CHAPTER 1 Before You Begin
Installation Guide for UNIX 13
Replication Server continues to operate normally until the issue causing the
license failure is fixed, or until the grace period expires. The error message
indicates the date and time the grace period is scheduled to end. The error log
entry is repeated with increasing frequency while Replication Server operates
in the grace period until you fix the issue causing the license failure. When the
issue is fixed, Replication Server automatically acquires the license and moves
from grace period mode into normal mode. If Replication Server cannot obtain
the license before the grace period expires, Replication Server stops running.
Note If you obtain a Replication Server license from a network license server,
Replication Server periodically executes a heartbeat with the network license
server. A successfully acquired license could be invalidated during the
heartbeat; for example, if the license has an expiration date or the network
license server was restarted and other Replication Server instances acquired all
available licenses before this instance could reacquire a license. If this happens,
Replication Server enters a grace period. This information is written in the
error log, and is similar to the information written to the error log when you
initially start the product.
