Hey Twinkle, what your boss wants is not easy, if not impossible. The client side notify scripts don't know what files they've missed - you might be able to code something to trawl through the bpbkar logs - but if you have multi-streaming or detailed logging, it might take too long to process - assuming the file isn't locked anyway - and how do you determine what section of bpbkar is relevant to your job? And if you have multi-streams then the log information from each job is interleaved in the log file too, making it even more difficult.
I'd suggest writing a script to run once a day - say just before your boss typically gets in, that processes/munges/filters/sorts and reports from a "bpdbjobs -all_coulmns" report and then emails your "executive" summary. :) It can be done, I'm not a great programmer, but I did do it.
If you're any good at scripting then it will take you about 40 to 60 man hours to create and hone such a script - and it will be a labour of love - and you'll have created a really useful script. If you can't script, maybe you could pay someone else to create it ;)
The above if for the activity/jobs/session summary - as for missed files...
If you want a report of all files missed across all servers, then this again is no easy task. It can be done ;) I know it can. I've got our sites missed daily missed files down from 700+ to around 20 tough little critters that can't be shifted easily - so it goes. Basically look at the "bperror" command. Filtering the output/processing is weird and wonderful. Best of luck. Or pay someone else to do it?
