• Shoot down a node in the RAC Server

  Hi all
  
  Oracle 10.2.0
  Windows Server 2003.
  
  Can someone please advice how to bring down a node in the RAC Server?
  
  I need to lower it for maintenance. Meanwhile the other node will be available to users. There will be no downtime.
  
  And we also watch set up for the RAC server.
  
  Also should I stop the day before?
  
  Please advice...
  
  TIA,

  You must use Oracle provided srvctl to manage your RAC
  You must leave your server running waiting, because other nodes are still running.

  srvctl stop instance db_unique_name d-i inst_name_list

  Table E-29 srvctl stop instance Options

  Description of the option

  db_unique_name d

  Unique name for the database

  -i inst_name_list

  Comma-separated instance names

  stop_options o

  Options for the stop command (for example: normal, transactional, immediate, or give up)

  connect_str - c

  Connection string (default: / as sysdba)

  q

  Connection string for query from stdin

  Example of

  An example of this command is:

  srvctl stop instance crm d-i crm1

• Syntax of use YES to remove a node from the RAC

  Hello
  
  In reference to the Oracle documentation on the deletion of a node of RAC environment, it showed two syntaxes
  

  -- syntax one
  ./runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME "CLUSTER_NODES={rac2}" –local
  
  -- syntax two
  runInstaller -updateNodeList ORACLE_HOME=$ORACLE_HOME CLUSTER_NODES="" –local

  In one, he used CLUSTER_NODES = "' and the other 'CLUSTER_NODES = {rac2}'"
  
  They are both correct? Made the CLUSTER_NODES = "" means the current node is affected? "
  
  Thanks in advance.

  to remove a node, follow the steps

  1 remove ASM Instance
  srvctl stop asm - n
  srvctl remove asm - n
  RM - r $ORACLE__BASE/adfflin / + ASM
  RM - r $0RACLEJOME/dbs / * ASM *.

  Finally, delete all the entries in the/etc/oratab ASM. These entries have the prefix + ASM

  perform the backup of your rock when you have completed this
  operating mode.

  2 remove the listening process
  As the Oracle user, on any node in the cluster, run the netca

  On the Configuration page, select the Cluster configuration and click next to open the Active
  Nodes page.

  On the page of the active nodes, select the node that you want to remove and click next to display the home
  page.

  On the homepage, select listener configuration and click next to open the page of the listener.

  On the page of receiver, this time select Remove and click next to open the Select listening port page.

  On the Select listening port page, specify the listener to remove.

  The NETCA will stop the listener daemon and remove the content of $TNS_ADMIN/listener. ORA

  3 remove the software from Oracle database

  On the node that you remove, log in as user oracle and

  come on in ' cd $ORACLE_HOME/Yes/bin '.

  . / runlnstaller - updateNodeList ORACLE_HOME = $ORACLE_HOME CLUSTER_NODES = ""-local "

  Start the YES program and delete the Oracle Home
  CD $ORACLE_HQME/Yes/bin
  . / runlnstaller

  The YES homepage will be displayed again. Click on uninstall the products and inventory
  dialog box will be displayed.

• Error while executing script root.sh on the nodes at the RAC 11 g installation

  Hello friends,

  Here, I face an error while I run the root.sh script. During the installation of grid RAC, he asked a few dependencies of prereq. There are several .rpm files that were the prerequisites for this installation. I ignore them and I continued the installation. Now, he finally threw an error when running root.sh script. I tried to install several .rpms acquisition of information from the internet, but always this script does not work here.

  Please, suggest what should I do at this point.

  

  You guys could help me out here, how I need to go further.

  Simple google search will give you missing RPM. try to install and see if that solves the problem

• PIN dbms_cube.build jobs parallel to a specific node on the CARS

  Is it possible to Pin dbms_cube.build jobs parallel to a specific node on CARS. Currently, work with say parallelism of 10 bays on all nodes of the RAC.
  
  Is it possible to control for the jobs of the child works on the subset of nodes. Unable to see how we can link to categories of jobs and services with dbms_cube.build.
  
  Any suggestions will be much appreciated.

  JOB_CLASS was added in 11.2.0.2 precisely for this purpose. It is undocumented, because he missed the 11.2.0.1. Deadline for documentation, but it has exactly the same meaning as the job_class parameter in DBMS_SCHEDULER. CREATE_JOB.

• Want to migrate the database (4node RAC) size of 4 TB of 10.2.0.5 at 11.2.0.4 on the new servers where the new type servers Primary (4 nodes) and Eve (4 nodes).

  Want to migrate the database (4node RAC) 4 TB size of 10.2.0.5(8 rompt = 4 prim/4 veille) to 11.2.0.4 on the new servers where the new type servers Primary (4 nodes) and Eve (4 nodes).  So with minimum downtime I have restore and recover again on 11.2.0.4 server must then clone that to create the day before.   Here, my question is can I take 0 backupp level before hand and restore on target (new) then primary at the time to leave the downtime take backup of level 1 of 10g and then retrieve it on 11g (new server) after successful recovery I'll perform clone to form eve of database on the new server. does this strategy work? If it works, can someone suggest me steps how can I need recover with backup after restoring the backup of level 0 on 11g. Like should I upgrade before you retrieve it with level 1 backup or I can update and then recover with the level 1 backup from the old server to the new server.

  Here is former servers of RHEL 5 version and new servers are RHEL 6 release.

  1 backup L0

  2 restore L0

  3. L1 and ArchiveLogs database backup

  4. copy BackupPieces L1 and ArchiveLog BackupPieces on new server

  5 CATALOGUE START WITH... to catalog the BackupPieces

  6. TOGETHER until lastavailable SNA / Archivelog + 1

  7 RECOVER DATABASE (should automatically identify the L1s and to apply ArchiveLogs)

  8 STOP

  9 START UPGRADE

  10. run catupgrd.sql

  You should also take care on the locations of the data file, dump, instance settings destinations, all link database from the database, connectivity application etc.

• Telnet between the 2 nodes before installing RAC 11 GR 2

  Hi Oracle RAC guru,
  
  For the 2 nodes were installed RAC (GR 11, 2) clusterware, they need to be able to telnet each other with port open? and ping scan name must be successful before you install the clusterware software? operating system is Linux x86_64
  
  Thank you!
  
  SC

  Hello

  the VIP and the SCAN IPs aren't yet to the ping requests (let alone telnet).

  One of the main tasks of a cluster should provide these entry points. So they will be available as soon as your IM is running, but not before.

  Make a res stat crsctl - you on your clusters existing and you will see the VIP and VIP SCAN (online) resources. If they don't are not online no VIP don't will be 'plugged' on top of your network cards.
  You can also see the IP address with ifconfig-a on existing clusters. And you will see the difference on your cluster "clean".

• Configuration of the laptop for R12 with node 2 11g RAC database

  Hi all
  
  I plan to buy a new computer dell laptop XPS to install Oracle Apps R12 with node 2 11g RAC DB by creating virtual machines.
  
  Configuration:
  

  generation of Intel processor i5-2410 2 (2.3 GHz, core 2, 3 MB cache)
  8 GB RAM DDR3
  750 GB HARD drive

  this configuration will be sufficient for the highest installation? RAM? Processor?
  
  I've read a few threads over on this forum where people have recommended for installation of single application (11i or R12), this kind of configuration can be enough.
  
  Please answer.
  
  Thanks in advance.

  HARD DRIVE 750 GB

  This configuration will be sufficient for the highest installation? RAM? Processor?

  You need at least 4 GB for installation on a single node R12. So, if you plan to have 3 VMs (1 application node) and 2 RAC nodes or 4 virtual machines (2 application and 2 RAC nodes), then I suggest that you add more memory. However, your RAM should work, but don't expect (if you go with 3 VMs) but do not expect the performance to be perfect.

• Satellite A300 power suddenly goes out during the race for hours

  Dear users of the Forum,

  I am facing a strange problem in operation.
  My laptop Satellite A300 is suddenly down power during the race for hours.
  It is auto off not exactly. Not the way windows stop, is rather like strength to off (as when I press on & power button to stop force).

  This happens automatically, starting again, the screen saying "windows does not stop properly, start windows normally" is apperanig.

  I suspected virus infection, I tried full scan with nod 32, essential microsoft, kaspesky - 1 by 1 (previous uninstall and install the new), but all the antivirus intremediately scan stopped due to this power off.

  Watch movie also stopped in the Middle, attempted to convert the movie file format also was arrested several times because of this problem of automatic disconnection.

  I tried to run only on the power (remove battery) and got the same result.

  can anyone identify the problem? can you please give me the solution?

  Hello

  I put t think it is s virus.
  En me it looks like overheating. Eventually the high internal temperature requires the laptop to close. This is done automatically to prevent the equipment from damage
  I'm not quite sure what could cause this exactly, but in most cases the dust inside the fans affects cooling performance and lead to a temperature higher than m.

  Higher temperatures could affect the RAM modules too, and perhaps that is the reason why some applications don't work properly.

  What to say; try to clean the cooling fans using a jet of compressed air and check out how the laptop would proceed

• BECAUSE a node: when to stop through SQL * more...

  
  Hello

  I installed a CCR node for the first time and playing with it to get better knowledge. The underlying cluster has two nodes, call them the Node_A and node_b.

  The cluster database itself is called upon to DEVELOP, DEVELOP_1 instance is running on the node Node_A, instance DEVELOP_2 is supposed to work on node_b. The preferred node is

  NŒUD_A.

  When testing database online relcation everything works as expected: DEVELOP_1 instance Gets the stop on Node_A node - instance DEVELOP_2 is started on node_b.

  But what closing instance DEVELOP_1 on Node_A with SQL * more I was surprised of the result:

  -C' is not instance DEVELOP_2 which began on node_b - it was DEVELOP_1 for instance!  (Because of this my control sews has changed - but is not the issue of this discussion).

  Now my questions are:

  -is the clusterware responsible for the DEVELOP_1 instance on node_b startup behavior when I stop instance DEVELOP_1 down on Node_A via SQL * more?

  - and if this behavior is documented? I went through the RAC documentation node, but could not find something useful

  Any help will be appreciated.

  Hi Jan,

  Yes, its expected behavior in a node of the FCAC, please consult the document below.

• difference between SWEEPING earpiece and VIP at the RAC

  Hello
  
  The SCAN and VIP are used to balance the load only as I know.
  
  Is that there is no difference between these two?

  Hi Billy and all,

  I answer too late. Sorry for that. I'm still not clear picture on VP geeing

  YOU SAID

  "A virtual address is just that--virtual." There also exist on another node of the cluster, as his 'owner' node is not currently running. "So this node services this virtual IP address, until the owner can"reclaim"this virtual IP address.

  2 node RAC 10 g R2 (so no SCAN)

  Let's host 1: abc.lmn.com;

  1 host ip: I say 129.1.2.3; and vip 1 as abc.lmn - vip.com-> 129.1.2.4

  2 the host: efg:xyz.com

  with the IP 129.1.2.5 and vip 2 as efg.xyz - vip.com-> 129.1.2.6;

  The ip address and the VIp as just example only.i did not follow the standard conventions.

  Scenario: the client tried to connect to the instance and lets assume host 1 is out of service so host 1 (abc.lmn.com) cannot be used at the request of the customer.

  If the connection should switch to host 2. And host 1 cannot switch as its already down.

  VIP 1 is the address assigned to the physical host 1.

  MY Question is: as the physical host 1 itself is down how the 1 VIP which is attributed to host 1 helps the failover.

  I hope that your next reply will clarify my doubts.

  Thank you

  Just to give you clear answers:
  When host 1 goes down, his VIP are toggled on node 2. And when the client tries to connect to the VIP of node 1, it will immediately get the error message (it doen't wait on TCP/IP timeout) and then the client will connect to node 2 VIP.

  The reason why client does not connect to the VIP of node 1, however its PLACE on node 2, is because when VIP has switched to node 2, his questions, the new MAC addressed to customers. Client both get immediate notifications as error and the client, and then connect to node 2' VIP that runs on 2.

  Hope this helps
