I have an update Oracle database 11g installed on ZFS Storage, and I need to make cloning for it. HCC feature is enabled.
How can I make this?
Using RMAN backup + ZFS Snapshot + ZFS Cloning ?
I cannot start ASM on my Oracle Database Appliance.

When using oakcli to create an oracle home in ODA, are there any parameters or configuration files to determine the directory to install the database software? I want to create 3 separate 11.2.0.3 ORACLE_HOMEs in these directories, all owned by the 'oracle' user..
/u01/app/db1/product/11.2.0.3/dbhome_1
/u01/app/db2/product/11.2.0.3/dbhome_1
/u01/app/db3/product/11.2.0.3/dbhome_1
But oakcli seems to accept only the version parameter:
oakcli create dbhome -h
Usage:
oakcli create dbhome [-version <version>]
where:
version - Version information for creating the database home.
That would install Oracle 11.2.0.3 into /u01/app/oracle/product/11.2.0.3/dbhome_1 only. The reason for the separate homes is for flexibility to patch them independently of each other (ie dependent on only the requirements of the products they support)
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
View 11 Replies View Relatedi 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 ?

I am new in oracle I have installed Oracle in work group, while i work group it is working fine. But latter I have change the server from work group to domain. At that time Oracle was not working , not able to connect.
After that I change the Domain to work group again. And same problem exist. But I found that lsnrctl is working fine. But OracleServiceXXX is not able to startup in services.msc

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?
Yesterday i installed oracle 11g r2 by default i installed database Oracle with the installation .but today i tried to create the database with the name green tat also completed successfully..the problem is in startup

database mounted
select instance_name from v$instance; But it SHowing the instance name as Oracle...i tried with the other method also
export oracle_sid=green
sqlplus /nolog

database mounted
select instance_name from V$parameter;
and it shows instance name as green..i tried to see the datafile location for green database
select file_name from dba_data_files; it shows the orcl datafile locations.

what could be issues & how to resolve this problem? do we need to reinstall client software again not available this DLL file after searching on oralce home directory .
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
I need the step by step procedure for the cloning of database in linux environment .

My organisation is currently discussing different storage options for the database storage. Our production database is nearly 2TB and we do not want to continue with the existing NetApp storage (we use a 2 node RAC running 11.2.02 with nfs filesystem from NetApp filer).
We were looking at different options and came across Nimble Storage, they are very fast growing company aiming mid-range storage customers. The initial talks and demonstration looked very promising in terms of IO performance (they claim 40,000 - 60,000 IOPs for their CS400 series Nimble Storage array) and other options they are providing but we understand that majority of their customers are using it for VDI and other infrastructures.
They have demonstrated us using if for Oracle database with ASM storage over iSCSI LUNs. We are yet to do the POCs and benchmarking.
Has anyone come across Nimble Storage for running Oracle databases?
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

DB: Oracle 10g R2
OS: SUSE Linux SP 1 x864
We are maintaining a DR of our Database Server(oracle 10g R2 atop SUSE SP1 Linux) using Platespin(
[URL]......
Platespin is set to replicate(block based), incremental data(delta) every 1.5 hour from Production to DR site over a 30 Mbps dedicated fiber link.
Our maximum changes of data per day(during business hours) wont exceed 300 MB. During business hours Platespin replicates at least 1 GB at every replication cycle, while during off hours it replicates 300 to 500 MB per replication cycle. We are facing this strange issue with this box only(SLES 10 SP1 + Oracle 10g R2), we have protected MS Exchange 2007 Server based workloads without this strange issue, i.e in case of Exchange only delta replicates from Production server to DR site on Platespin.
Platespin support says us that Oracle re-indexes its database for better performance, so it is possible that re-indexing causes the blocks level changes on the storage, and since Platespin works on Block level, thats why it replicates so much(even though data is not changed that much)
here is actual words of Platespin support
<snip>
I think whenever Oracle database Indexing happens, it changes almost most of the Blocks of database and Platespin replicate all those Blocks.
As you know, Platespin checks the Date/Time attribute of every blocks before replication and if Date/Time attribute changes from last replication, it considers as changed block and replicate those blocks on Platespin Appliance. So, my suggestion is just look into the Oracle server behaviour before/after Data indexing process and do needful or do some workaround to overcome this issue.

is there anything we can do at oracle level ?
I am having an issue with the LOBs in our Database. Our production DB is about 71G right now - if i do export/import using the DataPump - I see the data volume becomes 40G. I am sure its because of the LOBs in my Database. Our application uses lots of LOB datatype and I think the space is not being released.
The challenge is I cant do a full export/import in my Production DB as its a 24/7 system and to do export/import I need min. 5 hrs - which my business will not permit. I can I claim the unused space here. I have used Segment Advisor - but it has only given me 6G of space gain.
Is there any script I can try to use to reclaim space in the database.
I have a question about Oracle schemas. Oracle schema is the user with its datase objects (table, index, eg) .In two different Oracle schemas, there can be two tables with same names. When the users connect to same Oracle instance they can access these tables with schema.tablename convention.
However, how is that structure handled in physical database storage. Are there two tables created with same name physically? I mean are these two tables with same name stored in different database files?
I need to find out in DB Package where this Package is installed (in which schema). The problem is this DB Package can be installed in various schemas. This means that I can't use select user from dual or system environment SYS_CONTEXT('USERENV', 'OS_USER').
What I would need is something like $$PLSQL_UNIT

I am using 10.2.0.1 on OEL5. I have installed CRS, Oracle home, ASM on both nodes and everything is fine.
When invoked dbca to create a database, it says:
*'DBCA could not startup the ASM instance configured on this node. To proceed with database creation using ASM you need the ASM instance to be up and running. Do you want to recreate the ASM instance on this node?'*
Is it a bug? because some blogs say this is a bug. And patch 8288940 will solve this. They also say this patch is to solve the incompatibility between 11g ASM incompatibility with 10g. But here I am using everything of 10.2.0.1.
Db : 11.2.0.3
Os :Aix
We have 3 database under an ASM on same machine.Each db has 2 disk group's.

Db Name :DT7

How these database instance correctly identify the disk group? Can we use two database instance for One disk group?
