Description

I have been able to build and run a cn VM with Ubuntu 9.10 64bit server following Dave’s instructions (excludes mercury). However, I noticed a lot of errors in the syslog file:

Feb 26 10:34:56 ubuntu jsvc.execr1231: Feb 26, 2010 10:34:56 AM java.util.prefs.FileSystemPreferences$2 run#893WARNING: Couldn't create user preferences directory. User preferences are unusable.#893Feb 26, 2010 10:34:56 AM java.util.prefs.FileSystemPreferences$2 run#893WARNING: java.io.IOException: No such file or directory

I went through and change groups and owner to tomcat6 (chown –R tomcat6.tomcat6 ) on several different directories:

/var/metacat
/var/lib/tomcat6
/usr/share/tomcat6

Doing that seems to have cleared the above errors.

These changes will need to be made to the deployment script

#1 Updated by Dave Vieglais over 12 years ago

I can verify that the "Couldn't get file lock" messages are appearing in my log:

Feb 4, 2010 10:26:02 PM java.util.prefs.FileSystemPreferences syncWorld
WARNING: Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock.

but the application (/knb) operates as expected. The other warnings did not appear in my logs. Permissions on the folders mentioned on my system:
