Multiple oracle instances in single SLD

Hi
There is requirement from management that they need a seperate database in the present SLD (DEV,QAS,PRD). Since they plan to move this database in future to another SLD. I have gone through some SAP notes that u can have multiple SAP systems and underlying databases on a single host. Also I noted that u need to have a seperate transport directory.
My doubt is since SAP SID requires a Database SID during the installation. So how this new database can be incorporated in the present system.
If any white papers,pitfalls are highly appreciated.
Thanks

Hi Erick
It is the same oracle version i.e 9i rel.2. we need a seperate oracle insance. My concern is even though u installed a new database making it available in the present DEV,QAS,PRD is a problem. How the existing Dialog instances will recognise this new oracle instance.
what i came to know from the documents is that u need to have a seperate SAP systems and underlying the new database is quite possible and u need to take care of sizing. I searched on the net but couldn't find a similar scenario.
Any other inputs are higly appreciated.
Thanks

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,

...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 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 Oracle Instances

Hi
Can u people help me in installation of multiple oracle instances in windows nt. I am using oracle 8i with NT. I like to start multiple oracle instances . How can I do it and how can i use svrmgrl with different instances.
please help me

Hi,
(On unix)
If you have installed for example two instnces ( IDs : ORCL1, ORCL2), you must do
this to start ORCL1 or ORCL2:
--- ORCL1
export ORACLE_SID=ORCL1
svrmgrl
startup
I hope it works on NT
Bye.
---so for ORCL2

Multiple ASM Instances on single node

Hi All,
After going through some threads it seems to me that multiple ASM instances on a node is not supported and recommended by ORACLE but i coudn't find any ORACLE document or support matrix mentioning this. Can any one give me a pointer to this. Please correct me if i am wrong and Multiple ASM instances are fully supported by ORACLE.
Thanks,

Multiple ASM instances on a single node are supported but not recommended due to several issues you could encounter during that kind of configuration.
Possible interraction between those instances for identification of each disk area usage,each disk area permissions , database instance to asm instance mapping and so on, could result in unwanted behaviour, as ASM is in some way just oracle's representation of LVM.
Intention is that any kind of distinction/separation of oracle related data under the ASM should be done through the disk groups.
So it seems it would be better to apply this kind of logic rather than doing suspiciously magical and rare configurations that could bring you similiary strange and unexpected problems.

Multiple Oracle Products on Single Server

Can we install Multiple Oracle Products for Development and Testing on a Single Server?
Oracle Database 9i Enterprise Edition.
Oracle 9i Application Server
Oracle Applications 11i (Financials GL,HRMS PAYROLL)
Oracle Discoverer 4.x
Oracle Internet Developer Suite (Forms Server, Reports Server,
If yes,
Do they need to be in separate ORACLE_HOME or same ?
Also what should be the sequence of Install, i.e. what should be installed first?

The following products needs to be in their own Oracle Home:
Oracle Database 9i Enterprise Edition. --> in its own O_H
Oracle 9i Application Server --> in its own O_H (assuming this is 1.0.2.2 or 9.0.2)
Oracle Applications 11i (Financials GL,HRMS PAYROLL) --> in its own O_H
Oracle Discoverer 4.x --> in its own O_H (this is a 806 based product btw)
Oracle Internet Developer Suite (Forms Server, Reports Server) --> This can either be in its own O_H or in the O_H which has 1.0.2.2 Oracle9i Application Server.

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.

Multiple BI instances on single BI Server

Hello,
I want to know if we can have multiple instances of BI run on single installation
i.e on single installation
I would like to run two different rpds and two different webcatalogs.
Can this be done?
If this can be done does oracle support this kind of installation?
Regards,
Deep

Hi,
Technically, I think you can run two mutually exclusive services on one server. You need an web application layer for managing like OC4J, weblogic, etc wherein you deploy two instance of presentation services with different port and each of these have DSN to different RPD's. I doubt you will be able to run on an IIS server (web layer).
As far with the support, I think oracle supports single instance of Presentation services, but check with your oracle sales person on that.

Multiple Oracle databases on Single host

Hi Gurus,
I am new to SAP World. We are planning to install multiple SAP systems (ECC/BW/SRM/XI) on a single host with Oracle 11.2.0.2. As per SAP instguide, the Oracle RDBMS software should be owned by ora<SID>:dba. So we are planning to install the oracle software for the first dev system ERD under 'oraerd:dba' id. And the next will be under 'orabwd:dba' and the third under 'orasrd:dba'.
My questions is, instead of having multiple ORACLE_HOME's owned by individual id's, can I have one consolidated Oracle_Home owned by 'oracle:dba' which then controls all the oracle db's and its datafiles.
I know there is a SAP Note to do this for Oracle RAC (prd is being planned this way), but can we do the same for Single instance also.
Best Regards
Shiv

Hi Orkun,

The reason we were looking to out all under 'oracle' was that our DR site for the prod is going to be single instance physical standby using DG. SAP recommends to have the OS user on the DR host to be oracle, so that there are no issues with permissios for log shipping.

Hi Shiv,
Technically, there's no restriction to configure your system, by this way. But from SAP point of view; at the first step, because the the installation is not completed as referred by SAP installation guide, you will not able to get support by SAP. For the instance, if you face with a problem during the productive, SAP may not support your installation.
Secondly, you may face with the problems at the database upgrades and applying patches. For example, you need to stop all the databases when you decided to patch one of them.
I can count many restrictions about this issue. As a summary, from technical way, it is possible to have one Oracle home, but it is strongly recommended to have different Oracle home folders for each Oracle installation.

Orkun Gedik

Timesten Database caching multiple oracle instances

Hi All,
I need to cache two oracle users which are running on different IP. Can Timesten support this ?
How do i cache another datastore , if one user is already cache in timesten .

This means One timesten can cache one single oracle database. ?
CJ>>    Correct. One TimesTen database can cache data from one Oracle database. Note that a TimesTen instance (installation) supports multiple TimesTen databases.
Is there any other way to shrink permsize ?
CJ>>    There is no other way to shrink PermSize. And you can only shrink it if the currently configured size is larger than you really need.
How can i deploy timesten on RAC?
CJ>>   The same way as you would for a single instance database. A RAC database is just a single database. TimesTen fully supports RAC.
Is there any similar feature available like RAC ?
CJ>>   TimesTen provides 'Cache Grid' where you can have multiple TimesTen caches which are caching the same Oracle database work together to act as a single distributed cache.

Multiple Oracle Instance

i am having 2 seperate Oracle 10g database servers,one is window based,second is AIX based (unix based), Can any one tell me, how can i create 2 instance for a database in unix and 2 instance for a database in windows.
what will be the command or options and recommendation/pre-request for both installation.
Regards,
M. Aamir

Hi
If you are referring databases as instances then you can simply use the GUI to create as many databases as you like. You can invoke it through command prompt by typing DBCA or you can go to
Start->Programs->Oracle-home->Config&MigTools->Database Configuration Assitant.
If you want seperate "instances" then you need to create seperate initxx.ora files with required parameters for memory etc.
If, however, you require High Availability then you should read doc on RAC. It requires shared storage (SAN or NAS) etc. You can have multiple instances for same database.
Hope it helps.

Multiple ASM instances using single cluster install - Is it possible??

Hi,
I have 2 node RAC cluster installed on Linux. All the storage is on EMC. I need to setup another environment using HP storage on the same hosts. Is it possible to created second ASM instance using the same cluster install?? I wanted to have clear separation b/w EMC and HP environments and that's wondering if it's feasible to do that.
Haven't tried it yet to see if it complains.
Thx
Anitha

Anitha,
The data migration won't happen (at least not aggressively) until you do step 2 in your list where you remove the EMC disks. That removal operation will take a long time as Oracle will have to move the data before it can complete the operation. If you want to be sure, I'd recommend creating a new disk group with one of your new disks, put a small tablespace in it, create some data in it, then add a disk to that new group and remove the original disk. Then you'll have some confidence in the procedure and verify that it works without risking your production data. After you test, you can drop the disk group and use the disks for their intended purposes.
To answer your question, yes, that's the process exactly as I suggested it above. Should work fine--but will probably take a while to do the remove, so be prepared to leave that running for quite a while (i.e. don't expect to close the terminal and go home right after running the remove).

Utility for handling multiple Oracle instances (docs, changes, etc.)

Please, remove this topic if it's not appropriate for this forum.
I handle several databases (up to 50), and I would like to have some utility for handling them in way to have:
- graphical GUI for their physical location
- to keep info about all changes that I make on those instances
- keep info about various properties (DB version, log_mode, last backup, etc, etc...)
is there such utility (maybe even not from Oracle)
tnx

haven't find a useful one, so I'm closing it

Multiple oracle database on single server

Hi,
In our organization, we are going to install, SRM, BW and XI on a single server, each going to use its own database.
So, in that case, will the listener and listener port for all the three database will be the same, or we need to define it during the installation.
Please help me in this regard.
Thanks and Regards,
Sailesh K

Hi Sailesh,
The best option is different binaries (Oracle & Sap), different Filesystems and different ports (Listener, msserver, gw, and so on) for every system you install. And, of course, different system numbers!

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
