Recovery in archive mode, but no archived logs

Hi,
I hope someone can help me with the following question.
I have a 9.2 database in archive mode. Suppose on t=t0 I make an online backup. At the end of this run, I will do an "alter system switch logfile" statement to capture the latest transactions (more or less also at t=t0). Later, at t=t1 we do some transaction and more archived redologs are created. At t-t2 I need to restore the complete database, but I have LOST all the archive files as from t=t0. Now the question is, is it still possible to recover (even it means to go back to t=t0)? I have tried it, but always the system suggests to apply the (missing) archived redo's, and it seems I cannot escape this. But, Is it possible to get back to t=t0?
Thanks a lot, for any clue or pointer !

If you take a hot backup and you lose the redo logs, you have a fundamentally inconsistent backup. Each tablespace will be internally consistent, but they probably won't have the same SCN as the control files, so you'll get this message.
Do you have an earlier hot backup and the archived logs that would restore that backup to the point in time (t=0) where you took the latest hot backup? Personally, I generally like to keep at least 2 or 3 old backups, with archived log files, just in case something goes wrong with the most recent backup.

Chane archive mode to non archive mode

hi
how can i change a an archived database to n on_archive database

Issue the following commands to put a database into ARCHVELOG mode:
1) Take Back up of Present SPfile by creating pfile " pfile path " from present spfile.
2) Shutdown the database by SUTDOWN IMMEDIATE.
3) Take Cold backup of the database in repsective place .
4) Change the parameter in the pfile.
log_archive_start = FALSE
log_archive_dest_1 = 'LOCATION=F:\Backup\Archive'
log_archive_dest_state_1 = DISABLE
log_archive_format = %d_%t_%s.arc
5) And make a spfile from the modified pfile in default location .
6) Start the database with spfile.
SQL> CONNECT sys AS SYSDBA
SQL> STARTUP MOUNT ;
SQL> ALTER DATABASE NOARCHIVELOG;
SQL> ARCHIVE LOG STOP;
SQL> ALTER DATABASE OPEN;
NOTE 1: Remember to take a baseline database backup right after enabling archivelog mode. Without it one would not be able to recover.
Also, implement an archivelog backup to prevent the archive log directory from filling-up.

Converting DB in archive mode

hi buddies;
I got, three DBs with ASM in Oracle RAC (2 nodes). Two of these DBs are in archive mode, but one of them, no. So, I'm going to convert this one (DATABASE3) in archivemode now. I got the instructions to do this, but still I have some doubts, So I need your 'inputs' to be sure that I'm right.
These are the steps I understand I should follow.
1. Login to one of the nodes (i.e. linux1) and disable the cluster instance parameter by setting
cluster_database to FALSE from the current instance:
2. $sqlplus "/ as sysdba"
SQL> alter system set cluster_database=false scope=spfile sid='DATABASE3_1';
3. Shutdown all instances accessing the clustered database:
$ srvctl stop database -d DATABASE3
Using the local instance, MOUNT the database:
$ sqlplus "/ as sysdba"
SQL> startup mount
Enable archiving:
SQL> alter database archivelog;
Re-enable support for clustering by modifying the instance parameter cluster_database to TRUE from the current instance:
•     SQL> alter system set cluster_database=true scope=spfile sid='DATABASE3_1';
•     Shutdown the local instance:
•     SQL> shutdown immediate
•     Bring all instance back up using srvctl:
•     $ srvctl start database -d DATABASE3
My databases are:
+ASM
DATABASE1
DATABASE2
DATABASE3 --- This is the DB in noarchivemode.
My doubts are:
In step 3, says 'shutdown all instances', means all instances in both nodes, except the instance I'm going to change and ASM in that node?
Any recomendation, or suggestions, you understand I should be alert?
Regards;
ANG

Hi,
You do not need to shutdown any other database than the database which you want to change to archive log. The target database needs to be shutdown on all nodes to folow your instruction. All other database running in archivelog will stay up.

Hello Subbu,

You mean you have taken an online backup and lost all your archive log files after that online backup?
SQL> alter database open resetlogs;
Error: ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: 'E:\oracle\'<SID>\sapdata1\SYSTEM_1\SYSTEM.DATA1'

ORA-00280: change 266277189 for thread 1 is in sequence #3020
To perform a recovery with an online backup you will need all archive log files until the end of the online backup. If you have lost them you are not able to recover (or open) your database in a consistent state.
So the only suggestion we can do is:
You need the archive log files that were created during the online backup to perform an incomplete recovery ... if they are gone you can not restore your database.

If you have a cold backup (database shutdown properly) without the redo logs, change this :
CREATE CONTROLFILE REUSE DATABASE "XE" NORESETLOGS NOARCHIVELOGto
CREATE CONTROLFILE REUSE DATABASE "XE" RESETLOGS NOARCHIVELOGYou have to change the NORESETLOGS to RESETLOGS for Oracle to recreate the online redo logs.

Incomplete Recovery Fails using Full hot backup & Archive logs !!

Hello DBA's !!
I am doing on Recovery scenario where I have taken One full hot backup of my Portal Database (EPR) and Restored it on New Test Server. Also I restored Archive logs from last full hot backup for next 6 days. Also I restored the latest Control file (binary) to their original locations. Now, I started the recovery scenario as follows....
1) Installed Oracle 10.2.0.2 compatible with restored version of oracle.
2) Configured tnsnames.ora, listener.ora, sqlnet.ora with hostname of Test server.
3) Restored all Hot backup files from Tape to Test Server.
4) Restored all archive logs from tape to Test server.
5) Restored Latest Binary Control file from Tape to Test Server.
6) Now, Started recovery using following command from SQL prompt.
SQL> recover database until cancel using backup controlfile;
7) Open database after Recovery Completion using RESETLOGS option.
Now in Above scenario I completed steps upto 5) successfully. But when I execute the step 6) the recovery completes with Warning : Recovery completed but OPEN RESETLOGS may throw error " system file needs more recovery to be consistent " . Please find the following snapshot ....

Note : I tried to Open the database using Last Full Hot Backup only & not applying any archives. Then Database Opens successfully. It means my Database Installation & Configuration is OK !
Please Let me know why my Incomplete Recovery using Archive logs Goes Fail ?
Atul Patil.

oh you made up a new thread so here again:
there is nothing wrong.
You restored your backup, archives etc.
you started your recovery and oracle applyed all archives but the archive
'/oracle/EPR/oraarch/1_9624_601570270.dbf'
does not exist because it represents your current online redo log file and that is not present.
the recovery process cancels by itself.
the solution is:
restart your recovery process with:
recover database until cancel using backup controlfile
and when oracle suggests you '/oracle/EPR/oraarch/1_9624_601570270.dbf'
type cancel!
now you should be able to open your database with open resetlogs.

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

CONFIGURE DATABASE IN ARCHIVE MODE

Hai
I am just trying to change the database to archive mode.As part of this I need to set the parameter LOG_ARCHIVE_START to TRUE in the init.ora file.But I am not able to find this parameter in the init.ora file(any of the archive parameter for that matter).Please advise where can I find and set LOG_ARCHIVE_START parameter.
Thanks
Jay

LOG_ARCHIVE_DEST
Parameter type
String
Syntax
LOG_ARCHIVE_DEST = filespec
Default value
Null
Parameter class
Dynamic: ALTER SYSTEM
Range of values
Any valid path or device name, except raw partitions
Real Application Clusters
Multiple instances can have different values.
Note:
For Enterprise Edition users, this parameter has been deprecated in favor of the LOG_ARCHIVE_DEST_n parameters. If Oracle Enterprise Edition is not installed or it is installed, but you have not specified any LOG_ARCHIVE_DEST_n parameters, this parameter is valid.
LOG_ARCHIVE_DEST is applicable only if you are running the database in ARCHIVELOG mode or are recovering a database from archived redo logs. LOG_ARCHIVE_DEST is incompatible with the LOG_ARCHIVE_DEST_n parameters, and must be defined as the null string ("") or (' ') when any LOG_ARCHIVE_DEST_n parameter has a value other than a null string. Use a text string to specify the default location and root of the disk file or tape device when archiving redo log files. (Archiving to tape is not supported on all operating systems.) The value cannot be a raw partition.
If LOG_ARCHIVE_DEST is not explicitly defined and all the LOG_ARCHIVE_DEST_n parameters have null string values, LOG_ARCHIVE_DEST is set to an operating system-specific default value on instance startup.
To override the destination that this parameter specifies, either specify a different destination for manual archiving or use the SQL*Plus statement ARCHIVE LOG START filespec for automatic archiving, where filespec is the new archive destination. To permanently change the destination, use the statement ALTER SYSTEM SET LOG_ARCHIVE_DEST = filespec, where filespec is the new archive destination.
Neither LOG_ARCHIVE_DEST nor LOG_ARCHIVE_FORMAT have to be complete file or directory specifiers themselves; they only need to form a valid file path after the variables are substituted into LOG_ARCHIVE_FORMAT and the two parameters are concatenated together.

RMAN in non-archive mode

All,
My database is running in NOArchive log mode. Few major tablespaces are created with NOLOGGING option. We run ETL process.
My question is can I use RMAN though my tablespaces are created with NOLOGGING and DB is running in non-archive mode?
if Yes how?
Thanks

Test cold backup database in archive mode

Hello,
We doing every week a cold backup from Oracle database, us database is in archive mode.
We would like to test us cold backup in other server but the drive where we have to copy
the datafiles and logs and rollback are different on this server.
In the production server the oracle_home and the oracle_sid:
ORACLE_HOME=E:\oracle\product\10.2.0\db_1
ORACLE_SID=ENCY
and on the other server to test the backup are:
ORACLE_HOME=I:\oracle\product\10.2.0\db_2
ORACLE_SID=ENCY
Can somebody help me saying please the steps that I have to follow to restore the database in other server
to test if the last cold backup is fine?
My understand is copy the files(datafiles, log files, control files, pfile,...) in the new server, when everything is copied into new server,
I have to:
Modify the parameter CONTROL_FILES in the pfile
Mount the database and rename the datafiles and redolog files
Thanks.

When you attempt to startup the cloned database on the new server you will find that it needs recovery -- because it was taken in hot backup mode.
That is why you need to copy the archivelogs that are generated from the first archivelog after the first "alter tablespace begin backup" to the first archivelog after the last "alter tablespace end backup".
I see that you are also including a CREATE CONTROLFILE script.
You would run that at the cloned environment.
Then you would issue the RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL command to make the clone consistent.
You can, of course, use the same method to copy these archivelogs as you use to copy database files -- tar, cpio, tape, etc.

Looking for an advice in changing to archive mode my DB

Hello buddies!
I'm going to change a DB from no archive mode to archive mode. It's a RAc with ASM, 2 nodes.
What I need that somebody verify these steps and give me suggestions.
1. Login to one of the nodes (i.e. linux1) and disable the cluster instance parameter by setting
cluster_database to FALSE from the current instance:
ORACLE_HOME=/home/oracle/product/10.2.0/db
export ORACLE_HOME
ORACLE_SID=YAWIDB1
export ORACLE_SID
2. sqlplus "/ as sysdba"
SQL> alter system set cluster_database=false scope=spfile sid='YAWIDB1';
3. Shutdown all instances accessing the clustered database:
$ srvctl stop database -d YAWIDB
Using the local instance, MOUNT the database:
$ sqlplus "/ as sysdba"
SQL> startup mount
Enable archiving:
SQL> alter database archivelog;
Re-enable support for clustering by modifying the instance parameter cluster_database to TRUE from the current instance:
•     SQL> alter system set cluster_database=true scope=spfile sid=’YAWIDB1’;
•     Shutdown the local instance:
•     SQL> shutdown immediate
•     Bring all instance back up using srvctl:
•     $ srvctl start database -d YAWIDB
Since the archive destination is pointing to this path: Archive destination /home/oracle/product/10.2.0/db/dbs/arch
I think I should do the next steps to change that to ASM disk group, but in these steps I'm not sure. Please let me know If I'm wrong or correct? Or if I need to add something else.
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='+DG_DB1_ASM' SID='yawidb';
ALTER SYSTEM SWITCH LOGFILE;
The order of the complete steps, are correct or shoud be different?
Thanks for your comments and suggestions ;
Al

You do not need to change cluster parameter, see steps below:
On node1:

Noarchive mode to archive mode

Hi,
I'm trying to backup my database in online mode. I've 2 instances: BDPROD and BDPROD2. BDPROD is already in archive mode. I'm trying to change BDPROD2, but when I shutdown the database and run startup mount, I received the error: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor. After trying again, I received 2 new errors: ORA-24324: service handle not initialized
ORA-01041: internal error. hostdef extension doesn't exist
Anyone have any ideia for help me?
Thanks

Hi,
My Oracle runs in Linux.
My ORACLE_SID = BDPROD
My ORACLE_HOME = /usr/local/oracle/product/10.2.0/db_1
I've to change the ORACLE_SID?
It depends on how you are connecting to the database to do the shutdown/startup.
You should be doing it as a local connection. Log on to the linux server using the os account that owns the oracle installation, probably 'oracle'
set your environment variables correctly by using the oraenv utility as this:
oracle: . oraenv
That's "dot" "space" "oraenv"
You will be prompted for the correct ORACLE_SID.
After that you should be able to connect with a simple
oracle: sqlplus / as sysdba

False alarming for Archive mode status

Hi Friends,
In one of our development system(DB node) we are getting alerts as 'the Archive mode is in OFF state', but when i checked in DB level I can able to see the state as ON. Don't know what the problem is? Can anyone help me to resolve this issue?
Regards,
Palaniappan

Hi Palaniappan,
Please check the output of below command
SQL> SELECT LOG_MODE FROM V$DATABASE;
=> Output should be "NOARCHIVELOG"
SQL> ARCHIVE LOG LIST
=> output should have "DISABLED" under Automatic archival.

JSF 1.2 app is deployed only in exploded archive mode if JSF 2.0 facet used

Hi.
I'm developing JSF 1.2 + facelets application. The only way to configure eclipse WTP editors to properly handle xhtml pages is to install JSF 2.0 facet (there was facelets plugin before, but it was superseded by JSF 2.0 facet if I'm not mistaken). When application is deployed on WL, OEPE show message that JSF 2.0 applications can be deployed only in exploded archive mode.
Is there any way to make OEPE to believe that this application is based on JSF 1.2 (as really is)?
Regards,
Vadim.

Hi, Ian.
You are stating that it's a JSF 2.0 app by selecting that facet - the tooling relies on your facet selection to determine what features are available.Thought as much. Determining which JSF implementation will be active at deployment time looks like very complicated task and facet version is a reliable source of such kind info. Sadly :)
What "eclipse WTP editors" are you trying to configure?"HTML editor". Without JSF 2.0 facet it doesn't handle JSF taglibs' namespaces and EL expressions content assist/navigation.
The other option is to install JBoss Tools richfaces support, but for various reasons I'd like not to.
After using exploded deployment for a week now I see that it is not that slow as I initially thought (at least for a small project): JSP/XHTML changes picked up, class methods reloaded. Manual republishing is still not as fast as in case of the splitsource deployment, but it don't call it often.
Thanks.
