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.
Just let me know if you require detailed information - maybe we can share our guide.

Policy Managed RAC database instance on different node

Dear All,
Recently we have upgrade our production database from 2 node 11.2.0.1/Solaris 10 Sparc to 2 node 12.1.0.2/Solaris 11.2 Sparc
earlier was Admin managed database, now we have created Policy managed database.
Instance_1 running on node_2
Instnace_2 running on node_1
how to switch the instance to correct node or what is the concept , why it running vice versa even though assign ORACLE_SID properly.
please clarify me.
oracle@zhovm-proddb2:/u01/app/12.1.0.2/grid/bin$ srvctl status database -d proddb

Thanks.

Thanks John,
How the cron jobs takes care, is there any different is there between Admin Managed & Policy Managed
Thanks.
Muba
I don't know what your cron jobs do. If (for example) they logon to the database through a service published by the scan listeners, they will be happy. If they logon using a deterministic connect string, you have a problem - a problem caused by mis-using the system.

Can I put ALL my applications into one RAC database

Dear all,
Is it possible to share all of my workloads between a single RAC database or would it be better to run more than one RAC database on the the same cluster if they have very different characteristics (e.g. OLTP vs DSS or sensitive vs non-sensitive data). Oracle seem to imply that they have cut down their number of physical databases drastically but have they been able to do that because the workload is very homongenous, i.e all ERP stuff? Should it be possible to accommodate all workloads by having different instance parameters or does that defeat the object of being able to fail over a service from one instance to another?
Views/experiences please.

Hi, generally it is possible to put everything into one RAC database, especially if they share the same data. So you do not have to transport data from one database into the other.
Furthermore the resource allocation can perfectly be addressed with the resource manager of the database together with services. The workload has not to be homogenous.
However it might make sense to connect the DSS users to different nodes in the cluster than the OLTP users (via. services).
On the other hand there might be non technical issues which would make seperate databases more attractive. Like Patching could mean downtime of all applications. Like certifications of software, which would not allow you to upgrade your database, like ERP needs 10.2.0.2 while DSS would be better off with 11g) and so on.
There is really no right or wrong.
Still to get the most of the benefits out of a cluster the fewer databases you have.

RAC database Migration

Hi Experts,
I need some advice related to the Migration of RAC database, we have to migrate several RAC & Single-Instance databases from existing HP Itanium servers to Superdome2.
Initially I thought of going with "addnode" for new Servers as additional Nodes to the existing RAC database then remove old Nodes for RAC databases migration, but there are some limitations in our evironment,
1. There are no free IP addresses available to assign to new nodes from the existing IP segment.
The IP Range (1 - 255) is divided into into several small segments of 16 IPs in each segment, and the segment in which the existing 2Node RAC DB is completely occupied and there is no free IP Available.
If the new Node have IPs addresses from different segment in the same Subnet(IP Range) can it be added to the existing cluster?
and if we cannot find any IP in that Subnet then can the nodes with the IPs from other Subnet be added to the Existing Cluster?
2. To add a node to the existing RAC cluster, the new node should be exactly same, OS version, OS Patches...
Our existing rx Itanium servers have "*HP-UX 11.31 Mission Critical Operating Environment*" for One 2 Node RAC Cluster and "*HP-UX 11.31 Enterprise Operating Environment*" for for another 2 Node RAC Cluster, but the HP Superdome 2 will have the Latest "*HP-UX 11.31 Data Center Operating Environment*"
Can we proceed if there are some diferrences in OS patches...?
Please see the Existing Environment Details below:*
Prod 1 DB *2 Node RAC Cluster* :
Hardware: rx 8640 Itanium Server
OS: HP-UX 11.31 v3 Mission Critical Operating Environment
DB Version: Oracle 10.2.0.2
Prod 2 DB *2 Node RAC Cluster*:
Hardware: rx 8640 Itanium Server
OS: HP-UX 11.31 v3 Enterprise Operating Environment
DB Version: Oracle 11.2.0.1 (2 Node RAC)
Prod 3 DB *2 Node RAC Cluster*:
Hardware: rx 6600 Itanium Server
OS: HP-UX 11.31 v3 Enterprise Operating Environment
DB Version: Oracle 11.1.0.6.0 (2 Node RAC)
TARGET DB Environment for All the Databases will be;*
Hardware: HP SUperdome 2
OS: HP-UX 11.31Data Center Operating Environment
DB Version: Oracle 11.2.0.3 (2 Node RAC)
Also, all the 3 RAC databases are in Extended/Stretch RAC Cluster configuration and the new Superdome Env will also be in Extended RAC Cluster Configuration.
Kindly advice what strategy should I follow for the Migration, waiting for your kind reply.
Any help will be highly appreciated.
Thanks in Advance.

I am struck by your post with a couple of thoughts.
1. Even though high availability appears to be something you are willing to invest substantial money in obtaining ... no one think patching important.
2. Even though you've spent a substantial sum of money on hardware and software ... no one thinks networking important enough to address the lack of appropriate network infrastructure.
Personally: I'd advise refusing to do the work until management makes the very small investment necessary to doing it correctly.

Running an external job at the specific node out of a 2 Node RAC database.

Hi. all.
I created a job , which runs an external script, by using dbms_scheduler.
Our database is 2 node RAC database(10.2.0.2.0).
The external script exists at a only one Node(Node 1).
select status,instance_id, additional_info
from dba_scheduler_job_run_details
where job_name='TEST_EXPORT_JOB'
shows that jobs which run on Node 2 failed.
Of course, the external script does not exist on Node 2.
I would like to force the job to ALWAYS run on Node 1.
How can I do that? Is there any ideas?
Locating the script on Node 2 is not the option.
Best and Regards.

Hi,
In the upcoming 11g release there is an easy solution for this - a new attribute instance_id for a job.
For 10g there is a workaround. Basically you create a service with just the one instance you want the job to run on. Then create a job class pointing to that service. Finally have your job be in the job class you just created.
If you create a service and job class per instance you can get jobs to run under whichever instance you want.
Hope this helps,
Ravi.

Is X-windows and GUI desktops supported on the ODA "engineered system" running a RAC database? If it is, what is the yum command needed to install the X-windows, Gnome, and KDE package groups?

Is X-windows and GUI desktops supported on the ODA "engineered system" running a RAC database? If it is, what is the yum command needed to install the X-windows, Gnome, and KDE package groups?

While I agree with the direction of the suggestions with installing packages for X-windows, we do not have a blanket 'apply any package' recommendation.
In particular we do not support altering the kernel (although we do have exceptions which we review on a case by case basis).
Basically, if the you want to alter functionality that would not impact core functionality you are usually fine.
A good guideling is : The more dependencies that there are between the package / rpm you are considering using the higher the potential impact on functionality - meaning higher chance for problems
Note: We do use VNC including Real and Tiger regularly , but we have no hard recommendation on how you may want to use X-windows. I have never seen a limitation other than comments on bugs
or incompatibility within the X-window product itself with certain kernel levels.
Patching may overwrite some packages that you may install, however, _depending on packages/rpms added_ there is also the possibility that you will break existing functionality to the point
that patching itself will fail ( we have already seen a few cases of this in which case the proper mitigation is to remove / roll-back any alterations to the ODA before patching, and then adding the packages/rpms
back after the patching is completed.
From what you are discussing the impact should be low without conflicts, but please consider the above, and if you have specific packages which you consider potential problems
please create an SR so that we can review packages / rpms on an individual basis.
Once again: the main criteria for not supporting rpms is regarding the kernel itself

Need suggestion regarding drop RAC database of 11g

Hi All,
I have 11gR2 RAC environment setup. Database required recovery and I have no backup, based on support engineer guidance I restore the database using some hidden parameters though its a corrupted db so I need to rebuild. For rebuild purpose I took expdp of entire database and then drop it. I had drop through "dbca" , db was open and I run "dbca" and select drop database option, at one time it showing me warning/error ORA-01586:database must be mounted EXCLUSIVE and not open for this operation but after that drop was run perfectly.
but when I check the ASM disk status , it still show as it is , I mean no change in their free_space column, I also verified through asmcmd command and all the Datafiles are still there.
I want to cleanup asm disk which are still fillup with dbfs and I thought that would be cleared by dropping database but no my assumption was wrong.
can any one suggest me what to do if I want to make free space in asm disk which was allocated for dbf files?
Thanks in advance.

Help needed in deleting nodes from RAC database

Our DB is 10g RAC database and the servers are Window 2003 server. Initially the database was configured to have 4 nodes. For some reason we stopped the instances in the first two nodes and the current database is running on node3 and node4. I queried the v$thread view and it shows 3 records. Thread 2 is closed and disabled. Thread 3 is open and public and thread 4 is open and private. Now we need to disconnect nodes 1 and 2 from RAC db and cluster ware (We use Oracle cluster ware) and plan to use those two servers for other purposes. Although I read through the Oracle doc regarding deleting node from RAC “11 Adding and Deleting Nodes and Instances on Windows-Based Systems” and wrote down the steps we need to take but I am still not comfortable in doing it since it is production env and we don’t have any dev env to practice those steps. So I would like to borrow your experiences and your lessons learned while you were doing those. Please share your thoughts and insights with us.
Thank you so much for your help,
Shirley

what's your full version? I can warn about specific issues in 10.1.0.3 and 10.2.0.1 - for example, in some cases (depending on how the listener was configured), it will be impossible to delete the listener for the deleted node. Known bug.
To avoid many many known bugs, you may want to upgrade to at least 10.2.0.2 before removing a node (from my experience, this is the first stable RAC version).
In any case, deleting a node is a rather delicate process. I really really recommend practicing. Take any pc/laptop, install VMWARE, define two virtual machines, install RAC and remove one node. It will take you an extra day or two, and could save your production.

How to install Oracle 11.2.0.4.0 Rac Database on Grid Infrastructure 12.1.0.2.0 (Windows 2012 R2)

Hi all.
This is the scenario:
I have a 2 node cluster Microsoft Windows 2012 R2 x86_64, the nodes are part of domain.
Installed Oracle 12cR1 (12.1.0.2.0) as follows:
Installation done using domain administrator named "installoracle" that has been EXPLICIT promoted to local administrator in both nodes.
One domain user named "oracle12c" with no administrator privileges neither in the domain or nodes.
Installation, after a lot of customization in the OS of the nodes, has gone ok, perfect indeed, not even a warning during runinstaller execution.
All services and resources are up & running, I have rebooted nodes and all comes back ok in place. In windows services I can see some services started with "oracle12c" user, and all windows groups: DBA, SYSKM, etc, has been created.
Now I have to install Oracle RAC database in 11gR2 version (11.2.0.4.0) to accomplish with application requirements.
So, I execute runInstaller (setup.exe) logged as administrator via domain administrator "installoracle" (the one that was able to do the smooth 12c GI installation) and the gui comes with out problems, but at 4th screen the one in which you have to choose what kind of installation you want to do (Single, RAC or RoN) I select RAC option, the gui returns error: crs is not running in the local node...
Finally, in order to deliver some database 11.2.0.4.0 for my customer, I try to do installation of SW for Single Node, I did using "installoracle". The sw has been installed in one of the nodes. Then I have created a database and I have stored datafiles in ASM (this ASM is part of 12c clusterware) and also register the 11gR2 single instance database in the Grid Infrastructure listener
So, whats next??? Why is this behavior??? I did similar installations in Linux/Solaris with no issue (well as everyone can imagine, always there are some issues, but when solved you got GI in 12c and databases in the release that you want 12c, 11g, 10g...)
Any clue?
Thanks in advance!!
Best Regards!!

To go back to old version (without changing compatible parameter), you can perform downgrade.
Instructions are available at
How to Downgrade from Database 11.2 to Previous Release (Includes 11.2.0.4 - 11.2.0.1) (Doc ID 883335.1)
In this case you will having all the data file including the new one.
But remember database may not be in the same status as before (Before upgrade). it may have invalid objects of higher version after downgrade.
Downgrade is applicable only to successfully upgraded databases. In case upgrade faced some issue, do not try downgrade there.
Your second approach it not correct. Note that each datafile header will have db version. We can not open database in normal mode when header version and binary versions are different.

Not able to start one rac database

We had a 4 node RAC(11.2) environment in RH Linux.
it was running fine. By mistake we change the owner of the mount point where oracle clusterware and database installed on first node.
chown -R oracle:oinstall /u01
chmod -R 775 /u01
Due to this all services went down.
Later we change the owner, as it is on node2 and restart the services and server.
Now all the services are working fine. But oracle database is not coming up.
It is not able to read the spfile from ASM.
It is giving the error:

This error means that the hostname or IP address used in the TNS connection string, failed to resolve or connect.
Your client is making two connections. The first connection is to the SCAN listener. It matches a db instance for your connection request based on service requested, available registered service handlers, load balancing, and so on. It then send a redirect to your client informing it of the handler for that service.
Your client then does a second connection to this service (a local RAC listener that will provide you with a connection to the local RAC instance). This is what seems to be failing in your case.
The SCAN listener's redirect uses the hostname of the server that the local listener is running on. Your client needs to resolve that hostname (of a RAC node) to an IP address. This likely fails.
You can add the RAC node hostnames to your client platforms hosts file. The appropriate action however would be to ensure that DNS is used for name resolution instead.

Another RMAN duplicate problem - RAC database to single instance

Hi,
I have a problem with the RMAN duplicate procedure and was hoping someone can help.
I would like to create a duplicate of our production RAC database on a separate, stand-alone, database server on another site. This duplicate will be used for intensive querying by another business unit who I don't want to have access to our production database.
My procedure goes like this:
1. Create a disk (not ASM) based backup of the datafiles and any archived redo logs:
"run {
allocate channel d1 type disk;
backup format '/u02/stage/df_t%t_s%s_p%p' database plus archivelog delete input;
release channel d1;
2. Tar and scp these files to the same location on the stand-alone database server.
3. In the meantime, work has been happening on the production database and further archived redo logs have been generated. I don't really care about these logs for the purposes of the duplicate however, I just want to duplicate to the point of the recent backup. To do this, I run the following SQL to determine the sequence number that I should be duplicating up to:
"select max(sequence#), thread# from v$archived_log where deleted='YES' group by thread#;"
4. Duplicate the production database to the stand-alone database (all the SQL Net stuff is working).
"run {
set until sequence (value returned by above SQL statement);
duplicate target database to XXX;
However, my problem arises because I don't know how to handle the fact that there are two threads. I understand that each thread relates to one of the RAC instances, I just don't know which one to specify for the duplicate. We have a database service which the client application connects through, and that service runs on on or other of the instances. Should I just care about the logs from the instance where the service is currently running?
Am I even approaching this is the correct way?
I look forward to any help that people may be able to offer.
Regards,
Phil

You can see that the highest sequence number is 9750 of thread 1, and that the Low and Next SCNs are 569259816 and 56926111. However, when I look at the output of the RMAN duplicate command:
contents of Memory Script:
set until scn 569505448;
recover
clone database
delete archivelog
executing Memory Script
executing command: SET until clause

you can see that something is setting the recovery SCN to 569505448 which higher even then any of the archived logs mentioned above. If I select current_scn from the production database, this gives me 569528258 which is closer to the value which RMAN is expecting to recover to than any of the archived redo logs.
Can you think what might be causing RMAN to try to recover to this value? and why does it appear to be ignoring the SET UNTIL SEQUENCE command?
Cheers,
Phil
