Oracle 9i RAC GCM LAN on HPUX 11i

Hello,
I will install oracle 9i 9.2.x on hpux 11i,the system has two HyperFabric card,and I configure a two IP address for them,the IP address is 192.168.1.10 and 192.168.2.20,the relocational IP address are 192.168.1.11 and 192.168.2.21,and the host IP address is 132.198.155.72,but the oracle 9i document says:"Because the GCM is now integrated into the Oracle9i kernel, the GCM will use the IP
address associated with the default host name.", I do not know its meaning. should I configure the HyperFabric card address same as the host IP address of 132.198.155.xx? anyone has a real example of how to configure HyperFabric for Oracle 9i RAC on HPUX? the MC/SG OPS version is A.11.14. Thank you all.

The Fabric cards don't have IP addresses associated with them.

They are SCSI devices. Service guard(which I don't know) will handle the sharing of disk resources and all clustering issues. Since the disk on the disk array can be accessed through any fiber card, I don't think you have a problem there.

The IP address is associated with the NIC card.

Some advice concerning Oracle.

Patch the systems as completely as possible. Get the latest linker patches, December 2002 or later Quality bundle in.

Get your java and java patches up to date at http://www.hp.com/go/java

Tolerate no errors at all during installation. Stop, and make Oracle support resolve them on the spot. Don't take no for an answer. I let a seemingly meaningless error go by on a 9ias install and it has thus far put my project two months behind schedule.

Re: Oracle 9i RAC GCM LAN on HPUX 11i

Hello steven,
Thank you for your reply. I means the HyperFabric card will transfer HMP message,not the FC card connect to the storage. The HyperFabric is really need a IP address. It is the Heartbeat of Oracle,not MC/SG.

Re: Oracle 9i RAC GCM LAN on HPUX 11i

There is ip over fibre channel. I'll need the HBA part number to figure it out though.

There are also switch Ethernet ports used for SNMP traffic monitoring and management control messaging. These are large fabric networks with a gateway being used to bind the fabric. Refer to SAN Management and SES (* SCSI Enclosure Service *) or SNMP supported mibs, or establishing a telnet session.

IP addresses in MC/ServiceGuard are defined in /etc/hosts, either .rhosts or cmnodelist, cluster.ascii (* heartbeat ip *) and the package.cntl file. The last is for the floating ip assigned to the package.

Run 'cmscancl' which will indicate what IP's are being detected by the cluster and specify heartbeat or data LAN. In this file check for 192.168.1.10 and 192.168.2.20. Please attach.

RAC will load balance using IP's.

OPS uses shared volume groups that allow for simultaneous writes to the same vg from multiple oracle instances. And is overseen by HP-UX through LVM, Kernel drivers, SG for OPS and the application itself, Oracle.

Hello michael,
The card part number is A6386A,it is not Fibric Channel!Oracle 9i will use it to manage GCM.

Re: Oracle 9i RAC GCM LAN on HPUX 11i

I forgot to mention something important about ServiceGurad: Changing the IP's means making a new cluster.

Its the cluster binaries created with cmquerycl that binds the LAN together. And this process is not done through IP address but MAC address via the 'linkloop' command. So you'll also need the MAC if you've got IP changes going on. Use 'lanscan' and 'arp -a' and 'linkloop' to work with them.

Consequently, you'll be deleting your old cluster with 'cmdeletecl -C' and then remaking it with 'cmquerycl -C cluster.ascii -n node1 -n node2 ...', cmcheckconf -C ..., and cmapplyconfi -C ... Also means new packages.

Please respond if you need this proceedure for making new clusters and packages.

Hah!

Sorry for the confusion.

Found some links that'll be of assistance. The first indicates that HyperFabric can't be used as the heartbeat LAN, and also state its important to be patched up:

Re: Oracle 9i RAC GCM LAN on HPUX 11i

Hello Michael,
Thank you for your reply and your document link. I know how to configure HyperFabric on HPUX side,but I do not know how to configure Oracle 9.2.0.1.1 side, Could you please give me an example of how to configure oracle side to user HyperFabric network? Thank you.

Re: Oracle 9i RAC GCM LAN on HPUX 11i

Hello,

I am in a similar situation, where I need to configure HP HyperFabric card in a Oracle9i RAC environment. Has anyone successfully implemented the above kind of configuration? What should be the configuration from the HP-UX side(using UDP / HMP protocol) and how it can be specified in Oracle RAC, so that it can utilize the features of Hyperfabric card?

Thanks,

Abdul Salam

Re: Oracle 9i RAC GCM LAN on HPUX 11i

Hi Shigy,

Please refer to the document form metalink. It has step by step instructions for RAC setup on HP-UX and it have some information about Hardware (Private network connection ---HyperFabric.

I hope it will be helpfull.
