Crs question for rac
on RH ES3 Update 5, Oracle 10.1.0.3....
Due to some network reconf. I reinstalled CRS.
I reconfigured VIPCA and NETCA.
My current status on this rac is:
VIP is running on node: hp1
GSD is running on node: hp1
Listener is running on node: hp1
ONS daemon is running on node: hp1
Problem: When I reboot, none of these resources come up automatically. How can i configure so that it can start during reboot.
Thanks in advance,
VT
The term rolling upgrade refers to upgrading different databases or different instances of the same database in a RAC environment, one at a time, without stopping the database. Oracle supports the rolling upgrade of Oracle RAC (not OS like I wrote previously) in a cluster when both versions of the operating system are certified with the version of the Oracle Database you are running. Rolling patch upgrades are not available if the Oracle Database software is shared across the different nodes. This is the case where the Oracle home is on Cluster File System (CFS) or on shared NFS volumes. The feature is only available where each node has its own copy of the Oracle Database software.
I doubt that Redhat or Oracle Linux will support in-place upgrades from version 4 to 5. Your only option really available might be to split the RAC cluster and completely setup each node from scratch, than rebuild the cluster. There could be of few changes between EL 4 and 5 that may affect your ability to run a mixed cluster, i.e. raw device support. Sorry, I'm afraid I cannot give you any other practical advise. Perhaps you might want to check the RAC forum at RAC, ASM & Clusterware Installation
To answer you question about the difference with Oracle Linux. The same versions of Oracle Linux and Red Hat Enterprise are binary compatible. For Oracle Linux 5.5, x86_64, you have an option to install the Unbreakable Enterprise Kernel (UEK), which contains a newer and Oracle optimized version of the kernel, currently 2.6.32. Oracle Linux provides a free public yum repository for software management and other Oracle specific packages. For access to patches you need a subscription to the Unbreakable Linux Network (ULN).

Storage related question for RAC
Hi Gurus,
I have a question here about the storage design. My company has 2 node Oracle RAC already setup on Linux with 11g for clusterware, ASM and 10g for database(for application support we are using still 10g for database). This RAC is dedicated for one database and shared by several applications.
Now, we decided to add two more nodes and additional storage to it.
The existing storage uses EMC SAN DMX 4574 (raw partitions) disks. And the additional storage disks provided by our storage team are EMC SAN DMX 3752.
Is it possible to combine these two different DISK (different series from same vendor) into one single storage sub system visible to entire RAC Database? All the 4 nodes will be used for the same database and application. Its a production system so we wanted to confirm and proceed further as we dont have a test scenario.
Shall we connect these different disks to the switches so that ASM can see all the disks at once and can be used for database?
Please advise.
Regards,
vasu

Its a >production system so we wanted to confirm and proceed further as we dont have a test scenario.First of all, You have to ask the OS support team in order to see if there is any kind of problem mixing it. I don't think it would be a problem, but as you don't have any test environemnt, You'd better ask them.
For the ASM side, it's not a problem, You can work with this kind of configuration. In fact I have a couple of environemnt using this configuration. I'm using a expensive storage with a better performance to critical tablespaces, and a lower cost storage to put historical data and other kind of data that are not accessed every time.
Shall we connect these different disks to the switches so that ASM can see all the disks at once and can be used for database? Well,
As I told before, I don't think it would be a problem, but again... You should ask the OS support team. For the ASM side, You shouldn't mix disks with diferent behaviour in the same diskgroup, You should use disks with the same size and similar/equal performance characteristics. As ASM balances the I/O over the disks in a ASM diskgroup, it's important to configure in this way in order to avoid performance problems.
Hope it helps,

CRS HOME & 9iR2 RAC ORACLE_HOME Different Owners
Facts:
2 Node Cluster, Sun T2000
O/S: Sun Sparc Solaris 64 bit 5.10
3rd Party Clusterware - Veritas Storage Foundation for RAC (SFRAC) 5.0 MP3
CRS: 10.2.0.4
CRS is owned by oracle:dba (with the exception of anything owned by root)
9iR2 (9.2.0.8) RAC RDBMS ORACLE_HOME is owned by oraofsg:dba
9iR2 (9.2.0.8) RAC Database Name: ofsg
10gR2 (10.2.0.4) RAC RDBMS ORACLE_HOME is owned by oracle:dba
Metalink note 220970.1
Misc. Info:
Action: /var/opt/oracle/srvConfig.loc was renamed after 9i database and GSD stopped prior to installing CRS.
Why?: 10g CRS chose to use 9i's srvm.dbf rather than the file system I had created for the 10g CRS cluster registry.
Task at Hand:
Need to register 9.2.0.8 RAC database ofsg under 10gR2 CRS.
Issue:
As 9i RAC database owner oraofsg with the 9i RAC environment set, and 9i GSD down:
srvctl add database -d oraofsg -o /sv01/sw/oraofsg/ofsgdb/9.2.0
PRKR-1005 : adding of cluster database ofsg configuration failed, PROC-5: User does not have permission to perform a cluster registry operation on this key. Authentication error [User [oraofsg] does not match with initialized user] [0]
Question: Has anyone successfully registered a 9i RAC database under 10g CRS?
Thanks for your consideration.
Regards,
JerryHi
CRS_HOME must be owned by a different user:group (preferably root) than $ORACLE_HOME (owned by oracle), for several reasons like patching.
Please note also that you will need an ASM dedicated home and also a AGENT_HOME that can be owned by oracle.
Hope this helps. -
Is a gateway mandatory for RAC environment?
Question:
Is a gateway mandatory for RAC installation, general on RAC environment?
*..when yes, why?*
Many thanks
I make this test with my only one RAC node
1. Run with gateway:
[oracle@linux1 ~]$ crs_stat -t
Name Type Target State Host
ora....SM1.asm application ONLINE ONLINE linux1
ora....X1.lsnr application ONLINE ONLINE linux1
ora.linux1.gsd application ONLINE ONLINE linux1
ora.linux1.ons application ONLINE ONLINE linux1
ora.linux1.vip application ONLINE ONLINE linux1
ora.orcl.db application ONLINE ONLINE linux1
ora....l1.inst application ONLINE ONLINE linux1
ora....test.cs application ONLINE ONLINE linux1
ora....cl1.srv application ONLINE ONLINE linux1
[oracle@linux1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node linux1All thing seem correct!
2. run without gateway (blank setting):
[oracle@linux1 ~]$ crs_stat -t
Name Type Target State Host
ora....SM1.asm application ONLINE OFFLINE
ora....X1.lsnr application ONLINE OFFLINE
ora.linux1.gsd application ONLINE ONLINE linux1
ora.linux1.ons application ONLINE ONLINE linux1
ora.linux1.vip application ONLINE OFFLINE
ora.orcl.db application ONLINE OFFLINE
ora....l1.inst application ONLINE OFFLINE
ora....test.cs application ONLINE OFFLINE
ora....cl1.srv application ONLINE OFFLINE
[oracle@linux1 ~]$ srvctl status database -d orcl
Instance orcl1 is not running on node linux1Something is false!By default, the server's default gateway is used as a ping target during the Oracle RAC 10g VIP status check action.
Upon a ping failure, Oracle will decide that the current interface where the VIP is running has failed, and will initiate
an interface / internode VIP failover.
In above case, we used just one node for CRS installation, so the VIP coudn't failover to other nodes and thus reported additional error like :
CRS-1006: No more members to consider
CRS-0215: Could not start resource 'ora.dbtest2.vip'.
Try ->
A parameter FAIL_WHEN_DEFAULTGW_NOT_FOUND in the file
$ORA_CRS_HOME/bin/racvip to address this problem.
The following steps will fix the VIP starting problem for above mentioned scenario.
1- stop nodeapps
2- As root,
vi the script $ORA_CRS_HOME/bin/racgvip and change the value of
variable FAIL_WHEN_DEFAULTGW_NOT_FOUND=0 .
3- start nodeapps and you should see the resources ONLINE
You may proceed with netca and dbca to create a RAC database after this. -
Urgent help needed in configuring X1151A for RAC cluster
for RAC requirements I have to configure this card to use the interface name of ce1 but I have tried changing slots and puting /etc/hostname.ce1 file out there but it fails .. it always comes up as ce0.
my question is : How can I cofigure this card to come up as ce1 ? in the other box I had to do nothing .. i just placed the /etc/hostname.ce1 file with hostname and it works perfect.
can you please email me a copy of your response at [email protected] ?
thanks
SamiLook for "ce" instances in the /etc/path_to_inst file. You'll need to change the lines so that the hardware path you want is "1".
Keep a backup and write down the pathname. You can give that path to a 'boot -a' prompt if anything bad happens.

Question about RAC 10g on server running AIX and domain name changes
We have several 10g clusters running on IBM p-Series AIX servers, and our company is changing the domain name for our network. I am concerned that if we do not change the domain names in the TNSNAMES.ora file and also the /etc/hosts file on each server, the cluster will no longer function. We are using CRS (version 10.2.0.3) and ASM within each cluster.
Does anyone know where I can find information about changing the domain name that was set up as part of the CRS and database installs for RAC? Does anyone have experience doing this, and would be willing to share a few insights? Thanks in advance for any advice you can give!You may be able to use the VIPCA utility for RAC to change or modify the public and private settings for your domain names on AIX. Also, the Oracle 10g DBCA "Database Configuration Assistant" should be of use to change your settings for your RAC environment.
Also, see here for a good IBM Redbook that covers Oracle 10g RAC on AIX platforms:

NETCA listener configuration error for RAC database
Hi,
WE have a RAC setup on 2 nodes and now we want to change the default listener port for RAC database.
Database ver: 10.2.0.4
We now that srvctl does not work to add listener manually to CRS.
We are now using netca to create new listener on both the RAC nodes but it gives error throwing :
Problem in configuration : Node(S): hostname
Try again...
When we try to start the listener say listener_I it throws following error:
Problem in configuration :node1
Listener start to failed:Listener may already be running
CRS-0215:Could not start resource
This is urgent
any help is appreciated.

I was reading the article about installing the RAC.
My conclussion , I can have till 127 instaces of a Oracle 10G database, working simultane. That is good really good and powerfull.
My questions
1º). ¿Can I have , by example, 3 , or any other number, of computer working with a HTMLDB instance or Oracle Aplication Server everyone serving pages to Internet and all then conect to one of those nodes? I think that yes, but prefer confirmation
2º) In case of failure of any of these nodes, broken computer ,by example, and I need to replace it, or I want add new nodes to a RAC system. ¿How I can do this? or ¿Where I can find documentation about this?
thanks for your help.Is posting Question about RAC some kind of thought experiment on clustering? Like, if you post the same question several tyimes do you get faster answers?

Solutions for access as ROOT for RAC DBA duties
Our Networking Team and Applications Team are going through some growing pains. We are trying to resolve what permissions should be given to a RAC DBA. Our RAC DBA is responsible for Oracle Clusterware, Oracle Automatic Storage
Management and Oracle RDBMS software. The OS, Server and Storage Subsystem are the responsibility of the System Administrator. We have the following Environment:
Production and Test (RAC)
Oracle Enterprise Linux 5 update 2
Oracle Clusterware 11.2.0.2 -- Grid Infrastructure
Oracle ASM 11.2.0.2
Oracle Database 11.2.0.2 EE
Development (Single Instance)
Oracle Enterprise Linux 5 update 2
Oracle ASM 11.2.0.2 -- Grid Infrastructure
Oracle Database 11.2.0.2 EE
As the RAC DBA, I have identified the following areas that require ROOT for RAC and Single Instance DB's; however, I understand there may be more:
diagcollection.pl
- diagnostic tool for Oracle Clusterware and may be requested by Oracle Support
ocrconfig
- to repair ocr configuration issue (add, replace and remove requires root)
srvctl modify
- required root to change ip address
tar
- TAR Grid Infrastructure Directory structure preserving files with ROOT ownership
cluvfy
- cluvfy fix it scripts need to run as ROOT
- some cluvfy commands under 11gr1 would only run properly for -post cfs check as ROOT in our last installation
ASM Libraries
- ROOT required to install and configure ASM libraries
fdisk - l
- this is used to see disks attached which is relevant when ASM disks are not mounted
/etc/sysconfig/oracleasm
- oracleasm loading configuration file
/usr/sbin/oracleasm
- to make disks available to ASMLIB (scandisks etc.)
/usr/sbin/asmtool
- asm config tool due to bug
asm cluster file system
- some commands require ROOT (mounting etc.)
- acfsutil
/var/log/messages
- loading errors ohas and oracleasm would be logged here
cvuqdisk
- needs to be loaded for new install
root.sh
- script needed to run at install, upgrades and patching
oraInstRoot.sh
- script needed to run at install
rootupgrade.sh
- upgrade script
roothas.pl
- upgrade script
ocrcheck
- check for ocr corruption
- corrupt check portion requires ROOT
- oracle local registry
Grid Infrstructure
- .runInstaller from Grid Infrastructure
- includes upgrades
asm configuration assistant (asmca)
- configuration of asm diskgroups
- vol mgr for asm disks
ocrconfig
- ocr configuration tool
- ocr import
- ocr export
- oracle local registry
ocrdump
- used to check ocr backup file
- oracle local registry
opatch
- patching grid control requires ROOT
crsctl
- Startup and Shutdown Oracle Clusterware, Oracle ASM and Database/Instance
- restore voting disk
- restore ocr
- set log for dynamic debugging
- check install periodically
srvctl
- modify nodeapps (ex. ip address change)
- add filesystem (acfs)
What solutions have people found so that RAC DBA can perform responsibilites yet not have ROOT password?In all the environments I've worked in, I either had direct su access with knowledge of the root password or used sudo. I really can't imagine an environment that would require something other than either of those two options.
In places with stricter auditing requirements we used sudo in conjunction with the sudosh shell wrapper to log all activities to syslog, but this was used by everyone and not just the DBA
Is SUDO the only solutuion? Every command need to be entered into SUDO config files that necessitates ROOT access.
As I demonstrated in the other thread, giving the oracle user sudo access to files that are writable by the oracle user (eg. root.sh) gives them the ability to access to a root shell. It is good to implement a "minimum privileges necessary" policy in your organization but it has to be within reason. The minimum privilege necessary for running and maintaining CRS is root.

Hi,
We are thinking about build RAC using ASM for OEM database. It'll have two nodes, oracle 10g and Hitachi san with solaris ( or linux ). I've few questions about RAC and ASM.
1) Do I need to have ASM instance running on each node ? ( most likely yes... but want to make sure )
2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?
I'm a newbie to RAC and ASM..

2) can I share oracle_home between ASM instance and database instance ? what is the best choice ?in 10g you can, in 11gr2 you cannot. and it might be better to seperate them because it will give you more flexibility with patching.
3) I'm planning to use shared disks for all files, all databases.... what are the pros/cons ?if you share your oracle_home you won't be able to do rolling updates. so i recommend to keep oracle_homes local.
4) what should be the installation procedure ? Meaning, first create ASM instance on each node, then install cluster software, build RAC databases...... can someone explain..follow the install guide for your respective version. for 10g you'd install clusterware first, then asm and database is last.
5) I believe RMAN is the only option for backup since I'm using ASM, correct ?pretty much. you could stop your database and dump the raw devices or use asmcmd/asmftp but rman is definitely the best choice

I have an apple id and it has my current email attached to it. however when i go to update apps it's asking for the password for an old email. I no longer have the old email and can't use it. when I go to icloud on my ipad it asks for the password for old email. it doesn't allow me to change the old email to current. when i go to reset it i can't remember the password or security questions for the old email so it doesn't let me go any further. How do I fix this? Do i need to call apple support?
I have the same problem - it is maddening. I rely on this iPad for work so this is not just an annoyance! The above solutions of changing the appleid on the device or on the website do not work.
The old email address no longer exists - I haven't used it in a year probably and I no longer have the account. I logged into the appleid website and there is no trace of the old email address so there is nothing that can be deleted or changed there. On the iPad there is no trace of the old email address so nothing can be deleted there either. I have updated the iPad software and the same problem comes right back. Every 2 seconds I am asked to log in using the old non-existent email. The device is currently useless.
The only recent change to anything was the addition of an Apple TV device, which was set up using the correct login and password.
Does anyone have any ideas? The iPad has been backed up to the iCloud so presumably it now won't recognize the current iCloud account? So restoring may notbe an option? -

Is there any number I can call to prove that I am the real owner of my itunes account so my girlfriend will be able to use her ipad to purchase new apps without having to go through the trouble of using one of my other apple devices? Random information: I believe my questions were set back in 2007 when I purchased my first ipod nano, since then I have used this same itunes account for my own ipod touch and ipad 2 and my girlfriends iphone 1st generation.
