sysconfigdb(8)
NAME
  sysconfigdb - Manage the subsystem configuration database

SYNOPSIS
  /sbin/sysconfigdb {-a	 | -u } [-t target] -f file subsys

  /sbin/sysconfigdb -d	[-t target] subsys

  /sbin/sysconfigdb -l	[-t target] [subsys...]

  /sbin/sysconfigdb {-m	 | -r } [-t target] -f file [subsys]

  /sbin/sysconfigdb -s

OPTIONS
  -a  Adds the specified subsystem entry to the target file.

  -d  Deletes the specified subsystem entry from the target file.

  -f file
      Specifies the input file, a stanza-formatted file that contains entries
      for one or more subsystems.  The default target file is the
      /etc/sysconfigtab file.  Specify another target file by using the -t
      target option.

  -l  Lists the specified subsystem entries in the target file.	 If you do
      not specify subsys arguments, all subsystem entries in the target file
      are listed. The /etc/sysconfigtab file is the default target file.

  -m  Merges subsystem attributes specified in the input file with the
      subsystem attributes in the target file.	If you do not specify a
      subsys argument, all subsystem entries in the input file are merged.
      The /etc/sysconfigtab file is the default target file.

  -r  Removes the subsystem entries specified in the input file from the
      target file.  The only entries removed are those which have attribute
      names and values that exactly match those in the input file. If you do
      not specify a subsys argument, all subsystem entries in the input file
      with exactly-matching attributes are removed from the target file. The
      /etc/sysconfigtab file is the default target database file.

  -s  Synchronizes the /etc/sysconfigtab file and the in-memory configuration
      database by updating the in-memory database so that it matches the
      /etc/sysconfigtab file.

  -t target
      Specifies the target file for the operation. If you do not specify this
      option, the default target file is the /etc/sysconfigtab file.

  -u  Replaces a subsystem entry in the target file with the subsystem entry
      specified in the input file.

OPERANDS
  subsys
      Sepecifies a subsystem that contains the attributes you want to modify.
      The subsystem name and attributes are in a stanza-formatted input file.

      Specify only one subsystem name when you add (-a), delete (-d), or
      replace (-u) a subsystem.

      For other options, if you do not specify a subsystem name the operation
      is attempted for all of the subsystems and attributes specified in the
      input file.

DESCRIPTION
  The sysconfigdb command is used to manage the /etc/sysconfigtab subsystem
  configuration database. However, it can also be used to maintain any text
  file that has the same format as the /etc/sysconfigtab file.	The file
  being managed by the sysconfigdb command is called the target file.  By
  default, the target file is the /etc/sysconfigtab file.

  To specify another file as a target file, use the -t target option.

  To modify a target file, create an input stanza-formatted file, as
  described in stanza(4). This stanza file contains the name of one or more
  subsystems, each with a list of attributes and their values.

  When the target file is the /etc/sysconfigtab file, modifications you make
  to it are automatically synchronized into the in-memory subsystem
  configuration database.  However, the subsystems are unchanged until the
  next time they are configured.

  When the target file is another file, there is no synchronization with the
  in-memory subsystem configuration database.

  For example, suppose you create the following file named table_mgr.stanza
  that defines the attributes for a subsystem named table_mgr_1 and a
  subsystem named tbl_mgr_2:

       table_mgr_1:
		   size = 10
		   name = Ten Element Table
       tbl_mgr_2:
		   size = 5
		   name = Five Element Table

  To add the contents of this file to the /etc/sysconfigtab database and to
  have those modifications synchronized with the in-memory configuration
  database, enter the following commands:

       # sysconfigdb -a -f table_mgr.stanza table_mgr_1
       # sysconfigdb -a -f table_mgr.stanza tbl_mgr_2

  The above example does not change the value of attributes in the running
  kernel.  To modify the value of attributes in the running kernel you must
  do one of the following:

    ·  Use the sysconfig -r command

    ·  Unconfigure and reconfigure the subsystem that contains the attribute
       value

    ·  Reboot your system

  Always use the sysconfigdb command to modify the /etc/sysconfigtab database
  as it automatically updates the in-memory copy of the database.  This
  ensures that the kernel has immediate access to any changes.	 The file is
  also automatically merged during an update installation and changes will be
  merged into the new system.

  To add the contents of the file table_mgr.stanza to another text file named
  /etc/sampleconfigdb, enter the following command:

       # sysconfigdb -a -t /etc/sampleconfigdb -f table_mgr.stanza

  Because the output file is not the /etc/sysconfigtab file, the in-memory
  configuration database is not updated.

  See sys_attrs(5) for information on attribute values.

RESTRICTIONS
  You must be the root user to execute the commmand when the
  /etc/sysconfigtab file is the target file and the operation will modify it.

EXAMPLES
  The following list shows examples of using the sysconfigdb command:

   1.  To replace an existing entry in the /etc/sysconfigtab file, use the -u
       option:

	    # sysconfigdb -u -f table_mgr.stanza table_mgr_1

       The above command replaces the table_mgr_1 entry in the
       /etc/sysconfigtab file with the information in the table_mgr.stanza
       file for the table_mgr_1 subsystem. The command updates the in-memory
       copy of the subsystem configuration database to match the modified
       /etc/sysconfigtab file.

   2.  To merge information in a stanza-formatted file with the
       /etc/sysconfigtab file, use the -m option:

	    # sysconfigdb -m -f table_mgr.stanza tbl_mgr_2

       The above command merges the tbl_mgr_2 information from the
       table_mgr.stanza file with the information already in the tbl_mgr_2
       entry in the /etc/sysconfigtab file. The command updates the in-memory
       copy of the subsystem configuration database to match the modified
       /etc/sysconfigtab file.

   3.  To list the entry for a subsystem in the /etc/sysconfigtab file, use
       the -l option:

	    # sysconfigdb -l table_mgr_1
	    table_mgr_1:
			  size = 10
			  name = Ten Element Table

       The above command does not update the in-memory copy of the subsystem
       configuration database.

   4.  To delete the entry for a subsystem from the /etc/sysconfigtab file,
       use the -d option:

	    # sysconfigdb -d table_mgr_1

       The above command deletes the table_mgr_1 entry from the
       /etc/sysconfigtab file and updates the in-memory copy of the subsystem
       configuration database to match the modified /etc/sysconfigtab file.
