the redo, WHY NOT?)
Extract Source BEGIN END
Not Available <today's date> <today's date> (repeat....)
However, if I retreive the Redo Log number and I issue:
alter spe thread 1 extseqno (redo log sequence #)
start spe.
Then it works okay. I have to manually tell it what redo log to begin reading from. Why?

Logmnr/capure error b'coz of corruption of redo log block

Hi,
We all know that capture process reads the REDO entries from redo log files or archived log files. Therefore we need to ahev db in ARCHIVELOG mode.
In alert log file, I found error saying :
Creating archive destination LOG_ARCHIVE_DEST_1: 'E:\ORACLE\ORADATA\REPF\ARCHIVE\LOCATION01\1_36.ARC'
ARC0: Log corruption near block 66922 change 0 time ?
ARC0: All Archive destinations made inactive due to error 354
Fri Apr 04 12:57:44 2003
Errors in file e:\oracle\admin\repf\bdump\trishul_arc0_1724.trc:
ORA-00354: corrupt redo log block header
ORA-00353: log corruption near block 66922 change 0 time 04/04/2003 11:05:40

ORA-00312: online log 2 thread 1: 'E:\ORACLE\ORADATA\REPF\REDO02.LOG'
As a normal practice, we do have multiplexing of redo log files at diff location, but even that second copy of redo log is of no use to recover the redo log. This explains redo log could not be archived, since it can't be read. Same is true even for Logmnr process, it could not read the redo log file and it failed. Now, we have wae to recover from this situation (as far as DB is concern, not Stream Replication), since the shutdown after this error was IMMEDIATE causing checkpoing, and rollback/rollforward is not required during system startup. (No instance recovery) We can make db NOARCHIVELOG mode, drop that particular group, and create new one, and turn db to ARCHIVELOG mode This will certainly serve the purpose as far as consistency of DB is concern.
Here is a catch for Stream Replication. The redo log that got corrupted must be having few transaction which are not being archived, and each will be having corresponding SCN. Now, Capture Process read the info sequentially in order of SCN. Few transaction are now missed, and Capture process can't jump to next SCN skipping few SCN in between. So, we have to re-instantiate the objects on the another system which has no erros, and start working on it. My botheration is what will happen to those missed transaction on the another database. It's absolete loss of the data. In development I can manage that. But in real time Production stage, this is a critical situation. How to recover from this situation to get back the corrupted info from redo log ?
I have not dropped any of the log group yet. B'coz I would like to recover from this situation without LOSS of data.
Thanx, & regards,
Kamlesh Chaudhary

10G redo log switchs with no activity

We have been testing 8i to 10G migrations and two things I have noticed that are different bwteeen the 2 databases are:
1) redo log switching occurring even though the database has no users and just sitting there. This is not happeniong in our 8i databases.
2) trace files of format instance_m001_ and instance_m000_ in ../bdump. Our 8i bdump's normally do not have trc files unless a problem occurs.
Is it normal for 10G to automatically switch redo logs with no activity and are these .trc files also normal? In general I get nervous with trc files. -quinn

Still haven't figured out the redo log switches, they seem to be slowing down, but the excess trace files are apparently cuased by a bug and can be fixed with Patch 3432729.

Backup of redo log files

Hello,
How can I make a backup with redo log files using the following parameters?
backup_type = online_cons
backup_dev_type = disk_copy
-->archive_function = save_delete (It could be changed. Maybe it is the source of the error)
The copy is made, but an error occurs when it tries to copy the redo log files. The log shows the following message:
BR0291I BRARCHIVE will be started with options '-U -d disk_copy -c force -p initFDP_local.sap -cds'
BR0002I BRARCHIVE 6.40 (43)

Hi Ricard,
You are right, you need to change the entry
archive_function = save_delete
to
archive_function = save
in init<SID>.sap

What is online redo log files???

Dear All,
I m bit confused with redo log files.what is need of back up of redo log files?????As i m new in the Basis please tell me i always get confused with redo log files and archive files.
Thanx and reagard's
Ashok

In Oracle you have a number of online redo log files.
In an typical SAP installation you have two directories:
origlogA and origlogB
origlogA contains online redo log 1 and 3 and
origlogB contains online redo log 2 and 4.
In most installation you also have mirrlogA and mirrlogB, which the name tells, is mirrors of origlogA and origlogB.
Now, the online redo logs are circular,
so when 1 gets full oracle jumps to number 2.
At the same time oracle's archiver process starts to copy
online redo log number 1 to a file on disk.
This files are also known as archive redo logs.
In an recovery situation you might do with just the online redo logs,
but usually a combination of both online and archive redo logs is needed.
During database backup, you also backup the online redo logs
You also need to backup (backup twice then delete) archive redo logs.
the archive redo logs are your way back from the restored database to the last transaction of the database.
If one archive redo log is missing, you have to stop you recovery there and loose the rest of the transactions done in the database.

Unusable redo log

When trying to startup the database
ORA-00314 error message occures
that is the online log is corrupted or is an old version.
Do I have to recover the database from backup
in such a case? I have no other copy of redo log files,
they are just mirrored on disk array.

Hi,
>>there another way than having to recover database from backups.
Maybe ...
Firstly, make a backup of your database files before to try any recover operation.
1) Your database was consistent before this error ? Have you tried re-create your controlfiles with RESETLOGS option ?
2) Maybe using _allow_resetlogs_corruption forces the opening of the datafiles even if their SCNs do not match up; then, on the next checkpoint, the old SCN values are overwritten. This could leave the database in an unknown state as far as concurrency.
Take a look on these links below:

How to clean redo log file?

Hi, guys:
I need to migrate data from external tables to normal tables. But the connection is always frozen half the way of executing script. The error message is ORA-00257. it looks redo log file is full. I tried to delete redo log file with RMAN, but I got this error message:
delete archivelog until time 'trunc(sysdate)';
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=43 device type=DISK
specification does not match any archived log in the repository
Any suggestion would be appreciated.

Sounds like you are confusing (online) redo logs with "archivelogs" (archived redo logs).
You don't delete redo logs at all. You can delete archivelogs with rman, which is what your command is trying to do. Do you ever backup the archivelogs? A proper backup/recovery policy would backup the archivelogs on at least a daily (if not more often) basis, and delete them after they are backed up. That will keep the archivelog destination from filling up in all but the most extreme circumstances.

No. It is a once off copy of the imported files. The second copy is not associated with the catalog at all.

Unable to copy redo-logs for cloning

Hello
We are using R12 with 10.2.0.2 db
we take db tier backups every night and apps backup twice a month(15 days interval)
We normally run autocfg.sh and adprecolne.pl on dbTier.After this we stop all services, shutdown the database and copy all the datafiles,controlfiles and logfiles)
This backup is helpful in restoration in case any failure on PROD server and for cloning purpose on an another node for testing purpose
Now my question is, are we doing the clone procedure properly or is there a better way for cloning for suppose RMAN..or maybe any other
Secondly, Last night all the datafiles got copied after a clean shutdown except for logfiles.
Will i be able to restore the data later if i dont have the log files? can i build new logfiles?
Will this data be succesful for cloning without the redo logs
Please Note: This is a cold backup we take i.e Consistent backup
Thanks

I would go against the oft-repeated and common "Expert" and "Documentation" advice here.
If you are doing a COLD Backup and are are planning to use the Backup to restore to another server, there is no harm in taking the online redo logs as well.
Where the risk with online redo log backups arises is when the SysAdmin/DBA , when doing a FullRestore also restores the online redo logs back to the target database overwriting any present online redo logs.
For this to occcur :
a. The SysAdmin/DBA happens to restore all the files in the backup set without selectively excluding the online redo logs
b. The databases's online redo logs are present and good on disk
c. The DBA isn't very confident of being able to rollforward through his redo logs
It is for those reasons that it is easier to advice everyone not to backup online redo logs.
However, as I've noted above, if you are doing a Cold Backup and restoring to another server (with no database present at the target site), there is no harm in taking the online redo logs. Such a backup and restore makes your scripting very easy and doesn't even need a DBA.

Hi,
since you are getting a read error, it might as well be, that your datafile is defective.
Try the same dd-command to /dev/null, to see if it is possible to read the entire file.
First make sure that your null-device is existing, otherwise you might face a root-fs full problem.
dd obs=1024K bs=1024K if=/oracle/ANP/sapdata2/sr3_9/sr3.data9 of=/dev/null
or try a dbverify on it, which would also read the entire file and do a checksum test.
brbackup -c -u / -m /oracle/ANP/sapdata2/sr3_9/sr3.data9 -t online -w only_dbv
Good luck
Volker
