The tempdb metadata tables can live in memory, and four short steps tell you whether yours do. This post checks the setting, shows how to turn it on and off, and counts the tables SQL Server moves. It also says when the feature is worth a restart.
Memory-Optimized Files: List Logical and Physical Names
To list memory-optimized files, join sys.dm_db_xtp_checkpoint_files to sys.database_files. This post builds a small memory-optimized database, shows the container’s logical and physical name and counts its checkpoint files by type and state. It also explains why a container holds far more disk space than its data uses.
In-Memory OLTP Migration Checklist: Which Features Block You
An In-Memory OLTP migration checklist from SSMS lists the tables and procedures the engine will refuse. This post tests those refusals on SQL Server 2025, shows which old limits are gone, and adds a query that finds blockers in your own database.
SCHEMA_ONLY vs SCHEMA_AND_DATA for Memory-Optimized Tables
Compare SCHEMA_ONLY and SCHEMA_AND_DATA memory-optimized tables, inspect logging and recovery, and test an isolated offline-online cycle.
SQL SERVER – Natively Compiled Stored Procedures and Location of Compiler
I recently implemented a Memory Optimized Table solution at one of the large financial organizations while working on Natively Compiled Stored Procedures.
Error 41368: Memory-Optimized Tables and Transactions
Error 41368 appears when an explicit transaction reads a memory-optimized table at the read committed level. This post reproduces the error, fixes it with a table hint or a database option, and shows the two related errors that the fixes do not cure. It also answers what the option changes for other tables.
MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT: How to Check It Is On
MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT is a database option, so DBCC USEROPTIONS never shows it. This post reads the option from sys.databases and from DATABASEPROPERTYEX, turns it on in a demo database and finds every database that has it. It also shows a guarded script you can reuse in deployments.
