ExportToStream - MULTI USER ENVIRONMENT - ABOUT 20 concurrent users

50 Views

Hi:

Does Report.ExportToStream(ExportFormatType.PortableDocFormat)

cause problems in a MULTI USER / CONCURRENT USERS environment?

2 Namespaces being used are :

using CrystalDecisions.CrystalReports.Engine;

using CrystalDecisions.Shared;

Example:

-There is a report called “Performance.RPT” in a “Reports” folder under the website named “PKSSSystem”.

- In production, 20 concurrent users are accessing the same report ““Performance.RPT” , and the report is exported to Stream

with Report.ExportToStream(ExportFormatType.PortableDocFormat), resultant byte[] array is stored in the database and pulled back as an pdf file on a button click “SavePDF”, “GeneratePDf” etc…

are there any concurrency issues expected as given in the support forums below.

3. Also what are 1CPL and 3 CPL. Do we need to have a concern with CPL stuff while using ExportToStream in the code??

4) Environment: Ms Visual studio 2008, CR reports Engine Version 12.x.CR Engines are available on webserver and directly accessed from the aspx - c# page.

Your quick response is greatly helpful - Thanks
