Use the max_dump_file_size parameter to limit the size of the trc File

Max_dump_file_size: this parameter can be used to limit the size of the trc file corresponding to a process (whether the process is an oracle background process or a serverprocess corresponding to the foreground application). Example: If a trc file already contains 4 GB, and keep increasing, then set max_dump_file_size1024m (note that this parameter has single quotation marks) and

Max_dump_file_size: this parameter can be used to limit the trc file size of a process (whether the process is an oracle background process or a server process corresponding to the foreground application: if a trc file has 4 GB and continues to grow, set max_dump_file_size = '1024m' (note that this parameter is enclosed in single quotes) and

Max_dump_file_size: this parameter can limit the trc file size of a process (whether the process is an oracle background process or a server process corresponding to the foreground application)
Use Case: If a trc file has 4 GB and continues to grow, set max_dump_file_size = '1024m'. (Note that this parameter value is enclosed in single quotes) then the trc file will no longer grow.
