    After Upgrade Express, OPAC gets: "503: Service Temporarily Unavailable"

    • Article Type: General
    • Product: Aleph
    • Product Version: 20

    We have completed all the steps in the Upgrade Express utility, however, the online catalog is now unavailable. We are getting the "503: Service Temporarily Unavailable" error message in the browser. Both apache and www_server are running, but they don't appear to be talking to one another.

    I've re-checked all the configuration files I could think of, and everything looks okay. Apache is running at port 4505 and www_server is running at 4500. There are no errors given in the apache or the www_server logs.

    Any suggestions on what to try to fix this?

    In the ./apache/conf/httpd.conf file, there's a setting:

    <IfModule mod_aleph_2.c>
    ServerPort 4991

    That's what tells apache where to connect to for the www_server. I had to change that to 4500, to match the setting in aleph_start. (I thought the Upgrade Express was supposed to copy the apache settings from the u19 tree, and evidently it didn't.)

    In another case, after a change had been made in aleph_start to change the ALEPH_SUB_PORT from "2" to "1", a corresponding change (from "4992" to "4991") needed to be made in httpd.conf.

    In any case, the catalog is running now.

    Note: KB 16384-10833 has a different cause of this same message.
