When using SySAM sub-capacity licensing, set the SYBASE_SAM_CAPACITY environment variable before installing, or, you can copy in the license key after installation.
Set the SYBASE_SAM_CAPACITY environment variable before starting your installer.
Follow the instructions provided in the SySAM Users Guide > Configuring SySAM Sub-capacity. However, start your installer instead of starting the sub-capacity-enabled Sybase product. The installer includes the sysamcap utility located in sysam_utilities/bin.
