Administration Guide

Accounting files

All accounting data, report, and summary files reside in the /var/adm directory. The accounting data files belong to members of the adm group, and all active data files (such as wtmp and pacct) reside in the adm home directory, /var/adm.

Note
The System Administrator should monitor the capacity of the /var file system when exclusive use accounting is enabled because large /var/adm/pacct files may be created and accounting will save the excl_Spacct files in the /var/adm/acct/nite directory. This may require the administrator to periodically increase the /var file system size or remove unnecessary excl_Spacct files. The System Administrator may edit the /usr/lpp/ssp/bin/nrunacct script in the CLEANUP section to automatically remove excl_SPacct files.

Data files

Data files are:

/var/adm/acct/nite/dacct: Contains disk total accounting records, created by the dodisk command.
/var/adm/fee: Contains output from the chargefee command, in ASCII tacct records.
/var/adm/pacct: Active process accounting file.
/var/adm/wtmp: Active login accounting file.
/var/adm/Spaccti.yyyymmdd: Contains process accounting files for yyyymmdd during the execution of the nrunacct command.

Report and summary files

Report and summary files reside in the /var/adm/acct subdirectory. You must create the following subdirectories before the accounting system is enabled.

/var/adm/acct/nite: Contains files that nrunacct and crunacct command use in daily accounting.
/var/adm/acct/sum: Contains the cumulative summary files that nrunacct and crunacct update daily.
/var/adm/cacct: Contains files that the crunacct command uses in daily accounting.

nrunacct command files

The following report and summary files, produced by the nrunacct command, are of particular interest.

/var/adm/nsiteacct: Contains site-specific accounting procedures for node accounting.
/var/adm/acct/nite/lineuseyyyymmdd: Contains usage statistics for each terminal line on the system. This report is especially useful for detecting bad lines. If the ratio between the number of logouts and logins exceeds 3 to 1, it is possible that a line is failing.
/var/adm/acct/nite/daytacctyyyymmdd: Total accounting file for the previous day.
/var/adm/acct/sum/daycmsyyyymmdd: Contains the daily command summary.
/var/adm/acct/sum/loginlogyyyymmdd: Contains a record of the last time each user ID was used.
/var/adm/acct/nite/rebootsyyyymmdd: Contains beginning and ending dates from the wtmp file and a listing of system restarts.

crunacct command files

/var/adm/csiteacct: Contains site-specific accounting procedures for cluster accounting.

These files are copied to the acct_master node during crunacct execution.

/var/adm/cacct/node/nite/lineuseyyyymmdd

/var/adm/cacct/node/nite/daytacctyyyymmdd

/var/adm/cacct/node/nite/rebootsyyyymmdd

/var/adm/cacct/node/sum/daycmsyyyymmdd

/var/adm/cacct/node/sum/loginlogyyyymmdd

The node level files are merged to become:

/var/adm/cacct/sum/class/tacctyyyymmdd.

/var/adm/cacct/sum/class/daycmsyyyymmdd.

which in turn update cumulative summary files:

/var/adm/cacct/sum/class/tacct file..

/var/adm/cacct/sum/class/cms file..

Files in the /var/adm/acct/nite directory

active: Used by the nrunacct command to record progress and to print warning and error messages. The file active.yyyymmdd is a copy of the active file made by nrunacct after it detects an error.
jobcharge: Contains a floating point number used to determine the number of charge fee units to charge a user for exclusive use of the node and its value is in units of seconds per charge fee unit.
jobrecs: Contains start job and end job records used for accounting on jobs that make exclusive use of nodes.
ptacct.yyyymmdd: Contains summary version of pacct files.
ctmp: Contains connect session records during nrunacct
accterr: Contains standard error messages produced during the execution of the nrunacct command.
lastdate: Indicates the last day the nrunacct command executed, in yyyymmdd format.
lock: Used to control serial use of the nrunacct command.
statefileyyyymmdd: Used to record the current state during execution of the nrunacct command.
wtmperror: Contains wtmpfix error messages.
owtmp.: Contains the previous day's wtmp file.

Files in the /var/adm/cacct/ directory

active: Used by the crunacct command to record progress and to print warning and error messages. The file active.yyyymmdd is a copy of the active file made by crunacct after it detects an error.
lastdate: Indicates the last day the crunacct command executed, in yyyymmdd format.
lock: Used to control serial use of the crunacct command.
statefileyyyymmdd: Used to record the current state during execution of the crunacct command.
lastcycle: Indicates the date of the last successfully completed crunacct cycle.
fiscal_periods: Defines the start date of each fiscal period.

Files in the /var/adm/cacct/sum directory

class/cms: Daily command summary.
loginlog: File listing current login records.
rprtyyyymmdd: Saved output of the cprdaily routine executed in crunacct.
<class>/tacct: Process account summaries.

Files in the /var/adm/cacct/fiscal directory

/var/adm/cacct/fiscal/class/cmsmm: Total class summary file for the month, in binary format.
/var/adm/cacct/fiscal/class/tacctmm: Total accounting file for month, in binary format.
/var/adm/cacct/fiscal/fiscrptmm: Report similar to that of the prdaily command for month, in binary format.
