Having read the posts and comments, I think it becomes clear that the SAS admin does have to be some "jack-of-all-trades" meaning that knowledge is (preferably) required of SAS, SAS Administration (metadata) and how the SAS components interact.

What I do somewhat miss is that with the fact that nowadays a SAS environment is spread amongst various operating systems (Windows, Unix, Linux). More and more you need to also have knowledge on how to perform actions on the different platforms including performance measurement, halting and (re)starting processes, and so on.

As such, the "Jack of all trades" not only applies to the different components within SAS but also to various operating systems.

Is the above just my perception, which maybe comes from the fact that as a consultant I work in various environments, or do others experience the same?
