ppm Tools

• /opt/products/sbin/check_prpm specfile

• /opt/products/sbin/add_prpm specfile

  • parses spec
  • checks for enough space
  • copies all RPMs (including the SRPM)
  • releases all volumes involved

  • ATTENTION for noarch RPMS: add_prpm updated only the database for the current plattform

  • you have to run update_ppmdb

• /opt/products/sbin/update_ppmdb

Reference Installation

• on build hosts

• as root: touch /etc/nosue && mount --bind /opt_tmp/ /opt

• ppm -qFM > /tmp/ppm.cf

• check for enough space
• ppm -vM[x] /tmp/ppm.cf
  • check if volumes released
• rm /tmp/ppm.cf

• as root: umount /opt && rm -vf /etc/nosue

Using populate mechanism to distribute prpm package selections

• cfengine feature products

• Defining variables in cfengine starting with cf_ppm_ followed by a name which can be used for a selections of rpm packages, i.e.

  CF_ppm_sl5
  CF_ppm_desktop
  CF_ppm_theorie
  CF_ppm_server

• Syntax: name prior name prior ...

• name has to correspond to a file in '${CF_PREFIX_PRODUCTS}/archive/${OS_ARCH}/etc/ppm.d' with suffix .cf
• you can define package selections which will be put onto the specified host or host groups.
• CF_ppm_REMOVE special variable to remove packages from the selection
