Is global memory shared across HA LTM's?

Hi Tarsier,

 

As far as I can tell Global variables aren't transfered over during failover. However, existing connections (if mirroring is turned on) will failover. I do believe that the irules would re-process the irules on the next connection. Of course this is all based on my observation

As Bhattman suggests, global memory isn't synched to the peer. I guess the benefit versus overhead doesn't justify it.

 

 

You can use 'info exists ::my_global_var' (Click here) to check if a variable exists before trying to use it. But it would probably make sense to just reset the connection if a required global variable doesn't exist (which is what should happen when you get a runtime TCL error trying to access a variable that isn't set).

Thank you for the feedback. Unfortunately, that is the answer I expected.

Sorry to disappoint ;-)
