How To Fix RSRCACHE022 - Cluster table for large data

SAP Error Message - Details

• Message type: E = Error

• Message class: RSRCACHE - Messages for OLAP Cache

• Message number: 022

• Message text: Cluster table for large data

What causes this issue?

If this option is selected, cache entries with query data that exceed
the predefined size limit when initially created are written to the
cluster table (also known as index table). It is not beneficial to use
cluster tables when transporting larger data volumes between the
database and application server because this requires multiple implicit
SELECTS. However, it is possible to save in internal tables; this means
that the data export can take place in an internal table instead of an
XSTRING, which offers better performance under some circumstances.

• What is the cause and solution for SAP error message RSRCACHE022 - Cluster table for large data ?

  The SAP error message RSRCACHE022 typically indicates an issue related to the resource cache for cluster tables when dealing with large datasets. This error can occur in various scenarios, particularly when the system is trying to read or process large amounts of data from cluster tables, which can lead to performance issues or memory constraints.
  Cause:
  
  Large Data Volume: The error often arises when the system attempts to process a large volume of data from cluster tables, which can exceed the memory limits or cache size.
  Insufficient Memory: The SAP system may not have enough memory allocated to handle the data being processed, leading to cache overflow.
  Configuration Issues: Incorrect configuration settings for the resource cache or the database can also contribute to this error.
  Database Performance: Slow database performance or locks on the database can exacerbate the issue, leading to timeouts or failures in data retrieval.
  
  Solution:
  
  Increase Memory Allocation: Review and increase the memory allocation for the SAP system, particularly for the buffer and cache settings. This can be done in the SAP profile parameters (e.g., abap/heap_area_total, abap/heap_area_dia, etc.).
  Optimize Queries: If possible, optimize the queries that are being executed against the cluster tables to reduce the amount of data being processed at one time.
  Adjust Cache Settings: Check and adjust the settings for the resource cache in the SAP system. This may involve increasing the size of the cache or modifying how data is cached.
  Database Tuning: Ensure that the database is properly tuned for performance. This may include indexing, optimizing queries, and ensuring that there are no locks or long-running transactions that could be affecting performance.
  Batch Processing: If applicable, consider processing data in smaller batches rather than attempting to process large datasets all at once.
  SAP Notes: Check for any relevant SAP Notes or updates that may address this specific error or provide additional guidance on handling large data volumes.
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for guidance on memory management and performance tuning.
  Transaction Codes: Use transaction codes like ST02 (Tune Summary), ST04 (Database Performance), and ST22 (Dump Analysis) to analyze performance issues and memory usage.
  Monitoring Tools: Utilize SAP monitoring tools to keep track of system performance and identify bottlenecks.
  SAP Community: Engage with the SAP Community or forums for insights from other users who may have encountered similar issues.
