Launch settings (M)

It is possible to personlizepersonalise the launch settings of Ancestris.

In general, you should not need to set or modfymodify them.

However, in some specific circumstances, you may want to tweektweak them them a bit.

It is as simple as editing the line in the Ancestris'Ancestris configuration file. Please refer to the location of the configuration file page to know where it is located.

Set memory size for large genealogies

Ancestris works perfectly fine with genealogies of several dozens ofor thousands of individuals.

You can get Ancestris to work with several genealogies at the same time..

We recommend a 4 GbGB memory for very large genealogies.

Ancestris can open and manage a simple genealogy of 600 600,000 individuals.


For very large genealogies, we recommend that you change Ancestris's startup parameters to increase maximum memory size for Java.

  • Parameter to change:  -J-Xmx to 8Gb8GB for instance.
default_options="-J-Xmx8g --laf Nimbus --branding ancestris --locale fr -J-Xms96m"

We also recommend, if needed, to reboot your device and to only start Ancestris and nothing else, so that all memory available will be allocated to Ancestris.

 

Set default language

The default language can be set in Ancestris preferences.

It can also be initialised to a language of your choice using the launch setting.

  • Parameter to change:  --locale to the 2-digit-language code. ExempleExample : "en".
default_options="-J-Xmx1g --laf Nimbus --branding ancestris --locale en -J-Xms96m"

 

Set default look and feel

The default look and feel can be set in Ancestris preferences.

It can also be initialised to a look and feel of your choice using the launch setting.

  • Parameter to change: change --laf to the look-and-feel name provided in Ancestris preferences.
default_options="-J-Xmx1g --laf Nimbus --branding ancestris --locale en -J-Xms96m"

For the standard look and feel, remove the parameter from the line.

In very rare circumstances, if you modify the default size of the fonts and icons on your computer or use a very large screen, Ancestris might displydisplay iconits sizeicons in too small proportions.a size.
