Crystal Reports 异常:已达到系统管理员配置的最大报表处理作业限制 [英] Crystal Reports Exception: The maximum report processing jobs limit configured by your system administrator has been reached

问题描述

我遇到了一个非常错误的问题，在 ASP.NET 应用程序中同时多次查看相同的报告后我得到了这个异常:

I'm facing a very buggy issue, in ASP.NET application after viewing the same report many times simultaneously I got this exception:

您的系统配置的最大报表处理作业限制已联系管理员.

The maximum report processing jobs limit configured by your system administrator has been reached.

等等，我知道那里有大量的解决方案，但它们都不适用于我.

Wait I know there are tons of solutions out there but all of them are not working with me.

1. 我把 ReportDocument.Close();ReportDocument.Dispose();在 CrystalReportViewer_Unload 事件中，仍然抛出异常.

1. I put ReportDocument.Close(); ReportDocument.Dispose(); in CrystalReportViewer_Unload event, and still throw the exception.

Private Sub CrystalReportViewer1_Unload(ByVal sender As Object, ByVal e As System.EventArgs) 处理 CrystalReportViewer1.Unload报告文件.关闭()报告文件.Dispose()GC.Collect()结束子

我在 HKEY_LOCAL_MACHINESOFTWARESAP BusinessObjectsCrystal Reports for .NET Framework 4.0Report Application ServerInprocServer 和 HKEY_LOCAL_MACHINESOFTWARESAP BusinessObjects 中编辑 PrintJobLimit 注册表Crystal Reports for .NET Framework 4.0Report Application ServerServer 到 -1 甚至到 9999，仍然抛出异常.

I edit the PrintJobLimit registry in HKEY_LOCAL_MACHINESOFTWARESAP BusinessObjectsCrystal Reports for .NET Framework 4.0Report Application ServerInprocServer and HKEY_LOCAL_MACHINESOFTWARESAP BusinessObjectsCrystal Reports for .NET Framework 4.0Report Application ServerServer to -1 even to 9999, and still throw the exception.

这是我调用报告的代码片段:

Here is the code snippet where I call my report:

 Table_Infos = New TableLogOnInfos()
                Table_Info = New TableLogOnInfo()
                Con_Info = New ConnectionInfo()

                With Con_Info
                    .ServerName = ConfigurationManager.AppSettings("server_name")
                    .DatabaseName = ConfigurationManager.AppSettings("DB")
                    .UserID = user_name
                    .Password = pass_word
                    .Type = ConnectionInfoType.SQL
                    .IntegratedSecurity = False
                End With

                Table_Info.ConnectionInfo = Con_Info

                If Session("recpt_lang") = "Arabic" Then
                    reportFile.Load(Server.MapPath("/Reports/") & "collectrecpt_new_ar.rpt")
                ElseIf Session("recpt_lang") = "English" Then
                    reportFile.Load(Server.MapPath("/Reports/") & "collectrecpt_new.rpt")
                End If

                For Each mytable In reportFile.Database.Tables

                    mytable.ApplyLogOnInfo(Table_Info)

                Next

                CrystalReportViewer1.ReportSource = reportFile
                CrystalReportViewer1.SelectionFormula = Session("SelectionForumla")
                CrystalReportViewer1 = Nothing

推荐答案

我建议将您的 close/dispose/gc.collect 代码移到该卸载过程之外.换句话说:

I would recommend moving your close/dispose/gc.collect code outside of that unload process. In other words:

1. 加载报告
2. 分配给查看器控件
3. 在查看器控件中显示报告
4. 关闭查看器控件并卸载(完全)
5. 然后在任何查看器控制代码之外关闭/dispose/gc.collect

我的猜测是在清理报表时查看器控件没有完全关闭.

My guess is the viewer control is not completely closed when the report is being cleaned up.

Crystal 是一个非常占用内存且非常挑剔的过程.

Crystal is a very memory intensive process and very finicky.
