Multiple database Instance on single server

Hi friends,
I want to install Solution manager in the same system which I have installed ECC6. So I want to install another database(10g). Can any one tell me the possibities to install it.
regards,
Nageshwar

Hi Nageshwar,
yes, it is possible.
See chapter "Multiple Oracle Homes" of the guide "SAP ERP 2005 SR2 ABAP on Windows: Oracle" available on <a href="http://service.sap.com/instguides">http://service.sap.com/instguides</a>
You can also install one more DB in your already existing ORACLE_HOME.
best regards

Multiple Database Instances on Single Server and effect of NLS_LANG

What is the effect of the NLS_LANG registry setting on a Windows server that is to host multiple database instance each created with a different database character set ? The server needs to support data in the following languages : Thai, Chinese Traditional, Chinese Simplified, Vietnamese and Korean. Selecting the Unicode character set(AL32UTF8) is not an option since the application is not Unicode complaint.
My understanding is that as long as NLS_LANG is set correctly on the client connecting to the particular database instance then the data will be stored correctly - is this correct ?
What should NLS_LANG be set to on the server if there are multiple oracle instances with different character sets ?

My question is not in relation to connecting to the database on the server itself but with regards to client connections. What I need to know is what is the effect of the NLS_LANG setting in the registry on a server that has multiple databases each created with a different character set ?
Say for instance, the server has two databases - one created with the character set ZHS16GBK and the other created with the character set JA16SJIS and NLS_LANG is set to SIMPLIFIED CHINESE_CHINA.ZHS16GBK in the registry on the server. Will Japanese data that is inserted into the database that has character set JA16SJIS be stored correctly when it is inserted from a client with NLS_LANG set to JAPANESE_JAPAN.JA16SJIS even though NLS_LANG is set to SIMPLIFIED CHINESE_CHINA.ZHS16GBK on the server ?

Multiple database instance on one server

Hi experts
We are planning to implement ERP, BI, Solman, CRM and MDSD on windows/oracle platform. There is an idea about system landscape that all database instance of production systems are installed on one server and central instances of each system are installed on separate servers. Is there any performance or maintenance risk about this scenario? What is the advanteges and disadvantages of this landscape? Shall we prefer central system installation?
I'm waiting for your recommandation.
Best Regards...

Hi,
From experience one disadvantage in having an Oracle farm, is if the server plays up
or needs a reboot you of course lose all the systems databases.
Also getting all customers to aggree a maintenance slot together can be a pain.
Failover needs to be considered, DR also.
IMHO separate servers, but that is my preference I'm sure there are advantages.

Multiple SAP instance on single server.

Hello Experts.
We are in process of implementaing SAP solution withLandscpe having systems ECC 6.0, SolMan 4.0, BI. We are planning to have 3 Sytem landscape for all.
Now but currently we are having only one Physical server
Is it possible to Install 6 SAP system on single server?(DEV and QAS for ECC, Solman, BI respectively). The server is having sufficient hardware for 6 system as per sap standered. Planne OS is RHEL and DB MaxDB. Initially we are having 16 GB RAM extendable.
Will SAP support such kind of landscape?

Hello,
We did not put 6 systems on the same server but we are running fine with 4 systems (R/3, XI, BI) on one server (8 itanium, 32 GB ram).
16 GB seems very small for 6 systems...
Don't forget that beside the obvioous economy, they are also big cons with mutualization.
When the server crashes because of a hardware failure, all of your landscape is out and the phone rings a lot.
When you need a reboot for one system, you have to stop all the others...
Good luck !

Olivier

Need to get data from multiple database instances in a single query

Hi,
I need a small favour from you guys. The prob is as follows:
I need to get name, row_id from table A from schema 1 and gbu_name, name from table B from schema 2 where a.name = b.name. I wrote the query in the following manner:
SELECT a.name, a.row_id, b.gbu_name
FROM Schema1.A as a, Schema2.B as b
Where a.name = b.name
But this query is not working and the error is like " The table does not exists".
Please update me how to avoid the error and get the right sort of result.
Thanks & Regards,
Debabrata

Ah, youre actually asking different things.
In your topic title, you say youre running separate instances
In your body text, you say you are under different user/schema
So tell me, do you have more than one database or not? How many entries in your TNS file?
I would say, for "multiple database instances"
SELECT
a.id, b.id
FROM
tableA a
INNER JOIN
tableB@OTHER_DATABASE_LINK_NAME b <--NOTE!
USING(id)And of course you will have to look up CREATE PUBLIC DATABASE LINK sql..

Can there be multiple ASM instances on single node?

Hi,
Can there be multiple ASM instances on single node?
This one says No : http://www.freelists.org/archives/oracle-l/02-2008/msg00317.html
And This one says Yes : http://www.databasejournal.com/features/oracle/article.php/3571371
Thanks in advance.
Thanks,
Harsha

...that document doesnt say you cannot have multiple ASM instances on a node. It says "...ASM, +you only need one ASM+ instance for that computer, to manage the two database instances that use ASM."
The fact that you only need one - and I cannot think of a good reason to have more than one - does not preclude the fact that you do seem to be able to have multiple ASM instances on a single node, each looking after its own set of disks and diskgroups.
Again - I cannot think of a good reason to do so though!

Multiple databases in a single query

I need to query multiple databases in a single query.
e.g.
Database d1 contains table t1 with column id
Database d2 contains table t2 with column id
I need a query like
SELECT * FROM t1, t2 WHERE t1.id = t2.id;
is this possible in jdbc? if yes can anyone help with some sample code?
thanks,
Ashish Saraf

It is not possible using the JDBC API to query tables in two or more databases using a single query. The reason is that a JDBC Connection is made to a single data source.
However, some databases support the idea of federations or linked tables. What you do is inside the database manager link or federate a table that is present in another DBMS. Then, pose a single JDBC query to the one DBMS which will have its own table and links to the external tables.
Another approach is to use a special JDBC driver with a built-in integration engine that will perform a query across multiple databases. In effect, the system poses separate queries to the different databases and integrates and joins the data together for you automatically on the client-side. That is much easier than doing it yourself in code, but that is also possible for simple queries.
As part of my research program, we have released a shareware version of the UnityJDBC driver that can query multiple databases using a single SQL query. For more information, see:

How to add multiple databases for a single frontend

We have a project based on distributed databases and we have to workout on .Net framework.I want to know some information of connecting multiple databases for a single frontend and how can we access them.
If so we have connected 2 databases for a single frontend in future if I want add one more database to it how it will be possible to do it without disturbing the current connectivity.
Please help me in resolving this problem.
Thanks......

hi,
what do you mean by connecting 2 databases? can you explain further?
using entityframework you can connect to different databases
public class CustomerContext : DbContext
public ReportContext()
: base("DefaultConnection")
public DbSet<Customers> Customers { get; set; }
and your connectionstring (config file)
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=D:\\Database\Project.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
you can add more connection strings on it.

Multiple instances on single server

Hi all,
I have a Solaris 10 server with 2x dual core CPU's.
I am wondering if it was at all possible to install Business Intelligence Server on this single OS twice? And if it is, can I split the CPU between the different instances?
The reason for this is that I would like both production and test/development installed onto the same OS to cut costs. But I don't want the test/development instance to use resources that would affect the performance of the production environment.
Ideally I'd like the 2 instances, with the production instance using 3 cores, and the test/development instance using 1 core. If the RAM could also be split that'd be great.
Thanks for your help in advance.
Cheers

Yes, you can have multiple instances of Presentation Services (PS) ([see my blog posting for details|http://rnm1978.wordpress.com/2009/08/25/multiple-rpds-on-one-server-part-1-the-bi-server/]) which would let you split envs, but you'd do that with a single instance of BI server. I don't know if it's possible to run multiple BI servers
I don't think you should be trying to do this anyway, several reasons why not:
1) It's not supported to run multiple PS on one server. That should be reason enough not to do this on prod.
2) If it's not possible to run multiple BI Servers on one server then you'd end up running one BI Server with dev/test/prod RPDs - you'd never be able to bounce your BI Server for dev work without taking down prod
3) Any time you needed downtime for dev, you'd affect prod
4) Any patching you wanted to do on dev might affect prod
5) Any experimental work you do that crashes dev would affect prod.
If you only have the one box available to you for costs reasons then you should be looking into virtualisation of some kind, eg http://www.virtualbox.org

How to access multiple database present in single instance

Hi Team,
In oracle 11.2, can there be multiple databases in an instance??? In one of our environment, I could see multiple databases in an instance. Could you please help me in giving the data dictionary or query to access those databases?
Actually, querying v$database, I could see only one database which is same as instance name. But in inventory, there are multiple database in an instance?
I am still not exactly clear about this. Can someone help me with this?
Thanks!
Vidhya

In Oracle one instance manages one (1) database. A database consists of multiple *schemas*.
Other vendors erroneously call a schema 'database'.
So, no, you didn't see multiple databases.
There is also one datadictionary, consisting of a set of views.
All views beginning with dba_ list the entire database, all schemas.
All views beginning with all_ list the objects you have access to.
All views beginning with user_ list your own objects.
The view DICT show you the contents of the datadictionary.
Oracle also has online documentation at http://docs.oracle.com
From your question it is clear you should read the document called the 'Oracle Concepts Manual'.
You can find all documentation for 11gR2 here Oracle Database Online Documentation 11g Release 2 (11.2)
Too many people here don't make any effort to read it. This is probably the reason why you got no response.

Multiple AIA instances on same server?

Hi,
Does anyone know how to install multiple AIA instances on the same SOA server? The installer hints that this might be possible, although I have not seen how this is done because the installer expects an empty oracle home path. The only information I have found so far is for an earlier 2.x release of AIA and that suggested:
"Each SOA installation must be in his own ORACLE_HOME directory.
Each AIA installation must be in his own ORACLE_HOME directory.
You must point to different databases. You can not have mulitple SOA schema's in one sinlge database."
Is this true?
Thanks,
Kev.

Hi Laxman,
If its a testing purpose its ok to have a one oracle_home and single listener for multiple DB. One problem when applying oracle patches for one of the instances running in a multiple DB running then you need to bring all the DB running in that host since the oracle_home is sharing between all db instances.
Thanks
Sunil Rajesh K.C.Starting with 11g, patchset updates are full installs and done into a new home. This makes it possible to migrate one instance at a time. However, your point would be a consideration for one-off patches like CPUs.
However, please note ... OP --- PLEASE NOTE even with multiple oracle homes, you still only need a single listener.

Multiple databases in one single RAC cluster

Hi, I would like to know if one can have multiple databases running on a single RAC cluster, we have several databases in our shop and would like to consolidate all of them into a single 3-4 node RAC cluster running databases with 10.2 and 11.1 versions.
I am newbie to RAC and would like to get some clarification if anyone has done this, google search comes up with few hits on this topic, so obviously this is not doable.
In our case we have one database supporting critical applications and few other not so critical but are used very extensively between 9-5, so what is the use of RAC if I cannot consolidate all my databases into one cluster, or if I need a separate cluster for each of these critical databases?
I have been all the Oracle docs that keep repeating one database multiple instances and one instance-one machine-one node, they don't even advise running multiple instances on a single node?.
I appreciate any insight.
Thanks.

ora-sql-dba wrote:
Can you give more details on how you would setup multiple databases running different versions on a single RAC cluster, I am yet to find any documentation that supports or even elaborates on this topic.You can configure a cluster with 12 nodes. Then, using dbca, configure a dev instance for nodes 1 and 2, a prod1 instance for nodes 3 to 6 and a prod2 instance for nodes 7 to 12.
You also can configure each of these instances for all 12 nodes. And use it on all 12 nodes.
Or, after configuring it for all 12 nodes, you can start the dev instance on nodes 1 and 2, prod1 on 3 - 6 and prod2 on the remaining nodes. If dev needs more power, you can for example shutdown prod2 on node 12 and start another dev instance there.
My issue is with the 2nd option - running more than one instance on the same node or server. Why? Each instance has a basic resource footprint ito shared memory needed, system processes required (like db writer, log writer, sys monitor) etc. It does not make sense to pay for that same footprint more than once on a server. Each time you do, you need to reduce the amount of resources that can be used by each instance.
So instead of using (for example) 60% of that server's memory as the SGA for a single instance, if you use 2 instances on that server you now have to reduce the SGA of each to 30% of system memory. Effectively crippling those instances by 50% - they will now have smaller buffer caches, require more physical I/O and be more limited in what they can do.
So unless you have very sound technical reasons for running more than one instance on a server (RAC or non-RAC), do not.

Oracle multiple homes on a single server

This is about maintaining multiple oracle homes within a single server for different oracle versions.
On a Solaris-9 server I need to have 2 11g versions where 11.1.0.6 serves one instance and 11.1.0.7 is expected to serve 2 upgraded database instances.
For multiple homes involving full installations it is simply a matter of installing software in a new home with a new home-name. But 11.1.0.7 is a patch installation that needs an existing 11.1.0.6.
What is the recommended approach in this case to host multiple oracle homes?
Oracle's documentation claims their cloning tools can be used (prepare.pl and clone.pl perl scripts).
It also has something on runInstaller -clone mention.
What I've achieved so far is:
(1) Install 11.1.0.6 via Solaris-packaging onto a clean server. This installed onto $ORACLE_BASE/product/11.1.0 using ORACLE_HOME_NAME=OraDb11g_home1
(2) Upgrade this to 11.1.0.7
(3) Detach this oracle-home from global inventory
(4) Rename the folder 11.1.0 to 11.1.0.7
(5) Re-attach as new oracle-home (name=OraDb11g_11_1_0_7) and relink at the same time using runInstaller -clone command
I am no DBA, so I'd like to know if the above approach is good enough or if there is any other recommended approach.
Many thanks.
G.Sharma.
Edited by: Sharmag on May 31, 2012 11:38 AM

@Helios, thanks but curious - why is this not stuiable under installation? - regards,
@Shrini - I am using Solaris packaging for installing oracle software. So unless I rename the target folder I cannot achieve different the same 11.1.0.6 in 2 different folders.
Even if I managed to tweak Solaris packaging and install the second oracle (11.1.0.6) into a second folder, wouldn't that be the same as renaming an oracle folder-name? In this case, we still would end up with the same issue of relinking and correcting the global inventory.

Multiple Domains in a Single Server

Hi:
I have a requirement where two domains (at this time) need to be set-up in single server.
Each domain need to have a Admin Server , OSB, SOA, OSR and OER as managed servers and each runs in different port.
Each domain has it own schema, but shares the same instance and database
Is it possible to run both domain at same time, (i-e) i should be having both the servers up and running and should be able to open the consoles of Admin server and managed servers for each of the domains configured?
Regards,
RK

Is it possible to run both domain at same time, (i-e) i should be having both the servers up and running and should be able to open the consoles of Admin server and managed servers for each of the domains configured?That should be no problem... Use different port numbers, different schemas and different domain directories... You can share the same product installation...

Multiple database versions in a server

Hi all,
to day i have seen the file cat /etc/oratab like
db1:/u01/app/oracle/product/8.x.x.x/db_1:Y
db2:/u01/app/oracle/product/9.x.x.x/db_1:N
db3:/u01/app/oracle/product/10.x.x.x/db_1:Y
db4:/u01/app/oracle/product/8.x.x.x/db_1:N
here my doubts is how we can install multiple oracle versions in a single server. a server will be having only one version of operating system. suppose like if we assume our os is linux 4.7 we can install only 10g and 11g. but how we can install 8i and 9i database versions.
how all these oracle versions are going to be install in a single server.
please clear my doubts.
thanks a lot...!

thanks a lot...!Each lives in its own ORACLE_HOME. If, as it seems from your comments, you have no problem with the concept of the 10g and 11g both on the same server, why should the addition of 8.x and 9.x be any different?
