The Denodo Control Center allows the user to configure the Java Virtual Machine Memory parameters for each of the Denodo Platform’s services.
To modify any memory parameter in a system with a Desktop environment:
If the Denodo Platform is installed on an environment without a windows system, the memory configuration can be modified by editing the configuration files of the different servers and tools.
For example, for the Virtual Data Port Server, the file:
contains the following property that can be modified as needed:
Once the configuration file has been updated, the script
must be executed in order to propagate the changes in the startup scripts. After the execution of this script, the next time a server or a tool is started, it will use the new JVM startup options.
Keep in mind that, although the modifications in the startup options are finally applied to the startup scripts (for example, vqlserver.bat or vqlserver.sh), these files should never be modified directly. Installing a new update can modify these files automatically and therefore the startup options could be overwritten.
Also note that the JVM settings of the Denodo Solution Manager can be modified following the same steps in the Solution Manager.
