SQL Server - Need Bigger Log Files grow faster local NVME Storage

Say you wanted to grow the transaction log of a database from a few hundred megabytes to 100GB or even 500GB on 2 striped 1.73TB NVME drives in a 4 disk pool using Storage Spaces direct.  First this is something you would NOT normally do, but if you had some some time on a new fast server these are the sort of fun crazy things you do in your spare time.  Simple math shows that the Local NVME storage was 2.2 Times faster than the SSD SAN based storage connected over 40Gb FCoE.

In this example: I grew the log file 500GB on an I3 AWS Local NVME instance that took 8 Minutes and 32 Seconds



In this example: I grew the log file 100GB on a Dell Compellent SC8000 with an SSD backed lun that has around 15k Write and 30K Read IOPS taking around 3 minutes and 55 Seconds

How to mass update all or some sql server agent job step commands

How to mass update all or some sql server agent job step and commands using TSQL.   This will use the built-in Replace function to search text in SQL agent jobs  SQL Agent Job information is stored in MSDB and can reviewed using some of the following queries: SELECT * FROM msdb.dbo.SysJobs SELECT * FROM msdb.dbo.SysJobSteps -- OR SELECT a.name as job_name, b.step_name, b.subsystem, b.command, b.database_name, a.enabled       ,a.description, a.date_created, b.job_id, b.step_id   FROM [dbo].[sysjobsteps] as b   INNER JOIN sysjobs as a ON a.job_id = b.job_id Since I will be focusing on the Commands column I will look at using this query to extract data into a temp table so that I can test any updates with the replace step before doing an update to MSDB. This would be your opportunity to archive or save any commands as needed.  Some people may prefer to generate all the syntax necessary to use EXEC sp_update_jobstep so you a...

SQL Monitoring for Blocking and Locking Capture and Log to table with sp_WhoIsActive or sp_BlitzWho

Image
You can use  sp_WhoIsActive or sp_BlitzWho and log the capture data to a table.   In my example I will use sp_whoisactive as I am more familiar with its use and data collection, however I will look at creating a future post using BlitzWho.  I will provide a few examples that were used to determine that the paid SQL monitoring products can be fancy tools but can be useless if you don't understand the basic concepts or even an understanding of how we capture similar data or in some cases more finely tuned to a specific scenario or use case.  Sometimes these paid solutions are incorrect or things can simply go wrong (Services Fail to start or the data is aggregated and misses something like the query commands and SQL Fragments) and it's always good to plan ahead and be prepared.   Sp_WhoIsActive is a procedure written by Adam Machanic. It can be found here:  sp_whoisactive downloads Sp_BlitzWho is a procedure written by the Brent Ozar team....

SQL Server General Index Naming Convention

SQL Server General Index Naming Convention  easy to follow:  PK_ for primary keys PK_  Primary Keys, which are logical constructs and not necessarily physical constructs, get tagged with a PK_ prefix. In most systems that I design the PK_ isn’t a clustered index.  IX_ for non clustered non unique indexes IX_  standard single or even multi-column indexes used for seeks or intersection just get prefixed with an IX_ (for  I nde X ). In cases where I need a composite index (i.e., multiple columns) but still explicitly ‘tolerate’ key/bookmark lookups, I’ll still call my seek/intersection/composite indexes IXes. UK_ for unique keys UK_  for unique key index UX_ for unique indexes UX_  for unique index. CLIX_ for Clustered Index (non PK) CLIX_  (non-PK) Clustered Index name is prefixed with CLIX (for  CL ustered  I nde X ) Additionally, I like to code all Create Indexes in SQL 2012 and above with an if not ...
