PI88948: EXPAND OF A JES FILTER CAN TAKE FEW MINUTES IN EXPLORER FOR Z/OS ON VDI ENVIRONMENT.

APAR status

• Closed as program error.

Error description

• When IBM Explorer for z/OS Version 3.0.1.6 or
  Rational Developer for System z - RDz - v9.5.1.4, are installed
  on a remote network drive as part of a Virtual Desktop
  Infrastructure (VDI), then expanding a JES filter can take few
  minutes.
  
  Steps to reproduce:
  
  - Map a network drive to an RDz/IDz installation
  - Start RDz/IDz
  - Connect to z/OS
  - Expand filter My Jobs and observe the workbench being
  unresponsive for 30 seconds or more.
  

Local fix

• Problem does not happen with a new workspace or after having
  cleared the cache in menu
  Window > Preferences > Remote Systems > File Cache
  and click on Clear Cached Files
  

Problem summary

• When using a work space that is located on a network drive,
  expanding JES filters can be time consuming.
  

Problem conclusion

• To read the JES filter results, a file is downloaded from the
  host to the RemoteSystemTempFiles project (where all remote
  downloads go) of the user workspace. To ensure the downloaded
  file is in sync with the workspace, a call is made to sync up
  everything in the RemoteSystemTempFiles. Where there are a lot
  of downloaded files and a user does this over a network, that
  call is very expansive but also unnecessary since all that is
  needed to sync up is to refresh the parent folder of the
  downloaded JES filter results file.
