Disadvantage in 2 seperate Instances in seperate database in same CPU

Hi,
kindly tell me the disadvantages in having 2 separate Database Instances in two different oracle database in same CPU box. As i think, it will severely effect the Virtual Memory of the system, and increase the responsibility of Administrator to Administer the System.

You can run two database's on one machine but the server should have sufficient virtual memory. Also the memory should be properly distributed to both the instances, allocating the remaining to o/s processes. If you have dual cpu server than its again a great thing. OR if your hardware does not support than it will be nightware running two database's on single machine.

Querying Tables from seperate Databases

I'm sure this is very simple, but I cannot figure out how to query information from two tables that live in two seperate databases.
Ex.
Select database1.table1.field1, database1.table1.field2, database2.table1.field1
from database1 left outer join database2 on database1.table1.field1 = database2.table1.field1
Any help would be appreciated!

If you are using "database" in the Oracle sense, rather than in the sense that other databases use the term (i.e. a SQL Server "database" is analogous to an Oracle schema), you would need a database link.
In database 1
CREATE [PUBLIC] DATABASE LINK dblink_name
CONNECT TO username
IDENTIFIED BY password
USING tns_aliasThen
SELECT tab1.field1, tab2.fieldN
FROM table1 tab1 LEFT OUTER JOIN table2@dblink_name tab2 ON (tab1.field1 = tab2.field1)Justin

Can i create more than one instance for single database?

HI
anybody can tell me how to create more than one instance for single database(without using RAC)?
thanks
Kalanidhi

Anandji,
I sometimes think differently. I also think like what this person is asking..(although I have installed and administering 5 different RAC databases)
The main doubt of mine is that we create multiple instances accessing the same storage area.
Anyway the controlfiles of all instances will have the same information except the instance_names and instance id's.
Hence I always think , why can't it be possible to to create another instance in the same system and point it to a controlfile which is copied from the other instance.
Why can't the same files be shared between the two instances in a same system ?
I know I am thinking a little bit confusing...
Anyway I need to test that also...

Can I able to install many instances in one database. If yes please let me

Hi,
Can I able to install many instances in one database. If yes please let me how to do in Oracle 10g and *9i*.
Thanks,
Senthilnathan.

Can you clarify what you trying to accomplish please? An instance consists of the memory structures, while a database consists of the memory structures and data files. Hence a RAC is a single database, with a instance per node (since each node will have the memory structures but all nodes access the same, single database).
If you are referring to multiple schemas or applications inside the same database then yes, that is perfectly fine and done generally.

Create dev and test instances of Apex on the same server and database

I have a dev and prod instances of Apex on different servers. I want a test instance on the same server as the dev instance.
I am using workspace export/import so all instance workspaces have the same workspace id. The application ID is the same on each instance, in the same workspace. This allows pages to be exported/imported in the differenct instances.
My question is (I am sure it is obvious) can I have more than one instances of Apex on the same database (dev and test) and have each instance have identical Workspace IDs, etc.
Sam

Hi Sam,
But you can have more than one database on the same server.
What we do is create a separate database for each APEX versions we are supporting (we still have a customer using APEX 2.0).
All the databases are accessed with the same APACHE config. All you have to do is change the DAD and have a separate dad for each database (i.e. each APEX versions).
ex : /pls/apex_dev /pls/apex_test
This way , I can run different APEX versions on the same server.

Create multiple instance in a database

is it possible to create multiple instance in a database.if possible then is it possible to activate many instance at a time.(in personal edition)

Instance in Oracle refers to the Oracle database "engine" - a collection of processes using a shared memory area, accessing a physical Oracle database.
Multiple instances are possible on the same platform for different physical databases. But not a Good Idea..
Multiple instances on different platforms are for the same physical database using Oracle Real Application Clusters, aka Oracle RAC.
Thus your question does not make a lot of sense. My guess is that you are in fact refering to an Oracle session instead as this is "in the database" as you refered to.
Each client that connect to Oracle, creates/establishes an Oracle session. A single client uses one (usually the default) or more sessions (usually used by a multi-threading client).
By default, the Oracle Instance supports multiple Oracle (client) sessions. Including Personal Oracle. In the past, Personal Oracle limited (via the Listener) the number of remote clients (i.e. clients on other platforms) that can connect. I would assume that this is still the case. I however do not recall that there were a limit imposed on the number of local sessions that could be created - the limiting factor here is afterall the power and resources available by the PC. It's very unlikely that a common PC will be able to support a Personal Edition Oracle instance and 100's of local client sessions at the same time.
If you do mean instance as per the strict Oracle definition - why would you want to create two Oracle instances (each with its own physical database) on a PC? That does not make sense on a large db server platform. It makes even less sense on a small PC platform.
Each Oracle instance has overheads (processing and memory). Each physical Oracle database has overheads (system space, temp space, redo, logs, etc). Why duplicate these overheads?
On a single platform - what can two Oracle instances (less capable because of reduced resources availability) do what a single Oracle instance cannot do faster and better and more effectively? Thus is it not a Good Idea to run multiple instances on a single platform. (exceptions acknowledged)

How to Synchronize Test Instance with Production database on regular basis.

Hello
How to Synchronize Test Instance with Production database on regular basis.
I want to update my Test Instance with Production ERP on daily basis without downTime.?

Hi,
I recomend to configure physical standby database for your production and when ever you requir open standby Using a Physical Standby DB in Read Write Mode and Flashback DB, so that you can revert all the changes back and put the db in sync. Please follow below metalink notes.

Instance recover vs Database recover

Hi,
I want know what is the difference between Instance recover and Database recover, if someone have documentation about it.
Thanks :)

Do you know difference of instance and database?
Instance = Background processes + SGA
If you shutdown your database with "shutdown abort" command or killing smon process you need to instance recovery on startup. ın this situation when you start your database the SMON background process performs instance recovery using online redo log files.
Database recovery is differ from instance recovery.
Database Restoring involves restoring backup files from backup storage to disk. This can be done to replace damaged files or to copy/move a database to a new location.
Database Recovery is the process of applying incremental backup, archive redo logs and online redo logs to the database to roll it forward. One can roll-forward until a specific point-in-time or roll-forward until the last transaction recorded in the log files.
Hope this helps

Difference between Instance Crash and Database Crash in Standalone and RAC?

I am new to Oracle Environment. I would appreiciate if i get clarified on the "_+Difference between Instance Crash and Database Crash in Standalone and
RAC_".+
Oracle Version: 11.1.0.7.0
O.S Version: HP-UX B.11.31 U

Sivaprasad S wrote:

Literally, database crash means that the database itself is damaged in some way. A disk is no more. Data files are corrupted. Etc. The database itself thus causes the crash - and a database crash will also cause all database instances (RAC or single) for that database to crash too.
An instance crash will therefore mean that the crash occurs in the instance due to an Oracle bug or similar. In other words a s/w error and not a database error. The database is still "fine", but the instance not. Instance crashes. However, any other instance on that same (RAC) database will still be fine as the database itself is unaffected by that s/w error in the crashed instance.
If you mean something different, please enlighten us. Not all crashes are equal. {noformat};-){noformat}

Creation of Standby database on same host

Hi All,
I am using oracle 9.2.0.1.0 on windows XP machine.
*I want to create the standby database for my primary database on same machine.
But both tha data base is heaving diff instance as well as the diff database name say "ASHU" for primary & "TEST" for standby database.
I took the backup of all datafile and copied it in the standby location.
Generate the standby control file also and copied to the standby location.
But when i am going to start the standby database it is giving the below error:

You do not change the dbname of the physical standby database. They always must have the same name as the primary.
Here is a snippet from my standby initialization file for a 9i installation. Notice the parameter LOCK_NAME_SPACE that was replaced in 10g with DB_UNIQUE_NAME

Thanks, Your help and guide will appreciated very much.

Hello,
The directory for the creation of the logfiles does not exist, from the error:
RMAN-06136: ORACLE error from auxiliary database: ORA-00344: unable to re-create online log '/db/app/oracle/product/9.2.0.5/dbs/ /db
/redolog.001/catalog1/catalog1_log1.rdo'
ORA-27040: skgfrcre: create error, unable to create file
HP-UX Error: 2: No such file or directoryI.e., there is no such directory as *'/db/app/oracle/product/9.2.0.5/dbs/ /db/redolog.001/catalog1/catalog1_log1.rdo'*
Your db_recovery_file_dest parameter may be set here, therefore change this:
'/db/redolog.001/catalog1/catalog1_log1.rdo' size 5m,
' /db/redolog.003/catalog1/catalog1_log2.rdo' size 5m,
' /db/redolog.002/catalog1/catalog1_log3.rdo' size 5m;To this:
'catalog1_log1.rdo' size 5m,
'catalog1_log2.rdo' size 5m,
'catalog1_log3.rdo' size 5m;And try again.

Two database in same machine

Hai
I want to create two database in same machine. I searched in google but no use.
Is it possible in oracle 9i r2?
If so,Anybody please help on that.

Why do you want to duplicate database overheads? Why two sets of system and process monitoring processes? Log writers? Database writers? Etc.
Why two SGAs? Why two system tablespaces? Two temp tablespaces, undo tablespaces? Two sets of redo logs? Etc.
You now have two database footprints. Instead of a single large SGA with properly sized buffer cache, shared pool, large pool and so on - you know have two smaller SGAs and smaller caches and pools that are now less capable and less scalable.
Why would you want to do this?
There are no sound technical reasons for running multiple database instances on a server - unless it is something like a 32 CPU/multicore server with 256 GBs of memory. But then why not use this as a cloud-type server on which you can run multiple server VMs? One VM for each database, as that provides more flexibility than multiple databases on a single server(physical or VM)?
In today's world of cluster and cloud computing, running 2 databases instances on the same server does not make much sense. And needs to be backed up by reason and logic that justify such an approach.
