Oracle集群时区

1.环境及问题

OS:SUSE 12SP3
DB:12.2.0.1.190115 2节点RAC
Q:集群日志的时间和主机时间相差较大

grid@WWJD1:~> date
Mon Feb 11 12:08:03 CST 2019

下面的日志是刚刚重启完集群的日志，与当前时间相差较远

grid@WWJD2:/oracle/app/grid/diag/crs/WWJD2/crs/trace> tail -f alert.log
2019-02-10 19:53:49.758 [CRSD(269859)]CRS-1012: The OCR service started on node WWJD2.
2019-02-10 19:53:49.805 [CRSD(269859)]CRS-1201: CRSD started on node WWJD2.

从上面的时间来看总共慢了16个小时左右

2.环境检查

--------------------------
1)检查OS时区

cat /etc/sysconfig/clock
env|grep -i tz

2)检查CRS时区
su - grid
cd $ORACLE_HOME/crs/install/
grep -i tz s_crsconfig_*_env.txt

grid@WWJD1:~> cat /etc/sysconfig/clock
TIMEZONE="Asia/Beijing"
DEFAULT_TIMEZONE="US/Eastern"
grid@WWJD1:~> env|grep -i tz
LS_COLORS=no=00:fi=00:di=01;34:ln=00;36:pi=40;33:so=01;35:do=01;35:bd=40;33;01:cd=40;33;01:or=41;33;01:ex=00;32:*.cmd=00;32:*.exe=01;32:*.com=01;32:*.bat=01;32:*.btm=01;32:*.dll=01;32:*.tar=00;31:*.tbz=00;31:*.tgz=00;31:*.rpm=00;31:*.deb=00;31:*.arj=00;31:*.taz=00;31:*.lzh=00;31:*.lzma=00;31:*.zip=00;31:*.zoo=00;31:*.z=00;31:*.Z=00;31:*.gz=00;31:*.bz2=00;31:*.tb2=00;31:*.tz2=00;31:*.tbz2=00;31:*.xz=00;31:*.avi=01;35:*.bmp=01;35:*.fli=01;35:*.gif=01;35:*.jpg=01;35:*.jpeg=01;35:*.mng=01;35:*.mov=01;35:*.mpg=01;35:*.pcx=01;35:*.pbm=01;35:*.pgm=01;35:*.png=01;35:*.ppm=01;35:*.tga=01;35:*.tif=01;35:*.xbm=01;35:*.xpm=01;35:*.dl=01;35:*.gl=01;35:*.wmv=01;35:*.aiff=00;32:*.au=00;32:*.mid=00;32:*.mp3=00;32:*.ogg=00;32:*.voc=00;32:*.wav=00;32:
grid@WWJD1:~>
grid@WWJD1:/oracle/app/12.2.0/grid/crs/install> grep -i tz s_crsconfig_*_env.txt
#This file can be used to set values for the NLS_LANG and TZ environment
#2. The Time zone setting can be changed by setting the TZ entry to
#   the appropriate time zone name. For example, TZ=America/New_York
TZ=GMT+08:00   >>>>>>>>>>>TZ=Asia/Shanghai

3.实施方案

1.修改CRS时区配置文件
su - grid
vi $ORACLE_HOME/crs/install/s_crsconfig_*_env.txt
TZ=GMT+08:00   >>>>>>>>>>>TZ=Asia/Shanghai
2.重启集群
crsctl stop crs
crsctl start crs

附：Linux 时间/时区查看

date -R
timedatectl|grep "Time zone"
cat /etc/timezone
