[Linux-cluster] Question with RHCS and oracle

[Jankowski, Chris]

Marcelo,

You can use standard RHEL CS manuals as a starting point:

Red_Hat_Enterprise_Linux-6-Cluster_Suite_Overview-en-US.pdf
Red_Hat_Enterprise_Linux-6-Cluster_Administration-en-US.pdf

Remember that you still need to have shared storage, which in enterprise class systems means FC storage arrays or at least iSCSI based arrays.  Both require proper configuration to achieve full redundancy of access. For FC this means configuration of device mapper multipath. There is RHEL manual for this as well.

Then you probably would like to use LVM for your storage.  There is a little known and badly documented way of using LVM with tags.  You probably want that.

Then you layer either ext4fs or XFS on top.
No need for GFS.  You just do not install it. Nor do you need CLVM.

Regards,

Chris Jankowski

HI
Chris, thanks for your repply.

I was reading the Lon's notes, I have seem that he uses a active-passive conf, without gfs. I installed a mysql cluster, but, I used gfs. If I use and active-passive conf, I believe that I shouldn't use gfs. Anyone could explain me how to configure a cluster without gfs?.
Thanks.!

Marcelo,

The paper you mentioned is now 6 years old.  Quite a bit has changed in RHEL  CS and Oracle DB since.

If you need RAC and you are doing this for a living, I recommend that you invest in these two books:

For Oracle 11g (published in 2010):
http://www.amazon.com/Pro-Oracle-Database-11g-Linux/dp/1430229586/ref=sr_1_1?s=books&ie=UTF8&qid=1303262530&sr=1-1

For Oracle 10g (published in 2006):
http://www.amazon.com/Pro-Oracle-Database-11g-Linux/dp/1430229586/ref=sr_1_1?s=books&ie=UTF8&qid=1303262530&sr=1-1

Each has 800+ pages of very solid information.

However, as always with books, they are obsolete the day they are published.  Oracle 11g R2 RAC is covered in the first book in one chapter only.

I hope this helps,

Regards,

Chris Jankowski

Thanks for your reply. I 'll research how install RHCS with an active-pasive cluster.
Regards!

If you want an active-passive cluster, that is fine to do just with
RHCS, no requirement for RAC. The RH docs have an example of how to do
an oracle cold-failover cluster for oracle.

If you want active-active then you will require RAC.
