Redo log file is full or not

Hi everybody,
In Oracle I wanna know the current capacity of a log group, so I will know/estimate when it will be switched. For example, I have three log groups 1, 2 and 3, each log group has only 1 member of size 10MB. So I want to check how full the current log group is? 1MB, 3MB or 7MB... When it's 9MB I know it's going to switch.
But currently I can't find the solution. I see the LAST_REDO_BLOCK in v$thread. v$thread presents status of current log group. When I do 'alter system switch logfile', LAST_REDO_BLOCK resets to 0 and increase slowly. I try to create table and insert multi rows, and LAST_REDO_BLOCK increase fast. So anybody can tell me if LAST_REDO_BLOCK is the current number of blocks in the current log group, and I can calculate the current size of a log group? If not, any possible solutions?
Sorry for my bad English and thank you for reading.

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.

Physical Standby Online Redo log files,

Hi,
I'm trying to create a physical standby database (10.2.0.3). I'm a little confused about the requirement for online redo logs on the standby.
in my standby alert log I get the following when I issue:
SQL> alter database recover managed standby database disconnect from session
"ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/appl/oradata/prod/prod_1_redo_01_02.log'
ORA-27037: unable to obtain file status
SVR4 Error: 2: No such file or directory
Additional information: 3"
/appl/oradata/prod/prod_1_redo_01_02.log is the path to the location of the online redo logs on the production system. This file does not exist on the standby filesystem so the error is correct.
I assume that it gets this information from the standby control file I created on the production system and copied over to the standby.
Do I need to copy the online redo logs from the primary over to the standby site or do I need to create online redo logs on the standby?
Does the standby need to have redo log files?
I'm not talking about 'standby log files' of the type created using 'alter database add standby log file'. I've not got that far yet.
I just need to establish if a physical standby requires online redo log files?
Thanks in advance,
user234564

I wanted to update this thread since I've been dealing with the exact same errors. The basic question is: "does a physical standby need the online redo logs?"
Answer: Not really, until one wants to switchover or failover (and become a primary database). Furthermore, whenever the MRP process is started, Oracle prepares for a possible switchover/failover by "clearing" the online redo logs (MetaLink note# 352879.1). It is not a big deal, since Oracle will build the actual redo files when the "alter database open resetlogs" is accomplished during a "role transition."
In our situation, we have decided to use our standby for nightly exports. We stop MRP, open the database read-only, then restart MRP. We built these standby DBs with RMAN. The RMAN duplicate process will not build the online redo log files until the database is opened for read/write (with resetlogs). However, we haven't had a need for read/write (i.e. a switchover).
Thus, every morning we have been getting the same errors that "user234564" posted above. At first the errors seemed scary, then we realized they were just a nusiance. In order to clean things up, all I did was just "cp" our stanby redo logs (SRL) into our online redo directories ensuring the names matched what was in v$logfile. When I restarted MRP, the alert log clearly showed Oracle clearing these "newly found" online redo logs.

Redo log files are not applied in DR of primary

Hi All,
I have a DR database of primary on QA Serevr. The Redo log files are not properly applied in the DR database.
The Oracle version is 11.2.0.1 Some of the files get shipped and applied to DR database automatically but not all.

Database in log archive mode and redo log file in mode not archive

Hello,
I have a dabatabase running in archive log mode, recently changed, I have 5 redo log groups and one of them (the current one) shows in the v$log view, that ARC: NO, I mean, no archiving. All redo logs except it shows ARC:Yes
What does it mean?
Am I going to have problems with this redo log file?
Thanks

If you do describe on v$log, you'll find that the full column name is Archived (meaning is it archived yet?).
You could try alter system switch logfile and then check v$log again a few times after.
Use the docu for finding out more about v$ views and so on

How often should a database archive its logs
Re: Redo log size increase and performance
Please read the above thread and great replies by HJR sir. I think if you wish to get concept knowledge, you should add in your notes.
"If the FAST_START_MTTR_TARGET parameter is set to limit the instance recovery time, Oracle automatically tries to checkpoint as frequently as necessary. Under this condition, the size of the log files should be large enough to avoid additional checkpointing due to under sized log files. The optimal size can be obtained by querying the OPTIMAL_LOGFILE_SIZE column from the V$INSTANCE_RECOVERY view. You can also obtain sizing advice on the Redo Log Groups page of Oracle Enterprise Manager Database Control."

Redo log file corupted, database not getting open

I am Oracle Funda-1 student.
Have install standard Oracle 9I on Windows XP pro service pack 2.
I made some changes in sample table & given commit. So log buffer will flush to redo log file.
Then I open current redo log file from OS & selected all junk characters [select all] & deleted same. Save the file. Causing redo file size 0KB.
Then made more changes to table & issue commit. no errors ! every thing working file.
Even chked V$log & V$logfile.
Again I open current redo log file from OS & selected all junk characters [ select all ] & deleted same. Save the file. Causing redo file size 0KB.
Then issue manual log switch. Alter system switch logfile
I got disconnected from database & database was close.
When I reconnected & try to open database in normal mode. Gave error saying redolog_1.log is corrupted & needed for recovery.
Now not even allowing me clear redo group 1. with alter database clear logfile group 1. as database is not coming to open stage.
just able to mount the database. with error rdolog_1 corrupted.
Wasn't oracle suppose to be halted when very 1st time I corrupted redo log file.
Why it disconnected me & got close.
When then one use alter database clear logfile group 1.

I may try this ALTER DATABASE OPEN RESETLOGS;
As no backup & not multiplex.
Still looking for explanation why database got close down instead of getting halt.
I have found one more status in V$log, which is not given in Oracle university book or online document.
INVALIDATED
Which come as a result when oracle unable to switch to next on line group due to non availability of next group redo log physical file.
SQL> select group#,members,status from V$log;
GROUP# MEMBERS STATUS
1 1 INVALIDATED
2 1 INACTIVE
4 1 UNUSED
As matter of fact, it's only portion of a big
document which happen to cover what you are testing
in detail.
I would invest time to read the document to
understand how things work instead of getting dirty

Restore in noarchivelog mode ( redo log files have been dropped )

1, A full backup taken using RMAN is available on disk.
2, The current control files were NOT damaged and do not need to be restored.
3, All data files are damaged .
4, The database is in NOARCHIVELOG mode.
I restore database :
1. RMAN> STARTUP MOUNT
2. RMAN> RESTORE DATABASE;
3. RMAN> recover database;
in this step , I got the information about needing redo log files ; but the redo log
files have been dropped , what should i do ?
else
I want to know there is the command 'recover database using backup control file'
in rman or not ?
Tks

Possibly loss of data (because information in online redo logs is lost):
recover database until cancel;
(cancel immediately)
alter database open resetlogs; (to build a new set of redo logs)
It's not necessary to use a backup controlfile here.

Hoping for a quick response : EXP and Archived REDO log files

I apologize in advance if this question has been asked and answered 100 times. I admit I didn't search, I don't have time. I'm leaving on vacation tomorrow, and I need to know if I'm correct about something to do with backup / restore.
we have 10g R2 running a single instance on a single server. The application vendor has "embedded" oracle with their application. The vendor's backup is a batch file using EXP - thus:
exp system/xpwdxx@db full=y file=D:\Orant\admin\db\EXP\db_full.dmp log=D:\Orant\admin\db\EXP\db_full.txt direct=y compress=y
This command is executed nightly at midnight. The files are then backed up by our nightly backup to offsite storage media.
Te database is running in autoarchive mode. The problem is, the archived redo files filled the drive they were being stored on, and it is the drive the database is on. I used OS commands to move 136G of archived redo logs onto other storage media to free the drive.
My question: Since the EXP runs at midnight, when there is likely NO activity, do I need to run in AutoArchive Mode? From what I have read, you cannot even apply archived redo log files to this type of backup strategy (IMP) Is that true? We are ok losing changes since our last EXP. I have read a lot of stuff about restoring consistent vs. inconsistent, and just need to know: If my disk fails, and I have to start with a clean install of Oracle and nothing else, can I IMP this EXP and get back up and running as of the last EXP? Or do I need the autoarchived redo log files back to July 2009 (136G of them).
Hoping for a quick response
Best Regards, and thanks in advance

Amardeep Sidhu
Thank you for your quick reply. I am reading in the other responses that since I am using EXP without consistent=y, I might not even have a backup. The application vendor said that with this dmp file they can restore us to the most recent backup. I don't really care for this strategy as it is untested. I asked them to verify that they could restore us and they said they tested the dmp file and it was OK.
Thank you for taking the time to reply.
Best Regards
BruceThe dump file is probably ok in the sense it is not corrupted and can be used in an imp operation. That doesn't mean the data in it is transactionally consistent. And to use it at all, you have to have a database up and running. If the database is physically corrupted, you'll have to rebuild a new database from scratch before you can even think about using your dmp file.
Vendors never understand databases. I once had a vendor tell me that Oracle's performance would be intolerable if there were more than 5 concurrent connections. Well, maybe in HIS product ..... Discussions terminated quickly after he made that statement.

Redo log and Disk Full

hi
all
i'm new oracle DBA. i had one problem is
my Database is in archive mode. now redo log is available but not archive and my disk is full. so i couldn't open my Database what i have to do next step please help me...
Thanks in advance

Take a proper copy of all the archived log files from the archive destination to some backup media like tape(for future recoverability) and delete them off from the disk to avail for space on the disk.
You will then be able to open your DB and proper archiving will take place.
What is happening?
The ARCHiver process is finding no space on the disk to archive the redo log files and thus Oracle stops doing any further action since it is in archive log mode.

Missing current redo log files

hello to all
i have a question please if you can guide me.
if i lose all current redo log files (current redo log group files) how i can repair it and open
database ? (i don't have problem by missing INACTIVE redo group)
thanks

Hi,
>>if i lose all current redo log files (current redo log group files) how i can repair it and
open database ? (i don't have problem by missing INACTIVE redo group)Well, It depends. The database was active when the current log file was lost ? Are you using RMAN ? The database is operating in ARCHIVELOG mode or NOARCHIVEMOG mode ? Basically, an incomplete recovery is necessary when there is a loss of the current redo log files. It means that you don’t have all the redo log files up to the point of failure, so the only alternative is[b] to recover prior to the point of failure. To perform incomplete recovery after the redo log files have been lost, you do the following (if you are not using RMAN):
1) Execute a SHUTDOWN command and restore all data files (*.dbf) from most recent backup.
2) Execute a STARTUP MOUNT command to read the contents of the control file.
3) Execute a RECOVER DATABASE UNTIL CANCEL command to start the recovery process.
SQL> startup mount;
4) Execute a RECOVER DATABASE UNTIL CANCEL command to start the recovery process.
SQL> recover database until cancel;
5) Apply the necessary archived logs up to, but not including, the lost or corrupted log.
6) Open the database and reset the log files.
SQL> alter database open resetlogs;
7) Shut down the database.
SQL> shutdown normal;
8) Take a full cold backup

Thanks very much for your help guys. I appreciate it. unfortunately none of these commands worked for me. I kept getting error on clearing logs that redo log is needed to perform recovery so it can't be cleared. So I ended up restoring from earlier snapshot of my db volume. Database is now open.
Thanks again for your input.And now, as a follow-up, at a minimum you should make sure that all redo log groups have at least 3 members. Then, if you lose a single redo log file, all you have to do is shutdown the db and copy one of the good members (of the same group as the lost member) over the lost member.
And as an additional follow-up, if you value your data you will run in archivelog mode and take regular backups of the database and archivelogs. If you fail to do this you are saying that your data is not worth saving.

DROP and recreate the database. It is a *new* database without any data.
Check what datafile locations and redo log file locations you specify when creating the new database. Check if you have permissions and enough disk space.

Hi, Yingkuan,
Thanks for the helps.
Actually, I have 10 redo log files exists. All of them are here.
I tried your suggestion:
alter database clear unarchived logfile group 4;
The error msg I got is the same as before:
SQL> alter database clear unarchived logfile group 4;

Compared to losing all the data, it is OK for me lose some of them.
I have more than 1 TB data stored and 99.9% of them are raster images.
The loading of these data were the headache. If I can save them, I can bear the lost.
I want to grasp the last straw.
But I don't know how set the parameter: allowresetlogs_corruption
I got the error msg:
SQL> set allowresetlogs_corruption=true;
SP2-0735: unknown SET option beginning "_allow_res..."
I have run the command:
Recover database until cancel
Alter database open resetlogs
The error msg I got is the following:
SQL> recover database until cancel
ORA-00279: change 41902930 generated at 11/05/2007 22:01:48 needed for thread 1

From the log file, I got the following:
