    Problems with routing on global zone - multiple default gateways

    Hi All, I'm experiencing problems with routing on Solaris 10u8, sun4u. The traffic to the global zone fluctuates, i.e. enters with one interface, and exits with another (after some time), thus breaking the session. There are 3 zones running, out of which one was migrated from another machine...

    Monitoring IO performance

    Hi All, As in the title. What to use? I have a 2-node cluster (SC 3.2) with latest update of Solaris 10 running. There are 20 Oracle databases running on both nodes, and the used filesystem is VxFS. The goal is to provide IO utilization statistics over a 14-day period. I tried to use vxstat...

    Local Zone Security

    Hi All, A friend of mine has suggested recently that since the Solaris zone feature relies on software-level isolation (as opposed to hardware-level isolation, as with AIX LPARs), then it is theoretically possible to break out of the local zone to the global zone. My question is: has anything...
