runacct(8)
NAME
runacct - Runs daily accounting
SYNOPSIS
/usr/sbin/acct/runacct [mmdd] [State ...]
DESCRIPTION
The runacct command is the daily accounting shell procedure. This shell
procedure is normally invoked from the cron daemon to process connection,
fee, disk usage, queuing (printer), and process accounting database files
for the current day. The runacct shell procedure produces a
/var/adm/acct/nite/dayacct binary daily accounting file and also produces
summary files, which the prdaily shell procedure uses to generate ASCII
daily file /var/adm/acct/sum/rprtmmdd or to generate files used for billing
for the use of various system resources. The /var/adm/acct/nite/dayacct
binary daily accounting file is used by the acctmerg command.
The acctmerg command adds records from the dayacct file to the
/var/adm/acct/sumtacct file. The /var/adm/acct/sumtacct file is a
cumulative summary of system resources used during the accounting period.
The sumtacct file is used by the monacct command to produce the monthly
accounting summary file, /var/adm/acct/fiscal.
The runacct command has two parameters that you may enter from the keyboard
whenever you must restart the runacct shell procedure. The date parameter,
mmdd, is used to specify the day and month for which you want to rerun the
accounting shell procedure. The State parameter is used to restart the
runacct shell procedure from any of its 13 states. Recovery from a run
failure and the runacct shell procedure restart is described under the
Restarting Runacct heading on the next page.
The runacct command protects active accounting and summary files whenever a
run-time error occurs. During execution, the state-to-state progress of the
runacct shell process is recorded by writing descriptive messages to the
/var/adm/acct/nite/active file. Whenever the runacct shell process detects
a run-time error, a mail message is sent to the superuser (root) and to the
user named adm when environment variable MAILCOM is set to mail root adm.
After writing the mail message the runacct shell procedure aborts.
The runacct shell procedure also creates the temporary file named lock in
subdirectory /var/adm/acct/nite. This file is used to prevent simultaneous
calls to the runacct shell procedure. The runacct shell procedure also uses
the lastdate file, in the same subdirectory, to prevent more than one
invocation of the runacct command per day.
The runacct States
The runacct shell procedure is processed in 13 separate restartable states.
When the runacct process completes each state, the name of the next state
to undergo execution is written to the /var/adm/acct/nite/statefile file.
The runacct procedure processes the various states named in the leftmost
column below, in the order given.
SETUP Moves the active accounting files to working files and restarts
the active files.
WTMPFIX Verifies the integrity of the /var/adm/wtmp file and corrects
date changes when necessary.
CONNECT1 Calls the acctcon1 command to write connect session records.
CONNECT2 Converts connect session records from the /var/adm/wtmp file to
total accounting records in total format defined by tacct
structure members in the private tacct.h header file.
PROCESS Converts process accounting records from the /var/adm/pacct*
file(s) into total accounting records (see CONNECT2 above).
MERGE Merges the connect and process total accounting records.
FEES Converts the output obtained with the chargefee command into
total accounting records (see CONNECT2 above) and merges them
with other total accounting records.
DISK Merges disk accounting records with connect, process, and fee
total accounting records.
QUEUEACCT Sorts queue (printer) accounting records, converts them into
total accounting records (see CONNECT2 above), and merges them
with other total accounting records.
MERGETACCT
Merges the daily total accounting records in the
/var/adm/acct/nite/dayacct file with summary total accounting
records in the /var/adm/acct/sum/tacct file.
CMS Produces command summaries in the file /var/adm/acct/sum/cms.
USEREXIT When the shell procedure /var/adm/siteacct exists, and the
runacct shell procedure enters this state, the /var/adm/siteacct
is called to perform site-dependent account record processing.
CLEANUP Deletes all temporary files and exits.
Restarting runacct
To restart the runacct shell process after it fails, do the following:
1. Check the /var/adm/acct/nite/active file for diagnostic messages.
2. Repair records in any damaged database files, such as /var/adm/pacct
or /var/adm/wtmp.
3. Remove the /var/adm/acct/nite/lock and /var/adm/acct/nite/lastdate
files.
4. Before restarting the runacct shell procedure, you must specify the
mmdd parameter of the runacct command. This parameter specifies the
month and day for which the runacct command is to rerun the accounting
shell process. The runacct shell procedure determines the entry point
for processing by reading the /var/adm/acct/nite/statefile file. To
override this default action, specify a state listed above on the
runacct command line.
It is not a good idea to restart the runacct command in the SETUP
state. Instead, perform set-up actions manually and restart accounting
in the WTMPFIX state by entering the following command:
runacct mmdd WTMPFIX
Should the runacct process fail during its PROCESS state, remove the last
/var/adm/acct/nite/ptacct*.mmdd file before restarting the runacct shell
process because the file does not complete until the next state is entered.
EXAMPLES
1. To start daily accounting procedures for the use of various system
resources, add the following command line to a crontabs file so that
the runacct shell procedure is automatically called by the cron
daemon.
0 4 * * 1-6 /usr/sbin/acct/runacct 2 > /var/adm/acct/nite/accterr
This example shows the instructions that the cron daemon reads and
then executes. The runacct shell procedure runs at 4:00 a.m. (0 4)
every Monday through Saturday (1-6) and redirects errors from the
standard error output (2 >) to the /var/adm/acct/nite/accterr file.
This command typifies accounting instructions normally passed to the
cron daemon from the runacct shell procedure. (See the System
Administration.)
2. To start daily accounting procedures for system resources from the
command line (start the runacct command), enter:
nohup /usr/sbin/acct/runacct 2> /var/adm/acct/nite/accterr&
Although it is preferable to have the cron daemon start the runacct
procedure automatically (see the first example), you may enter the
command from the keyboard. The runacct command will run in the
background, ignoring all INTERRUPT and QUIT signals (nohup), and write
all standard error output (2>) to the /var/adm/acct/nite/accterr file.
3. To restart the system accounting procedures for a specific date, enter
a command similar to the following:
nohup /usr/sbin/acct/runacct 0601 2>> /var/adm/acct/nite/accterr&
In this example, the runacct command is executed on the first day of
June (0601). The runacct process reads the
/var/adm/acct/nite/statefile file to find the state from which to
start. The runacct process runs in the background and ignores all
INTERRUPT and QUIT signals (nohup). The standard error output (2) is
appended (>>) to the end of the file named /var/adm/acct/nite/accterr.
