This series of blogs has been exploring several aspects of Cloud computing which have the difficult property of orthogonality – a characteristic where two aspects of Cloud computing which would seem to work together actually follow separate and sometimes divergent paths. The tangible result of this orthogonality is difficulty coming up with an accurate assessment for a Cloud computing offering, since these multiple areas are not (more...)
It’s the nightmare every C-suite exec envisioned back when talk of doing social media first started…what happens if the brand makes a catastrophic and very public social media mistake? Don’t people realize how much money has been spent on marketing and PR to make sure every syllable the brand puts out is soft, safe and sanitized?
Social is 24/7, real-time, revealing, and involves interaction between humans. That is not a recipe corporations seek out. But (more...)
Among the blog posts, articles, events, and other items shared with the more the 5,000 fans of the OTN ArchBeat Facebook Page over the last seven days, the following items were the most popular:
- OIM Clustering: Keeping separate environments separate | Simon Kissane
For testing and development purposes, it is common to have multiple distinct OIM environments co-existing on the same subnet. In that scenario, it is essential that the distinct environments utilize separate multicast (more...)
When people take on home renovation “Do-It-Yourself” projects beyond their skills, disaster ensues. Apparently, this is so common that you can base a whole TV series on this theme – where professionals rescue the disastrous DIY project for the grateful and clueless amateur handyman.
I’ve seen the same thing happen in many IT projects. The people in the organization overestimate their own skills and are unable or unwilling to pay the cost of professional external (more...)
Everyone “knows” that bitmap indexes are a disaster (compared to B-tree indexes) when it comes to DML. But at an event I spoke at recently someone made the point that they had observed that their data loading operations were faster when the table being loaded had bitmap indexes on it than when it had the equivalent B-tree indexes in place.
There’s a good reason why this can be the case. No prizes for working out what it is – and I’ll supply an answer in (more...)
Opinions vary on the relationship between service oriented architecture and cloud computing. Some say SOA is essential to the cloud. Others say cloud is entirely possible without SOA. In this three-part program three members of the Masons of SOA, the group behind the Industrial SOA article series, offer their insight into the issue.

I think of myself as a developer, but my current role is in a small team running a small system. And by running, I mean that we are
- 'root' and 'Administrator' on our Linux and Windows servers
- 'oracle / sysdba' on the database side,
- the apex administrator account and the apex workspace (more...)
We have been migrating our databases from the non-Exadata servers to the Exadata Database Machine using the “RMAN 11g Duplicate standby from Active database” command, to create the standby databases on the Exadata machine. Below are the steps which were performed for these successful migrations. Assumptions Here we assume that the following tasks has been […]
If you haven’t talk to me IRL for the past 10 months, then I haven’t pestered you about the wonders of BLE and micro-location. My love affair with BLE (Bluetooth Low Energy) beacons became clear when I heard at WWDC 2013 that Apple was implementing BLE beacon detection in their CoreLocation framework. Apple showed how a small BLE beacon sending a constant signal (UUID + Major + Minor *) at a given interval could help (more...)

Replication of data is always a fun thing to look at; What is replicating?! Discussions around, How do I get data from server/database A to server/database B or even to server/database C are valid questions and are often asked by management. Often the simple (knee jerk) answer is, just set it up and start replicating. Although Oracle GoldenGate may be simple (for some architectures) to meet the demands of management and the (more...)

This is the fifth article in a series called Operationally Scalable Practices. The first article gives an introduction and the second article contains a general overview. In short, this series suggests a comprehensive and cogent blueprint to best position organizations and DBAs for growth.
We’ve looked in some depth at the process of defining a standard platform with an eye toward Oracle database use cases. Before moving on, it would be worthwhile to briefly touch (more...)
I caught up with my clients at MongoDB to discuss the recent MongoDB 2.6, along with some new statements of direction. The biggest takeaway is that the MongoDB product, along with the associated MMS (MongoDB Management Service), is growing up. Aspects include:
- An actual automation and management user interface, as opposed to the current management style, which is almost entirely via scripts (except for the monitoring UI).
- That’s scheduled for public beta in May, (more...)

I regularly read threads on the oracle-l mailing list, and occasionally feel very tempted to reply to one. Just recently I saw one that I liked a lot. It is specifically about using an Oracle Database Appliance (ODA) as a Disaster Recovery (DR) solution for an Exadata system. The Exadata configuration was not specified, I assume it was a smaller (eighth rack/quarter rack) configuration.
There were lots of arguments pro and against that Exadata->ODA architecture, (more...)
