Checking RAM memory in Solaris is a crucial task for system administrators and users to ensure that their system has sufficient memory to run applications and processes smoothly. RAM, or Random Access Memory, is a volatile memory that stores data and instructions that are currently being processed by the CPU. Monitoring RAM usage helps identify potential performance issues, memory leaks, or hardware problems.
There are several commands available in Solaris to check RAM memory usage. The most commonly used command is ‘prtconf’, which displays a detailed report of the system’s hardware configuration, including the amount of installed RAM. Another useful command is ‘vmstat’, which provides real-time statistics about the system’s memory usage, including the amount of free and used memory. For more detailed information about memory usage by specific processes, the ‘pmap’ command can be used.
