Tips

  • The new generation CWMS-Vue tabs are memory intensive, so increasing the maximum allotted memory setting for the CAVI help the performance of its CWMS-Vue plugin.   For any PCs with installed memory of 32GB or greater, it's recommended to increase the maximum allotted memory to 6GB or 8GB:
    • Edit the cavi.config file in notepad
    • Change the -Xmx2048m argument to -Xmx6144m or -Xmx8192m
  • A tutorial to setup the CAVI-Personal.config is available here: Creating Personal CAVI Config File
  • In addition to increasing the CAVI's maximum allotted memory setting, turning off a few graphical settings could help too:
    • Edit the cavi.config file in notepad
    • Comment out the following arguments under the "Graphical Issues" section

      • #vmparam -Dsun.java2d.d3d=false

      • #vmparam -Dsun.java2d.nodraw=true

      • #vmparam -Dprism.order=sw

Known Issues

  • Groups “File name” tab had to be manually updated from using the IP address to using the connection name. 
  • Tabulating in MS Excel date formatting has issues for dates including May 1-9 (Discourse Post).
