• On RAC primary DB and a single Instance as physical Standby...

  It's my 11g Data Guard scenario:
  
  BECAUSE primary database 11g.
  
  Single Instance Oracle 11g.
  
  My first question is:
  
  If each node of the RAC has 3 online redo log, should I create 4 or 7 journal watch over the database pending?
  
  If restore database Standby long after the day I do full backup and I've got ti registry manually archived newspapers, what I do for a node of the RAC archived logs of the two?
  
  Thank you very much.

  In form 7
  You must register for both nodes. Remember that you have a LGWR instance, so a redolog thread instance and the two wires together are all changes to the database.
  Please make sure that in this configuration of the archived redo logs are on a shared disk.

  Hello

  Haven't you designate all these documents, only to those that are applicable.

  For RAC to cloning no CARS, please see (Note: 783188,1 - certified CARS for the E-Business Suite cloning scenarios). If you don't have a CAR on the source/target nodes, you don't need this document.

  There is something more that you can refer to see (R12 Data Guard with database 11g)--(Note: 1070033.1-Business Continuity for Oracle E-Business communiqué 12 utilisant Oracle 11g Physical Standby Database) for more details.

• instance unique manual standby for a three-node RAC database

  Hi all
  
  I wonder how it is possible to create a database of manual standby for a primary database of the cars.
  Version Oracle's standard edition 11.1.
  I have experience of creation and manual management waiting for the single instance of database; I wonder if and how I can load the database one-time Eve to discover and apply the three sons to redo that I copy from the main site to the backup site.
  
  Can I use rman to catalog all the newspapers archived on the backup site?
  Configure several LOG_ARCHIVE_DEST_n settings to point to the many different path, one for each primary instance (one for each redo thread) and let rman automagically discover all logs archived?
  Do I only configure LOG_ARCHIVE_DEST_1, put archivelogs of all threads in the same folder and let the rman automagically discover all logs archived?
  
  Thanks for any answer!
  
  Andrea

  Hello

  Indeed, I added the newspaper archive transferred before the recovery process.

  During testing, I think (iirc) I have been unable to recover from the archivelogs transferred without catalog them all first. But this statement is out of my mind, I'm not 100% sure to do this, sorry.

  More details.

  Because it is a standard edition, I have to use on the side of the RAC ASM. So our normal scripts to transfer the day before primary archivelogs are obsolete.
  So I decided to put the thing all odds in the database. The primary database now uses the external Scheduler tasks to do the job. The side watch does not use ASM, so there is no need to maintain the logs in any special way.

  The steps are:

  1. get CNS primary and backup
  2 transfer the logs to the ASM gap on "normal" filesystem
  3. transfer (and compress, if not LAN) to watch archive dest
  4 catalogue side sleep
  5 back side sleep
  6 remove the normal file system (on both sides, but waiting in 2 days just to be sure)

  The steps on the side of the watch are both using the primary RCS of step 1 as a parameter to avoid error messages for the catalog or retrieve the call.

• Primary database is RAC and physical intelligence is the single instance

  Hi all
  
  I use Oracle RAC 11.2.0.3 as primary database, we will begin to use the Oracle Data Guard.
  I am designing my infrastructure and planing to use single instance Oracle 11.2.0.3 my stand physical database.
  
  My question is it possible to have my sleep as single instance database while the primary is RAC?
  is it possible to build my Oracle database single instance ensures from the primary database to the RAC, RMAN backup?
  Are there restrictions (or all of the points to consider) as my primary database is CARS while the physics of Eve is the only Oracle instance?
  
  in the link below
  [http://docs.oracle.com/cd/B28359_01/server.111/b28294/concepts.htm#i1039416]
  It was mentioned that primary can be CARS or simple and even the day before, but my question is possible to have primary as CARS all on standby as single instance? or it should be like each other?
  

  The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database.
  Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.

  Kind regards

• 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,.

• Convert a single instance of Rac

  Hello experts, I have already configured a database cluster between two nodes with a RAC database named cars. I also have a database to single instance named people in the first of the nodes. Now I need to convert this single (Persons) instance in a Rac database, I want to have two database RAC (cars and the new people).
  
  Thank you much in advance.

  Oracle provides following methods to convert a single at the RAC instance database:

• 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.

• Protect the single instance Oracle 11 g 2 with Clusterware linux No 11 GR 2 RAC

  Hi all
  
  I saw this link, but he mentions CARS as a solution:
  
  Use of Oracle Clusterware to protect a single Instance Oracle Database 11g
  
  I have seen various articles on protection one instance with cold recovery using clusterware, but they mention the scripts and the old versions of Clusterware. I'm trying to figure if possible to incorporate the virtual IP / scanning of listeners or if it is still a supported configuration...
  
  
  
  I implemented the 11 GR 2 using OCFS2 clusterware. Basically I just want cold failover from one node to another, and I don't want to buy a CAR license...
  
  Thank you very much
  
  Published by: vcovco on Sep 30, 2010 13:52

  Hi Vcovco,

  You must understand, that a VIP (host) works correctly for Oracle in conjunction with a listener to listen on the virtual IP address.
  Now, if a VIP (host) fails over to another node, the local listener won't. So even if you can ping the VIP no client can make connections. This VIP, since there is no listener listening on this VIP on the foreign host. (But the client will get a denunciation pronto to browse more through his address list).
  However, SCAN VIPs work differently, because they have an earpiece connected to them, which will also fail over to another node. This is why permits be accepted, if current running on the other node (as the listener moves with the SWEEP VIP).

  That is why in the past, you had to create a VIP 'user' and a 'user' listener, that there will be a changeover of the two (not like the Oracle of VIP welcome). A VIP SCAN done exactly that, it is not necessary for a 'user' VIP and the listener (However it still work!).

  a.) every DBA should make backups using RMAN in the meantime...
  (b) there is also a copy of asmcd command

  With regard to the advantages over OCFS2
  -best performance (almost RAW)
  -easier to extend (no need to resize)
  -no hot spots if storage is extended, because storage is automatically rebalanced.
  See here: http://www.oracle.com/technetwork/database/asm/db-tuning-guesswork-173710.pdf
  -consolidation easier
  To name a few.

  Another thing no one mentions:
  With OCFS2, you have a second clusterware running on the server. OCFS2 has its own mechanism of fencing.
  We must therefore consider some things more 'correlate' fencing OCFS2 and fencing OCW. Not that differently, they decide on what node restart.

  So my advice is: keep it simple. Use only the 1 clusterware.

  And last but not least: ASM now has a system of files ACFS

• 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

• 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.

• How to implement a stack of screen "single instance".

  I'm looking to implement an application that accepts only a single instance of specific screens.  What is the best way to achieve this?  I have checked the documentation and can't seem to find anything that addresses this issue.

  The idea is similar to a singleton pattern...

  If (screen is nothing)

  {

  screen = new XYZScreen ();

  }

  return to display;

  If I already pushed my XYZScreen in the stack, using the pushScreen() method, I would like to get a handle to that instance, and they have to protest against the creation of another instance and add it also.  Also the memory problem, it makes more sense for the particular project that we are working on.

  I can't seem to find anything like "UiApplication.getUiApplication.getScreen ()" to get a reference to a particular screen already on the stack, or a 'Stack.moveScreenToTop () '.

  Suggestions, examples or links would be appreciated.

  You can use getActiveScreen() and getScreenBelow() in a loop to see if your display is already present in the stack to display.  If this is the case, then pop, and you then press it to remove it from its current position and make it visible.  If it is not on the stack, you can just push it.

  It works for you?
