The first of all is, when you go to a customer for a simple upgrade to SharePoint 2010 isn’t going to be easy. Why, well Rick Taylor is one of the masters of upgrading to SharePoint 2010, and now I know why he is preaching about all the mess you going to have with upgrading to SharePoint 2010.

A simple thought about upgrading isn’t going to be, why? Every customer has custom solutions, changed css’s or anything of that stuff, but it’s going to be worse. When you have Site Definitions, what is not the best practice of course it is going to be alot worse. All kinds of developers are writing and developing nice Site Definitions but when you are at the stage you want to upgrade these developers kan start all over again. Yes, because they put everything in a solution. Every complete customized lists, document libraries and blogs.

Wow, well if you are an architect or a business manager and you hear about Site Definitions and you’re upgrading to SharePoint 2010. You can think twice, and even need to save some money to hire a developer that can write all the site definitions again which are not best practice off course. Yes, why I am writing this blog, because I just started to upgrade some solution that is written if all the above mess. Customized blog pages, document libraries, lists, etc. Yes we make features and we make site definitions and we put them all in one bucket called a WSP and hopefully it will work under SharePoint 2010, because you’ll never know.

In the last couple of years I installed alot of different farms for SPS2003, MOSS 2007 and yet I started with the installation of MSS 2010.
Most organizations started using Virtualization software like VMWare ESX of other virtualization software. As far as I know I had to most problems with MOSS 2007 on virtual boxes. The most problems where database servers or badly configured boxes.

When you’re using SQL Server or other database server you’ll will see that when they are bad configured your farm is performing very very bad. Why?

One of the biggest reasons is that when you’re running a database direct on a Virtual Hard Drive it will not perform as well. Why? Mostly the vhd’s are using the same LUN on a SAN or physical disk. The best option here is to use pass-through disk to a LUN on a SAN.

Second when you’re running a DB server on a Virtual Box and you allocate shared memory and shared CPU’s it will also cost performance. This is also for MOSS or SP2010. You should use one-on-one CPU. So if you need 4 virtual CPU’s you’ll also need 4 cores and not sockets. For another example check your NUMA(Non Uniform Memory Access).

If you have a virtualbox with 8 cores and 32 GB of memory then your NUMA is 4 GB. So you can maximum allocate 4 GB of memory to a virtual server. If you allocate more memory it can cost your performance.

If your using VLAN’s and you have multiple Virtual Switches ensure that your MOSS or SP2010 environment is using the same Virtual Switch. If the latency is higher then 1ms your performance will drop. MOSS and SP2010 will only have a good performance with a very low latency.

Also if you’re running an AD server and this server is also running poorly your SharePoint environment will also perform poorly. SharePoint authenticates alot.

Most hardware performance issues are written above. Look at it when you’re making SharePoint environment virtualized. 80% of the problems are the DB server of the Indexing Server of your SharePoint environment.

For a company I work for we have an different kind of situation regards the SharePoint site. We have a DMZ with all the webservers we need. We also got a small MOSS 2007 farm where the company hosts his two SharePoint sites. Both sites are on the same farm and on the intranet it works perfectly.

On of these sites is hosted normally on the http port, and the other on is hosted as an extranet application on the https port. The site hosted on the public http port is good, and doesn’t show any problems.

The certificate for the private site is at the reverse proxy server, although it is also a kind of firewall. We used the technet documentation for implementation (link). We did use the Alternative Access Mappings and we did redirect our https port(proxy) to the http port(Site farm).

Everything works perfectly, except for the Document Library. Normal documents can be opened without any problems, but when you want to access a folder in the document library we got a permission denied error from the proxy server. Why you may ask? Well the document library has folders and show all http:// instead of https://. So it redirects from an secure site into a insecure site were the port is blocked on the DNS.

So we maybe thought that this was related to the firewall instead of SharePoint, well forget that. The problem resists in the Document Library and nothing else. Now we contact Microsoft for this issue, but the problem is that Microsoft has only helpdesk people with knowledge of SharePoint or ISA Server. Microsoft helpdesk wants to relate the problem to the firewall instead of their own product, and I can’t blame them, because it’s their product. Well I’m not happy at all with this, because we won’t change anything in the firewall. We tried everything there is needed to work.

The company were I work for doesn’t have this problem to Exchange Server 2003, and this is the same kind of product, and they have the exact same rules and same implementation… Probably this a bug (or feature) and they can’t solve it… maybe later on…

Well I will keep you informed… when I have a solution my blog will keep you informed about it…

I discovered a problem with the My SharePoint-Sites. Someone at the company I work for discovered that he had alot of sites in his SharePoint-Sites webpart at his My Site. So that shouldn’t be a problem I thought. Well it was…

I deleted a subsite of our company intranet, because we decided that the site needed his own dns and database, because it was growing to large. After two weeks we found out that the SharePoint-Sites didn’t update and when we hitted on of these sites we got an error. So, I thought it was maybe a My Site related issue. I deleted his My Site, because it didn’t have alot of information on and added his My Site to new.

Still the same problems came forward, so I decided to hit google.com for it. Well maybe I didn’t seek good enough, but maybe it was related to the search engine. So I decided to reset all the crawled content. After an hour I checked back on the My Site, but still the same problem exists.

Allright, so I decided to look in the help of the stsadm utility. Things that could help I sought on google.com. Well after a couple of searches I found out the following command:

stsadm -o sync -deleteolddatabases 0

In the ssp database you have the table ’sitesynch’ and holds the information for all synchronized information over your SharePoint sites and My Sites. This article mentioned also that sometimes the synchronization table isn’t sychronized. Well after an hour I checked back at the My Site and saw that the SharePoint-Sites didn’t appear anymore.

The job related to this is the â œProfile Synchronizationâ timer job
