-bash: fork :resource temporarily unavailable

I was getting -bash: fork :resource temporarily unavailable on of the ESX host. I was not able to issue reboot/vmotion or anything with this ESX host.
I found huge memory error under hostd log

It was indication that service console is running out of memory. I checked my service console and it had 272MB. I looked at messages and found that HPSIM related messages.

I have recently deployed HPSIM on these ESX host. In the past I do know that HP SIM agent can create lots of problem

Deploying windows using MDT and WDS

For a while I was working on solution for deploying windows using WDS (Windows Deployment service ) and MDT (Microsoft Deployment Toolkit.). I came across many interesting issue everyday.
Like you should have desperate VLAN for server build purpose. Only this server should have "iphelper " enabled.

Going forward I will keep sharing my experience with MDT and WDS

SUN-ORACLE deal: Capitalist strikes again

Many blogs and article were busy understanding the deal and justifying it, who has win-win situation. How Oracle will deal with this buyout? How Oracle will be benefited with this deal? How Jonathan/Larry would be run their business? But no one talks about why SUN landed up in situation like this ? Did they put any effort to come out the situation like this? How Jonathan can transform the business of SUN to save his company?

But no what is the point to think, they have already milked the cow. Now cow is grown old and does need it any more. Well people may tell me that it was not worth to put any effort to save the company as regulator and shareholder were in favor of this deal. I agree because no business man in this world is for Charity . They do when they are looking for some government subsidies or when they feel that their popularity is going down. I may sound pessimistic but I can bet % of these business man do because of reason state above.

When I compare these MNC with Indian MNC I find that they are little bit for passionate about their company/business/employee (I may be wrong). I read that these Indian MNC are still honoring their offer given to collage pass out. They are not putting paper napkin/toilet paper inside toilet (I really don’t care and I can manage with handkerchief) .They are not giving any increment and also all the hikes are freeze (Which is fine as long as I have my job). We should be proud because they have shared their profit with us so we should be with them during the time of crisis.

I was wondering Jonathan given thought about something like this? SUN hardware is one of the costliest one, so what did they do to bring down the price. I guess NONE. So now Jonathan and team will get share after this deal. He and his family will have luxurious life, who care about employee’s grief. They are senseless creature. I have one of my friend who is part of Sun family and after looking at his agony I realize how painful it is to be part of MNC. He has been loyal servant of SUN and this what he got in return. Jonathan don’t have any emotion attach to his company and their employee? I feel that bringing up a company is similar to bringing up your own kid. You go through same pain and pleasure when you see kid/company grows. How can you just sell the company and enjoy the billions of dollar? Do you sleep on those dollar if yes do you get good sleep by devastating your own families (Remember employee are as good as your family member )

Operation Lotus completed

Operation Lotus completed successfully today. Today India being world largest democratic country going through electoral phase to elect their government and I along with family casted their vote for the same reason. After casting my vote I got a feeling that “YES I have done something for the country”. Yeah I have casted my vote after a long gap because of various reason. Whom I voted for ? off course for BJP and not only me but my wife and brother also voted for BJP. Well people debate because of media influence terming them as communal force and other party as secular party. Well all the political party in India is one or the same but just their level are different. And to my view BJP level is little bit lower than other party. Party which focus is just not to grab the PM seat but also to protect implement Hindutav. Now this communal and Hindutav definition to such extend by this media that people now understand as a big drawback for India. Well Hindutav is not just Hinduism but is also talk about our culture and I don’t think there is nothing wrong If I say I want to protect Hinduism +our culture. I told I will follow hindutav and I did not told that I will devast muslism or christanism . When I say I will protect Hinduism I had been termed as communal why ? Well this is all Media which control peoples mind and I don’t care what people want to term me as but I will always follow BJP.

Change/Sync Harware clock with NTP on ESX host

My few hosts are spread across Australia it has major issue with H/W clock and local clock.
[root@xxxx]# hwclock --show
Sun 28 Sep 2008 10:03:23 PM EST -0.804718 seconds
[root@xxxx]# date
Wed Apr 15 22:33:50 EST 2009

In order to fix it use following command

hwclock --systohc –localtime

I cannot resist to cut and paste the following from this url

1. Make sure /etc/sysconfig/clock has the proper settings. For me this is:
ZONE="America/Chicago"
UTC=false
ARC=false
This modification properly sets the system during the boot process in the init scripts.
2.Run the following command:
ln -sf /usr/share/zoneinfo/America/Chicago /etc/localtime

Substitute "America/Chicago" for the proper time zone setting. When you run the date command, you should now see your time presented with the correct timezone "indicator"

[root@SMHESX01 root]# date
Tue Jun 21 23:45:03 CDT 2005

3. Set your hardware clock to match the current time:
hwclock --systohc --localtime

4. Verify hardware clock with:
hwclock --show
Tue Jun 21 23:49:36 2005 0.956810 seconds

You can change to any time zone I want using this method and the time/date change based on timezone configured.

5. You may also want to toss the following in for good measure:
ntpdate ntpserver.domain.com
