CHAPTER 1 Before You Begin
Installation Guide for UNIX 11
Some Windows and Linux machines use technologies such as “Hyper
Threading” which presents one physical CPU as two logical CPUs. This is still
considered one CPU for counting licenses.
License availability and grace periods
If Replication Server cannot obtain a suitable license, the product does not run.
A license is considered unavailable if it cannot be checked out, or if the license
cannot be issued during a grace period. Licenses can be unavailable during
start-up or heartbeat runtime.
When SySAM detects a checkout failure, the event is logged in the Replication
Server error log, which you can use to diagnose any unexpected licensing
failures. After the initial checkout failure, periodic events are logged during a
grace period.
If a suitable license cannot be found when requested, Replication Server
evaluates if a license can be issued during a grace period. There are three types
of grace periods:
• Install time – when you configure a new Replication Server (or upgrade an
earlier version to 15.0), you have 30 days to activate and configure the
appropriate license.
• Runtime – a runtime grace period is evaluated when one of these
conditions occurs:
• A license was not checked out at start-up, but there is a history of
successfully using the requested license on this machine.
• A license that was successfully checked out at start-up becomes
unavailable at a later time.
If Replication Server encounters either situation, it enters into a 30-day
runtime grace period. If the problem is not resolved within 30 days,
Replication Server stops running; however, the user can save any work and
exit. If the problem that causes the license to be unavailable is fixed during
the runtime grace period, Replication Server automatically picks up the
license and no longer operates in the grace period.
• Support renewal time – this grace period allows you enough time to update
the license after renewing support. The support grace period for
Replication Server is one year.
This means that you can install and use EBFs and updates that are released
up to one year past the end-of-support date recorded in the license.
