Trace file and control files !!

hi,
I have created trace file of the control files by using 'alter database backup controlfile to trace' command. i have two questions..where can i find this trace file and how can i use this trace file to generate the control files.
Waiting for the replies...
Regards,
Saad Bin Khalid

1. You can fine the trace in the udump folder ... you can check the file time stamp to check when you created the file as it may be possible that here are other user trace files too
$ sqlplus / as sysdba
SQL> alter database backup controlfile to trace;
Database altered.
SQL> show parameter USER_DUMP_DEST
NAME TYPE VALUE
user_dump_dest string /PROD/udump
SQL> exit
$ cd /PROD/udump
$ mv PROD_ora_30823.trc cr_ctl.sql
$ vi cr_ctl.sql
edit the control file script
Now you have a new control file script to re-create your control file.
2. You can edit the same and execute at nomount stage to generate new controlfiles ... remember controlfiles should be removed before creating the new ones

Load data with SQL Loader link field between CSV file and Control File

Hi all,
in a SQL Loader control file, how do you specify link with field in CSV file and Control file?
E.g. if I wat to import the record in table TEST (col1, col2, col3) with data in csv file BUT in different position. How to do this?
FILE CSV (with variable position):
test1;prova;pippo;Ferrari;
xx;yy;hello;by;
In the table TEST i want that col1 = 'prova' (xx),
col2 = 'Ferrari' (yy)
col3 = default N
the others data in CSV file are ignored.
so:
load data
infile 'TEST.CSV'
into table TEST
fields terminated by ';'
col1 ?????,
col2 ?????,
col3 CONSTANT "N"
Thanks,
Attilio

With '?' mark i mean " How i can link this COL1 with column in csv file ? "

Flat File and Control Files Questions

Greetings,
I've worked with Oracle for about 10 years, but have little experience with using sql-loader.
I have data from Visual FoxPro tables going into Oracle 10g via a Perl script. I am having issues and therefore have a couple questions.
1) If the data from my foxpro table is basically everything in the table as in 'Select * from table-name', does the control file have to list every column that is in the FoxPro table?
-- I have a case where a FoxPro table has 15 columns but we are trying to upload only 10 columns. The script is dynamic. It selects * from each FoxPro table and creates a Flat File for each on the fly. Then sql-loader uploads the data to Oracle. The Flat File for this one table has data from all 15 columns, but the Control File only lists 10 of the columns to be uploaded into Oracle.
2) Do the column names in the control file 'have' to match both the column names in the FoxPro table and the Oracle table, or only the Oracle table?

Yes - use the FILLER spec to ignore columns you do not care about - http://download.oracle.com/docs/cd/B19306_01/server.102/b14215/ldr_field_list.htm#sthref946

Database creation having a trace of the control file

Hi,
I want to move a database from one server let's say A to another server let's say B I have a copy of all the datafiles, redo logs, control files and init file of the database fron the server A. I have a trace of the control file.
I copied all these files on the server B in the location /dispecer_date/oradata, except init which is in ORACLE_HOME/dbs
I thought that the simplest method to recreate the database is from the backup of the control file writing in sql the command CREATE CONTROLFILE how is written in trace and replacing the word REUSE with the word SET in CREATE CONTROLFILE instruction.
I obtained an error:
ORA-01503: Create controlfile failed
ORA-01160: file is not a data file
ORA-01110: datafile: '/dispecer_date/oradata/system.dbf'
Why? The db_block_size parameter is 4096.
Thank you,
Mihaela

Here are the steps .....
sql > shutdown immediate ;
create identical dir structure on server b
copy all datafile,controlfile,redologfiles and pfile to target server ,And put them in same dir as of source.
now on taget server
sql > startup mountpfile = path of the pfile
sql > alter database opn
or
sql > alter database open resetlogs ;
this will do the trick, I don;t think recreating the controlfile is a good option hare , becuse you likly to loose some data if you stick on that one.

How to create parameter and control file like filename + date

Hello there
I am trying to create parameter and control file with following command
in SQLPLUS
create pfile='/u03/oradata/WEBDB/backup/initWEBDB.ora' from spfile;
In RMAN
copy current controlfile to '/u03/oradata/WEBDB/backup/cf_longterm.cpy';
how can I put date at the end of filename like
initWEBDB8jan06.ora and cf_longterm8jan06.cpy
Thanks in advance

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.

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

Using archivelog and control file from other Oracle server

I am still bothered with my backup process.
I have 2 AIX boxes (same model, say A and B); both have BAAN 5 and Oracle 10g R2 on. Right now my colleague insists to use the export pump (cold backup) from Prod Oracle server (A) to restore the Oracle server on Box B. The Prod server has the archivelog mode turn on. But it will miss any transaction data from import pump till the crash point of Box A. So this is my confusion.
Can I pass the control files and archivelog files form Box A (prod server) to Box B and use them to restore the Box B as the latest Prod server? How?
I tried to convince them to use the RMAN backup? But not successful?
I think the best way is probably to use the Oracle Data guard. However, there is always one concern to my manager and colleague, that such process will cause the data on the restored server (failover, Box B) not recognizable by the BAAN, which define the objects (tables).
Thanks

Performing a logical backup is not useful to restore to the point of failure. The only valid and available option is a hot backup/archivelog mode. Your recovery manager backup perform a controlfile and redologfile backup, so those can be restored at the destination. You must take care of the way you perform the backup, and ensure the paths where your backup is being deposited are visible by the second node. A shared storage with same mount points is suitable in this case. A tape robot configured at both nodes is also a suitable solution.
Recovery manager perfoms a controlfile and spfile restore, too. This rman command perform the action:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';
I don't see any problem on the recovery manager side, and technically speaking, on the Oracle side it is perfectly possible to restore your database at a remote location. I don't know what happens on the BAAN side, if you are required to have it configured to be operative on the target node. You could try to clone your database at the node B, configure BAAN and prepare the proceduere in case of failure.
Configuring a dataguard is also a recomended action. So it is to think about Cold Failed Over clusters. I have recently performed a CFC configuration with BAAN. No problem it works smoothly.

Location of Redo log and control files?

Dear all,
I am checking the location of redo log and control files, but found that the redo log file (like log02a.dbf ....) in the same directory of data files. However, I couldn't find any control files in the data files directries.
What could be the location of control files?

Oracle binary and control files

Hi All,
I want know whether the oracle binary and control files are they related in anyway.
I have my physical files on a SAN storage and my oracle binary files on a local disk.
In case if I delete my oracle binaries and restore it from a backup, will I be able to start my database without any issues.
Since all my oracle datafiles,controlfiles and redofiles are located in SAN storage.

Oracle binaries and control files are related in some way because Oracle version is recorded in control files:
oerr ora 201
00201, 00000, "control file version %s incompatible with ORACLE version %s"
// *Cause: The control file was created by incompatible software.
// *Action: Either restart with a compatible software release or use
// CREATE CONTROLFILE to create a new control file that is
// compatible with this release.When restoring Oracle binaries on UNIX you should take care about setuid bits on oracle executable to avoid local connection issues by non oracle Unix accounts.

SQL Loader and control file changes for different users

In the front end of my application I can select a data file and a control file, and load data to the table mentioned in .ctl file. Every user who logs in uses the same .ctl file and so loads onto the same table. Now I want the user to load data onto the table in his own schema. I can get the username of the user currently logged in and i want to insert it into that username.table. So can i copy the contents of the .ctl file into a variable, modify it into username.table in that string and pass that variable as a parameter to the sqlldr command instead of the .ctl file.
Or is there a better way how I can modify the same control file everytime to change tablename to username.tablename in .ctl file and pass to sqlldr to load data to table in local user schema table.
Thanks and Regards

Thanks for the reply .. user do have their user credentials but only for the application ... but all users use a common loader and control file once they log into the application. So irrespective of which user is logged in he selects the same control file and loads to the same table mentioned in the control file .. i instead want user to be able to load to the table in control file but into his schema like username.tablename instead of just the tablename mentioned in .ctl file.

Multiplexing redo logs and control files to a separate diskgroup

General question this one...
I've been using ASM for a few years now and have always installed a new system with 3 diskgroups
+DATA - for datafiles, control files, redo logs
+FRA - for achive logs, flash recovery. RMAN backup
Those I guess are the standards, but I've always created an extra (very small) diskgroup, called +ONLINE where I keep multiplexed copies of the redo logs and control files.
My reasoning behind this is that if there are any issues with the +DATA diskgroup, the redo logs and control files can still be accessed.
In the olden days (all those 5 years ago!), on local storage, this was important, but is it still important now? With all the striping and mirroring going on (both at ASM and RAID level), am I just being overtly paranoid? Does this additional +ONLINE diskgroup actually hamper performance? (with dual write overheads that are not necessary)
Thoughts?

Some of the decision will probably depend on your specific environment's data activity, volume, and throughput.
Something to remember is that redo logs are sequential write, which benefit from a lower RAID overhead (RAID-10, 2 writes per IOP vs RAID-5, 4 writes per IOP). RAID-10 is often not cost-effective for the data portion of a database. If your database is OLTP with a high volume of random reads/writes, you're potentially hurting redo throughput by creating contention on the disks sharing data and redo. Again, that depends entirely on what you're seeing in terms of wait events. A low volume database would probably not experience any noticeable degraded performance.
In my environment, I have RAID-5 and RAID-10 available, and since the RAID-10 requirement from a capacity perspective for redo is very low, it makes sense to create 2 diskgroups for online redo, separate from DATA, and separate from each other. This way, we don't need to be concerned with DATA transactions impacting REDO performance, and vice versa, and we still maintain redo redundancy.
In my opinion, you can't be too paranoid. :)
Good luck!

In trace file and output file showing bind variable instead of value

Hi,
database 9i
optimizer = choose(for cost based)
In my trace file and output file showing bind variable instead of value.
in my trace file 20 queries.
I alse set this parameter in session level.
alter session set events '10046 trace name context forever, level 4';
but still showing traceoutput file bind variable.
Pls help its very urgent

Can you post the query for which the bind variable values are not being shown and the trace output for the same?
Probably it is listed down somewhere when you actually executed the query among the others. Try completely analyzing your trace file..

Database restore without temp, undo and control files.

Hi All,
You might found this question silly but I don't know so asking this question here.
I have cold back up of the database. Now, I want create clone of that database, but I have some different paths for the DBFs so I will create new control file after restoring the database.
Now, I know that I don't need control files and tempfiles to be restored. I have 10 undo files in backup but on the new clone database I don't need all 10. I want only 5. So can I do the restoration without undo , temp and control file and later on add undo and temp?? and if yes then tell me that can I add them at mount level??
This is my first restore, Please guide me its very urgent

Therefore, we do a RECOVER with a CANCEL to simulate an Incomplete Recovery.Completely agree with you Hemant. And the links you've provided,i've gone through many times. Excellent description.
I just wanted to know in above(OP's) scenario if he has complete cold backup(includes online redo logs), does he really need open reset logs or any recovery?
Regards!no , if you have cold backup with online redo log files then i don't think so you need to open database in resetlogs.Resetlog is always after incomplete recovery or recovery using backup controlfile or you dont have redo logs.
I am completely agree with you that with given scenario for the cold backup undo tablespace would not be part of recovery and you can
-offline drop undo tablespace file
-create another one undo tablespace and its undo datafile
-point spfile to that newly undo tablespace
I think Aman is saying in the context of restore and recover online database where undo tablespace create a vital role in database recovery, the undo blocks roll back the effects of uncommitted transactions previously applied by the rolling forward phase.

Very high log file sequential read and control file sequential read waits?

I have a 10.2.0.4 database and have 5 streams capture processes running to replicate data to another database. However I am seeing very high
log file sequential read and control file sequential read by the capture procesess. This is causing slowness in the database as the databass is wasting so much time on these wait events. From AWR report
Elapsed: 20.12 (mins)
DB Time: 67.04 (mins)
and From top 5 wait events
Event Waits Time(s) Avg Wait(ms) % Total Call Time Wait Class
CPU time 1,712 42.6
log file sequential read 99,909 683 7 17.0 System I/O
log file sync 49,702 426 9 10.6 Commit
control file sequential read262,625 384 1 9.6 System I/O
db file sequential read 41,528 378 9 9.4 User I/O
Oracle support hasn't been of much help, other than wasting my 10 days and telling me to try this and try that.
Do you have streams running in your environment, are you experiencing this wait. Have you done anything to resolve these waits..
Thanks

Welcome to the forums.
There is insufficient information in what you have posted to know that your analysis of the situation is correct or anything about your Streams environment.
We don't know what you are replicating. Not size, not volume, not type of capture, not rules, etc.
We don't know the distance over which it is being replicated ... 10 ft. or 10 light years.
We don't have any AWR or ASH data to look at.
etc. etc. etc. If this is what you provided Oracle Support it is no wonder they were unable to help you.
To diagnose this problem, if one exists, requires someone on-site or with a very substantial body of data which you have not provided. The first step is to fill in the answers to all of the obvious first level questions. Then we will likely come back with a second level of questioning.
But when you do ... do not post here. Your questions are not "Database General" they are specific to Streams and there is a Streams forum specifically for them.
Thank you.
