History and Compression configuration changes.

[peregineme]

When making changes to /etc/cron.d/sysstat concerning the intervals and counts for sa1, I see that these are effective once I close the file.
However, I see that when I did a change in /etc/sysconfig/sysstat to set COMPRESSAFTER=1, the files older than one day were not compressed, nor were new sa files created the next day compressed when they were one day old.
Is there some command we need to run to update the configuration?
In the Documentation, there is information on how to install the package, but not on how to make configuration changes.

[sysstat]

/etc/sysconfig/sysstat file is read by sa1 and sa2 scripts at run-time:

# Read configuration file, overriding variables set above
[ -r ${SYSCONFIG_DIR}/${SYSCONFIG_FILE} ] && . ${SYSCONFIG_DIR}/${SYSCONFIG_FILE}

So nothing should be done to make the change effective. Just edit the configuration file, save it (and make sure it is world readable).

It seems both the COMPRESSAFTER and HISTORY actions are executed by sa2 for both sa and sar files.
sa2 was disabled in /etc/cron.d/sysstat, but once I enabled it, the history cleanup and file removal happened.
