HP Mini T210 3F0 boot failure and System Rollback Data disk space issues with Roxio BackOnTrack / aswrvt.sys
If you have an HP Mini 210 or 100 and have had issues with disk running out of space, failures to boot, I feel for you. After a heap of hassle, I sorted my out problems without having to reinstall Windows, and so I'm sharing my experiences as I found many many people with the same issue, but no central resolution. The issues I've had are as follows

Not really an excuse but when it is your conference, you don't have time in the run up to 'polish your slides', so my top tip, Never agree to a new presentation at you own event, stick to one you are happy with so you can simply switch on the projector and go.
Great advice, wish I had listened to it.
Thursday in Ireland I had two presentations, the first was a great slide (more...)
Since some time I have been adding
WHERE 1=1 to all my queries.
I get queries like this:
SELECT * FROM emp e WHERE 1=1 AND e.ename LIKE 'A%' AND e.deptno = 20
Lots of people ask me what’s the use of this
You know I like to type as little as possible but here I am typing a lot of extra characters. And yet, it makes my development life a (more...)
I recently came across the book called “Oracle Database Transactions and Locking Revealed” by Tom Kyte and Darl Kuhn. Usually, any new book by Tom Kyte is a big deal and acquires a huge following very quickly. Strangely enough there was only a single review on the Amazon, before I added my own.
For the reasons unknown to me, this book is literally ignored. I haven’t seen posts on the oracle-l about it, on the (more...)

If you are using Red Hat derivative, like me, it’s a simple RPM package. Check the content of the package, like this:

After saying a quick goodbye to everyone, I got in a taxi and headed for the airport. I was a little on the early side, but as I’ve said before, it’s better to be early than late where airports are concerned. I wanted do have a Guinness in the bar in the airport, like I did with Patrick Hurley last year, but the queue was too long, so I settled for an authentic Irish diet (more...)
Having got to OUG Ireland, here’s what happened…
The first session I got to see was Nikolay Kovachev from TechnoLogica speaking about “12c PDBs, Snapshots & Change Management”. Bulgaria in da house! The session started with an intro to ZFS (snapshots, copy-on-write (COW), clones), then a quick intro to the Oracle multitenant architecture. From there it was on to PDB snapshot cloning using ZFS. Because of the ZFS COW functionality, this is really quick. (more...)
The day started early, about 1 hour before my alarm in fact. I got up, lay in the bath for a while drinking a can of Monster and considering the day ahead, got out of the bath, puked, then got my shit together ready for the taxi. I’ve been ill this week. That combined with sleep deprivation, nerves and the Monster kinda turned my stomach.
The taxi ride to the airport was really good. The (more...)
We currently are working on a bug with Oracle Support with dbms_stats in 220.127.116.11.
That may be the subject of a latter post, but in a nutshell, here’s the issue
SQL> exec dbms_stats.gather_table_stats('MY_SCHEMA', 'MY_SCHEMA'); BEGIN dbms_stats.gather_table_stats('MY_SCHEMA', 'MY_SCHEMA'); END; * ERROR at line 1: ORA-21700: object does not exist or is marked for delete
Now obviously that’s not meant to be happening, and it pertains to incremental stats on a database (more...)

I also created a new appliction with grails 2.4.4. From this application I took the BuildConfig.groovy and copied the content into to the BuildConfig.groovy of the application I wanted to update. Then I added the changes to the BuildConfig which are necessary for the application.
In the datasource of the application I (more...)
To enable tunneling for use with Discoverer Plus, use this workflow:
