| # cd /usr/local/zend/var/db # mv devbar.db devbar.db.bak # sqlite3 devbar.db sqlite> .read /usr/local/zend/share/devbar_sqlite_create_database.sql sqlite> .read /usr/local/zend/share/devbar_fixtures.sql sqlite> .quit # chmod 664 devbar.db # chown zend:apache devbar.db # /usr/local/zend/bin/zendctl.sh restart |
Under certain conditions, the sqlite database used by Z-Ray is not generated correctly. The database must be generated manually.
