How To Fix DB6613 - Maximum fill level of the database heap

SAP Error Message - Details

• Message type: E = Error

• Message class: DB6 - DB6: Alert Monitoring and Alert Configuration

• Message number: 613

• Message text: Maximum fill level of the database heap

What causes this issue?

The database heap is a global area the database uses for memory areas
it administers itself, such as the:
Log buffer
Catalog cache
Control structures for the buffer pool

System Response

If the database heap is full, transactions may terminate.

How to fix this error?

If there is an error, increase the size of the database heap using:
<LB>UPDATE DB CFG USING DBHEAP <value></>
Increasing this value increases the use of virtual memory, which
increases paging if there is not enough main memory available.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message DB6613 - Maximum fill level of the database heap ?

  The SAP error message DB6613, which indicates "Maximum fill level of the database heap," typically arises when the database heap memory allocated for the SAP system has reached its maximum limit. This can lead to performance issues or even system downtime if not addressed promptly.
  Cause:
  
  Memory Allocation Limits: The database heap is a memory area used by the database for various operations. If the configured maximum fill level is reached, it can prevent further allocations.
  High Load: A sudden increase in database load due to heavy transactions or queries can lead to rapid consumption of heap memory.
  Memory Leaks: Inefficient queries or poorly optimized database operations can lead to memory not being released properly, causing the heap to fill up.
  Configuration Issues: Incorrect database configuration settings may lead to insufficient memory allocation for the heap.
  
  Solution:
  
  
  Increase Heap Size: 
  
  Adjust the database configuration to increase the maximum fill level of the database heap. This can usually be done through the database management tools or configuration files.
  For example, in an SAP HANA database, you can adjust the max_memory parameter.
  
  
  
  Optimize Queries: 
  
  Review and optimize SQL queries to ensure they are efficient and do not consume excessive memory.
  Use indexes appropriately to speed up query execution and reduce memory usage.
  
  
  
  Monitor Database Performance: 
  
  Use monitoring tools to keep an eye on database performance and memory usage. This can help identify trends and potential issues before they become critical.
  SAP provides tools like SAP Solution Manager for monitoring.
  
  
  
  Database Maintenance: 
  
  Regularly perform database maintenance tasks such as cleaning up old data, archiving, and reorganizing tables to free up memory.
  Ensure that statistics are up to date to help the database optimizer make better decisions.
  
  
  
  Check for Memory Leaks: 
  
  Investigate and resolve any potential memory leaks in the application or database layer that could be causing excessive memory consumption.
  
  
  
  Consult Documentation: 
  
  Refer to the specific database documentation (e.g., Oracle, HANA, SQL Server) for detailed instructions on configuring memory settings.
