Shared memory is a region of memory that can be accessed by multiple processes. This can be useful for sharing data between processes, such as when multiple processes need to access the same data or when data needs to be shared between processes on different machines.
In Solaris 10, there are a few ways to check shared memory. One way is to use the ‘ipcs’ command. The ‘ipcs’ command will list all of the shared memory segments that are currently in use. Another way to check shared memory is to use the ‘shmctl’ command. The ‘shmctl’ command can be used to get information about a specific shared memory segment, such as the size of the segment and the number of processes that are attached to it.
