Hi Pawel, We do, indeed, duplex the Lock and SCA structures. I am not able to pull out the overhead of doing this but my feeling is that it is very low. We have two data sharing groups. The SCA and Lock structures of both are in one ICF and duplexed to the other ICF. I highly recommend doing this.

Do you duplex DB2 lock structures i.e. _LOCK and _SCA structure? What is the overhead connected with it? In our 2-node PS environment we don't have stand-alnone CF, only internal CF in two different footprints. We want to avoid situation when damage of one of the boxes will bring the whole DB2 sharing group down.
