Parameters of NFS in Solaris 10 and Oracle Linux 6 with ZFS Storage 7420 in cluster without database

Hello,
I have ZFS 7420 in cluster and OS Solaris 10 and Oracle Linux 6 without DB and I need mount share NFS in this OS and I do not know which parameters are the best for this.
Wich are the best parameters to mount share NFS in Solaris 10 or Oracle Linux 6?
Thanks
Best regards.

Hi Pascal,
My question is because when We mount share NFS in some servers for example Exadata Database Machine or Super Cluster for best performance we need mount this shares with specific parameters, for example.
Exadata
192.168.36.200:/export/dbname/backup1 /zfssa/dbname/backup1 nfs rw,bg,hard,nointr,rsize=131072,wsize=1048576,tcp,nfsvers=3,timeo=600 0 0
Super Cluster
sscsn1-stor:/export/ssc-shares/share1 - /export/share1 nfs - yes rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,vers=3
Now,
My network is 10GBE
What happen with normal servers only with OS (Solaris and Linux)?
Which parameters I need use for best performance?
or are not necessary specific parameters.
Thanks.
Best regards.

GUIDE: Oracle VM VirtualBox and Oracle Linux NIC bonding

Author: Dude
Date: 01-Jun-2013

Last updates:

The following is provided in the hope that it might be useful. If you wish to use it for the purpose of reference, presentation or education, please include the link or information to this forum posting. Thank you!
What is Linux network interface bonding? Simply put, the Linux system provides a kernel driver, which can create a logical network device (bond) using 2 or more Network Interface Controllers (NIC) to accomplish link-aggregation and adapter fault-tolerance. For more information, please see the Deployment Guide at https://linux.oracle.com/documentation/
The channel bonding interface supports several modes of operation. In a typical active-backup set up for fault-tolerance, the system performs MII-based health monitoring of the network interface slaves (eth0, eth1) and assigns them according to bond options and interface availability. In active-backup mode (mode 1), only the current active network device is seen externally.
Linux bonding for fault-tolerance under Oracle VM VirtualBox does not seem to function as advertised. Searching the Internet for more information shows that other people have tried to set up Linux bonding using various virtualization products, virtual host network adapter and bonding options, but without success.
It appears the management of Media Access Control addresses (MAC) interferes with internal routing methods between the host and the virtual machine guest. Using the modinfo bonding command (fig. 1) shows a listing of available parameters for the bonding kernel module. The fail_over_mac parameter addresses the Mac address issue in VirtualBox.
Fig.1
# modinfo bonding
filename:       /lib/modules/2.6.39-400.17.1.el6uek.x86_64
                /kernel/drivers/net/bonding/bonding.ko
parm:           fail_over_mac:For active-backup,
                do not set all slaves to the same MAC;
                0 for none (default), 1 for active, 2 for follow (charp)
Configuration Example
Virtualization Product: Oracle VM VirtualBox 4.2.10
VM Guest OS: Oracle Linux 6.4 (x64)
VM adapter settings: Bridged Adapter, Paravirtualized Network (virtio-net)
Adapter1 (eth0): 080027436617, en0, Ethernet 1
Adapter2 (eth1): 08002708F36A, en0, Ethernet 1
Note: If you wish to reset the network adapter names and MAC addresses used by the Oracle Linux guest system, erase the content of /etc/udev/rules.d/70-persistent-net.rules and restart the virtual machine.
1. Create or modify the following configuration files:
/etc/modprobe.d/bonding-eth0_eth1.conf
alias bond0 bonding
/etc/sysconfig/network-scripts/ifcfg-bond0
DEVICE=bond0
IPADDR=10.0.2.12
NETMASK=255.0.0.0
GATEWAY=10.0.0.138
DNS1=10.0.0.138
DNS2=8.8.8.8
ONBOOT=yes
BOOTPROTO=none
USERCTL=no
BONDING_OPTS="mode=1 miimon=100 fail_over_mac=1"
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
/etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes
USERCTL=no
2. Restart the system or network services (root):
Fig. 2
# service network restart
Configuration Test
Enter the following commands as user root to verify proper operation of NIC bonding:
Fig. 3
# tail /var/log/messages
bond0: setting mode to active-backup (1).
bond0: Setting MII monitoring interval to 100.
bond0: Setting fail_over_mac to active (1).
bond0: Adding slave eth0.
bond0: making interface eth0 the new active one.
bond0: first active interface up!
bond0: enslaving eth0 as an active interface with an up link.
bond0: Adding slave eth1.
bond0: enslaving eth1 as a backup interface with an up link.

          UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1
During the above test, the client network connection from host 10.0.0.1 (ssh) was maintained without any noticeable interruption. As it can be seen from the syslog and ifconfig command output, the bond0 interface was automatically assigned either the MAC address of eth0 or eth1 and the fail-over worked as advertised.
Good luck!

Smart flash cache and Oracle Linux 6

I can't use smart flash cache feature on Oracle database 11.2.0.3.0 I installed on Oracle Linux 6.
I installed Oracle database 11.2.0.3.0 on Oracle Linux 6.1 and try to use smart flash cache feature,
I got this error when I start database:
ORA-00439: feature not enabled: Server Flash Cache
ORA-01078: failure in processing system parameters
My environment are:
OS: Oracle Linux 6.1 (x86_64)
Kernel: 2.6.32-100.34.1.el6uek.x86_64
DB: 11.2.0.3.0
Related parameter in pfile I used to start database to use smart flash cache feature,
*.db_flash_cache_file='/d09/db_flash_cache/db_flash_file.raw'
*.db_flash_cache_size=32G
I have accomplished this on Oracle database 11.2.0.2.0 on Oracle Linux 5.5 before, I don't think new version of database cause the issue but I'm not sure is there any smart flash cache issue with the Oracle Linux 6.1?
Note:
I need to use Oracle Linux 6.1 instead of Oracle Linux 6.2 and can't updated the kernel to UEK2 because the SSD PCI-E card only support on this distro and kernel version.

Hi;
Oracle Enterprise Linux was changed to Oracle Linux, isn't ?
Oracle stopped calling their Linux distro as "Oracle Enterprise Linux" since OEL5.5 or 5.6 (I'm not sure). Therefore, today there is Oracle Linux only? If so, I'm using OL6.1 also means OEL6.1, correct?
But, If the doc really means Oracle Enterprise Linux only then should it means OEL5.5 or 5.6?AFAIK both refer to Oracle Linux.If somebody mention they have OEL6.1 or Oracle linux 6.1 than I accept it Oracle linux(Enterprise)
You may see FAQ documents:

If you have still dubt than I suggest rise thread at Forum Home » Linux » Oracle Linux forum part

Install questions on OVM Manager and Oracle Linux

I installed OVM Server 3.0.3 on a 64-bit server class box.
Getting tight with a spare box, I tried to install OVM Manager on the Oracle VirtualBox as a VM and also to install it on the top of OVM Server on the same hardware box but neither has been successful.
So, I'm thinking of rather installing OVM Manager on one of my laptops.
Before proceeding to wipe out the data on my laptop, I'd like to check couple of things:
1. I take it that the 32-bit OVM Manager should have no problem working with 64-bit OVM Server, correct?
2. The OVM Manager itself doesn't include with a bootable Linux image and should be installed on the top of a pre-installed Linux (e.g., Oracle Linux), so I need to install Oracle Linux first on my laptop and install OVM Manager on top of it, right?
Thanks for your help in advance!

You'll need at least 4GB of RAM for the Manager for a test/development environment, with 8GB+ recommended for Production, to cover both Oracle Database SE and Oracle WebLogic.

Windows 2008 R2 ODBC connect to Oracle Linux with 11g db

Hi
i installed a fresh oracle linux and installes 11.2.0 database server. the server works fine but i have a proplem to connect to the database from a windows 2008 r2
client. For the client connection i installed the oracle instantclient on the windows system. Now i want to configure the system dsn to connect to the oracle
server like this
data source description: vSphere 64

then i go to TEST connection
Service Name: VCDB

so i copied the tnsnames.ora from the server to the client
then i get

here´s my tnsnames.ora from the client
VCDB =

"connectstring" is not a valid attribute with Oracle's ODBC driver, so since there is no datasource attribute specified, the app is trying to connect to a local database, and since you don't have one, you get 12560.
To resolve the problem, pass DBQ= instead of CONNECTSTRING=

Installing 11i on Solaris and migrating 8.0.5 to new 8.1.6 database

I've installed 11i (several times) on a new Sun solaris server. I also selected it to install a fresh database. On another server we have 11.0 and 8.0.5 database. We are using a new server to install 11i and we want to move our database over. I managed to transfer all database files over to the new server and upgrade to 8.1.6 (succeeded)
How do I proceed now to get the 11i applications to use the database i've transferred over. Is this possible??? Can't find any clear documentation on how to merge this database into the applications 11i.
Thanks

Gina, I am attempting something similar... but it involves moving an exisiting installation from HP-UX to Solaris, so I cannot move the datafiles... If I run into a method that helps both of us, I will let you know... as of now, I am installing fresh on Solaris and going to try to run upgrade scripts on existing 10.7 and exp/imp into the new instance on 11i (Solaris).
Let me know of anything you find out that could help me, and I will do the same...
thanks

and listens to the ethernet and airport address.
When do you get the problems ?

Upgrading Oracle Linux with Oracle Unbreakable Linux Kernel

Hi all.
I'd like to upgrade an Oracle Linux OS with unbreakable linux kernel.
Current version is :
[oracle@union ~]$ uname -r

Which steps needs to be performed?.
I know i must be at 2.6.32. Also Unbreakable Enterprise Kernel is available for x86-64 servers.
Q: How do i know if my distro is x86 or x86-64?

Solaris 10 system freezes with ZFS + NFS

I've been playing around with Solaris 10 and attempting to create a file server using ZFS + NFS. While writing to the NFS share over my network the solaris system will completely freeze requiring me to hit the power button. It is a total freeze, the GUI becomes unresponsive and you are unable to ssh into the machine as well. The amount of data I can write before the system freezes varies, sometimes only a few megs, other times a few hundred.
I'm running fully up to date x86 Solaris 10 on a system with 512MB of RAM. I know this isn't the optimal solution for a ZFS server but I don't see how this could be the source of the problem either. I have tried with ethernet and wireless interfaces as well as using samba instead of NFS and all have the same issue. Writing files to Samba and NFS shares on the UFS file system on the same box didn't exhibit this problem. The logs don't contain anything about this issue as far as I can tell.
My zpool has 3 PATA disks of different sizes and have no errors. While tracking down the problem I had top going and didn't see any out of the ordinary memory or CPU usage up until the freeze.
I have been troubleshooting this issue on and off for a while and figured it was time to look for some help. I'm an experienced Linux user but quite a novice when it comes to Solaris so I am hoping someone could point me in the right direction.
Thanks in advance.

Dual booting Windows 8 and Arch Linux with UEFI

Hi all!
I'm trying to install Arch Linux on my computer where I already have Windows 8, and I'm getting a little stuck when it comes to the partitioning.
Following the beginner's guide and the method here: https://wiki.archlinux.org/index.php/Un … n_in_Linux for setting up the partitions properly, regarding UEFI. My problem is that when using cgdisk to set up a new EFI system partition (ef00), I get an error message when trying to write the partition table (just saying that something went wrong). I figure the problem is that I already have a partition like this (correct me if I'm wrong), but it really looks like it succeded (see info below). So my question is: How do I preceed to keep my Windows 8 installation happy, but installing Arch? Do I remove the old EFI system partition and create a new one, or is there some method that allows me to edit the already existing one, to allow me to dual boot Windows 8 and Arch?
My partition table now looks like this:
Part. # Size Partition Type Partition Name
1007KB free space
1 500MB Windows RE Basic data partition
2 300MB EFI System EFI system partition (this one was already present on my system)
3 128MB Microsoft reserved Microsoft reserved partition
4 63.5GB Microsoft basic data Basic data partition
8 512MB EFI System EFI System partition (this is the one I tried to create when I got the error message)
5 29.5GB Linux filesystem Arch (this is where I was going to put my Arch installation)
6 22GB Windows RE Basic data partition
7 1024MB Windows RE Basic data partition
615KB free space
Just for the record; I only created partition #8 and #5.
Any help is appreciated! And sorry for beeing a total noob, but I really suck at this.

There's really very little to do to share an ESP between OSes. Most OS installers will auto-detect the ESP and use it. Problem solved. For Arch it may be a bit more effort just because Arch uses a more hands-on installation process, but I've only done a couple of Arch installations, and the last one was several months ago, so I don't recall the details clearly enough to comment.
And how big will the partition need to be? The beginner's guide says 512MB or higher.
I don't know what was in the mind of the author, but my guess is that's because that's roughly the cutoff point where mkdosfs starts creating FAT32 by default rather than FAT16. The ESP is officially supposed to be FAT32, not FAT16, although FAT16 usually works OK. It's also possible to create FAT32 on smaller partitions by using an explicit option to mkdosfs ("-F 32").
The optimal size of the ESP depends on the files stored on it. If you don't store your Linux kernels, something as small as 100MiB is usually adequate; but a few Linux kernels and their initrd files can consume twice that amount. My own recommendation is for the ESP to be 200-500MiB.
The only error message I got from cgdisk is "Problem saving data! Your partition table may be damaged!", however booting Windows again works fine. Parted did not complain about antything.
Use the "verify" function in cgdisk. That will reveal any problems with the data structures. If a verify turns up OK, then that means that cgdisk ran into some sort of disk problem. Running gdisk rather than cgdisk and using the gdisk "w" option (without making any changes) may produce a more helpful error message.

OS 64bit and Oracle 10G with Patch are 32bit

Hello Experts
My problem little bit typical. I am new in Oracle.
I am going to install Solution Manager 4.0 with Oracle 10G on Windows 2003 64bit, IBM x3650 Server.
I have already installed Oracle 10G 32bit, with 32bit patches,. Its a general Oracle without sapserver.cmd file, so I have installed with setup.exe file. I have mounted the database, created the listener.
New there are three directories 1) D:\Oracle\Product\10.2.0\admin\DEV10\adump, bdumpetc. db\admin
2) E:\Oracledata\DEV10\control01.ctl, 02.ctletc.
3) G:\ Archives
Now I am trying to install SOLMAN with sapinst.exe 64bit windows, after giving the export path, it shows the massage Oracle software not installed. Install oracle software first. Means SAP does not recognizing Oracle.
After that I am trying to install with sapinst.ext 32bit, now it is excepting the export path. After two steps it is asking for Kernal & Oracle client path. What is oracle client? I think it is asking for OCL10264.SAR file.
My Questions are:
1. I have to download form market place 32bit or 64bit file?
2. My oracle installation is proper or not.
3. Where I have to uncar that file. Please provide me the proper path, step by step.
4. I am going to the right direction or I am a wrong. Please help me .. I dont want to format the machine.
Please explain me in details step by step. I am in the problem, I have no friends in this line.
Best Regards
Sunil

> My Questions are:
> 1. I have to download form market place 32bit or 64bit file?
if you're installing on 64bit you need to install the 64bit Oracle binaries. And not only those but the actual patch 10.2.0.2 and the necessary interim patches before you can start to load the database. Additionally you should use the provided script to install the database, not setup.exe
Additionally you will need a 64bit JDK from Sun (avaible on the link in note 941595).
> 2. My oracle installation is proper or not.
No - you need a 64bit Oracle - and not the installation CDs downloaded from the Oracle site but those from SAP.
> 3. Where I have to uncar that file. Please provide me the proper path, step by step.
Where you have to uncar WHAT file?
> 4. I am going to the right direction or I am a wrong. Please help me .. I dont want to format the machine.
The proper approach would be to download the installation guide at
http://service.sap.com/instguides
and read all the installation notes, download the patches and install them as suggested in the guide before trying to start the installation. The preparation and planning of the system will take some time before you actually start to install.
A SolMan installation is no Microsoft Office where you do "setup - continue - continue - finish"...

[SOLVED] Dual boot windows 7 and arch Linux with seperate hard drives

Ok so I'm stuck trying to get my computer to dual boot windows 7 and arch. They are installed on different hard drives and I have grub 2 as the boot loader. I can't find any tutorials on how to do it with seperate hard drives I know how to do it if they are on the same hard drive. Also I want windows on the "first" hard drive how do I check to see which one it considers the first?

Not from the BIOS. He would need to physically open up the computer and switch the cables between them (or add another drive).
There's no actual performance increase in changing this order. Performance increase is when you have the partitions as close to the beginning of a HDD as possible, where the platters spin faster (basic mechanics, not to be confused with CD/DVD, which are being written from the inside-out to prevent errors after extended usage), and it especially doesn't apply to SSDs whatsoever.
You may be right about that. I remember I had to do this a while back but I probably switched the cables. It also messed up the drive mapping in Windows 98 if I remember correctly.

Start-up / shut-down (and other) problems with ZFS over iSCSI

Hi,
I've had a limited time in which to try some concepts on an evaluation x4500 server. This is unfortunately my last day, so by the time anyone can reply I will probably not be able to to further tests, but maybe someone will be able to reproduce the issues.
I'm using the evaluation server to export some iSCSI targets, and I'm connecting to them from my laptop, which has a fresh installation of SXDE 01/08. I was able to attach to the targets with
iscsiadm add static-config \
iqn.1986-03.com.sun:02:f4281081-c3fc-e448-c8f0-943d8861c9e8,192.168.15.62
iscsiadm add static-config \
iqn.1986-03.com.sun:02:371c6fe7-f0c8-e02c-c865-baef90fb71ce,192.168.15.62
iscsiadm add static-config \
iqn.1986-03.com.sun:02:ee74d5de-3046-6295-f35e-afe60e13db23,192.168.15.62
iscsiadm modify discovery -s enableThis made the appropriate entries appear in /dev/dsk so I could then set up a simple zpool and zfs filesystem with:
zpool create -m none dPool c3t010000144FA70C1400002A0047C2BF73d0 \
c3t010000144FA70C1400002A0047C2BF81d0 c3t010000144FA70C1400002A0047C2BF8Bd0
zfs create -o mountpoint=/data -o sharenfs=on dPool/dataThe general concept I'm testing is having a ZFS-based server using an IP SAN as a growable source of storage, and making the data available to clients over NFS/CIFS or other services. In principle this solution should also allow failover to another server, since all the ZFS data and metadata is in the IP SAN, not on the server. Although not done in this example it should also be possible to run raidz across multiple iSCSI disk arrays. However, it's not been a bed of roses. I've had a lot of errors in dmesg like the following, which I think are causing zfs/zpool commands to stall at times:

Surely they should be talking the same language!
The main problems however are with shutdown and start-up. On occasions, I suspect that the ordering of ZFS, iSCSI and network services gets a bit out of sync. On one occasion the laptop even refused to complete the shutdown because it was reporting a continuous stream of console messages like

943d8861c9e8I also get these on start-up, where it looks like ZFS tries to load the zpool configuration before iSCSI has found the disks, and even worse, iSCSI is starting up before nwamd has time to do its network auto-magic, and complains that the devices are unavailable.
If these problems sorted themselves out after everything came up, I wouldn't really mind some temporary complaints in the log file, but what I get after a reboot is a working zpool but an unmounted ZFS filesystem! Here is what I have today:

Since zfs is supposed to take care of its own mounts rather than using vfstab, I can't use "mount /data" to force this to mount. The only workaround I've found is to export and import the zpool. Then I get the filesystem to reappear:
bash-3.2# df -h /data
Filesystem             size   used avail capacity Mounted on
dPool/data              29G   480M    29G     2%    /dataDoes anyone know if these are known issues with snv_79b, and is there a fix available or in the works?
TIA,
Graham

EasyE, Welcome to the discussion area!
(a) Call Apple and get your iMac G5 fixed since it is in the repair extension group. Don't waste your time doing anything else.
(b) This area is for discussing the iMac G4. Since you have an iMac G5 in the future you should post in the iMac G5 discussion area.

After water imersion and changing battery when plugged into computer the computer and shows file with photo storage but when trying to access info the message showes 0 photos.

Trying to recover I Phone 4 storage after I Phone water immersion. How can the phone be restored?

You will need to use a data recovery firm that can directly access the flash memory. It will be expensive.

Oracle Linux and SSH

Hallo!
I have a MacBook Pro 64 bit Version: 10.8.5 .
I installed VirtualBox 4.3.4 on it.
I used to install Debian Guest OSs.
I used under Network 'NAT' with Port Forwarding
There I mapped the Port 22 of the Guest OS with 60xx Ports.
Then I opened the shell on my Mac and did a ssh connection for example in the following way:
ssh -p 6011 root@localhost
And it worked always fine.
Then I installed Oracle Linux6 on my VirtualBox.
And I did a Port Mapping: Port 22 on Oracle Linux with 6017 on my Mac.
When I do
ssh -p 6017 root@localhost
it comes
ssh_exchange_identification: Connection closed by remote host
I think that has anything to do with the configuration of /etc/ssh/sshd_config?!
Can anybody show me how this file should look like?
Or do I have another problem?
Thanks for any help!
Gerhard

Hi Dude!
Thanks for your comments!
I use 'bridged network adapter' if I want to connect from my 'Guest'-OS to the Internet.
In my case I want to configure my Mac with its OSes as a 'Stand-Alone' Machine
(I live in Mexiko on the Countryside and often I don't have connection to the Internet).
That means, that my Mac is my Client and my Host-Server at the same time.
I install a database on my 'Guest OS', start my 'Guest OS' and that all.
All the rest I want to do, is to access to my 'Guest OS' from my Mac.
I do all my SQL, PL/SQL and DBA stuff from Oracle SQL Developer installed on my Mac.
I work with APEX and I access to the Database installed on my OS via my Browser installed on my Mac.
And for any work on my Guest Linux OS, I do that with my Mac Shell.
I did the same for many time with my Linux Guest OSes Debian and Ubuntu.
And it worked always fine.
But I never tried it with RedHat Systems.
I compared my /etc/ssh/sshd_config of my Oracle Linux OS with /etc/ssh/sshd_config of my Debian OS.
And the configuration is very different.
So I don't think, that it is a problem of my VirtualBox Network Configuration.
If it would be a problem of my VirtualBox Network Configuration, why does it run with my Debian OSes without problems?
Thanks for any help!
