You can do it, but you do kind of have to have your attention on the screen. I have an ssh client on my smartphone for this purpose, but it's of limited use because sudo requires a password I do *not* have. You can also tether your laptop to your phone and do just about anything . > httpd was working fine.

I don't think of anything specific that does this kind of thing, but it does sound a little dangerous and also a little fragile. Do you have just a single Tomcat instance? Perhaps a better use of your time would be to re-work your environment so that you have some redundancy at the Tomcat level. You don't even need any additional hosts if you have enough resources (e.g. memory). Just split your Tomcat installation into CATALINA_HOME and a pair of CATALINA_BASE structures and run the applications concurrently, side-by-side. You will need distinct port numbers for each instance. Configure the reverse proxy to load-balance between the two instances. It's up to you to decide if you want to set up clustering and that other stuff. But simple sticky-sessions (the default) should get you a lot of mileage. - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl3pffkACgkQHPApP6U8 pFgy/g/+PmyIPgrrL8u/sWUOoJX11iBPj4w0M83SQxwpqUo6n7LJRVy3K1d5CW+l eCxRHZOKEjIW7utsZCR7FpXY/xeuimQiuPhBz5KvVxO7egVWTNGSRt63jwD2IivW klGZAzVWbLYsvvKLYwOeYJ4iUF99YFv60Mz+i2v0Unc1WWxUbxSo4fS7KFVM++8r RllSDiOsL59gzeGani75TqGE0fr+D3Lk83abf7hCCxicX8VilwoOlkJZS7pAujOd e9GKpW92tDIddLfjla/IqeNJDmHz8SBHmiy1fXNzasvP9tBFLCRXM+Lh2TF4Es7q 1piD7aBYFjcsct94e77usy+1rv+gAie5TJK23m1o76ehzQa3hqvbUldEj+SFjR/f D6ebd6BD8jsxAulN2Jl+C4dBbBey/exKmmg0xSiX0D5a5sFV9xUsOqGcJRlR/W1e gYWW1E6SeOzPbqO63npDxldzA5XlOHDfU3x4qnuoiGFfh5gRzqczCi5Snxc+VLRF NxE59Acfwk59yb8m9BJGiXKjVNzgPvPHd4YE0FFc1k0EmiSsEEkNpeiWy4zONg4q Or8QVJGuQJK41GBDoT7wqipU/hhM+vQqICcYRg3pXpmZtQ3HtXX+TeDFUw3tmlYy ANkzomPk+meCvaj6WixXSH0vLBTk4b/09JBF8Bwt+CAeSpsn8rg= =WSs4 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
