The application server runs in a partition of your VSE system and in a virtual machine of your VM system. To operate the application server, you must be able to start and stop it. If either your VSE installation has CICS, or your VM installation has VSE Guest Sharing and CICS, you must also be able to start and stop the DB2 Server for VSE & VM online support. The online support allows communication through CICS. Parameters for the online support for CICS users are explained in Chapter 2, Managing Online Support.
When starting the application server in a VM environment, you can specify parameters that control the way the application server runs. These parameters control the number of users supported, the amount of virtual storage used, and so forth. This manual shows how to specify the parameters. Appendix A, DB2 Server for VSE & VM Initialization Parameters and the DB2 Server for VM System Administration, and DB2 Server for VSE System Administration describe the meaning of the parameters, and when they should be adjusted.
To view or change the initialization parameters once the application server has started, see Viewing or Changing the Initialization Parameters.
