IR51889: The Resource Manager and eClient to not support byte serving of PDF files which causes performance problems with large PDF's.

APAR status

• Closed as program error.

Error description

• The crux of the problem is that we don't support byteserving of
  PDF docs, which is sort of like streaming, to give you a flavor
  for what it means. Large PDF documents can take over a minute to
  load in the PDF Viewer without this support, while the first
  page comes up in less than 10 seconds (most times less than 5)
  with support for Byte Serving.
  
  There are two pieces of work required to address this issue:
  
  1. Support direct retrieve in the eClient. (This isn't required
  for Accenture/C-IV or any other customer that has a custom app
  and uses diect retrieve already)
  2. Support byteserving in the Resource Manager
  

Local fix

• N/A
  

Problem summary

• PDF Viewer is downloading entire file before
  presenting first page to user.
  

Problem conclusion

• The resource manager has been enhanced to
  support byte range support in the manner
  that the
  PDF Viewer expects. This allows the PDF
  viewer to access the table of contents and
  other
  information required to present the first
  page quickly, subsequent page viewing
  performance is
  also enhanced.
  

Temporary fix
