Trace Collier has been updated again. Mostly bug fixes, but there’s a little enhancement too. The current release is 0.21.
Trace Collier has been updated after a couple of foibles were found during the processing of a trace file. Continue reading Trace Collier Utility – Updated
I have a table with dates in, and some NULLs. Two people, on the same database, running the same
SELECT query, in the same schema, with the same privileges, get vastly differing results. Why? Fine Grained Auditing is not at play here. Continue reading Interesting Foible with Oracle Dates
I recently posted a useful
oraenv for Windows utility. This has been updated so that you can run it in batch files by passing the desired Oracle SID on the command line. Details at http://qdosmsq.dunbar-it.co.uk/blog/2016/08/oraenv-for-windows/
Regular maintenance is important for your home’s windows. It can help them last longer, perform better and look great. Well-maintained windows will also serve to enhance the security and appearance of your home, guarding against the effects of temperature fluctuations, weather and debris. Follow these maintenance tips from Rescom’s expert window technicians to help keep your windows in shape. Visit reliablewindowandsiding.net for more information about professional maintenance.
Wipe down windows regularly with a damp cloth to remove dust and dirt. Don’t use too much water, especially on wood frame windows, as moisture can lead to rot. For vinyl windows, used a combination of warm water, a mild detergent and a soft scrubbing brush.
Use a glass cleaner in between deep cleans to keep the windows sparkling. Don’t neglect the window casing and adjacent wall area, in an effort to remove that build-up of dirt and debris in hard-to-reach components. Window jams can occur when dirt is allowed to accumulate in those areas.
In spring and fall, perform a thorough inspection of your windows, being sure to check the condition of the window frame and sash. Keep an eye out for signs of rot, especially on wood frames, that can indicate moisture infiltration.
Be on the lookout for moisture in double- or triple-paned windows, which could mean the seal has failed and must be replaced. Allowing a failed seal to remain will reduce the insulation capacity of your windows.
Have the sun’s harsh UV rays caused areas of the frame to become brittle and warp? Is paint peeling in certain areas? Is the weather stripping still intact? Replace, repair and repaint as needed. Caulk any gaps between the wall and window casing.
Gaps around your window allow for energy leakage, increasing your bills and reducing the efficiency of your home. For optimal sealing, replace all worn rubber seals to keep air and water leaks at bay and further secure the window in place. You can also use spray insulation or caulking to do the job.
Repair any cracks, holes, and splinters in the window to avoid further deterioration. If you notice cracked or broken glass, get it repaired or replaced immediately to prevent energy leakage and accidental cuts. This task is best left up to professionals.
Check the Fit
Frames and sashes can change subtly in size over time, thanks to usage and exposure to temperature cycles. As a result, gaps can form between window components, allowing air and water infiltration. Carefully check the fit of all window components. Make sure they can open all the way and that they close and lock completely. Swelling or warping of the window frame or sash means moisture is present.
It’s always nice to know which extra cost Oracle options are enabled, whether deliberately or silently as the result of some patching that has taken place.

I found a broken check constraint, one that simply wouldn’t work, on a database. It was created as:
... CHECK(COLUMN_NAME IN ('Y','N',NULL)) ;
Try it yourself, it doesn’t work! Anyway, I needed to find if there were any other check constraints broken in this manner, so I did the following:
This applies to Linux, Unix as well as Windows, but affected me on a Windows 2012 Server running Oracle 126.96.36.199 Enterprise Edition.
My user on the server was an administration user, but not in the
ora_dba group. This is required to
connect / as sysdba within SQL*Plus. The SYS password had been changed recently but whoever did it, did not update the password vault. The users were urgently requiring their database be started, I was the only DBA in the office, the SYS password was unknown, and my user didn’t belong directly to the
ora_dba group. What to do? Continue reading How to Start an Oracle Database When You Are Not in the DBA Group
For no reason, after many weeks of use, RMAN suddenly cannot connect:

I’ve recently begun a new contract migrating a Solaris 9i database to Oracle 11gR2 on Windows, in the Azure cloud. I hate windows with a vengeance and this hasn’t made me change my opinion!
One of the planned improvements is to have everyone using a standard, central
tnsnames.ora file for alias resolution. A good plan, and the company has incorporated my own tnsnames checker utility to ensure that any edits are valid and don’t break anything.
I found that the
tnsnames.ora in my local Oracle Client install, was not working. Here’s what I had to do to fix it. Continue reading Tnsnames.ora, IFILE and Network Drives on Windows
As a contractor I often have to fill in and sign various contract agreements. These are usually tens of pages in length, and while I only have to sign one page, I still must scan in and send back each and every page, even the untouched ones. It would help if a PDF with form filling abilities was supplied, but hey, that’s only rarely the case. This is how I do it. (On Linux – Windows users mileage may vary!) Continue reading Printing, Completing & Scanning PDF Documents
If you find that your Raspberry Pi 3 (or any above), those with built in WiFi and Bluetooth, loses the WiFi connection after a period of inactivity, then this thread on the Raspberry Pi Forums, which will open in a new tab, might be of interest. Have a read. If you want to miss out on the preliminaries of the thread, start reading here instead.
The problem is likely to be the power saving mode of the Wifi. To check the current setting:
sudo iw dev wlan0 get power_save
If you are/will be affected, it will reply with:
If so, all you need to do is:
sudo iw dev wlan0 set power_save off
I’m not affected yet, but I’m making a note here, just in case!
Have you ever needed to trawl through an Oracle Trace file to extract the SQL statements executed and found a whole load of bind variables have been used, so you need to find the
BINDS section, extract the values, and virtually paste them into the parsed SQL statement?
No? This utility isn’t for you then. Continue reading Trace Collier – An Oracle Utility to Mine 10046 Trace Files
I hate it when I click on a task bar icon to open up a snoozing application, and a couple of seconds later, there’s a preview of the application showing at the bottom of the screen. I don’t need it as the icon tells me what it is, thanks! Getting rid is easy: Continue reading Turn Off Task Bar Thumbnail Previews on Linux Mint Cinnamon 17.3 through 20.1
With a title like that, I should get some hits! 😉
