After some first baby steps with Oracle VM I wanted to push this thing a little bit further. So my idea was to have more than a couple of VM's running simultaneously. The Oracle VM told me however that I had not enough memory to do this. So I was sitting in front of my dedicated laptop and told the screen that there should be 4 GB inside. The laptop however had one of his funny days and told me (using free and top) that really nothing more than 572 MB would be inside the machine. Hmm - when a machine tells me something I am the first to listen. So I shutdown everything, got my screwdriver, opened the memory compartment and had a look. Indeed 1 bank of 2GB. I didn't check the second bank as this is hidden underneath the keyboard. Closing the machine and powering it up, I prepared myself for another round of telling it that it should recognize a little bit more than 572 MB. I examined the dmesg and still it told me that there was only 572 MB inside. Now imagine, you have just see...
Some of the stuff I do for a living. This mainly concerns working with Oracle Databases and Application Servers. Lately I picked up AWS, Azure and OCI.
