Unix error warning: could not create system preferences directory. system preferences are unusable. code 2. Cause The non-root ID that is being used to start WebSphere Application Server does not have a user_home directory. Therefore this non-root ID is unable to access the root user's "/etc/.java/.systemPrefs". This produces the aforementioned warning messages every 30 seconds in the profile_root/logs/server_name/systemout.log. The root ID used to start Websphere Application Server can not find the Java system pref checklockfile0errorcode file. Diagnosing the problem For non-root, you can confirm this issue by trying to start WebSphere using the "root" ID. Review the Websphere_Home/profiles/

Could not lock System prefs. Unix error code Technote (troubleshooting) /etc/.java/.systemprefs/com create failed Problem The following error is written to the Lotus Domino server console: "Java.util.prefs.FileSystemPreferences checkLockFile0ErrorCode WARNING:
Could Not Lock System Prefs. Unix Error Code 6
Could not lock System prefs. Unix error code" Resolving the problem The following is a release note that details an issue with Java errors within http://www-01.ibm.com/support/docview.wss?uid=swg21515420 Domino on UNIX (AIX, z/OS, Solaris): This error occurs because the JRE looks for security settings in /etc/.java and $HOME/.java by default. However, Domino installs its own JRE within the Notes Executable directory (/opt/lotus/notes/latest/PLAT/jvm), and installs System Preferences files there. On some UNIX platforms if a JDK/JRE is installed locally for http://www-01.ibm.com/support/docview.wss?uid=swg21249277 the Operating System, then this install may create a /etc/.java directory which is owned/writeable by root. Since Domino does not run as root, it is unable to lock the preferences file in this directory hierarchy, resulting in the above error message. Additionally, the deinstallation of a JDK/JRE on a UNIX platform may leave behind this directory structure, but with incomplete/missing files/hierarchy, causing the same or similar error. For example, it may leave behind /etc/.java/.systemPrefs without containing the files .system.lock and .systemRootModFile. Currently, there is no clear way to deal with this issue programmatically in Domino, due to the many ways Domino accesses Java functionality. It is recommended that you either: Remove /etc/.java and use local user preferences only, either in $HOME or just with what comes packaged with Domino (preferred) Recursively make /etc/.java globally readable/writeable/executable, but you will still be susceptible to the incomplete/missing files/hierarchy issue described above.

This "security module" fails to load unless an empty /etc/.java/.systemPrefs is created. Apparently, it is the preferences code within the Java runtime library that breaks if this directory does not exist. Creating this directory (nothing more than a simple "sudo mkdir -p /etc/.java/.systemPrefs") was enough to fix the problem. To prevent this hard-to-diagnose problem on an important use case, this empty directory should be created by default. Alternatively, the Java runtime library should be fixed to not depend on it to work correctly. Version-Release number of selected component
