Cannot Change Thread Mode After It Is Set Sp_oacreate

The (max) settings above default to "100" and the (min) settings default to "0". This option is very resource intensive and uses large amounts of disk space. In fact, it only exists for backward compatibility with legacy scripts, and changing its value has no effect on SQL Server's behavior. Please try the request again. this content

If the estimated number of rows is greater than 1000, then it will be performed asynchronously. If you are getting memory error about index creation, instead of changing this option and increasing the memory allocated to index creation, perhaps there are other routes you can take. Why? fill factor (1) (2) (3) If you follow best practices for creating and rebuilding indexes, you will manually set the FILLFACTOR option of the CREATE INDEX or the ALTER INDEX statements,

name: This is the name of the configuration option, and you need to become familiar with each one of them. In other words, start running your system using the default, and allow SQL Server to make the best decisions. Unfortunately, this cooperation is sometimes one-sided, with SQL Server often having the greatest influence. It can be.

The job uses Ole automation to gather the disk space usage for the server and email the DBA's when disk space usage is below a predetermined percentage. This option should only be changed if you have determined, through extensive testing, that changing this option provides you the results desired. If your instance doesn't need Database Mail, then leave it off. Now you may be wondering how to go about finding out what these 70-odd settings are for each of your instances, and how should they should best be configured.

For now, leave these settings at their default values, unless told to change them from Microsoft SQL Server Customer Support Services. If you enter your own value, you are telling SQL Server to use a maximum number of locks, and as a result, limit the amount of memory used for locking. Essentially, you want to use the highest value you can for the "max server memory" that when implemented, results in the Available MBytes as described above. The only reason why you might want to increase this value is if there are other processes (such as another SQL Server instance), that might want to steal the RAM from

This is difficult to diagnose and is best left up to an experienced SQL Server expert, or used upon recommendation by Microsoft SQL Server Customer Support Services.

If the statistics are outdated or skewed, the query optimizer may make an incorrect guess. https://www.simple-talk.com/sql/sql-training/how-to-document-and-configure-sql-server-instance-settings/ If your data exceeds this maximum, you will get one of several different messages. This means that you will have a live record of the configuration settings of your instances. 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105 <#This PowerShell routine creates an excel spreadsheet with the current configuration settings of all He works for Microsoft and is intimately familiar with how SQL Server uses memory.

If so, ensure that the data and indexes are aligned, as if they are not aligned, the index creation error can occur. http://electrictricycle.net/cannot-change/cannot-change-thread-mode-after-it-is-set-c.html The minimum value is 512 and the maximum value is 2147483647. If you should purchase a third-party product for SQL Server, installing it may automatically turn this option on for you, or instructions for turning it on may be included with the Your cache administrator is webmaster.

This is not to say that changing this setting might help in some cases, as it can, but the cases where it can help performance are edge cases and should be In other words, if "clr enabled" is turned on, then "lightweight pooling" has to be turned off. Because of this, the easiest way to see the options is to run the following script. 1234 SELECT  *FROM    sys.configurationsORDER BY name ;GO Or, you can run the following script if you like: have a peek at these guys If your server has more than eight physical cores, then set the "max degree of parallelism" to eight.

I can only offer general advice. While single database ownership chains are a standard feature of SQL Server, by default, ownership chaining across different databases on the instance is turned off by default as a way to In addition, because these two options are so critical, we will be spending extra time discussing them.

The "clr enabled" option is mutually exclusive with the "lightweight pooling" option, which will be described soon.

What happens is that SQL Server passes off the data to the network to be sent, and Ethernet networks chop this up into packets up to 1500 bytes in size. This can sometimes help benefit the performance of larger keysets. Amount of RAM Installed Available MBytes < 4 GB 512 - 1024 MB 4-32 GB 1024 - 2048 MB 32-128 GB 2048 - 4096 MB 128+ GB 4096 MB While the For example, if the "backup compression default" option is left at the default "0" value, then if either the BACKUP DATABASE or BACKUP LOG statements are issued without the WITH COMPRESSION

Using WITH COMPRESSION or WITH NO_COMPRESSION will always override the value for the "backup compression default" option. The following recommendations come from Slava Oks's blog. And second, any memory that you allocate for index creation will take away memory from other SQL Server processes, potentially hurting SQL Server's overall performance. check my blog In other words, it is your network, not SQL Server, that really determines the size of packets sent across the network.

But don't worry, buy the time you finish this article, they will all make sense. Of course, if user CLR assemblies are required, then this option must be turned on, set to "1". cost threshold for parallelism (1) (2) (3) As the query optimizer evaluates a query for creating an execution plan on a server with two or more available CPUs, it estimates how awe enabled (1) (2) (3) (5) This feature is depreciated, although it is very useful if you are still running any 32-bit version of SQL Server with more than 4 GM

When "disallow results from triggers" is set to the default value of "0", this means that SQL Server does not permit triggers to return result sets. Whichever method you choose, you will need to perform formal testing to ensure that the final choice you make actually increases performance and doesn't hurt it. SQL Server considers a number of factors when considering how much of the available CPU resources to use during a crawl, but you can influence it by changing this option. For example, let's say that the full crawl is scheduled during a time when the instance is not very busy.

First, how much memory should you allocated?
