• What is the cause and solution for SAP error message DB02073 - &1 < &2 redo entries per redo log space requests ?

  The SAP error message DB02073 indicates that there is an issue with the redo log space in the database. This error typically occurs when the database is unable to allocate enough space for redo log entries, which are crucial for maintaining data integrity and supporting recovery processes.
  Cause:
  The error message DB02073 &1 < &2 redo entries per redo log space requests suggests that the number of redo entries requested exceeds the available redo log space. This can happen due to several reasons:
  
  
  Insufficient Redo Log Space: The database may not have enough redo log files or the existing files may be too small to accommodate the volume of transactions being processed.
  
  
  High Transaction Volume: A sudden spike in transaction volume can lead to a situation where the redo log space is quickly consumed.
  
  
  Long-Running Transactions: Transactions that take a long time to complete can hold onto redo log space longer than necessary, leading to exhaustion of available space.
  
  
  Configuration Issues: Incorrect configuration of the database parameters related to redo log management can also lead to this error.
  
  
  Solution:
  To resolve the DB02073 error, consider the following steps:
  
  
  Increase Redo Log Space:
  
  Add more redo log files to the database.
  Increase the size of existing redo log files if possible.
  
  
  
  Monitor and Optimize Transactions:
  
  Review long-running transactions and optimize them to reduce their duration.
  Ensure that transactions are committed as soon as possible to free up redo log space.
  
  
  
  Database Configuration:
  
  Check the database configuration settings related to redo log management. Ensure that they are set appropriately for your workload.
  Consult the database documentation for recommended settings based on your environment.
  
  
  
  Regular Maintenance:
  
  Implement regular maintenance tasks to monitor and manage redo log space usage.
  Consider archiving or purging old logs if applicable.
  
  
  
  Database Performance Tuning:
  
  Analyze the overall performance of the database and identify any bottlenecks that may be contributing to the issue.
  Use performance monitoring tools to track redo log usage and identify trends.
