Thanks Don,

If the servers need reboot while live, we can also disable half of the cluster through mod_jk without loosing session or outage. The algorithm will look like this:

a) On halprdjbs01 and halprdjbs02

-Disable halprdjbs01 and halprdjbs02 in halprdweb01 through jkstatus -Disable halprdjbs01 and halprdjbs02 in halprdweb02 through jkstatus -Wait for existing sessions to expire in haljbs01 and haljbs02 (sessions draining, can take several hours depending on usage) -Reboot halprdjbs01 and halprdjbs02 -Re enable halprdjbs01 and halprdjbs02 in halprdweb01 through jkstatus -Re enable halprdjbs01 and halprdjbs02 in halprdweb02 through jkstatus

b) Same on halprdjbs03 and halprdjbs04

-Disable halprdjbs03 and halprdjbs04 in halprdweb01 through jkstatus -Disable halprdjbs03 and halprdjbs04 in halprdweb02 through jkstatus -Wait for existing sessions to expire in halprdjbs03 and haljbs04 (sessions draining) -Reboot halprdjbs03 and halprdjbs04 -Re enable halprdjbs03 and halprdjbs04 in halprdweb01 through jkstatus -Re enable halprdjbs03 and halprdjbs04 in halprdweb02 through jkstatus

I have restarted ezAir test.
When requesting to restart this application can you refer to it as ezatst on haltstapp03. That way we won't get it confused with webtst which are different apps.

Thanks-

Mike
