Info on udump,bdump & cdump

hi, i know this is a really newbie question, but am just looking for further info in regards to what the above mentioned dumps are. a link or something would be appreciated greatly. thanks.

udump - user_dump_dest
bdump - background_dump_dest
cdump - core_dump_dest
udump:
whenever you trace a session, its trace file is written in this udump, session deadlock trace is written in this destination and if session sql causes an internal error ora-600, it trace also written in this destination.
bdump:
You will have your alert_DBNAME.log file here. You already know the importance of alert log file. Also, if oracle background process detects any error, its trace written here.
cdump:
core dump, you will have core directory in this destination for OS kind or fatal errors.

On oracleXE 10g installation, bdump, cdump, udump are not created

Hi all,
I installed Oracle XE 10g on my system successfully, but in
C:\oraclexe\app\oracle\admin
folder, bdump, cdump, and udump files are not created. Any help, what may be the reason will be appreciated.
Thanks in advance,

The SQL used to to create and configure a database excludes the ability to create the directories required. (unless using ASM)
This means that before running the dbcreate shell script (or equivalent), the directories need to be created via the o/s itself - usually a command line script.
The Oracle XE version for Linux combines this (the command line stuff and SQL stuff) into a single script in $ORACLE_HOME/bin/createdb.sh - I would expect that you will find a .cmd version of this for XE on Windows.
In this script, the mkdir command is used to create the required directories before the sqlplus is launched to create the database.
However, this script does not create separate bdump/adump/cdump/etc directories.
It creates the following 2 directories:
mkdir $logdir
mkdir $filedir
These are defined as:
filedir=$ORACLE_HOME/dbs
logdir=$ORACLE_HOME/log
Then it configures the init.ora for the db create as follows:
user_dump_dest=$logdir
background_dump_dest=$logdir
core_dump_dest=$logdir
audit_file_dest=$logdir
BTW, I suggest that you consider posting database questions in the [url http://forums.oracle.com/forums/forum.jspa?forumID=61]Database - General forum - this forum is specifically about the database SQL and PL/SQL languages. Not about db installation, configuration and so on.

Manner to delete the 'obsolete'(???) files in \udump , \bdump dir...

Hi ,
Is there any manner that OracleDB10g can delete automatically the 'obsolete' - maybe the files which were created 2 , 3 or greater number of days ago ...-files created in \udump , \bdump directories...????
In a way , for example , as the obsolete backups (of course if the Backup policy has been defined appropriately)....
Thank you.....
Sim

There is not an 'ideal' retention time, it all depends on your local politics. If you daily look for errors on the alert.log file, most of them refer to a trace file for further details, then you should investigate on that specific day and most probably you would end up raising a service request at metalink, depending on severity, you will then be requested to send the trace and log related files. If you wait 60 days to perform such task and if this issue was critical for the system, most probably you would not have any database to administer.
Those files are not historic archives, those files are meant to be reviewed ASAP. So a decision on whether to keep them for further analysis or purge them because they are informative only, should be done on a short time frame.

Help in moving bdump, udump and cdump

I have been asked to move the dump directories in a database. the path they point to is incorrect. how do I make this move so that they are located at a new path. OS is linux, database is 9i (9208)
thanks

I make this move so that they are located at a new
path. OS is linux, database is 9i (9208)
thanksI don't quite understand your requirement. Is the problem
1) The parameters don't point at valid directories? or
2) The directories are valid - but in the wrong place?
In both cases you will want to update the relevant initialisation parameters which are respectively
background_dump_dest
user_dump_dest
core_dump_destIn the second case you'll also likely want to move the os files - using the os mv command, but I'd rename the old alert.log file when moving it.

Hi, for Oracle 10g you can use the Oracle Policy for custom alerts, then you can monitoring the database from Oracle Database Control.

Problem in recovering database

I Have Oracle Database 10g (10.2.0.1.0) on Windows Server 2003
I have taken full hot RMAN backup of database.
I have copied the backup files from flash recovery area.
I have one other Machine having windows server 2003 And Oracle 10g Same version. I have copied the backup files from first machine to Flash Recovery Area folder on second machine.
Now i am trying to restore the database of first machine to second machine.
1. I have created a new instance on second machice with same name as in fiirst machine.
2. I have created one ORA password file as well.
3. SET ORACLE_SID=<name of DB as it was in first machine>
4. RMAN TARGET sys/<password given in newly ORA pwd file>@<DB name> nocatalog
5. SET DBID=<dbid of old database>
6. STARTUP NOMOUNT FORCE
7. RESTORE SPFILE TO PFILE '<path of new pfile>' from '<path where backup files are there>';
8. CREATE UDUMP,BDUMP,CDUMP,PFILE,ORADATA FOLDERS where required;
9. SHUTDOWN IMMEDIATE;
10. STARTUP NOMOUNT PFILE='<path of newly created pfile>';
11 RESTORE CONTROLFILE FROM '<path of backup files>';
12. ALTER DATABASE MOUNT;
Everything work fine till here
Now my next step was
13. RESTORE DATABASE;
Then it gives error like:-
RMAN> restore database;
Starting restore at 20-NOV-08

RMAN-06023: no backup or copy of datafile 1 found to restore
Firstly i copied backup files to flash recovery area, then i copied files to 'D:\oracle\product\10.2.0\db_1\database' as well. Because i have done it in 9i, in 9i i copied the backup files to this backup folder then while doing restore RMAN succesfully takes file from this folder & restores the database. but in 10g RMAN is not recognising the path of backup. How this problem can be solved? Or is this some different problem which i am not getting?
Waiting for reply..

Hi ORADBA,
Thanks for your response. Your solution worked. Actually there was a difference the Oracle installation on server from which i was taking backup is on E drive.
And the server on which i am trying to restore that database has Oracle installation files on D drive. That's why this confusion occurred.
But i have one query again. I am not able to recover my database fully.
Firstly i typed restore database command that worked. Thereafter i tried recover database command. that commant resulted in an error as given below. Than i typed command archive log list on SQL promt, from there i found the information of latest archive log. then i tried recover database until logseq 484 thread 1. That also didn't work. In the same situation i tried to open database i was able to open database using command alter database open resetlogs. I suppose i was not able to recover the database fully. Hi can i recover my database fully?
waiting for reply. Thanks in advance.

Process creation on solaris

Hi,
a few doubts on solaris process creation .
The "Jim Maurno" , Peeling back process layers , Part 1 , says that
man_nprocs( maximum number of processes system-wide) =
10 + 16*maxusers(number of megabytes of memory installed in the system)
Could someone tell me how these numbers 10 and 16 were arrived at ?

Before start creating a database manually, create all the necessary directories for log files/datafiles/ etc i.e. Udump, Bdump, Cdump, etc.,
3) startup mount pfile="path of the pfile"
Startup with NOMOUNT i.e startup nomount
4) run the create database script.
After creating the database, do not forget to run the two important scripts catalog.sql -- creates the views of data dictionary tables and the dynamic performance views
catproc.sql -- establishes the usage of PL/SQL functionality and creates many of the PL/SQL Oracle supplied packages
For more information on Manually Creating an Oracle Database, take a look at the Oracle Documentations.

They aren't. You may see references to trace files in the alert log pages .. for instance when you get an ORA-xxxxx alert it will show the name of the trace file that pertains to it.

Restoring RMAN backup on a different server

Hi oracle gurus
i have following scenario
i have a compressed backup set of a database
i want to restore that rman backup on to a different server.
both the server have same version of oracle.and both the server are of 32 bit.
please reply if any more info is required.

RESTORE AND RECOVERY PROCEDURE OF PRODUCTION DATABASE BACKUP ON TEST SERVERS
As part of disaster recovery exercise or to test the validity of a RMAN backup, a full restore and recovery of databases can be performed on scratch or test servers utilising the production RMAN backups which have been restored from the tape backups on these test or scratch servers.
This note will illustrate the above procedure by detailing the steps required to restore the backup of a production database (prod1) on a test server linux01 .
The following assumptions are made in this note:
The RMAN backups have been restored from tape backups to the same backup location on the test server as the production server where the backup was originally taken
The identical directory structure as is present on production has been created on the test server. This will apply to not only the location of the database files (data, control files, redo log files), but also to the bdump,cdump, udump and adump locations.
Controlfile autobackup has been enabled. This is important.
Overview
Restore the spfile from the autobackup
Restore the controlfile from the autobackup
Restore the data files
Recover by applying archived redo log files
Open the database with resetlogs
Restore the SPFILE
[oracle@linux01 prod1]$ rman target /
connected to target database (not started)
RMAN> set dbid=4266928631
executing command: SET DBID
RMAN> startup force nomount;
startup failed: ORA-01078: failure in processing system parameters

starting Oracle instance without parameter file for retrival of spfile
Oracle instance started

RMAN> run
2> {SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u02/backup/prod1/%F';
3> restore spfile from autobackup;
4> }
RMAN> shutdown immediate;
Restore the Control File
In this case, the instance is now being started with the restored spfile. We can create a pfile as well from this spfile is so required.
RMAN> startup nomount
connected to target database (not started)
Oracle instance started
RMAN> set dbid=4266928631
executing command: SET DBID
RMAN> run
2> {SET CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u02/backup/prod1/%F';
3> restore controlfile from autobackup;
4> }
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
Restore the database
RMAN> restore database;
Recover the database
The recovery will fail at a point where it cannot restore any more archived redo log files.
In this case the last archived log file which has been backed up is sequence 613.
This information can be obtained by issuing a LIST BACKUP OF ARCHIVELOG ALL command.
So RMAN will fail when it tries to apply sequence 614 ….
RMAN> recover database
[oracle@linux01 PROD1]$ rman target /
connected to target database: PROD1 (DBID=4266928631, not open)
RMAN> sql 'alter database open resetlogs';
RMAN>

Hi Guys
I need to know where Oracle writes logs for Fail Safe components, Fail Safe Manager and Fail Safe server?
Any idea?

I have a basic knowlede of Oracle, but this is something I need help with:
I have a Windows cluster with Oracle Fail Safe. There will be multiple databases on this cluster. Oracle and Oracle Fail Safe are installed on disk D: on both nodes (local disk).
When Fail Safe creates a sample database it creates this directory structure on cluster disk O:
OFSDB
OFS1
admin
OFS1
adump
bdump
cdump
pfile
udump
flash_recovery_area
OFS1
ONLINELOG
oradata
OFS1
{code}
All database related files like parameter files are created on the cluster disk, not in Oracle Home, where they are by default.Hi
most of the directories that you refer to are controlled by initialisation parameters in the parameter file for the database. What would probably be sensible for you to do is to use DBCA not to create the database, but to create the scripts to create the database. You can then edit those scripts appropriately.
In particular the directories used in your example are controlled by these parameters
adump                           audit_file_dest
bdump                           background_dump_dest
udump                           user_dump_dest
cdump                           core_dump_dest
flash_recovery_area         db_recovery_file_dest (and db_recovery_file_dest_size)the online log directory tree will be created if you choose to use oracle managed files for the redo logs, alternatively you can manually specify them in the create database statement.
The generated scripts should contain a .bat file which precreates the admin structures.
so to recap, use dbca to create the scripts :- edit the scripts, don't set ORACLE_BASE.

How to upgrade DB

What are the methods/considerations to upgrade DB?

If you want to upgrade from 9 to 10 I have a method and a file.
I have a file, it is written in Spanish, may be you want it.
If you want, I can send it?
Do you have an e-mail address so that I can send it?

I am adding the text, but it is in Spanish my mother tongue.
1.- Instale el software de 10g.
2.-Corra la utilería pre-upgrade:
     SQL> @?/rdbms/admin/utlu102i.sql en el home de la versión y usuario anterior.
3.- Hacer los ajustes. Los init spfile orapw lk copiarlos a 10g con oracle10 en el init cambiar las rutas de los bdump cdump udump create pfile debajo de $ORACLE_HOME/admin/dbname
Hacer los ajustes del init o spfile para que apunten a los dump destinies de 10g.
4.- Shutdown la base de datos a ser actualizada.
Cambiar con –R el owner de oracle9 a oracle10 de los archivos de toda la base
5.-Switchear al nuevo home Oracle Database 10g y hacer una inicialización de la base:
          SQL> startup upgrade;
     En esta misma sesión crear el tablespace siguiente:
6.-Crear el tablespace SYSAUX.
6.1.- Se muestran distintos tamaños para esta creación dependiendo de las características del sistema:
Factor     Small     Medium     Large
Number of CPUs     2     8     32
Number of concurrently active sessions     5     20     100
Number of user objects (tables and indexes)     500     5,000     50,000
Estimated SYSAUX size at steady state with default config     500 MB     2 GB     5 GB
7.- Correr el script de upgrade:
SQL> @?/rdbms/admin/catupgrd.sql
8.- correr la utilería de status post upgrade
     SQL> @?/rdbms/admin/utlu102s.sql
9.-Recompilar cualquier código PL/SQL y Java.
     SQL>shutdown immediate;
     SQL> startup
     SQL> @?/rdbms/admin/utlrp.sql
10.- Borrar los init, spfile, orapw, lk de la dbname en $ORACLE_HOME9 y debajo de admin. Borrar la carpeta dbname con sus subcarpetas
11.- El listener y tnsnames de $ORACLE_HOME10 debe estar actualizado para tomar los servicios de la bd que se le hizo el upgrade.
12.- Se crea la dbconsole como sigue:
emca –config dbcontrol db –repos create
14.- Levantar el isqlplus de $ORACLE_HOME/bin/isqlplusctl start

Oracle 9i problems in amd processor

Hai,
I have installed oracle in my system but it occupying the whole disk space. it is showing low disk space.my system configuration is amd processor,512 mb ram,
asus mother board.please any of them solve my problem.
Thanking you
sudhakar.

I have installed oracle in my system What kind of system?
but it occupying the whole disk space
it is showing low disk spaceWhat about archivelog?
Or maybe you have just 3GB disk... don't know, because you didn't provide important info.
my system configuration is amd processor,512 mb ram
asus mother board.What is the purpose of this characteristic (where is the point)? I guess this has nothing to do with disk space occupation.
So if your problem is low disk space, then try:
1. check whether your database is running in archivelog mode and whether is generate archive redo logs. If your database need to be in archivelog mode (preffered for production db) then backup your archive logs and then remove it from disk.
To check whether your database is running in archivelog mode execute from sqlplus (as sys or system):
select log_mode from v$database;To check whether (of course this is a must in archivelog mode) and where is your database generate archive logs execute from sqlplus:
show parameters log_archive_start
show parameters log_archive_dest2. check sizes of bdump, cdump and udump directory and delete unecessary trace files, or coredumps. (oc course there might be large alert log file)
To show location of bdump, cdump and udump directories execute fro sqlplus:
show parameters dump_destPlease, be more specific and write important information in your future posts.

Steps to be kept in mind while creating a database

Hi Friends,
I have written the very basic steps that are required for creation of database. The steps are as following:-
1.     Create the Environment /Folders. “bdump”, “cdump”, “udump”, “pfile”, “redo”, “control”, “datafile”. These are folders that have to be created in “d:\oracle\admin\orash\
2.Create the Pfile.
Open the notepad write the blew parameters and Save in the pfile folder with the name ‘initorash.ora’
db_name=orash
Instance_name=orash
Background_dump_dest=’d:\oracle\admin\orash\bdump’
core_dump_dest=’d:\oracle\admin\orash\cdump’
user_dump_dest=’d:\oracle\admin\orash\udump’
Control_files=’d:\oracle\admin\orash\control\control01.ctl’, ‘d:\ oracle\admin\orash\control\control02.ctl’
undo_management=auto
undo_tablespace=undotbs1
remote_login_passwordfile=exclusive
compatible=9.2.0.0.0
3.     c:\>oradim –new –sid orash –startmode m –pfile d:\oracle\admin\orash\pfile\initorash.ora
4.     c:\>orapwd file=d:\oracle\ora92\database\pwdorash.ora password=orash entries=5
5.     Creation of Database: -
Open the notepad write the blew parameter & Save this file in pfile folder with the name of ‘createdb.sql’:-
          create database orash
logfile
group 1(‘d:\oracle\admin\orash\redo\redo01.log’) size 200m,
group 2(‘d:\oracle\admin\orash\redo\redo02.log’) size 200m
datafile ‘d:\oracle\admin\orash\datafile\system01.dbf’ size 300m
6.     C:\> set oracle_sid=orash
7.     C:\>sqlplus/nolog
8.     SQL> conn sys as sysdba
9.     SQL>startup nomount pfile=’d:\oracle\admin\orash\pfile\initorash.ora’
10.     SQL>@d:\oracle\admin\orash\pfile\createdb.sql
11.     SQL>@?\rdbms\admin\catalog.sql
12.     SQl>@?\rdbms\admin\catproc.sql
Thanks,
Shiv Kumar Dadhwal

since you choose to use auto undo management, you'd better add undo tablespace into that create database statement.
Plus, carefully choose a Character set that suit your need. Some time it's hard to change it after database go live.

Manual database creation

Hi all,
I need to create a small database manually.
What are the mandatory fields for DB creation.
What are the steps to be followed?
If anyone have the script please send me.
Thanks in advance.
regards,
prem

hi prem..
you have to create script for database creation..
no problem if ur on 9i.
let do below step..
step 1. open ur dbca and create script for ur database.
step 2. create folder
bdump, udump, cdump ---- d:\oracle\ora90\admin\3 folder 1.bdump, 2. udump, 3.cdump
folder name some ur db_name -----d:\oracle\oradata\"folder name must be some ur db_name"
step 3. go cmd prompt
start>run>command [enter]
cmd>set oracle_sid=dbname
cmd> create password file..... ( see mentioned link in previous post)
cmd>create and start services ( see mentioned link in prev. post)
cmd>sqlplus/nolog
sql>conn sys as sysdba
connected
sql> run all database creation scripts.
script generate in
d:\oracle\admin\script\>>>>>>.scritps
Note.>> Drive may be C:,D: whatever according ur setting.
hope this helps
