What causes this issue?

A Deadlock is a mutual lock of two or more running transactions. It
means that they are both in a wait state and each is waiting for the
other.
Example:
T1 holds lock A and requires lock B.
T2 holds lock B and requires lock A.
The system resolves this wait situation by resetting one of the
transactions after a certain wait time has expired. The parameter
DLCHKTIME determines this wait time.

System Response

The bigger the value set for the parameter, the longer the deadlock
situations continue and block system operation. Conversely, you should
not set too low a value for the parameter, as identifying deadlocks in
the system can affect performance.

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 DB6543 - The DLCHKTIME parameter value is low enough ?

  The SAP error message DB6543, which states "The DLCHKTIME parameter value is low enough," typically relates to database performance and configuration settings. This error is associated with the database's deadlock check time, which is a parameter that determines how often the database checks for deadlocks.
  Cause:
  The error occurs when the DLCHKTIME parameter is set to a value that is considered too low. This can lead to performance issues because the database is checking for deadlocks too frequently, which can consume resources and impact overall system performance.
  Solution:
  To resolve this issue, you can increase the value of the DLCHKTIME parameter. Here are the steps to do this:
  
  
  Access the Database Configuration:
  
  Depending on your database system (e.g., Oracle, SQL Server, etc.), you will need to access the database configuration settings. This may involve using a database management tool or command line.
  
  
  
  Modify the DLCHKTIME Parameter:
  
  Locate the DLCHKTIME parameter in the configuration settings.
  Increase its value to a more appropriate level. The exact value will depend on your specific system and workload, but it is generally recommended to set it to a higher value than the current setting.
  
  
  
  Restart the Database:
  
  After making changes to the configuration, you may need to restart the database for the changes to take effect.
  
  
  
  Monitor Performance:
  
  After adjusting the parameter, monitor the database performance to ensure that the changes have resolved the issue and that there are no new performance problems.
  
  
  
  Related Information:
  
  Documentation: Refer to the official documentation for your specific database system to understand the implications of changing the DLCHKTIME parameter and to find recommended values.
  Performance Tuning: Consider reviewing other performance tuning parameters and settings in your database configuration to ensure optimal performance.
  SAP Notes: Check SAP Notes for any specific recommendations or patches related to this error message, as there may be updates or best practices provided by SAP.
  
  If you continue to experience issues after adjusting the DLCHKTIME parameter, it may be beneficial to consult with your database administrator or SAP support for further assistance.
