This exit is the result of SHARE requirement SSMVSE11018 that I authored and submitted in July 2011: <SSMVSE11018> Title: Contents Supervisor Exit Description: An exit is needed that will pass information about the module just fetched into or about to be removed from virtual storage by the contents supervisor. The information should include information available today to CSVINFO/CSVQUERY invokers such as 1) module name, 2) virtual storage extent list, and 3) information that can help determine the MVS data set name or z/OS UNIX directory from which the module was fetched. The CSV exit should also be called for directed LOADs, even though the information passed by the system might be only a subset of what is available for other module fetches and there will be no module DELETE for this case. Benefit: CSV monitoring is needed by asset management products, application profilers, debuggers and other similar software programs. Today, such programs monitor module fetch by intercepting important system service entry points such as SVC routines. These are completely unintended interfaces, thus no documentation exists describing how to insert the intercept, how the intercept code must behave, or how to handle the situation that arises when more than one product must intercept the same system service. These system interfaces are very sensitive and serious system instability can arise from such programming. Solution:The exit should be able to be dynamically activated by more than one product running in a z/OS image. Impact if no solution provided: Software providers will continue to use unintended (and 'dangerous'!) interfaces to monitor CSV activity.
