Memory Used By Database

The Memory Usage report provides a breakdown of how SQL Server allocates memory. This report helps database administrators analyze memory distribution, identify potential memory pressure, and optimize SQL Server performance.

Report Sections:

This report contains two primary components:

1. Memory Allocation Visualization
   • A graphical representation of memory distribution across SQL Server components.
   • Larger areas represent components consuming more memory.
2. Detailed Memory Usage Table
   • Lists SQL Server memory consumers, including available memory, memory clerks, and databases.

Report Columns:

• Row – The row number in the report.
• Object Name – The SQL Server component using memory (e.g., SQL OS, MEMORYCLERK_SQLCLR, tempdb).
• Pages – The number of memory pages allocated to each component.
• Memory (MB) – The amount of memory (in megabytes) allocated.
• Memory (Percent) – The percentage of total memory allocated to each component.

Understanding the Report:

• Available Memory – Displays how much memory remains unused, which can indicate whether SQL Server has sufficient resources.
• SQL OS – Represents memory used by SQL Server’s operating system functions.
• Memory Clerks – Shows memory allocated to specific SQL Server functions, such as query execution, caching, and extended procedures.
• Databases – Displays memory usage for specific databases (e.g., tempdb, Resource DB, DBHealthHistory).

Recommended Actions:

• Monitor Available Memory – If available memory is low, consider increasing SQL Server’s memory allocation.
• Analyze High Memory Consumers – Identify components consuming excessive memory and optimize them.
• Check tempdb Usage – High tempdb memory consumption may indicate heavy temporary object usage or insufficient indexing.
• Investigate Memory Clerks – Some clerks, such as MEMORYCLERK_SQLTRACE, may indicate excessive tracing that should be reviewed.
