Oracle 9i有多个系统服务必须都启动之后才能正常工作,但逐个启动比较费事,多数学习Oracle但机器又不是太好的朋友也不能容忍每次都自动启动Oracle服务(那样512MB的内存在启动时就所剩无几了),所以通常都是要用了再启动,这里给出了批量启动windows系统服务的一个例子,介绍了操控windows系统服务的技巧:

首先新建一个Windows Application工程,取名为Oracle Starter

粘贴如下代码文件:

Form1.Designer.vb

Partial Public Class Form1

Inherits System.Windows.Forms.Form

<System.Diagnostics.DebuggerNonUserCode()> _

Public Sub New()

MyBase.New()

'This call is required by the Windows Form Designer.

InitializeComponent()

End Sub

'Form overrides dispose to clean up the component list.

<System.Diagnostics.DebuggerNonUserCode()> _

Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing AndAlso components IsNot Nothing Then

components.Dispose()

End If

MyBase.Dispose(disposing)

End Sub

'Required by the Windows Form Designer

Private components As System.ComponentModel.IContainer

'NOTE: The following procedure is required by the Windows Form Designer

'It can be modified using the Windows Form Designer.

'Do not modify it using the code editor.

<System.Diagnostics.DebuggerStepThrough()> _

Private Sub InitializeComponent()

Me.Label1 = New System.Windows.Forms.Label

Me.ListBox1 = New System.Windows.Forms.ListBox

Me.Button1 = New System.Windows.Forms.Button

Me.Button2 = New System.Windows.Forms.Button

Me.SuspendLayout()

'

'Label1

'

Me.Label1.AutoSize = True

Me.Label1.Font = New System.Drawing.Font("Tahoma", 12.0!, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, CType(0, Byte))

Me.Label1.Location = New System.Drawing.Point(13, 13)

Me.Label1.Name = "Label1"

Me.Label1.Size = New System.Drawing.Size(122, 22)

Me.Label1.TabIndex = 0

Me.Label1.Text = "Oracle Starter"

'

'ListBox1

'

Me.ListBox1.Font = New System.Drawing.Font("Tahoma", 12.0!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))

Me.ListBox1.FormattingEnabled = True

Me.ListBox1.ItemHeight = 19

Me.ListBox1.Location = New System.Drawing.Point(13, 75)

Me.ListBox1.Name = "ListBox1"

Me.ListBox1.Size = New System.Drawing.Size(436, 175)

Me.ListBox1.TabIndex = 1

'

'Button1

'

Me.Button1.Location = New System.Drawing.Point(322, 257)

Me.Button1.Name = "Button1"

Me.Button1.Size = New System.Drawing.Size(127, 34)

Me.Button1.TabIndex = 2

Me.Button1.Text = "Stop all services"

'

'Button2

'

Me.Button2.Location = New System.Drawing.Point(188, 258)

Me.Button2.Name = "Button2"

Me.Button2.Size = New System.Drawing.Size(127, 34)

Me.Button2.TabIndex = 3

Me.Button2.Text = "Start all servies"

'

'Form1

'

Me.AutoScaleBaseSize = New System.Drawing.Size(6, 14)

Me.ClientSize = New System.Drawing.Size(461, 304)

Me.Controls.Add(Me.Button2)

Me.Controls.Add(Me.Button1)

Me.Controls.Add(Me.ListBox1)

Me.Controls.Add(Me.Label1)

Me.Name = "Form1"

Me.Text = "Oracle Starter"

Me.ResumeLayout(False)

Me.PerformLayout()

End Sub

Friend WithEvents Label1 As System.Windows.Forms.Label

Friend WithEvents ListBox1 As System.Windows.Forms.ListBox

Friend WithEvents Button1 As System.Windows.Forms.Button

Friend WithEvents Button2 As System.Windows.Forms.Button

End Class

Form1.vb

Imports System.ServiceProcess

Imports System.Threading

Public Class Form1

'Private procName As String

Private procArray(5) As String

Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Activated

End Sub

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

procArray(0) = "OracleMTSRecoveryService"

procArray(1) = "OracleOraHome92Agent"

procArray(2) = "OracleOraHome92TNSListener"

procArray(3) = "OracleServiceSFSVDB"

procArray(4) = "OracleOraHome92HTTPServer"

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim backThread As Thread

Dim i As Int16

For i = 0 To 4

backThread = New Thread(AddressOf procClass.StopProc)

backThread.IsBackground = True

procClass.procName = procArray(i)

Label1.Text = "Stopping service: " + procClass.procName + " ..."

Me.Refresh()

backThread.Start()

backThread.Join()

ListBox1.Items.Add("Service: " + procClass.procName + " Stopped")

Me.Refresh()

backThread = Nothing

Next

Label1.Text = "All services stopped"

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim backThread As Thread

Dim i As Int16

For i = 0 To 4

backThread = New Thread(AddressOf procClass.StartProc)

procClass.procName = procArray(i)

Label1.Text = "Starting service: " + procClass.procName + " ..."

Me.Refresh()

backThread.Start()

backThread.Join()

ListBox1.Items.Add("Service: " + procClass.procName + " Started")

Me.Refresh()

backThread = Nothing

Next

Label1.Text = "All services started"

End Sub

Public Class procClass

Public Shared procName As String

Public Shared Sub StopProc()

Dim servController1 As ServiceController = New ServiceController(procName)

If servController1.Status = ServiceControllerStatus.Stopped Then

ElseIf servController1.Status = ServiceControllerStatus.Paused Then

servController1.Stop()

servController1.WaitForStatus(ServiceControllerStatus.Stopped)

ElseIf servController1.Status = ServiceControllerStatus.Running Then

servController1.Stop()

servController1.WaitForStatus(ServiceControllerStatus.Stopped)

End If

End Sub

Public Shared Sub StartProc()

Dim servController1 As ServiceController = New ServiceController(procName)

If servController1.Status = ServiceControllerStatus.Running Then

ElseIf servController1.Status = ServiceControllerStatus.Paused Then

servController1.Continue()

servController1.WaitForStatus(ServiceControllerStatus.Running)

ElseIf servController1.Status = ServiceControllerStatus.Stopped Then

servController1.Start()

servController1.WaitForStatus(ServiceControllerStatus.Running)

End If

End Sub

End Class

End Class

总结:

这个实例只是运用了系统服务控制的基本功能,高级功能还不甚了解,对于多线程的运用还不是很明确,望大家指正

改进:

程序在运行时如果焦点离开,用户界面便会锁死,虽然尝试了多线程,仍然不理想,应该还Join()方法有关,多次修正未果,请高手指点,谢谢!

测试平台:

Windows Server 2003,Visual VB.NET 2005 Beta 1
