Question

在Websphere服务器中部署EAR（大小：230 MB）文件时，我收到OutOfMemory错误。在增加堆大小之后，有时部署会成功。我已经分析了堆转储，发现了可疑的泄漏对象，但不知道以后如何进行。

function button ($title,$instance,$acct,$pass) {
    ###################Load Assembly for creating form & button######

    ##############Define text label3

    $textLabel3 = New-Object "System.Windows.Forms.Label"
    $textLabel3.Left = 25
    $textLabel3.Top = 85
    $textLabel3.Text = $pass

    ############Define text box1 for input
    $textBox1 = New-Object "System.Windows.Forms.TextBox"

    $button2.Width = 100
    $button2.Text = "Cancel"
    $button2.DialogResult = [System.Windows.Forms.DialogResult]::Cancel

    ############# This is when you have to close the form after getting values
    $eventHandler = [System.EventHandler]{
        $textBox1.Text
        $textBox2.Text
        $textBox3.Text
        $form.Close()
    }

    $button.Add_Click($eventHandler) 

    #############Add controls to all the above objects defined
    $form.Controls.Add($button)
    $form.Controls.Add($button2)

    $form.Controls.Add($textBox3)
    $ret = $form.ShowDialog()

    $result = $null
    #################return values
    if ($ret -eq 'OK') {
        # if NOT cancelled, return whatever is in the 3 text boxes
        $result = $textBox1.Text, $textBox2.Text, $textBox3.Text
    }

    # Dispose of the form
    $form.Dispose()

    return $result
}

$return= button "SSRS Configuration" "Instance Name" "Domain\ServiceID" "Password"

# test if the function returned anything, otherwise it was cancelled
if ($return) {
    #Below variables will get the values that had been entered by the user

    $return[0]
    $return[1]
    $return[2]

    # for better readability, create the arguments for the Setup.exe as array

    $arguments = '/q', 
                 '/IACCEPTSQLSERVERLICENSETERMS', 
                 '/ACTION="install"',

并在WAS日志中达到以下错误

背景中是否存在任何胭脂过程或阻塞？

Answer 1

您没有编写版本，拓扑（单个，网络部署），也没有编写应用程序的方式（控制台，wsadmin等等）。如您在日志中所看到的，在EJB部署调用期间发生OutOfMemoryError。您需要为ejb部署增加内存，您可以将其设置为文件或在操作系统级别。检查此帖子Getting OutofMemory condition while deploying a large application in WebSphere Application Server

1）在install-root / deploytool / itp / EJBDeploy.sh文件中进行设置

EJBDEPLOY_JVM_HEAP =“-Xms1024 -Xmx1024”   ejbdeploy.sh文件。

2）在操作系统环境中进行设置。

在OS环境中设置EJBDEPLOY_JVM_HEAP ='-Xms1024 -Xmx1024'   变量。

我还会在AdminAgent01配置文件中为您的管理服务器增加内存，因为您似乎正在使用管理代理。
