Calculating System Parameters for UNIX and Linux B.1 Determine Memory and Disk Requirements This section outlines the basic system requirements for most systems. Because these requirements vary by platform, consult your platform documentation for additional information. B.1.1 Calculate Memory Requirements Use the breakdown of memory usage shown in the following table to calculate the memory your system needs for Caché. UNIX Memory Requirements Components Operating system Caché Global database cache Routine cache User overhead Network (if present) Memory Requirements 1800 KB (operating system dependent) 842 KB 8 KB per buffer 32 KB per routine buffer 1024 KB per process 300 KB per port for each network system process (DMNNET, DCP, and RECEIVE). Caché ports have two DMNNET system processes per port. In addition, there is a network shared memory requirement, which depends on the number of ports and the number of remote hosts configured. For a basic system, this requirement is about 304 KB. By default, Caché automatically allocates shared memory, including routine buffers and global buffers, to a total of one-eighth of the system available shared memory space. If you plan to run large applications or support large numbers of users, tune the system according to the following formula: (number of routine buffers)*32 KB + (number of global buffers)*8 KB + 4 MB ___________________________________ = Shared memory needed 70 Caché Installation Guide
Determine Memory and Disk Requirements B.1.2 Calculate Swap Space The amount of swap space available on your system should never be less than the amount of real memory plus 256 KB. With this minimum in mind, InterSystems recommends the following value as the minimum amount of swap space needed for Caché: ((# of processes + 4)† * (1024 KB)‡ + total global buffer space + total routine buffer space _____________________________________ = Minimum swap space † You add 4 to the # of processes for the Caché Control Process, the Write daemon, the Garbage Collector, and the Journal daemon. You should also add 1 for each slave Write daemon. The # of processes must include all user and jobbed processes which might run concurrently. If you are running networking, add 1 for the RECEIVE system process plus the number of DMNNET daemons you have running (2 per port). If your system is a server, add the number of DCP processes that will be created when all potential clients access the server. ‡ The 1024 KB number is approximate. It is based on the current size of the Caché executable and grows with the partition size you allocate to each Caché process. On most systems, provide only as much swap space as necessary. However, some systems require you to provide swap space for the worst case. Under these conditions, you need to increase this number to as high as 1.5 MB, depending on the partition size you specify. Be sure to confirm that your UNIX system permits the amount of swap space you require. For specific information about swap space on your system, consult your UNIX operating system manual.
