Managing Model Variable Lists
The com.wrq.vhi.sconfig package contains methods for managing model variable lists on Host Integrator Servers. This makes it possible for you to update username/password lists for hosts that enforce regular expiration of usernames and passwords, hosts that only allow a credentialed user one concurrent host session, and so forth. Use the classes in the com.wrq.vhi.sconfig package to manage the model variable lists on any Host Integrator Server in your domain.
Code Samples
Show model variable lists
/* Example Program :
NOTE: As of the 7.0 release AADS has been replaced with the Management Server. Although references to
AADS still remain in the APIs the code samples will work with the Management Server.
Display model variable lists and their contents.
Compile: javac -classpath sconfig.jar;bc-fips-1.0.1.jar;bctls-fips-1.0.7.jar ShowMVLs.java
Run: java -classpath .;sconfig.jar;wcp.jar;bc-fips-1.0.1.jar;bctls-fips-1.0.7.jar ShowMVLs <ManagementServerName> <ServerName>
Before running this program, edit the username and password variables to provide credentials for a user that is
part of the Administrator profile.
