You can override settings provided in the GroupWise Administration Console by using startup switches in the GWIA startup file (gwia.cfg). The default location for the gwia.cfg file is in the wpgate/gwia subfolder in the domain folder.
When you create a domain and install the GWIA, an initial gwia.cfg file is created. This initial file includes the --home startup switch set to the wpgate/gwia subfolder.
Startup switches specified on the command line override those in the gwia.cfg file. Startup switches in the gwia.cfg file override corresponding settings in the GroupWise Administration Console. You can view the gwia.cfg file from the Configuration page of the GWIA console.
