In z/OS, many patches need to be restarted before the system can take effect. In the Sysplex environment, it is often used in the form of rolling IPL, that is, the mass shutdown system, rather than all systems shut down together. In this process, the abnormal shutdown of the USS system often causes the shutdown process of the entire system to not proceed normally. One reason for the USS System not to shut d

How to Use the Smem command line to check the memory usage on Ubuntu To check the memory usage in Ubuntu Linux, we can install and use the Smem memory reporting tool to display the memory usage in Ubutnu Linux. Smem is a command line tool used to check the memory usage, percentage, or chart of each process in Linux. Smem is a tool that provides a large amount of memory usage reports on Linux systems. Different from existing tools, smem can report the ratio set size (PSS), which is a more meaning

processes use it.RSS isn't an accurate representation of the memory usage for a single process. pss differs from RSS in so it reports the proportional size of its shared libraries, i.e. If three processes all use a shared libraries that have pages, that library would only contribute pages to the PSS t Hat is reported for each of the three processes. PSS is a very useful number because if the PSS for all processes in the system be summed together, that's a G Ood representation for the t

When your computer slows down, the first thing to do is to release the memory. Especially in a multi-user environment and a server environment that executes key tasks, memory consumption becomes more critical because multiple users and application threads will compete for more memory space at the same time.

the processes in the system are added together by PSS, and that is the sum of the memory that is consumed by the system. When a process is killed, the shared library memory that it occupies is shared by other processes that still use the shared library. In this way, PSS can also be misleading, because when a process is killed, PSS does not represent the amount of memory the system recycles. Uss:unique Set Size the physical memory that the process occupies on its own .This pa
