One question about SAR: Invalid system Activity File

Problem:
# Sar-q
Invalid system Activity File:/var/log/sa/sa04 (0x5)

Analysis Process:
1. Google: Get the following information:

From: http://sebastien.godard.pagesperso-orange.fr/faq.html

2. A different version of the SAR command that is suspected to be generating the SA data file and the resolution SA data file
# which SAR
/usr/local/bin/sar # This is my command to read the SA data file, version number 8.0.0
# sar-v
Sysstat version 8.0.0
(C) Sebastien Godard (sysstat <at> orange.fr)

3. How do I know which version of SAR is being used to generate the SA data file?
Typically these files are written in Cron, so grep the cron configuration file: (Note: grep SA is not grep SAR)
# grep Sa-r/etc/cron*
/ETC/CRON.D/SYSSTAT:*/10 * * * * ROOT/USR/LIB/SA/SA1 1 1
/etc/cron.d/sysstat:53 * * * root/usr/lib/sa/sa2-a

#/usr/lib/sa/sa1-v
Sysstat Version 7.0.2
(C) Sebastien Godard

4. Why is this happening?
The 7.0.2 version of SAR is in the/usr/bin/directory, and the $path variables in my execution environment are as follows:
# echo $PATH
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin

First we found the SAR under/usr/local/bin.

Solution: (Write the full path of SAR)
#/usr/bin/sar-q
