Confio software is hosting a live discussion on twitter tomorrow Tuesday April 15 at 12pm PST on the subject of Oracle performance.
I’ll be online answering performance questions and have invited many other friends to participate. Some friends who’ve said they’ll be there are
Participation and tracking of the discussion can accomplished by either posting with and following along with the #datachat hashtag.
Maximum manageable storage per VM by ESX version
- 4.1: 32TB (vmdk) / 120TB (RDM)
- 5.0: 60TB (vmdk) / 3.75PB (RDM)
- 5.1: 60TB (vmdk) / 3.75PB (RDM)
- 5.5: 3.63PB (vmdk) / 3.75PB (RDM)
Note that the 60TB limit for 5.0 and 5.1 requires Update 1. Without this the limit is 24TB.
Exceeding the limits on ESX < 5.5 can result (more...)
Unfortunately, what Oracle calls “Network Waits” have little to do with Network but and almost exclusively to do with the time it takes to pack messeges for the network before they are sent.
Client = you, the tool, sqlplus, application
Not the client, the other side = the shadow process is communicating to the client
Of the three waits, only “more data” is possibly related to network issues and that’s not even clear, the (more...)
The demand for healthcare application development is exploding and has been exploding over the past couple of years because of
- Obama Care – Affordable Care Act
- Regulatory – HITECH and HIPAA Privacy Acts
- IDC 10
- Pro-active Health Care (versus reactive health care)
- Mobile devices
but to develop applications for health care requires the data to be masked. Why does masking data matter and matter especially for health care? If patient information gets out it can (more...)
This is super cool, fine grain powerful performance analytics in Delphix 4.0 just released!
To understand what the analytics shows, it is important to understand the role Delphix plays and where Delphix sits in the architecture of data. Delphix is used to provide clones of a data. The most well know Delphix data cloning example is the use case of cloning Oracle databases. If I had three normal copies of an Oracle database, then (more...)
The new Oracle Scene magazine is out. Checkout pages 48-50 for an article by me.
Here are the awesome contents of Oracle Scene magazine Spring 2014:
- THE UPGRADE UPHILL CHALLENGE by George Wilson 12
- READING EXECUTION PLANS by Jonathan Lewis Ace Director 18
- ANGELS IN THE ARCHITECTURE by Chris Muir & Frank Nimphius 28
- PROCESSOR GROUP INTEGRATION IN ORACLE DATABASE 12c by Nikolay Manchev Ace 42

- APPLICATIONS TRANSFORMATION:
Linux is taking over the workloads from the shrinking market share of
- IBM AIX pSeries
- Solaris Sparc Servers
- HP-UX Itanium
because Linux provides a reliable and less expensive platform. The costs reductions per users according to IDC for using Linux over UNIX can be on the order of 1/5 the price per end user
Legacy RISC Systems Cost $1,425/User versus Linux at $ 256/User
- IDC 2012
The LINUX systems will represent the marjority of the (more...)
Delphix is amazing technology. I’ve been at Delphix for almost 4 years. The first year I was at Delphix was the first year Delphix was released on the market. Even from that first release Delphix revolutionized how we managed and think about data. Data goes from an onerous massive burden to instead a fast, easy, powerful resource. As one customer put it data goes from being your enemy to being your friend (and a powerful (more...)
