Error Log
The server sends diagnostic information and records error messages to a log file
located, by default, in:
■
UNIX: ORACLE_HOME/Apache/Apache/logs/error_log
■
Windows: ORACLE_HOME\Apache\Apache\logs\error_log
The file name can be set using the
directive.
PID File
When the server is started, it notes the process ID of the parent httpd process to the
PID file located by, default, in
■
UNIX: ORACLE_HOME/Apache/Apache/logs/httpd.pid
■
Windows: ORACLE_HOME\Apache\Apache\logs\httpd.pid
This filename can be changed with the
directive. The process ID is for use
by the administrator for restarting and terminating the daemon. If the process dies
(or is killed) abnormally, then it is necessary to kill the children httpd processes.
Piped Log
Oracle HTTP Server is capable of writing error and access log files through a pipe to
another process, rather than directly to file. This increases the flexibility of logging,
without adding code to the main server. In order to write logs to a pipe, replace the
file name with the pipe character “|”, followed by the name of the executable which
should accept log entries on its standard input. Oracle HTTP Server starts the
piped-log process when the server starts, and restarts it if it crashes while the server
is running.
