Symptoms

After updating third party products to the latest version, Apache will not load with the following errors:

• httpd: Syntax error on line 16 of /exlibris/primo/p4_1/primoe/apache/conf/httpd.conf:
• Cannot load /exlibris/primo/p4_1/product/local/apache/modules/mod_jk.so into server: /exlibris/primo/p4_1/product/local/apache/modules/mod_jk.so: cannot open shared object file: No such file or directory

Workaround

The apache will not load since the mod-jk module has been omitted from the latest version of apache. This will be fixed for future releases.

In the meantime please use the following workaround:

1. log into the relevant server via ssh.

2. Run the following:

ls -d  /exlibris/product/http*

This will list all the apache versions that reside on the server.

3. If an older version of apache exists, copy over the mod-jk module from the latest version prior to the current one. i.e.:

cp -p /exlibris/product/httpd-2.2.15/modules/mod_jk.so /exlibris/product/httpd-2.2.31/modules/

If only only the latest version of apache shows up please download the <<attached file>> and place it in

/exlibris/product/httpd-2.2.31/modules/

4. Restart apache.
