Does iControl have cache

Hi Robbie

The information you get is taken from the memory. I've never gotten cached information on the iControl calls. Even the changes you make are stored in memory and has to be written to disk with another iControl call.

/Patrik

The iControl server side code was implemented to only update the running configuration in memory. Unlike the GUI, which does a disk flush each operation, we found that the overhead of doing that for large configurations was too long and effected API based applications negatively. The best practice is to make the various changes you want and then issue a System.ConfigSync.save_configuration() method to flush it to disk.

hmm,this api call is to get pool status

Develpoer found that in 1th second,pool A status is green then we shutdown pool A,the issue an iControl call,but pool A status is still green.....

Did you shut down the pool member with the help of a failed monitor, or did you disable it? A pool member can be available (green) while disabled.

/Patrik

it is in our prod env

we use icontrol to get status of pools and display them in webpage

yesterday when I use monitor to make pool A down,however,I refresh the webpage,pool A is still green(refresh webpage will make a new api call to get pool status from F5 LTM)

how to contact Joe?
