• Creation of the DB service in 3 node RAC

  IM and DB Version: 11.2.0.3
  
  We have a 3-node RAC. We have about 15 applications connecting to 25 different patterns in this PB. For each request, we create a DB CARS service. Should add US 2 instances as the privileged forum or 1 privileged forum and 2 instance available?
  That one is recommended
  

  srvctl add service -d ORCL -s GRN_SV -r ORCL1,ORCL2 -a ORCL3
  
  or
  
  srvctl add service -d ORCL -s GRN_SV -r ORCL1 -a ORCL2,ORCL3

  You guys add all other parameters (such as BASIC, PRECONNECT,.. .etc) for the creation of such services as mentioned in the documentation below?
  
  http://docs.Oracle.com/CD/E11882_01/RAC.112/e16795/srvctladmin.htm#i1008562

  Hello

  It depends on what you want to achieve.

  If a service is running on 2 instances (command 1), while already connections between customer first are spread across 2 instances.
  If a service runs only on a single instance (command2), then all connections of clients will be will to the same instance.

  If the instance 1 fails, then the scenario will take place as follows:

  1.) only 50% of users will recognize the failure and TAF will apply to 50% of the users. Users connected on 2 instance are not affected at all (almost... There may be an impact on the performance of small due to reconfiguration).
  2.) will affect all users. But TAF will switch to the new instance (which can be ORCL2 or ORCL3) of all sessions

• Oracle RAC and replacement of equipment

  Hello world

  next year our Oracle RAC (hardware) servers will be is more supported. We have a 2 node RAC (SE) running on Linux 5. For you, what is the strategy easier (and safer) to replace the equipment:

  • Reinstall complete with database exports / imports.
  • Adding new nodes to the cluster with new servers and delete 'old' (but it seems that the same version of operating system is required in accordance with the documentation).
  • Clone of the cluster according to the Oracle documentation on news servers.

  Thank you for all your ideas. I googled a bit, but I've not found much info.

  Carlos.

  • Adding new nodes to the cluster with new servers and delete 'old' (but it seems that the same version of operating system is required in accordance with the documentation).

  It's what I strive for. If your time with new nodes in the cluster is short (less than 24 hours), and you stay on the same distribution (i.e. OL5 to OL7), then several times, this isn't a problem. If you still have concerns and do not feel comfortable with this recommendation, then I'll recommend another avenue. I often used it when I was doing something similar for the production system was too critical to take no risk.

  1. Up new servers in a cluster. You can even start with the version of grid Infrastructure more later/more big who can save a future update maybe you.
     1. It will take a new OCR and voting disk new configuration.
  2. Attach the storage shared on the new cluster. For a short period of time, you will have storage mounted to both old and new.
  3. Install the RDBMS software on the new cluster. Wear on all the config files you might need more... tnsnames.ora, sqlnet.ora, etc..
  4. When you are ready to drop the database on the old cluster, cutting on the new cluster.
  5. Use "srvctl database add" to add the database to the new cluster.
  6. Use 'srvctl add instance' to add the instances to the new cluster.
  7. (Optional but normally a good idea), use 'srvctl add service' to add services to the new cluster.
     1. Steps 5 and 6 above usually use the same name of db, same instance names, same service name.
  8. You now have the database running on the new hardware. Stop the old servers

  The only other sticking point would be handling the SCAN and traditional VIP. When I made this drive, I usually my network guy change the SCAN VIP and traditional dignitaries to be alias in DNS that point to the new VIP.

  If you do your homework and have everything ready to go, the downtime can be less than 15 minutes for this approach.

  See you soon,.

• Connection speed slow on one node to a node RAC 2 put in place

  Hi all

  Having a little trouble with one of the nodes in a node 2 CARS set up
  We have sent traffic directly to the node in question (using a service that runs only on node 1)

  Forced connection to this node (sqlplus) since an application server remote takes 3 times as long does if we force fitting to the second node RAC.

  If I try to connect locally - connection speed is instantaneous-

  There is NO problem with the server performance

  There is NO problem with the perfromance instance / database - it is only noticed when the initial connection

  I've been in the network of the node and can see nothing wrong - so I was wondering if there was anything you guys might have experienced while the connection time is slow for a single node only (949 ms - compared to 247 ms on node 2)

  If anyone out there is interested or falls on this issue

  The problem has proved to be the mount point options MP Linux Volumes

  I had configured them as part of best practices for RAC / NetApp / Direct NFS - hjowever I also got the binaries for both nodes in order to have greater availability.

  Thereffore I would have had the Mount for NŒUD UNIQUE options.

  The change was to

  -stop the instance

  -unmoiunt binary files

  -change the following on fstab

            NFS rw, bg, hard, nointr, rsize is 32768, wsize = 32768, tcp, to = 3, timeo = 600, actimeo = 0 0 0

  TO

            NFS rw, bg, hard, rsize = 32768, wsize = 32768, to = 3, nointr, timeo is 600, tcp

  -start the instance and repeat on node 2

  #ASM instance on LAB4 via public IP

  + ASM1 =
  (DESCRIPTION =
  (ADDRESS =
  (PROTOCOL = TCP)
  (HOST = lab4)
  (PORT = 1521)
  )
  (CONNECT_DATA =
  (SERVICE_NAME = + ASM1)
  )
  )

  #ASM instance on LAB4 via VIP audience that is the old method of 10g to connect to a cluster

  + ASM1_VIP =
  (DESCRIPTION =
  (ADDRESS =
  (PROTOCOL = TCP)
  (HOST = lab4-vip)
  (PORT = 1521)
  )
  (CONNECT_DATA =
  (SERVICE_NAME = ASM)
  )
  )

  
  #ASM instance on Cluster via Public Cluster SCAN, i.e. the new 11g method to connect to a cluster

  + ASM_SCAN =
  (DESCRIPTION =

  (PROTOCOL = TCP)
  (HOST = cluster1-scan)
  (PORT = 1521)
  )
  (CONNECT_DATA =
  (SERVICE_NAME = ASM)
  )
  )

  The good thing is that a TNSPING to my client to all the 3 entries above, succeed

  Q1. Name of the Service don't know '+' i.e. that why for the + ASM1_VIP and _ASM_SCAN entry above, I could put neither ASM the SERVICE_NAME and not + ASM?

  Q2. I presume that for the method of 10g - the name of the Service be indeed ASM and not ASM1?

  Q3. If LAB4 should fail, my other node, LAB5, would inherit of the LAB4 VIP

  Thank you

  Jim

  Hi Jim,.

  SCAN is for the client computer access to the clusterdatabase without having to know which server in the cluster is to serve the db. SCAN is for your normal databases NOT the asm instance, your customers do not need to access.

  To connect to your instance asm on each node with sqlplus and get an output of:

  See listener parameter setting

  It will show, that asm has local defined listener and will register with the listener node running on your virtual IP address. It will not appear an entry for the remote listener.

  For your no - ASM databases, you will find set remote_listener parameter and pointing to SCAN listeners usually via an entry in the tnsnames like this file:

  MYDB =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = your-rac-scan-name)(PORT = XXXX))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = mydb)

  )

  )

  lsnrctl status

  -> you will get the output of the listener node

  lsnrctl status LISTENER_SCAN1

  -> you would give the output of the listener to scan if SCAN1 runs on the node of your ssh shell is sitting.

• 2 node RAC - administrator managed on the basis of ORpolicy-managedDatabase - what is the best

  We intend to build a GR 2 2 node RAC 11. I went through the documentation and found that datbase managed administrator is better when the number of nodes are very less.
  
  Need your input on what we are still in the design phase of the installation.

  Shashi,

  This all goes back to your goal. As you said, it's two RAC nodes and I assume that you will use this database cluster for a single application. If this is the case, then go with administrator managed the database because then you will have more control and be configured in less. Policy management is more useful when you implement a solution true grid where database is used as a service and multiple applications accessing data through services based on data provided within the system of large real application cluster. When I say database as a service, people may want to consolidate smaller databases in a RAC system to reduce costs and operational overhead while providing the same level of access to data for applications.

  So to answer your question, go with administrator managed RAC. I hope that I have you provided enough information for your decision :-)

• Routing connections via a single node in a cluster 2 node RAC

  Hello world
  
  My client has the following requirement: a RAC cluster active/active (for example/node1 node2), but with only one of the nodes being used (node1) and the other sitting there just in case.
  
  For things like services, I'm sure it's pretty simple - just have the value preferred on node1 and available on node 2.
  
  For connections, I guess I'd just the VIP in order in the file of tns, but with LOAD_BALANCING = OFF, so they go through tns entries in the order (ie the node 1 and node 2), then this would allow even the vip failover if node 1 is out of service.
  
  What sounds right? Did I miss something?

  Does not work on 10g - may not work on 11g. The listener can and don't transfer connections, according to what say the TNS connect string. If you do connect not via a SID entry but through a SERVICE entrance, and this service is available on several nodes, you can't (and won't often) be connected to instantiate on only one IP address that you have used in your connection to TNS.

  Basic example:

  // note that this TEST-RAC alias refers to a single specific IP of a cluster, and use
  // SERVICE_NAME as the request

  So we have connected to the node RAC 196.1.83.116 - and this listener we handed over to node RAC 196.1.83.127. The GR 11 2 earpiece seems to behave differently - it does not have a transfer of work (based on a quick test, I did on a RAC 11.2.0.1) in the above scenario.

  This question-how do you deal with just-in-case situation? How do you get the clients to connect to node 2 when node 1 is out of service? Do you rely on the virtual IP address of the node 1 be set on node 2? It's a safe and 100% guaranteed method?

  It may take a while (minutes, maybe more) for an address virtual IP switch to another node. Meanwhile, any client using this virtual IP address connection will fail. Is this acceptable?

  I don't know - I don't like this concept of your customer to treat the RAC nodes as a sort of database waiting for a situation of just-in-case . I don't see any logic in this approach.

• Stupid question: what is the difference between RAC and Clusterware?

  Hi all
  
  I'm about to start experimenting with the 11 G RAC Setup (to begin with, is that a cluster of a node, will try to add another later).
  
  I am reading the docs... I'm on that of clusterware installation, and it seems to indicate that the clusterware and RAC are two different things?
  
  http://download.Oracle.com/docs/CD/B28359_01/install.111/b28263/prelinux.htm#BABJHGBE
  
  With quotes like "UDP is the default for Oracle RAC interconnect protocol and TCP is the Protocol of interconnection for Oracle Clusterware. You must use a switch for interconnection. Oracle recommends using a dedicated switch. "
  
  Can someone tell me the difference? I know it sounds stupid, but it's confusing me, and I'm new on this.

  You can make your http://www.oracle.com/technology/products/database/clusterware/clusterware_for_unbreakable_linux_faq.html#7 understand

  What is the difference between the Oracle Clusterware and Oracle Real Application Clusters?

  In case of failure of the system, put in cluster guarantees availability high for users. Redundant hardware components, such as the additional nodes, interconnection, and discs, allow the cluster to provide high availability. These redundant hardware architecture avoid the single points of failure and provide exceptional resilience fault.

  In environments Oracle Real Application Clusters (RAC), Oracle Clusterware monitors and manages Real Application Cluster databases. When a node of the cluster is started, all instances, auditors and the services are started automatically. If an instance fails, the clusterware automatically restarts the instance, so that the service is often restored prior to the notice of the administrator, he was down. In this sense Oracle Clusterware is the base of Oracle Real Application Clusters.

  In these environments CCR ensures the continuous operation of the database, but also scalability by running several bases of instance data at the same time, usually one on each node in the cluster.

• the value node id and baud rate by lss (CANOpen)

For use in our network CAN I first set up the node id and the baudrate of each of them. The manufacturer told me to do it via the put layer Service (LSS). (How) I can do using Labview?

  I can use one of the following cards, NEITHER CAN: NI PCI-CAN/2 and NOR-PCI-8512.

  Thanks for the tips.

  Unfortunately, none of your interfaces are compatible with CANopen. You will need a PCI-8531.

  The flow rate in baud rate and node id can be configured easily with the library OR industrial for CANopen communication .

• Stop 1 node of a 2 node RAC how to move DB

  I need to stop a node of a 2 node 10g RAC for server patching.  All fine judgment, but the PB is still running on node 1.  When the server is stopped, it will move to node 2?  Is there a way to move to node 2?

  A "database" can never start. Revisit the terminology.

  An Oracle database is nothing more than all of the files on the disk. These files include data files, tempfiles, control files, online redo logs, file settings and if used, the password file. The database provides permanancy. That's what persists when the machines are turned off.

  The instance is the collection of memory and the processes that are running on the server. Process as PMON, SMON, etc and memory as the SGA and all its components.

  When you start something, you start the instance... or in the case of Oracle RAC, start multiple instances. You never start the database. The database is never running. Technically, users cannot connect to a database, they can only connect to an instance.

  Now to your question...

  Here is the result of my 2 node RAC cluster:

  ORA.resp.db

  ORA... se.type online

  ONLINE

  host01

  I have stop just one instance:

  [oracle@host01 bin] $ srvctl stop RESP d resp1 o-i immediate instance

  Now we see the result:

  So from the point of view of your original question... the database is now on the second node. To be precise, it is the _basededonnees resource_ in the sense of the OCR. All it means is that the resource database is available. Why it lists a specific host is beyond me because it comes to Oracle RAC and to be even more precise the database resource is available on all hosts that have instances that run on it for this database. Should be addressed on the State of the database for more information.

  [oracle@host01 bin] $ srvctl status database-d RESP

  Resp1 of the instance is not running on the node host01

  Resp2 of the instance is running on the node host02

  Resp3 of the instance is running on the node host03

  See... two instances on the other two hosts. The output of crs_stat could have easily showed the resource online on host03 as well.

  See you soon,.

• Disable the single node rac 11 GR 2

  Hello

  We have 2 node rac 11r2 aim to test how to disable a node oracle 11 g 2?

  Thank you

  Hello

  Still not very clear, but what I understand is -.

  "We have 2 node oracle rac 11rg r2 for the objective test when running on the database of the two node 1 & 2 we must restart the node 2nd server sometimes." What happens to the databases and cluster? "

  As you're running 2 bow TIE, if stop you the instance on node 2, db will still be available for access that users can connect to the instance on node 1 1. If take you down the instance and the cluster on node 2, node always 1 and 1 instance will be available to the user.

• How Oracle Clusterware Oracle RAC and 3rd-party Clustering with them

  I have some questions on how Oracle, Oracle RAC and 3^rd party clustering CLusterware fit between them.

  Q1. My understanding is that the Infrastructure Grid Oracle Clusterware is Oracle's Clustering solution that allows applications to cluster? that is, it is a general clusterware solution to compete with those already on the market. Is this correct?

  Q2. So why CARS is necessary for the Oracle cluster databases? An Oracle database is not just considered one application like any other? So why can not just use you GI / Clusterware to gather what you would do for any other application? Why so you need RAC to the Clusterware Summit?

  Q3. Is it is possible to combine an Oracle database using 3^rd party of clustering and not use Oracle Clusterware and CARS at all that is can you say cluster, an Oracle database using say Sun Clusters, Clustering AIX or Linux native same clustering?

  Q4. If the RAC is purely for Oracle Cluster databases - what is with the title "Real Application Clusters"? What's real on this subject?, what to ask?

  Q5. I also read that RAC can use 3^rd party of clustering. However if you decide that this is the case, then you need to install Oracle Clusterware when even (I think for interconnection must be created to allow the merger with Cache between Instances of node?).

  Is this the case?  If yes why never bore you with 3^rd party clusters? -Since you will have to install Oracle Clustering anyway - and I probably have to license (all I can think about is the scenario that you already have a cluster of 3^rd party in place and you decide that you need to use the same material for a database cluster)?

  All wisdom greatly appreciated,

  Jim

  Yes, with 10g, you had to use the CRS, and with 11g, to use the GI.  For 9i RAC, you would use Verits Cluster and Sun Cluster or anything else.

  11g RAC to GI.  As above, you can use clusterware extra if needed.  I gave the example above where to a 10g RAC we used the CRS to the cluster database/listener/vip and allowing groups of volume and filesystem in HACMP cluster.  File systems were not shared, but could switch to another node failure node, who has been treated by HACMP.  The volume of the groups containing the raw devices were shared volume groups.  For 11g, I never used extra clusterware on top of CRS and have always used ASM which is part of the GI.

  The application provider only certified database to run on 10g on AIX with raw devices.  What is strange about that?  It would be unusual that you probably expect to use ASM instead of raw devices, but it is what it is.

  See the following Note of Oracle for more information: using Oracle Clusterware with vendor Clusterware FAQ (Doc ID 332257.1)

  It is perhaps easier to explain if you can explain what problem you are trying to solve?

• RMAN backup and restore into Production KEEPS RAC and DATA

  Hi gurus of the Oracle
  
  We need the expert advice for tune and cross check the RMAN Script for Production environment below below
  
  Please suggest any corrections or comments on below mention scripts which will be executed on RAC and Production DATA GUARD environment
  
  LINUX RHEL 5.5 64-bit
  ORACLE GRID Infrastructure R2 Version 11.2.0.3.0 (we use ASM Cluster File system)
  ORACLE11g R2 Version 11.2.0.3.0
  
  We planned for basically rman backup drive using control file target instead of recovery catalog database
  
  We will have Data Guard Setup between 2 remote sites of database and two remote sites have running the local 2-node RAC database

  Thank you mseberg

  This command is the full backup or a backup of level 0?

  full backup as compressed backupset
  data include current controlfile more archivelog deletion entry;

  We use command below for the full backup of database.
  database backup incremental level 0 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL0_%D_%M_%Y'
  include current controlfile
  tag 'datafile_full ';

  We use the command below to the increment backup
  database backup incremental level 1 FORMAT ' / backup/RMAN_Backup/rman_bkp_%U_%d_%T_DATAFILE_LVL1_%D_%M_%Y'
  include current controlfile
  tag 'datafile_Incr ';

  What is the different when we use
  CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

  or

  full backup as backupset compressed database include controlfile current more archivelog delete all input;
