Chart too big and temporary files

[sdemelis]

Hello,

I have a problem with a chart that seems too big for my server. I increased the size of the chart putting the Height property=700.

When I executed the report, the server started to create temporary files and it stopped only when it  reached the maximum number of files in the folder (returning the error " Disk quota exceeded"). I decresead the Height to 650 and the report works fine.

Do you have any suggestion to fix the problem?

 

thanks

A change of chart height will change your number of files in a directory, isn't it ?

Although I  do not understand your question, an error  of  "Disk quota exceeded" should be  related to your OS setting.

Hello,

thanks for your answer, but my problem is not the disk quota error. I could increase the quota but at the next execution I will reach the new limit.

The report generates more than 100000 temporary files for each execution: my problem is the number of temporary files generated. I don't understand why changing the chart height from 650 to 700 causes this problem.

It does not make sense. I check my temporary files of JFreeChart in Jasperserver under Tomcat ($TOMCAT_HOME/temp). Its pattern is prefix +~JF and suffix .tmp

One chart generates one temporary file, no more no less.

 

Does your temporary files like this pattern ? If not, you should change another direction to inspect. Perhaps a varible name "height" inside your report or scriptlet to multiple number of temporary files.

If the chart height is less than 700, I have the same temporary files as you. If it's 700 or more, the server creates a different type of temporary files, something like virt9195358_210345_23410_1291982944.

Your issue is interesting. Your JasperServer turns on virtualizer as your chart height reaches 700.

It is hard to trace your issue without more detail information (such as your JRXML, scriptlet, version of JasperServer).

I am just an amateur and cannot spend too much time here. I wish some gurus read this message and help you.

Sorry and good luck.

Hi icecreaming,

thanks for your time :)

If someone else has some clue about this problem, here some more info: the server version is 4.0 and the chart is in a subreport that contains only this chart, nothing else. Its datasource is a subdataset of a javabean that is the datasource for the main report. Also the main report contains 16 subreports (yes, it's full of data...), but the total number of pages for the entire report is about 7 or 8.
