Open a DAC (Dedicated Administrator Connection) There are two steps to recovering from OOM: Still, the best planning does not always foresee what actually happens and you might end up with low memory or OOM. Good planning and monitoring can help avoid OOM situations. Obviously, it is best to not get into a low memory or OOM (Out of Memory) situation. change the value of MAX_MEMORY_PERCENTįor information on maximum values for MAX_MEMORY_PERCENT see the topic section Percent of memory available for memory-optimized tables and indexes.įor information on configuring max server memory see the topic Server Memory Server Configuration Options. See the topic Best Practices using In-Memory OLTP in a VM environment for more information. If the server is running on a VM and is not dedicated, set the value of MIN_MEMORY_PERCENT to the same value as MAX_MEMORY_PERCENT.

This code snippet changes MAX_MEMORY_PERCENT for the resource pool PoolHk to 70% of installed memory. If the value is too low, restore will fail. If the database is bound to a resource pool, which is best practice, the memory available to restore is governed by MAX_MEMORY_PERCENT. Increase the value of MAX_MEMORY_PERCENT. You can restart them following the successful restore.
For this class of issues, use the following measures to make more memory available to the restore operation:īy closing one or more running applications or stopping services not needed at the moment, you make the memory they were using available for the restore operation. If the server does have enough physical memory, but you are still seeing this error, it could be that other processes are using too much memory or a configuration issue causes not enough memory to be available for restore. The server you restore a database to must have enough available memory for the memory-optimized tables in the database backup, otherwise the database will not come online, and will be marked as suspect. When you attempt to restore a database you may get the error message: "Restore operation failed for database ' ' due to insufficient memory in the resource pool ' '." This indicates that the server does not have enough available memory for restoring the database. What to keep in mind when using In-Memory OLTP in a virtualized environment. What to do if you get the error message, "Disallowing page allocations for database ' ' due to insufficient memory in the resource pool ' '." when available memory is sufficient for the operation.īest Practices using In-Memory OLTP in a VM environment Resolve page allocation failures due to insufficient memory when sufficient memory is available What to do if you find low memory issues are negatively impacting performance.

Resolve database restore failures due to OOM See Monitor and Troubleshoot Memory Usage for guidance that can help you avoid many OOM situations.

This topic covers how to recover from an OOM situation. It is possible that the amount of memory you installed and allocated for In-Memory OLTP becomes inadequate for your growing needs. In-Memory OLTP uses more memory and in different ways than SQL Server does.
