Process to shutdown a EBS on RAC and impact on existing DR(Stand by)

I have to shutdown the 2 node RAC,2 node application for battery replacement.Which is having a DR on place.
>Shut down application on both the node
>Shut down rac database through srvctl
>Shutdown the crs through crsctl
What i need to to at DR which is on mount state during the production is down.
Dow i need to disable something/shutdown DR?

BO4 - Changing name of existing connection on repository and impact on existing unx universes

Hi,
If we have universes (unx ) which have connections and want to rename the connection, I know we can change the name of the connection on the repository via the repository resources in the Information Design Tool.
I notice existing universes which use the connection still have the old name for their connection shortcut.
Is there a way to synchronise so that if change a name of universe connection the names of connection shortcust on existing universe connections are automticallly chnaged to reflect the new name?
Thanks

HI
Changing name of existing connection not impact on existing unx universe, if backed connection CUID not changes, I think you can rename the existing connection in CMC .
Before doing test with sample example.

New Gl 0Fi_GL_14 and impact on existing _4 AP and AR datasources

We will be moving to new GL and I'm investiagting the 0FI_GL_14 Datasource for this purpose.I have couple of questions on this datasource.
I couldn't find any related AP and AR datasources for new GL. Does this mean we can continue to use 0FI_AP_4 and 0FI_AR_4 for AP and AR reporting ??
Our current dataflow for GL is 0FI_GL_4 -> GL_O02 ODS-> Custom cube
Since we have lot of reports out of the GL custom cube can we set our new path as follows so that we do not have to re create all the queries. This way we will still be existing cube with ne wGL datasource and ODS.
0FI_GL_14-> 0FIGL_O14->Existing customcube.
Points will definetley be awarded. Thnaks

Hi,
I had also done 0FI_GL_10 in the past with a similar concept as yours and it did work. Plus, during that time I had researched on AP and AR datasources and I don't think there are any new ones like we have for GL. I believe the new datasources for GL are because of the 2 new tables in ECC (FAGLFLEXA/FAGLFLEXT).
I think the solution that you are trying to build should work, will need some testing though, but there is a lot more to offer in the GL_14 datasource than the old GL_4, so you might want to build a new cube to accommodate that. Or you can update 2 cubes from the GL_14 ODS, 1 would be your existing one and other would a new cube, so when the users are ready you can migrate them from the existing to other.

Need to shutdown GG process if 1 node of the RAC is shutdown?

if only 1 node of the 2-node RAC cluster is shutdown, Does GG have to come down as well or can it run against the 1 node that is up.
Thanks

Apologize for wrong answer to this post, due to site network issues wrong page was opened, hence wrong answer was posted earlier.
Hi,
If one of the node is down, OGG Extract also breaks down as it is unable to process that particular redo thread. As you are aware, in a RAC environment, the Extract process uses threads, one for each redo thread in the RAC cluster.
Hence the only way to restart the Extract is to exclude the node(redo thread) by using THREADOPTIONS PROCESSTHREADS EXCEPT <thread spec>.
Example: THREADOPTIONS PROCESSTHREADS EXCEPT 2
Extract threads are mapped to redo threads, so while excluding the thread please verify the mapping correctly and exclude the right thread.
SQL> select distinct THREAD# from gv$log;
Caution: Excluding any of the Extract threads from being processed excludes that data from being synchronized with the target tables.
Once the node is back online, you could comment out the above parameter in the Extract parameter file and restart the Extract to process all the redo threads in RAC.
Hope this information helps.
Thanks & Regards

EBS on RAC

Hi Deareast Friends,
I am confused about EBS on RAC.
Suppose I want to install EBS on a double RAC set-up meaning the
APPS server tier is clustered (RAC) and the Database tier is also clustered (RAC).
Are these two RAC (the apps server and db server) have the same configuration style?
set-up? Meaning they both use CLUSTERWARE and ASM/OCFS for the shared
storage?
Thanks a lot,
krissy

You might review the following with reference to RAC;

Hope it clarifies;
You choose whether to install the system on a single node (machine), or across multiple nodes. All servers and services, except for the RDBMS, are commonly referred to as application tier servers (and services). An application tier is a logical grouping of servers based on system architecture and server functionality.

Is there RAC too in the apps middle-tier servers?My assumption is that it is being confused with load balancing.
Load balancing distributes processing and communications activity evenly across
networks so that no single node is overloaded. For example, processing loads can vary significantly for forms requests, because it is difficult to predict the number of requests at a given time. Load balancing can spread these requests across multiple Forms servers, so that the requests are forwarded to the "least loaded" server.

Problems with RAC and XA: Fallback

Hello,
we are seing problems with RAC and XA (Tuxedo 11, DB 11.2), specifically encountering "ORA-24798: cannot resume the distributed transaction branch on another instance".
The first scenario relates to fallback after a RAC node failure. There are two servers, S1 and S2. S1 makes an ATMI call to S2. Both servers are in the same Tuxedo group, using TMS_ORA. RAC is set up for failover (BASIC), no load balancing.
The sequence is:
- S1 and S2 are connected to the same RAC node n1. All is well.
- RAC node n1 fails. S1, S2 and the TMS_ORA all fail over to RAC node n2. After the failover has happened, all is well.
- RAC node n1 recovers. All is still well (as there is no automatic fallback).
- S1 (or S2) is restarted (either intentionally or because of a crash). Since n1 is up again, S1 connects to n1. Now we get ORA-24798. Permanently.
S1 is connected to n1 and S2 is connected to n2. Since both are in the same group, both use the same XA transaction branch. When called, S2 attempts to JOIN the transaction branch that S1 started. But the DB (11.2) does not allow the same branch to span more than one node. Hence the ORA-24798.
This seems to be a severe limitation in the combination of Tuxedo, XA and RAC. It basically means we still have to use DTP services, even with Tuxedo 11 and DB 11.2. Or are we missing something?
We could put S1 and S2 into different groups, but that seems to be inefficient, and not practical for a real application (10s of servers).
I am extrapolating from this that RAC load balancing would also not work, as S1 and S2 could be connected to different RAC nodes.
Roger

Roger,
When using an external transaction manager such as Tuxedo you should still declare Oracle services as DTP services when using Oracle Database 11g. The Tuxedo documentation is not clear about this. The relevant 11gR2 RAC documentation is at http://download.oracle.com/docs/cd/E11882_01/rac.112/e16795/hafeats.htm and states
"An XA transaction can span Oracle RAC instances by default, allowing any application that uses the Oracle XA library to take full advantage of the Oracle RAC environment to enhance the availability and scalability of the application.
"GTXn background processes support global (XA) transactions in an Oracle RAC environment. The GLOBAL_TXN_PROCESSES initialization parameter, which is set to 1 by default, specifies the initial number of GTXn background processes for each Oracle RAC instance. Use the default value for this parameter clusterwide to allow distributed transactions to span multiple Oracle RAC instances. Using the default value allows the units of work performed across these Oracle RAC instances to share resources and act as a single transaction (that is, the units of work are tightly coupled). It also allows 2PC requests to be sent to any node in the cluster.
"Before Release 11.1, the way to achieve tight coupling in Oracle RAC was to use Distributed Transaction Processing (DTP) services, that is, services whose cardinality (one) ensured that all tightly-coupled branches landed on the same instance—regardless of whether load balancing was enabled. Tightly coupled XA transactions no longer require the special type of singleton services to be deployed on Oracle RAC databases if the XA application does not join or resume XA transaction branches. XA transactions are transparently supported on Oracle RAC databases with any type of service configuration.
A"n external transaction manager, such as Oracle Services for Microsoft Transaction Server (OraMTS), coordinates DTP/XA transactions. However, an internal Oracle transaction manager coordinates distributed SQL transactions. Both DTP/XA and distributed SQL transactions must use the DTP service in Oracle RAC."
This issue came up earlier this year in another newsgroup thread at https://forums.oracle.com/forums/thread.jspa?threadID=2165803

Full database exp/imp between RAC and single database

Hi Experts,
we have a RAC database oracle 10GR2 with 4 node in linux. i try to duplicate rac database into single instance window database.
there are same version both database. during importing, I need to create 4 undo tablespace to keep imp processing.
How to keep one undo tablespace in single instance database?
any experience of exp/imp RAC database into single instance database to share with me?
Thanks
Jim
Edited by: user589812 on Nov 13, 2009 10:35 AM

JIm,
I also want to know can we add the exclude=tablespace on the impdp command for full database exp/imp?You can't use exclude=tablespace on exp/imp. It is for datapump expdp/impdp only.
I am very insteresting in your recommadition.
But for a full database impdp, how to exclude a table during full database imp? May I have a example for this case?
I used a expdp for full database exp. but I got a exp error in expdp log as ORA-31679: Table data object "SALE"."TOAD_PLAN_TABLE" has long columns, and longs can not >be loaded/unloaded using a network linkHaving long columns in a table means that it can't be exported/imported over a network link. To exclude this, you can use the exclude expression:
expdp user/password exclude=TABLE:"= 'SALES'" ...
This will exclude all tables named sales. If you have that table in schema scott and then in schema blake, it will exclude both of them. The error that you are getting is not a fatal error, but that table will not be exported/imported.
the final message as
Master table "SYSTEM"."SYS_EXPORT_FULL_01" successfully loaded/unloaded
Dump file set for SYSTEM.SYS_EXPORT_FULL_01 is:
F:\ORACLEBACKUP\SALEFULL091113.DMP
Job "SYSTEM"."SYS_EXPORT_FULL_01" completed with 1 error(s) at 16:50:26Yes, the fact that it did not export one table does not make the job fail, it will continue on exporting all other objects.
. I drop database that gerenated a expdp dump file.
and recreate blank database and then impdp again.
But I got lots of error as
ORA-39151: Table "SYSMAN"."MGMT_ARU_OUI_COMPONENTS" exists. All dependent metadata and data will be skipped due to table_exists_action of skip
ORA-39151: Table "SYSMAN"."MGMT_BUG_ADVISORY" exists. All dependent metadata and data will be skipped due to table_exists_action of skip

ORA-39111: Dependent object type TRIGGER:"SYSMAN"."SEV_ANNOTATION_INSERT_TR" skipped, base object type VIEW:"SYSMAN"."MGMT_SEVERITY_ANNOTATION" >already exists
and last line as
Job "SYSTEM"."SYS_IMPORT_FULL_01" completed with 2581 error(s) at 11:54:57Yes, even though you think you have an empty database, if you have installed any apps or anything, it may create tables that could exist in your dumpfile. If you know that you want the tables from the dumpfile and not the existing ones in the database, then you can use this on the impdp command:
impdp user/password table_exists_action=replace ...
If a table that is being imported exists, DataPump will detect this, drop the table, then create the table. Then all of the dependent objects will be created. If you don't then the table and all of it's dependent objects will be skipped, (which is the default).
There are 4 options with table_exists_action
replace - I described above
skip - default, means skip the table and dependent objects like indexes, index statistics, table statistics, etc
append - keep the existing table and append the data to it, but skip dependent objects
truncate - truncate the existing table and add the data from the dumpfile, but skip dependent objects.
Hope this helps.

Install Real Application Clusters (RAC) and Automated Storage Management (A

Do I have to install Real Application Clusters (RAC) and Automated Storage Management (ASM) for ETL
I have installed Oracle 10g Release 1 on WIndows 2000 with datawarehousing option.
Is it ok
Or do I need to install Oracle database again.
Please help

Greg,
From what you describe you did exactly the right thing. The runtime platform service will by default run on DWH01, but you can shut it down on that node and have it run on DWH02 (in case you wanted to bring down DWH01 but still run Warehouse Builder processes). Note that we strongly recommend using the net service name in the location registration in the deployment manager (so that you automatically take advantage of the client-side load balancing feature of RAC (as well as the server-side load balancing)).
Thanks,
Mark.

Clean way to De-register/De-commission the database with EBS from RAC/Cluster.

Hi,
We have a database with EBS on RAC. We are looking for Clean way to decommissioning the database from the cluster. We tried earlier, but when we again installed a fresh database on that server some how we had issues with the user oracle in cluster configuration files.
Early response is highly appreciated.
Thanks,

Hi Hussein,
We have two node db and two node application server in a cluster environment.
We want to Remove/Decommission JUST DATABASE, APPLICATION related all files from the cluster. Cluster files should not be effected. After removing them we want install a fresh Db and Application on the same cluster.
Looking for any standard method for decommissioning.

Clone multi-node RAC and ASM to single node

Hi everyone.
I need clone system with 3 application server and 2 oracle database RAC and ASM to single-node. The operating system is RHEL 5.
I see some metalink notes, but we can't found nothing. I find notes with multi-node to single-node, but nothing with RAC to non-RAC.
The eBS version is 11.5.10.2 and database version is 10.2.0.3
Is possible this clone?
Thanks very much.

RAC and ASM with geographically seperated disks

We are planning to use RAC and ASM with four nodes. The two nodes will be at one location and another two nodes at different location. The ASM disks also will be available locally. Is it possible to configure ASM with geographycally serepared disks.
We are thinking of two RAC and ASM setups with two nodes each and streams replication between the RACs.
I want to know what is the best method to implement. Is it RAC with four nodes OR two RACs with two nodes each and streams replication between the RACs.

Apart from the latency issue, which has been mentioned by others, you also need to mirror your disks between the two sites and be very careful about split brain scenarios under node or site crashes.
You need to mirror the disks between the sites in case one site crashes completely and loses all network access. The only way the second site can carry on is if it has access to all the data disks, and the cluster control disks (terms vary for this, such as quorum or voting disk). If you do not mirror you simply do not have a resilient design. Resilience is about eliminating all single points of failures, which means duplicating everything i.e. mirroring.
And mirroring between two remote sites adds more volume to the data traffic between the two sites. And it would need to be synchronous rather than asynchronous to guarantee no data loss. And your commits for each transaction would be limited by the round trip time to write to the remote site and get the acknowledgement back.
Split brain is something you need to avoid with remote clusters, and local clusters too. If the network goes down between the two sites and both sites have local copies of all of the data and cluster control disks, which site becomes the primary and which one becomes the standby? You cannot have both sites coming back up as primary with active databases and accepting transactions! At this point you have split brain, and each side is processing transactions independently, and both databases are now deviating from each other with different data changes.
I don't think a 4 node RAC environment split across geographical distances is really viable, except under small transaction volumes, and where response time (transaction time) is not critical. If you have high volumes and need fast transactions then you need to only use local RAC configurations, and replicate between the two sites asynchronously. DataGuard is easier, but you need to decide if you need Streams and how to make it work for you.

Tnsnames configuration for RAC and dataguard

Hi everyone,
I have an environment with RAC and dataguard (production is RAC, standby is single instance) and I was wondering what is the best way to configure the clients (since I have quite a few and I don't want to change their tnsnames if I need to failover to the standby database).
Now, I need to have both RAC nodes of course, the question is what I should do with the standby...
The problems are:
1. If I add the standby as another address, 1/3 of the connections will get to it and I don't think it's a good idea
2. I can disable the load_balance, but then all connections will go to the first node's listener
3. After a failover, if the RAC nodes are down, it will take a long time to connect (the servers will not respond and the client will wait for timeout if it tries to connect to the RAC nodes first, only after the timeout it will try the standby and succeed)
Any ideas and suggestions will be appreciated.
Thanks,
Liron

Hi Robert,
I agree that the standby should be up, but you have to admit that if it is down it should not delay connections to the primary...
About the DNS, it's not that I don't trust the SA, but this is an environment for a customer so it should be as independent as it can be. So the failover process will be easy and fast. I don't know if I can get DNS permissions, but that's a good idea...
A question that can be derived from this:
assuming that I use observer to have an automatic failover, how should I configure my TNS? If the standby will become the primary automatically, I have to configure the clients to connect to the activated standby automatically. With no DNS changes or anything manual.
I guess in this case, my best option will be with LOAD_BALANCE=off, some of the clients will have RAC-NODE1 as first address and some will have RAC-NODE2, the standby will be the last address and we'll suffer the timeout if the primary will be down when connecting to the activated standby.
If anyone has other ideas, it would be great.
Thanks,
Liron

Oracle EBS R 12.0.6
Database: 11.1.0.6
Windows 2003 server

Was this working before? If yes, any changes been done recently?
Can you find any errors in the database log file?
Do you have any invalid objects?
Did AutoConfig complete successfully at the database tier node and the application tier node?
Please also see these docs.
"You Have Encountered An Unexpected Error" - JBO-30003 Error While Login To Oracle Applications With Database RAC Implemented [ID 465812.1]

RAC and Grid Computing

Hi,
I am trying to understand the connection between RAC and Grid Computing.
In RAC, we can have multiple instance of the same physical database and if all these instances are running on n* separate machines then we have n+ set of processes to take care of computation.
Isn't this summarise the Grid computing as well or is it something entirely different. Please share.
Thanks in Advance

Hi,
Billy already answered well.
Litte Note:
Timeline of Oracle Databases:
1992: Oracle version 7 appeared with support for referential integrity, stored procedures and triggers.
1997: Oracle Corporation released version 8, which supported object-oriented development and multimedia applications.
1999: The release of Oracle8i aimed to provide a database inter-operating better with the Internet (the i in the name stands for "Internet"). The Oracle8i database incorporated a native Java virtual machine (Oracle JVM, aka "Aurora").
2001: Oracle9i went into release with 400 new features, including the ability to read and write XML documents. 9i also provided an option for Oracle RAC, or "Real Application Clusters", a computer-cluster database, as a replacement for the Oracle Parallel Server (OPS) option.
2003: Oracle Corporation released Oracle Database 10g, which supported regular expressions. (The g stands for "grid"; emphasizing a marketing thrust of presenting 10g as "grid computing ready".)
2005: Oracle Database 10.2.0.1—aka Oracle Database 10g Release 2 (10gR2)—appeared.
2007: Oracle Corporation released Oracle Database 11g for Linux and for Microsoft Windows.
Future (*Just a guess*): Oracle Database will release version 12c. (The c stands for "cloud"; emphasizing a marketing thrust of presenting 12c as "Cloud Computing ready".)
Oracle has released products with "C" of the "Cloud" (e.g Oracle Enterprise Manager 12c)

MySQL Cluster

Ha ha, most amusing.
I suggest you try googling for answers to these things. This is a site dedicated to the Oracle database, the questions are answered by volunteers (not Oracle employees) and we are primarily geeks rather than marketing droids. If you have a specific Oracle question please feel free to post anytime.
Thank you for your interest.
Arrivederci, APC
