How to multiplexing control files in ASM instance???

Hi Folks
I have an Oracle DB10g R2 with ASM in which the unique control file is in one group of ASM.
My question is how to multiplex the controlfile and redo logs???
Very thanks,
Wilson

Hi, you can use the OMF feature of ORACLE to move the controlfile into the ASM.
1. you create a backup controlfile: ALTER DATABASE BACKUP CONTROLFILE TO '/home/oracle/control.bac';
2. you specify the locations:
- ALTER SYSTEM SET db_create_online_log_dest_1='+ASMGROUP1'; -- RMAN will restore one mirror of the controlfile in each of these locations!
- ALTER SYSTEM SET db_create_online_log_dest_2='+ASMGROUP1';
ALTER SYSTEM SET db_recover_file_dest='+ASMGROUP1'; -- this will make RMAN restore the controlfile in the flash_recovery_area!
3. you create a pfile from spfile:
- CREATE PFILE FROM SPFILE;
4. you archive the current redolog:
- ALTERSYSTEM ARCHIVE LOG ALL;
and SHUTDOWN IMMEDIATE
5. you edit the pfile by removing the entry for CONTROL_FILES!!!
- and after this: CREATE SPFILE FROM PFILE;
6. you use RMAN to restore the controlfile in the ASM:
RMAN> STARTUP NOMOUNT;
RMAN> RESTORE CONTROLFILE FROM '/home/oracle/control.bac';
RMAN> ALTER DATABASE MOUNT;
RMAN> RECOVER DATABASE USING BACKUP CONTROLFILE;
RMAN>ALTER DATABASE OPEN RESETLOGS;
Hope this helps,
Lutz

Multiplexing control file

How to multiplexing control file in oracle 10g?

Hi,
Two ways are to MULTIPLEXING CONTROL FILE.
If you are using PFILE..
1. Set a Parameter... CONTROL_FILE= <ORACLE_BASE>\ORADATA\ORCL\CONTROL1.CTL,<ORACLE_BASE>\ORADATA\ORCL\CONTROL2.CTL
If you are using SPFILE..
2. Then use, ALTER SYSTEM CLAUSE to change the paremeter value dynamically.
for ex> ALTER SYSTEM SET CONTROL_FILE=<ORACLE_BASE>\ORADATA\ORCL\CONTROL1.CTL, <ORACLE_BASE>\ORADATA\ORCL\CONTROL2.CTL
Thanks.

Please provide a procedur in detail.
Thanks

Hi damorgan & Friends,
I could not find some infomration to add control into ASM . I can do this job( see below procedure) in no ASM .
My question, our database locates at ASM and control file with a system auto-number ( fully qualified filename ) as
+DATA1/SALE/controlfile/current.256.690290159
How do I physical copy and rename other 2 contril file in directory and modify location in pfile?
I saw some paper to use request as an alias (such as +dgroup2/control/ctl.f). i can not image to copy/rename control.
Please help me!!
Thanks
Jim

How to create redlog and control file at ASM in linux RAC

Hi Experts,
I will to maintance a oracle 10g database at ASM as RAC iin linux red hat.
i am a new person with some question.
nornally speaking, oracle recommadition for oracle 10g database as
create 3 copy fills for control file
create at least 2 redo log with mirror files in system.
However, I checked find
redlog file is at FRA place +FLSdisk1 and no mirror
control file is at FRA place--+FLSDISK1/
datebase file at ‘+DATA1/
There are no mirror for relog.
Go to EM, I also could not find place to enter file name.
We use ASM to hold database to support RAC.
Do i need to create redlog file as
ALTER DATABASE ADD LOGFILE GROUP 1 ('+FLSdisk1/sale/onlinelog/REDO01.LOG','+FLSdisk1/sale/onlinelog/REDO01_mirror.LOG') SIZE 1000M reuse;
my boss told me that ASM is reliable.
Do you need to creat more directory to arrange redlog and control files in ASM for RAC system?
FRA is a good place to store control file and redlog file ?
Thanks
JIM

ASM is reliable but a smart DBA is very careful. If ASM is doing mirroring this is like RAID doing mirroring. What happens if you accidentally delete one copy ... the other one disappears instantly. Not a good idea.
With respect to redo logs you need a minimum of three groups, two members, and one thread per instance. So a 2 node cluster should, at a minimum have 12 physical files.
Not mirroring the redo logs, assuming multiple members, is not as critical.

ASM lost disk, rebuilt disk grp. No dbid, how to copy ctl file to ASM?

Hi all,
I'm trying to help out on what is turning out to be a real challenge.
This looks to be Oracle 10.1.0.4.0 (version showed by rman and sqlplus).
There is ASM...but it was set to redundancy of EXTERN, but not really external redundancy. This is a test box, and I guess they were just trying to use what disks they had....I dunno, it was set up long before I got here.
Out of all the instances I've had to look at....for this one server, I have no DBID's documented.
This is a HP-UX box....they replaced the bad ASM drive, and I rebuilt the DATADG disk group.
RMAN settings...well, show all just gives defaults, as that I don't have a control file in place. This was, however, set up to autobackup control files and spfiles...but I don't know the DBID, and can't figure how to find the DBID....
I did, however, find the snapshot controlfile...and hoping I could use that.
I am, however, stumped as to how to copy this copy of the control file, into ASM.
I have found and old pfile that I can use to start the instance. I have started it nomount with this.
I looked at the parameter for control file and found:
SQL> show parameter control_file
NAME TYPE VALUE
control_file_record_keep_time integer 7
control_files string +DATADG/instance/control01.ctl
, +DATADG/instance/control02.c
tl, +DATADG/instance/control03
.ctl, +DATADG/instance/control
04.ctl
So, I know where they are to go. This is such an old version, I guess there was no ASMCMD...I can't find that command.
I'm thinking, if I could find a way to copy this snapshot of the control file onto ASM in the old places it was, I could startup up the database, and it would then be able to restore and recover with the RMAN backups?
Any suggestions?
cayenne

Just a quick update on this.
I was able to find a snapshot of the controlfile on disk....
I went into asm and recreated the directory where the controlfiles were kept, and used rman to copy the snapshot controlfile to where the originals were kept:
export ORACLE_SID=+ASM
connect with sqlplus and do:
SQL> alter diskgroup DATADG add directory '+DATADG/instance';
Diskgroup altered.
Then in RMAN:
restore controlfile to '+DATADG/instance/control01.ctl' from '/u01/app/oracle/product/10.1.0/Db_1/dbs/snapcf_INSTANCE.f';
restore controlfile to '+DATADG/instance/control02.ctl' from '/u01/app/oracle/product/10.1.0/Db_1/dbs/snapcf_INSTANCE.f';
restore controlfile to '+DATADG/instance/control03.ctl' from '/u01/app/oracle/product/10.1.0/Db_1/dbs/snapcf_INSTANCE.f';
restore controlfile to '+DATADG/instance/control04.ctl' from '/u01/app/oracle/product/10.1.0/Db_1/dbs/snapcf_INSTANCE.f';
I then got out of RMAN...back into sqlplus and mounted the database instance:
SQL> connect / as sysdba
Connected.
SQL> alter database mount;
Database altered.
Checking to see backups:
RMAN> run {
2> allocate channel vh1 type sbt_tape;

How to mulitplex control files with raid

I have installed 8i DB server on a HP proliant server machine. Raid 2 is configured on the server machine with windows OS, two hard disks are mirrored.
It is often recommended to multiplex conrol files and redo log files on multiple hard disk to protect from disk failure.
how can i do this, as i have 3 logical drives but all they are of same physical device.
multiplexing control files on different logican drives is same as keeping them in the same default folder.
Please help making things clear ?????

1. RAID is all about availability and is not a substitute for duplexing of control files or online redo logs.
2. It is better to have multiple physical drive (sets) on which to place copies of the control file and online redo logs. That way, any failure of the RAID or file system will still leave you with copies of these vital files.
3. If you only have logical drives, it is best to place copies on various logical volumes. This way, you are (at least) protected from file system failure, corruption, or accidental delete.

How to Restore Control file to New Server

I want to test my backup by restoring the full backup of my production database on a separate test server.
I have taken following action for restore to test server:
•     Copy full backup to Test Server on same folder where it was in Production Server.
•     Copy parameter file to Test Server. (Edit control file location on it)
•     Connect Rman
•     Set DB with new DBID
•     Startup Nomount (from new parameter file)
RUN
ALLOCATE CHANNEL c1 TYPE DISK;
RESTORE CONTROLFILE FROM AUTOBACKUP;
ALTER DATABASE MOUNT;
Then we found following error:

How to relocate control file?

I want to relocate my control files to a new location.. I want to know my options on how to do this (apart from shutting down db). Users are logged on most of the time. Oracle version is 9i.

the only way i know is to shutdown the DB, change the parameter value CONTROL_FILES, copy the file to the new location and restart. Since this parameter cannot be modified online, i doubt you can do this without bouncing the instance.

Recover Datafile Using Old Control File in New Instance

The fact is there is no RMAN backup at all. Old database just dropped and uninstalled careless by my friend.
Fortunately there is still oradata folder(contain of control files and all datafiles).
But, I don't know to restore it manually and by system. I don't know file id of each datafile.
Helps / clues very appreciated.Well.If you have all control/online log/data files then there is no problem(also if you do not have pfile then create it manually according sample file).If your system is windows then create instance using oradim as
set ORACLE_SID=<SID>
oradim -new -sid <sid name> -intpwd <syspass> -pfile <pfile location>
sqlplus "/as sysdba"
startupif linux/unix then

the Oracle documentation , in one of its books points out....:
'Once the disk drive is repaired, the damaged control file can be restored using the intact copy of the control file from the other disk and the instance can be restarted'.
Is it achievable automatically.... or using some kind of sql commands and which , if any.....?????
Regards,
Simon

there's a parameter called
control_files
in your spfile/pfile whichever you use.
You can just multiply as many control files as you wish at OS level (copy) and list them in the parameter, then start your database.

hai,
for creating control file we proceed to ways:
1. create controle file using sql command as sys or system users
sql>alter database backup controlfile to trace;
system itself creates controlfile and keeps in udump directory.
2. using the old backup copies, edit the currect file locations, parameters manually.
Then run this script at nomount mode, to create the controlfile

How to write control file below data

Hi,
Here is my table
create table sample1 (name varchar2(5), num number(2));
sample.txt(Datafile)
vikram12
sharma13
sonu 14
Here is my control file
load data
infile 'C:\sample.txt'
into table sample1
fields terminated by "," optionally enclosed by '"'
( name char(5), num char(2) )
But it rejecting all the records. Just let me know where i went wrong.
Thanks in advance

fields terminated by "," optionally enclosed by
'"' As per your control file, the fields have to be seperated by commas but in your datafile it is seperated by space. Either change the delimiter in your control file or in your datafile
Using Comma Seperated file,
sample.txt(Datafile)
vikram,12
sharma,13
sonu, 14
load data
infile 'C:\sample.txt'
into table sample1
fields terminated by ","
optionally enclosed by '"'
( name char(5),
num char(2)
)Note:
1. You have to increase the length of name column as your datafile has values greater than 5 characters. First and second records will be rejected with NAME VARCHAR2(5)

SAP BW 7.0 - How to use control file?

Hello experts,
In my current project, I need to use a control file to load some flat files into BW.
In version 3.5 we had a option in the infopackage where we could select if it was a csv or a control file.
But in 7.0 version this option is not available anymore.
I found this threat: Use Control File to load data in BW7.0
But a .txt control file didn't work. Can somebody help me?
Thanks!!!

WS adapter can be used as Direct connection or Integrated Server Communication. Basically this adapter will be used to make communication between two SAP System's Webservice runtime. WS adapter supports Webservice reliable messaging , SAML and more security features. Using Direct connection you can communicate two SAP systems. In this case, you dont need any ESR objects and you just need to configure ID objects only.

How can I get file from multiple instance using file adapter

Hi.
Our system(PI7.1) have three application instances running with each physical servers.
We use sender file adapter.
The file data is sent to one of the servers.
Now, how can I get the file using three file adater?
Should I put the file "sapmnt(\usr\sap)" .
Or are there another solution?

Hi Ashutosh
You will have to use sapcar.zip which contains the utility Sapcar.exe utility for unzipping the files from SAP compressed files. (*.car file)
