MS20331 Core Solutions of Microsoft SharePoint Server 2013 Training – Day 3

Third day of the training was mainly about SharePoint cache and configuring SharePoint services.

\n\n

Documents in libraries an elements in lists.
Libraries and Lists.
Child sites.
Site Collection. Defines web path and creates Root Site. Has own DB (could be separate)
Web Application. SQL DB – one per web app.
Path Based and Host Named site collections (russian):
Block file upload by extension (check extensions only) – CA > Manage Web Applications > Select Application > Click “Blocked File Types” on Ribbon
Big files upload settings. CA > Manage Web Applications > Select Application >  General Settings button on the ribbon > Maximum Upload Size (default 250 MB). For list items web.config
Both of aforementioned settings go to web config?
To create test files fsutil can be used:
fsutil file create new <filename> <lenght>
SP cold start issue. Warm up scripts.
Fiddler to test difference with and without warm up scripts
SP can be configured for anonymous access:
1. Enable anonymous access on Web App level. CA > Manage Web Applications > Authentication Providers button on the ribbon (verify in IIS)
SP Site Permissions Management.
1. Site Permissions.
Around 50 individual permissions for certain actions
Permission levels (groups of individual permissions) – Visitors, Participants, Owners etc. New levels can be created.
Permissins can be assigned to AD user account (or other user account) or AD groups or alternatively SP groups can be created (valod on site collection leve;)
Whichever method, or methods, you use to authorize user access to SharePoint objects in your environment, it is independent of the userauthentication mechanism you use because SharePoint 2013 converts all authenticated users into a SharePoint User object (SPUser).
Permissions inheritance/level: Site Collections, Sub Site, Libraries, Elements
Best practice – move on site collection level all content which should be accessible for all
In case you forgot how to create sites/subsites:
Revoke/deny access for particular user – Policy for Web Application
SP cache to alleviate load on SQL, network and SP app servers. Caching removes/minimizes queries to SQL.
If misconfigured caching can lead to perfrormance degradation. Mostly cach is disabled by default.
4 types of cache:
1. Blob cache (stores JS, CSS and pictures on WFE). Each WFE has its own BLOB cache. Cache penalty – 1st query is slower when using cache. If file accessible anonymously it speed things up as there is no neeed to check permissions. BLOB cache optimized for sites anonymous. Extra RAM consumption – extra 800 bytes per file (for index)
BLOB cache configuration: change web.config, BlobCache settings – location, file types, max size in GB
2. Output cache. Requires activation of SP Publishing Feature. Only Publishing pages go into this cache. Being stored in RAM. If disabled constant stream of F5 page refresh request may lead to significant load on SP server. Cache handling: TTL OR Cache being discarded if content changed on site. Each page takes 2x page size + 32 KB in RAM.
You can create cache profiles. E.g. for static content (like final version of article) set TTL, for changing change check.
Create Publishing site and enable SIte Output cache in Site Settings.
3. Object cache. Enabled by default and can not be disabled (navigation, search query box), but has to be configured (you may see warning event about this upon each IIS startup – event ID 7363). Configured after starting “Share Point Publishing Feature”
\n\nOpen a shell

Execute the following commands:\n\n[code language=”powershell”] \n#1\n$wcm = Get-SPWebApplication -Identity http://[webappurl/] \n#2\n$wcm.Properties["portalsuperuseraccount"] = “DOMAINsp_superuser”\n#3\n$wcm.Properties["portalsuperreaderaccount"] = “DOMAINsp_superreader”\n[/code]\n\n

SharePoint 2010: Event ID: 7362: The super user account utilized by the cache is not configured:
4. Distributed cache. Introduced in SP2013. Aka App Fabric Cache. Enabled by default and can be turned off. By default can use 10% of RAM.

\n\n[code language=”powershell”]\n#Check distibuted cache status on node:\nUse-CacheCluster</div>\nGet-CacheHost\n#Check cache host config:\nGet-CacheHostConfig SERVERNAME 22233</div>\n[/code]\n\n

LowWatermark: Percentage of memory usage (from Size) when *expired* items are removed (evicted) from cache if expiration is enabled.
HighWatermark: Percentage of memory usage (from Size) when *all* items may be removed (evicted) from cache if eviction is enabled.
Reference:
You may verify your cache using Performance Console on SP Server (perfmon) – report view and cache counters
SharePoint 2010 cache overview document from MS (no Distributed Cache coverage due to obvious reasons):
Use iisreset /noforce to avoid cache index corruption

SP Services
CA > Manage Services on server
A few services can be Started and Stopped without extra configuring, those run on WFE
Other – Application Services
What Service?
Where it will be run?
Start?
Service Application
Example – configuring Excel Services
For Excel Services managed account you have to grant SPAccess right on content DB in SQL.
You also have to make sure that service not only created but also binded to site (CA > Application Management > Service Application sections > Service Application Associations)
Proxy Group
When you create a service application in SharePoint 2013, a service application connection is created. A service application connection is also referred to as an application proxy. A service application connection associates the service application to Web applications via membership in a service application connection group (also referred to as application proxy group).
SP Admin Site becomes hidden in IIS if service stopped
Get-SPServiceInstance | Where-Object {$_.TypeName -eq “Central Administration”} | Start-SPServiceInstance -Verbose
