  How can I add data file to an existing table on Oracle RAC ASM with no OMF? Thank you!

  Hello

  So I guess you have some files in ASM, see your first existing file structure

  Select file_name

  from dba_data_files;

  and to add to an existing table, the example below (even if you're better sticking with OMFs!)-is that what you are looking for?

  SQL > create tablespace TEST1

  Created tablespace.

• IOM 9.1.0.2 - Multi Weblogic JDBC for Oracle RAC Data Sources

  IOM-IOM 9.1.0.2 BP07 supports Weblogic JDBC Multi Data Sources (Services > JDBC > Multi Data Sources) for Oracle RAC instead of insert the "Oracle RAC JDBC URL" on xlDS and xlXADS JDBC Data Sources (Services > JDBC > Data Sources > xlDS | xlXADS > survey login > URL)?
  If so, are there any other changes that must be made on IOM, or simply to change data sources?

  Yes, it is supported. You install against a single instance directly of the Rac server. Then you update the file config.xml and jdbc resources in your server weblogic with the full address of rac. It is documented for installation against CARS. http://docs.Oracle.com/CD/E14049_01/doc.9101/e14047/database.htm#insertedID2

• Encryption and data interference

  We will have our colon examined for a compliance audit of the type PCI, and I have a question about the data file obfuscation and encryption. We have an oracle RAC, the two nodes running 10.2.0.2, and we don't use transparent encryption data. I was asked, and I could not answer, whether the data are hidden by another method. We use the DSO, and I can't find a way to browse the file system ASM to access files outside of the database. ASM offers any kind of compression or obfuscation that would make it difficult to read the files?
  
  You can even get to the data files in an ASM instance?
  
  Thanks in advance...
  
  Dan

  Hi Dan,.

  ASM does nothing but manage disks. Thus, the data files are not visible in a file system, it is true. But you can run ASMCMD and copy files on the file system. In addition, you can always run dd on raw devices themselves and access the data.

  ASM offers a very light, very low obfuscation, layer at best.

  If you want that data to be secure, you must implement the transparent data encryption.

  Hope that helps,

• Turning to Oracle RAC to the only Oracle database

  Hi all

  We are responsible for "make a copy" of Oracle RAC database a customer and our plan is to finish with the FCAC and allows you to host a new unique Oracle database. Very few of us familiar with CARS and looking for suggestions on how to do it (without affecting the source JAR).

  Can take a full expdb of the source database and simply use impdp to import into the standalone database server?

  Comments/suggestions appreciated.

  Thanks in advance.

  Can take a full expdb of the source database and simply use impdp to import into the standalone database server?

  It is an option. Data pump does not care if the source and/or destination is CARS or a mix. If the database is too large, it can take a lot of time to complete.

  Another option is to use the DOUBLE of RMAN feature. And another option is to restore the database from a backup.

  See you soon,.

• Oracle RAC (physically separate buildings)

  Hello

  I would like to know who already had this experience to prepare an Oracle RAC in separate buildings.

  We have two data centers, and we intend to prepare two separate nodes physically in this building (each node in one building).

  Data centers are in the same city.

  Could this be possible?

  Thank you!

  This looks like an extended cluster, alias "stretched CARS." It's a reasonably normal environment, although there are some considerations. You'll need storage on each side with ASM mirror and a third independent unit (a NFS server is good) for a copy of the file with the right to vote. A 10 GHz ethernet link should be more than enough. If you need assistance configuring her, let me know

• Issue of INS-35354 when installing Oracle RAC 12 on infrastructure Oracle Grid 12

  Hello

  I am trying to install Oracle RAC 12.1.0.2 one node installation on Windows Server R2 2012, but the installer told me:

  'Valid [INS-35354] the system on which you try to install Oracle RAC One doesn't not part of a cluster.'

  On the same server I have is installed and running Oracle Grid Infrastructure + ASM.

  I don't know what is missing the installation program, which is possible to register? The installation program does not provide which had not passed the specific audit.

  Thanks for the tips

  Georg

  

  

  

  Hello

  A CCR node does not mean that you install the grid infrastructure in a single node and install a base of a RAC data on this node.

  Basically, a concept CAR is similar to active passive clustering to provide high availability. To have a node database RAC upward and launched, you will have to install clusterware on at least two server by selecting the option during the installation of the IM.

  Pls follow the below post for detailed answer

  Someone at - he encounter the same problem with 12.1.0.2 by deploying the CDB for Grid Infrastructure Management repository? Is there something special with UEK3 (3.8.13 - 35.3.4.el7uek) on 7 OEL? Any necessary special kernel parameter (although the runInstaller controls do not mention)? I'm totally tapped by GI 12.1.0.2.

  Thank you.

  She was related to a memory on the provisioning of problem in the virtual environment as both nodes are VMs. Unfortunately none of these errors of memory were populated / pushed somehow in the virtual machine.

• Is it possible create Oracle RAC on NFS datastore?

  Hello

  Is it possible create Oracle RAC on NFS datastore?   With the VMFS data store, we use VMDK files as the Oracle RAC shared virtual disks with the Comptrollership and multi-writer SCSI Paravirtual, what about the NFS datastore? is the controller SCSI Paravirtual and writer multi function supported on the NFS datastore?

  Unless I'm missing something, this is not supported on NFS.

• Change password for an Oracle RAC installation account

  All,

  I'm not an Oracle DBA, but currently I am asked to fill in until a certified Oracle DBA lights.  I work with MS SQL Server and have servers managed for some time.

  That being said, my question is probably a simple.  In the Oracle 11 g RAC 2 installation guide, it tells you * must * use an account that exists on both servers to install.  So far, so good, we have a domain dedicated to this purpose and no other account.  However, due to a recent change in policy, we must also change the password on this account on a regular basis (annual).  My question is, which, if it is, a will this affect on our Oracle RAC database facilities?

  If we simply change the password at the domain level, rather than to check the "must change password at next login", is this cause problems with our data?

  My inclination is no, we have no problems, because current services 'running' Oracle use the local NETWORK SERVICE account that will not be changed, but confirmation of this would be appreciated.

  Environment:

  Operating system: Windows Server 2008 R2 SP2

  Oracle: 11.2.0.2 and 10.2.0.4

  GRID: 11.2.0.2

  Thank you

  Jason has.

  Change password of OS isn't a problem for Oracle DB.

• Oracle RAC 11 g fencing

  Hi all, I want to know if anyone knows the process of closing on the CARS, the other question is, Oracle RAC is able to restart the nodes (physical servers)?

  Thank you very much.

  Pablo

  The Oracle Clusterware is designed to perform a node eviction by removing one or more nodes in the cluster if a critical problem is detected.  A critical problem could be a node does not not by a heartbeat of network, a node does not by a heartbeat of disc, a machine hooked or severely degraded, deprivation of resources OS (IE high use of the processor, memory shortage/Swapping, queue/executed load medium high) or an ocssd.bin process hanging.

  For example,.

  Oracle Clusterware is based on the files of voting accessibility. If a node in the cluster cannot access the majority of the files of voting, the node (s) to which it applies is (are)

  immediately removed from the cluster (expelled / closed).

  This expulsion of node is intended to maintain the overall health of the cluster by removing members wrong (in other words, in order to avoid "split brain" situations, as well as data corruption).

  Note: From 11.2.0.2 RAC (or if you're on Exadata), expulsion of node may not actually reboot the machine.  It's what we call a restart without rebooting.  In this case, we reboot most of the clusterware battery to see if that solves the unhealthy node.

• FRA on NFS Oracle RAC one node

  rw,bg,hard,nointr,rsize=32768, wsize=32768,tcp,actimeo=0, vers=3,timeo=600
  

  For games of backups RMAN, copies images and Data Pump dump files, the "NOAC" mount option should not be specified - it's because RMAN and Data Pump do not check this option and specifying this can adversely affect performance.

  The following NFS options must be specified for 11.2.0.2 disc RMAN backup directory:

• Oracle RAC & BFILE

  Dear Experts,
  
  We have 4 nodes Oracle RAC 11gR2P-1 on RHEL 5.5 (64-bit). We want to store image on the database files using the BFILE data type. Its quite simple in a single instance database. However, how to achieve this in a 4-node configuration?
  
  (1) should we create a file system that is shared by all four nodes? or
  (2) create a file system access by a single node and make this node to write about setting type BFILE? How to get there?
  
  I don't want you guys wasting your valuable time to write the code here, but rather to share your idea on this.
  
  Enjoy any new idea as well.
