RAC enabled database binaries vs non-RAC enabled binaries

We have a 5 node cluster in which we will be installing Oracle database binaries onto and creating Oracle databases on, some of which will be standalone and most of which will be RAC enabled.
Is there a difference in 10g RDBMS binaries that are "cluster enabled" versus a single node 10g binary install? Can non-RAC enabled databases use the same set of RAC enabled database binaries? I don't want to install two Oracle home's....
Hopefully that question makes sense. Thanks in advance for your input.

Well, this is a RAC database on AIX so not sure whether checking only libknlopt.a is enough on AIX.
I did not good answer from Oracle support also regarding same question.
I know, if I have RAC DB Binary installed and want to convert to Non RAC, you compile with rac_off option or even set cluster_database to false.
While confusing part is whether Reverse is TRUE i.e. if you have NON RAC DB Binary and then you relink with rac_on option and now you have RAC enabled true. I am not clear on this statement.

Importing from an Oracle database converted from non-unicode to unicode - SSIS 2012

Hi,
I've some SSIS 2012 pkgs that read from a non-unicode Oracle database to a non-unicode SQL Server database.
Few days later, the Oracle database will be converted to unicode one and so I need to update the SQL database and the SSIS pkgs. Obiously no data conversion transformations are present in the pkgs. I'd like to avoid to add more of these data conversions.
As a first step, I'm trying to convert a SQL table to unicode format, but it isn't possible to convert non-unicode and unicode string data types.
I did not expect to have an error about the conversion from to non-unicode Oracle database (not yet converted) to unicode SQL Server database: a such conversion doesn't lost any information content. For me, it is right to have an error by from unicode to
non-unicode conversion.
Any suggests to solve this issue with a minimum development effort? Many thanks

Nope once you change datatypes to unicode you've to refresh metadata settings within SSIS packages for it to work fine. SSIS doesnt have the ability to do metadata changes at runtime. So someone has to update package metadata information to make them unicode
to make sure it works correctly after the changes.
What you can do is create test dbs in oracle and sql in uncode and create some modified packages based on it. Once you make changes to production dbs you need to move these modified copies also to production after making necessary config value changes like
servername,dbname,folder paths etc and then they will continue to work normally without causing any further downtimes to the customer.

Should I install the Client or Database binaries

I need to manage some Oracle Databases (10.2). Should I install the Client or Database Binaries. It seems the components included in the client changes. Right now I have the Oracle Client 11.1.0.6.0 installed and I do not see any admin too to managed the database like I saw in the Oracle 10g Clients. So confusing.
THanks,

Oracle client also comes in different flavor.. You can also install Oracle client with Admin utilities in case you are not going to create any database on the machine. If you will be creating any database, then you will need Oracle database binaries.

Can I use data guard to create a RAC standby database for a non RAC primary

Hi,
we need to RAC our production database but the normal methods will mean a long outage. It is possible to create a standby as a single node RAC database and when ready do a graceful failover to the standby database and open it for business. The next step would be to create another RAC node from this on the original server.
servers are already cluster aware, using ASM etc
Oracle 10.2

Yes, you will be able to setup RAC stnadby for a non-RAC Primary. For primary it just needs a available destination for redo shipping it doesn't matter whether it's RAC enabled or not. And ofcourse you are using 10.2 anyway only one node will be running MRP and that is too in standby mount mode.
However since you have are using You may follow below sequence.
1. Setup a new standby as RAC enabled.
2. Perform a switchover.
3. Shutdown the Old primary (which is standby now).
4. Install CRS and RDBMS on the old primary and it's new node.
5. Modify the cluster_database=TRUE and cluster_database_instances=<required number of instances>.
With above modification mount the standby database in standby mode and start MRP.
6. Introduce the database and instances to the OCR using SRVCTL add command.
7. Once you your database is synchronized with Primary do a switchover.
9. Now you can repeat step 3 to 6 on the other site too. <- if you need your secondary site to be RAC enabled too
10. Finally both the sites should be RAC enabled.
Hope this is helpful!!!

Database migration from non rac and non asm to RAC database with ASM

HI,
i have requirement to import one database ( db1) which running one node with out ASM and with out RAC , now i want to import that database with rman backup to another database ( db2) which running on different server with 3 node RAC and ASM ( disk group +DATA ) , can you please provide me the steps how i can migrate.? ( i have created db2 with dbca with RAC).

Sri,
This could be done multiple ways. Simplest for you is to use DBCA:

Hidden Database Items - Using Non-database Items

I am making my first form. It is based on a table having three columns, two are IDs (primary keys) for other tables ( org_organization_definitions and po_vendors ), and one is an enabled_flag containing either Y or N. In my form I need to hide the IDs of the underlying table, but display the organization_code and vendor_name from the IDs of the records from their respective home tables, and be able to query records by organization_code and vendor_name.
I have tried two methods:
In the first I created a block from the table with the ID and enabled_flag columns, and manually created text items for organization_code and vendor_name that are not database items and manually fill them in the post-query trigger of the block. The problem I ran into with this method was that I did not know how to use the manual text items for searching, and I could not get the LOVs to behave as expected as with database items.
In the second method, I created a view with all of the data that I needed to display, and based the block on that. Of course I cannot update or insert into the view, so I wanted to handle the updates and inserts manually with my own DML statements. With this method I have two problems, I don’t know how to bypass the form runtime not wanting to let me update values, and once I do, I am not sure how to manually go through each record to check to see if it has been changed or not.
I am not sure if either of my methods are the only two options or the best ways. Any help you can provide me with in this matter is appreciated.
Thank You,
Ryan

hi,
I have a requirement where I have to use existing database(OLTP) as my source to the SSAS cubes and then to build the reports.
Where for Cubes and Reports I uses SQL Server BI edition. But my existing source data will be in non BI database.
My questions are
1) Can I create Fact and Dimension Model in Non BI Db and connect the same to SSAS and SSRS? What you suggest?
2) Can I use cubes and reports without modifying the existing OLTP DB structure to fact and Dimension?
Thanks
Naveen
1. Yes. you can
It doesnt necessary need to set up a OLAP system. However making design inline with OLAP would be easier to implement in SSAS
2. Again yes
But using OLTP designed tables in SSAS/SSRS would require some additional overheads at querying level like referenced lookups in SSAS vs lots of joins in backend queries in SSRS.

Problem publishing database contents from non-unicode to unicode system

Hello everyone!
We just set up a new SAP WAS based on Netweaver 2004 as a unicode system. Out problem now is that we have a content management system on our non-unicode system and that we are publishing the contents via rfc to the WAS unicode system to display the contents online. the contents are stored in our own database tables.
The problem thereby is that many texts pasted from microsoft word contain special characters like bullets, long minus or low-9 quotation marks which are not correctly displayed in the unicode system / on the website. we already found out that it has something to do with the codepage. the sap notes say we should use 1160 instead of 1100 and that the transaction SPUMG would be helpful. but we are not able to select any tables there.
so now we do not know what to do exactly. do we have to change something in our non-unicode system or do we have to conversion in our unicode system. and what happends if content containing special microsoft word characters is published after the spumg conversion? do we have to to this frequently?
We would be glad if anyone could help.
Thanks a lot!

Hi Martin,
thanks for your quick answer.
You got me right. We have a local non-Unicode SAP HCM Netweaver 2004 system running a self-developed web based content management system / wiki. The texts entered in the bsp application are stored in a string field in our database table. Actually we publish the contents to a WAS 6.20 non-Unicode system with the same database tables to provide the content via BSP for the public. Everything is working fine including the special characters.
Now we want to replace the WAS 6.20 non-Unicode system by a new WAS 7.0/2004 Unicode system. But when publishing the contents via the same RFC function module to the new system the special characters seem to be damaged. We are not able to replace them with abap commands and when they are displayed on the website we only see "boxes".
If I get you right we have to run SPUMG on our nw 2004 non-unicode productive hcm system, right? but isn't there a danger to damage existing contents?
Best regards,
Stefan

Enable Archivelog Mode On 2 Node RAC DATABASE

hi,
We are having 2 Node Rac 10g Database Installed on Windows.
Currently the Database is in Non Archivelog Mode.
I want to convert it to Archivelog Mode.
I come to know the steps to convert cluster database to Archivelog mode.
i.e.
set archive parameters like Disk Location and Archivelog File format.
then Convert the database in Exclusive Mode
ALTER SYSTEM SET cluster_database=FALSE SCOPE=spfile;
then
C:\> srvctl stop database -d <Global_DB_SID>
then enable Archivelog Mode.

SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ALTER DATABASE SET cluster_database=TRUE SCOPE=spfile;
SQL> SHUTDOWN IMMEDIATE
C:\> srvctl start database -d <Global_DB_SID>
But I am confuse with Do i need to RUN this commands in both the nodes seperatly or only on any one node.
Please Reply,

I'm not sure why you have the non-standard service_name racdb2.
Somehow it looks like you both don't understand the RAC concept, and didn't understand my answer. I had to correct several things I already corrected in my previous response. I'm not sure why I'm not getting through.

Restore RAC database from non-RAC source - EBS R12.1.1

We have restored (PIT) a RAC database from a non-RAC (but ASM) source and I was wondering if that was a reasonable thing to do.
The reason I ask is that I seem to remember that in the upgrade to R12.1.1 the upgrade driver had a different list of jobs to do when the target was RAC vs when it was non-RAC... so is it possible the EBS R12.1.1 code is different for RAC (meaning we dont have the right code base in the DB since we restored a non-RAC source to a RAC destination)?
Disclaimer - I am NOT a DBA .. just trying to identify some potential problems we are troubleshooting.
Thanks in advance!
EBS R12.1.1
OEL 5
11gR2

We have a RMAN back up of the non-RAC database that was restored and PIT recovered on the RAC database.Is it a full database backup?
The "code" base I am referring to is all the db stored objects for R12 EBS .. database compiled code.Restoring the RMAN backup on the target node is not enough. Have you run AutoConfig or postclone? Does your instance know that this is a a single instance and not a RAC one?
I am nervous that there may be alternate versions of the code to run in RAC vs non-RAC .. for instance I know that some of the ASCP jobs use DBMS PIPES and that can be tricky with RAC and Concurrent Manager.. And when we did the upgrade to R12, pointing it @ RAC generated more and different jobs than when it was not pointed @ RAC .. so SOMETHING was different according to the APPS ADPATCH/ADADMIN utilities.Please explain in details what is the purpose of doing this restore and what exactly you are trying to achieve. What cloning procedure you follow to refresh the target instance?
Thanks,
Hussein

Are multiple PHYSICAL databases supported in one Oracle 10g RAC environment

Hi alls,
as of Metalink 220970.1 Oracle RAC is also supporting different databases in one cluster installation. RAC handles any resource as a service and it doesn't matter if these services belongs to only one or to different databases. You install the Oracle Clusterware only once and you create any service you want to make high available.
So is technically possible to install multiple databases on same Oracle Rac environment.
My doubts are related to SAP , does SAP certify such environments ?? we could have one SAP R/3 database and SAP BW database co-exist in a single Oracle RAC environment. or also co-exist SAP database with a non-SAP database (an already existing application) in the same Oracle Rac environment.
Any comment would be higly appreciated.
Silvio Brandani

We have ECC, BI, PI and Portal running on same Oracle RAC environment. We have one RAC for QA systems and one for PRD systems. We are not running any SAP applications along with Non-SAP applications on RAC. Keeping SAP and non-SAP apps separate would be a way to go.
Hope this helps.
Thanks,

Moving RAC/ASM to single-node non-rac SET NEWNAME not working

Good morning,
I'm trying to restore a rac/asm database to a non-rac environment to simulate disaster recovery under worst-case circumstances.

Thanks!

Hi,
I assume your problem is either in your pfile ( but you indicate you have removed all RAC settings), or in your control file.
I would recommend to remove the control files and create them later as soon as the datafiles have been restored, using the commands:
STARTUP NOMOUNT
CREATE CONTROLFILE REUSE DATABASE "OMST01" NORESETLOGS FORCE LOGGING NOARCHIVELOG
-- SET STANDBY TO MAXIMIZE PERFORMANCE
MAXLOGFILES 100
MAXLOGMEMBERS 2
MAXDATAFILES 1024
MAXINSTANCES 8
MAXLOGHISTORY 10210
LOGFILE
< your logfiles >
DATAFILE
< your datafiles >
CHARACTER SET <your character set>;So the steps are
Startup nomount with the pfile
Restore the datafiles using rman
Shutdown the database
Use above script to create the control files
It is possible you need to use the RESETLOGS option instead of the NORESETLOGS

Running OWB on 6 RAC databases on 4 shared nodes

Hi everyone!
I was wondering if anyone can help with a question I have around multiple OWB installations on RAC?
Background:
We are migrating 6 independent data warehouses / data marts onto one Exadata box. This machine has got 4 nodes, across which we will run 6 separate databases using RAC. Each database will span across all 4 nodes, and each of the databases will contain one of the independent data mart / data warehouses.
We understand that we will probably need to run 6 separate control center services on each node, and that there may need to be some fiddling around with log file names to get them all to start properly.
However; the question is where to install the OWB binaries!?
In our understanding, we need one set of OWB binaries per database, i.e. 6 in total. The actual databases will be run from just one set of local Oracle Database binaries on each RAC node, which means only four database binaries in total will be used to run 6 RAC databases across our 4 nodes.
Problem is, this means that there won't be enough OWB binaries to go around!! (6-4 = 2 missing!)
One alternative is to have 6 Oracle homes on each RAC node, i.e. one home per RAC database. I'm not a RAC expert - maybe this is even the preferred way of setting up the databases, regardless if we use OWB or not?
Comments / suggestions would be much appreciated!
Cheers

Hi,
We also have a 6 node rac where we settes up owb.
We went through a whole lot of problems but got it running finally(with service failover).
Basically you will need the binaries on all 4 of your physical nodes.
For the first node you can run through the normal installation (repository setu).
Thab you need to start the repository assistant on all other nodes in ordr to register them.
There are a lot of pitfalls with that installation and a lack od docunentation.
We've written an onstallation guide for an OWB rac setup where with we have now setted up 9 OWB repositories spreaded over 2 racs.
