It is not at all clear what you are asking. A batch job runs in an address space which will be given a certain amount of memory (the precise amount depends upon the site, the exits installed, and the parameters used at the site such as job class, which may have a memory limit). That address space has that amount of memory and it does not matter whether the COBOL program uses 1% or 100% of the memory (although using 100% could cause issues including ABENDS). When the program is not being executed, the system swaps out the address space and swaps in another one. Asking about % utilization of the LPAR makes no sense at all -- are you still talking memory, or are you talking about CPU usage? When you use the term "region", are you referring to CICS or batch jobs? And most sites allow different job classes to use different resources -- so if this is what you are asking, you MUST contact your site support group as we don't work at your site and have no idea what resources are allocated to each job class.
Bandwidth is a term used with networking -- it has nothing to do with memory and memory utilization.
Tell us what problem you are experiencing and we'll help if we can. But don't expect us to read your mind and figure out what you're asking.
