Report Explorer Performance

edited January 2003 in End User
I'm encountering some real performance issues with the ReportExplorer.

Using the "\Demos\3. EndUser\1. Report Explorer" example:
time to start EXE: 80+ seconds
time to load 17K report in designer: 150+ seconds

This is over a cable connection from my home computer to the Oracle
database at work. What concerns me is that one of our customer's branch
offices is connected to the main office via a 56K line.

Is there something that I can do to resolve this?

Thanks in advance,

Ed Vander Hoek

    i'm facing exactly the same problem as my database grows. The problem is
    that report explorer fetchs all the blobs fields and it is very time
    consuming.

    A solution would be to fetch only needed blob as the user try to open a
    report.

    sorry for my english...

    Yes, that would be the best solution.

    Some work arounds:

    1. We can store the reports in the database, but cache the reports
    locally. At start up the application would check for updated reports,
    download them to the hard drive, and use Report Explorer with the local
    files.

    2. We can modify or rewrite the Report Explorer functionality ourselves.

    Would anybody from Digital Metaphors care to comment?

    Another alternative exists. If you use ASTA with the RB end user solution,
    you can configure the SQL options set property on the ASTA CDS to
    conditionally fetch BLOBs and memos and toggle it at runtime to get this
    behavior.

    We would probably have to rewrite the report explorer component to take into
    account that the template fields are loaded on demand. You can try to fire
    the query for the rbItems to retrieve the templates on demand using a custom
    report explorer form and using events/methods available to it. We've
    researched this before, but have not been successful at creating a solution
    at this time.

    Thanks for the response, Jim. I'll look into modifying the Report
    Explorer next week. I'll let you know if I find any reasonable way of
    doing it.
