There are three property files which control the behavior of the ffdc filter. The files which are used are based upon the state of the server:
- ffdcStart.properties: used during start of the server
- ffdcRun.properties: used after the server is ready
- ffdcStop.properties: used while the server is in the process of stopping
The only file that you should modify is the ffdcRun.properties file. You can change the value of
ExceptionFileMaximumAgeproperty. This property specifies the number of days that an FFDC log remains in the <profileroot>/logs/ffdc directory before being deleted. As part of your diagnostic data collection plan, you might want to modify the
ExceptionFileMaximumAgeproperty to ensure that the FFDC files remain on your system for a certain time period. You should not modify any other properties unless you are asked to do so by the support team.
