No matter which version of
Oracle's Application Server you are using, you will have to manage log
files. Just about every component in Oracle Application Server 10g
creates a log file. These files can, and will, quickly fill up your
hard drive if you do not manage them.
Run Only the
Components in Production that you are Using.
This seems obvious
but I find that a lot of companies are running components (like
Wireless) that they are not using. If you are not using it, don't start
it (or shut it down after restarting) to free up the server resources
the component is using. This will also reduce the components creating
Log Files Frequently
Create a script that
will archive (and possible compress) the log files you need to
maintain. The script could also read through a log file looking for
errors and delete the file if it finds no errors. Also use OEM to set
the appropriate logging levels. If you Application Server is running
consistently without problems, consider reducing the logging level for
certain components. Logging unnecessary data is simply a waste of
all these Log Files?
Each component has a
subdirectory under the instance's $ORACLE_HOME. Each of these
subdirectories has a /log subdirectory where that component writes it's
log files. OC4J containers each have a subdirectory located under the:
Each application deployed in a container will be in a subdirectory of
that container with a /log directory of its own.
The Web Cache may be on a seperate server, either way it writes it's
log data to: $ORACLE_HOME/webcache/log
Of course OHS always creates large logs and AS10g automatically
rotates the logs for you. Now you do not have to manually restart OHS
to change logs files.
Don't Forget the Database.
Finally, you must manage the ARCHIVELOG files from the asdb database.
(You are running in ARCHIVELOG mode!?!?!). These file need to be
maintained for as long as you are maintaining asdb backups. Remember, a
backup can not be rolled forward without the ARCHIVELOG files.
