As the builds progress we have gotten more and more wait_types

These where the number of wait_types in each version so far

  • 202 SQL Server 2005
  • 484 SQL Server 2008
  • 490 SQL Server 2008 R2
  • 631 CTP3
  • 646 RC0 (15 more as listed below)

These 15 are the ones I have not encountered before in any pre 2012 RCO builds - What are they ??

[Sorry] For now I just can't tell you as I simply do not have the resources to fully explain their purpose { Some of their purpose can be deduced by its name }

and none of these as yet show me any values other than 0 (zero)

 

Select *

from sys.dm_os_wait_stats

WHERE Wait_type in

('DTCPNTSYNC','HADR_CONNECTIVITY_INFO','HADR_FILESTREAM_FILE_CLOSE','HADR_SYNCHRONIZING_THROTTLE'

,'HADR_TIMER_TASK','PREEMPTIVE_HADR_LEASE_MECHANISM','PWAIT_EVENT_SESSION_INIT_MUTEX','PWAIT_REPLICA_ONLINE_INIT_MUTEX'

,'RESOURCE_GOVERNOR_IDLE','SCAN_CHAR_HASH_ARRAY_INITIALIZATION','SP_SERVER_DIAGNOSTICS_BUFFER_ACCESS'

,'WAIT_XTP_GUEST','WAIT_XTP_TASK_SHUTDOWN','WAIT_XTP_TRAN_COMMIT','XTPPROC_PARTITIONED_STACK_CREATE')

As I learn more and try out the AlwaysON feature I’m sure some of these may start to show some numbers

SQL Server like other software unfortunately has bugs, and thankfully these are often resolved in the subsequent Service Packs & Hotfixes released

One such bug was the incorrect growth of the log file, if the growth increment was any multiple of 4GB - it doesn't grow with the expected growth size

 

For those who didn't know

As log growths are split in a number of equally sized number of VLFs, with that number of VLFs dependent on the overall growth increment size

For a growth increment that is less than 64MB, this will grow the file in 4 VLFs (equally sized), and with a growth increment size between 64MB to 1GB this is in 8 VLFs, finally for the growths > 1GB this is in 16 VLFs


Paul Randal blogged on this bug way back in May 2010 - that's when I learned about the 4GB increment issue

http://www.sqlskills.com/BLOGS/PAUL/post/Bug-log-file-growth-broken-for-multiples-of-4GB.aspx

I recommend that you also read this entry VLFs by Kimberly http://www.sqlskills.com/BLOGS/KIMBERLY/post/Transaction-Log-VLFs-too-many-or-too-few.aspx#ixzz1lXeN9jNy

Subsequently my growths have been primarily in 2GB Growths, thus 16 VLFs each being 128MB (Once this hotfix is in place I can perhaps use the 4GB interval I want larger VLFs)

Finally a Connect item can help highlight such issues and ultimately even get us a fix - I try to review these regularly and vote for those you agree should be resolved

http://connect.microsoft.com/SQLServer/feedback/details/481594/log-growth-not-working-properly-with-specific-growth-sizes-vlfs-also-not-created-appropriately


Well for SQL Server 2008R2 this is being now addressed with the SP1+CU4 or CU11, details are documented in this KB http://support.microsoft.com/kb/2633151

It doesn't seem that there is also a fix for SQL Server 2008 - if this does become known I blog those details also

Things are getting real BUZY for me on the SQL Events front already {I have plans to do a lot of SQL Events this year, to even try to match my huge 2011 tally)

I have to try to find time to plan and organize all the various tasks needed to just fit it all in {need to get my travel plans sorted .I will have to try using Tripit as Jen Stirrup has recommended

and I still need to find a few evenings to run some local User-Group events in London over the next few months

I'm Looking for companies to be hosts for our User-Group evenings - So would you like to have a SQL User-Group event in London @ your own location (Ideal for your SQL Team to attend)

it just needs a room capable of seating 30-100 people for ~ 3 hours (6-9PM) during a mid-week evening (Tuesday - Thursday's) and not be difficult for the attendee's to get to.. close to a tube station (within 5-10 minutes) is always helpfull

We'll provide the speakers (you can help choice the topics for the evening) and we also provide the dinner & refreshments + SWAG for the attendee's - interested please email me @ Neil.Hambly@Hotmail.co.uk

 

So with this many event's already in my Calendar over the next few Months, it is going to be very exciting time but a tad exhausting as well

I will get to see so many of my SQL Friends over these events and undoubtedly meet a few new ones

As some of you probably know - I do speak a lot of SQL conference's, but getting session submissions picked can be tough @ times (especially for the larger events)

Sometimes there are community voting rounds .. for a few precious slots @ these larger events

 

I now have one of those voting rounds for my Pre-Con submission @ the next SQLRally event May 8th -  May 11th  in Dallas, TX  (this is one of the largest SQL Conferences)

My Pre-Con submission "Performance Trace & Event Collection in SQL Server" was selected for the voting round (that in itself is a big deal)

 

So please can I kindly ask if you can you spare just a minute of your time  & vote for my session

(it will be tough competition to secure one of the spots)

http://www.sqlpass.org/sqlrally/2012/dallas/CommunityChoice.aspx

Just Login (free to register if not already a member) and selected the session(s) you want to vote for - The voting ends 9th Feb 5PM (CST)

 

For those interested my upcoming confirmed events I'll be presenting @ (some outside of UK) as follows
