What causes this issue?

This value is the maximum fill level (in percent) of the secondary log
area since the system was started or since the last monitor reset.

System Response

The more secondary log area that needs to be added, the worse
performance is. If the secondary log area is full, it means
transactions are terminating due to insufficient log area. As it is
these transactions that have logged a large number of changes,
resetting them can be expensive.

How to fix this error?

If an error occurs, you can extend the log area by increasing the
maximum number of log files:
<LB>UPDATE DB CFG USING LOGPRIMARY <value></> (primary log files)
<LB>UPDATE DB CFG USING LOGSECOND <value>,,</> (secondary log
files)
You can also extend the log area by increasing the size of individual
files:
<LB>UPDATE DB CFG USING LOGFILSIZ <value>,,</> (parameter
LOGFILSIZ)

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message DB6600 - The secondary log file is full ?

  The SAP error message DB6600, which indicates that "The secondary log file is full," typically arises in the context of database management within an SAP system. This error is related to the database's transaction log, which is crucial for maintaining data integrity and supporting rollback operations.
  Cause:
  
  
  Full Secondary Log File: The primary cause of this error is that the secondary log file, which is used to store transaction logs, has reached its maximum capacity. This can happen if:
  
  There are a large number of transactions being processed.
  The log file is not being cleared or backed up regularly.
  The database is not configured to handle the volume of transactions effectively.
  
  
  
  Database Configuration: Inadequate configuration of the database parameters related to log file size and management can also lead to this issue.
  
  
  Long-Running Transactions: If there are long-running transactions that hold onto log space, they can prevent the log from being cleared.
  
  
  Solution:
  
  
  Backup the Log Files: If your database supports it, perform a backup of the transaction logs. This will free up space in the secondary log file.
  
  
  Increase Log File Size: If the log file is consistently filling up, consider increasing the size of the secondary log file or adding additional log files to accommodate the transaction volume.
  
  
  Check for Long-Running Transactions: Identify and resolve any long-running transactions that may be holding onto log space. You can use transaction monitoring tools or SQL queries to find these transactions.
  
  
  Database Configuration: Review and adjust the database configuration settings related to log file management. This may include parameters for log file size, number of log files, and log retention policies.
  
  
  Regular Maintenance: Implement regular maintenance tasks such as log backups and clearing old logs to prevent the log files from filling up in the future.
  
  
  Consult Database Documentation: Depending on the database system (e.g., Oracle, SQL Server, HANA), refer to the specific documentation for guidance on managing transaction logs.
  
  
  Related Information:
  
  Database Type: The specific steps to resolve the issue may vary depending on the underlying database system (e.g., Oracle, SQL Server, SAP HANA).
