- SMT Mode (On, Off) ?The SAP error message RT857 related to SMT (Simultaneous Multithreading) mode typically indicates an issue with the configuration of the system's hardware or the settings in the SAP environment regarding the use of SMT. Here’s a breakdown of the cause, potential solutions, and related information:
Cause: SMT Configuration: The error may arise if the SMT mode is not properly configured on the server. SMT allows multiple threads to run on a single physical core, which can improve performance but may also lead to issues if not managed correctly. Hardware Limitations: The server hardware may not support SMT, or it may be disabled in the BIOS settings. SAP Kernel Version: The version of the SAP kernel being used may not be compatible with the current SMT settings. Operating System Settings: The operating system may have settings that conflict with the SMT configuration.
Solution: Check BIOS Settings: Ensure that SMT is enabled in the BIOS settings of the server.
