regex - 从命令输出中解析 WebSphere JVM 名称的 Windows 脚本

Question

我正在编写一个(批处理文件或 VBScript)来很好地关闭 Windows 服务器上所有正在运行的 WebSphere JVM，但需要一些文本处理方面的帮助。我希望脚本运行并解析“serverstatus”命令的输出以获取框中的 Application Servers 名称并将匹配项(带回车符)存储在用于脚本其余部分的变量。

示例命令输出:

C:\WebSphere\AppServer\bin>serverstatus -all
ADMU0116I: Tool information is being logged in file
       C:\WebSphere\AppServer\profiles\MySrv01\logs\serverStatus.log
ADMU0128I: Starting tool with the MySrv01 profile
ADMU0503I: Retrieving server status for all servers
ADMU0505I: Servers found in configuration:
ADMU0506I: Server name: MyCluster_MySrv01
ADMU0506I: Server name: MyCluster_MySrv01_1
ADMU0506I: Server name: MyNextCluster_MySrv04
ADMU0506I: Server name: MyNextCluster_MySrv04_1
ADMU0506I: Server name: nodeagent
ADMU0508I: The Application Server "MyCluster_MySrv01" is STARTED
ADMU0508I: The Application Server "MyCluster_MySrv01_1" is STARTED
ADMU0508I: The Application Server "MyNextCluster_MySrv04" is STARTED
ADMU0509I: The Application Server "MyNextCluster_MySrv04_1" cannot be
       reached. It appears to be stopped.
ADMU0508I: The Node Agent "nodeagent" is STARTED

*nodeagent 不应匹配。对于我是要定位所有应用服务器还是只定位那些状态为“已启动”的应用服务器，目前还没有定论。

这是使用 Regex 的替代方法。它只是读取 stdout 并处理所有启动的应用程序服务器——应用程序服务器存储在一个名为 AppServers 的数组中。在 W2K3 上测试。编辑:我们通过添加日志写入功能添加了一种将输出记录到文件的方法(不要忘记在我们刚刚添加到此答案的脚本开头添加 const ForAppending)。日志写入函数采用以下格式:

Logwrite "some text to write - delete file if exists", "c:\Path\filename.txt", 1
Logwrite "some text to write - append to file, don't delete", "c:\path\filename.txt", 0

这是一个粗略的功能，但可以满足您的要求。我希望这有帮助。 :)

Const ForAppending = 8

MaxAppServers = -1

' While we're looping through the response from the serverstatus command, look for started application servers
' and store them in an ever expanding array AppServers.
' The Variable MaxAppServers should always contain the highest number of AppServers (ie: ubound(AppServers))

While Not objStdOut.AtEndOfStream
   strLine = objStdOut.ReadLine
   If InStr(LCase(strLine), "admu0508i: the application server """) Then

      ReDim Preserve AppServers(MaxAppServers)
