How SySAM works
Replication Server uses SySAM to “check out” a license for product
functionality, then checks the license back in when the product is no longer in
use. The basic SySAM components are:
• Replication Server linked with SySAM libraries
• One or more local license files
• Optionally, a SySAM network license server
When you install the product, you select whether to configure an unserved
license or a network license server. Both configurations create a local license
file on the same machine as Replication Server in
$SYBASE/SYSAM-2_0/licenses. When you start Replication Server, the
product searches for a license in the default location—$SYBASE/SYSAM-
2_0/licenses—looking at all files with a .lic extension. The local license file
contains the actual licenses or a pointer to a SySAM network license server.
When a license is successfully checked out, Replication Server starts.
Using an unserved license
When you configure an unserved license, Replication Server does not connect
to a network license server, but obtains the required license information
directly from the local license file.
When you use an unserved license configuration, there is no network license
server. In this configuration, Replication Server reads the unserved license and
directly checks out the required license. You activate the licenses for each
machine separately; that is, you do not have centralized control over licenses.
You also do not have asset management or reporting capabilities, and the
license must be rehosted if you move Replication Server from one machine to
another.
When using an unserved configuration, the local
$SYBASE/SYSAM-2_0/licenses directory contains all necessary licenses. You
do not maintain a license server.
