解説：
Reference:
https://gerardnico.com/db/oracle/trace_file
https://docs.oracle.com/html/E25494_01/monitoring001.htm
Each server and background process can write to an associated trace file. When an internal error is detected by a process, it dumps information about the error to its trace file. Some of the information written to a trace file is intended for the database administrator, and other information is for Oracle Support Services. Trace file information is also used to tune applications and instances.
