If we currently have Tomcat 4 running on Win 2000, would there be significant overhead to run Apache as well just so that we can put up an error page when Tomcat has to be restarted?
Some of you mentioned I should try using a type 4 driver, and I Googled around to brush up on different types, and I realize we probably use a type 1 driver since it's a JDBC to ODBC bridge. The database we're using is Raining Data's D3 database (a multivalue db), and I searched around and only found a couple of JDBC drivers that look like they might work, but they're type 3 drivers, and I'm wondering what (if any) additional layer I need to make a type 3 driver talk to the D3 database, or if I can simply drop it into my J2EE/Tomcat. These are the drivers I found: FusionWare, halfway down the page: http://www.sqlsummit.com/JDBCVend.htm Liberty JDBC: http://www.multivalue.com/LibJDBC.html ----- Original message ----- From: "David Smith" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[EMAIL PROTECTED]> Date: Mon, 14 Jun 2004 20:10:11 -0400 Subject: Re: how to show "System Unavailable" page when Tomcat is down To directly answer your question, essentially something has to be listening on port 80 even when Tomcat is down. The only way I know of to do that is to put up some kind of proxy server with a error page. I know Apache can be used that way, Squid looks like it could as well. On the other hand, you could also replace your ODBC driver with a genuine type 4 driver and make your site much more reliable. I think someone else already suggested that and I whole-heartedly agree. --David Stephen Huey wrote: > Though I'm capable of adding to the JSPs and servlets on an existing > site, I'm no web server guru, so I'm having a hard time with this > problem.
