Slow Ramp + priority Group Activation

if pool contians 2 pool members , if slowe ramp is enabled on one pool member it will receive less number of connections than it should ( when marked up aftre being down ) for amount of time depending on slow ramp value .

 

Q1 : if 2 pool members are active / backup ( one has priority group = 10 & the other has priority group = 20 ) ., if slow Ramp is enabled on master one , will it behave the same like mentioned above when going down then up again ?

 

Q2 : if 2 pool members are active / backup ( one has priority group = 10 & the other has priority group = 20 ) , if no Slow Ramp is enabled , and the master went down for some time , when it comes up will the connections on the backup be moved to it or it will be dropped , or the old connections will continue on backup while new on master ?

    if pool contians 2 pool members , if slowe ramp is enabled on one pool member how can you enable slow ramp on only one pool member?? i thought slow ramp is pool level setting.

    Thanks , you are right .

     

    what about if : priority group activation is enabled , master server( master pool member ) is coming up after going down , will new connections only go to it or even existing connections will be dropped from current server & will be sent to it ?
