Friday Philosophy – Do Average to Be a Success

A few days ago a friend of mine, helifromfinland, tweeted something that exactly matched the topic that I was thinking of doing my next Friday Philosophy on. Heli said:

I am learning to do things well enough, not always perfect. Even writing that sentence feels so wrong but #babysteps :-D

That made me smile – I know the feeling myself and I know some people for whom it is all-consuming. It is something that I suspect many people who are active in the oracle community struggle with. We all try and do the best we can at all we do.

In our jobs in I.T what is needed most often is not the perfect solution – or even the best solution we can come up with. It is:

The best solution that achieves the requirement within the timeframe allowed.

Getting Psyched for Collaborate 2015

It’s that time again. Collaborate 2015 is fast approaching and, I have to say, I’m pretty damn psyched! This is the first time my personal company, NEXTGRES, will be demonstrating its game-changing database compatibility features to Oracle DBAs, developers, and users. I’d love for anyone reading my blog to drop by, whether it’s just to say “hi” or to see […]

Remote graphical installs

Most of my servers tend to be Linux VMs on VMware ESX without any graphics desktops setup, so it can be disconcerting trying to install Oralce with it’s graphical “runInstaller” being the gate way we have to cross to achieve installation.  Of course there is the silent install, but to do that requires knowing all the secret handshake responses to make the silent installer work. Often the easiest way to get a response file is to capture the responses form a graphical run of the runInstaller.

There is another way, and that is using vncserver to run the graphic desktop on another machine. For example I can display the the graphical desktop on my Mac.

Here is the setup:

On the Linux box:

Distributed Transactions and EM12c Page Performance

While presenting at HotSos in Dallas, Tx, an attendee, (thank you Wenju! :)) asked how page performance issues could be identified when the call was being made remotely and not from the Oracle Management  Repository, (OMR) using the Page Performance console within Cloud Control.

Adding An EMC XtremIO Volume As An ASM Disk With Oracle Database 12c On Linux – It Does Not Get Any Easier Than This.

When Something Is Simple It Must Be Simple To Prove

Provisioning high-performance storage has always been a chore. Care and concern over spindle count, RAID type, RAID attributes, number of controller arms involved and a long list of other complexities have burdened storage administrators. Some of these troubles were mitigated by the advent of Automatic Storage Management–but not entirely.

Wouldn’t it be nice if the complexity of storage provisioning could be boiled down to but a single factor? Wouldn’t it be nice if that single factor was, simply, capacity? With EMC XtremIO the only factor storage administrators need to bear in mind when provisioning storage is, indeed, capacity.

Undocumented Application Engine Parameter: EnableAEMonitoring

This is part of a series of articles about new features and differences in PeopleTools 8.54 that will be of interest to the Oracle DBA.

Oracle Support Document 1640355.1: E-AE: Performance Degradation When Using Do Loop Action to Process Large Amount of Data on PT 8.52 & PT 8.53 describes a performance problem in Application Engine when a small but frequently executed loop.  Application Engine calls DBMS_APPLICATION_INFO to set MODULE and ACTION on v$session each time it goes round the loop.

In Memory XML Performance (XVM)

I wouldn’t believe the bad XMLType performance statement given stated in Martin Preiss’ blog post,…

Database Provisioning in Minutes: Using Enterprise Manager 12c DBaaS Snap Clone and NetApp Storage

RMOUG 2015 Training Days Review

I’m at HotSos Symposium 2015 speaking this week, so thought I would blog about the results of the conference I’m the director of and that finished up just two weeks ago.  I’m not admitting to being overwhelmed by OEM questions here, as I’m rather enjoying it.  I love seeing folks so into Enterprise Manager and look forward to more!  Keep the ideas for more blog posts coming!
