Re: How to implement OPS on HP-UX

Hi,

 We have implemented OPS on HP-UX. You have to run ServiceGuard for OPS; that's that OS layer that allows OPS to communicate between servers. What you don't have to run is the full blown SG "failover" piece.

 We are running our clusters on N class boxes running HP-UX 11.00 64-bit. We are using EMC for our disk solution, but I don't know the details of how the connectivity is done. There is something called "shared LVM" whichh is needed to keep the disk definitions in sync. You probably knew this, but you have to use RAW disk. The only weirdness that I saw in Oracle on RAW was that you can only have 1 datafile per LV. In other words, there is no concept of offsets when you define a datafile, so the UX people have to define the LV's to the size that you need for your datafiles.

 If you are going to run 8.1.6, I would highly recommend using 8.1.6.2.0. We ran into a problem where if one server goes down the listener does not automatically reset the MTS connections for the down server unless you are on 8.1.6.2.0.
