• Configuring multiple services in a single instance database

  Dear all,
  
  I would like to create names from multiple services for a single instance oracle database (10.2.0.3 on IBM - AIX 6.1). I tried to search on the net, read the documentation, as well as on the metalink but couldn't find something relevant to the single instance database.
  
  Say I have two users, userA and UserB, for which I would like to use the two services (ServA and ServB) to connect to the same database to single instance.
  
  Any help in this direction is appreciated.
  
  Concerning

  ALTER system set service_name = 'ServA, ServB. '

  in your tnsnames.ora to designate either service_name = "ServA" or service_name = 'ServB.

  It is very difficult to believe that you can't find this in the documentation, and my suspicion is that you it didn't look at all.

  Hello

  You can take a look at http://taliphakanozturken.wordpress.com/2012/07/20/how-to-restore-10g-rman-backup-to-11g/

  You will need to change the name of db only after the database was opened after the upgrade and other steps.

• P2V one resource to Cluster MS and not to the cluster nodes

  Hello!

  We are looking to do a P2V on our file servers, which are all 2 node A / P SAN connected MS Cluster. I see articles where people work to convert the cluster nodes themselves and then have the MS Cluster running on ESX - this isn't what I want to do.

  I've not seen any (covered by a research brief) mention of any attempt to make a virtual server Cluster MS. P2V conversion Looks like it is the best deal if it worked.

  So I FS1 as the virtual resource with N1 and N2 as nodes.  Can I run a P2V of FS1 crowd for a disk system to capture all the action, then just RDM the SAN LUNS to the VM FS1 newly created? Or am I stuck with the creation of a third node, clustered, expelling the original, closing nodes cluster services and then rename or uses DNS to point to the FULL FS1 domain name?

  Thank you!

  I know that sounds a good idea but any time
  I tried P2V ING I ended up regretting the MSCS clusters. For the file
  & Print sharing there is some direct negative side effects but for
  The SQL cluster, it is very messy. You can not P2V the virtual server name
  (FS1) directly, you must break the cluster and migrate the
  individual nodes. But as I said it's a bad idea in any case.

  If these are just some cluster file server then the easiest thing to do
  is just export actions (they are just a registry key), build a new
  clean the VM, attach the existing data as a RDM disk and import the
  registry keys. Once your happy that it work, rename the machine as
  the former name of virtual node.

• Unable to save 12 ch. single instance 11g GI listener

  5.11 RHEL 64

  2 node RAC

  IM - 11.2.0.3.9

  DB_home1 - 11.2.0.3.15

  DB_home2 - 12.1.0.2

  I recently installed the 12.1.0.2 as a single instance on node 1 of the cluster. When you create the database in step 7 to record the listener, the listener SCAN 11 g has not been shown. I thought no matter, I'll just do the recording manually later.

  End of installation and DB creation complete, and I can't save the 12 DB to the listener to 11g. RAC instances have the value of the LOCAL_LISTENER parameter that follows:

  LOCAL_LISTENER = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST=node1.pub.com) (port = 1521)))

  I tried to adjust the same setting in the 12 c DB, still no change. Restarted the listener, 12 c instance, nothing works. I thought that maybe there was a compatibility issue when using a lower version for the listener, but I can't seem to find a doc in metalink to provide a matrix that verifies this. No message or trace files generated in newspapers for both instances. I don't want to manually change the listener.ora GI unless it's the only way, and I can't find any solid documentation within Oracle to indicate that this would be the only way to solve this problem. Any help would be appreciated.

  The GI version must be the same or greater than the version of database

• Running the Single Instance and RAC on the same server of different homes.

  Hi guys,.

  I already have 4 node RAC12c installed on OLE 6.

  I'm planing on some of my other 12 single instance databases on other migration for RAC nodes.

  Please correct me here if I am wrong...

  My understanding is that, to be able to use DBCA or rconfig for conversion of database instance RAC, the only instance and RAC cluster must run on the same server or machine node.

  Thanks to this understanding... Am planing on the installation of a binary single instance on one of my cluster node node1 say and then use RMAN to duplicate the single instance or just an RMAN restore from the node of the instance that is unique to this node1. Am capable of this plan must then use DBCA or rconfig to convert the CARS database.

  Now, my question is can I run a single instance and RAC on the same server for different homes with different database ports?

  2. for these unique instance that runs on the server RAC 1 node, can I use the RAC database listener that runs from the House of the grid or I have to create another auditor?

  Thank you in advance and also let me know if I can use DBCA or rconfig when the only instance and rac database are on separate nodes.

  K

  Fix. And that's what I would normally do. In general, I would have just an ORACLE_HOME directory that can be used by the punctual and RAC databases at the same time.

  See you soon,.

• Upgrade or install fresh to 11g RAC 10 GB Single Instance base data?

  What are the benefits of taking a server Oracle 10 g clone and carry it to the node two ORACLE RAC?
  
  I think I could do the following:
  1. install and configure Oracle Clusterware
  2. install and configure the software database only
  3. get a database of clone of 10 g (database file, init.ora, trace controlfile.
  4. apply the database 10 g of Clone on the Oracle RAC 11 g database waiting it to be accessible from both nodes
  
  
  The other Option
  1. install the Oracle 10 g database software in the new environment
  2. get a clone of 10 g production database and apply to the new development environment
  3. install the software of database 11 g only
  4. turn to level 10 g single instance of database 11 g single instance
  5. install and configure the cluster 11 g clusterware
  6 move the single instance of 11 g to 11 g RAC
  
  
  When it is maybe a good idea to add DSO for this implementation? Your ideas are appreciated.
  
  Thanks in advance!

  Hello
  If you have 3 business applications, so it is good to have 3 diff for all 3 applications services it will however help only if you have multi RAC node where you have the flexibility to define the services running on specific nodes so now two node RAC, it will not be very different.

  That your goal is both fault-tolerance, I suggest you create a service with a favorite and one available to get load balancing server side, select also load_balance = yes and failover_on on the entry of TNS to switch client-side client-side.

  I hope you know for failover, only queries select are get toggled if method = select. DML is not supported for failover and you have to manage with DML failover demand only.

  Please check my blog for more details on the RAC load balancing, failover and services below.

• convert CARS to single instance ebs R12

  Hi all
  
  I couldn't find any docs on metalink about converting R12 EBS of a RAC (2 nodes) to a single instance.
  If you know all the note please let know me.
  
  Thanks in advance.

  Hello

  Note: 406982.1 - cloning Oracle Applications V12 with quick Clone and
  Note: 559518.1 - cloning Oracle E-Business Suite Release 12 RAC systems compatible with the Rapid Clone

  can you tell that one to CARS to single instance using filesystem cook. ?

  As already said, there is no specific notes covering the cloning of the CARS with no CARS. Use the old note to clone non RAC with no CARS and the second to clone of CARS at the RAC.

• Make a cluster node off-line mantaining all opend session without TAF

  Hello
  
  I would like to know if in oracle 10g RAC, it is possible to make a sort of stop transaction on a single instance of it that moves end of sessions on one of the other RAC nodes. I know I could look on the docs for this, but I have not found an explanation of this particular case yet, and I have some doubts about the existence of such a method.
  
  But it will be very appreciated to explain.
  
  Thank you

  It will redistribute "idle" sessions among other nodes in the cluster?

  No, it's not really work of the Forum. This should be handled by the application. The instance disconnects the session, and the application should reconnect (and will be directed to the other instance).

• 10.2.0.4 patch on the database ensure single instance

  Hi all
  
  We have a production base 10.2.0.3 running with CARS having 2 nodes on Solaris 10. We have fixed this
  databases for 10.2.0.4 (two nodes) on production without any problem.
  
  We have a database of physical standby (10.2.0.3) with 2 nodes on solaris 10. But we stopped node2 sometimes
  back and currently is a database of pending of the single instance. New whe trying to apply the patch to frame watch
  It shows that the two nodes during installation and the installation fails when he tries to look for node2.
  
  What is the solution for this problem? Any document on how patch on the day before the only instance of database when
  the production runs in the CARS.

  I think you're basically saying that you have a 2 RAC cluster with node 1 down (possibly permanently) and you want to just patch 1 nodes?

  It's not too surprising the installer is by train to connect the other node when in your inventory is you have a 2 cluster nodes.

  Have you tried to run the installer with the option - local?

  This should just patch your local node. Of course the dictionary changes will be applied through MRP from the primary database.

• Cold migration of MSCS cluster node clients?

  Work on the establishment of a MSCS cluster on 2 hosts.  The hosts are the ESXi 5.5 build 1892794.

  My shared disks are RDM compatibility mode physical that I have attached to a second SCSI controller in physical sharing mode.

  My cluster validation wizard is successfully completed.

  However, if I turn off the guests, everyone migrate to a different host (with FC to the RDM LUN connectivity), turn on and then run the cluster validation Wizard error e/s disk wizard reports on tests of arbitration and failover.

  I learned that when I see these mistakes I can unsubscribe the VMs, detach the storage from the host, restart the host, attached storage, re - save virtual machines, and then validation is successful.  However, it is a bit complicated and if I say lose a blade and need to put one of my guests node elsewhere, I want to do without the time and hassle.  Is this possible?

  I know vMotion is not supported with the physical bus sharing, but this ban applies to cold (power off) so migration?  Or is this an indication that I screwed up my configuration?

  Any thoughts would be great.

  Thank you

  Here's what VMware has sent:

  =======================

  -A virtual machine that has a ROW in a MSCS cluster connected in physical compatibility mode cannot be vMotioned.

  -Even if you do a cold vMotion (stop the virtual computer, then vMotion), the ROW could be detected as vmdk and you may need to remove
  She and present it back or re - enter as you mentioned.

  -Best practices recommend Vmware are that - before the migration, remove the ROW of the virtual machine, and then migrate the virtual machine. Once the
  VM was vMotion, then you can attach the RDM to the virtual machine.

  Unfortunately there is no work around on this
  scenario.

  ======================================

  So I guess the cold, you can migrate the MSCS cluster nodes but sometimes it does not work quite as well and so its best to remove the ROW before migration cold.

  Thanks to all who have posted!

• Scan of single instance listener

  Hello
  in my cluster 6 11.2 knots, I have 1 single instance 11.2
  This instance uses the earpiece of IM and I can access by using the vip host.
  Using the scanner I ora-12514.
  
  Why?
  
  Thank you.

  Yes, you can attach an instance of a specific listener on a specific host by defininig remote_listener parameter. However, in a cluster of 6node, you cannot be sure that the listener ANALYSIS starts on the node that your database instance is running. I advise to use a listener dedicated for this instance.

• can we use Grid Infrastructure 11.2 to protect a single instance database?

  Hi all
  
  I would use Oracle Grid Infrastructure to protect a single instance database.
  I found these documents:
  http://www.Oracle.com/technetwork/products/Clusterware/overview/em-DB-failover-128585.PDF (for 10.2)
  http://www.Oracle.com/technetwork/products/Clusterware/overview/SI-DB-failover-11g-134623.PDF (by 11.1)
  
  I was unable to find a similar document for 11.2 GI. Do you know if such a document exists?
  
  At the moment I only know that the IM is free if used for Oracle products, but I'm not shure if it can be used for external applications one-time protext or databases

  Hello

  While it is still working (failover scripts you find in the demo folder $GI_HOME7/src/demo/coldfailover), the document does not exist, because with 11 GR 2, there is a solution to support called RAC ONE node, so make the manual configuration of obsolete.

• Start several Instances of ABC to a single Instance of the EBS provider

  Dears
  
  Currently an initiative of integration, we are integrating next design flow:
  
  (1) we have a single applicant request; We design the related ABC applicant
  (2) we use on single EBS. We use the EBS synchronization operation
  (3) we have 2 provider ABC
  
  Our business requirement is:
  If a single message is derived from the application of the applicant by the applicant, ABC, it must be published both applications via ABC provider provider components. In fact an instance of ABC single applicant will create, only one instance of the EBS and 2 provider ABC instance created
  
  Can you please suggest how we can design the EBS service in such a way that 2 instances of provider ABC will be created from single instance of EBS
  
  Thanks in advance

  The answer to your question is Yes, one Ombudsman can invoke two service calls at the same time as well.
  First of all, define your service references in the composite.xml
  Once you have done this, you can add any number of routing rules for each operation defined in the Ombudsman. In your case, you need to add two static routing rules within the same operation in the Ombudsman file. You can also select if the calls will be sequential or parallel by selecting the correct value in the drop down within the routing rule. Each routing rule will call a service reference in your case.

• DEV and quality assurance within the oracle single instance

  We have our DEV and QA in a single instance of oracle. Scripts that refer to table in DEV names will be copied on to QA DEV quality assurance tests for unit tests at the end. DEV, extract us data from 5 source systems, one for each State of the United States, which use the same application, so the names of the source tables are identical, and so in our staging area we have a scheme by the State such as TX, GA, MD and we extract data in tables that are identical to the staging tables. As cross us the aggregation state our scripts should refer to TX.employee and GA.employee in the same sql statement.
  
  What is the best design for this using SCHEMAS, DATABASES VIRTUAL PRIVATE, VIEWS, SYNONYMS etc.?
  
  
  
  
  
  Thank you in anticipation

  Just for my knowledge, if I found myself in this situation of VIRTUAL PRIVATE databases would make sense here?

  I guess that you could possibly use VPD. But it would create major problems if you have always wanted to make schema changes - you could not add a new column to a table in DEV, for example, without this column is also available in AQ. You could not have code in DEV that does not exist in QA. I guess you could really get fancy and use g 11 edition redefinition to have an edition of dev and qa edition but I wouldn't think how to promote prod code in this kind of environment. In addition, editions is a characteristic of the company (at least, I'm not sure if it is an extra cost option) which would tend to be beyond the solvency of the company trying to save on licensing costs by combining dev & qa in a single server non - VM (and even less in the same instance).

  You may have your application use any dynamic SQL so that dev could use the DEV_TX while QA scheme used the QA_TEX schema and it was only the schema of TX in prod, but that obviously never gets old very quickly. You can create a single set of synonyms the synonym TX_FOO points to DEV_TX. FOO for users of dev and TEST_TX. FOO for test users, but then you will have to remove qualifiers to schema of all your SQL queries.

  In short, an application like you describe trying to share an instance would be a pretty massive undertaking.
