How To Fix DB6544 - Der DLCHKTIME parameter value is too high

SAP Error Message - Details

• Message type: E = Error

• Message class: DB6 - DB6: Alert Monitoring and Alert Configuration

• Message number: 544

• Message text: Der DLCHKTIME parameter value is too high

1st and 2nd blocks are copies of 1st and 2nd blocks of DB6 542

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.

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.

How to fix this error?

Reduce the value set for the parameter using the command:
<LB>UPDATE DB CFG USING DLCHKTIME <value></>

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 DB6544 - Der DLCHKTIME parameter value is too high ?

  The SAP error message DB6544 indicates that the value set for the DLCHKTIME parameter is too high. This parameter is related to the database connection settings in SAP systems, specifically concerning the time interval for checking the database connection.
  Cause:
  The DLCHKTIME parameter defines the time interval (in seconds) for the database connection check. If this value is set too high, it can lead to performance issues or delays in detecting connection problems. The system expects a reasonable value to ensure timely checks without overloading the system with frequent checks.
  Solution:
  To resolve the error, you need to adjust the DLCHKTIME parameter to a more appropriate value. Here are the steps to do this:
  
  
  Access the SAP System:
  
  Log in to your SAP system.
  
  
  
  Navigate to the Profile Parameters:
  
  Use transaction code RZ10 to access the profile parameters.
  
  
  
  Select the Profile:
  
  Choose the appropriate instance profile where the DLCHKTIME parameter is set.
  
  
  
  Edit the Parameter:
  
  Look for the DLCHKTIME parameter in the list. If it is set to a high value (e.g., greater than 60 seconds), consider reducing it to a more standard value (e.g., 10-30 seconds).
  
  
  
  Save Changes:
  
  After making the changes, save the profile.
  
  
  
  Restart the Instance:
  
  For the changes to take effect, you may need to restart the SAP instance.
  
  
  
  Related Information:
  
  Default Values: The default value for DLCHKTIME is typically set to a lower value (e.g., 10 seconds). It is advisable to keep it within a reasonable range to ensure efficient connection management.
  Performance Monitoring: After adjusting the parameter, monitor the system performance and connection stability to ensure that the changes have had the desired effect.
  Documentation: Refer to the SAP documentation or the specific database documentation for more details on connection parameters and best practices.
  
  If the issue persists after adjusting the parameter, further investigation may be required, including checking for network issues, database performance, or other related configurations.
