Avoid Breakup... By Any Means : CheckPoint : Check Firewalls in Sync

Every "TRUE" Relation needs syncronisation..

Most of the relations are breaking up just because of lack of Communication, May be a Sync Problem..

The same problem which we face/faced in normal life can happen in a clustered environment, will lead into misbehaviour in cluster node... So before the "BreakUP" happens try the following in case of checkpoint... However am not good to give a similar solution in real LIFE...

How can I check that my Checkpoint Cluster is in Sync ?

In order to ensure that the State Tables of all your nodes within your Checkpoint Cluster are syncronised you will need to check the #VALS of your State Table summary on each node.

You may find that these figures aren`t identical but this is just down to the delay/latancy in which occurs between State Syncronisations. You should only be concerned if the values are hunreds or even thousands out.

The best way to view the State Table summaries (on SPLAT based firewalls) is to run the command watch 'fw tab -t connections -s'.

Check the State Tables on both nodes, checking for the #VAL totals. It should be somewhat same.. Linearly same.. :-)

So whenever possible, check SYNC Regularly to avoid BREAKUP....
