About year ago or more, Oracle came out with a way create thin clone copies of a database in EM 12c called “Snap Clone”.
Not sure this makes working with data any sunnier and certainly doesn’t add any sunlight to the cloud movement. Snap Clone technology has seen little adoption AFAIK. I’m not aware of a single customer reference yet. Why ? Because Snap Clone doesn’t solve the real problem. Snap Clone is complex, depends on cobbling other technologies together, (more...)
Performance testing requires full, fresh data
Many organizations don’t even attempt to test performance until very late in their development cycle because it is only in the UAT (or equivalent) environment that they have a full copy of their production data set. Errors and inefficiencies found at this stage are expensive to fix and are often promoted to production due to pressures from the business to meet release schedules.
Delphix customers give each developer, or (more...)
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...)
