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

}

Function ConvertTo-AdvHTML

{ <#

.SYNOPSIS

Advanced replacement of ConvertTo-HTML cmdlet

.DESCRIPTION

This function allows for vastly greater control over cells and rows

in a HTML table. It takes ConvertTo-HTML to a whole new level! You

can now specify what color a cell or row is (either dirctly or through

the use of CSS). You can add links, pictures and pictures AS links.

You can also specify a cell to be a bar graph where you control the

colors of the graph and text that can be included in the graph.

All color functions are through the use of imbedded text tags inside the

properties of the object you pass to this function. It is important to note

that this function does not do any processing for you, you must make sure all

control tags are already present in the object before passing it to the

function.

Here are the different tags available:

Syntax Comment

===================================================================================

[cell:] Designate the color of the cell. Must be

at the beginning of the string.

Example:

[cell:red]System Down

[row:] Designate the color of the row. This control

can be anywhere, in any property of the object.

Example:

[row:orchid]

[cellclass:]

Designate the color, and other properties, of the

cell based on a class in your CSS. You must

have the class in your CSS (use the -CSS parameter).

Must be at the beginning of the string.

Example:

[cellclass:highlight]10mb

[rowclass:] Designate the color, and other properties, of the

row based on a class in your CSS. You must

have the class in your CSS (use the -CSS parameter).

This control can be anywhere, in any property of the

object.

Example:

[rowclass:greyishbold]

[p_w_picpath:]

Include an p_w_picpath in your cell. Put size of picture

in pixels and url seperated by semi-colons. Format

must be height;width;url. You can also include other

text in the cell, but the [p_w_picpath] tag must be at the

end of the tag (so the alternate text is last).

Example:

[p_w_picpath:100;200;http://www.sampleurl.com/samplep_w_picpath.jpg]Alt Text For Image

[link:] Include a link in your cell. Other text is allowed in

the string, but the [link] tag must be at the end of the

string.

Example:

blah blah blah [link:www.thesurlyadmin.com]Cool PowerShell Link

[linkpic:]

This tag uses a picture which you can click on and go to the

specified link. You must specify the size of the picture and

url where it is located, this information is seperated by semi-

colons. Other text is allowed in the string, but the [link] tag

must be at the end of the string.

Example:

[linkpic:100;200;http://www.sampleurl.com/samplep_w_picpath.jpg]www.thesurlyadmin.com

[bar:]

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

width for the column with the [bar] tag using the HeadWidth parameter.

So if you had a percentage of 95, say 95% used disk you

would want to highlight the remainder for your report:

Example:

[bar:95;dark green;red]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:

[bar:30;darkred;red]30% of goal

.PARAMETER InputObject

The object you want converted to an HTML table

.PARAMETER HeadWidth

You can specify the width of a cell. Cell widths are in pixels

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

width--this is required for using the [bar] tag--of 600 pixels:

-HeadWidth 0,0,0,600

.PARAMETER CSS

Designate custom CSS for your HTML

.PARAMETER Title

Specifies a title for the HTML file, that is, the text that appears between the `n"
