Through a teach back session, in a matter of an hour, I got to hear from them, all that they learned in five days time. Their performance was captured and that's what you see below:
I'm certain, some day or the other, there'll be a part 2 for this story.

Meet my new friends. Majority of them belong to Kenya. With India joining the Emerging Market, an announcement you can read in big boss's blogs, I might get to meet more such folks in the days ahead. They learned Cluster and taught me back some words in Swahili, their National Language. I ain't bad at picking up lessons, for you would now hear me say, "Siku njema"

There was an interesting observation on day 02 of this training program. I am mentioning it here, firmly believing that it would be one useful piece of information to someone wandering around in the blogosphere. During the process of Cluster Installation, while the second node in a two node-cluster was being configured using the scinstall command, precisely at a point when the cluster name was specified, the configuration kept failing. Upon running the snoop command specifying the hostnames of both the nodes, the following error was spotted:
sunc6 -> sunc5 PORTMAP C GETPORT prog=100145 (?) VERS=1 proto=TC
sunc5 ->sunc6 RPC R (#140) x10=1209249015 can't authenticate (unknown cause)
Thanks to the internal edition of sunsolve, we figured out that we could eliminate this error, magically, by changing the property config/local_only of the Solaris 10 Service rpcbind (FMRI: svc:/network/rpc/bind) to false.
svc:> select network/rpc/bind
svc:/network/rpc/bin> setprop config/local_only=false
# svcadm refresh network/rpc/bind:default
# svcprop network/rpc/bind:default | grep local_only
Things worked and I was happy about that. But then, how did this property (config/local_only) changed to true, allowing only local connections, in turn resulting in the configuration error during cluster installation? On the same day, at night I reviewed the Security By Default Design in Solaris Operating System and very soon realized that all such properties - like the one mentioned above in this paragraph - are set to true if one chooses NOT to enable network services for remote connections, a question that is asked while the installation of Solaris 10 Operating System. All was very clear. Let me leave you with an additional information revolving on the topic above: When one chooses to disable network services for remote clients in Solaris OS, the profile named generic.xml would be a symbolic link to generic_limited_net.xml found under /var/svc/profile, whereas if it is enabled, then generic.xml would be a symbolic link to generic_open.xml profile in the same directory. To know more about it, click here.
I'm taking the same course next week. Unlike the 99.999 % uptime expected from a Solaris Cluster set up, my job permits me a 'downtime' during the weekend and I really hope to have a peaceful and productive weekend. Wishing you all the same.

But before all that, check out the batch photograph of AM 3480 class concluded on 01/Feb/2008, here at Hyderabad.
Thanks folks for the lunch on the final day; more so for choosing Sun. Wish you all good luck!

A couple of weeks back I could seize the opportunity to meet up with the Senior Product Manager of Access and Federation Manager and got to know from him the immense progress that the Engineering team is making in improving upon the features of the products. Frankly, it is a nice time to be a part of these positive developments in the software portfolio of Sun.
Last week I met up with some nice folks from various organizations, who had come down to Bangalore from different locations to learn IDM 345. Most of them have positive feedback about this course and some of them are in fact looking forward to take up the advanced training on IDM viz IDM 4484. As of this writing, the course IDM 4484 is based on 5.5 version of Sun Java System Identity Manager. I am told that the IDM 4484 course based on the 7.0 version of Identity Manager is in the pipeline and is likely to be released soon.
I am traveling to Mumbai this evening to start a training on Access Manager tomorrow. So let me get out from here and start preparing for my journey, but before that meet my new "IDM friends"
