Weblogic Portal 10.3.6 generic installer on Mac OS X – Insufficient Disk Space error

Trying to use the portal103_generic.jar installer on Mac OS X 10.11.1 gives this error even though you have plenty of free space:

A quick Google turns up this question and answer. Quick fix, run passing this option: -Dos.name=unix, so:

java -Dos.name=unix -jar portal103_generic.jar

Although others reported this avoided the issue, I then got this issue instead:

Exception in thread "chmodFile" java.lang.Error: Unix is not a supported OS platform.
 at java.lang.UNIXProcess$Platform.get(UNIXProcess.java:164)

Following additional suggestion here, using -Dspace.detection=false instead avoided the issue.

Reminder to self: MySql on Mac OS X is installed to /usr/local/mysql[version]

Apparently it’s been a while since I started up mysqld on my Mac for development (as I’ve been using MongoDB for a lot of my local dev). Anyway, apparently also I had already written a short article over a year ago to remind myself that the default location for the Mac install of MySQL is to /usr/local/.

Reminder to self again: remember to search your previous posts to remind yourself where MySQL is installed.

Adding transparency to existing images using Gimp

To modify an existing image so it has transparency in Gimp, here’s a quick summary of steps from this section of the Gimp docs:

  • Open the image
  • Add an alpha layer: Layer > Add Transparency > Add Alpha Layer
  • Show the Channels dialog: Windows > Dockable Dialogs > Channels – you now see one of the original image and the Alpha layer
  • Select the original layer, then use the Eraser tool to erase the original background from the image (the part that you want to be transparent).
