hi
IMO, your /etc/hosts should contain scan entry because it cannot be resolved here.
BTW, /etc/hosts should be identical on all nodes.
See my production settings (my PLWRS-GS-SCAN is registeres in RR way in corporation DNS and resolves to 3 IP's):
# Public
10.154.18.123 plwrs-db1.emea.nsn-net.net     plwrs-db1 db1

#10.154.18.120 PLWRS-GS-SCAN.emea.nsn-net.net     PLWRS-GS-SCAN
If you don't use DNS server, or for testing purposes, set one SCAN entry only in hosts file , e.g.:
10.154.18.118 PLWRS-GS-SCAN.emea.nsn-net.net     PLWRS-GS-SCAN

How to install GCC and DKMS on Oracle Linux?

Hello,
I am a newbie to Oracle Linux. I installed Oracle Linux on a virtual machine using Oracle VirtualBox. Now I need to install the packages DKMS and GCC in order to share drives between the host and the ghost.
Here is what is happening:
# yum install dkms
Setting up Install Process
Setting up repositories
No Repositories Available to Set Up
Reading repository metadata in from local files
Parsing paskage install arguments
No Match for afgument: dkms
Nothing to do
Please, advice what to do.
Thanks in advance.

Here is what you need to install under Oracle Linux or Red Hat Enterprise Linux to install the VirtualBox Guest Additions:
<pre>yum -y install gcc kernel-uek-devel-$(uname -r)</pre>
The packages are available from the Oracle public yum repository as already mentioned, or on the installation DVD in the server directory.

Problems installing OEM Cloud control 12c in Oracle Linux 6.X

Hi
I'm triying to install Oracle Enterprise Manager Cloud 12c in a Oracle Linux 6.4
Looking at the installation documentation in in http://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_packages.htm#CHDEJAFA it sys that I need the packages :
glibc-devel-2.5-49-i686 (This is a 32-bit package)
glibc-devel-2.5-49-x86_64 (This is a 64-bit package)
But I cant find them in the yum repositories.
If I query to my linux wihch version of glibc-devel are installed the output is
[root@emc tmp]# rpm -qa |grep glibc-devel
glibc-devel-2.12-1.107.el6.x86_64
And if i try to install it i receive an error compiling ins_sqlplus.mk due to ld because it can't find crt1.o
Can anybody help me?
thanks

What is the version of EM that you are trying to Install? Is it 12.1.0.1 EM ?
a) If this is em 12.1.0.1 then its a know issues to us which is fixed in next release ( you can refer bug:13833746 from MOS or open an SR to get more detail on this bug)
Run this below to make usre you have the packages.
# rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n" | grep glibc-dev
glibc-devel-2.12-1.80.el6(i686)
glibc-devel-2.12-1.80.el6(x86_64)
Checking the pre-requisites step fails as it is looking for i386 instead of i686. (On OEL6, prefix i686 denotes the 32 bit package - and not i386). If the 32 bit and 64 bit glibc-devel packages are present on the system ( check it manually) this Warning can be safely Ignored. Continue with the installation. If you are not sure, pls log an SR with Oracle support and they will help you. Donot ignore the warning in case of any doubts, work with support to get it solved. If you ignore the warning and packages are not on the host then you will get linking error during the install.
b) If this is em 12.1.0.2, pls log an SR and send me the SR number.

Configuring networking for 11Gr2 RAC

Hi - I have a couple of questions regarding networking and RAC install.
Please could someone clarify what the Virtual IP requirement is for a RAC node, and how one would actually set this up on OEL5 using a DNS server.
All input appreciated - thx

Hi,
I have a couple of questions regarding networking and RAC install.
Please could someone clarify what the Virtual IP requirement is for a RAC node, and how one would actually set this up on OEL5 using a DNS server.You will need the concept before attempting to install because it is not possible to explain the concept of Oracle Clusterware Network (VIP/SCAN) with a few lines.

Asmlib and oracleasm permission question for 11gr2 RAC install

Dear All,
I am trying to install 11G RAC on 2 oracle linux 6 machines (it is 2 virtual machines but I hope the principle applied).
I use asmlib package to create sharable disk.
I encounter a lot of user/group permission issue, so I decide to use oracle:oinstall to install my grid software.
Here are my questions:
1. when run oracleasm configuration -iDefault user to own the driver interface []: oracle
Default group to own the driver interface []: dba <<<<<<<<<< what group should I use? I see people use oinstall, dba...
2. after mounting /dev/oracleasm directory by using /usr/sbin/oracleasm init, what directory permission should I set?
it is root:root after mount.
I tried to run installer for grid, if I don't change /dev/oracleasm to 766, the ASM disks don't even show up.
Any suggestions?

If you are using single user for grid and database I would set oinstall as the group owner.
You don't need to set permission on /dev/oracleasm.. asmlib will take care of it
Have a read http://docs.oracle.com/cd/E11882_01/install.112/e22489/storage.htm#CDECEBGH for more information.
Hope it helps
Cheers

How to migrate data from oracle 9i database to new machine 11gr2 RAC ASM

Hi Expert
I need your expertise to advise me what is the best method to move data from oracle 9i database to new machine running oracle 11r2 RAC database with ASM.
Currently my production server running on HPUX ORACLE 9I database with normal file system. My new server is running SUN SOLARIS SPACR 64 bit ORACLE 11gr2 RAC with ASM. What is best method to move data over so it will be consistent. Any guide can refer.
Regard
William

Hi William,
See the note in metalink Migration of Oracle Database Instances Across OS Platforms [ID 733205.1] to saw the Endian Format of your OS. If is the same you can use the RMAN to convert the database to another OS, if not the only option is using export/import (Transportable Tablespaces).
To upgrade from 9i to 11g, see the note 837570.1 - Complete Checklist for Manual Upgrades to 11gR2.
To migrate your FS to ASM the only way is using RMAN, so see the note - How to move a datafile from a file system to ASM [ID 390274.1].
Hope this help you.
Best Regards,
Ruben Morais

[SOLVED]Problems when installing - DHCP and Pacman

Hello Arch Linux Forums,
I'm kind of new here and I'm switching from Debian, so excuse me if this question is noobish.
I've been trying to install Arch Linux for three days now, and the installation always screws up at either Select Source, Select Packages or Install Packages. It changes every time I try.
On Select Source - Failed to run dhcpcd. Check /dev/tty7 for errors.
On Select Packages - Pacman preparation failed! Check /dev/tty7 for errors.
On Install Packages - Installs a few packages, and then after a few packages download I get "No address record" on everything else.
Can someone point me in the right direction on what to do?
Thanks in advance.
EDIT: I tried to install today, worked fine. Did nothing different. Thanks anyway guys!

I tried the installation again and it failed at install packages. Here's the only line in /dev/tty7 that I think is related to it.
[DEBUG_UI] Package installation failed, check below for errors
I don't have it on right now, but it said something to that effect. It says that on the installer as well, although the only other thing it gives is the No address record error mentioned in the OP.

Swap size and / space from Oracle Linux VM Template

Hi,
I created few VMs with OVM_OL5U8_x86_64_PVM.ova.
However, root file system is 10GB and swap is 2GB even I created 50GB virtual disk for VM system.
I can't change these fixed size.
Can I increase this from template?
I create additional virtual disk and add to VM to use bigger swap(using OS command) but just want to implement default system virtual disk provides bigger than 10GB root filesystem and bigger swap size.
Thanks,
Jason

I tried exactly same with another disk but got same error please find the screen shots.

Windows 2008 DNS & DHCP configuration steps for 11gR2 GI install with GNS

Hi,
I have windows 2008 R2 server with DNS & DHCP services installed. I am planning to install 2 node RAC with GNS option.
The problem is i could not find any document to setup the windows 2008 DNS server for the below steps.
a. Configure GNS VIP : add a name resolution entry in a DNS for the GNS virtual IP address in the forward Lookup file.
gns-server IN A <virtual_IP>
where gns-server is the GNS virtual IP address given during grid installation.
b. Configure the GNS sub-domain delegation: add an entry in the DNS to establish DNS Lookup that directs the DNS resolution of a GNS subdomain to the cluster.
clusterdomain.example.com. NS gns-server.example.com.
where clusterdomain.example.com is the GNS subdomain (provided during grid installation) that you
delegate and gns-server.clustername.com resolves to GNS virtual IP address.
I am aware that this configuration steps has to be taken care by the System administrator. Here is what he tried and the results.
My SA was able to Configure GNS VIP in the DNS and the Nslookup works fine for this.
When he Configures the GNS sub-domain delegation the nslookup fails when trying to resolve the SCAN name.
Any step by step tutorial for this windows 2008 DNS & DHCP configuration for Oracle GNS setup would be highly appreciated.
Thanks,
Ashok Kumar.G

Oracle 11gR2 RAC installation with DNS

Dear Guru's,
I want to configure RAC on two node cluster with DNS(For SCAN) in my testing server.
O.S: RHEL5.4(64 bit)
Oracle Version: 11gR2(11.2.0.2)
Note: Am creating nodes in VMware ESXi server.
Just I want to know whether DNS should be configure in any one of those NODES or in separate machine.
Bala :)

Hi Bala,
I want to configure my Database with & without DNS. (Will try both installation in different servers)I think, you have already received a link on very good article about Oracle RAC installation without DNS and DHCP (I mean Jeffrey Hunter's article).
There is one more about Oracle RAC installation with DNS and DHCP (http://gjilevski.com/2011/10/05/build-two-node-oracle-rac-11gr2-11-2-0-3-with-gns-dns-dhcp-and-haip/).
And want to know how it forwards the client connection if a node fails.. Can anyone update the URL for this..There are a lot of information about it:

DHCP and SMB service failing

We have a X server with 10.5.5 installed.
This server is our main server with active settings for OD, SMB, DNS, DHCP and AFP.
At variable intervals the DHCP and SMB service gets corrupt.
here's excerpt from the server log:
Nov 15 04:19:59 FileServer servermgrd[54]: pipe(status) error: 24

Now this only happens when we leave the server admin app open on the specific server.
If we close the application the server seems to be working fine (for at least 3 weeks...).
We even reinstalled the server from scratch, but this problem is persistent...
Is this a bug en the Server Admin app?

Hi
Get into the habit of not leaving either of the two applications (Server Admin and WorkGroup Manager) open. Especially Server Admin. When you've done with the application quit out of it. If you can develop your command line skills (man serveradmin is useful), try and use these where possible instead. Best advice I can give you.
If your server is not configured as Advanced please ignore this advice.

2008 R2 PDC with DNS, File and Print Server Roles

Hi all,
we have a brand new Canon iRA7260 setup on 2008 R2 print server, which is also our DC, DNS, DHCP and File Server with latest PCL5c drivers downloaded from Canon's website as recommended at that time by the canon technician who assembled the
machine. All our laptops and desktops are running Windows 7 64-bit and after creating a GPO everyone got connected to the printer no problem, the printer has a static IP, same subnet as the print server and PDC, printer's port has been setup to RAW
and to spool documents, driver isolation setup to default.
All users are setup for secure print, so every print job they send to the printer stays on the printer until they walk up to the machine and release it by punching in a department's pin. Everything works great except for every morning a get a few complaints
that the jobs sent to the printer did not appear in the secure print folder. There is no errors of any kind on workstations and all I see in the print job logs on the print server is that document been spooled, printed and deleted. The strange thing is that
the size of the document that disappears is always shown as 0 bytes in size and 1 page long. And the whole process of spooling printing and deleting happens within 1 second according to logs. There is no errors or warnings in the log except for informational
events.
I just discovered that what actually fixes this issue for me is not even restarting the print spooler on the print server, but just login into the print server from my workstation via RDP with admin credentials. Once I login into the server remotely,
every print job sent to the printer afterwards from every workstation in our office appears as usual in users secure print mailboxes. Users don't even have to reboot their work stations, everything just starts working as usual. There is no overnight activities
on that server as all our staff leaves the offices by 8 p.m. the latest and the only thing that is running overnight is the Symantec's Backup Executive backup jobs. Is it possible that a back up job could somehow affect the print server/print driver settings
or put it into a "sleep" mode so it would require a domain admin login to the server to bring it back into operational state?

Hi, the print server had default permissions set after the role was installed. I just added domain users and authenticated users with print and view server rights. I don't think this is a problem though because Samsungs Brothers and Xerox printers
are working. It looks like some process that runs at night on the print server disallows users to print to the Canon printer when they come in in the morning. Login remotely with admin credentials into the 2008 R2 that has print server role installed and this
canon printer deployed via GPO fixes this immediately for all users. After the printer works fine until the last staff leaves the office. However when I come in in the morning everyone reports to me the same problem which again I'm able to fix by login with
my domain admin credentials. Could this be due to some special permissions that canon drivers require to be added that I'm not aware of? Or could this be caused by the overnight Backup Executive 2010 R3 backup job that kicks in at 9 p.m. every night?
Thanks
