Planned product
maintenance (PPM)
New features are normally first made available with an
RVU before being released in a stand-alone SPR to
ensure that they have been sufficiently integration tested
for the RVU.
Planned product maintenance SPRs usually also include
rolled-up time-critical fix SPRs and defect repair or
product enhancements that are not time-critical fixes.
Planned product maintenance SPRs are always
unrestricted.
Time-critical fix
(TCF)
Introduces fixes that are serious enough that they must
be applied immediately rather than waiting until the next
scheduled RVU. A time-critical fix SPR can be either
unrestricted or restricted.
Unrestricted Can introduce defect repairs, new features, or both.
Unrestricted SPRs are available for specific RVUs and are
available to all customers to select and install individually.
Unrestricted SPRs are generally cumulative: they usually
contain all the fixes and features of a prior SPR. Only
unrestricted SPRs participate in RVUs (that is, are
delivered on a SUT).
An unrestricted PPM SPR is tested and delivered in the
next RVU if it can be used with that RVU. An unrestricted
TCF SPR is verified to be installable on the indicated
RVUs with which it is usable.
After an unrestricted PPM SPR is delivered in an RVU, it
is made available in the Scout for NonStop servers tool.
Restricted A restricted SPR is made available only for a specific
situation, as determined on a case-by-case basis. The
defect repairs and features introduced in the SPR are
usually a one-time solution and access is therefore
restricted.
A restricted SPR that supersedes an unrestricted SPR
contains all the features and fixes present in that SPR. If
you do not need the fix specific to the restricted SPR, you
can install the superseded unrestricted SPR.
