• 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

  Yes, its recommended configuration hangcheck timer at RAC

  Configure the Hangcheck timer

  The timer to check block is loaded into the Linux kernel and checks if the system crashes. It than the timer and check the timer after a certain period of time. There is a configurable threshold to hang - to ensure that, if exceeded will restart the machine. The hangcheck-timer module is not required for the operation of Oracle Clusterware (Cluster Manager), it is highly recommended by Oracle.

  modprobe hangcheck-timer hangcheck_tick = 1 hangcheck_margin = 10 hangcheck_reboot = 1

  Using RAW could be the problem. I'm not sure someone who has used Virtual Box with raw disks for their RAC testbed. Most people use ASM. I've seen a few people use NFS as well. You'll also want to stay away raw because that which is frowned upon in 11.2. See http://docs.oracle.com/cd/E11882_01/install.112/e41962/whatsnew.htm#RILIN931

  Under the Options deprecated for Oracle RAC 11 g Release 2:

  "Installation of files on raw devices is no longer an option available during installation. You must use a shared file system, or using Oracle Automatic Storage Management. »

• How to change NAME and intellectual property after installation of RAC.

  Hi friends,
  
  I have here a challenge... If you'd be grateful if someone can help me...
  
  I have to install Oracle RAC 10.2.0.3 on windows 2003 server 64-bit.
  
  My problem now is the server names and ips are defined and I'll install the RAC.
  
  But the need of the customer is that after a month, they need to change the names and the IP addresses of the servers (a time change).
  
  Because according to their Server naming standards, the current production servers have the accepted names and ips.
  
  Installation was on a BONE, 32 bits while they are facing errors of process memory. That's why they're going OS 64-bit on the new servers.
  
  After that the new servers are ready, data will be migrated to the new server. After a month, they need to change the names of the new servers for the old servers (current production).
  
  Could someone help me by giving me information on how to change the NAME and the IP after a RAC installation?
  
  No matter what metalink note or orders because it is...
  
  Thank you
  Mahesh.

  Hello Manu,

  In this case, you must reinstall the CRS again.

• Installation Oracle Linux 6 - won't be after this screen

  

  When I install until this screen, it will not proceed... How to solve?

  Hi GheeSeongand welcome to the VMware communities!

  I guess that the scroll bar does not reveal any button 'Next' at the bottom of the screen...

  You've hit a bug in Oracle Linux 6.2.  We have an article in the Knowledge Base describing the related issues during installation Oracle Linux 6.2 on vSphere and another related issue when you use virtual EFI firmware.  All these problems are caused by the same bug Oracle Linux (and they have released an update to fix it), but it seems that we have not yet a section in Knowledge Base describing the problem encountered on VMware Workstation, where the symptom is that the screen is cut off and there is no button 'Next' to visible.  (Interestingly, you can still use the keyboard to go through Setup... Press Alt + N)

  To get the display work correctly, try this:

  • Shut down the virtual computer.
  • Go into the settings of the virtual machine and configure the virtual machine display to have a screen at 1024 x 768.  Save the settings.  (I have been informed that sometimes this setting doesn't "stick", then you will want to return to settings and check that it is correct before continuing.)
  • Turn on the virtual machine and enter the Setup program.  You should now have a button "next".
  • Install Oracle Linux 6.2.
  • Once the client is installed, follow the instructions in the Knowledge Base article to install the update within the guest to correct the cuase of the root of the problem.
  • When you have installed the update and turn off your virtual machine, you can remove the limitation of 1024 x 768 display that you added earlier.

  Your Oracle Linux VM should then work correctly.

  Please let us know if this solves the problem for you!

  Thank you

• Oracle RAC 12.1.0.2 (GI battery) deployment on OEL 7 (3.8.13 - 35.3.4.el7uek) fails with ORA-27102

  Check if service NFSLOCK works... and if not start it.

  Mounting for Oracle data files options

  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:

  opts="-fstype=nfs,rsize=65536,wsize=65536,hard,actime=0,intr,nodev,nosuid"

  Thank you

  Pavang is right.

  I opened a SR and Oracle Support they confirmed she RHEL 5.5 with RHEL kernel is supported (minimal support). but Oracle is highly recommend to deploy the nucleus of the unbreakable Company Oracle.

  Some reasons for their recommendations:
  http://public-yum.Oracle.com/
  The core Oracle Unbreakable Enterprise for Linux is the standard kernel used with Oracle products. The build
  and QA Oracle database systems and other Oracle products use the core of Oracle Unbreakable company
  for Linux exclusively. The core Oracle Unbreakable Enterprise for Linux is also the kernel used in Oracle
  Exadata and Oracle Exalogic systems. Oracle Unbreakable Enterprise Kernel for Linux is used in all benchmarks
  tests on Linux in which Oracle participates, as well as in the setup of valid Oracle for x 86-64.

• IOM on Oracle RAC

  Because IOM installer does not support the Oracle RAC, Oracle asked that provide us with information for a single instance of DB of the CARS.
  
  Must this DB be prepared for IOM install in the same way as a stand-alone instance - using prepare_xl_db.sh (on linux)? And satisfy the requirements such as query_rewrite activated, etc?
  
  Thank you.

  IOM does not RAC support at installation time. After installation, you can reconfigure IOM to use RAC

  Use the prepare_xl_db.sh against any node of your RAC instance to create the schema.

  Installation provides one of the RAC instances as database.

  Once the installation is complete, reconfigure the xlconfig.xml and data sources in your application server to use URLS to active RAC database.

  hope this helps
