Location of temporary report documents

Kloss

Hello BIRT community,

I have a simple question. I know that BIRT produces temporary report files. Where are they located? I use BIRT 2.6.2 and call it via the Report Engine API. I don't use the Viewer.

Kloss,

Which temporary files are you referring to? In the EngineConfig class you can set the tmp directory birt uses by calling config.setTempDir(..).

Thanks. I mean the temporary report document that is produced from the .rptdesign file. 
I will try setTempDir(). Thanks.

Hi again. The reason I wanted to know the location is to make some performance tests and clear the temporary files for each turn. 
I set the temp directory now and have made a method to delete all files within this directory, but there seem to be never files in it. Why that? Are there other locations too? 
 
In case it is just a silly mistake, this is my method: 
<pre class='_prettyXprint _lang-auto _linenums:0'>public static synchronized void cleanTempFiles() {
try {
log.info("cleanTempFiles called");
File[] tempDirFiles = new File(getTempDir()).listFiles();

for (File file : tempDirFiles) {
if (!file.delete()) {
log.warn("unable to delete tempDir file: " + file);
} else {
log.info("tempDir file successfully deleted: " + file);
}
}

} catch (PropertyNotAvailableException e) {
e.printStackTrace();
}

}</pre>

I believe the data engine will write to this location when it processes a very large dataset, but it should clean itself up.

But it doesn't clean itself up the way I want it to. 
I.e. I compare the performance results of report generation with a normalized tables with a prepared, denormalized table in the database. It doesn't show any effect except for the very first test, because the engine keeps the temporary files. Any idea what I can do?

I am not exactly sure what the issue is. You could open a bugzilla request to get some more feedback from the dev team.
