Question: Jasper caching #148

Open jasminkaldzija opened 8 years ago

jasminkaldzija commented 8 years ago

Hi everyone,

How can I delete report execution from execution list? I want to remove that from session after exporting it (it uses a lot of memory)?

Sincerely, Jasmin

yaroslav-kovalchyk commented 8 years ago

Hi Jasmin, very good question. Currently JasperReportsServer doesn't provide this functionality, but it's definitely needed. I'll create enhancement request for that.

jasminkaldzija commented 8 years ago

Nice. Will session executions be deleted from JasperReport Server after calling "session.logout()"?

yaroslav-kovalchyk commented 8 years ago

yes. Currently logout is the only way to clear reportExecutions from memory.

jasminkaldzija commented 8 years ago

Thank you. "session.logout()" will be good enough for now, but I'm still waiting for new functionality :yum:

yaroslav-kovalchyk commented 8 years ago

If you need some more functionality, than just removing of reportExecutions from memory, then fill free to file more issues here. Thank you for this valuable feedback.

jasminkaldzija commented 8 years ago

Thank you.

Actually there is one more thing. Is there any way to find out "totalPages" before reportExecution turn to "ready" status. When status turns to "execution" it starts filling "report" and it increases "currentPage" but "totalPages" is null. Or, is there any way to make estimation time for reportExecution (not necessary in time format, it can be in percentages) ?

Sincerely, Jasmin

yaroslav-kovalchyk commented 8 years ago

Hi Jasmin, I see your issue, but unfortunately there is no way to know totalPages before execution is ready.

jasminkaldzija commented 8 years ago

Hi Yaroslav,

I want to report something. I'm not sure what exactly is problem. When I generate report which returns pdf file with 20 000 pages it works fine. But problem is with report with 70 000 pages. Whey execution turns from "execution" to ready, export status should be changed from "queue" to "execution". In by case it turns to "cancelled".("Report generation cancelled" in server log).

Version of server is 5.6.0

Sincerely, Jasmin

yaroslav-kovalchyk commented 8 years ago

It's technical cancel, that happens on report execution complete. It shouldn't be visible outside, but unfortunately it is visible and confusing users. We will fix it. For now just ignore this status and load your output resource, cancelled export will be restarted automatically.

jasminkaldzija commented 8 years ago

Hi Yaroslav,

In my case sometimes export get status "cancelled" before execution is finished. Than I run it again(create new export request) and it works fine. But if I run 2+ executions, export status become "failed" with exception:

(Unexpected error) java.lang.NullPointerException at com.jaspersoft.jasperserver.remote.services.impl.RunReportServiceImpl.executeExport(RunReportServiceImpl.java:380) at com.jaspersoft.jasperserver.remote.services.impl.RunReportServiceImpl$2.run(RunReportServiceImpl.java:343) at com.jaspersoft.jasperserver.api.logging.util.LoggableExecutorService$1.run(LoggableExecutorService.java:59) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)

yaroslav-kovalchyk commented 8 years ago

Hi Jasmin, what server version are you using?

yaroslav-kovalchyk commented 8 years ago

Closed by mistake

jasminkaldzija commented 8 years ago

I use 5.6.0 version.

This is how I launch report: ... ... executionRequest .setAsync(true) .setOutputFormat("PDF");

executionRequest.setReportUnitUri(path + "/"+reportId); ... ... ... OperationResult result = session.reportingService(). newReportExecutionRequest(executionRequest)

yaroslav-kovalchyk commented 8 years ago

Rather old version... It's definitely server side issue and I suppose this issue is already fixed in latest version. Please upgrade if possible. Otherwise you can contact our technical support.

jasminkaldzija commented 8 years ago

Thank you Yaroslav, I will try one of the newer version.

Hi everyone, Here is the issue I am facing: One user has access to report 1 in which ABCD data is available and E is missing and once she clicks on home log out log back in and refresh and open the report again then she can see ABCDE in the report. at the same time I have opened the same report and I was able to see ABCDE. What could be the reason she was not able to see ABCDE in the first place is it some thing to do with Browser Cache. Please advise.

Thanks, Rajeev
