  • startstop_sol

    v1 v2  
    88== Details == 
     9Startstop is a system-specific module; the configuration file described here is for the Solaris version. On startup, startstop changes to the directory specified by the EW_PARAMS environment variable. Then it reads the configuration file named startstop_sol.d. This file sets up all parameters required to run an Earthworm system. In the configuration file, lines may begin with a valid startstop command (listed below) or with a # to denote a comment. Command names must be typed in the configuration file exactly as shown in this document (upper/lower case matters!). 
     11=== Example startstop_sol.d Configuration File === 
     15#       Startstop (Solaris Version) Configuration File 
     17#    <nRing> is the number of transport rings to create. 
     18#    <Ring> specifies the name of a ring followed by it's size 
     19#    in kilobytes, eg        Ring    WAVE_RING 1024 
     20#    The maximum size of a ring is 1024 kilobytes. 
     21#    Ring names are listed in file earthworm.h.

     40#    Class must be RT or TS 
     41#    RT priorities from 0 to 59

     44#    If the command string required to start a process contains

     49#       the command will be run. Make sure they are valid names! 
     50#       You cannot use "root" as the Agent user. If an earthworm module 
     51#       needs to run as root, you should make that module's binary setuid root.

     95=== Functional Commands === 
     96Unlike most other Earthworm modules, startstop expects the lines in its control file to be in a certain order. Below are the commands recognized by startstop, grouped by the function they influence and listed in the order in which they must appear in the control file. All commands are required! 
     98==== Shared memory setup ==== 
     99nRing                   required 
     100Ring                    required (nRing) 
     102===== nRing ===== 
     103nRing nRing 
     105Specifies the number of shared memory regions (aka transport rings) that startstop will create for "public" use by the modules of this Earthworm system. nRing should be an integer from 1 to MAX_RING (currently defined to be 50). 
     107Example:  nRing 3 
     109===== Ring ===== 
     110Ring name size 
     112Specifies the name and size, in kilobytes, of one transport ring. There must be exactly nRing "Ring" commands following the "nRing" command in the startstop_sol.d. name is a character string (up to 19 characters long, valid strings are listed in earthworm.d) that relates (in earthworm.d) to a unique number for the key to the shared memory region. size should be an integer between 1 and 1024 (the default maximum size). When deciding how large to make a memory region, realize that the transport layer uses a portion of the memory region for its own bookkeeping. The region size is NOT required to be an even multiple of the size of the messages it will contain. However, suppose you want the region to be exactly large enough to store NUM messages of size MSGSIZE. To include space for transport bookkeeping too, the region size (in bytes) should be: 
     113sizeof(SHM_HEAD) + NUM * ( sizeof(TPORT_HEAD) + MSGSIZE ) 
     115where SHM_HEAD and TPORT_HEAD are structures defined in transport.h. Startstop places all of its outgoing messages in the memory region specified by the first "Ring" command. 
     117Example:  Ring  WAVE_RING 1024 
     119==== Startstop-specific info ==== 
     120MyModuleId              required 
     121HeartbeatInt            required 
     122MyClassName             required 
     123MyPriority              required 
     124LogFile                 required 
     125KillDelay               required 
     126HardKillDelay           optional 
     127maxStatusLineLen        optional 
     128Stderr                  optional 
     130===== MyModuleId ===== 
     131MyModuleId mod_id 
     133Sets the module id for labeling all outgoing messages. mod_id is a character string (up to 30 characters, valid strings listed in earthworm.d) that relates (in earthworm.d) to a unique single-byte number.     Startstop places its outgoing messages on the shared memory ring specified by the first "Ring" command in startstop_sol.d. 
     135Example:  MyModuleId MOD_STARTSTOP 
     137===== HeartbeatInt ===== 
     138HeartbeatInt nsec 
     140Defines the number of seconds, nsec, between TYPE_HEARTBEAT messages issued by startstop. Startstop places its heartbeats on the shared memory ring specified by the first "Ring" command in startstop_sol.d. 
     142Example:  HeartbeatInt 30 
     144===== MyClassName ===== 
     145MyClassName class 
     147Sets the process class for startstop. class is a character string that must be set to either "RT" (for Real-Time) or "TS" (for Time- Share) on solaris. 
     149Example:  MyClassName RT 
     151===== MyPriority ===== 
     152MyPriority priority 
     154Sets the process priority for startstop. See the "Class/Priority" command below for allowed values. After startstop reads its configuration file, it changes its own class/priority to the values specified in the "MyClassName" and "MyPriority" commands. 
     156Example:  MyPriority 4 
     158===== LogFile ===== 
     159LogFile switch 
     161Sets the on-off switch for writing a log file to disk. If switch is 0, no log file will be written. If switch is 1, startstop will write a daily log file(s) called cfname_yyyymmdd.log where cfname is the name (without extension) of startstop's configuration file (ex: startstop_sol) and yyyymmdd is the current UTC date (ex: 19960123) on the system clock. The file(s) will be written in the EW_LOG directory (environment variable). 
     163Example:  LogFile 1 
     165===== KillDelay ===== 
     166===== HardKillDelay ===== 
     167===== maxStatusLineLen ===== 
     168===== Stderr ===== 
     170==== Earthworm modules to run ==== 
     171Process                 required \ 
     172Class/Priority          required  |  one set 
     173Stderr                  optional  | per module
