licenses out, enter the machine name and port number for the Network
License Manager license daemon. The default port number is 29722. A
simplified license is written out that contains ifnormation to direct
Adaptive Server to contact the remote license daemon to check out
licenses.
Otherwise select cancel and the License Entry application exits. See
“Sybase Software Asset Management” for more details.
Environment variables
Add entries to your login script (.login) so that Sybase environment variables
area always set. An example of this is contained in
/Applications/Sybase/System/SYBASE.csh. If you do not have a .login script in
your home directory, you can use the .cshrc file. By default, user accounts do
not contain a .login or a .cshrc script and you must create one. If you do not,
the login daemon looks to /etc/csh.login and /etc/csh.cshrc.
