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

问题描述

我遇到了一个很麻烦的问题，在ASP.NET应用程序中同时查看同一个报表多次同时我有这个异常：

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

系统配置的最大报表处理作业限制
管理员已达到

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

等我知道有吨

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.

私有子CrystalReportViewer1_Unload（ByVal sender As Object，ByVal e As System.EventArgs）处理CrystalReportViewer1。卸载
reportFile.Close（）
reportFile.Dispose（）
GC.Collect（）
End Sub

我在 HKEY_LOCAL_MACHINE\SOFTWARE\SAP中编辑PrintJobLimit注册表.NET Framework 4.0的应用程序BusinessObjects \ Crystal报表\Report应用程序服务器\InprocServer 和 HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects \ Crystal报表.NET Framework 4.0 \Report应用程序服务器\Server 为-1甚至到9999，仍然抛出异常。

I edit the PrintJobLimit registry in HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\InprocServer and HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\Server to -1 even to 9999, and still throw the exception.

以下是我调用我的报告的代码片段：

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

我建议在卸载过程之外移动您的关闭/ dispose / gc.collect代码。换句话说：

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

1. 载入报告


2. 指派给查看者控制


3. 在查看者控制中显示报告


4. 关闭查看者控制和卸载（完全）


5. 然后关闭/处理/ gc.collect查看者控件代码

1. Load report
2. Assign to Viewer Control
3. Show Report in Viewer Control
4. Close Viewer Control and Unload (completely)
5. Then close/dispose/gc.collect outside of any viewer control code

我的猜测是当报表正在清理时，查看器控件未完全关闭。

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

Crystal是一个内存密集型过程，非常简单。

Crystal is a very memory intensive process and very finicky.
