I recently installed SQL Developer on my machine and when I click on the exe file I received the below error.
Cause: As from the message the error is related to virtual memory allocation.
Go to the path where SQL Developer is installed, <SQLDEVELOPER>/jdev/bin/ide.conf
Search for ‘AddVMOption –Xmx’
The memory allocated could be higher, in my case it was AddVMOption –Xmx640M, Changing it to ‘AddVMOption -Xmx256M’ worked fine.
