Version 24.3.1 Java Memory -Xms -Xmx Flags

J-Mar 7 2025

Windows 10, SQL Developer 24.3.1

I added the following lines to product.conf file in c:\users\username\appdata\roaming\sqldeveloper\24.3.1

-AddVMOption -Xms1G

-AddVMOption -Xmx4G

However, when I start sqldeveloper.exe (which runs the 64 bit version), in help→about→properties I see the same value for
java.memory.heap.init 134217728
java.memory.heap.max 2147483648
no matter what I change the xms and xmx settings to.

I tried not including the xms flag, tried changing the units to bytes, kilobytes, and megabytes, and tried using the 64 bit specific flags.

I confirmed that help→about→properties for user.conf is pointing to the product.conf file I edited.

I don't think it's a reporting issue, either. When I work on a large model within the Data Modeler extension, I run out of memory at 2G.
