Stability and Performance - Oracle WebLogic Server 12c Advanced Administration - page 208

In most cases, the performance should suffice if the environment is very stable, with
predictable behavior and common bottlenecks removed.
Limiting the log disk usage
WebLogic Server 12 c fixes a file size limit of 5 MB for the domain, server, and HTTP logs.
It also sets 100 as the maximum number of rotated files for the domain and server logs.
The HTTP access.log file does not have a default limit of rotated files. This is the default
configuration for WebLogic Server 12 c domains running in the production mode.
In this recipe, the logging subsystem will be configured, so that all the PROD_DOMAIN domain
logfiles usage never surpasses a known disk size usage.
Getting ready
The logging subsystem is configured by using the Administration Console, so make sure the
Administration Server is running.
