How To Fix RT560 - &1 &3 > &2 &3 (15 Min.) SAP buffer directory usage exceeds threshold

SAP Error Message - Details

• Message type: E = Error

• Message class: RT - Monitoring infrastructure MSG and alert texts

• Message number: 560

• Message text: &1 &3 > &2 &3 (15 Min.) SAP buffer directory usage exceeds threshold

What causes this issue?

The percentage utilization of the directory for a SAP buffer has
exceeded the threshold value. If the directory has filled up, the
system cannot place any more data in the buffer (even if this would
still be possible based on the size of the relevant buffer).

How to fix this error?

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 RT560 - &1 &3 > &2 &3 (15 Min.) SAP buffer directory usage exceeds threshold ?

  The SAP error message RT560 indicates that the usage of the SAP buffer directory has exceeded a predefined threshold. This can lead to performance issues and may affect the overall functioning of the SAP system. Here’s a breakdown of the cause, potential solutions, and related information for this error:
  Cause:
  
  
  Buffer Directory Usage: The error typically arises when the buffer directory usage exceeds the configured limits. This can happen due to:
  
  High volume of data being processed.
  Inefficient buffer management.
  Configuration settings that are not optimized for the current workload.
  Increased number of users or transactions that require more buffer space.
  
  
  
  Threshold Settings: The threshold for buffer usage is set in the system parameters. If the actual usage exceeds this threshold, the system raises this error.
  
  
  Solution:
  
  
  Monitor Buffer Usage: Use transaction codes like ST02 (Tune Summary) to monitor the buffer usage and identify the current status of the buffer directory.
  
  
  Adjust Buffer Parameters:
  
  Increase the buffer size if necessary. This can be done by adjusting the parameters in the instance profile (e.g., abap/buffersize).
  Review and adjust the parameters related to buffer management, such as abap/buffer/size and abap/buffer/threshold.
  
  
  
  Optimize Data Access:
  
  Analyze the data access patterns and optimize the way data is being accessed. This may involve tuning SQL queries or adjusting the way data is fetched from the database.
  Consider implementing caching strategies or optimizing the application logic to reduce the load on the buffer.
  
  
  
  Regular Maintenance:
  
  Perform regular maintenance tasks such as clearing the buffer or reorganizing the database to ensure optimal performance.
  Monitor the system regularly to ensure that buffer usage remains within acceptable limits.
  
  
  
  Consult SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or patches related to buffer management and performance tuning.
  
  
  Related Information:
  
  
  Transaction Codes: 
  
  ST02: To monitor buffer statistics.
  SM12: To check for lock entries that may be affecting performance.
  SM21: To view system logs for any related errors or warnings.
  
  
  
  SAP Documentation: Refer to the official SAP documentation for detailed information on buffer management and performance tuning.
  
  
  Performance Tuning: Consider engaging with SAP Basis consultants or performance tuning experts if the issue persists, as they can provide tailored solutions based on the specific system configuration and workload.
  
  
  By addressing the buffer usage and optimizing the system configuration, you can resolve the RT560 error and improve the overall performance of your SAP system.
