When preparing for a Oracle DB virtualization project…..

……read “Virtualizing Oracle Databases on vSphere” from VMware Press!

It is well written and managed to maintain my focus throughout the whole book. Probably one of the better books I have read on virtualization….9/10.

I am currently planning to virtualize a large Oracle database environment from an old HA cluster to a new VMware vSphere environment.

The book gives you loads of valuable information on what to look out for and different settings to give attention to. It also has a brilliant performance tuning chapter (but don’t thing this book will turn you into a performance tuning god) that gives you loads of stuff to help you maintain your performance while migrating over to your new fancy virtualized infrastructure.

The book will get a spot on my table until this project will be finished.

Interesting presentation on 3Par VVol support from HP

Hi,

Just read this presentation from HP on 3Par VVol support. I can’t really wait for vSphere 6.0 and VVols…this is a game changer – been thinking about NFS instead of block storage but this changes things somewhat since now we can do data services per VVol.

I am very interested in how this will affect backups.

The first rule when contacting HP Support ….grab a AHS log!

Yeah…just wanted to document this here for me. Hopefully you can make some use of it as well.

Before opening up a case with HP Support for HP Proliant servers (at least Gen8 and newer) make sure you grab a AHS support log. They will in 99.9% of cases ask for this log before doing anything. Also, if it is a blade server make sure you grab a “show all” from the OA.

The easiest way to get this is to download the log through iLO (at least possible with firmware 2.03 and newer). Go to Information -> Active Health System Log. Pick out the time range you want the log for and fill out the contact information and press Download!

Here is a guide from HP for alternative ways to get the log.

Brilliant new adblocker – µBlock!

Hi all,

I’ve just discovered new adblocker which seems to be way easier on resources then Adblock Pro (which is a brilliant tool in every other way).

Check out µBlock.

So far it seems that my resource usage on my laptop is about ~15-20% lower then usual!

Cool feature of Solaris IPS – Search for a CVE

Hi,

Just read a blog over at c0t0d0s0.org regarding searching installed packages by a CVE (Common Vulnerability and Exposures) number.

# pkg search -l CVE-2014-7187
INDEX ACTION VALUE PACKAGE
info.cve set CVE-2014-7187 pkg:/support/critical-patch-update/solaris-11-cpu@2014.10-1

VCP – Going for the gold!

Howdy all.

Finally, after working with VMware virtualization products for more then 10 years I am finally going for the VCP.

The course has been booked in April if I remember correctly but I was hoping to finish the exam before that. To help me out I have two books, Mastering VMware vSphere 5.5 by Scott Lowe and VMware vSphere Design also by Scott Lowe, Forbes Guthrie and Kendrick Coleman.

Lets see if I can cram and take the exam before April!

Configuring DNAT for Google DNS servers on Technicolor routers

Howdy all,

Stole the commands from: https://support.unlocator.com/customer/portal/articles/1501508-how-to-set-up-technicolor-router-for-chromecast

Add static routes for google dns servers Code:
nat mapadd intf=LocalNetwork type=napt outside_addr=8.8.4.4 inside_addr=192.168.1.254 outside_port=53 inside_port=53
nat mapadd intf=LocalNetwork type=napt outside_addr=8.8.8.8 inside_addr=192.168.1.254 outside_port=53 inside_port=53

save!
saveall

This will make sure all requests for Google’s DNS servers will be redirected to the router (which could have some other DNS servers, maybe some SmartDNS servers?).
