• What is the cause and solution for SAP error message DB6PM749 - DBCFG - SOFTMAX: value &1 not permitted or larger LOGPRIMARY * 100 ?

  The SAP error message *DB6PM749 DBCFG - SOFTMAX: value &1 not permitted or larger LOGPRIMARY  100* typically relates to the configuration of the database, specifically concerning the settings for the transaction log space in a DB2 database environment. This error indicates that the value set for the SOFTMAX parameter exceeds the permissible limit, which is defined as `LOGPRIMARY  100`.
  Cause:
  
  
  SOFTMAX Parameter: The SOFTMAX parameter in DB2 defines the maximum amount of log space that can be allocated for a database. The error occurs when the value assigned to SOFTMAX is either:
  
  Greater than LOGPRIMARY * 100, or
  An invalid value that does not meet the database's configuration requirements.
  
  
  
  LOGPRIMARY Parameter: The LOGPRIMARY parameter specifies the number of primary log files allocated for the database. The SOFTMAX value is expected to be within a certain range based on this parameter.
  
  
  Solution:
  To resolve this error, you need to adjust the SOFTMAX value to ensure it is within the allowed limits. Here are the steps to do this:
  
  
  Check Current Settings:
  
  Use the DB2 command line or a database management tool to check the current values of LOGPRIMARY and SOFTMAX.
  db2 get db cfg for <database_name>
  
  
  
  
  Calculate the Maximum Allowed SOFTMAX:
  
  Calculate the maximum allowed value for SOFTMAX using the formula:
  Maximum SOFTMAX = LOGPRIMARY * 100
  
  
  
  
  Update SOFTMAX:
  
  If the current SOFTMAX value exceeds the calculated maximum, you need to update it to a permissible value. You can do this using the following command:
  db2 update db cfg for <database_name> using SOFTMAX <new_value>
  
  Ensure that <new_value> is less than or equal to LOGPRIMARY * 100.
  
  
  
  Restart the Database (if necessary):
  
  In some cases, you may need to restart the database for the changes to take effect.
