RAC Internals

Hi !
I got stuck while verifying my understanding on the startup process of a rac architecture. I have a question in my mind that I can not answer to me and also failed when searched on net.
I want to know....
In a RAC setup (say 4 node RAC setup, version-10.2.0.4) what internally(steps and involvement of background processes) happens from the command: 'crsctl start crs' to all the instance came up and db in read-write mode without any error.
Please help me out.
Thanks,
GC

Not everything needs to be marked as internal. When you would issue the command, this would make the the read the entries from the */etc/inittab* . If you would go and check within the /etc/ folder, you would find there couple of folders including init.crs, init.crsd, init.cssd . These scripts would be read to start the clusterware stack.

Can the G4 accommodate external drives in addition to the 2 ATA internals?

Hi all,
I have a G4 dual 1GHz machine (Sales Order Number: M8667LL/A) with two 120 ATA internal drives. I am happy with them but I want to have more HD space. I read Apple's pdf file on G4's capacity and seems to indicate that this tower only will accommodate either two ATA drives or 3 SCSI drives internally. Since I already have the 120 ATA internal, I think I need to hook up external drives. Is this technically feasible? Will my machine accommodate external drives in addition to the internals? And if so, what if any are there limitations on the size? Also, I read a thread debate between USB 2.0 and firewire. It seems that the poster recommends firewire for being technically faster. Would you recommend also?

Hi, Speed Racer -
Your G4 QuickSilver '02 model is designed to have up to four internal ATA hard drives - two in the rear position on the two-drive bracket (sled), and one each in the other two positions. However, in order to use more than two internal hard drives you will need to add a PCI controller card in order to have a bus connection for the additional drives.
Using an ATA/100 or ATA/133 card, one which is 48-bit LBA compliant, will also allow you to use drives larger than 128GB on that card.
You can also use an SATA (Serial ATA) card instead, and SATA drives. The advantage of this is that newer Macs use SATA drives, so the drives would be more likely to be usable on a new machine if and when you get one. SATA also does not have the 128GB limit.
As far as external drives go -
The 128GB limit does not apply to firewire or USB.
Although your machine is both firewire bootable and USB bootable, your machine has USB 1.1, which is far too slow for most things, especially for booting. You should consider firewire only.
You can daisy-chain several firewire devices together - up to 16 devices per firewire port.
Although the specs for firewire on Macs state that the first two devices in a chain can draw power from the firewire bus, it is better to equip all firewire devices with external power - this may be standard with a device, or an optional extra. Doing this relieves the power supply in the Mac from the burden of providing power to the devices.
Note - one of the advantages for having firewire drives is that they are hot-connectable (can be added or removed without shutting down the Mac), hence are very portable. However, disconnecting a firewire drive while it is still mounted on the desktop can damage the drive. Before disconnecting a firewire drive, either shut the Mac down, or dismount the drive - to dismount a firewire drive, either drag its icon to the Trash, or select its icon and press Command-Y (Put Away in File menu); once it has been dismounted (its icon has disappeared from the desktop), it can be disconnected without damage.

About Oracle Internals

Hi all,
Could anyone tell me the link where I can learn much about oracle internals, which is the pre-requisite for advance performance tuning.
Thanks.

Hi Sir,
Was very happy to see you in this post, also i read your *"Oracle Database 10g Real Application Clusters Handbook"*. This book is really amazing for getting internal knowledge of RAC like Cache Fusion, Delayed Block Clean-Out, PI, BWR ......lot more ...
By the way i know very clearly about BWR and PI, but my doubt is related to Transaction Lock and Block Lock with respect to Current Image Block.
In chapter 12, Cache Fusion II or Write/Write Cache Fusion, Example 4: Getting a (Cached) Modified Block for Update and Commit ==> You have mentioned
"Instance A sends the dirty block to instance C over the interconnect. It downgrades the lock on the buffer from XCUR to NULL. It keeps a PI version of the block and disowns any lock on that buffer. Before shipping the block, instance A has to create a PI image and flush any pending redo for the block changed. The block mode on instance A is now NG1."
1. If Instance A is still performing DML transaction on the block, which means ITL slot is open on the header of this block....Then how come Instance A will transfer this block to Instance C along with open ITL....If suppose Instance A rollbacks the transaction then dont you think Instance has to do lot of work as Undo segments related to this transaction are residing in Instance A.
2. If Instance A will not transfer the active transction block then Instance C will do Disk ping which is an performance degrade...Am i saying right ?
3. If Instance A will transfer only when Instance C is willing to perform DML on other row on that same block, then how Instance C maintains active transaction shifting from Intance A to C and how Instance C maintains commit and rollback of active transaction in its buffer pefromed by Instance A ?

Yasser

MULTIPLE USERS 10G RAC ORACLE_HOME INSTALL WITH ASM/CRS

Hi,
We need to install multiple 10g RAC databases on a two node Sun servers. Below is our configuration:
1) Sun Solaris (ver 10) with Sun Cluster 3.2
2) One ASM/CRS install (by 1 OS account)
3) Four ORACLE_HOME 10g database install (by 4 different OS user accounts)
We would like to use one ASM instance for all four databases with appropriate privileges.
OS User:           OS Group
========      =========
oraasm           dbaasm - (ASM and CRS install owner)
ora1           dbaora1 - first db owner
ora2           dbaora2 - second db owner
ora3           dbaora3 - third db owner
ora4           dbaora4 - fourth db owner
I understand that certain privileges need to be shared between ASM/CRS and DB owners. Please let me know the steps to be followed to complete this install.
Thanks in advance.

Hi
Please read that: Documentation http://download.oracle.com/docs/html/B10766_08/intro.htm
- You can install and operate multiple Oracle homes and different versions of Oracle cluster database software on the same computer as described in the following points:
-You can install multiple Oracle Database 10g RAC homes on the same node. The multiple homes feature enables you to install one or more releases on the same machine in multiple Oracle home directories. However, each node can have only one CRS home.
-In addition, you cannot install Oracle Database 10g RAC into an existing single-instance Oracle home. If you have an Oracle home for Oracle Database 10g, then use a different Oracle home, and one that is available across the entire cluster for your new installation. Similarly, if you have an Oracle home for an earlier Oracle cluster database software release, then you must also use a different home for the new installation.
If the OUI detects an earlier version of a database, then the OUI asks you about your upgrade preferences. You have the option to upgrade one of the previous-version databases with DBUA or to create a new database using DBCA. The information collected during this dialog is passed to DBUA or DBCA after the software is installed.
- You can use the OUI to complete some of the de-install and re-install steps for Oracle Database 10g Real Application Clusters if needed.
Note:
Do not move Oracle binaries from one Oracle home to another because this causes dynamic link failures.
. If you are using ASM with Oracle database instances from multiple database homes on the same node, then Oracle recommends that you run the ASM instance from an Oracle home that is distinct from the database homes. In addition, the ASM home should be installed on every cluster node. This prevents the accidental removal of ASM instances that are in use by databases from other homes during the de-installation of a database's Oracle home.

Error while running runcluvfy.sh(11g RAC on CentOS 5(RHEL 5))

Oracle Version: 11G
Operating System: Centos 5 (RHEL 5) : Linux centos51-rac-1 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:19:18 EDT 2009 i686 i686 i386 GNU/Linux
Question (including full error messages and setup scripts where applicable):
I am attempting to install oracle 11g in a RAC configuration with Centos 5 (redhat 5) as the operating system. I get the following error
ERROR : Cannot Identify the operating system. Ensure that the correct software is being executed for this operating system
Verification cannot complete
I get this error message when I run runcluvfy.sh, to verify the my configuration is clusterable. I don't know why.
I edited the /etc/redhat-release and entered echo "Red Hat Enterprise Linux AS release 4 (Nahant Update 7)" to attempt to fool the installer into thinking its red hat 4.
But still shows the same message.
Anyone knows how to fix this ?
Please help me.

http://www.idevelopment.info/data/Oracle/DBA_tips/Linux/LINUX_20.shtml
runcluvfy.sh will not work on centos because the cluster verification utility checks the operating system version using the redhat-release packag and centos do this with his packages, so you must install and use redhat-release package
Get rpm-build to be able to build rpm’s:
[root@centos5 ~]# yum install rpm-build
Get source rpm of redhat-release
[root@centos5 ~]# wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/redhat-release-5Server-5.1.0.2.src.rpm
Build package:
[root@centos5 ~]# rpmbuild –rebuild redhat-release-5Server-5.1.0.2.src.rpm
Install newly generated rpm:
[root@centos5 ~]# rpm -Uvh –force /usr/src/redhat/RPMS/i386/redhat-release-5Server-5.1.0.2.i386.rpm

How to install 11gR2 RAC on 64 bit linux OS

I am completely new to this topic of RAC and need to be installing and standing up RAC on Linux 64 bit OS . I have good knowledge of installing oracle database ENTERPRISE version 11gR2.
Can you guide me as to how to start. I am looking for leads. Probably we will have 2 nodes.
Thank you very much for helping me in advance

If you are a My Oracle Support (Metalink) user, go check out these two notes created by the Oracle RAC Assurance Team. They are excellent.
NOTE: 810394.1 RAC Assurance Support Team: RAC Starter Kit and Best Practices (Generic)
NOTE: 811306.1 RAC Assurance Support Team: RAC Starter Kit (Linux)
In the Linux note mentioned above there is a link to a Linux Step by Step Instruction Guide. This step by step instruction guide is the best start to finish document I've seen for how to set-up and install Oracle RAC. I believe the guide is written for installing release 11.2.0.2.

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

RMAN, RAC, NFS, and server lock ups

Good day. My environment is:
--a 2-node RAC
--Enterprise Edition 11.2.0.3
--RHEL 5.1
The goal is to use RMAN to push backups to a shared NFS mount (on a different server). Both nodes will have access to this location (in the event one node goes down, the other can still run backups). Easy, right?
Wrong.
I've tried every NFS mount option in the book. Most work just fine, some don't. When I use the recommended NFS mount options:
rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp, vers=3,timeo=600, actimeo=0
or
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,noac,forcedirectio, vers=3,suid
The mount works normally. I can "ls" and "mkdir" and "touch" and "vi" and "cp" files back and forth from the NFS backup location to the RAC node all day long. No problems. However, when I try to do almost anything in RMAN which requires writing to the NFS backup location such as the command "backup archive all delete input;" (or even things as simple as a Crosscheck or RMAN configuration change which writes any changes back to the autobackup ControlFile) the node locks up. There are no errors (or if there are, I don't know where to find them), even when I use RMAN log.
Just to recap: I run a Crosscheck (or any RMAN process that writes to the NFS backup location), the node will lock up, and I can let it sit for a day, inaccessible, with CRSCTL on the other node saying it's offline, and the node will never come out of a "frozen" state. It cannot be pinged or connected to.
I think I can safely rule out NFS mount options at this point.
I understand (after extensive reading of MOS docs and testing) that RAC RMAN can and does suffer from inefficient I/O when writing to an NFS mount. I don't think that's the culprit either. The autobackup ControlFile is not that big and I cannot see how running a simple Crosscheck would lock an entire node.
I am hoping someone has encountered this in the past and hopefully it's just a simple misconfiguration somewhere.

My NFS line in /etc/fstab is (these options are for supporting 11.2.0.3, 11.1.0.7, and 10.2.0.4/5 simultaneously): server.domain:/NFS_Export /backup nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600 0 0
Before you installed GI, did you by chance do a yum update? I've encountered a similar issue which ended up being due to mkinitrd creating a corrupted kernel; mkinitrd is invoked during the GI installation when the ADVM drivers are added and in my case mkinitrd created a new kernel prior to the new kernel being installed. Second to that, make sure you have the matching kernel headers to your kernel version. If they are different then you could probably get away with just creating a new kernel with mkinitrd and relinking GI/RDBMS homes, but be prepared to wipe GI and reinstall.

Hello guys finally i find mistake i was doing
while configuring Public Ip for the nodes i was not giving Default Gateway .I was assuming as all these machine is in same network with same Ip range so they would not be needing Gateway but here my assumption mismatch with oracle well finally happy to see 11G r2 with GNS running on my personal laptop.

Hi,
Please post the alertlog ASM from node 1, crsd.log and ocssd.log from node 1
It might be because node 1 can't see asm disk or permission accidentally changed when the node rebooted

What could be the issue ????
Experts Please help me. Doing setup for the PRoduction Env...
Do response ASAP...... Thanks

Thanks Sebastian for your input.
yes. my lan2 is used for Cluster_interconnect which is having subnet 255.255.255.240.
Below are IPs used for RAC
Public
Node1: 10.10.1.173/255.255.240.0
Node2: 10.10.1.174/255.255.240.0
Private
Node1: 10.10.16.50/255.255.255.240
Node2: 10.10.16.51/255.255.255.240
Virtual
Node1: 10.10.1.191/255.255.240.0
Node2: 10.10.1.192/255.255.240.0
SCAN (Defined in DNS)
10.10.1.193/255.255.240.0
10.10.1.194/255.255.240.0
10.10.1.195/255.255.240.0
As you said, I will scrap GI Software again & will try with 255.255.255.0.
I Believe this Redundant Interconnect and ora.cluster_interconnect.haip present in 11.2.0.2.0 Version.
Oracle says:
Redundant Interconnect without any 3rd-party IP failover technology (bond, IPMP or similar) is supported natively by Grid Infrastructure starting from 11.2.0.2. Multiple private network adapters can be defined either during the installation phase or afterward using the oifcfg. Oracle Database, CSS, OCR, CRS, CTSS, and EVM components in 11.2.0.2 employ it automatically.
Grid Infrastructure can activate a maximum of four private network adapters at a time even if more are defined. The ora.cluster_interconnect.haip resource will start one to four link local HAIP on private network adapters for interconnect communication for Oracle RAC, Oracle ASM, and Oracle ACFS etc.
Grid automatically picks link local addresses from reserved 169.254.*.* subnet for HAIP, and it will not attempt to use any 169.254.*.* address if it's already in use for another purpose. With HAIP, by default, interconnect traffic will be load balanced across all active interconnect interfaces, and corresponding HAIP address will be failed over transparently to other adapters if one fails or becomes non-communicative. .
The number of HAIP addresses is decided by how many private network adapters are active when Grid comes up on the first node in the cluster . If there's only one active private network, Grid will create one; if two, Grid will create two; and if more than two, Grid will create four HAIPs. The number of HAIPs won't change even if more private network adapters are activated later, a restart of clusterware on all nodes is required for new adapters to become effective.
In my Setup, I am having Teaming for NIC's for Public & Private Interface. So I am thinking to break teaming of NICs because HAIP internally searching for next available NIC & not getting as all 4 are already in used with OS level NIC teaming.
My only Concern is, as I am going to change subnet for the Private IPs, should I change Private IP address ????
Thanks for the Support...

Manish
