Updating the running system is "frowned upon". The way that I do maintenance is to put the maintenance onto an alternate set of OS volumes. That is easy to do with "legacy" datasets. However, to update z/UNIX files, the container dataset must be "mounted" on the updating system. So, the /Service subdirectory is where you mount your alternate z/UNIX filesystems. Think of it as a similar to the SSA alias used in SMP/E to refer to the datasets on your alternate RES volumes via that normal catalog. So, you'd first MOUNT your alternate ROOT filesystem dataset on the /Service subdirectory. You'd then mount your alternate VAR filesystem at /Service/var, XML at /Service/usr/lpp/ixm, SHPUROOT at /Service/usr/lpp/ported, SHPHROOT at /Service/usr/lpp/php, SHPEROOT at /Service/usr/lpp/perl, MQS at /Service/usr/lpp/mqm, and so on. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
