powershell远程检查多个oracle数据库表空间使用率
作为一个大中企业的DBA，要面对众多大中小多个数据库，除了及时发现异常问题，还要及时了解数据库表空间占用率，掌握空间增长速度过快情况，防止数据库空间不足。本程序用powershell语言编写，通过配置文件所列清单，对数据库实例进行远程访问，获得除undo和临时表空间外其它表空间使用率，并按使用率进行由大到小的排序。
本程序将先检测IP地址和端口侦听是不是正常，如果数据库实例无法远程访问，见及时继续下一个数据库实例，而不会无限等待。
最主要的是将检查结果显示为html页面的一个表格内，使得检查结果直观，方便结果检查。
以下为程序源代码：
Add-PSSnapin VMware.VimAutomation.Core
function filestring-search($inputFile,$matchstring,$matchcount){
$tmpcontent = Get-Content $inputFile
for($i=0;$i -le $tmpcontent.length;i++)
{
if($tmpcontent[$i] -like '*异常*'){
$matchcount++
wite-host matchcount: $matchcount-background red
}
}
return
}

Include a link in your cell.Other text is allowed in

Example:

This tag uses a picture which you can click on and go to the
specified link.You must specify the> url where it is located, this information is seperated by semi-
colons.Other text is allowed in the string, but the tag
must be at the end of the string.
Example:

Bar graph makes a simple colored bar graph within the cell.The
length of the bar is controlled using .You can
designate the color of the bar, and the color of the remainder
section.Due to the mysteries of HTML, you must designate a
> So if you had a percentage of 95, say 95% used disk you
would want to highlight the remainder for your report:
Example:
5% free
What if you were at 30% of a sales goal with only 2 weeks left in
the quarter, you would want to highlight that you have a problem.
Example:
30% of goal
.PARAMETER InputObject
The object you want converted to an HTML table
.PARAMETER HeadWidth
You can specify the> and are passed to the parameter in array format.Each element
in the array corresponds to the column in your table, any element
that is set to 0 will designate the column with be dynamic.If you had
four elements in your InputObject and wanted to make the 4th a fixed
> -HeadWidth 0,0,0,600
.PARAMETER CSS
Designate custom CSS for your HTML
.PARAMETER>
Specifies a> .PARAMETER PreContent
Specifies text to add before the openingtag. By default, there is no text in that position.
.PARAMETER PostContent
Specifies text to add after the closingtag. By default, there is no text in that position.
.PARAMETER Body
Specifies the text to add after the openingtag. By default, there is no text in that position.
.PARAMETER Fragment
Generates only an HTML table. The HTML, HEAD,> .INPUTS
System.Management.Automation.PSObject
You can pipe any .NET object to ConvertTo-AdvHtml.
.OUTPUTS
System.String
ConvertTo-AdvHtml returns series of strings that comprise valid HTML.
.EXAMPLE
$Data = @"
Server,Description,Status,Disk
Server1,Hello1,Up,"55% Free"
Server2,Hello2,Up,"65% Used"
Server3,Goodbye3,Down,"5% Free"
server4,This is quite a cool test,Up,"Test Images"
server5,SurlyAdmin,Down,"The Surly Admin"
server6,MoreSurlyAdmin,Updating,"http://thesurlyadmin.com"
"@
$Data = $Data | ConvertFrom-Csv
$HTML = $Data | ConvertTo-AdvHTML -HeadWidth 0,0,0,600 -PreContent "This might be the best report EVER" -PostContent "Done! $(Get-Date)" -Title "Cool Test!"
This is some sample code where I try to put every possibile tag and use into a single set
of data.$Data is the PSObject 4 columns.Default CSS is used, so the tag
will not work but I left it there so you can see how to use it.
