Zen reports - Error rendering Excel output

#ZEN #Caché

Hi,

We maintain a few Zen reports that output in Excel format.

Recently we started to observe that some reports fail and return the following error.

CSP error occurred
Error: Error rendering: OS code =1Use $log=1 to check
ErrorNo: 5001

I have extracted the exception details from the log file

Has anyone seen this exception rendering Zen Reports?

JVM is probably out of memory. Try this.

1. Define Excel server at SMP > System > Configuration > Zen Report Excel Servers > Zen Report Excel Server, let's say at port 44444

2. Start it. Copy OS command. Should be something like:

C:\InterSystems\Ensemble\lib\ExcelExporter\runserver.bat -port 44444 -numthreads 5 -loglevel 3 -maxlogfilesize 32000 -logrotationcount 100 -numpingthreads 5 -pingport 44445 2>&1

3. Stop Excel server

4. Execute the command from 2 in OS terminal, but set JVM heap size. See how.

5. In your ZEN report add:

Parameter EXCELSERVER = 44444;

to use your excel server.

6. Recompile report and try to run it again.
