Cluster resource SQL Server (InstanceName) failed to come offline
Recently I added some additional memory to a sever thats part of an active
passive cluster (for a total of 8GB). After which we started receiving an
error message when trying to move the cluster over to the passive server:
Source:ClusSvc
Event ID: 1117
Description: Cluster resouce SQL Server(InstanceName) failed to come offline
I did some searching online but the only thing I could find was a thread on
google news from October 2003 (link included below). I am wondering if
anyone else has also experienced this particular problem and if so how they
may have solved it.

Anything in the SQL Error log?
Did you re-configure SQL to use the additional RAM?

|||The error message indicates that the SQL Server recource fail to come offline. Instead of moving the group, try taking the SQL Server resource offline and see the results/errors ? If it goes offline then I would take all
resources in the SQL group offline, move the group to the other node and bring one resource online at a time -- starting with the resources that are not dependent on any resources i.e the disks first followed by sql ip
resoruce, sql network name and then sql server. Also, I will uncheck "restart" property for the resources to troubleshoot this issue (set it back to default after issue is resolved).
NOTE: Since AWE is enabled, max server memory is set to 7GB and passive node has 4GB, when you move the SQL Group to the passive node, SQL server instance will acquire almost all of the available memory
and leave ONLY up to 128MB fo memory free. For more info, please refer to SQL Server BOL topic "Managing AWE Memory".

Client Side Cursor vs Sever Side Cursor?
I need a way to scroll through a recordset and display the results
with both forward and backward movement on a web page(PHP using
ADO/COM)..
I know that if I use a client side cursor all the records get shoved
to the client everytime that stored procedure is executed..if this
database grows big wont that be an issue?..
I know that I can set up a server side cursor that will only send the
record I need to the front end but..
Ive been reading around and a lot of people have been saying never to
use a server side cursor because of peformance issues.
So i guess im weighing network performance needs with the client side
cursor vs server performance with the server side cursor..I am really
confused..which one should I use?

Not sure why you would need anything else other than a forward only
recordset on a website. Unless you are planning on persisting the recordset
for the session and then navigating back and forth thru it.

Please note that your "Client" in this case would be the web server and not
the actual end users browser.

Does your web server (IIS or Apache) reside on the same physical server as
the database?. I would think that the performance issues would come from the
network trip hit. But if the web server and database are on the same
physical server, then this wouldn't matter.
Personally, I don't like the idea of returning 1,000,000 records just to
display 20 at a time. Nor do I think you can keep a connection/recordset
alive in between web pages without severaly affecting scalability.
You may want to do a search on this newsgroup thru google groups for other
paging techniques that will return only the results the user needs.
