• Oracle 10g RAC, add node - no jobs for the new server

  Dear all,
  
  We want to add a new node (say node5) to our current RAC 10 g 2 (on Solaris 5.9 operating system). While trying to set up ssh as detailed in the http://download-uk.oracle.com/docs/cd/B19306_01/install.102/b14205/presolar.htm#BABJBAEB documentation, I found that node5 is able to ssh to all other RAC nodes, but none of the existing nodes is able to ssh without password node5. Further investigation shows that node5 cannot do a ssh to himself without a password.
  
  Can you please help me to solve this problem.
  
  Thank you

  Another point was found:

  Check the permissions of directory on X11R6. They should be 700. Set them accordingly and try again.
  I had the problem without password ssh was not possible until this that/home/oracle has been set at 700.

  Also check your system log file (/ var/log/messages) to find errors SSH.

• Question about the new disk on the Satellite A100 (PSAA9)

  Hello!

  To extend time to work on the battery to make hard disk access faster and to extend the disk space, I upgrade my hard drive.
  I found this beautiful disc:

  Link:
  [http://www.seagate.com/ww/v/index.jsp?locale=en-US&name=Momentus_7200.2_SATA_3.0Gb/s_160-GB_Laptop_Hard_Drive&vgnextoid=546207c8108dd010Vgn VCM100000dd04090aRCRD & vgnextchannel = c021a47948a3d0 10VgnVCM100000dd04090aRCRD & reqPage = model]

  This hard drive is compatible with my Toshiba Satellite A series and you have a better solution please respone?

  Love, peace,
  Vasja.

  The HARD drive is very nice.
  The A100 PSAA9 series supports SATA 2.5 hard drives.
  The 160 GB should also be compatible because some units of the A100 series were already equipped with 160 GB hard drives.

  I think it s a HARD drive supported.

• Oracle 10g RAC - private interconnection on VLAN not routable private

  There is in our data center existing Oracle 10g RAC configured with VLAN private interconnection managed by a different group of DBA.
  
  We create a new, separate Oracle 10 g RAC environment to support our request.
  
  When we discussed with our data center people to set up a local VIRTUAL private network for our CARS of interconnection, they suggest to use the same VLAN used by the other Oracle RAC configurations existing private. In this case the IPs of interconnection will be on the same subnet as the other Oracle RAC configurations.
  
  For example, if
  RAC1 with 2 nodes use 192.168.1.1 and 192.168.1.2 in the VLAN_1 for the Interconect, they want us to use the same VLAN_1 with interconnecting IP 192.168.1.3 and 192.168.1.4 to our 2 node RAC.
  
  Share the same subnet on the same private VLAN for the interconnection of different configurations of RAC, supported?
  Which will cause a drop in performance? This means the IPs of a RAC interconnect configuration is to pings from other RAC configuration.
  
  Someone met with such purpose?
  
  Could not find any info on it on Metalink.
  
  Thank you

  Yes
  It is practically very doable... as you would have only 4 m/c in subnet ip... and it is much less than the public subnet that we should abstain from interconnection.

• Can a weird question we use Data Guard to apply the bidirectional log?

  Hi I have a question about Data Guard, can we use Data Guard to apply the bidirectional log? I mean keeping the two of them primary and standby to Active status (read write Mode).
  
  Maybe my question seems silly, but I just wanted to check on it.
  
  Thank you

  Laughing out loud

  That Golden Gate or water courses that will work in two ways. One or the other. Puts additional requirements on the hardware is the downside.

  Data Guard does not do that.

• Oracle 10g Rac (TAF)

  Hello
  I'm known for RAC env.
  How to implement TAF in oracle 10g RAC approx.

  Before you configure TAF, you should know about TAF

  If the instance fails, TAF allows applications to automatically reconnect to a different instance. The new connection will be identical to the original, but uncommitted, existing at the time of breaking transactions will be cancelled.

  TAF can be configured to perform two types of failover: session and selectwith the resumption of the session, any uncommitted transaction will be cancelled, and the session will be linked to another instance, with the resumption of the selection, uncommitted transactions will be cancelled, the second will be connected to another instance and any select statement that was running at the time of the breakup will be rerun by the sesion again using the same RCS and recoveries lines will be rejected upward until the original request has failed. The Select statement will continue return the remaining rows to the client.

  a TAF connection must be configured in the configuration file net tnsnames.oraOracle. In oracle 10.1 and higher, the DBCA services management page can generate appropriate TNS for the TAF entries.

  To configure the TAF, the TNS entry should include a FAILOVER mode clause that defines the properties of the recovery as follows,

  TYPE attribute defines the behavior as a result of a failure. Value: Session, select or none

  Attributes of the METHOD--> when connections are made to the failover. Value: base or preconnect

  ATTEMPTS--> number of times where a connection should be attempted before displaying an error.

  DELAY--> the time in seconds between each connection attempt.

• Question about the new Yoga 10 HD +.

  Hello

  A few questions about the new Yoga 10 HD + that I hope you can answer.

  I bought the former model, last year. Love the design and long battery life, but a few major questions made me return.

  • Somewhere that I've read that it can not read NTFS on USB so I guess that's the same thing with a NTFS formatted microSD card?
  • Can it read exFAT formatted microSD cards?
  • Anyone who has questions about the audio via bluetooth?
    (I know that BT is not exactly High End HiFi but the old 10 Yoga for some obscure reason - most likely a driver problem which nobody cared to fix - rang * very * worst with visibly distortion while both my phone and a Tablet noname cheap I have zero about fidelity - any of my devices bluetooth audio) I tried aptX or not)

  So to avoid buying it back it also I really I would like to see if I can get my questions answered before buy you.

  While I love the form factor and long term issues above are only two Mayor dealbreakers for me. Bad audio quality = no joy listen to spotify, local etc. MP3s. not of NTFS or exFAT = some great movies.

  My old noname android Tablet really could use an upgrade so I'm really curious it may be, or I should watch the competition and will be form factor and battery LIFE.

  Thanks in advance.

  EDIT:

  If it does not support NTFS or exFAT on microSD card have someone at - he tried ext3 or ext4?

  I mean with Linux Android root, it should be a no-brainer to support at least when it comes to royalties unlike NTFS or exFAT where it * might * have some trouble with Microsoft.

  I used a USB through a USB OTG cable. NTFS or exFAT have been recognized by the Tablet PC. FAT32 is seems to be the preference.

• RAC and Data Guard

  I just want to know if my main site's CAR and I want to set up a physical standby site using Data Guard; the backup site must be in configuration CARS as well, or can it be a stand alone configuration?

  Hey Buddy,

  I just want to know if my main site's CAR and I want to set up a physical standby site using Data Guard; > the backup site must be in configuration CARS as well or can it be a stand alone configuration?

  No, it is not mandatory. You can set up a watch using one instance and the database with the help of a RAC. as well as the opposite.

  For example, I've already migrated a RAC to a single instance, using stand-by. Rather than perform a failover, we performed a switchove, then the database primary was a single instance and the day before by a RAC database.

  It will be useful,

• Oracle 10g RAC on CF7

  Hello
  
  If someone has been able to get this config? I have 2 servers CF7 in a cluser, each are currently pointing to 2 different Oracle RAC servers, it's OK for the pseudo load balancing is not for failover.
  
  I noticed the new 3.5 DataDirect JDBC drivers
  ( http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=42dcb10a) seem to work with 10g RAC, but are not supported, but I'm not sure how to set up the drivers 'Other' as stated in the link, the instructions do not provide enough information.
  
  Has anyone got the job and could let me know what I need to enter in the config of pilots 'Other' to make it work?
  
  Thanks in advance,

  Excellent, does work.

  Many thanks qtpattuti.

  Please let me know what is the reason.

  I think if you created these disk groups using oraclesm (asmlib), then you need to configure
  asm_diskstring = "" / dev/oracleasm/discs / * ' init parameter, and then try again. " DBCA you can't see these candidate disks because the ASM instance cannot discover this, provide this (using asm_diskstring = "/ dev/oracleasm/discs / *") and try again

• Question on the available disk space on the Satellite Z930

  I'm new on this Yes, you can not shoot me down if this is a stupid question. I just bought a new ultrabook Z930. Storage space announced was 125 GB (drive C is only show 100 GB available). Only, I installed MS Office Standard 2007, Norton anti virus and printer drivers.

  However, I now only 65GB of disk space, and I do not think that these applications take 35 GB. I removed the shadow at all.
  Can someone give me some advice please?

  Unfortunately we can not see info exact drive HARD, but maybe you saw something wrong.
  Check please Disk management in the computer management options and you can see all the information base on the HARD disk and each partition of HARD drive.

  I can imagine that this 35 GB is total data backed up on some partition that contains the operating system and all the stuff pre-installed.

• questions about the new SSD T530 upgrade

  I just bought a T530 that comes with a 500 GB 7200 RPM HARD drive. I bought a 256 GB Samsung SSD 830 and was trying to install this. The questions I have are:

  1. is it recommended I the SSD drive in the ultrabay housing and keep the HARD disk where it is? Or place the HARD drive in the ultrabay slot and have the SSD to the standard housing?

  2. is there a certain adapter that should be used on the installation of SSD or HARD drive in the ultrabay slot?

  3 are there settings that need to be changed when using an SSD?

  Thanks in advance.

  1. no difference whatever he is, although if you count hotswap in an optical device, it would be easier to have your primary OS drive.

  2. any generic SATA-UltraBay adapter should work. Make sure you have the size and the generation correct however.

  3. There are a few adjustments on swap files, defragment, etc. You should be able to find this information on the internet.

• EM12c, improvement of the system of two - Question about the new repository

  Hi DBA:
  I used the method of two system to upgrade my 11.1 SGD to 12.1.0.2. The upgrade has completed, and is followed by 7 of 42 officers, so I'm still trying to switch these. In the new EM12c, 'Management and Repository Services' page shows the connection descriptor - but it refers to the repository 11.1 SGD database. I'm afraid to ask, but if this should not be the new repository of WHO, that I created as a clone of the repository 11.1 SGD database? I checked my YES screenshot and the node logs; database connection details are accurate to the new database and the old repository. There is no glaring errors of the console EM12c. How do I validate this?
  
  Thank you
  
  Laura Sallwasser

  Hi Laura, support will update your SR with the solution and the first cause. To update this thread, the problem is that you had an agent (10.2.0.5 or 11g) in the box of SGD 12 c before the upgrade. SGD 12 c install also installs an agent on this box, but will not create the target host as target host was already created and controlled by the former agent.
  Travel to an agent will fail if the agent does not monitor the target host. Thus, oracle_emrep target relocation failed and raises questions that customers report.

  We donnt 2-system of support upgarde on the same host (guide says the same thing). Support will help you how to go forward, I explained the steps.
  I connected a bug to see if we can launch a warning in pre-upgarde console earlier.

• Oracle 10g RAC and Unix * question rlogin *.

  I supports several bases RAC 10 g running on servers pSeries IBM using AIX 5.3. Our data base and the clusterware indicated 10.2.0.3 10.2.0.4.
  
  I understand that user equivalence and rsh/ssh must be enabled so that the environment RAC and clusterware to connect across all the cluster nodes.
  
  My problem is an issue raised by our internal system Auditors. Are asking that the commands rlogin and exec for AIX is disabled, because they feel that it is a security risk. Two orders prompt for a valid user name and password when they are used for the remote connection or execute a command.
  
  I looked at the RAC documentation search online and Metalink (I'm not an expert on Metalink, though!) as well as Google and could not find anything indicating that rlogin and exec are specifically required for CARS work properly.
  
  Can anyone offer advice or their point of view on whether or not these two commands should be enabled for RAC in order to function?
  
  I thank you in advance for any help, you can give it to me.
  
  Kind regards
  Mark

  Hi Mark,

  as far as my knowledge goes CARS use neither commands rlogin or exec.
  After the installation of the cluster Oracle simply communicates via. (Clusterware) TCP and UDP (RAC) and is only sending and receiving messages. It is not necessary at run time for a remote access connection.

  ALS if ssh and rsh are solemnly used for installation and connection (not for communication).
  Oracle recommends always to leave active because it makes life easier to activate ssh every time that a patch is necessary.
