Exadata Compute Cloud Time Zone Change

Hi Everyone

Yesterday I wrote about the timezone  change steps on Oracle Compute Classic instance. Today I am putting the steps for Exadata Cloud Service cluster timezone change.

This involves little more steps that what we did on Classic compute instance. This requires downtime of instance running on the node. 




Stop CRS on node1
As a root user

crsctl stop crs 

[root@lpcldv0244m ~]# cat /etc/sysconfig/clock
ZONE="UTC"
UTC=true
ARC=false
[root@lpcldv0244m ~]# cp -p /etc/sysconfig/clock /etc/sysconfig/clock.01192018
[root@lpcldv0244m ~]# vi /etc/sysconfig/clock

[root@lpcldv0244m ~]#  cp /opt/oracle.cellos/cell.conf /opt/oracle.cellos/cell.conf.01192018

change UTC
to 
America/Phoenix

 [root@lpcldv0244m ~]# grep Timezone /opt/oracle.cellos/cell.conf
  America/Phoenix
[root@lpcldv0244m ~]#
[root@lpcldv0244m ~]# cd /u01/app/12.2.0.1/grid/crs/install
[root@lpcldv0244m install]#cp s_crsconfig_lpcldv0244m_env.txt s_crsconfig_lpcldv0244m_env.txt.01192018

Change Timezone
 
[root@lpcldv0244m install]# grep TZ= s_crsconfig_lpcldv0244m_env.txt
#   the appropriate time zone name. For example, TZ=America/New_York
TZ=US/Arizona
[root@lpcldv0244m install]#
Start CRS stack now

crsctl start crs
Once your Databases come up, start your apptier nodes.
Happy Learning!!
