• What is the cause and solution for SAP error message DB6PM746 - DBCFG: the sum of LOGPRIMARY and LOGSECOND must not be larger than &1 ?

  The SAP error message DB6PM746 DBCFG: the sum of LOGPRIMARY and LOGSECOND must not be larger than &1 typically occurs in the context of database configuration, particularly when setting up or modifying the database parameters for a SAP system. This error is related to the configuration of the database's log files.
  Cause:
  The error indicates that the combined size of the primary log files (LOGPRIMARY) and secondary log files (LOGSECOND) exceeds the maximum limit set by the database configuration. Each database has a maximum limit for the total number of log files that can be allocated, and if the sum of the primary and secondary log files exceeds this limit, the error is triggered.
  Solution:
  To resolve this error, you need to adjust the values of LOGPRIMARY and LOGSECOND so that their sum does not exceed the specified limit (&1). Here are the steps to do this:
  
  
  Check Current Configuration:
  
  Use the database management tools or SQL commands to check the current values of LOGPRIMARY and LOGSECOND.
  Determine the maximum allowed value for the sum of these parameters, which is indicated by &1 in the error message.
  
  
  
  Adjust Parameters:
  
  Reduce the values of LOGPRIMARY and/or LOGSECOND so that their sum is less than or equal to the maximum limit.
  For example, if LOGPRIMARY is set to 10 and LOGSECOND is set to 5, their sum is 15. If the maximum allowed is 12, you could change LOGPRIMARY to 8 and LOGSECOND to 4.
  
  
  
  Apply Changes:
  
  After making the necessary adjustments, apply the changes. This may involve restarting the database or the SAP system, depending on the database and the changes made.
  
  
  
  Verify:
  
  After applying the changes, verify that the error no longer occurs and that the database is functioning correctly.
