i have production database (1102.0.3.0) in Windows 2008 server R2 64 bit version . My database has some schemas which has partition tables and Db links and M views also .
Now my team lead asked me to setup the same environment(As cloning ) in testing environment also ... I have lots of options to create the same setup database using options like export/Import , data pump , hot backup and cold backup, Rman .
My doubt is which option will be best and optimal to achieve the same ?which approach i should proceed ?
Oracle Database 11g 11.2.0.1 SE1 I have a production database server which is currently having about 1TB of data.I need to shift this server to a different location with minimum possible downtime. Which is the best option this?RMAN backup, or datapump export and import
I am trying to perform cold cloning at my home pc. when i am trying to create control file , i got this error.
SQL> CREATE CONTROLFILE SET DATABASE "fclone" RESETLOGS FORCE LOGGING NOARCHIVEL OG 2 MAXLOGFILES 5 3 MAXLOGMEMBERS 5 4 MAXDATAFILES 10 [code].......
ERROR at line 1: ORA-01503: CREATE CONTROLFILE failed ORA-01163: SIZE clause indicates 12800 (blocks), but should match header 74112 ORA-01110: data file 2: 'C:appIndraoradatafclonesysaux01.dbf'
i have started cloning the database thru RMAN on my personal machine .the problem now is the database which i tried to clone and the database for which i was doing this task both are not working.I tried changing the database name and log file name using the parameters
db_file_name_convert= log_file_name_convert=
the main database files are on disk1 and the clone database files are on disk2...i have restored the controlfile by command
>alter database recover using backup controlfile ; after some time its giving cannot alter and giving message that system datafile needs recovery even i tried > alter database recover automatic not worked then i used the command
>> alter database recover using backup controlife until cancel;it gave message saying change generated so i cancelled the recovery and tried to open the database using RESETLOGS even now its giving the message SYSTEM file needs media recovery
i have a task to do do a sanity backup just to check the backup is recoverable or not , but i failed to install the agent in my server due to we have a HP DATA Protector for a backup and my manager told me i need to take the backup from HDP not as i always do take the backup on disk and then move this backup on test server and do a task cloning ,i do the cloning by rman but the backup on tape drive , i mean by rman open a channel to take the backup from PROD to TEST?
As I understand we can't clone database across platform using Rman, as Rman backup taken on say Unix is useless to be recovered on Windows. Though I think of Export and Import, will copying the datafiles, logfiles, controlfile will serve purpose for cloning across platform?
Note that I do not mean Transportable tablespace here. Only copying cold backup across platform
Our db is growing pretty fast and now we need to purge / archive some of the data to another schema, we'll only keep 6 months of data in the current schema/table.
Here is the scenario:
2 schema: scott (source) & scott_arc (target)
tables in scott (source): emp (regular table - criteria is date) emp_p (partitioned table - criteria is date)
Task: we have to purge/move/archive old data (only 6 months will stay in source, rest will move to target/arc) from these two tables and create identical same tables in SCOTT_ARC and move data to *_arc schema, need to create indexes too, similar to source.
- for regular tables, we can do select/insert, on date basis - for partitioned tables, we can try exchange partition, as the current partitions are some like these:
EMP_20090104 <YYYYMMDD>
and this is not consistent too, means we don't have partitions for all the days in a month, this is the current status is:
MCDH_200909 2 (for 09 have only 2 days of data, means 2 partitions) MCDH_200910 4 (for Oct have 4 days or data or 4 partitions) MCDH_200911 16 and so on ... ...
Need patch strategy specially for production environment?? We have production environment and we are planning to patch our databases using PSU pacthes with no downtime. Our production environment has standby. We have one option that we can make standby to primary. Is there any other options that we can use?
I am trying to clone a database on another server with different direcory structure. So that path on the source db server are /u04 whereas on on target db server it would be /u03.
Since this I am testing it on small database initially I have kept all datafiles, backup and archivelogs at /u04 and /u03 on the source and target db servers respectively Now I have copied the backups from source db server to target and since path is changed, I cataloged it
However during restore I am getting
Quote:ORA-19870: error reading backup
Here are the session details
RMAN> catalog start with '/u03/oradata/db7fra'; searching for all files that match the pattern /u03/oradata/db7fra List of Files Unknown to the Database ===================================== File Name: /u03/oradata/db7fra/DB7/archivelog/2011_03_15/o1_mf_1_16_6qyvpb3w_.arc File Name: /u03/oradata/db7fra/DB7/backupset/2011_03_15/o1_mf_annnn_TAG20110315T123018_6qypyv5v_.bkp

I have altered permissions on the backup files as well but of no use

We have production database.We would like to have 15 last online full backups (sheduled once a day) and to be possible to restore database to a point in time only between last backup and current time.
If I configure retention window for 15 days, archive redo logs in last 15 days are also backed up, and this consumes lot of space, which is a problem here (database files and arhive logs are of a huge size).(There is enough space for 15 full backups and archive log for one day though)
How to configure RMAN for this?I was thinking about configuring retention policy for 15 days and adding this lines at the and of a daily RMAN cronjob:
backup archivelog all not backed up; CROSSCHECK BACKUP DEVICE TYPE DISK; DELETE NOPROMPT ARCHIVELOG ALL;
We are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.
We have done cloning of our ORACLE APPLICATION(11i),after that performance of ERP is getting slow (like fetching of data). What we can do to increase the performance.
I have a database(10.2.0.5.0) in solaris 10 , i simply take a tar backup of ORACLE_HOME andextracted them into another server (which is solaris 10 only) and linked the binaries after that when i connecting with sqlplus.
I am getting following error
SQL*Plus: Release 10.2.0.5.0 - Production on Fri Oct 4 14:49:48 2013 Copyright (c) 1982, 2010, Oracle. All Rights Reserved. Enter user-name: /as sysdbald.so.1: oracle: fatal: libskgxp10.so: open failed: No such file or directoryERROR:ORA-12547: TNS:lost contact
I would like to tell that i have also oracle 11gr2 running on the server my oracle_base is same for both(10g 11g)but ORACLE_HOME is different.
New to oracle FAQ. I'm interested in oracle, waiting to explore more Technic's in 10g with a proper guidance. Hope i'm in the right place.Here is my question.
I need steps for configuring rman cloning with catalog & without catalog.were in prod db the source is in /u01 & in auxiliary db the client want in /u05. how to do it. here i have recreate control file or not
oracle 11g ASM RAC under OEL 5.6 . i just want to do a cloning so first i create cloning of my oracle home and then i create pfile and i get this error
SQL> startup nomount; ORA-29702: error occurred in Cluster Group Service operation SQL> exiti google it , i found this issue is with relink RAC binaries due to the souce database is RAC and destination is not
[oracle@backuptest ~]$ cd $ORACLE_HOME/rdbms/lib [oracle@backuptest lib]$ make -f ins_rdbms.mk rac_off bash: make: command not found
While cloning using RMAN DUPLICATE command, one can convert all files from various locations to new locations by using DB_FILE_NAME_CONVERT. One can also retain the same locations with no conversion by using NOFILENAMECHECK. My question is what if I want to convert some, and not convert others?

I am new to Oracle, like to get clarified on below;
Our product uses Oracle11gR1 and in new release we are going to use Oracle11gR2. For this we are performing following steps:
(1) Install Oracle11gR2 on a machine where our product (Oracle11gR1) is already installed. (2)Upgrade Oracle11gR1 schema to Oracle11gR2. (3)For using upgraded schema in our product installer we create clone of upgraded schema. (4)For creating clone we are using Oracle11gR2 DBCA utility. (5) Clone files are successfully created (DBC, CTL, DBF).
Now we performed same steps from another machine and DBF file size changed very much. On one machine it was 89 MB and on second machine it was 150 MB. There is no different in schema and both machines are Windows 7 machines.
Tor educe size of schema we tried different space reclamation commands but size is not changing.
