14 Managing Security
14-6 Administration Guide
Use the Manage Caching Realm button to clear the user, group, and ACL caches.
Caution: If the
fileRealm.properties file becomes corrupted or is destroyed,
you must reconfigure the security information for WebLogic Server.
WebLogic Server cannot boot without a
fileRealm.properties file.
The
fileRealm.properties file contains default ACLs used to boot
WebLogic Server. Even if you write a custom security realm, you still need
a
fileRealm.properties file to boot WebLogic Server since the custom
security realm is not initially called during the start-up sequence.
Therefore, BEA recommends that you take the following steps:
Make a backup copy of the
fileRealm.properties file and put it in a
secure place.
Set the permissions on the
fileRealm.properties file such that the
administrator of the WebLogic Server deployment has write and read
privileges and no other users have any privileges.
