    Description:
    I have started to use the Alert functionality in MetaLib and discovered that a number of resources either give the 'Z39.50 gate not running.' or the 'The database is not available.' message, while a regular search into the same resources doesn't cause a problem. What could the cause of this be?

    Resolution:
    The order of your cronjob is as follows:

    # METALIB CLEAN-UP
    # Run (compact) backup every day at 2.00 am:
    # Run clean_apache_logs script once a week (every monday at 3.00 am):
    # Run util_k_01.cron every day at 3.30 am with 5 searches running in parallel

    The Z39 servers are launched by the first z39 query made by a user in the User Interface.
    After the metalib shutdown in your cron job, the z39 server is shut down and it will not start until the first user launches a search in the user interface.

    Solution: We suggest that you change the order of the cronjobs as follow, providing ample time for each job:

    # RUN ALERTS
    # METALIB CLEAN-UP
    # METALIB BACKUP
    # CLEAN APACHE LOGS

    cron jobs,util k, alerts
