There can be only one Advisor active in the sysplex at any given time, unless you are using sysplex subplexing. In a sysplex subplexing environment, this step requires additional actions. For information about the changes to this step, see Configuring Advisors in a subplexing environment.
The Advisor reads configuration data from one file, which might exist as a z/OS® UNIX file, a PDS or PDSE member, or a sequential data set. If you plan on allowing the Advisor to move within the sysplex in the case of failure, you probably want the Advisor configuration file or data set to exist on shared DASD, to make it accessible to all systems in the sysplex if necessary. The Advisor configuration file is specified on the CONFIG DD statement in the Advisor start procedure. A sample start procedure is provided in EZBLBADV in SEZAINST.
The Advisor configuration file serves three basic purposes:
