sysconfigtab(4)
NAME
  sysconfigtab - Configurable subsystem definition database file

SYNOPSIS
  /etc/sysconfigtab

DESCRIPTION
  The sysconfigtab file contains initial values for the attributes of
  subsystems that can be dynamically configured.  The information in the
  sysconfigtab file is loaded into an in-memory kernel database when the
  system boots.	 At subsystem configuration time, values in the in-memory
  kernel database override default values coded into the subsystem.

  Avoid making manual changes to this file.  Instead, use the command
  sysconfigdb(8) to make changes.  This utility will automatically make any
  changes available to the kernel and will preserve the structure of the file
  so that future upgrades will merge in correctly.

  The sysconfigtab file consists of formatted entries. The first line in an
  entry specifies the subsystem name.  Subsequent lines specify the
  subsystems' attributes and values.  Comment lines are allowed within an
  entry. The following shows the syntax of a subsystem entry:

  subsystem-name: #This is a comment describing the subsystem
    attribute1 = value1
    attribute2 = value2, value3

  The following list details sysconfigtab entries:

    ·  The subsystem name is terminated with a colon (:).

    ·  Each attribute name and value pair are terminated with a newline
       character.

    ·  Attribute names are separated from values with an equal sign (=).

    ·  Attributes that have more than one value separate the values with a
       comma (,).

    ·  Quotation marks are not used (") in string values. Blank or tab
       characters may occur in the middle of a string, but leading or
       trailing blanks are ignored.

    ·  A number sign (#) appears the beginning of comment lines.

       Comments that are specific to the subsystem are placed the comment
       after the line containing the subsystem name.  The sysconfigdb command
       considers a sysconfigtab entry to begin with the subsystem name and
       end with either the next subsystem name or the end of the file.	Any
       comments that appear before a subsystem name are considered to be part
       of the preceding subsystem and are deleted if the preceding subsystem
       is deleted.

  For a list of the subsystem attributes you can configure, see the System
  Administration manual.  For information about loadable device driver
  attributes, see the Writing Device Drivers: Tutorial manual.

RESTRICTIONS
  The maximum length of a stanza entry is 40960 bytes.	An entry cannot
  contain more than 2048 fields (lines).

  The maximum length of a stanza field is 500 bytes.

EXAMPLES
  The following shows an example stanza entry that could appear in the
  configurable subsystem database:

       proc:
		   max-proc-per-user = 64
		   max-threads-per-user = 256

  The preceding entry defines the max-proc-per-user and max-threads-per-user
  attributes for the proc subsystem.
