Most of the LC (local correction patch) could be applied by pkgadd  
  command if the patch ends with extension *pkg.

  Please read the corresponding patch direction (*.E file) carefully
  and decide if you want to apply them or not.

  Site restricted patches can not be applied, and patch for the
  product which are not installed in the system can not be applied
  as well.

  "lccheck" shell script is available under /pub/sxu/kclc_tools. This
  shell script will check whether your file transfer was complete one
  or not. Please change directory to where you placed patch & patch
  directions, and execute:
 
    lccheck PATCHID  (e.g. lccheck LC720103)

  to confirm if the sum of the files are correct or not.
