User can specify the virtual hostname
(relocatable IP). The deploysappkgs(1)

is not explicitly part of the SAP (server-side)
configuration, and only gets detected and
pre-set in the package configuration by
deploysappkgs(1) if it follows the naming
convention of having an alias hdb<SID>, in
all other cases the IP address needs to be
added to the package configuration manually.
