Oracle RAC On SLES 10
I am stuck in RAC installtion on SUSE 9.
it has 2 nodes and the node on which I am mounting ocfs2 filesystem it has
Checking heartbeat: Active
and other has
Checking heartbeat: Not active
when I am mounting the file system on second node it says
mount.ocfs2: Transport endpoint is not connected while mounting /dev/sdb1 on /oravl06_RAC
the only issue I could spot is port 7777 is closed on one server and open on other.
My question---
is this really related to port setting or something else.
How to open a port in SUSE?
whats should be the entry in services file for this port
7777/tcp open XXXX

Re: Oracle RAC On SLES 10
You could check with:
/etc/init.d/o2cb status
All information you need is in:
/usr/share/doc/ocfs2-tools-*/README.O2CB
Maybe the path is different for documentation in SUSE.

Re: Oracle RAC On SLES 10
everything seems to be fine in status, except heartbeat
# /etc/init.d/o2cb status
Module "configfs": Loaded
Filesystem "configfs": Mounted
Module "ocfs2_nodemanager": Loaded
Module "ocfs2_dlm": Loaded
Module "ocfs2_dlmfs": Loaded
Filesystem "ocfs2_dlmfs": Mounted
Checking cluster ocfs2: Online
Checking heartbeat: Not active
on the server where ocfs2 is not mounted.
I am not sure if its like this is this should be Active on both nodes.
I also feel somep problem with interconnect but could not figure out whatexactly is the scene.

Re: Oracle RAC On SLES 10
Example:
node1>
Checking O2CB cluster sfx: Online
Heartbeat dead threshold: 31
Network idle timeout: 30000
Network keepalive delay: 2000
Network reconnect delay: 2000
Checking O2CB heartbeat: Active
node2>
Checking O2CB cluster sfx: Online
Heartbeat dead threshold: 31
Network idle timeout: 30000
Network keepalive delay: 2000
Network reconnect delay: 2000
Checking O2CB heartbeat: Active
Check your ocfs2/cluster.conf and identify the ip_address configuration on both nodes.
Ensure that you can ping that ip address from each one.
Use the ethtool command to identify if your private adapters have link.

Re: Oracle RAC On SLES 10
The only issue I can feel is of port cause in one server port 7777 is open on other its closed.
What are the entries should be there in /etc/services file.

grep -i o2cb /var/log/messages*
On both nodes.

I would take a look into that init script and see what this "Checking heartbeat" does. My best bet is that it checks the port 7777, but I'm not sure as I don't know RAC environment in SuSE very well.
Unix operates with beer.

Re: Oracle RAC On SLES 10
That means that is inactive because you cannot mount the ocfs2 filesystem. We must find the reason of this.
Try with egrep "e2|ocfs2" /var/log/messages*
I have seen a problem similar searching and it was caused by different versions of ocfs2 installed on the nodes. Check the versions on both nodes with rpm -qa | grep ocfs
