DOUBT IN CRETAING DATAFILES
Hello,
i have one doubt in creating datafile if suppose i have created a TABLESPACE T1.
with DATAFILE X.
CREATE TABLESPACE T1 DATAFILE 'D:\ORACLE\ORADATA\ORCL\X1.DBF' SIZE 1024M
Now if suppose that i wan't to increase the tablespace size fot that i have two options
1.resize the existing datafile
or
2.Adding another datafile
my doubt is which is the best option in the above two
regards,
lakshmi
In your case, it doesn't matter you add a new datafile or increase the size to an existing datafile.
However, if the size of an existing datafile is notable high, it is better to add a new datafile.
As it will prevent single point failure and also increases your backup and recovery timing.

Doubt about transfering datafiles
sir/madam,
as a DBA, i had a requirement for converting a datafile from one> tablespace to another. but for my surprise, i couldn't do it. from user or DBA point of view, i appreciate all the new features and capabilities of Oracle. but this one was quite amazing that how
could such a feature be overlooked. That is, its possible to move
objects between tablespaces(here i mean, alter table ...move...).
but i couldn't move datafile between tablespaces. recently i had
a requirement, something like this.
Database is in noarchivelog mode. i have users tablespace with one
datafile u1.dbf. i created one other datafile u2.dbf for some temporary
reasons.after my work i offline dropped the datafile(u2.dbf) with alter
database..command(assume that the tablespace is offline). but now the
datafile(u2.dbf) is still in recover status from v$datafile(because database
is in noarchivelog mode). when i try to online the tablespace, its saying
that datafile is not able to be locked/found as error and action says to
drop the tablespace itself. but here u1.dbf datafile is having all the users
information in which case, i cannot drop the tablespace. here, my
requirement is to move the datafile from users to some other tablespace to
drop it. but i'm not able to drop it.
i'm really confused on what to do with this. please recommend necessary
suggestions so that i can overcome this problem. as a DBA i think this one
is quite a good question. i request you to please suggest me a solution as
soon as possible.
thank you
sivamurugesh arumugam(DBA)Donald has your solution. As far as the "feature" of moving a datafile from one tablespace to another, this makes no sense. Datafiles are the physical (operating system level) implementation of tablespaces. The fact that you can have multiple datafiles per tablespace was originally intended to overcome file size limites due to the size of hard disks (before we could span volumes with RAID 5). Now this construct allows us to have tablespaces (and therefore tables) which are larger than the file size limit of the operating system. Never treat a datafile as a independent entity. It is part of a tablespace. It may contain any part of any table within the tablespace. Always treat all datafiles of one tablespace as a logical unit and you won't break anything.

Committed trans in datafiles in oracle 10g
Hi DBA gurus,
I have a small doubt : If the datafiles contains both committed and uncommitted data then howcome there is only committed trans and uncommitted transx. will be rollbacked.
I know that while instance recovery SMON automatically does that but is there any other activity that triggers only committed data in datafiles or what initiates Instance recovery.
Thanks in advance.
Regards,
Shikha RaniIf the database is running normally, then yes, the blocks of data on disk will contain committed and uncommitted transactions. (I think I confirmed that in my first sentence of my earlier reply).
DBWR flushes buffers to disk on its own schedule, paying no regard to whether their contents are committed or uncommitted.
But DBWR cannot write a block to disk until the redo which is associated with dirtying it has been written.
That redo will be written whether or not there has been a commit.
Once you have a dirty block on disk, and the redo needed to un-dirty it by transaction recovery, everything is safe and recoverable.
I thought I should add to my answer:
Suppose you have a transaction that starts at time A and runs until time K.
At time D, there is a log switch, which causes a checkpoint, and therefore at time D, blocks dirtied at time A, B, C and D are now all written to disk, including undo generated by dirtying the blocks
At time E, that transaction continues and dirties more blocks.
At time F, there is another log switch, so blocks at time D, E and F are now all on disk (plus their corresponding undo)
At time H, there is yet another log switch, so blocks at time G and H are now written to disk (along with the undo)
This database is not in archivelog mode, and you've just switched all the way around the redo logs, and the transaction still hasn't finished or committed yet.
So now you are still dirtying blocks at time I and J, and the redo from that is being written into the current redo log, over the top of the redo that was generated at times A->D. Redo from time A-D is no longer available. But that's OK, because the dirty blocks from that time ARE safe on disk, and the undo needed to clean them up is also safe on disk.
Now at time K, you have an instance crash.
SMON won't start the transaction from scratch. It doesn't need to. It simply starts re-dirtying blocks from time I and J.
When it's reached time J, it now sees there's no commit, and therefore knows to roll back the entire transaction. It can roll back the blocks from time I and J using undo re-created the redo from the current log was being re-played. It can roll back the blocks from time A ->H because the undo for them is already available from the data files themselves, saved at the time of the various checkpoints. -
Need to test if a column have unique values or not
Hi all,
in ETL process I need to check if some cols have unique values or not using sql or plsql.
Suppose we need to load a big file data with external table initially and then test if values
on one or more columns have unique values in order to proceed with ETL process.
What is the faster test I can execute to verify that a column have unique values or not?
It's better for the ETL performance, use:
a. techniques regard constraints like described on Ask tom forum
"ENABLE NOVALIDATE validating existing data"
(Ask Tom "ENABLE NOVALIDATE validating existing da...")
b. "simply" query on the data?
like this:
select count(count(*)) distinct_count,
sum(count(*)) total_count,
sum(case when count(*) = 1 then 1 else null end) non_distinct_groups,
sum(case when count(*) > 1 then 1 else null end) distinct_groups
from hr.employees a
group by A.JOB_ID
c. use analytics function?
d. use some feature directly on external table?
Bye in advanceHere is the example to handling the errrs using LOG_ERRORS into concept. You will check this and let me know if any doubt you have

Reg: AUTO Exend for tablespaces
Hi,
I want to have a discussion with the AUTO EXTEND option for Tablespaces in oracle 9.2.0.4.0.
Actually i am having one INDEX or USERS tablespace and for eg if index is having 15 datafiles till now and 15th datafile in that INDEX is running with AUTO EXTEND option.
I created with a SIZE of 3000mb and next extent as 500 mb.When the space is filled with 3000 mb, i believe it will be using the NEXT EXTENT 500 mb.
So here what i want if that NEXT Extentis also filled and upto how much space and to how much extend this AUTO EXTEND OPTION will be useful.
What is the MAX size for this AUTO EXTEND and where it will grow if those spaces are filled ?
When can I add another datafile for that without causing any problem ?
I am having another doubt on these datafiles already filled i.e 14 datafiles which
are stored in database ? How long those datafiles in tha INDEX tablespace will be useful for future ...as we are going on adding the datafiles at some extent space problem will come .So how to analyse that and what are the precautions we have to take?
Sorry if am asking any basic or silly question over here....
Please Clarify my above confusion....
Thanks in Advance...

Extend will allocate max space of your hard disk -
After did a switchover(DataGuard), on my current primary database I did a level 0 backup RMAN and it did not end due to an error with an datafile that needs recover, specifically the datafile 2 (sysaux tablespace). The last level 0 backup I have is 9 days ago. The first thing I do was restore the datafile and try to recover it.
RMAN> run{sql 'alter database datafile 2 offline'; restore datafile 2; recover datafile 2;}
The second step (recover) show me the following error:
unable to find archived log
archived log thread=1 sequence=1
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN-06054: media recovery requesting unknown archived log for thread 1 with sequence 1 and starting SCN of 1757
I appreciate any help, thank you.Dear user12100209,
Please see the error message;
RMAN-06054: media recovery requesting unknown archived log for thread string with sequence string and starting SCN of string
Cause: Media recovery is requesting a log whose existence is not recorded in the recovery catalog or target database control file.
Action: If a copy of the log is available, then add it to the recovery catalog and/or control file via a CATALOG command and then retry the RECOVER command.
If not, then a point-in-time recovery up to the missing log is the only alternative and database can be opened using ALTER DATABASE OPEN RESETLOGS command.So what i am thinking is that is happening because of a missing archivelog metadata(information) in the standby controlfile.
Below link may give you a general information;

Hope That Helps.

Dear Friends,
Please clarify wheteher the below method is correct to confiure ASM disks for Datafiles and FRA
Partitions provided by IT team for OCR and Voting Disk
/dev/sda1 - 150 GB (For +DATA)
/dev/sda2 - 100 GB (For +FRA)
OS : RHEL 5.6 (64 Bit)
kernel version = 2.6.18-238.el5

1) Install the RPM's for ASM
rpm -Uvh oracleasm-support-2.1.7-1.el5.x86_64.rpm
rpm -Uvh oracleasm-2.6.18-238.el5-2.0.5-1.el5.x86_64.rpm
rpm -Uvh oracleasmlib-2.0.4-1.el5.x86_64.rpm
2) Configure ASM
/etc/init.d/oracleasm configure

/etc/init.d/oracleasm createdisk DISK2 /dev/sda2
4)/etc/init.d/oracleasm status
5)/etc/init.d/oracleasm scandisks
6)/etc/init.d/oracleasm listdisks
7) Nothing to perform on Node2
8) In dbca choose ASM and map the DISK1 for datafiles and DISK2 for FRA
Please confirm the above steps are right?if not please clarify
If DBCA ->ASM doesn't discover my disk then what should be the Discovery path i have to give?
Please refer any document / Metalink ID for the above complete process
Can i have ASM and oracle DB binary in the same home

RMAN-06023: no backup or copy of datafile 2 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restoreSO MY QUESTION OR DOUBT IS WHY AT THE END IT FAILS THAT THERE IS NO BACKUP FOR DATAFILE 1,2,3,4 ??? AS WE CAN SEE ABOVE IT IS PRESENT IN MY BACKUPSET ??
ANY IDEA /HINTS/TIPS ?
I searched on google and somebody mentioned to a similar case that it could be a problem with 'CONFIGURE CONTROLFILE AUTOBACKUP OFF' where as in my case i have set it to 'CONFIGURE CONTROLFILE AUTOBACKUP ON'
Somehow looks like that the control file is not having latest backup info ... :-( I already took a fresh backup 2 times and landed up in same issue.. not sure where i am doing a mistake.
Regards
LearnerNo replies ... :-(
Meanwhile i also looked in the trace file folder to see if there are any clues. here goes the content of alert_log.file

I have a doubt on retention policy. Can someone advise me the difference between
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; AND
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 5 DAYS;
Say if I do a cold backup everyday and I want RMAN to keep backups only for last one day so I can recover till yesterday, what retention settings will I configure.Hi Daljit,
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 3 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL DEVICE TYPE DISK MAXPIECESIZE 1 G;
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oraprd/product/10.2.0/db_1/dbs/snapcf_jerry1.f'; # default
and the script is
run {
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
delete noprompt expired archivelog all;
shutdown immediate;
startup mount;
backup database plus archivelog;
alter database open;
exit; -
Datafiles Mismatch in production & disaster recovery server
Datafiles Mismatch in production & disaster recovery server though everything in sync
We performed all the necessary prerequisites & processes related to DRS switchover successfully also our DRS server is constantly updated through logs application in mount state whan we opened DRS database in mount state it opened successfully however when we issued command
Recover database
It dumped with foll errors:
ora-01122 database file 162 failed verification check
ora-01110 data file 162 </oracle/R3P/sapdata7/r3p*****.data>
ora-01251 unknown file header version read for file 162
as I do not remember the exact name now
However upon comparing the same file at production(which was now in shutdown state) the file sizes were mismatching so we went ahead to copy the datafile from production to DRS in database shutdown state at DRS through RCP utitlity of AIX 5.3 since our Operating system is AIX 5.3
Though this remote copy was success
we again started database in mount state & issued command
Recover database
But still it dump the same error but now for another datafile in DRS
I mean I would appreciate if somebody could point out that despite our DRS was constantly being updated through our Production in terms of continuous log application before this activity logs were sync in both the systems also origlos,mirrorlogs & controlfiles were pulled from production system as it is infact the whole structure was as replica of production system , then why did datafile sizes mismatch??

SAP version :- 4.7
WAS :- 620
Database :- Oracle 9.2
Operating system :- AIX 5.3I am in a process of DR Planning.
My present setup :
O/S : HP-UX 11.31
SAP ECC 6
Oracle 10g Database.
I know about dataguard and i have implemnted same on our other application but not for SAP.
I have ame doubts and I request you to please guide me for the same.
1. SAP License key -- it required hardware key. So will i have to generate license key another hardware key i.e. for machine where standby database.
2. Database on standby site will be in manage recovery mode. Will I have to make any changes or any other file realted to SAP on standby host ? (some i know such as I upgrade SAP kernal, same i have to upgrade at standby host)
Will you give me some link related to document for DR -
Hi All,
I would like to share my doubts about ASM and FRA(Is this section the right one to put this doubt?)...
*I know about the retention policy in FRA and that files will be deleted automatically and that production datafiles should NEVER be moved to the FRA area.
But,
Using ASM I have two diskgroups, for data and FRA. FRA area is oversized (5G normally used of 300G total,backups are not placed here...) can this area(FRA) be used temporarily to guard some datafiles(data diskgroup running low...)?Which is the risk?Or Is it better to just put the datafiles outside the diskgroups?
Can you share histories (crash?,data deletion?duh..)
Using a test environment(no-ASM,no-RAC) I put a datafile in the FRA area but the view V$FLASH_RECOVERY_AREA_USAGE did not update...Is it normal?No?How refresh it?I already use crosscheck's rman..
Which is the best way to resize the FRA diskgroup and remanage the space to the data diskgroup?(external redundacy, FRA diskgroup is listed to have 1T by Enterprise Manager, db_recovery_file_dest_size=300G...)
Oracle DB version 11.2.0.3.0(RAC)
Linux version: 2.6.32.el6
Using Oracle ASMUsing ASM I have two diskgroups, for data and FRA. FRA area is oversized (5G normally used of 300G total,backups are not placed here...) can this area(FRA) be used temporarily to guard some datafiles(data diskgroup running low...)?Which is the risk?Or Is it better to just put the datafiles outside the diskgroups?

Regular datafiles are not taken into account in V$RECOVERY_AREA_USAGE. Even if you use rman "catalog recovery area", rman will skip them. Therefore database will not remove them.

You can move disks between diskgroups. Or you can temporary disable db_recovery_file_dest (putting logs and other files to new destination), remove diskgroup, resize LUN and create new diskgroup. -
Doubt about database point in time recovery using rman
Hi Everyone,
I have been practising various rman restore and recovery scenarios . I have a doubt regarding database point in time recovery using rman. Imagine i have a full database backup including controlfile scheduled to run at 10 PM everyday. today is 20th dec 2013. imagine i want to restore the database to a prior point in time ( say 18th dec till 8 AM). so i would restore all the datafiles from 17th night's backup and apply archives till 8 AM of 18th dec . in this scenario should i restore the controlfile too from 17th dec bkp ( i am assuming yes we should ) or can we use the current controlfile ( assuming it is intact). i found the below from oracle docs.
Performing Point-in-Time Recovery with a Current Control File
The database must be closed to perform database point-in-time recovery. If you are recovering to a time, then you should set the time format environment variables before invoking RMAN. The following are sample Globalization Support settings:
NLS_LANG = american_america.us7ascii
NLS_DATE_FORMAT="Mon DD YYYY HH24:MI:SS"
To recover the database until a specified time, SCN, or log sequence number:
After connecting to the target database and, optionally, the recovery catalog database, ensure that the database is mounted. If the database is open, shut it down and then mount it:
2. SHUTDOWN IMMEDIATE;
3. STARTUP MOUNT;
4.
Determine the time, SCN, or log sequence that should end recovery. For example, if you discover that a user accidentally dropped a tablespace at 9:02 a.m., then you can recover to 9 a.m.--just before the drop occurred. You will lose all changes to the database made after that time.
You can also examine the alert.log to find the SCN of an event and recover to a prior SCN. Alternatively, you can determine the log sequence number that contains the recovery termination SCN, and then recover through that log. For example, query V$LOG_HISTORY to view the logs that you have archived.
RECID STAMP THREAD# SEQUENCE# FIRST_CHAN FIRST_TIM NEXT_CHANG
1 344890611 1 1 20037 24-SEP-02 20043
2 344890615 1 2 20043 24-SEP-02 20045
3 344890618 1 3 20045 24-SEP-02 20046
Perform the following operations within a RUN command:
Set the end recovery time, SCN, or log sequence. If specifying a time, then use the date format specified in the NLS_LANG and NLS_DATE_FORMAT environment variables.
If automatic channels are not configured, then manually allocate one or more channels.
Restore and recover the database.
The following example performs an incomplete recovery until November 15 at 9 a.m.
RUN
SET UNTIL TIME 'Nov 15 2002 09:00:00';
# SET UNTIL SCN 1000; # alternatively, specify SCN
# SET UNTIL SEQUENCE 9923; # alternatively, specify log sequence number
RESTORE DATABASE;
RECOVER DATABASE;
If recovery was successful, then open the database and reset the online logs:
5. ALTER DATABASE OPEN RESETLOGS;
I did not quiet understand why the above scenario is using current controlfile as the checkpoint scn in the current controlfile and the checkpoint scn in the datafile headers do not match after the restore and recovery. Thanks in Advance for your help.
Thanks
satyaThanks for the reply ... but what about the checkpoint scn in the controlfile . my understanding is that unless the checkpoint scn in the controlfile and datafiles do not match the database will not open. so assuming the checkpoint scn in my current controlfile is 1500 and i want to recover my database till scn 1200. so the scn in the datafiles (which is 1200) is not not matching with the scn in the controlfile(1500). so will the database open in such cases.
Thanks

Dear all,
Please help me regarding this i am very much confused.....
I had couple of doubts in dataguard concepts.
1)When archive log is transferred from primary to standby ,
a.Whether DBWR will be in active state or not in standby server.To write the contents in the archived redo log files which came from the primary to the datafiles of the standby server.
b.I am using online redo logs in the standby server not standby redo logs , whether online redologs in the standby server will have any effect in shipping of redologs from the primary database,
c. In my standby database online redo logs state is changing between CLEARING AND CLEARING CURRENT.How standby server redologs will change it state,
Regards,
Vamsi.Hi again,
They are not used in a physical standby database. They exist in order to be used in a case of opening the standby database read-write (failover/snapshot standby). Here what documentation says:
Online redo logs
Every instance of an Oracle primary database and logical standby database has an associated online redo log to protect the database in case of an instance failure. Physical standby databases do not have an associated online redo log, because physical standby databases are never opened for read/write I/O; changes are not made to the database and redo data is not generated.
Create an Online Redo Log on the Standby Database
Although this step is optional, Oracle recommends that an online redo log be created when a standby database is created. By following this best practice, a standby database will be ready to quickly transition to the primary database role.

How to recover database SYSTEM datafile get corrupt ?
Database is in ARCHIVELOG mode, and the datafile belonging to SYSTEM tablespace gets corrupted. Up to what point can I recover the database ?
A. Until last commit.
B. Until the time you perform recovery.
C. Until the time the datafile got corrupted.
D. You cannot recover the SYSTEM tablespace and you must be re-create the database.
and 1 more doubt :
If redologfiles are not multiplexed and redolog blocks get corrupt in group 2, and archiving stops. All redolog files are filled and database activity is halted.
DBWR has written everything to disk. What command can be used to proceed further ?
A. recover logfile block group 2;
B. alter database drop logfile group 2;
C. alter database clear logfile group 2;
D. alter database recover logfile group 2;
E. alter database clear unarchived lofile group 2;
Edited by: user642367 on Sep 18, 2008 8:45 PM1. A. Since the DB is in archivelog mode, so you can always restore and recover the whole DB including system tablespace datafile till last SCN generated provided the redo record is available in archive/online logfiles.
2. E. Since only redolog is corrupted so archiver won't proceed and hence a db hang is obvious, So, in order to proceed further you need to clear online (un archived log file) and then db will work as usual. Care should be taken that you must take a full backkup of DB(cold backup wherever feasible) as soon as possible after issuing this command. As now you don't have redo info in archivelog files to recover the db in case of a crash.
Please go through Oracle 10g DB Administrators guide (available on OTN) for more details.

Instance terminated because of one datafile...
Hi All,
I am using oracle database 10.2.0.4 on windows server 2003(32bit), now there are 4 instance running. Problem with one instance "orcl" and the problem is every weekend this database is terminated. and I found the below error in alert.log file:

I try to findout this tablespace and datafile status:

and the size of the tablespace's datafile are;
TEST_DATA=31.9G
TEST_DATA2=26.8G
TEST_DATA3=4.8G
Can any one suggest me what would be the cause behind the instance termination?
Thanks,
Jigisha...Hi Hemant,
there is nothing running at OS level as I make confirmed with OS Admin.
or that is accpetable if any thing run at os/db level and lock a file but its actually terminate the instance...if you see above my paste content.
only one doubt which I have and that is this user "TEST_DATA" having default tablespace is "TEST_DATA". This tablespace having 3 datafiles. when I import this user during import operation it gives error for full this test_data.dbf , so I resize test_data.dbf to 34G and resume import activity.
when again import gives error I added one another datafile i.e. test_data2.dbf which is also in size of 26.8G.
but when I found my Instance in Down mode I added 3rd file TEST_DATA3.dbf(with the consideration that might be some max limit of 8192 blocks on 32bit windows like 32G/34G dbf file size limit) and its size is 4.8G currently.
so as I already added other datafiles to this tablespace then why it refers to 1st datafile only during some activity and terminate the instance?
suggest me if you have some thing...
