Getting ssh error while starting 10g cluster installation

Hi frnds
I am getting the following error while running 10g clusterware installation.Actually i done the ssh setup mentioned in the oracle doc.Generated both keys (rsa,dsa) on both nodes and copied these 2 files from both nodes to authorized_key file and copy this file to both nodes and ran $shell and ssh-add.Whenever i logs and run this SSH User Equivalency on node1(from where i run oui) and its persisting with other sessions but if logoff and logon i have to run the $shell and ssh-add to enable it.My dought is whether this ssh have to enable always or only while using OUI to install and applying patches cos this Equivalency dont need to run on second node correct ?

Hi
thnks for that but when i run that exec $SHELL and ssh-add again in one session i can do ssh it other sessions without any problem but if i logoff and login it will reset to back.Whether this ssh have to enabled on first node(where i run OUI) always irrespective of logons and logout or whether i have to start any services ?

OCS 10g Cluster Installation - Load Balancing

Hi all,
Anybody have sucessfully install and configure OCS 10g Cluster ?, with load balancing ?
I'm trying to install OCS 10g cluster with a two node server setup, and using Oracle web Cache as the load balancer, but not sucessfull. Any hints ?
Regards
Lanang

Just found out that Oracle Web Cache support HTTP and HTTPS only, no LDAP traffic yet. That why the cluster node installation failed. Trying using iptables NAT for the LDAP traffic, and the HTTP will use web cache.

Regarding Hangcheck timer configuration in Oracle RAC 10g r2 installation

Hi,
Is it necessary to configure hangcheck timer in Oracle RAC 10g R2 installation .
Can somebody guide when we should install the hangcheck timer in Linux oracle 10g R2.
Best Regards
Gupteswar Prasad Mishra
Edited by: Gupteswar on Jan 25, 2010 8:42 PM

yes, its recommended to configure hangcheck timer in RAC configuration
Configure the Hangcheck Timer
The hang-check timer is loaded into the Linux kernel and checks if the system hangs. It will set a timer and check the timer after a certain amount of time. There is a configurable threshold to hang-check that, if exceeded will reboot the machine. Although the hangcheck-timer module is not required for Oracle Clusterware (Cluster Manager) operation, it is highly recommended by Oracle.
cat /etc/rc.local
modprobe hangcheck-timer hangcheck_tick=1 hangcheck_margin=10 hangcheck_reboot=1

Hello,
Can any body provide me link for step by step 10g ASM Installation on linux (i.e from disk partitioning to final configuration). I searched on GooGle but didn't find ASM alone, though there were many step by step for RAC environment. I want to first learn ASM alone. Please help me as I'm first time learning ASM.

Regards,
AbbasiHi Abbasi,
It would be better if let me know version of Linux, how you plan to use the disk (direct or UDEV), RAC or Single instance.
Anyway, I'll assume you've using OEL/RHEL 5, UDEV for Single Instance (Oracle 10g installed) and only one disk (/dev/asm_disk1) configured for testing purpose.
Creating ASM instance on Linux (Single Instance) using DBCA
1. Add disk to Linux server
2. Configure UDEV for the device. E.g /dev/sdb -> /dev/asm_disk1 //check Oracle documentation for configure UDEV on RHEL/OEL 5. You can directly use /dev/sdc for testing purpose.
3. Change the owner of the disk. e.g. chown oracle:oinstall /dev/asm_disk1
4. As root user, run Oracle CSS script. The Cluster Synchronization Services (CSS) daemon provides cluster services for ASM, communication between the ASM and database instances, and other essential services
# $ORACLE_HOME/bin/localconfig add
5. As oracle user, run DBCA (X11 needed)
$ dbca
6. Select the "Configure Automatic Storage Management" option, then click the "Next" Button.
7. Enter a password for the ASM instance, then click the "Next" button.
8. On the confirmation screen, click the "OK" button to create the ASM instance
9. Once the ASM instance is created, you are presented with the "ASM Disk Groups" screen. Click the "Create New" button.
10. On the "Create Disk Group" screen, enter Disk Group Name of e.g. "DATA" and select the required level of redundancy.
•     External - ASM does not mirror the files. This option should only be used if your disks are already protected by some form of redundancy, like RAID.
•     Normal - ASM performs two-way mirroring of all files.
•     High - ASM performs three-way mirroring of all files.
11. If you didn't find any disk, click "Change Disk Discovery Path..." and enter "/dev/asm_disk1"
12. Select "External" for redundancy, tick the disk (/dev/asm_disk1) and click "OK" button.
13. On the "ASM Disk Groups" screen. Click the "Finish" button.
To access the ASM instance :
1. As oracle user, export the ORACLE_SID
$ export ORACLE_SID=+ASM
2. sqlplus "/as sysdba"
3. SQL> select name, total_mb, free_mb from v$asm_diskgroup;
SQL> select name, path, header_status from v$asm_disk;
To access the ASM command line utility:
1. As oracle user, export the ORACLE_SID
$ export ORACLE_SID=+ASM
2. Enter the asmcmd command
$ asmcmd

Please help me with this problem.
Thank you
Ravindran Kanniah

It is because of UNIX shell. I also faced this error during installation.
First check your shell by the following command.
$ echo $SHELL
Then select the below.
For csh shell
$ setenv DISPLAY 192.168.1.128:0.0
$ export DISPLAY
For sh,ksh and bash
$ DISPLAY=192.168.1.128:0.0
$ export DISPLAY
After you do this check the value of DISPLAY variable.
$ echo $DISPLAY
If the DISPLAY variable is set then run ./runInstaller.
One advice: Keep a complete log of your terminal session. This will help you in future :)

Oracle 10g R2 installation with ASM+RAC

Gurus,
Need some suggestuon on Oracle 10g R2 installation with ASM and RAC option.
We have found many documents on the Oracle, HP, HP-Oracle CTC and third party web sites, but nothing that is specific to this particular combination of separate
ORACLE_HOMEs, ASM and 10g RAC CRS. It is unclear for me from the documentation how this combination of ASM and 10.2g RAC may best be installed.
The high level steps i got after reading lot of docs as follows - but i am not sure whether these are correct or not. if they are correct, can any one share their experience/notes please?
1) Install CRS
2) Install RDBMS for ASM HOME - create separater oracle home for ASM instance using OUI
3) Install RDBMS for RAC Database Home - create separater oracle home for RAC database using OUI
4) Create ASM database using DBCA -
5) Use dbca to create database.

Oracle provides 'paint by numbers' tutorials called 'Oracle By Example'. (Go to OTN, check under the Training tab)
They have one for a Windows based ASM/RAC that you might want to review. Not your specific environment, but the steps will be dag-nabbed close.
I recommend walking the path (http://otn.oracle.com >> training:OBE >> Database 10g Release 1:VMWare:Installation
http://www.oracle.com/technology/obe/obe10gdb_vmware/install/racinstallwin2k/racinstallwin2k.htm

I had the same problem and solved it by doing the following:
Do not stop the DBCA to do this.
Go to Start->Control Panel-> Services -> oracleserviceyoursid and start the service. That will get you through that error.
Just in case you see this one as well....I did encounter a TNS error after that. I resolved this by commenting out (#) the line SQLNET.AUTHENTICATION_SERVICES=(NTS) in SQLNET.ORA file.

Cluster Installation - SQL 2005 / 2003 - Creating cluster group

Hi All,
I am working on the cluster Installation in our environment and facing some issues at the time of installing first node MSCS Installation. let me summarize the activities done so far
Environment Details
Physical Disk :
G: (Physical Disk - SAN )
I : (Physical Disk - SAN )
C: Local disk
Q: (Physical Disk Quorum - SAN )
F: (Database and logs)
-- > SCS installed locally in the server in G drive
Virtual Hostname and IP : SeparateIP & cluster1
Node 1: Hostname and separate IP
Node 2 : hostname and Separate IP
Installed MSCS service and tested the same - its working fine
Installed SQL 2005 database in cluster mode and its working fine
Started installing SAP
Step 1: Installation of SCS instance in node A (Used F drive) - Successfull Installed
Step 2: Installation of First node MSCS in node A
Here I am facing an issue, in the end phase of the installation it will ask for creating cluster group -- > There I need to define the Global disk as F (Which is defined at the time of installing SCS instance) - But i dont see that disk is available in the drop down box .
Is there any other workaround to bring the Global disk while creating the cluster group (First node MSCS installation)
Looking forward for your suggestions
Thanks and Regards
Vijay

Regret for the late update
112266 solved my problem and In my case, I have bisected the disk as two but in the cluster environment that should not be the case. Ensure the the same in disk management

ABAP+JAVA in Cluster installation

Hello gurus,
I've read all tha SAP HA documents and have noticed that in several cluster installation they split up
the ABAP SCS and JAVA SCS from the CI when installaing a double-stack system (ABAP+JAVA).
As much as I know, the SCS instances doesn't require a lot of memory or cpu, they are not the problem when there is a bottleneck (correct me if I'm worng ...).
So, what is the reason for splitting up the SCS isntances from the cluster group of central instance ?
Please advice,
Dimitry Haritonov

Hello Dimitry,
Basically the SCS instances determine the CI. Without having running message and enqueue servers, there is not a running NetWeaver cluster at all. So these processes together with the database and the global file system are critical for the cluster and its high availability. These are the so called single points of failures and need to be protected by the failover cluster. For more details refer to sections 2.2.4, 2.3.2 and 4.1 of "SAP WAS in Switchover Environments" technology handbook available at service marketplace.
You are right that SCS processes do not consume a lot of memory and cpu. They do not require a lot of time to start so for performance reasons it makes sense to split them from the ABAP and Java processes, which are much slower. If the SCS instances are installed in a separate cluster group than the whole CI, the switchover process will take less time.
I hope I answered to your question.
Best Regards
Vyara

Hi,
You know what ?
Step by step installation is different in every company because each company has a different usage of SAP software.
It is precisly your job as a SAP sys admin, to study the problem, to solve it and to write the step by step documentation.
In my company, it took me one month and my documentation is 250 pages long.
You will not get someone else doing YOUR job instead of you.
The standard SAP documenation is perfectly enough to study your particular case...
Good luck !

XREF best practices in ESB cluster installation-OESB10.1.3.3

Hi,
We are using Oracle ESB during last 2 years.
2 months ago I migrated our ESB installation to ESB Cluster in production (1 ESB DT, 1 ESB RT for polling
adapters, 2 ESB RT for further message processing).
We are using SOA Suite 10.1.3.3 with MLR#17 applied.
I faced a issue with XREF (populateXRefRow XPath function) in production system and need assistance.
All our ESB Processes contains next main parts:
1) Polling DB-adapter (or FTP-adapter, this didn't matter) that initiates a ESB process, routing service for that polling adapter
that asyncronously (!) invokes Requestor ABC level services (AIA terms);
2) Requestor ABC level-services perform XREF population and continues message
processing.
XREF population is doing with next steps:
we call lookupXRefRow XPath function, if value is not present in XREF, we doing
populateXRefRow call.
This logic is working fine when we are not using ESB cluster, but now step 2) (ReqABC level) is performed by different ESB servers
and frequently we faced unique constraint violation error on XREF_DATA
population (during populateXrefRow call).
ESB RT nodes using to balance load but transmitted data is intersected. For example, we are poll not documents but document details instead (polling table populated by Oracle Streams, there are no guarantee that document header receives earlier than document details, because our system is high loaded and we are using commit_serialization=none with parallelism at APPLY processes).
Each ESB RT instance can receive different rows of same document and xref population done at document header level.
My question is: what is best practices to work with XREF in ESB cluster installations?
May be other peoples faced with this issue and how this issue was resolved?
I know possible workarounds to accomplish this task: not call populateXRefRow function in XSLT, instead call PL/SQL procedure or function that working same but can ignore any exceptions.
This's solution not liked to me, but I dont know any other solutions.
Also I cannot not populate XREF because XREF actively used in inter-systems communication.

Private interconnect of an Oracle 10g cluster

Can you please answer below questions?
Is a direct connection between two nodes supported on the private interconnect of an Oracle 10g cluster?
We know that crossover cables are not supported, but what about a Gigabit network with a straight cable?”

Hi,
I really wouldn't suggest that approach, It is definitely not efficient and not flexible
- If you have 4 nodes, and nodes 1 want to send message to node 4, the package must go through node 2 and 3? Is it efficient? NO absolutely
- If you have e.g 2 nodes, if one of the link down in one of the nodes, the other nodes link will also down, this will most likely evicting both nodes instead of one node
- your clusterware nodes iis limited by the cable which is not efficient
- etc etc etc more disadvantages than advantages

Oracle 10g database installation in red hat 5

what are the packages needed for oracle 10g database installation in red hat 5?
what do you mean by yum way of installation?

Check on the release notes for your platform
This is for x86-64 Linux.. read it all, then you'll find the "6 Documentation Corrections and Additions" section you'll find the RPMs that you need
http://download.oracle.com/docs/cd/B19306_01/relnotes.102/b15666/toc.htm
then go to the official doc installation of 10gR2 on x86-64 Linux
http://download.oracle.com/docs/cd/B19306_01/install.102/b15667/toc.htm
Yum is a package management tool. This is what you'll be using to install the RPMs. But first you'll have to setup the Yum repository, usually what I do is stage the DVD media on the server then make it as a repository. If ever there's a specific (higher) version that I need then I just pull it on the RedHat Network.
There are a lot of HOWTOs about Yum. You may read on this link http://docs.fedoraproject.org/yum/en/
