Database in Referral Mode

One of my databases is "stuck" in referral mode. When I set it through the console to accept reads and writes a few minutes later it reverts back to referral mode. Her is the message from the error log:
[13/Apr/2005:10:10:09 -0400] - WARNING<10265> - Replication - conn=-1 op=-1 msgId=-1 - Configuration warning This server will be referring client updates for replica l=emea,ou=internal,ou=people,dc=pwcglobal,dc=com indefinitely
The is a version 5.2 server service pack 2 on Solaris 8.

Hello,
First try by deleting the replication agreements and all the refferals on all your servers.
If it doesn't work disable replication, make sure that the changelog.db are deleted, and recreate.
Have a nice day

Database in noarchivelog mode, truncate command issued

Database in noarchivelog mode, truncate command has been issued how to restore the table?
FACTS:-
1. DB In noarchivelog Mode
2. Cannot enable flash back mode because of 1. above
3. No exports available
4. No backup's Available.
Any thoughts ?

Oracle Support/ Professional Services has a Data Unloader (DUL) and ORA-00600 has DUDE, both of which may be able to extract information from data files that are corrupted, where the control files are lost, etc.
These are not, however, cheap utilities. Unless the data itself is really valuable, it is generally not a viable option.

How to set the database in NOARCHIVELOG mode

hellow world,
I knewly joined this organization.
Our database is very small < 4GB data.
Database is running in ARCHIVELOG MODE.
since we are not keeping any physical backup, so I opted to run the datbase in NOARCHIVELOG mode.
For bringing the database in NOARCHIVE MODE, I simply changed the init.ora parameter LOG_ARCHIVE_START = FALSE and restart the database.
offcourse the archiving stopped, but to my strange after 30 to 40 minutes my all log files filled an error message is being displayed to the server, saying
log files are filled, waiting for the archiving, Oh my God, What has happened, All users came to my head, DATABASE HANGED, NOT RESPONSING.
SIR, MY QUESTION IS
WHAT FOR ALL LOG FILES WAITING?
when i am saying NOARCHIEVE than
please explain me, where i committed mistake. I am new to ADMINISTRATION.

1. Not keeping any physical backup is all the more reason to stay in archivelog mode.
2. You need to shutdown the database, startup mount, and issue 'alter database noarchivelog', the alter database open.

Problem running oracle 9i database in archivelog mode - database freezes

Greetings,
I recently needed to change a (test) database to archivelog mode to make online back-ups of this database. This posed no real problem although I seem to be unable to set the database to automatic archiving eventhough I edited the init.ora file (translation of the "archive log list" output between square brackets):
SQL> archive log list
Databaselogmodus Archiveermodus [Databaselogmode: Archivemode]
Automatisch archiveren Gedeactiveerd [Automatic archiving: Deactivated]
Archiveerbestemming O:\oracle\ora92\RDBMS [Archivedestionation: O:\oracle\ora92\RDBMS]
Oudste on-line logreeks 12306
Volgende logreeks voor archivering 12306
Huidige logreeks 12308
I added this to my init.ora file:
# Archvie Log Destinations
log_archive_start=TRUE
log_archive_dest_1=%ORACLE_HOME%\database\archive
log_archive_format="%%ORACLE_SID%%t_%s.arc"
However, this is not the real problem (maybe it has something to do with it, which is why I mention it aswell), the real problem is that my database freezes when the archive log file is "full". When the archive file reaches ~102.400Kb it just freezes up and I need to restart the database.
The following error is written to the alert_sid.log file:
Thu Apr 17 09:19:55 2008
Thread 1 cannot allocate new log, sequence 12309
All online logs needed archiving
Current log# 2 seq# 12308 mem# 0: O:\ORACLE\ORADATA\O\REDO02.LOG
The problem seems to be that the oracle service can't start a new logfile when the previous one is full. Does anybody know how I could fix this?
Thanks in advance,
Bram

Hello Maran, thanks for your quick response.
I added the output of archivelog list in the original post, but it's in dutch so here's the (loose) translation of the output:
SQL> archive log list
Databaselog mode Archive mode
Automatic archiving Deactivated
Archive destionation O:\oracle\ora92\RDBMS
Oldest on-line logsequence 12307
Next logsequence for archiving 12307
Current logsequence 12309
Maybe something that can help with the troubleshooting:
The archivelog file is written to O:\oracle\ora92\RDBMS but only AFTER the reboot, I've checked SYSTEM rights to the folder and it has full control.
Babu, thanks aswell for your quick response.
The location exists and space is available but the database doesn't seem to load (that part of) the ora.init file because the output of archive log list still refers to %ORACLE_HOME%\rdbms instead of %ORACLE_HOME%\database\archive.
I've now executed alter system archive log all; and am executing the import where the database usually freezes to see if it still happens. So far I already had this written to the alert_sid.log file after executing the command:
Completed: alter database open
Thu Apr 17 10:00:11 2008
ARCH: Evaluating archive log 1 thread 1 sequence 12307
ARCH: Beginning to archive log 1 thread 1 sequence 12307
Creating archive destination LOG_ARCHIVE_DEST_1: 'O:\ORACLE\ORA92\RDBMS\ARC12307.001'
ARCH: Completed archiving log 1 thread 1 sequence 12307
ARCH: Evaluating archive log 2 thread 1 sequence 12308

Creating archive destination LOG_ARCHIVE_DEST_1: 'O:\ORACLE\ORA92\RDBMS\ARC12308.001'
ARCH: Completed archiving log 2 thread 1 sequence 12308
And new log files were written to the directory (O:\oracle\ora92\RDBMS) and this time I didn't have to reboot for it to happen. Both were 100mb files without the database actually doing all that much though.

Hello,
Did you made sure no transactions like restore logs were running when you stopped SQL server service or agent .I have seen in SQL 2000 an abrupt stop of SQL Server agent when its doing a process can sometimes force database in suspect mode.
I would like you to get your disk analyzed by vendor ASAP for any fault in disk at first go it seems to me an underlying hardware issue.
Please can you check errorlog and event viewer to find out any possible cause for database going into suspect mode
I always suggest to use Backup and restore method of recovery to get out from suspect database problem.If you dont have then you can move with DBCC Checkdb and various repair options but be sure
DATA LOSS might be possible when you use repair allow data loss and repair_rebuild removes constraints.
hope this helps

How to use Derby database in embedded mode in WebLogic 12c?

I have a JavaEE-6 application that uses Derby database in embedded mode. It uses JPA for persistence. Everything works fine in Glassfish but now I am trying to port it to WebLogic 12c and having issues setting up Derby database in WLS in embedded mode. The derby setup in WLS asks for Host/port and does not have the embedded mode option. Any help is appreciated.

I'm pretty sure this is the wrong forum. "Oracle Application Server" is iAS, not WebLogic.

Database in suspect mode

i was going through this article about recovering a database in suspect mode :
http://www.mytechmantra.com/LearnSQLServer/Repair_Suspect_Database_P2.html
in the article the error seems to indicate corruption in the log :
Error: 9003, Severity: 20, State: 9. The log scan number (189624:16:2) passed to log scan in database
'BPO' is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf
if the corruption is in the log, then is not the logical solution to bypass the recovery process and then truncate the log with no_log option and then bring the database online?
and dbcc checkdb (<db>,repair_allow_data_loss) repairs the data pages or the log pages?
and any other options/ways/articles about bringing a suspect database online?
appreciate the insights.

datafile corruption : put db in emergency mode / put db in single user mode / dbcc checkdb with REPAIR_ALLOW_DATA_LOSS/ dbcc checkdb on database
again/put db back in multi user mode.
There is no need to do this. This is totally not required.
You can
Switching the database to the Simple recovery model
Performing a checkpoint (which should clear the active log as long as nothing else requires the log to be kept active)
Switching back to the Full recovery model
Reestablishing the log backup chain by performing a full or differential backup
Or you can rebuild log as already pointed in my reply.
Or you can restore from known valid backup.
There is no need to move data as well because actually its not related to data.

Running a physical standby database in noarchivelog mode

Primary Database: 2 node rac cluster, 11.2.0.2 GI and RDBMS
Standby Database: single instance 11.2.0.2
OS: AIX 7.1
Hello,
I'm in the process of implementing a data guard standby system. To make this system simpler to admin, I want to run the standby database in NOARCHIVELOG mode. This standby is used only as a mirror of production (to be copied to a 3rd site for separate user activity) and will never be switched to active mode. Maintaining another set of archive logs seems to be redundant to me and another point of failure, so I want to disable archiving. I wanted to ask if any of the DG experts on the forums have ever had experience with this? Does anyone know if this is recommended? I've searched the Oracle Data guard documentation online... it says that the primary obviously needs to be in archive mode, but I'm not seeing anything specific about the standby. Please let me know if anyone has experience with this.
Thanks

Hello again;
If this is the case, then I have nothing to worry about here. Does that sound right to you?Yes.
For this :
b) monthly, shutdown this system and copy it to a 3rd site to host a separate set of business activityI would consider RMAN Duplicate in which case you may avoid the shutdown.
And for this :
resync the "mirror" with productionAll you have to do if DEFER the primary to the standby, then ENABLE and Data Guard will catch up.
--- Will post a detailed example here in a moment.
Right at the first of the year they wanted to work on our Primary server room ( Power ). What I did was switchover to the Standby but I kept log_archive_dest_state_2 on the new primary set to DEFER. Then I shutdown
all the databases at the Primary site. At the end of work two days later I started the databases at the Primary site in standby mode. Switched log_archive_dest_state_2 to ENABLE. When the databases were back in SYNC
I did another switchover and it was done. I used TAF and none of the users even noticed.

Starting Physically Standby Database in Mount Mode

Hi All
I have configured Data Guard using Oracle 10g 10.2.0.4.0 (64 bits) on Windows 2008 Server (64 bits) Release 2 Enterprise.
Data guard configuration was OK as the message from "Enable Configuration DG1" was "SUCCESS" for both
Primary and Standby Database. I have also set both Databases and TNS to start Automatically whenever Windows Starts.
The Problem is as long as the Standby Server is running, there is No issue.
But when we Restarts the Backup Server, Physically Standby Database is Started and TNS is also Started,
but Archives are not received until I physically do the following steps so that it can received the Archives.
SQL> startup nomount;
SQL> alter database mount standby database;
SQL> alter database recover managed standby database disconnect from session;
Is there a way to start Physically Standby Database in Mount mode when windows started.

ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode

Hi All,
Need help from the gurus.
Currently we are in state unable to do anything.
Was using a database and all of a sudden it crashed. Tried to mount the database, open it, it failed. Also tried the recover and alter database open, even that failed. Errors are as follows.
Errors in file e:\oracle\product\10.2.0 \admin\devrevdb\bdump\devrevdb_p000_2620.trc:
ORA-00603: ORACLE server session terminated by fatal error

ORA-00449: background process 'DBW0' unexpectedly terminated with error 1242
ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
In my spfile, the administrator has set only two control files and there is no mirroring and hence do not have another control file that will help me boot the db.
Please let me know how I should go about it. I am only a timebeing person trying to carryout a db activity. Any help would be of great help.

Hemant,
thanks for the reply.
I tried the way you suggested and it threw an error.
ORA-01145: offline immediate disallowed unless media recovery enabled
I searched and found that an additional tag of drop needs to be added to the command which you suggested.
ALTER DATABASE DATAFILE '<filename>' OFFLINE DROP.
i don't know what will the drop command have an effect ?
i have copied the data file to another location. Since i don't know much, i just want to be sure of what im doing.
if the above command is successfull, will it drop the datafile or the tablespace and i can no more use it. How can i use the copied datafile.
Thanks,
Sachin

Oh, ok Vijayaraghavan K.
Thx for u help.
And about the users ?
i need to create the "same" user in another machine ?
For example:
In this machine i using the "system" user, where i have my tables.
Another machine, when i restore, my tables will go to the "system" user too? or i can choice? or i need to create one?A true backup is a copy of the data files at the file/block level. The restore is therefore a restore of the data files/blocks. Applying the redo (archive logs) is also done at the block level. None of that knows or cares (or needs to know or care) about logical objects (such as users, tablespaces, tables, rows, etc) within the database. so if you do a proper restore, you are restoring files to a consistent state and thus everything that was defined within those files will be there when restored.

Changing database to noarchivelog mode during impdp

Hi Guys,
I am using Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production on RHEL5.
I am in the middle on the impdp and I want my database to run on noarchivelog as it creates a lot of archivelogs.
Will it be proper if I stop the import:
e.g Import> STOP_JOB=IMMEDIATE
and shutdown the database put the database on noarchivelog mode.
then opne database and
impdp hr/hr@mydb ATTACH=myfulljob Will these work fine?
Or should I execute:
alter system archive log stop;
Please Help !!!!!!!!!!!

Vinod Dhandapani wrote:
Running the database in Noarchivelog mode means you should be ready to lose data incase there is any crash. I would recommend you to change the size of the redologs so that it will not create frequent archivelogs. Which does nothing about the space required for the archivelogs. If you are generating redo at the rate of 1gb/hour, you will consume archivelog dest space at the rate of 1gb/hour. Doesn't matter if those files are 10mb each or 100mb each.
If space is the problem then use a shell script to move the archivelog to another location (Tape)....And hopefully that shell script is invoking rman to do the work, so that in the event of recovery, rman will know that backups were taken and where they are located.

Incase you want to convert the database from archivelog to noarchivelog, follow the steps provided in the following link.

Error message in Command line (cannot mount database in EXCLUSIVE mode)

Hello Experts
I'm new in Oracle and trying to connect to my database though SQL command line. After I login as SYS I user I get the message that 'connected to idle instance'. Then I use “STARTUP” to connect to database. Now from my understanding it should mount the database and open it as well. But it does'nt happens.Instead I get the message 'cannot mount database in EXCLUSIVE mode' . I'm not sure why it can't mound the database and what should I do to make it working. Please can somebody show me how to make it working again. Here are the details about my problem
Enter user-name: SYS as SYSDBA
Enter password:

Thank you so much for both of you. I've checked everything. All looks fine to me and then i tried to connect though SQL and it worked. Now what I've notice that this time I didn't start Enterprise Manager only I started the listner and then start sql it worked. Does this means that I can't use both SQL and EM at a time together?

Database in Emergency Mode

Hi All.. i have had one database was in suspect mode and i have changed the status to Emergency Mode and i have run the DBCC checkdb and command didn't gave any error.. after this i have tried to change database to Single_user mode, but command running
successfully, but database status is still showing as Emergency mode only.. i have tried for multi_user mode too..
Also, i have tried to run the command to bring online, but command running for long time with Suspended status..
Could anyone help me on this??

Hi Balajik,
"Also, i have tried to run the command to bring online, but command running for long time with Suspended status.."
In addition to other post, please check the following things.
1. Run sp_who2 to check that if there is blocked process. If blocked process exists, run “KILL <spid>“ to kill it.
2. Make sure that there are no connections to the database from other applications. You can run the below scripts to find connections.
USE master
SELECT * FROM sys.sysprocesses WHERE dbid = DB_ID('DatabaseName')
3. You might need to stop and start SQL Server Service using SQL Server Management Studio, then check if you can set the database online.
Besides, to recover database which is in emergency mode, you can review the following similar thread.

Database in Archivelog mode

Hi
All,
I have oracle 9.2.0.6 at my workplace.right now my database running in ARCHIVELOG MODE. I want to set it to NOARCHIVELOG MODE.
can I do on the fly? in other way, Do I need to shutdown and restart database?
Any help will be appreciated.
Thanks,
Vishal

Hi,
Issue the following commands to put a database into NOARCHVELOG mode:
1) Take Back up of Present SPfile by creating pfile
create pfile from present spfile.
2) Shutdown the database by SUTDOWN IMMEDIATE.
3) Take Cold backup of the database.
4) Change the parameter in the pfile.
log_archive_start = FALSE
#log_archive_dest_1 = 'LOCATION='Your location'
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 ARCHIVELOG;
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE OPEN;
NOTE 1: Remember to take a baseline database backup right after disabling archivelog mode. Without it one would not be able to recover.
