LB::reselect problem

Thanks for the reply, and for those problems. I verified that no 500/503 errors are being put up with livehttpdheaders (I was also checking the apache log).

 

I changed it a bit, and now am checking LTM logs:

 

Apr 21 16:16:30 tmm tmm[1564]: 01220001:3: TCL error: redirect_on_bad_status - can't read "failure": no such variable while executing "if { $failure == 1 } { LB::detach LB::mode rr LB::reselect pool [LB::server pool] set failure 0 }"

 

Is this not a "global" variable?

 

I thought it would make sense to just nest the when LB_SELECTED { inside of the when HTTP_RESPONSE { , but that did not seem to work - it wouldn't let me save the iRule that way - command is not valid in the current scope.

 

Here is what I changed it to:

 

 

when HTTP_RESPONSE {

 

if { [HTTP::status] == 503 }{

 

set ::failure 1

 

}

 

}

 

 

when LB_SELECTED {

 

if { $::failure == 1 } {

 

LB::detach

 

LB::mode rr

 

LB::reselect pool [LB::server pool]

 

set ::failure 0

 

}

 

}

 

 

 

I am testing out Tomcat session replication, and I want to make it so that when we have a Tomcat server that is restarting (503 error) the customer doesn't see any errors and just gets tossed onto another server with no loss of data.

 

BTW I have seen variables set as ::variable (assuming that is global), tried that as well and it didn't work...
