My SharePoint Experience: October 2013

שלום חברים

היום חקרתי בעיות עומס וביצועים, בזמן שאנשים מנסים לנווט לדף הבית באתר שלהם.

לאחר שעמוד חדש פובלש זמני טעינת האתר התחילו לגדול באופן דרמטי או לחילופין בקשות דפים לא סיימו את הטעינה בכלל. אתם תראו "שגיאה צפויה אירעה" הידועה לשמצה.

תוכלו לראות שגיאות ביומן ULS לאחר שמשתמש פרסם דף ולאחר מכן מנסה לפתוח את הדף:

" System.Data.SqlClient.SqlException: Transaction (Process ID 76) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

עם העדכונים של אפריל 2013 CU או כל CU אחרי אפריל 2013 (Service Pack 2. וכו ') ניתן לפתור בעיה זו. ניתן להוריד CU + SP2 מכאן

לאחר התקנת העדכון שך אפריל 2013 CU או כל CU אחרי אפריל 2013 תצטרכו להריץ את הקוד הזה ב- Management Shell של SharePoint :

# Set the Problematic Site Collection

#-----------------------------------------------------

param($url = $(Read-Host -Prompt "SiteCollection Url")) # Change the Value between the quotes

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

# Log Function

#--------------------

$Logfile = "C:\duplicates_log.txt"

Function LogWrite

{

Param ([string]$logstring)

Add-content $Logfile -value $logstring

}

# Utility Functions

#---------------------------

function tryDeleteNode

{

param($node,$dictionary,$nodeCollection)

$title = $node.Title

if(!$dictionary.ContainsKey($title))

{

$dictionary.Add($node.Title,$node.Url)

}

else

{

if($dictionary[$title] -eq $node.Url)

{

if($node.Children.Count -eq 0)

{

echo " -> Deleting Duplicate Node: $title"

$nodeCollection.Delete($node)

$global:didDelete= $true

$temp = (get-date).ToString() +";"+ ($site.Url) +";"+ ($title)

echo "$temp"

LogWrite $($temp)

}

else

{

echo " -> Dupe Node $title has children, Skipping..."

}

else

{

echo " -> Duplicate title $title found, but mismatched link, Skipping..."

}

function deleteNodesRecurse

{

$nodes = @{}

foreach($node in $quickLaunch)

{

$childNodes = @{}

foreach($child in $node.Children)

{

tryDeleteNode -node $child -dictionary $childNodes -nodeCollection $node.Children

}

tryDeleteNode -node $node -dictionary $nodes -nodeCollection $quickLaunch

}

function deleteGlobalNodesRecurse

{

$nodes = @{}

foreach($node in $gnavNodes)

{

$childNodes = @{}

foreach($child in $node.Children)

{

tryDeleteNode -node $child -dictionary $childNodes -nodeCollection $node.Children

}

tryDeleteNode -node $node -dictionary $nodes -nodeCollection $gnavNodes

}

# The Program Start Here !

#-------------------------------------

$sitecoll = Get-SPSite $url

write-host "SiteCollection: " $sitecoll.URL -foregroundcolor Yellow

foreach ($site in $sitecoll.AllWebs)

{

write-host " -> Site: " $site.URL -foregroundcolor Green

{

$quickLaunch = $site.Navigation.QuickLaunch

$global:didDelete = $false

deleteNodesRecurse

$pub= [Microsoft.SharePoint.Publishing.PublishingWeb]::GetPublishingWeb($site)

$gnavNodes = $pub.Navigation.GlobalNavigationNodes;

deleteGlobalNodesRecurse

}

while($global:didDelete)

$site.Dispose()

}

$sitecoll.Dispose()

זהו זה, סיימתם !

בהצלחה !

רון נס.

Hello Friends

Today I was asked to explore Load and Performance Problems, It's when people are trying to Navigate to the Home Page in their site.

After publishing a new page the site load times start to increase dramatically or page requests don’t finish loading at all. You will see the infamous “An expected error has occurred“-error or if the callstack is enabled and custom errors are turned off in the web.config (CallStack="true" / customErrors mode="Off") you will see a "Request timed out." error-message.

Errors you will see in the ULS log after a user has published a page and then tries to open the page / site containing the page:
