Each time it starts, SAP ASE writes start-up information to a local error log file. The installation program automatically sets the error log location when you configure a new SAP ASE.
Many error messages from SAP ASE are written only to the user’s terminal. However, fatal error messages (severity levels 19 and above), kernel error messages, and informational messages from SAP ASE are recorded in the error log file.
SAP ASE keeps the error log file open until you stop the server process. Before deleting old messages to reduce the size of the error log, stop the SAP ASE process.
See the Configuration Guide for your platform to view the default location and file name of the error log for your platform.
