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:
#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.
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.
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.
The following shows an example stanza entry that could appear in the
configurable subsystem database:
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.
Commands: sysconfig(8), sysconfigdb(8), cfgmgr(8)
