Configuring memory settings

Mapper is pre-configured with a maximum memory allocation of 1GB. In most cases, 1GB should be sufficient. If you work with large mappings, you might encounter an OutOfMemory error. If this happens, increase the Mapper memory allocation.

  1. Create a shortcut link to this file:

    <MAPPER_Install_Folder>/eclipse.exe

  2. Specify the Target property of the link.

    Use this format:

    <MAPPER_Install_Folder>/eclipse.exe -vmargs -Xms<MIN>m -Xmx<MAX>m

    where:

    • MIN is the minimum amount of RAM in megabytes, for example 512.

    • MAX is the maximum amount of RAM in megabytes, for example 1000.

    Example Target format: IONMapper/eclipse.exe -vmargs -Xms512m -Xmx1000m
