Schmidt# Description: Test the Informix database backup## Change Log## Date Name Description.................# 05/30/01 Peter R. Schmidt Start Program################################################################################### Purpose# ------# The archecker is designed to validate a level 0 archive without# impacting the production system, ensuring that all data required to# restore a system exists on the archive tapes in the correct format.## Features# --------# - Checks a level 0 archive after the archive has completed# - Verification need not be done on the machine hosting the OnLine system.# - Minimal system resources are required, even for large archives.# - Restartable at tape level.# - Detects missing pages and indicates affected table(s).# - Can also verify data in similar fashion to oncheck -cd.# - Progress monitor# - Creation of the INFO directory give many usefull reports about the archive.## Setup and Operation# -------------------# Set the environment variable AC_CONFIG to the name of your# configuration file. Otherwise $INFORMIXDIR/etc/ac_config.std is# used by default. If no valid config file is found, archecker will# print an error message and exit.## A sample configuration file:# ----------------------------## AC_STORAGE /tmp# AC_MSGPATH /home/informix/logs/archecker.log# AC_TAPEDEV /dev/rmt/0# AC_TAPEBLOCK 16# AC_VERBOSE 1## Valid Configuration file parameters# -----------------------------------## AC_STORAGE# The name of a directory where temporary files# are kept. The amount of space required is determined# by two factors: the number of chunks and the number of tables.# To give you a guide, a 50GB OnLine system should take about 20MB# (your mileage may vary).# DEFAULT: your current directory.## AC_MSGPATH# Pathname of archecker's message log. All error# and status messages will be placed in this file.# DEFAULT: ./msg.log## AC_TAPEDEV# Name of the tape device.# DEFAULT: NONE## AC_TAPEBLOCK# The size of the tape block in KB. It must match the# blocksize used for the archive, otherwise an error# will indicate the correct blocksize to use.# DEFAULT: NONE## AC_VERBOSE# 0 Do not be verbose# 1 Verbose output# DEFAULT 0## Command Line Usage# -----------------# archecker may be invoked by itself or with the following options:## -v Enables the verbose output# -d Cleanup any temporary files from a previous run.# -s Display the verbose message to the screen.# -t Use ontape tape device# -H to get a basic usage method# -R To restart at the last sync point (i.e. tape)# -V to get the current tool version# -b Direct XBSA access# -D Delete old files and EXIT# -F Retrieve list of pages off the archive# -P Read Performance - info only# -T Restart at a specific tape## Recommended Usage:## archecker -tdsv## Verbose Option# --------------# With the verbose option on, dots are to the screen--one# for every 25MB of data read from the tape. Each line of# dots represents 1GB of data. ################################################################################## Note: if LOGFILE1 matches the AC_MSGPATH parameter in the ac_config.std file,# then this will effectively rotate the log file.LOGFILE1=$INFORMIXHOMEDIR/logs/archecker.logLOGFILE2=$INFORMIXHOMEDIR/logs/archecker.log.OLD if [ -f $LOGFILE1 ]; then if [ -f $LOGFILE2 ]; then rm -f $LOGFILE2 fi mv $LOGFILE1 $LOGFILE2 rm -f $LOGFILE1 fi###############################################################################time archecker -tdsv # Note: if you want to run archecker in background and your backup is only# one volume of tape, you can do it this way...### time archecker -tdsv <<-EOF# 1# 0# EOF################################################################################# Send log file via e-mailgrep -v "partition file" $LOGFILE1 | mailx -s "Archecker" username@mydomain.com###############################################################################</XMP><CENTER><TABLE border=2 cellspacing=0 cellpadding=0><TR><td><A HREF="../index.shtml" CLASS=CLASS1> Home </A><td><A HREF="../resume.shtml" CLASS=CLASS1> Associates </A><td><A HREF="../references.shtml" CLASS=CLASS1> References </A><td><A HREF="../downloads.shtml" CLASS=CLASS1> Downloads </A><td><A HREF="../elite1.shtml" CLASS=CLASS1> Elite </A><td><A HREF="../links.shtml" CLASS=CLASS1> Links </A><td><A HREF="../contacts.shtml" CLASS=CLASS1> Contact Us </A></TR></TABLE></CENTER></BODY></HTML>⌨️ 快捷键说明
