• What is the cause and solution for SAP error message SDBALM074 - Usage of the data cache with OMS rollback data in % ?

  The SAP error message SDBALM074 indicates that there is an issue with the data cache in the context of the Online Transaction Processing (OLTP) system, specifically related to the Object Management System (OMS) rollback data. This error typically arises when the data cache is being used in a way that is not optimal, leading to potential performance issues or inconsistencies in the data.
  Cause:
  
  Data Cache Overload: The data cache may be overloaded with rollback data, which can occur if there are many transactions being processed simultaneously or if there are long-running transactions that are not being committed or rolled back in a timely manner.
  Configuration Issues: Incorrect configuration settings for the data cache or OMS can lead to inefficient handling of rollback data.
  System Performance: High system load or performance issues can exacerbate the problem, leading to increased usage of rollback data in the cache.
  Database Locking: If there are locks on database tables, it can prevent transactions from being completed, leading to an accumulation of rollback data.
  
  Solution:
  
  Monitor and Analyze: Use transaction codes like ST02 (Tune Summary) and ST04 (Database Performance) to monitor the data cache and identify any performance bottlenecks.
  Adjust Cache Settings: Review and adjust the settings for the data cache and OMS in the SAP system configuration. This may involve increasing the size of the data cache or optimizing the parameters related to rollback data handling.
  Transaction Management: Ensure that transactions are being committed or rolled back in a timely manner. Long-running transactions should be reviewed and optimized to minimize their impact on the data cache.
  System Performance Tuning: Consider tuning the overall system performance by optimizing database queries, increasing hardware resources, or adjusting system parameters to better handle the workload.
  Regular Maintenance: Perform regular maintenance tasks such as database reorganization and updates to ensure that the system is running efficiently.
