Is ASM necessary for 11gr2 crs install ?

Hi,
I am about to install 11gr2 CRS (now grid ?) on Oracle E Linux 5.6.
I have been doing research and it is not clear to me.
Question 1) Is ASM mandatory as part f the install ? (I would prefer not to install ASM and just use OCFS2 for the database files).
Question 2) Can I use OCFS2 for a common location for the software binaries as well ?
Thanks,
Shawn.

Question 1) Is ASM mandatory as part f the install ? (I would prefer not to install ASM and just use OCFS2 for the database files).No,
Question 2) Can I use OCFS2 for a common location for the software binaries as well ?Yes, upgrade OCFS2 to at least version 1.4.1

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

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,

If you're NEVER going to EVER open a PDF, then no, it wouldn't be necessary. But you're going to be in an extremely rare set of circumstances if that's going to be the case.
Otherwise, you'll need it, and Reader 11 works with XP Pro.

PageComposer Error - Cannot find the module necessary for printing C5051

Hi
Having some problems trying to setup a Windows 2008 R2 print server with shared Canon iR C5051 printer
I've created the printer, installed the 64 bit driver Canon iR-ADV C5045/5051 PCL6 v 20.90 and works fine for 64 bit Windows 7 clients, installed the 32 bit driver by selecting printer properties, sharing tab, additional drivers and selecting x86 and pointing to the 32 bit PCL driver. Driver installs fine on the print server without any errors.
Goto 32 bit client, add printer, select the shared printer from the printserver, printer installs Ok. When the user however tries to print, get the error:-
Canon PageComposer
Cannot find the module necessary for printing
Re-install the printer driver
I've done this countless times, any idea's on how to fix ?
Thanks

Where is the code you posted? Running in a separate project, I assume? Does that project have a dependency on the project containing the app module specified?
And just to check (although by default, JDev should do this for you)--the app module project has been compiled since adding the configuration, right? You need to check to make sure the config exists not only under Project/src, but under Project/classes.
Edited by: Avrom Roy-Faderman on Oct 6, 2008 2:02 PM
Oh, and BTW--I assume this is not a typical ADF application, right? In a standard ADF application, you would very rarely need to instantiate an application module in code like this; you could just let the data binding facility do it for you. The technique like the one you're using is most appropriate for purely programmatic, no-UI cases. (e.g., once I tried to implement an SMTP server backed by business components. That was an appropriate case for ditching databindings and doing the sort of thing you're doing, because it had no view layer (because it had no UI to render).

Suggestion for installing 11gr2 crs with existing 10g crs...

Hi, I need suggestions on installing 1120 rac on suse 11 where already 10g rac with asm is running. I need to upgrade the 10g crs and asm while installing 11g crs. Pls share your experience on these
1- what are the challenges to run 10g database on 11gr2 crs? is this suggested?
2- challenges to upgrade asm and crs to 11gr2.
3- can we use 2 asm instance in 11g grid infra to manage 10g and 11g db separately.
4-what could be back strategy for this kind of setup? RMAN?
5-how many extra ip i need to install 11g crs with existing 10g crs . we plan to use 3 ip for scan.
Also if possible please share any doc for this kind upgrade
Thanks,
Abhai

1.) Yes this is o.k. Just see this MoS Note:
Pre 11.2 Database Issues in 11gR2 Grid Infrastructure Environment (Doc ID 948456.1)
2.) Well first only clusterware is upgraded. You will be asked if you want to upgrad ASM, but this is not mandatory at first.
You can use ASMCA later to switch ASM from 10.2 to 11.2 (this does not have to be done during upgrade).
3.) No you can only have 1 ASM running. So it is either 11.2 or 10.2 ASM. (However I suggest 11.2).
However you can/should have multiple diskgroups. One data and fra for the 11.2 databases where you set the rdbms.compatibility to 11.2 to use the new features, and one data an fra diskgroup for the 10.2 databases.
4.) As long as the compatibility setting of a diskgroup isn't changed, you can always switch ASM back to use 10.2 executables. (Just do a srvctl remove asm and add ASM).
Search this forum - there has been another thread about this.
Regarding fallback of clusterware => See installation guide.
5.) Mandatory are just 3 additional IPs for the SCAN.
Upgrade documentation see the installation guide of 11.2 GI.
Upgrade for ASM see Storage Admin Guide.
Upgrade to move OCR and Vote to ASM see Clusterware Admin Guide.
Upgrade to database see Database Upgrade Guide
Additionally look in MoS for the Upgrade Companion.

Creation of ASM disk for OUI

I need to install a Oracle Database in order to install Enterprise Manager Cloud Control 12c.
Need the database to use a ASM disk.
I used the following command to create the disk, per the Oracle Database Installation Guide.
#/usr/sbin/oracleasm createdisk DISK1 /dev/sdd1
#oracleasm listdisks
DISK1
However, when running the OUI for Oracle Database 12c (understand 11.2.0.3 is certified for Cloud Control), step 7
errors INS-30517 when attempting to select "Oracle Automatic Storage Management" for "Storage type".
Researched the error at this location but no cause or action was provided.
http://docs.oracle.com/cd/E16655_01/server.121/e26079/common_errormessages.htm
INS-30517: Automatic Storage Management software is not configured on this system.
The database install guide states that I need to ensure the "disk discovery string" is set the "ORCL:*" or is left empy ("") so the installer discovers these disks.
It doesn't show how to confirm or change the settings.
At this point I'm at a stopping point.

All ASMLib installations require the oracleasmlib and oracleasm-support packages. The oracleasm kernel driver is included in the Oracle UEK kernel. Perhaps you are missing the oracleasmlib package. You can download it from:
Oracle Linux: Oracle ASMLib | Oracle Technology Network
Oracleasmlib is not necessary for ASM to work, but it contains software necessary for Linux oracleasm, including the /usr/sbin/oracleasm-discover utility, which the Oracle installer used in the previous 11g version to detect available ASM volumes.

Need 11gr2 RAC install Guide on Solaris 10 x86 using containers and NFS

I'm looking for an 11gr2 RAC install Guide on Solaris 10 x86 using 2-3 containers. I need to have the NFS server reside in the global zone or on a 3rd container visable to the two rac containers.
Please share me installation guide!
Thank you!
PS - I currently have run into an install issue -
Can't change ownership on /oracle/products/11.2.0/ocr/: not owner at /oracle/app/11.2.0/grid/crs/install/crsconfig_lib.pm line 5014.
I suspect the NFS share params from the NFS server in the global zone are not 100% correct to the two rac zones/containers.

Have you visited Oracle Support Services website (formerly metalink) to determine if your desired configuration is supported?
Last time I looked it was not.
That said Oracle database installation guides are fully documented online.

Can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

can any one say that list of hardware for 11gr2 2node rac installation? thank in advance

Hi ,
Hardware Requirements
Physical memory (at least 1.5 gigabyte (GB) of RAM)
An amount of swap space equal to the amount of RAM
Temporary space (at least 1 GB) available in /tmp
A processor type (CPU) that is certified with the release of the Oracle software being installed
A minimum of 1024 x 786 display resolution, so that Oracle Universal Installer (OUI) displays correctly
All servers that are used in the cluster must have the same chip architecture, for example, all 32-bit processors or all 64-bit processors
Adequate disk space in the software installation locations to store the Oracle software
You need at least 5.5 GB of available disk space for the Grid home directory, which includes both the binary files for Oracle Clusterware and Oracle Automatic Storage Management (Oracle ASM) and their associated log files, and at least 4 GB of available disk space for the Oracle Database home directory, or Oracle home directory.
About Shared Storage
These Oracle Clusterware components require the following disk space on a shared file system:
Three Oracle Clusterware Registry (OCR) files, 300 MB each, or 900 MB total disk space
Three voting disk files, 300 MB each, or 900 MB total disk space
If you are not using Oracle ASM for storing Oracle Clusterware files, then for best performance and protection, you should use multiple disks, each using a different disk controller for voting disk file placement. Ensure that each voting disk is configured so that it does not have share any hardware device or have a single point of failure.
Network Hardware Requirements
When you configure the network for Oracle RAC and Oracle Clusterware, each node in the cluster must meet the following requirements:
Each node must have at least two network interface cards (NIC), or network adapters. One adapter is for the public network interface and the other adapter is for the private network interface (the interconnect). Install additional network adapters on a node if that node meets either of the following conditions:
Does not have at least two network adapters
Has two network interface cards but is using network attached storage (NAS). You should have a separate network adapter for NAS.
Has two network cards, but you want to use redundant interconnectsIn previous releases, to make use of redundant networks for the interconnect, bonding, trunking, teaming, or similar technology was required. Oracle Grid Infrastructure for a cluster and Oracle RAC can now make use of redundant network interconnects, without the use of other network technology, to enhance optimal communication in the cluster. This functionality is available starting with Oracle Database 11g Release 2 (11.2.0.2).Redundant Interconnect Usage enables load-balancing and high availability across multiple (up to 4) private networks (also known as interconnects).
However, When you install Oracle software, Oracle Universal Installer (OUI) automatically performs hardware prerequisite checks and notifies you if they are not met.

Pradeep. V
