Problem with small fonts and GUI interface in SQLDeveloper with windows 10 (on Mac Parallel VM) ?

 

If you use sqldeveloper on windows 10 on mac parallel VM maybe you have the next issue: a very small fonts and GUI interface (Actually it's so hard to read every word )

The solution for that issue is change the properties for sqldeveloper.exe file:

On the next window on the compatibility tab, you need to select the option button "Change high DPI Seetings"

Here you need to change option High DPI Scaling override to value : SYSTEM

And after the change you'll have your sqldeveloper with very normal font size and GUI :D

Cheers

SQL Developer performance TIPs (MacOS)

A while ago, i have experienced problems related to sqldeveloper performance (and especially on my MacOS), for that reason i'll share some tips about that:

1.- Change Look and Feel to "Mac OS X". That option will consume less memory and will perform better: 

On SQLDeveloper Menu -> Preferences -> Environment

2.- To improve even more, disable Completion Insight.

On SQLDeveloper Menu -> Preferences -> Code Editor -> Completion Insight

3.- Disable options and Features unused.

On SQLDeveloper Menu -> Tools -> Features

4.- To adjust SQLDeveloper Options like memory consumption on the configuration file. In my case the file is stored on:

/Users/USERNAME/.sqldeveloper/19.1.0/product.conf

On that file we could modify for instance the jvm max memory consumption, add the next parameter:

AddVMOption -Xmx300m

Add32VMOption -Xmx300m

Add64VMOption -Xmx300m

And at next sqldeveloper reboot, we can see is already up with the new parameter, for example:

felipes-MacBook-Pro:19.1.0 felipedonoso$ ps -fea | grep sqldeveloper | grep Xmx

For right now that's all my tips. In the future i'ill add more tips.
